Description

Water Saving low level cistern parts

The water-saving lower water box accessory of the utility model belongs to sanitaryware.

Tank for excrement pan is the domestic water capital equipment, and old-fashioned cistern fittings design is very unreasonable, has serious seepy question, has become the water resource waste public hazards, and causes that relevant government department payes attention to.About cistern fittings multinomial patent application is arranged in recent years, wherein Chinese patent 86202844,86207256,86206174 all discloses the cistern fittings new construction that has improved.Particularly the patent No. is 87214589 to be the improvement again on patent 86206406 bases, the technology comparative maturity, scheme is more reasonable than the former, prolong the control room water inlet and chewed height, outer wall is with anti counter-flowing flat rubber sheet, draining valve has down the board-like water shutoff flap valve of bowl bodies and wedge-shaped slot, and drainage switch is equipped with sucker and sucker delayer.Though this improvement design designs simplification is convenient to the classification flushing, flushing dose also can be regulated arbitrarily, and water still enters from a water tank high position, and ball float floats with water level, exists noise big, the fragile deficiency that waits of control wet part.

The purpose of this utility model is to change above-mentioned prior art control water principle, adopts spiral water outlet, utilizes pressure reduction and elasticity water inlet control valve, improves the control water section, forms a kind of excrements and can divide retaining flushing, the water-saving lower water box accessory of low noise.

Following mode better realizes above-mentioned purpose:

The utility model is the accessory that is installed in the lower water box.Its composition comprises into water and draining two parts, and wherein water inlet portion is made up of fixed part and moving part, and the water part is made up of valve body and control assembly thereof.It is characterized in that the interior pipe 24 that is fixed in the water tank inlet place is connected to form spiral inlet channel with outer tube 23 by screw-button, form the water inlet die cavity between core pipe 26 upper boss and the rubber cushion 22, jog and holder 21 form the intake pressure chamber in the middle of the rubber cushion 22.There is a contraction section 27 at the place in the middle of the valve rod, and contraction section 27 arrives the cylinder axis of valve rod 18 tips to uniform several shallow grooves 28.Its feature also is to discharge water partly the discharging valve 2 of two highly different band valve gaps, and valve gap and escapement 6 are flexible coupling, and escapement 6 can make the valve gap of one of discharging valve open respectively along rotating counterclockwise.

Make into water road shape in the shape of a spiral after more than improving, enter water tank bottom between interior pipe and outer tube, reduce and go into water noise, valve rod displacement is short, and disconnected respectively or cut-in pressure chamber is communicated with atmosphere, leans on rubber cushion elastic force keying water route.The action noiseless, rubber cushion is stressed little, and engaging pressure is little, prolongs accessory application life, has avoided the water leakage, and the flushing of excrements stepping can be realized in two dewatering outlets, and the flow that discharges water is big, and scouring force is strong, reaches the water saving purpose.

Below in conjunction with the description of drawings specific embodiments:

Fig. 1 is the location plan of accessory in water tank;

Fig. 2 is the water inlet portion structural representation;

Fig. 3 is that valve rod is at the opening drawing of site;

Fig. 4 is that valve rod is at the closure state drawing of site.

The utility model is divided into water inlet portion and water part.The fixed part of water inlet portion is made up of outer tube 23, interior pipe 24, core pipe 26, holder 21, rubber cushion 22, lid 20, axle 19, nut 9, packing ring 10, ring 12.In pipe 24 be fixed on the water inlet of water tank by nut 9, interior pipe 24, outer tube 23 screw-buttons connect, and form spiral inlet channel.Core pipe 26 is with rubber ring 10 and interior pipe 24 chuckings, core pipe 26 upper boss and rubber cushion 22 are fitted, when drum is gone up at the rubber cushion middle part, form the water inlet die cavity, holder 21 cooperates with outer tube 23 through fixed handle and compresses rubber cushion 22, rubber cushion 22 peripheries and central protuberance part compress with holder, and the medial concavity of rubber cushion 22 has a certain amount of displacement space, can form described pressure die cavity and water inlet die cavity.The moving part of water inlet portion includes float 11, bar 14, arm 13, valve rod 18, spring leaf 15, backstay 14, so that moving up and down, float drives bar 14 and arm 13 motions, when valve rod 18 and the hinge joint of arm 13 other ends, float 11 moved with water level, valve rod 18 go here and there up and down and is moved.There is a contraction section 27 at the place in the middle of the valve rod 18, its external cylindrical surface to the valve rod tip is evenly equipped with axial shallow slot, contraction section 27 length and valve rod 18 distance between two tips are designed to when float 11 rises to the qualification peak level from the limit inferior position, air vent 29 on valve rod 18 contraction sections and the rubber cushion has a certain amount of overlapping, forms between pressure chamber and the atmosphere to be communicated with.When float surpassed the qualification water level, air vent 29 was staggered with valve contraction section 27, occluding pressure chamber and atmosphere path, and the rubber cushion lower surface is stretched out in the valve rod tip, and the water route is communicated with intake antrum through shallow slot 28.When water level is lower than specified altitude, stem position as shown in Figure 4, contraction section 27 coincides with the air vent 29 at rubber cushion 22 intermediate projections places, pressure chamber is communicated with the back decompression with atmosphere, rubber cushion 22 leans on the resilience that makes progress of self elastic force, unlatching intake antrum.On the contrary, when water level to about take the altitude, valve rod 18 is in Fig. 3 position, valve rod shrinks 27 staggered with air vent 29, occluding pressure chamber and atmosphere UNICOM enter pressure chamber through shallow slot 28 water, rubber cushion 22 rebounds downwards, closed intake antrum is blocked current.

The Drainage Division is made up of adjutage 1, two valve gaps 2, bleed off pipe 3, support 4, plug 5, escapement 6, rod 7, release knob 8, nut 9, packing rings 10.Adjutage 1 is fixed in the water tank dewatering outlet, and rod 7 is fixed on release knob 8 and slides in the slotted eye of escapement 6, drives escapement or right swing left, connect escapement and valve gap with tightrope, the selection valve gap is opened, and classification is washed away, and bleed off pipe 3 communicates with the water entering section water outlet by sebific duct 17.

The utility model adopts differential water intaking valve, intakes from water tank bottom through conveyor screw, and the current noise is low, and extraneous hydraulic pressure is big more, and the sealing of water intaking valve is good more; The water valve sensitivity under 0.05MP hydraulic pressure, can be filled with water tank in 120 seconds; Water discharging part is realized the flushing of excrements stepping, and current are anxious, and water supply volume is few; By the gravity valve gap of obturaging, eliminate drainage.
