Manufacturer silence check valve

Ball check valve is a kind of multi-ball, multi-channel, multi-cone type inverted fluid structure of the check valve, mainly by the front and back valve body, rubber ball, cone body and so on.

Its working principle is: the rubber ball in the ball cover for short stroke rolling to achieve the valve opening and closing. When the water pump starts, the water under the action of pressure flushes the rubber ball, so that the rubber ball rolls to the right side, the position is fixed by the conical body in the back valve body, 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 close the check cap. The rubber ball is made of hollow steel ball, which is attached with good elastic rubber to ensure sealing and reduce the damage to the pipeline system in the process of valve closing. The cone body with holes has a fixed effect on the steel ball when the valve is opened and eliminates the pressure of the contact area between the rubber ball and the cone body, so that the contact is surface contact and reduces the hydraulic loss caused by the shaking of the rubber ball in the valve body.
