Spherical Check Valve
Introduction:
Spherical check valve is a multi-ball, multi-channel, multi-conical backflow structure of the check valve, mainly by the front and rear body, rubber ball, cone body, etc., the disc is rubber coated ball, so it is called a spherical check valve.
Working Principle:
The working principle of the spherical check valve is mainly to realize the opening and closing of the valve by making a short stroke rolling in the ball cover. When the water pump is started, the water will flush the rubber ball under the action of pressure, so that the rubber ball rolls to the right side. The conical body in the valve body after oil is fixed and the check valve is opened; After the pump stops, due to the return water pressure in the piping system, the rubber ball is forced to roll to the left front valve body to achieve the closing of the check valve.
Application:
The spherical check valve belongs to the check valve, which is a kind of check device with multi-demand, multi-channel and multi-conical inverted fluid structure. It is used to prevent the reverse flow of the medium in the pipeline in pharmaceutical, food, chemical, metallurgy and other industries, and can protect the operation of the equipment. The spherical check valve has the advantages of simple structure, the ball is not easy to be stuck in the ball track, and good sealing reliability.
