Gate valve opening and closing pieces is the gate, the direction of movement of the gate and fluid perpendicular to the gate valve can only be fully open and closed, not suitable for regulation and throttling. The gate has two sealing surfaces. The two most commonly used wedge gate valves form a wedge on the two sealing faces. The wedge angle varies with the valve parameters, typically 5 °. Wedge gate valve gate can be made as a whole, called the rigid gate; can also be made to produce a small amount of deformation of the gate, to improve its technology to make up for sealing surface angle in the process of deviation, this gate The board is called a flexible gate. Gate valve is closed, the sealing surface can only rely on medium pressure to seal, that is, rely on media pressure to the sealing surface of the gate pressure to the other side of the valve seat to ensure that the sealing surface of the seal, which is self-sealing. Most of the gate valve is forced seal, that is, when the valve is closed, it must rely on external force to force the gate to the valve seat to ensure the sealing surface of the seal. Gate valve has the following advantages: 1. Fluid resistance is small, the sealing surface by erosion and erosion of small media. 2. Open and close more effort. 3. The medium flow is unrestricted, does not disturb the flow, does not reduce the pressure. 4. Simple body, short structure length, good manufacturability and wide range of application. Nominal pressure or pressure level: PN1.0-16.0MPa, ANSI CLASS 150-300LB, JIS10-20K Nominal diameter or diameter: DN10 ~ 1000, NPS 1/2 ~ 36 "Connection: flange, butt welding, thread, etc. Applicable temperature: -196 ℃ ~ 700 ℃ Driving mode: manual, bevel gear, pneumatic, electric, hydraulic, gas-liquid linkage, electro-hydraulic linkage Valve body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 ), CF8M (316), CF3M (316L), Ti. Choose different materials, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media.
