A water-saving water valve with throttling and flow-limiting structure and its processing technology

Abstract

The invention discloses a water-saving water valve with a throttling and flow-limiting structure and its processing technology, which belongs to the technical field of water-saving water valves and includes a valve housing and a water inlet pipe. The water inlet pipe runs through the side of the valve housing and communicates with the inside. A sealing device, a lifting device and a rotating device are respectively installed inside the housing. The sealing device separates the inner cavity of the valve housing, and the sealing device is placed outside the lifting device. The bottom end of the lifting device connects with the rotating device extending to the valve housing. When you need to use it, pull down the hand rest, the spring will be stretched, and the liquid will flow out of the hand rest through the water flow channel, which not only cleans your hands but also cleans the surface of the hand rest, improving the sanitation effect. After you let go, the spring pulls the valve core to rise as a whole. The upper sealing block rises synchronously, and the outlet of the water flow channel is blocked against the inner wall of the valve housing, so as to ensure that the valve core will not drop, and the water flow will not flow out from the hand rest. Through two sealing actions, the internal pressure of the water valve will be improved. Sealing, so as to achieve the purpose of throttling and limiting.

Description

A water-saving water valve with throttling and current-limiting structure and its processing technology technical field The present invention relates to the technical field of water-saving water valves, in particular to a water-saving water valve with throttling and flow-limiting structures and its processing technology. Background technique The water valve of traditional mechanical control, the control switch is all arranged on the top or side of the whole casing, although the control is convenient, However, there is a problem when it is used in public places: after washing your hands, you need to manually close the water valve. There is no guarantee of cleanliness, so it may cause cross-infection. Especially in some high-end public places, after washing Touching the switch handle again is always uncomfortable. However, it is difficult to set the traditional water valve switch at the water outlet, and some people have mentioned It is possible to install the exis...

Problems solved by technology

[0002] For traditional mechanically controlled water valves, the control switches are all set on the top or side of the entire housing. Although the control is convenient, there is a problem when used in public places: the water valve needs to be manually closed after washing hands. There is no guarantee of cleanliness, so there may be cross-infection

Especially in some high-end public places, it is always uncomfortable to touch the switch handle after washing

However, it is difficult to install the traditional water valve switch at the water outlet. Some people also propose to install the existing water valve upside down, so that when the water valve is finally closed, the water flow keeps flowing through the water valve switch handle, but this installation The water flow flows out of the nozzle from bottom to top, the water flow is not easy to control, it is inconvenient to wash hands, and it will cause waste of water, so this method is basically not feasible
