Abstract

The utility model relates to a water saving control valve for toilet cistern which is a water saving and multi-stage control valve. The utility model is composed of a pull rope, a valve cap, shafts, a valve seat, an overflow proof pipe, and fixing nuts and pads. The utility model is characterized in that the valve cap is made of rubber, one fixed arm or two fixed arms are arranged on the valve cap, and the valve cap is fixed on the overflow proof pipe or the valve seat by one shaft or two shafts. The valve cap can rotate around the shaft 0-80 DEG, and has the advantages of convenient pulling, accurate opening and closing, good sealing effect, and high durability. The water saving control valve for toilet cistern has the advantages of simple structure, and low cost, and the cost is 50% lower than the cost of other water saving valve. The utility model is suitable for the installation of a high level cistern and a low level cistern in a toilet of an apartment building.

Description

Water saving control valve for toilet cistern

A kind of control valve that relates to the water closet draining is the water saving multilevel control valve, is applicable to the installation of family dependents' building and communal bathroom higher/lower cistern.

The draining control valve of lavatory higher/lower cistern roughly can divide three classes at present: the one, and hydrocone type, the 2nd, floatation type, this two class all is to draw, water tank water is promptly once arranged light, the 3rd, the patent No. 88211227.9 discloses a kind of water closet water saving flushing valve, form by valve seat, sewer pipe, hold-down nut, support, valve rod, nut, water saving plug, suspension hook, pull bar, stay cord, when pull-up water saving plug, water flows directly into sewer pipe, looses one's grip and closes immediately when one.To realize control flowing water.This valve arrangement complexity, the cost height has guiding mechanism, needs pulling force big.

The purpose of this utility model provides a kind of simple in structure, lifts light and handy convenience, the water saving control valve that lavatory high-level or low-level water case all is suitable for.

The utility model is achieved in that and changes existing water saving plug into the counterweight rubber valve gap, Yi Bian 1-2 fixed arm arranged, is fixed on anti-overflow pipe or the valve seat by 1-2 axle, on the extended line of fixed arm center and the valve gap center of circle straight line stay cord bolt is arranged.

The utility model is compared with existing water saving control valve: saved parts such as connecting rod, nut, guide securement frame, simple in structure, cheap, it is about 50% to reduce investment outlay, and valve gap is swung essentially no friction around axle, lift light, open accurately, adopt the counterweight rubber lid, good sealing effect, stopped the seepage phenomenon, can be widely used in family dependents' building public lavatory high-level or low-level water case and install.Can save flushing water more than 70% than hydrocone type, floatation type.

Be described further below in conjunction with accompanying drawing:

Fig. 1 is a water closet water saving control valve structural representation (opening)

Fig. 2 is the valve gap part drawing

Water tank is by lever handle or remove (1), a floater controlled valve (2), noiseless water inlet pipe (3), water tank shell (4) are formed among the figure.The water saving control valve is made up of stay cord (5), valve gap (6), valve seat (7), hold-down nut and pad (8), valve gap fixed axis (9), anti-overflow pipe (10).Stay cord (5) adopts nylon or fiber stranded rope, and valve gap (6) adopts elastomeric material, and remaining parts all adopts plastics to make.Valve gap (6) can be made into spill, convex or plate shaped, its external diameter is greater than valve seat (7) 6-8mm, thick is 2-3mm, 1-2 fixed arm (11) arranged on one side, be fixed on the anti-overflow pipe (10) by 1-2 axle (9), also can be fixed on the valve seat (7), valve gap (6) can rotate 0-80 ° of angle around axle (9), on the extended line of the center of circle straight line of fixed arm (11) central point and valve gap (6), stay cord bolt (13) is arranged, stay cord (5) with regard to bolt in the above, valve gap (6) is opened by pulling force, falls by deadweight, by deadweight and negative-pressure sealing, so require valve gap (6) deadweight 15-30 gram, if less than 15 grams should increase counterweight (12) at the valve gap circle centre position.Have anti-overflow pipe (10) on the valve seat (7), it is bonding with valve seat (7) or is threaded.
