Description

Hydraulic type is ridden water-saving valve

Technical field

The utility model belongs to a kind of running water valve technical field, particularly to the improvement of its structure.

Background technique

Family expenses and traditional hand-wring type valve (the being commonly called as water tap) control of the many employings of public domestic water are gone up by society at present.It is not very convenient to cut-off current with the hand-wring type water tap, often have the people not tighten leading people and leave, or flowing water constantly causes waste during soap, also causes the virus and bacteria cross infection simultaneously easily, especially when disease transmission.Existing foot-operated pipeline valve was once used in some public place, but because of the reliability of its sealing and mechanism all undesirable, event is leaked and is damaged all very serious, influenced using effect, its structure is, spool overcomes spring thrust by pull bar and pulls down during water, valve body and the sealed faying face and the pad of spool is separated, thereby make the valve open water flowing; During water, spool does not rebound by spring and recovers to compress sealing state, thereby blocks the water source.When as installed was used, the pulling of pull bar realized by pedal lever.There is following problem in this valve, and 1 sealing is unreliable.The main realization that compresses that relies on the rubbery flat gasket sheet of sealing.This pad life-span is short, generally has only half a year, seriously becomes vital wound so the class valve leaks.The also easy stuck akinesia of pull bar.2 mechanism's complexity are installed inconvenience.Pedal lever is made up of channel-section steel, angle bar, hinge, pedal etc., and structure is scattered, and member is coarse, and trouble is installed.3 inconvenient maintenance.In addition, also have a nearly period and adopt inductive water tap, though its using effect is good, price is more expensive, and every cover price nearly 1,000 yuan is not that ordinary consumer afford to can bear.Particularly large size is used or is transformed, and in fact is difficult to promote.This in addition device is wanted electricity consumption, has increased trouble and the power consumption installed.Electricity mixes with water simultaneously; Increased the possibility of fault.

Summary of the invention

The problem that the utility model exists at the said goods just and provide a kind of improved hydraulic type to ride water-saving valve.Hydraulic type is ridden water-saving valve, and the pump housing 1 and valve body 21 have water intake and water outlet on the valve body; It is characterized in that spool 19 tops of body cavity are cone, its external stability has seal ring 20, and the cone of spool is tightly connected by the internal conical surface of seal ring 20 with valve body 21; The spool middle part has a circle groove, forms cavity 24 with valve interior wall, is communicated with water outlet; Center spool has pod apertures 22, and pod apertures one end is communicated with the connecting tube 9 of the pump housing 1, and the other end is communicated with the water intake of valve body; The end that pod apertures is opposite with spool cone end is inverted cone; Valve plug 12 is fixed on the top of valve body by seal ring 13, withstands on the spool by stage clip 14; Inner spool 16 is positioned at pod apertures inverted cone one end, is fixed with seal ring 15 on it; Pod apertures inverted cone one port is fixed with spacing back-up ring 17, the displacement of restriction inner spool 16.

Spool 19 bottoms are fixed with at least one circle seal ring 18.

The pump housing 1 has center hole, and center hole is communicated with water outlet 23; The pump housing is fixedlyed connected with pump cover 2; Pump cover has the center hole coaxial with the pump housing, and pump core 4 passes center hole by seal ring 6, the fixedly connected foot treadle 3 of an end, the other end fixed connection and sealing circle 11; Pump core middle part has the convex shoulder, so that the displacement of restrictive pump core.

The other end of pump core 4 is fixed with bowl ring 10.Other seal rings can be " O " RunddichtringO.

The intake-outlet 23 of the pump housing is communicated with connecting tube 9.

Working principle of the present utility model is, (pressure is greater than 0.1kg/cm when water intake and water source ²) when connecting, spool is pressed to the below by stage clip, the conical surface seal ring on it and the conical surface driving fit of valve body form reliable sealing, and the prevention current are from the water outlet discharge and make valve be " pass " state.The pod apertures in the spool simultaneously, its lower end be by an one-way valve of being made up of inner spool, only allows water to be downward through and can not reverse flow.The water that flows to the below flows to foot pump by connecting tube, till being full of.When installing first, the water that attracts from the water-saving valve body can not flow foot pump, and available pulling moved the pump core for several times, and air can drain in the pump, and water just is full of wherein.This moment as more slightly with defeating or step on the pump core, just the water that the pump core is extruded is compressed into water-saving valve by connecting tube.Because the effect of one-way valve, water can not flow through pod apertures, can only make spool overcome stage clip pressure and push it against the top and open valve and make it to be " opening " state.If unclamp the pump core, then stage clip is depressed spool again, and the pump core lifts again, and water-saving valve is " pass " state again.

The utility model has the advantages that 1 sealing is reliable.Valve body and spool adopt the conical surface sealing and are aided with " O " shape seal ring, and wherein " O " shape seal ring only is subjected to an amount of extruding and is not subjected to strong extruding, so sealing Q-percentile life is long.Also be added with seal ring in the valve body and in the foot pump.2 principles, simple in structure, easy for installation.The sealing of valve is different with traditional approach, the mode of its unlatching has then been abandoned chain in the mechanical parts or lever, bracing structure, adopted simple hydraulics, from the water source, draw working medium (need not to add in addition medium also not consumes energy) dexterously and can also compensate its loss automatically, make working medium become pressured fluid in the pump mode again, rely on incompressible characteristic of liquid to make to open the required merit of valve.This is the utility model biggest advantage.Reason is very complicated, conceive but extremely ingeniously, uses rare fault, and device is quite simple again simultaneously, and caused the convenience of installing therefrom: water-saving valve is partly identical with the installation of common valve.The installation of foot pump only needs to open a size, hole that the degree of depth is suitable with percussion drill on terrace to old transformation of facility, be fixed to bury get final product with cement, to newly constructed facility then when the construction while pre-buried.3 life-spans are long, and are easy to maintenance.From the theory structure of product, there is not flimsy link, hydraulic system has replaced chain or pull bar, and the possibility of damage reduces.The component part of entire product, the design of its shape, the selection of material all can guarantee long-term work, steps on not badly, plays not bad.The seal ring of rubber product diminishes, and it is changed also only needs to use conventional instrument.

The utility model health, convenient, reliable, water saving, moderate cost.The use of the utility model maximum is the sink of washing one's hands of public place.Because need not when using to turn valve and only need one to step on hand, the people is leaked from closing voluntarily not have, lift pin during soap in the using process and cut off the water supply, stepping on water again comes again, so the effect at saving water source is obvious.Statistics according to one's analysis, general water tap in use have 1/2nd to 1/3rd water to slattern approximately, so the water-saving rate of the foot-operated water-saving valve of this kind hydraulic type can reach more than 55%.And can think this moderate product price, can accept for the people.As economic benefit from long-term use, because the effect of its water saving can not be ignored, its long service life in addition again, consumes energy not, but so the foot-operated water-saving valve of this hydraulic type is recouped capital outlay in short-term after using, its advantage is conspicuous.
