Abstract

The utility model discloses a self-closing water-saving valve, and the water inlet and the water outlet of the utility model form a vertical state. The inside of the self-closing water-saving valve is vertically provided with a valve core which can move in the vertical direction in a spacing way, and the front side thereof is provided with a supporting structure which is matched with the inner movable members of two movable members in the water inlet; the back side is provided with a convex structure which is matched with a poking structure end inside the self-closing water-saving valve of a level type handle. The outer end of the outer movable member of each movable member is provided with a closed structure which can be matched with the end part of the water inlet, and the movable members are matched with each other in a contact way by the end parts of the two movable members.

Description

Self-closing water-saving valve

The utility model relates to a kind of water valve, have the water-stopping self-closing function and reach the purpose of water saving.

The products such as water tap, water valve that have the water-stopping self-closing function at present more report, owing to can prevent to cause the effect that the continuous phenomenon of current when coming water again has water saving because of forgetting to close tap or valve, comes into one's own.But how comparatively complicated the structure of these valves is at present, and manufacturing is difficult for, and cost is also higher, also is not easy to maintenance.

The purpose of this utility model is for this reason and provides a kind of simple in structure and the water-saving valve that has the water-stopping self-closing function equally is desirable and reliable through test effect.

Water-saving valve of the present utility model is the form that water intake and water outlet are vertical state.In valve, be provided with one and can make the spacing spool that moves up and down with vertical position, it is met and is provided with a holder to the suitable position place, middle part of water inlet oral-lateral and lifts structure, the tight contact matching of inwall of its intake dorsad oral-lateral and valve casing, and its suitable position place, middle part is provided with protruding structure and is arranged on the valve casing between corresponding limiting area, it also matches with the structure of stirring of valve the inner of the level type handle that has rotating support point simultaneously, and the other end of level type handle is positioned at valve and is the manually-operable end outward.But be provided with the shaft-like movable part of inside and outside two independence and freedom activities in the valve of water intake one side, the outer end of its China and foreign countries' movable part has the enclosed construction that can cooperate with the water intake end; Respective outer side edges is lifted in the inner of interior movable part and the holder on the spool; Make contact matching with its end separately between inside and outside two movable parts.

In above-mentioned structure, protruding structure on the said spool and handle valve the inner stir respective outer side edges the time, can take single convex parts and Y type shift fork type to stir the mode of respective outer side edges, or play the mode that structure and driving lever type are stirred respective outer side edges with biconvex, maybe can take to have other suitable mode of similar toggle action.

Being positioned at enclosed construction that the outer movable part of valve water inlet oral-lateral cooperates with the water intake end except that being positioned at port, is to be positioned at outside the port more easily.Contact matching position between inner and outer movable spare, for increasing the contact position, have an end structure that can have expansion in the termination of both sides at least, for example can be the integrated structure of forms such as gradually big taper, spindle, or add expand the type structure.

Below further specifying structure of the present utility model and working principle with example shown in the drawings, is the qualification that the utility model scope is made but should not be construed as this.

Structure during Fig. 1 the utility model water-saving valve closed condition

State during Fig. 2 Fig. 1 opening of valves

As shown in the figure, the water intake 6 and the water outlet of this water-saving valve are vertical state, identical with water outlet vertical position is provided with one and is subjected to valve casing 3 restrictions can only make the moving spool 4 of upper and lower displacement in valve, it is met to the middle part of water inlet oral-lateral has an awl nest shape holder to lift structure 10, and it has a protruding structure 11 to be arranged between valve casing 3 corresponding limiting areas 13 in middle part of water intake one side dorsad.What cooperate with this protruding structure 11 is that the Y type shift fork type that the level type handle 1 that has a rotary supporting shaft 2 is positioned at valve the inner is stirred structure 12, and the valve outer end of handle 1 is the manually-operable end.But in the valve of water intake 6 one sides, be provided with the thick stick shape movable part of inside and outside two independence and freedom activities.The outer end of its China and foreign countries' movable part 14 is positioned at outside water intake 6 ports, and has the door shape enclosed construction 7 and the inclined-plane that resets accordingly that can cooperate with the sealing of inlet end do; The inner of interior movable part 9 is lifted structure 10 with the awl nest shape holder on the spool and is done to hold in the palm to lift to cooperate; Contact matching is made in end between this two movable part, and therebetween separately the end all have one and can increase the end structure 5,8 of the expansion of contact position.

When valve is in closed condition as shown in Figure 1, spool 4 falls to being in minimum spacing position by self gravitation, interior movable part 9 is lifted structure 10 with the holder on the spool and is also fallen naturally, be in skewed position, two movable parts 14 and 9 crow flight distances that constitute are for the shortest, under the water pressure pushing outside water intake, the enclosed construction 7 of outer movable part 14 outer ends closes water intake 6, the anhydrous outflow of the water outlet of valve.

When the operating end that presses down handle 1, level type handle 1 is stirred structure 12 by the inner and will be lifted on the spool 4, holder on the spool is lifted structure 10 and is moved on the movable part 9 in also driving simultaneously and become the level position, the crow flight distance that inner and outer movable spare constitutes increases, with outer movable part 14 extrapolations, make enclosed construction 7 leave inlet end, water promptly enters in the valve and is flowed out by water outlet, is opening state shown in Figure 2 this moment.And the pressure of water can directly affact on the spool by two movable parts of linear state, makes it can keep being equilibrated at this opening state position.After water supply was cut off the water, water intake did not have outward that hydraulic pressure exists or hydraulic pressure is very low, did not have pressure or underpressure so that spool when remaining in the state of equilibrium of unlatching, and himself action of gravity is fallen it naturally.Movable part also is in the position thereupon in causing.In case resume water supply, the pressure of water will promote outer movable part water intake will be closed, and close valve automatically.Test result to this valve shows its working procedure and satisfactory for result and reliable.

On the said structure basis, suitable block card structure can also be set in water intake, store coming off in the process to prevent two movable parts in non-use.
