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 gate DH10016, AM: The first Z represents the gate valve (the initial consonant of the Chinese phonetic alphabet for the gate); the second 2 represents the drive mode of the valve, that is, electro hydraulic drive.

Q: Function of signal butterfly valve and gate valve: The signal butterfly valve applies to petroleum, chemical, food, medicine, papermaking, water and electricity, ships, water supply and drainage, smelting, energy and other system pipelines. It can be used as regulating and throttling devices in a variety of corrosive, non corrosive gases, liquids, semi fluids, and solid powder pipelines and containers. It is widely used in high buildings, fire protection systems and other piping systems that need to display valve switching status.

Q: What does gate z41t-10 150 mean?: According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150

Q: Stainless steel gate valve DN150 200300 weight, who knows?: It depends on different materials and pressure levels. 304 material, high pressure weight will be much heavier.

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: What are the common standards for gate valves?: 1, product standardsGeneral purpose valves, flanged connections, iron gate valves, GB/T 12232-2005General requirements for steel valves GB/T 12224-2005"Steel flat gate valves for pipelines" JB/T 5298-91Inspection and test of valves. JB/T 9092-1999Standard for safety evaluation of drinking water distribution equipment and protective materials GB/T 17219-1998

Q: Does the tap belong to a stop valve or a gate valve?: Most faucets are stop valves,Part of the faucet is plug valve,Hot water nozzles are almost all plug valves.

Q: What is the allowable leakage rate of the gate valve D?: In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.

Q: What is wire feed gate valve? What do you say in French?: Should refer to the threaded valve. Refers to the valve body with internal thread or external thread, and pipe thread connection. Also called thread valves, threaded valves, valves within the toothFlange gate valve is connected to the flange gate valve, this connection is the most common way.We also introduced a lot of threaded valve, can go to the front pages.The main difference is the threaded valve connectionI only know their English, I'm sorry I can't help youBox thread valveFlange valveThreaded valve, screw connected with the valve, should be said that the former is the most professional.
