Dynamic constant-pressure constant-flow regulating valve

A dynamic regulating valve CVCC, to a regulating valve comprising a valve body, a throttle ball, the spring, the spring displacement adjusting mechanism and the chamber support structure equipped with a valve body cavity, open at both ends, respectively, of the valve body a water inlet and a water outlet, the ball intermediate throttle opening has a through hole, one end of the spring means by adjusting the displacement of the spring is fixed to the valve body, the ball and the other end is fixedly connected with the throttle, the cross-sectional area of ​​the cavity gradually toward both ends by the intermediate becomes smaller, the minimum cross-sectional diameter is greater than the diameter of the orifice of the sphere; cavity support structure comprises a ball end support bar, two fixing rods, fixing bars are fixed to the body cavity, and the other end slidably supporting hole is opened, a sphere One end of the support rod slidably mounted in a support hole near the water outlet, the other end passes through the through hole, the spring is connected to the rack. According to the present invention can dynamically adjust the water flow pressure to achieve the water-saving effect, extend the life of the faucet has a simple structure, etc., to promote the use convenience.
