The gate (gate valve) is a gate 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.Gate valves for Class150 ~ 2500, the working temperature of -29 to 425 DEG C (Tan Gang) or -29 to 500 DEG C (stainless steel) small caliber pipeline, used to cut off or connect the line of medium, use different materials, can be separately applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea etc. a variety of media, the 3 Classification valve according to the different classification methods can be divided into: the parallel gate valve, wedge gate valve, valve lift, rotating rod valve, quick opening and closing valve, reduced valve, flat gate valve etc.. 4, characteristics of fluid resistance is small, applicable pressure, temperature range, medium flow direction is not restricted, good sealing performance
Gate valve structure, upstairs said about the same, but it can only rough adjustment flow, you may drive it to 30%, he will flow through 65% traffic, you can drive him to 70%, he also flow through 75% traffic. However, the fluctuation is small and can be used for rough adjustment of flow. What's more, half open and half closed are some of the effects on their life span.
Valve in the pipeline can only be fully open and fully closed off, can not be adjusted and the throttle. Gate valve is a valve used in a wide range, generally more than 50mm caliber DN block device is selected it, sometimes cut off very small aperture devices are used to gate valve, gate valve is used as cut-off media, when in full flow through the whole, when the media is running a minimal pressure loss. Gate valves are normally used in situations where they do not need to be frequently opened and closed, and the gate is fully open or fully closed. Not used as an adjustment or throttling. For high speed moving medium, the gate can cause the vibration of the gate under the condition of partial opening, and the vibration may damage the sealing surface of the gate and the valve seat, while throttling will cause the gate to suffer the erosion of medium.
Like other valves, the gate valve is used to block fluid flow. 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.
