- Q: What are the advantages and disadvantages of flat gate valves?
- The disadvantage of flat gate valve is that when the medium pressure is low, the sealing force of the metal sealing surface is insufficient, so as to achieve satisfactory sealing. On the contrary, when the medium pressure is high, if the sealing surface is not lubricated by the system media or foreign media, often opening and closing may cause the sealing surface to wear too much. Another disadvantage is that the circular motion of the circular gate in the circular flow, only when it is at the valve closed position of 50%, this valve is more sensitive to flow control. Moreover, the gate will produce severe vibration when it breaks the high-speed and dense medium flow. The valve seat can also be throttled if the seat is made of a V - shaped opening and is tightly oriented to the gate.
- Q: what are their applicable conditions? Advantages and disadvantages?
- The gate valve is one of the simplest valves. Generally manual, most of the electric valve failure, as a manual. Butterfly valve is more, I saw the pneumatic butterfly valve, that is, with gas control closed, general and solenoid valve matching.Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.
- Q: What is the difference between gate valves Z41W-16R and Z41W-16P?
- According to JB/T308P stands for Cr-Ni stainless steelR stands for Cr-Ni-Mo stainless steelCr-Ni stainless acid resistant steel has CF8, CF3, F304, F304L, which applies to the medium of work, such as nitric acid oxidation acid.Cr-Ni-Mo stainless acid resistant steel has CF8M, CF3M, F316 and F316L, which is suitable for working medium, such as acetic acid and reducing acid.
- Q: Gate valve Z41H-16Q generally used for what place?
- Commonly used in petroleum, chemical systems, especially in long-distance pipelines of petroleum and natural gas.
- Q: What else, P54140V, 170V? What do they mean?
- P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar
- Q: What are the main types of gate valves?
- According to the different materials for carbon steel valves, forged steel valves, stainless steel valves, cast steel valve, iron gate, ceramic valve;
- Q: Why the valve can only be fully open and fully closed valve can adjust the flow?
- Valve, if adjusted, it is easy to wash the sealing surface, resulting in sealing surface damage.
- Q: Is the gate valve flanged?
- The most commonly used gate valves are threaded connections, flanged connections, and welded connections.Like the outer thread connection, the clamp connection, the card sleeve is seldom used.
- Q: Generally, how big is the diameter of the installation flange plate gate valve?
- Under normal circumstances:Flanged gate valves for piping over DN50,DN50 (below) can be made of wire or gate valves, or flanged gate valves (flanged valves or welded gate valves)
- Q: What is the difference between gate valve Z41T and Z45T?
- Valve Z41T and Z45T difference is that "41" is dark rod, that is, the screw is not out of the turbine,"45" is the bright rod, that is, the screw out of the turbine.Common points are copper sealed gate valves.
