Lift check valve

Lift check valve

For the check valve with the disc sliding along the vertical center line of the valve body, the lift check valve can only be installed on the horizontal pipeline. For the high pressure small diameter check valve, the disc can be a ball. The body shape of the lift check valve is the same as that of the stop valve, so its fluid resistance coefficient is larger. Its structure is similar to the stop valve, and the valve body and disc are the same as the stop valve. The upper part of the valve disc and the lower part of the valve cover are provided with guide sleeve. The guide sleeve of the valve disc can rise and fall freely in the guide sleeve of the valve cup. When the medium flows downstream, the valve disc will open by the medium thrust. When the medium stops flowing, the valve disc will fall on the valve seat by itself to prevent the medium from flowing backward. The direction of medium inlet and outlet channel of straight through lift check valve is perpendicular to the direction of valve seat channel; The flow resistance of vertical lift check valve is smaller than that of straight through check valve.
