Check Valve Different Forms Of Butterfly Valve

Kaitai Valve Group Co.,Ltd | Updated: Aug 14, 2017

     Check valve refers to the flow of the media itself and automatically open, close the disc, used to prevent the backflow of the valve, also known as the reverse valve, check valves, countercurrent valve, and back pressure valve. Check valve belongs to an automatic valve, its main role is to prevent the media backflow, to prevent the pump and drive motor reversal, as well as the container media release.Butterfly Valve
     Check valve According to the structure, can be divided into lift check valve, swing check valve and butterfly check valve three kinds: 1. The lift check valve is divided into vertical and horizontal two kinds. 2. Swing check valve is divided into single, double and multiple three kinds. 3. Butterfly Check valve is straight-through. The above several check valve in the connection form may divide into the threaded connection, the flange connection, the welding connection and the clamp connection four kinds. Check Valve: According to the structure of the division, can be divided into lift check valve, swing check valve and butterfly check valve three kinds. Lift check valve can be divided into vertical and straight-through two types. Swing check valve is divided into single, double and multiple three kinds of type.Butterfly Valve
     Butterfly check valve is divided into butterfly-type double, butterfly-type single, the above several check valves in the form of connection can be divided into threaded connection, flange connection, welding and clamp-type connection four kinds.Butterfly Valve
    The disc of the swing check valve rotates on the rotating shaft. Its fluid resistance is generally smaller than the lift type check valve, which is suitable for large caliber occasions. Swing Check Valve According to the number of disc can be divided into single disc swing type, double disc swing type and multiple-disc swing three kinds. Single-disc swing check valves are generally suitable for medium caliber occasions. In order to reduce water hammer pressure, it is best to adopt a closed check valve which can reduce the pressure of water hammer when selecting single disc swing check valve in large diameter pipe. Double-flap Swing check valve is suitable for Judachon caliber pipe. The pair of double disc swing check valve has small structure and light weight, and it is a fast developing check valve. Multi-disc Swing check valve is suitable for large diameter pipeline.Butterfly Valve
   Ball type Sewage Check valve: The valve body adopts the whole channel structure, which has the advantages of large flow and small resistance. Use the ball to make the disc, apply to high viscosity, have suspended the industrial and domestic sewage pipe network return valve: Check valve (one-way valve): Also known as a valve or check valve, its role is to prevent the flow of media in the pipeline back. The bottom valve of the pump suction pipe also belongs to the check valve class. Can be divided into lift type check valve, swing check valve and butterfly check valve three kinds. Lift check valve can be divided into vertical check valve and horizontal check valve two kinds. The Swing check valve is divided into three kinds: single check valve, double flap check valve and multiple-valve check valve. Butterfly check Valve for the straight-through check valve, the above several check valve in the form of connection can be divided into threaded connection check valve, flange connection check valve and welding check valve three kinds.Butterfly Valve
