Q:What are mine valves?
You want to see what works on the use of what media, in the choice of what type of valve is more appropriate. Shanghai HuquanValve manufacturers, veteran enterprises, trustworthy.
Q:What is the normal temperature on the valve?
What's the valve?. Conventional valves are 425 degreesIf it's on the oil field. It's only 120 degreesAt normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees
Q:How do you calculate the flow of the valve?
Valve flow calculation value is very vague, pipe pressure, back pressure, medium viscosity, medium temperature, valve structure, and so on, will affect the calculated value.
Q:What's the valve specification DN20?
You should be asking, how many inches?DN20 is 3/4
Q:How do you calculate the pressure difference between the front and rear of the valve?
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 to suppress the valve?
How does the valve press the pressure test pump?. How much pressure do you need to use the pressure pump for the corresponding specifications?. There is a specially suppressed machine pressure test pump. How much pressure do you need to use the pressure pump for the corresponding specifications?
Q:What does the torque of the valve mean?
Unit: Newton M. torque is the minimum torque used to turn on the valve. It is the force that opens the valve!The valve that indicates the opening of the PZ73X-10C DN50 requires 5 meters of force.
Q:Internal structure of valve
To answer your question was the top valve is not open on the thread of an analogy between ordinary wood screws and nails is a straight out of another can only rely on the screwdriver to turn out the cut-off valve is from the mechanical analysis of text as a specific principle is not specific
Q:What's the valve as a unit?
Business now there are many valve manufacturers, with the rapid expansion of SMEs, SMEs are more ~!
Q:Symbols for all types of valves
Look at the attachment I gave you. The legend of the valves is complete!
