Product Description
Product Introduction
The opening and closing parts of the check valve are opened or closed by the medium flow and power to prevent the medium from flowing back. Check valves are generally divided into four types: lifting, swing, butterfly and horizontal. The general lifting check valve should be installed on horizontal pipelines. The vertical lifting check valve and bottom valve should be installed on vertical pipelines, and the medium flows from bottom to top. The installation position of swing check valve is not limited. It is usually installed on horizontal pipelines, but it can also be installed on vertical pipelines or dumping pipelines. Note: the check valve only allows the medium to flow in a direction, should pay special attention to the medium flow direction, should make the medium normal flow direction and the arrow direction indicated on the valve body, otherwise it will cut off the normal flow of the medium.
H12W vertical screw thread check valve due to the pressure of the medium at the inlet end of the pipeline, and overcome the spring resistance to open or close the valve; When the medium pressure at the inlet end is lower than the outlet end, the spring pushes the valve core to the valve seat to close the valve, preventing the medium from flowing back, so it starts and stops. Vertical check valve is widely used in chemical, liquefied petroleum gas, fluid and other industries.
