Water saving valve

Abstract

The invention discloses a water-saving type valve. The water-saving type valve comprises a valve body, wherein a water inlet channel and a water outlet channel are formed in the valve body, one end, far away from the valve body, of a compression spring, is fixedly connected with a pressing block, a compression connection rod and a valve rod are both movably inserted into a sealing part, one end, far away from the pressing block, of the valve rod, is fixedly connected with a washer, the washer is movably matched with a valve component, one end, far away from the pressing block, of the compression connection rod, is fixedly connected with a rack, the rack is meshed with a drive gear, the drive gear is meshed with a driven gear, the pressing block is movably installed in a sleeve, a spring isfixedly installed in the sleeve, and one end, far away from the sleeve, of the spring, is fixedly connected with a compression block. The water-saving type valve can automatically close and open a water valve, can regulate magnitude of water pressure so as to control water outflow amount in unit time, and meanwhile can use up and down movement of the compression block to further regulate water flowing speed, enables a faucet to drain off water in a quick and slow alternate mode, and effectively saves water source.

Description

technical field [0001] The invention relates to the technical field of water valves, in particular to a water-saving valve. Background technique [0002] A water-saving valve with the application number "CN201610627536.5" in the prior art includes a main valve and an auxiliary valve arranged on the valve body from left to right. The main valve includes an operating rod and an elastic plug at the lower end of the operating rod. body, the upper end of the operating rod includes a planar structure and a downwardly inwardly bent arc structure extending from the edge of the planar structure, the lower end of the arc structure is a smooth smooth transition body, and the smooth transition body It is stuck in the annular groove horizontally arranged on the outer wall of the valve in the vertical direction corresponding to the operating rod. There are several annular grooves, and the annular grooves are distributed along the vertical direction on the outer wall of the valve. The auxi...

Problems solved by technology

[0003] Although it solves the problem that the gear of the traditional faucet cannot be adjusted, the above-mentioned water-saving valve still has obvious defects in the use process: 1. It still needs to be closed manually, and it cannot be closed automatically. It is easy to cause water leakage due to the user forgetting to close the valve. Resources are wasted in vain; 2. The reduction of water flow cannot be automatically controlled during use, and the water saving effect is limited
