Check valve structure and installation

Check valve structure: Check valve (One-way valve) According to the structure, can be divided into lifting check valve, swing check valve and butterfly check valve three. Lift check valve can be divided into vertical and horizontal two. Swing check valve is divided into single-valve, double-valve and multi-valve three. Butterfly check valve is straight-through, the above types of check valve in the connection form can be divided into thread connection, flange connection and welding three. Check valve installation should pay attention to the following matters: 1, do not make the check valve in the pipeline to bear the weight of large check valve should be independent support, so that the impact of pressure from the pipe system. 2, when installing, pay attention to the direction of the flow of the medium should be consistent with the arrow direction of the body ticket. 3, vertical drop-check valve should be installed in the vertical pipe. 4, lift-level flap check valve should be installed on the level of the pipeline.
