Multi-stage pressure pilot drain valve

Abstract

The invention discloses a multistage pressure guide drainage valve which comprises a button body, a large drainage button, a small drainage button, a small drainage floater, a small drainage sliding rod, a small drainage positioning tooth, a small drainage button clamp, a button main shaft, a large drainage sliding rod, a large drainage floater, a large drainage button clamp, a large drainage positioning tooth, a sealing sheet and the like, wherein the floaters for controlling large drainage water consumption and small drainage water consumption can be used for freely regulating height on respective sliding rods for controlling the water consumptions. According to the invention, the problems of finely regulating the water storage height by the large drainage fixed floater of the traditional drainage valve according to the size of a water inlet and being incapable of controlling large drainage quantity because too much water is filled in the traditional water tank are overcome so that the water pressure advantage of the height of the water tank is fully developed, therefore, purposes of vigorous washing, clean replacing and water saving are fully realized.

Description

technical field [0001] The invention relates to a valve, in particular to a multi-stage pressure guiding and draining valve used in a water tank of a sanitary ware which can fully utilize the potential energy of water pressure to wash and replace the bedpan. Background technique [0002] Water conservation is really important for human beings. According to statistics from authoritative departments, about 1.5 billion people in more than 80 countries around the world lack clean drinking water, and 450 million people in 29 countries live in a state of water shortage. At present, my country is seriously short of water resources, and the per capita water resources are only a quarter of the world average. [0003] How can sanitary ware save water? For hundreds of years, people have thought of many ways. Regarding the water consumption requirements of sanitary ware, many developed countries have mandatory standards. [0004] In fact, the profound meaning of water saving for sani...

AI Technical Summary

Problems solved by technology

One of the most critical problems is that people have not realized that to clean the sanitary ware, the pressure of the existing water level must be fully utilized; moreover, they have not realized how to use the water level pressure difference in the water tank and the corresponding preparation of the drain valve

Of course, without the advent of the pressure-guided bedpan, there is no place for the pressure-guided water key
