Water-saving valve

Abstract

The invention discloses a water-saving valve which is installed in a water tank of a squatting pan, feeds water into the water tank and pushes the water flow flowing from the water tank of the squatting pan into a bed pan. The water-saving valve comprises a water inlet pipe, a main valve, an antisiphon valve, an auxiliary valve, an injection pipe and a water outlet, wherein the water inlet pipe is connected with an external water source; the main valve is communicated with the water inlet pipe; the antisiphon valve is communicated with the main valve; the auxiliary valve is communicated with the antisiphon valve; the injection pipe is communicated with the auxiliary valve; the water outlet is used for discharging water into the water tank; the auxiliary valve controls water injection to the middle part or the bottom part of the bed pan or the bottom part of a sewage discharging pipeline inlet; and the main valve controls water feeding to the water tank of the bed pan and the opening of the auxiliary valve. In the water-saving valve, the water pressure of the external water source is utilized for pushing water flow discharged from the water tank to wash, so that the problem of large water using amount is effectively solved; and the water using amount is less, the installation is simple and convenient and the cost is low.

Description

technical field [0001] The invention relates to a water-saving valve, in particular to a water-saving valve installed in a toilet water tank. Background technique [0002] Existing closets generally only rely on the water discharged from the water tank to flush the bedpan. Although there are spray holes at the bottom of the bedpan, the water sprayed from the spray holes also comes from the water tank. Due to the limited height of the water tank, the water coming out of the water tank The water pressure is very low, and more water is needed to flush the bedpan; some toilets are completely flushed with pressure water such as tap water, but the water pressure is relatively high, requiring a pressure of more than 300KPa, otherwise it is difficult to flush clean, and flushing Sometimes there will be a loud noise. [0003] Existing water inlet valves that feed water into the water tank of the toilet generally only have a water inlet pipe connected to an external water source and ...
