Product description

Check valve refers to a valve whose opening and closing part is a circular disc and acts by its own weight and medium pressure to block the backflow of the medium. The movement mode of the valve disc is divided into lift type and swing type. The lift check valve is similar in structure to the globe valve, except that it lacks the valve stem that drives the valve disc. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened. Conversely, the valve is closed when the medium flows back. The swing check valve has a disc that is inclined and can rotate around the axis, and the working principle is similar to that of the lift check valve. Follow the thread ball check valve below to see its precautions.
1. Do not allow the check valve to bear the weight in the pipeline system. The large check valve should be supported independently so that it will not be affected by the pressure generated by the pipeline system.
2. When installing, pay attention to the direction of medium flow should be consistent with the direction of the arrow marked on the valve body.
3. The lift-type vertical flap check valve should be installed on the vertical pipeline.
4. The lift-type horizontal flap check valve should be installed on the horizontal pipeline.
The above is the relevant knowledge of thread ball check valve to introduce the precautions of check valve.
