Gate is one of the most common open/close, use of ram (namely the open-close part, in the gate opening and closing a called ram or gate, gate called ram block) to connect (full open) or truncation (seated) line in the medium.It does not allow for river closure, use should be avoided in the open gate trace, because of the erosion of high-speed flow of medium will accelerate the damage of the sealing surface.Double DE gate at the channel center line perpendicular to the gate of the one-sided as lifting movement, like gate cutting medium pipeline, so as the gate valve.

Q:What do you mean by "2" and "200 CF8M"?
CF8M is 316,2 "is 50200 caliber stainless steel pressure (American Standard, LB)
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:Why does the centrifugal pump start and stop in the case of closing the gate valve?
The centrifugal pump starts and stops in the case of closing the pump outlet valve. Start off the pump outlet valve is to reduce the starting current, stop when the pump is closed, the outlet valve is to reduce water hammer, prevent blade from bad.
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.
Q:Function of gate valve
Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle.
Q:Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?
In the standard JB/T5296-1991 "universal valve flow coefficient and the flow resistance coefficient test method",
Q:What is an inverted seal gate valve?
The inverted sealing gate valve is provided with an inverted sealing device, and when the valve is fully opened, an inverted seal is formed, and the filling can be changed under the normal operation of the system.
Q:What is a protective gate valve? What is gate valve knowledge?
Door gate, refers to the design of anti blocking nuclear explosion shock wave from the pipe into the project inside the valve, composed of a valve body, valve seat, valve plate and wave absorbing device, wave absorbing device leakage hole in the valve body, valve leakage hole is a cylindrical hole, wave valve has two door sealing groove between the cylindrical hole and wave valve double seal ring seal, between the valve body and the flange is double sealing ring seal.
Q:What kind of gate valve is Z6CS-H102?
Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr
Q:The legend of gate valve and stop valve
The working principle is different. The stop valve is an upward stem type, and the handwheel rotates and rises with the stem. Valve is hand wheel rotation, stem upward movement. Flow is not the same, the gate valve requires full open, the cut-off valve is not the same. The gate valve has no inlet and outlet direction requirements, and the cut-off valve has the required inlet and outlet!Gate valve and stop valve are shut-off valve, is the most common two valves.From the exterior, the gate valve is shorter than the cut-off valve, especially the bar valve needs a higher height space. Valve sealing surface has a certain degree of self sealing capacity, its spool depends on the media pressure tight contact with the valve seat sealing surface, to achieve tight leakage. Wedge gate valve spool angle is generally 3~6 degrees, when forced to shut down excessive or temperature changes of the valve core is easy to die. Therefore, high temperature and high pressure wedge gate valve, in the structure have taken certain measures to prevent spool stuck. The valve in the opening and closing valve and valve seat sealing surface contact and mutual friction is always so easy to wear sealing surface, especially in close off the valve, the valve before and after the great pressure, sealing surface wear is more serious.
