TIANSHUN VALVE
The vertical check valve works by overcoming the resistance of the spring through the medium pressure at the inlet of the pipe to open or close the valve. Specifically, when the medium flows downstream, the valve is opened by the thrust of the medium; When the flow direction of the medium is reversed, that is, when the pressure of the medium at the inlet is lower than the pressure at the outlet, the spring pushes the spool to the seat, so that the valve is closed and the medium is prevented from flowing back.
Swing check valve is an important fluid control valve, which is mainly used to prevent the backflow of media in the pipeline. The working principle of the swing check valve is that when the pipeline fluid flows in the specified direction, the disc inlet pressure is higher than the outlet pressure, the disc is pushed away from the seat, and the valve is open. When the pressure difference between the two sides of the valve disc decreases to a certain level, the valve disc falls and returns to the closed state, preventing the backflow of the medium.
A double-plate check valve is a valve consisting of two movable plates connected by a spring. This valve allows the medium to flow freely in one direction, and when the medium tries to flow in the opposite direction, the double plate will quickly close under the action of the spring to prevent backflow. It is mainly composed of valve body, valve cover, valve disc (two movable plates), spring, seat and other components.
Founded in 1993, after 19 years of development, it has become one of the large valve manufacturing bases in Tianjin, China....
