Delayed-closure single-control linked water-air four-way valve

Abstract

The invention provides a delayed-closure single-control linked water-air four-way valve and aims to implement water saving and emission reduction for toilet flushing in large dormitory buildings, to supplement the water pressure insufficiency with high-pressure air through an air compressor which compresses the air, accordingly to increase excrement flushing pressure to achieve water saving and emission reduction, and to overcome the defect that dirt residue in a toilet deposits over a long period and makes use uncomfortable. The delayed-closure single-control linked water-air four-way valve for use with a water-saving squatting pan comprises a linked press plate having guiding and positioning functions and meeting ergonomic characteristics, two spool components, two stem components, a valve body, two vent pipe orifices and two water pipe orifices. The delayed-closure single-control linked water-air four-way valve with a water-air network system allows water saving and emission reduction to be effectively implemented for the squatting pan, and flushing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of toilet flushing systems, in particular to a time-delayed closing four-way valve for flushing that is matched with a squatting pan. Background technique [0002] Statistics show that my country suffers from a water shortage of about 46 billion cubic meters every year, and 80 million rural people have difficulty drinking water. Among the 517 cities in the country, more than 300 cities are short of water. Against the background of the importance of water resources and China's water shortage situation, the cost of water and sewage treatment is increasing day by day. How to save water and reduce emissions has become a worldwide topic. [0003] Flushing the toilet after defecation is related to everyone's daily life. According to statistics, at present, squatting toilets in my country flush away 9 billion cubic meters of water every year, which is equivalent to the water volume of nine West Lakes and two Taihu...

AI Technical Summary

Problems solved by technology

The toilet water is concentrated during the peak hours, and the water supply pressure is high, which often leads to insufficient water pressure; in addition, in actual use, due to the widespread use of cheap ceramic squatting toilets in the construction of large-scale dormitories, the water pressure is insufficient and cannot be flushed at one time. Repeated flushing not only wastes time, but also increases the cumulative water consumption, and the residual sewage accumulates in the cheap urinals. In addition, the urinals in the dormitory are public facilities, and the mobility of personnel makes the urinals dirty after a long period of time, which seriously reduces Improve the comfort of squatting toilet
