Sleeve plug valve is a kind of precise fluid control equipment, its clever design lies in the sleeve connection between the plug and the valve body. This structure not only ensures excellent sealing performance in high-pressure environments, but also facilitates installation and maintenance. Sleeve plug valve for its reliable cut-off capacity and smooth media flow characteristics. It is mainly used for oil and gas storage and transportation in chemical industry, metallurgy, paper making, food processing and other industries, for opening or closing, and with pneumatic and electrical devices can also achieve remote operation to ensure personal safety.
When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
The Comodity Cast Steel Gate Valve is mainly composed of valve body, valve cover, valve wedge, valve seat and valve stem. The two sealing surfaces are wedge-shaped gate valves. The purpose of the wedge is to improve the auxiliary seal load, to achieve both high medium pressure sealing and low medium pressure sealing. The valve body of the wedge valve is provided with a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
