Check valve: Check valve is also called check valve or check valve, its role is to prevent the backflow of media in the pipeline. The bottom valve of the water pump suction close also belongs to the class of check valve.
The opening and closing parts are automatically opened or closed by the flow and force of the medium to prevent the backflow of the medium. The check valve belongs to the automatic valve class, which is mainly used on the pipeline with one-way flow of the medium, and only allows the medium to flow in one direction to prevent accidents.
According to the structure of the check valve, it can be divided into three kinds: lift check valve, swing check valve and butterfly check valve. Lift check valves can be divided into vertical and horizontal two types. Swing check valves are divided into single disc type, double disc type and multi-disc type. The butterfly check valve is straight-through, and the above check valves can be divided into three kinds of threaded connection, flange connection and welding in the connection form.
Purpose:
Flange connected swing check valve is suitable for nominal pressure PN1.6-16.0MPa, working temperature -29-550℃ petroleum, chemical, pharmaceutical, fertilizer, power industry and other working conditions of the pipeline. Applicable media: water, oil, steam, acid media, etc.
