1. It has the advantages of simple and compact structure, reasonable design, reliable sealing, light and flexible operation, small size, smooth channel, low resistance, easy installation and easy disassembly.

2. When the valve is fully opened, the flow resistance coefficient is very small, and the valve will eliminate the function of the valve disc and the dirt on the sealing surface every time the valve is opened and closed.

3. The packing is made of flexible graphite ring and graphite packing, reliable sealing, light and flexible operation.

4. It is widely used in oil and water steam pipelines such as petrochemical industry and thermal power plants to connect or cut off the intermediate quality of pipelines. The sealing surface of the opening and closing device has compact structure and reasonable design.

Q: Classification of flat gate valves

A: Plate gate valve can be divided into guided plate gate valve, no deflector plate gate valve, high pressure water injection plate gate valve, gas plate gate valve, flange plate gate valve, welded plate gate valve, clamp plate gate valve, single plate plate gate valve and double plate plate gate valve.

Now the use of plate gate valve is more and more widespread, many pipelines are using plate gate valve to replace the ordinary wedge gate valve.

 

Q: What are the mechanical properties of copper alloy and carbon steel?

A: 1. Mechanical properties of copper alloy

Copper alloy is an alloy material with a high copper content, usually composed of copper and other metals (such as zinc, nickel, etc.) mixed. Compared with carbon steel, the electrical and thermal conductivity of copper alloy is much better, which is one of the reasons why it is widely used in electronics, communications and other fields. However, the strength and hardness of copper alloys are relatively low, and some copper alloys differ greatly from ordinary steel in strength and hardness.

 

2. The mechanical properties of carbon steel

Carbon steel is a mixture of carbon and iron alloy material, with high strength and hardness, is widely used in the manufacture of mechanical parts, tools and so on. However, compared with copper alloy, the electrical and thermal conductivity of carbon steel is poor, and it is not suitable for some occasions with high requirements for electrical and thermal conductivity. In addition, carbon steel is easy to rust, easy to wear and other disadvantages.

 

3. The difference between copper alloy and carbon steel

The mechanical properties of copper alloy and carbon steel are quite different: copper alloy has excellent electrical and thermal conductivity, but relatively low strength and hardness; Carbon steel, on the other hand, has higher strength and hardness, but poor electrical and thermal conductivity. In addition, copper alloy has strong corrosion resistance and certain wear resistance, which has a wide application prospect in some special occasions; Carbon steel is widely used in machinery manufacturing, construction and other fields.

 

4. Conclusion

In summary, the mechanical properties of copper alloy and carbon steel are different, and different materials should be selected according to the specific use occasion. Factors such as electrical conductivity, thermal conductivity, strength and hardness, as well as special properties such as corrosion resistance and wear resistance, need to be considered.

 

Q: How many types of brackets are available? How many section types are there?

A: According to the different installation methods of the valve stem nut and the support, the support can be divided into the following three types.

① Valve stem nut bracket, mainly used for handwheel operated valves.

② Column beam bracket, mainly used for small diameter valves or low pressure valves.

③ The flange connecting bracket is mainly used to install large diameter valves with various control mechanisms.

 

Q: What items should be calculated in the design of open rod and dark rod wedge gate valves?

A: In the design of open rod and dark rod wedge gate valves, the following items should generally be calculated:

1. Valve body thickness;

2. The total force and calculated specific pressure on the sealing surface;

3. Strength of valve stem;

4. Stability of the valve stem;

5. The thickness of the gate;

6. Strength of the middle flange;

7. The strength of the middle flange connection bolt (at normal temperature, at initial heating, at high temperature);

8. Strength of valve cover;

9. Strength of support;

10. The strength of the support connecting bolt;

11. Total torque and circumferential force of handwheel;

12. Strength of valve stem nut;

13. Strength of other main components, etc.
