Description

Water-saving valve for toilet cistern

Technical Field

The invention relates to a water-saving valve of a toilet water tank, in particular to a water-saving valve integrating water inlet and water outlet of the toilet water tank.

Background

The water inlet valve of the toilet tank controls water inlet independently, the water discharge valve controls water discharge independently, namely when the toilet needs to be flushed, the water discharge valve opens the toilet tank to discharge water, and the water inlet valve is used for opening a running water path to replenish water to the toilet tank.

The theory of operation of water intaking valve utilizes the flotation pontoon drive pendulum rod to swing, makes the pendulum rod open or close the pressure release hole in back pressure chamber, if the pressure release hole is stopped up, the pressure in the back pressure intracavity will increase then promote the stagnant water cushion and close the inlet tube by force, if the pressure release hole is opened, then after the pressure in the back pressure intracavity reduces, the water pressure in water route will oneself break away stagnant water cushion, for example the utility model patent of grant notice No. CN2900961Y just discloses such a water intaking valve.

The theory of operation of drain valve is that the delivery port of lifting rod opening water tank is upwards lifted, and the pendulum hook is hung the lifting rod simultaneously and is prevented that the lifting rod from falling down, and when the flotation pontoon of drain valve lost buoyancy because the surface of water descends and fall down the back naturally, the flotation pontoon drives the pendulum hook and takes place the swing, and the lifting rod just falls down with the separation of pendulum hook and recloses the delivery port, for example the utility model patent of grant publication No. CN105421543B has just disclosed such a drain valve.

The water inlet valve and the water outlet valve are respectively controlled by different buoys, and the different buoys are required to be arranged in different water tanks, so that the number of product elements is large, the structure is complex, more space in the toilet water tank is required to be occupied, and the miniaturization of the toilet water tank and the lifting of the water filling amount are not facilitated.
