Abstract

The utility model discloses a pedal, hand pressed water saving spray valve which is suitable for the rinsing of the toilet or other purposes with a water works, in particular to the area of poor water quality. The utility model comprises two parts of a high pressure chamber and a low pressure chamber, adopting a ' through-needle ' automatically reset and clean a discharge hole to make the discharge hole clog difficulty. So the utility model is especially suitable for the area of poor water quality. Because the guiding hole and the aided damper are made into an integration with a valve seat, the utility model has the advantages of very simple structure, easy dismounting, easy inner cleaning, convenient operation, water saving which is over one third than an old water tank, and washing time saving.

Description

Foot-operated, hand is pressed the dual purpose water-saving flushing valve

Foot-operated, the hand that the utility model discloses a kind of big hand urinal flushing that is used for the building lavatory is by the dual purpose water-saving flushing valve, all have the big or small urinal in lavatory in the building of water service can install and use, and is particularly useful for the relatively poor area of water quality.

Prior art in this technical field, by inquiring about relevant intelligence data, the flushing device for toilet that uses in present most lavatory is the flushing device for toilet of old-fashioned cisten mechanism, the water-saving valve of recent design and production adopts earial drainage time-delay conducting principle, its structure is that valve body is divided into high pressure chest and low pressure chamber two parts, when opening the valve flushing, by manually high pressure chest and low pressure chamber being communicated with, at this moment, spool one side, bear water under high pressure pressure, opposite side bears low pressure, and spool compresses support spring, move to low pressure chamber, thereby the valve conducting is opened, and meanwhile, the discharge orifice on the spool begins earial drainage, make the interior hydraulic pressure of high pressure chest from new rising, when spool both sides water pressure during near balance, under the spring force effect, spool again return reach the time-delay closing valve purpose.This water-saving valve has saved old-fashioned cistern system, and can regulate the bath delay time, than old-fashioned flushing device for toilet using water wisely more than 1/3rd.But this water-saving valve is very high to requirements in water quality, require by can not containing graininess impurity in the water of valve, and this class water-saving valve needs often maintenance, and the dismounting difficulty, therefore, this water-saving valve is difficult to apply.

In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of foot-operated, hand by the dual purpose water-saving flushing valve, this foot-operated, hand is pressed the dual purpose water-saving flushing valve, not only can using water wisely, but also eliminated fully owing to water quality inferiority stops up the possibility that discharge orifice causes defective valve.

Foot-operated, dual-use manual water saving flushing valve of the present utility model, its valve body comprises high pressure chest and low pressure chamber two parts, adopt " cleansing pin " the cleaning discharge orifice that automatically resets, be applicable to the area use that water quality is relatively poor fully, the casting pod apertures is an one with helping towards device and valve seat, make the performance of valve more reliable, structure is greatly easy.This foot-operated, dual-use manual water saving flushing valve can be ridden also and can press by hand.Hand on time, it is made up of valve gap, valve pocket, spool, valve seat and axle, when riding, the valve gap of hand is replaced with a convex serum cap.

Description of drawings:

Fig. 1 is the structure chart of the utility model hand.

Fig. 2 is the foot-operated partial structurtes figure of the utility model.

According to Fig. 1, shown in Figure 2, this is foot-operated, hand is pressed the dual purpose water-saving flushing valve, it is by valve seat 1, spring 2, spool 4, valve gap 11(a) or 11(b), valve pocket 6, little axle 9 and sealing ring etc. form, its spool matches with valve pocket 6 by sealing ring 7, one of spring is contained on the flange of little axle 9, the spool inner bottom part is pushed down in the other end is fixed in the valve seat it, valve seat 1 is with valve pocket 6 and valve gap 11 and is threaded, it is characterized in that fixedly cleansing pin 5 of little axle 9 right-hand members, have the flow-guiding channel of casting d to communicate with helping in the valve seat 1 towards device e.When adopting hand on time, by valve seat 1, spring 2, sealing ring 3,8,10,12,13, spool 4, cleansing pin 5, valve pocket 6, y _xRunddichtringO 7, little axle 9, valve gap 11(a) form, valve pocket 6 is connected with valve seat by screw thread, and surrounds high pressure chest a jointly with spool 4 and little axle 9, valve gap 11(a) with valve seat 1 by being threaded, and surround low pressure chamber b jointly with valve pocket 6 outer faces and little axle 9, when valve closing, the sealed circle 8 of high pressure chest a and low pressure chamber b separates, when employing is manually pressed little 9, high pressure chest a is communicated with low pressure chamber b, and the water of high pressure chest a passes through, and circular passage c flows to low pressure chamber b, flow to through honeycomb duct d again then and help towards device e, meanwhile, the pressure in the high pressure chest a reduces rapidly, and spool 4 is moved to the left under the effect of water under high pressure, the valve conducting, after unclamping little axle 9, under the effect of spring 2, little axle 9 resets, again high pressure chest a and low pressure chamber b are separated, because the continuous earial drainage of discharge orifice on the spool 4 slowly raises the hydraulic pressure of high pressure chest a, when near inner pipe water pressure, spool 4 resets under spring action, current is cut off finish once time-delay flushing.Whenever press a little axle 9 once, just clear up discharge orifice once automatically, eliminated fully because water quality inferiority stops up discharge orifice with little axle 9 cleansing pins that link to each other 5, and cause the possibility of defective valve, adopt when riding, save sealing ring 10,12) by valve gap 11(b, valve seat 1, the outer face of valve pocket 6, little axle 9 and convex serum cap 14 surround low pressure chamber b, with foot-operated convex serum cap 14, promote little axle 9, Open valve.

Should be foot-operated, hand press the dual purpose water-saving flushing valve, its valve gap 11(a), valve pocket 6, spool 4 and little axle 9 adopt plastic injection-moulded or the metal machine forms, valve seat adopts grey cast-iron casting or injection molding, valve gap 11(b) the employing elastomeric material makes.

The utlity model has simple and reasonable for structure, easy accessibility, be convenient to the advantages such as maintenance, clean easily inner to get rid of clogging when especially breaking down, serviceability is reliable, and cost is low, and not high to water quality requirement, again can using water wisely, so this valve is applied widely, be easy to promote the use of.
