Inlet check valve check valve principle of the check valve check valve features standard check valve check valve size check valve price Check valve also known as a one-way valve or check valve, and its role is to prevent the media back in the pipeline. Pump water off the bottom valve check valve also belongs to class. Opening and closing pieces by medium flow and the forces to open or close, backflow valve to prevent the media called the check valve. Check valves are automatic valves, mainly for one-way flow of media channels, only allowing media to flow in one direction, to prevent accidents. Check valve according to the structure of division, can be divided into the lift check valve, swing check valve and butterfly valve three. Lift check valve can be divided into vertical and horizontal two. Swing check valve is divided into a single type, double valve and valve type three. Butterfly valve for the straight through, the above non-return valve can be divided into connection, flange and welding of three thread in the connection form. Check valve should be installed in the top note of the following things: 1, in the pipeline not to bear the weight of the check valve, a large check valve should be independent of support, so that due to piping pressure. 2, the installation media attention to the direction of flow should be consistent with the body of the votes in the direction of the arrow. 3, the vertical lift check valve should be installed in a vertical pipe. 4, the level of valve lift check valve should be installed in horizontal pipe.
