Packing of Control Valves
Application of Control Vavels
- Q: Remove the handle and lever the stem rotation with a wrench,
- First you know what valve you need, or you know where to use the pipe material, so you do not need to understand the valve material.
- Q: How to suppress the valve?
- Valve pressure is generally divided into 2 parts. One is shell pressure test, one is sealing test pressureShell pressure test is 1.5 times the pressure of the valve. For example, the pressure on your valve is 16 pressure. Then the shell test pressure will reach 24 pressureThe pressure on the seal is 1.1 times the pressure of the valve. For example, the pressure on your valve is 16 pressure. Then the pressure test on the seal will reach 17.6 pressure. That's all right.
- Q: How about leaking water pipe valve?
- It depends on where the place is leaking.1, if it is household valveA, the valve and pipe connections at the leakage, in the connection, do not rub tape (the best counter clockwise direction, so that when the valve is connected, the more twisted the more tight) ;B, if the valve itself in the leak, there are ways, it is necessary to open the valve, in which to add sealed or O ring, but it is recommended to replace a more convenient.2, if it is industrial valvesA, industrial valves leaking, if not the valve itself in the leak, then in the valve and pipe connections to join the sealing ring,B, if the valve itself is leaking, it is best to return to the manufacturer for maintenance, if not convenient, then only the manufacturers to come here for maintenance.
- Q: What does the 4 point valve mean?

- This is the discharge valve, the lower part of the handle protruding part of the valve is the sealing device. The overall material should be brass, which is typically made by equipment manufacturers.
- Q: If the valve in the pipeline throttle, such as open and open 50%, the valve before and after the pressure of how to calculate, how the flow changes?
- the preset pressure after the valve, thus maintaining the dynamic pressure balance valve, and non compressible medium, mainly for the purpose of regulating the flow, especially in the petrochemical industry, power industry, if the specific calculation of a valve is more difficult, but a lot of data will provide the valve valve opening and flow of the corresponding graph, the landlord is really interested in learning more, can go to the Xinhua Bookstore to find the valve selection manual valve related content, which will introduce calculation method.
- Q: How do I open the gas valve?
- First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open.

It's different from place to place. Some are pulled out half, and some are pulled out.
- Q: What are the uses and differences of gate valves, butterfly valves, ball valves and other valves?
- Valve and ball valve is generally used in the main pipe, long-term use, butterfly valve is often used frequently,
- Q: Where is it installed, what is the role, what is the material, and are there other alternatives instead of this effect?
- Main stem to prevent leakage, there are PTFE and graphite and so on. There are no other good products to replace.
- Q: How much is the 150LB of the valve?
- Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.
