- Q:What's the meaning of the ball valve bore 14 "x 12"?
- Should refer to imports 14 inches, export 12 inches, this kind needs to make to order, at present domestic possibly not yet.
- Q:What are the uses and characteristics of copper ball valves?
- 4, good sealing performance5, the direction of installation is not limited, the flow of media can be arbitrary
- Q:Is the integral type split ball valve structurally identical?
- The utility model is characterized in that the desktop is connected between the valve body and the valve sleeve, the gasket can effectively prevent leakage of the valve, the flow direction of medium after transformation can be used in two-way, which greatly facilitate the industrial pipeline installation.
- Q:Check valve, ball valve, check valve are used in what place, ah?
- The cut-off valve is generally used in the inlet pipe, the outlet valve is generally used in the official website, convenient switch, check valve is to allow water to flow past the water directed, anti back, generally used in vertical pipe, the equivalent of the pump valve
- Q:What is the difference between ball valve Q41F-16C and Q41F-16P?
- Q41F-16C ball valve material is carbon steel, Q41F-16P material is 304. No difference between the others. I hope you'll be satisfied.
- Q:I design water meter transformation, 50WPD table, the original table before the installation of 50 anti-theft valve, table after the installation of 50 of the globe valve; master let me put anti-theft valve into anti-theft gate valve. Switch the stop valve to the gate valve. I'd like to ask what kind of valve is appropriate Why? And I checked from the Internet that the ball valve is generally used for small aperture, this aperture range is how much? Why?No copy paste, thank you......
- 2, shortcomings:Because the main valve seat seal material is PTFE, it has almost all the chemical substances are inert, and the friction coefficient is small, stable performance, easy to aging, temperature range and excellent sealing characteristics of a comprehensive. But the physical properties of PTFE include high expansion coefficient, sensitivity to cold flow, and poor thermal conductivity. The design of seat seals must be carried out around these characteristics. Therefore, when the seal material hardens, the reliability of the seal will be damaged. What's more, polytetrafluoroethylene has a lower temperature range and can only be used at less than 180 degrees centigrade. Over this temperature, the sealing material will age. Consider long-term use, usually only at 120 degrees does not use.Its regulating performance is worse than the cut-off valve, especially pneumatic valve (or electric valve).Two, scope of application:Ball valves are used in petroleum refining, long distance pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries.
- Q:DN20 copper ball valve with large PPR converter connector
- See how big your tube is. 20 tubes are straight with 20*1/2 internal teeth, and 25 tubes are straight with 25*1/2 internal teeth
- Q:What does one inch of an ice ball refer to?
- Ball valve inch refers to the nominal diameter of the valve is 1 inches, that is, DN25 valve1 and 1/2 is DN40's.. More than an inch on a pipe. The valve is half done with DN
- Q:Our factory has part of the ball valve in the direction of movement and normal ball valve is the opposite direction: anti clockwise for the turn off, clockwise. Excuse me, what's the reason for this?Excuse me, is this because the valve body installs the reason of the contrary or the reason, the ball valve is thus designed?Are there any positive and negative points when the ball valve is installed?
- Ball valve is 90 degrees switch, you may put the handle of the wrong position, change 90 degrees, try it
- Q:Is the ball valve ball valve?
- The hemisphere valve has two kinds, one is no eccentric, the valve seat is always close the valve, the valve must be made (such as the V type ball valve etc.).
