Dynamic constant-pressure constant-flow regulating valve

Abstract

The invention discloses a dynamic constant-pressure constant-flow regulating valve and relates to a regulating valve. The dynamic constant-pressure constant-flow regulating valve comprises a valve body, a throttling ball body, a spring, a spring displacement regulating mechanism and a cavity supporting structure, wherein a cavity is arranged in the valve body, both ends of the valve body are respectively provided with a water inlet and a water outlet, a through hole is arranged in the middle of the throttling ball body, one end of the spring is fixed on the valve body through the spring displacement regulating mechanism, the other end of the spring is fixedly connected with the throttling ball body, the sectional area of the cavity is gradually reduced from the middle part to two ends, and the diameter of the minimum sectional area is larger than the diameter of the throttling ball body; and the cavity supporting structure comprises a ball body support rod and two fixed rods, wherein one ends of the fixed rods are respectively fixed in the cavity of the valve body, the other ends are provided with sliding support holes, one end of the ball body support rod is arranged in the sliding support hole close to the water outlet, and the other end of the ball body support rod sequentially penetrates through the through hole, the spring and a rack. According to the invention, water outflow can be regulated dynamically according to water pressure so as to achieve the effect of water saving, the service life of a faucet can be prolonged, and the dynamic constant-pressure constant-flow regulating valve has the characteristic of simple structure, and is easy to use and popularize.

Description

technical field [0001] The invention relates to a regulating valve, in particular to a dynamic constant pressure and constant current regulating valve. Background technique [0002] For the urban water supply system, the daily water supply fluctuates greatly with the changes of each time period. Generally, the water demand in the morning, noon and evening peak hours is relatively large, and the water demand in other periods is greatly reduced. Today The faucets commonly used by people generally do not have a device to automatically adjust the water output according to the water pressure of the pipe network. When the faucet is turned to the same position, the water output is large when the pipe network pressure is high, and the water output is small when the pipe network pressure is low. When the water consumption does not need to be so large, the current practice is to artificially adjust the opening of the faucet to adjust the water output. In many public places, people gen...

When the water consumption does not need to be so large, the current practice is to artificially adjust the opening of the faucet to adjust the water output. In many public places, people generally do not adjust the opening of the faucet according to their own water demand. would cause a lot of waste
