Product Description

First, product introduction
Micro resistance spherical check valve, using rubber covered ball as the valve disc, under the action of the medium, can be rolled on the slide in the valve replacement, so as to open or close the valve. The flow resistance loss is small, the sealing performance is good, the sound is muffled and the water shock wave can be reduced. Horizontal or vertical installation can be. Can be used for cold water, hot water, industrial and domestic sewage pipe network pump outlet, to prevent the backflow of the medium.


Second, the working principle
The disc of the ball check valve is a sphere covered with rubber or engineering plastic, so its sealing is reliable. Ball type check valve nominal diameter size, there are single ball and multi-ball points, the sealing principle is: when the pump, the medium forward flow of the medium pressure to promote the ball movement, along the guide column to leave the seat sealing surface, the check valve will open, the medium through, when the pump is stopped, the medium reverse flow pressure to push the ball along the guide column to roll to the seat sealing surface, close the check valve, By the pressure of the working medium, the ball valve disc and the seat sealing surface produce a certain specific pressure of sealing, to ensure the sealing of the check valve, to prevent the purpose of the medium counterflow.
