Description
Technical Field
The invention belongs to the technical field of check valve control, and particularly relates to a spherical one-way check valve.
Background
The check valve is a valve with a circular valve clack and acts by self weight and medium pressure to block the medium from flowing backwards. It belongs to the automatic valve category, also called check valve, reflux valve or isolation valve. The valve clack motion mode is divided into lifting type and swing type. The lift check valve is similar in structure to the stop valve and only lacks a valve rod that drives the valve flap. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). The valve is opened when the inlet pressure is greater than the sum of the weight of the flap and its flow resistance. Otherwise, the valve is closed when the medium flows backwards. Swing check valves have a flap that is tilted and can pivot, and operate on a similar principle to lift check valves. The check valve is commonly used as a bottom valve of a water pumping device and can prevent the backflow of water. The check valve and the stop valve are combined for use, and the safety isolation effect can be achieved. The disadvantages are high resistance and poor sealing performance when closed.
