Two-stage control high-efficiency water-saving valve

Abstract

The invention discloses a high-efficiency water-saving valve with two-stage control. The working device is a conical water pipe (1), a conical water plug (2), and a rubber spring with variable stiffness (3). The control device is a water plug pull rope (5 ), foot pedal (6), reset rubber spring (7), auxiliary device is water valve bottom cover (4), positioning collar (8), heel shaft (9), ground pit (12), the right side of the valve It is water inlet (10), and the left side is water outlet (11). The present invention designs a two-stage control high-efficiency water-saving valve. First, it can avoid the second pollution of human hands. When washing and washing, it is not necessary to control the valve with hands, but to control the water outlet and stop water through the control device with feet; second, it can efficiently save water. Water, people can save up to 30‑50% of water when washing their hands or face with detergent; the third is to meet individual water needs, either large flow of water or small flow of water, both Water can be used for a short time or for a long time.

Description

technical field [0001] The invention relates to water supply equipment, in particular to civil water supply equipment—that is, a two-stage control high-efficiency water-saving valve. Background technique [0002] At present, in civil water supply equipment, the valves of faucets are mostly manual valves and induction valves. What people often see when washing their face is such a scene: open the valve by hand to receive the water outflow, and the water will still flow out when washing the face by hand; while the sensor valve is based on the pre-designed program to discharge and stop the water, which cannot adapt to everyone's needs. Need water and stop water, thus will produce a large amount of waste of water, or can not meet individual needs. Contents of the invention [0003] The invention overcomes the disadvantages of waste of water in the original device and inability to meet individual needs, and provides a two-stage control high-efficiency water-saving valve. First...
