Vertical check 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.
