Abstract

Disclosed is a tap water pressure-limiting water-saving valve, which mainly comprises a tee pipe, a valve core, a valve, a restoring spring, a driving bar, a crown bar and a valve diaphragm. The utility model is characterized in that the valve core is sleeved on the water inlet of the tee pipe, one end of the valve core is provided with a valve core pin, the valve bar which is connected with the valve in the valve core is in a polygon shape and the end of the valve bar is provided with a bayonet, the opening on the top end of the tee pipe is provided with a pressure regulating cap, a top cap, a restoring spring, a valve diaphragm and a top bar in turn, wherein the pressure regulating cap can be screwed or opened on the top cap along the vertical direction, the restoring spring is arranged in the pressure regulating cap and is connected with the upper end of the top bar, the lower end of the top bar is provided with the top bar pin, the valve diaphragm is fixed under the top cap and is connected with the middle segment of the top bar in a sealing way, and can do elastic movement from the top to the bottom as the top bar, the driving bar is a curved lever, which utilizes a connecting valve core pin to be a rotation shaft point, and both ends are respectively connected with the bayonet and the top bar pin. The utility model has the advantages of simple structure, low cost and good pressure-limit water-saving effect of the high-pressure tap water.

Description

A kind of tap water pressure limiting water-saving valve

Technical field

The utility model relates to a kind of tap water pressure limiting water saving fixtures, a kind of specifically pressure limiting water-saving valve.

Background technique:

The building in city is more and more higher at present, in order to supply water for high-rise user, water supply department adopts engine driven supercharging, methods such as classification lifting are sent water, when tap water arrives each user, hydraulic pressure is all big especially, but in real life, except special industries such as fire-fighting need with the high pressure water, most users, resident's domestic water does not need high pressure water, and high pressure water enters family, not only causes the trouble that The water splash in all directions turning on the tap, and cause current fast greatly because of water pressure, many water also just do not make full use of and pour off, and cause the water tap water clock easily simultaneously yet, greatly waste limited water resource.

Summary of the invention

The purpose of this utility model is to provide a kind of simple in structure, cheap pressure limiting water-saving valve.

The purpose of this utility model is achieved by the following technical solution: a kind of tap water pressure limiting water-saving valve, mainly comprise three-way pipe, spool, valve, Returnning spring, drive link, push rod, valve film, it is characterized in that: be with a spool at the water inlet place of three-way pipe, spool one end is provided with the spool latch, and the end that the interior valve rod that connects valve of spool is many ribs shape and valve rod is provided with bayonet socket; The open-topped place of three-way pipe is provided with pressure regulating cover, top cover, Returnning spring, valve film, push rod successively, pressure regulating cover can vertically be tightened on top cover or open, be provided with Returnning spring in the pressure regulating cover, Returnning spring is connected with the push rod upper end, the lower end of push rod is provided with the push rod latch, the intermediate section that the valve film is fixed under the top cover with push rod is tightly connected, and can do elastic movement with moving up and down of push rod; Drive link is a curved bar, and drive link is to connect spool latch place as pivot point, and two connects bayonet socket and push rod latch respectively.

The utility model beneficial effect is: valve body structure is simple, cost is low, and pressure limiting is effective, can effectively control the waste of water resources.

Description of drawings:

Fig. 1 is the utility model embodiment's a generalized section;

Fig. 2 is the utility model embodiment's a valve core structure schematic representation;

Fig. 3 is the utility model embodiment's valve, a stem structure schematic representation;

Fig. 4 is the utility model embodiment's a push rod structure schematic representation.

Among the figure, 1, three-way pipe; 2, spool; 3, valve; 4, Returnning spring; 5, drive link; 6, push rod; 7, valve film; 8, spool latch; 9, valve rod; 10, bayonet socket; 11, pressure regulating cover; 12, top cover; 13, push rod latch.

Embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples.

Shown in Fig. 1,2,3,4, on prefabricated spool 2, put valve 3, valve rod 9, the spool latch 8 on spool 2 tops connects the pivot point of curved drive link 5, one of drive link 5 is stuck on the bayonet socket 10 of valve rod 9, the other end is connected on the push rod latch 13, the above-mentioned parts that connect are packed into from the water inlet of three-way pipe 1, stretch out from the top of three-way pipe 1 push rod 6 upper ends, on push rod 6, load onto valve film 7, Returnning spring 4, then top cover 12 is covered that to tighten a valve film 7 fixing, pressure regulating cover 11 on Returnning spring 4 loam cakes is suitably tightened.After the utility model inserted running water pipe, during use, when water tap is closed,, drive on the push rod and move valve closing because the pressure of tap water makes valve film jack-up greater than the elastic force of Returnning spring; When water tap is opened, threeway tube chamber internal water pressure reduces, under the elastic force effect of Returnning spring, make push rod move down valve opening, water enters the back because pressure increases, and makes the size of valve opening by the elastic force decision of Returnning spring, the therefore tightness of adjusting by pressure regulating cover, the urgency that is the can regulate current is slow, and effectively controls hydraulic pressure.
