- Q: What are the advantages and disadvantages of flat gate valves?
- The advantage of flat gate valve is that the flow resistance is small, and the flow resistance is similar to the flow resistance of short valve. The flat gate valve with guide hole is installed on the pipeline and can be directly cleaned with the cleaner. As the gate is sliding on the two seat surface, the flat gate valve can be applied to the medium with suspended particles, and the sealing surface of the flat gate valve is actually positioned automatically. The seat seal surface is not subject to thermal deformation of the valve body. Moreover, even if the valve is closed in cold condition, the thermal elongation of the stem will not cause the seal to be subjected to overload. The length of the structure is much shorter than that of the ball valve, and it is easier to start. Light plate gate valve is more refined, but the effect is exactly the same.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 is the difference between the model z81x-16q and z81x-16c of the groove gate valve?
- Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel
- Q: Gate valve Z41H-16Q generally used for what place?
- It is a standard flanged gate valve with engineering pressure 1.6MPa. Generally used in chemical processes, of course, can also be used for municipal and civil engineering. The valve is generally used for cutting occasions fully open or fully closed, is not suitable for flow regulation.
- Q: What is the standard for ductile iron gate valve set?
- Fujian - mark light - valve for you to answer:Whether it is the next shot or dark bar, directly flanged valves can be installed, usually apply eighth copies, if the industrial pipeline is apply sixth copies, sixth copies to apply separate sets of flanges and bolts (bolts independent fee).
