Thermal power plant valves with pressure plugging technology Power plant valves are mainly used to control the operation of fluid media on various equipment and pipelines. Leakage of valves often occurs on packings, flange seals, and valve bodies. Valve leakage can cause long time Erosion of the valve stem and flange sealing surface can eventually make the valve obsolete, plus the medium fluid thermal power plant valve pressure plugging technology power plant valve is mainly used to control the operation of fluid medium on various equipment and pipelines, valves Leakage often occurs on packings, flange seals, and valve bodies. Leakage of the valve for extended periods of time can cause erosion of the valve stem and flange sealing surfaces. Eventually the valve can be scrapped, and loss of fluid in the medium can increase the power plant's consumption. , The غير مجاز مي باشدt rises and the economic benefits decline. If the media fluid is toxic, flammable, explosive, corrosive, etc., it will easily cause poisoning, fire, explosion and other casualty accidents and accelerate the corrosion rate of the plant equipment, shorten its service life, seriously pollute the surrounding environment, and destroy power Production damages people's health. The existence of leakage seriously threatened safety production and increased unplanned shutdowns in power plants. The following describes some valve leakage causes and plugging methods as well as methods of maintenance and maintenance of valves for reference.

1. Forms and Factors of Valve Leakage Leakage and Causes of Valve Packing During the operation of the valve, there is relative movement between the valve stem and the packing, which includes rotation and axial movement. With the increase in the number of switches, the number of relative movements also increases, as well as the effects of temperature, pressure, and the characteristics of the fluid medium, and the valve packing is the most likely to leak. It is caused by the gradual weakening of the contact pressure of the filler, the aging of the filler itself, and the loss of elasticity. At this time, the pressure medium will leak outward along the contact gap between the packing and the valve stem, and will blow out part of the packing material for a long time and flush the valve stem out of the groove, thereby expanding the leakage.

2. Flange Leakage The flange seal of the valve is mainly based on the pre-tightening force of the connecting bolt, and the gasket can reach a sufficient sealing specific pressure to prevent the leakage of the sealed pressure fluid medium. There are many reasons for its leakage. The pressing force of the sealing gasket is insufficient, and the roughness of the bonding surface does not meet the requirements. The deformation of the gasket and the mechanical vibration will cause the leakage of the sealing gasket and the joint surface of the flange. . In addition, when the bolts are deformed or extended, the gaskets are aged, the resilience is reduced, cracks, etc., can cause the flange surface to leak tightly. Flange leakage also can not be ignored man-made factors, such as the gasket biased, so that the partial pressure than the pressure less than the excessive force, exceeding the design limit of the gasket, and flange fastening process uneven force or two methods The offset of the centerline of the blue line, which causes false tightening, is prone to leakage.

3, the valve body leakage and reasons The main reason for the leakage of the valve body is due to valve casting production or forging defects caused by, such as trachoma, air holes, cracks, etc., while the fluid medium erosion and cavitation is also caused by the valve body leakage Common factors.

3.1 The principle of pressure plugging The principle of pressure plugging is based on the liquid medium in the dynamic conditions, the solid sealing material sealing mechanism is the basic basis. The method is to install a special equipment at the leakage part, utilize the chamber formed between the sealing part and the special equipment, and inject the sealant into the chamber with a special high-pressure injection glue tool, and fill the entire chamber space to squeeze the sealant. The force balances with the pressure of the leaking medium and establishes a new sealing structure to block the pasغير مجاز مي باشدes of the leaking pores and to block the leakage of the medium.

3.2 The advantages of pressure plugging reduce social and economic losses.

There is a lack of doors in every home, and each door lacks matching locks. A matching lock can make the door more functional and have the finishing touch. However, if a door is not locked, security cannot be guaranteed. It may be that the lock is an integral part of the door. In the case of door locks, door locks, channel locks, bathroom locks, etc. are used according to the purpose, and ball locks, handle locks, and mortise locks are divided by shape. According to the use of the door locks, bedroom locks, channel locks, bathroom locks, etc.; according to the shape of ball-type lock, handle lock, mortise lock, lock and so on. Ball locks and handle locks have three functions: lock, handle, and touch ball. And you need to install a door handle separately.

This requires a good door with a good lock, what kind of door with what kind of lock, but you know how to pick a good lock it? Nowadays, there are a wide variety of hardware locks on the market, and the similarity of styles has caused many ordinary consumers to have headaches. So how to pick a good hardware lock on the door, lock experts Fu Shili to give you support, and master the following four look very important.

First, look at the lock material The market's locks are basically divided into stainless steel, copper, zinc alloys, aluminum alloys and iron and other materials. Each of these materials has its own advantages and disadvantages.

Stainless steel has high strength, strong corrosion resistance and does not change color. It is the best material for making locks, but its forging performance is not good. The style and color of stainless steel door locks are relatively simple. The copper material has superior mechanical properties and is generally used to make European high-grade door locks. The price and grade are relatively high. Zinc alloy has strong wear resistance, corrosion resistance and other properties, and is relatively easy to cast, can design a lot of styles and patterns, the current hot locks on the market are a lot of zinc alloy material. However, due to the difference in the ratio of zinc alloy and raw materials, and the different design process casting process, the price difference is very large. The use of aluminum alloy and iron is relatively small. The aluminum alloy is mainly made of aluminum. This type of door lock design is generally relatively simple, there is no pattern design, and iron-type door locks are now less and less, basically belong to the low-end door locks. There are many kinds of locks, and there are locks for different materials and grades. The main thing is to look at your own budget and style, choose a big brand, and the brand and quality are relatively guaranteed.

Second, look at the lock surface treatment The surface treatment of the lock can be broadly divided into three kinds: electroplating, spraying and coloring. The locks form a layer of dense protective film on the surface of the product through surface treatment, which can play a role in anti-corrosion and anti-rust, and make the lock more beautiful and durable. The dense protective film is also a measure of the quality of locks. Good quality locks are mostly plated. The coating is delicate and smooth, even and moderate, bright in color, free of bubbles, signs of rust and oxidation. For instance, the hardware products of Tiannu hardware are all through layer plating process and road polishing process, 48-hour moderate salt spray test or 200-hour low-level salt spray test to ensure that the product surface does not appear spotted and oxidized on the surface due to use and time lapse. Rusty.

Third, look at many types of key keys, generally divided into a word key (ordinary keys and angle keys), cross keys, computer keys,

In the case of cylinder keys, etc., the key locks for different key configurations are not the same. The ordinary key and cross key configuration locks are relatively inexpensive, but the anti-theft performance is relatively poor and they are class A door locks. As the anti-theft performance is relatively low, the public security department vigorously promotes the use of Class B and Class C. These two types of door locks have a relatively high manufacturing process. The more complex the patterns of the keys, the lower the chance of successful imitation, and some brands such as Tenuta Hardware. Luxury door locks have a unique password card, if the new key must be assigned to a designated professional institution with a password card to enable key matching, which greatly improves anti-theft performance.

Fourth, to see the implementation of standards for locks Hardware locks abroad have very strict standards and regulations, so the quality of imported products is relatively high. We can feel the locks by hand. In general, the feeling of heavy locks, the quality is relatively high; the lock body can not be exposed, the exposed tip is easy to hurt, in particular, should pay attention to the lock handle end of the lock, the lock tongue and the lock body four corners;

The lock spring has a good lock to open, high sensitivity and long service life. Locks also have a variety of styles, and must be consistent with the style of the interior doors.

The main problems solved by this debugging:

Increase the upper limit setting frequency of the induced draft fan to allow our company to set the upper limit frequency, but it must not exceed 55HZ.

Replace the differential pressure transmitter that meets the actual testing requirements.

With the external programmers of our company, the communication between the PLC program and the computer was carried out.

Check the spray drying oil level to guide our staff to maintain the dehumidifier.

I personally and the workshop staff know more about the centrifugal towers of your company. We are not qualified enough for preschools in this industry. There are still some blind spots in the maintenance of operating equipment. I beg your company to arrange experienced professional commissioning personnel for our technology. Principles of personnel and operation staff, operation and maintenance of equipment (including but not limited to equipment startup and shutdown, equipment cleaning, equipment monitoring and adjustment techniques, water film dust removal tower cleaning monitoring, dehumidifier maintenance and replacement of efficient filtration, replacement of lubricants and other maintenance Possible emergency response) Of course, some of the maintenance details can be given to our maintenance personnel by dialing.

In the early signing of the contract, we requested to provide relevant key parameters in addition to electronic detection components, but also the need for mechanical instrumentation on-site monitoring display, so that timely detection of measurement and measurement instrument failure. For example, the temperature increases the bimetal thermometer in the field, which has been proposed in the technical agreement.

Windows doors require good sealing performance, and the micro-positive pressure does not leak powder. It is recommended to use the pressure tower window door. It is best to arrange for personnel to replace the first phase of the tower window door.

Spray Dryer Fan Cooling Water Inlet and Outlet Aperture Thread No. is not matched with our company's silk head. If it is convenient, please contact us to supply water for welding.

The interior of the dehumidifier is seriously corroded by the galvanized sheet. The internal temperature probe cannot detect the temperature and there is no humidity monitoring data. Please contact the dehumidifier manufacturer for maintenance.

Gravity Casting Parts

"Gravity Die Casting. A permanent mould casting process, where the molten metal is poured from a vessle of ladle into the mould, and cavity fills with no force other than gravity, in a similar manner to the production of sand castings, although filling cn be controlled by tilting the die."

Gravity Die Casting

Sometimes referred to as Permanent Mould, GDC is a repeatable casting process used for non-ferrous alloy parts, typically aluminium, Zinc and Copper Base alloys.

The process differs from HPDC in that Gravity- rather than high pressure- is used to fill the mould with the liquid alloy.

GDC is suited to medium to high volumes products and typically parts are of a heavier sections than HPDC, but thinner sections than sand casting.

There are three key stages in the process.

1. The heated mould [Die or Tool] is coated with a die release agent. The release agent spray also has a secondary function in that it aids cooling of the mould face after the previous part has been removed from the die.

2. Molten metal is poured into channels in the tool to allow the material to fill all the extremities of the mould cavity. The metal is either hand poured using steel ladles or dosed using mechanical methods. Typically, there is a mould [down sprue" that allows the alloy to enter the mould cavity from the lower part of the die, reducing the formation of turbulence and subsequent porosity and inclusions in the finished part.

3. Once the part has cooled sufficiently, the die is opened, either manually or utilising mechanical methods.

Advantages

• Good dimensional accuracy

• Smoother cast surface finish than sand casting

• Improved mechanical properties compared to sand casting

• Thinner walls can be cast compared to sand casting

• Reverse draft internal pockets and forms can be cast in using preformed sand core inserts

• Steel pins and inserts can be cast in to the part

• Faster production times compared to other processes.

• Once the tolling is proven, the product quality is very repeatable.

• Outsourced Tooling setup غير مجاز مي باشدts can be lower than sand casting.
