Q: I would like to ask how the valve entry, for a new pair, really difficult, what cutaway view, there are other, just contact the valve less than a week, and sometimes it is really difficult to understand. Forget the experienced teacher can be generous with your criticism to later, indebted forever, learn the valve Comrades some help.In a company CAD to relatives as soon as possible to a company, and then slowly improve, I do not know what is the request of the novice, and how to start as soon as possible, I am learning routine is: give me a set of valve design drawings, and then I paint it on, do not understand the structure and workshop look. I wonder if you have any good learning methods that can be referred to and supplemented by younger brother: May learn some basic knowledge of valves, learning in practice, relatively fast.

Q: Measure the temperature with a thermocouple, and then how to make the valve open when the temperature reaches a certain value. When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!: Switching type (one on and off)Block digital display with the upper and lower limit control valve opening and closing is goodProbably more than 100Regulating type (to keep temperature at a constant value)With PID valve position regulator can be very good controlAbout 300 more

Q: Pump, valve, these belong to the material?: In the stainless steel industry category: sheet only belongs to the material! In the mechanical and electrical equipment categories: valves in the screws, gaskets, nuts are materials! This is relative!

Q: What does the whole copper valve mean?: Except the handwheel, all the material of the valve body is copper

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: What valve does the high pressure by-pass valve DN254 * 800 belong to?: You want to ask the classification or valve DN254 mean?. The data you gave was incomplete. No answer.

Q: What are the key valve enterprises in China? Mainly in those areas?: The region, the largest number of Wenzhou. Focus on the valve business, Zhongyuan District Kaifeng high pressure valve factory, Zhengzhou Zheng butterfly valve on behalf of the butterfly valve. Shanghai region, Tianjin, northwest Lanzhou high pressure, Suzhou area, northeast Tieling region, Dalian, Shenyang and so on. And the Zigong area

Q: What kind of valves are best used for sand drain valves?: Suzhou ATW Valve Co. Ltd production of sealing ball valve, Suzhou ATW Valve Co., according to the condition of solid particles, long-term research and in practice, and achieved good results in the condition of solid particles.
