Background technique
Existing a kind of foot-operated pipeline valve, its working principle be, valve is when closing, and pressured spring is pressed in the top with spool, and the entity Cylinder of spool partly blocks cold and hot two water inlets, and valve is " pass " state; During water, spool overcomes spring thrust by pull bar and pulls down, and makes under shell portion displacement two water intakes of spool, thereby makes the valve open water flowing, is " opening " state.When as installed was used, the pulling of pull bar realized by pedal.There is following problem in this valve: 1 sealing is main to realize by the spool cylndrical surface very easily wearing and tearing in this cylndrical surface, in case the stuck akinesia of the too small then spool in gap promptly is a problem in the excesssive gap sealing.Inconvenience is installed by 2 mechanisms.Foot-operated part is made up of metal construction, and structure is scattered, and member is coarse, and trouble is installed, and the length of pull bar and the angle of wood clapper are also difficult to be adjusted.3 inconvenient maintenance, some cold and hot mixing foot valve also exists scurries water problems.In addition, also have 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; And this device wants electricity consumption, increased trouble and the power consumption installed.Electricity mixes with water simultaneously; Increased the possibility of fault.
Summary of the invention
The utility model is to overcome the shortcoming that above-mentioned prior art exists, and provides the cold and hot mixing of a kind of improved energy-saving hydraulic formula to ride water-saving valve, and is particularly suitable to the hot and cold water shower.
Hydraulic type is ridden showering, include the pump housing 1 and valve body 21, it is characterized in that, valve body 21 inner chambers have cold water valve core 19 and hot water spool 24 respectively, spool 19,24 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; Each spool middle part has a circle groove, forms 27, two cavitys 27 of two cavitys that do not communicate with valve interior wall and is communicated with two spools water outlet 25 separately respectively; Two center spools respectively have pod apertures 22; Two pod apertures one ends are communicated with the connecting tube 9 of the pump housing 1, and the other end is communicated with two water intakes of valve body respectively; 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; Valve body 21 has water intake and mixed water outlet, water intake and mixed water outlet communication with cavity; The water outlet 25 of cold water valve core 19 and hot water spool 24 is communicated with mixed water outlet 26.
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.
The other end of pump core 4 is fixed with bowl ring 10.
The intake-outlet 23 of the pump housing is communicated with connecting tube 9.
Working principle of the present utility model is that (pressure is greater than 0.1kg/cm with hot and cold water source respectively when hot and cold water intake
2) when connecting, two spools are pressed to the top by stage clip, the conical surface seal ring on it and the conical surface driving fit of valve body form two place's reliable sealings, stop hot and cold current from mixing the water outlet discharge and making valve be " pass " state simultaneously.The pod apertures of hot water or cold water's spool central authorities upper end is by an one-way valve of being made up of inner spool, and its permission water upwards flows through and can not reverse flow.The water that flows to the top flows in the foot pump by connecting tube in valve body, till being full of.Foot pump is when installing first, and the water that attracts from twin-core water-saving valve body can not flow foot pump, and available pulling taken out 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 pump cover, just the water that the pump core is extruded is compressed into the twin-core water-saving valve by connecting tube.Because the effect of one-way valve, water can not flow through pod apertures, can only make two spools overcome stage clip pressure and push it against the below and open valve separately, makes bivalve all be " opening " state.Converge behind the sealing surface of hot water or cold water by valve, flow out from the mixing water drain opening.If unclamp the pump core, then two stage clips are pressed to two spools the top again, and the pump core lifts again, and hot and cold two valves are " 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 " 0 " shape seal ring, and wherein round section joint ring only is subjected to an amount of extruding and is not subjected to strong extruding, and the life-span is long so sealing is reliable.To in the valve body and the sealing in the foot pump all be added with seal ring, so sealing is absolute reliable.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, pull bar, and adopted simple hydraulics, from the water source, drawn 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 a great advantage of the present utility model.Reason is very complicated, conceive but extremely ingeniously, uses rare fault, installs quite simple again simultaneously.Caused the convenience of installing therefrom: the water-saving valve part is identical with the installation of common tee union.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.In addition,, do not make water shutoff switch, so its life-span also greatly prolongs because modulating valve is only made Flow-rate adjustment.4 do not scurry water problems.Under the situation about connecting simultaneously at hot and cold water source, no matter the utility model is " pass " state or " opens that " state is all exhausted not to be had and scurry water problems.
The utility model is reliable, and is convenient, health, and water saving, moderate cost mainly is applicable to shower room, also can be used for the hot and cold water washbasin.Owing to need not when using to turn the valve open tap and only need one to step on, must close voluntarily when the people leaves not have and leak with hand.Lifting pin during soap in the using process and cut off the water supply, step on water again and come again, is obvious so save the effect at water source, and water-saving rate can reach more than 40%; And this moderate product price, can accept for the people.During use, each water-saving valve of valve only is responsible for Push And Release, can not make the water yield and regulate.Therefore hot and cold water source with should install a flow control valve separately additional before water-saving valve is connected, adopt common water valve also can.
