Abstract

The utility model discloses a water-saving valve which can be adjusted automatically, comprising a valve body, the external contour of the valve body presents a ladder shape. The top of the small endof the valve body is sealed, a water inlet channel which is used to conduct a water inlet and a water outlet is opened on the valve body vertically. Wherein the water outlet is opened at the peripheryof the side face of the small end of the valve body and is distributed presenting odd number in equal interval, an elastic baffle which at lease covers the water inlet partly is arranged at the spacing of the lower side of the water inlet, the gap between the elastic baffle and the water inlet presents the ladder shape. The water inlet is the small end, a limit slot which is matched with the elastic baffle is opened at the upper side of the elastic baffle, the middle of the valve body is formed and bulged outwards with a clamping regular truncated cone or a multi-surface regular prismoid which has a narrow upper part and a wide lower part. In the utility model, the water flow is decreased through the mode that the elastic baffle is deformed under the water pressure which is beyond the setvalue to compress the underwater area of the water inlet, thereby the aim of saving water is realized. The water outlet is opened at the periphery of the side face of the valve body, the water potential also can be activated, the water pressure of effluent water is decreased. In addition, the valve body of the utility model uses the mode of being cast in one body, so that the structure is simple,the using is convenient, and the cost is low.

Automatically regulate water-saving valve and comprise the inner valve body of longitudinally opening intake tunnel, open the water outlet that communicates with intake tunnel on this valve body, the water intake that it is characterized in that described intake tunnel longitudinally spacing is provided with one and covers the elastic baffle of this water intake to small part, forms the lateral intake gap between described elastic baffle and the water intake.

Described intake tunnel is stepped, its big end outwardly, its small end outer end is described water intake, spacing setting and cover the small end outer end of this intake tunnel to small part between described elasticity plate washer and the intake tunnel small end outer end forms described lateral intake gap between described elasticity plate washer and the small end outer end.

Described valve body external frame is longitudinally stepped, the big end of described valve body is the blocking section, described small end and blocking section are integrally formed, the small end of valve body is established several described water outlets that communicate with intake tunnel, the cross-section area of water outlet is less than the cross-section area of intake tunnel, the vertical waterexit end sealing of described intake tunnel, described several water outlets are provided with along valve body small end perisporium equi-spaced apart.

Be formed with the banded arc restraining groove that matches with the elasticity plate washer between described elastic baffle and the water intake, this restraining groove communicates with the big end of water intake and intake tunnel, and vertical degree of depth of the big end of described intake tunnel is greater than vertical degree of depth of arc restraining groove.

The number of described water outlet is an odd number.

The small end of described intake tunnel is a cylindrical body, the big end of described intake tunnel is the groove that is arranged on intake tunnel small end both sides, described groove internal surface is the part of spheroid, the length direction of described arc restraining groove, elasticity plate washer and the length direction of the big end of intake tunnel are and intersect setting looking up direction, and the width of elasticity plate washer is less than the length between two grooves.

Be that described elastic baffle covers described water intake in vertical direction fully.

The big end of described valve body is the blocking section, and described small end is the water exit end integrally formed with the blocking section, and described blocking section is that the longitudinal cross-section is trapezoidal cone or multiaspect cone.

The beneficial effects of the utility model: the utility model is by being provided with an elastic baffle in water intake bottom spacing, the gap of elastic baffle and water intake exceeds into water actinal surface, elastic baffle is out of shape under the driving of hydraulic pressure like this, reduce water intake the entry area, thereby advance few water flow, water outlet of the present utility model is in addition opened on side of valve body, also can play the activation flow of water, reduce the effect of hydraulic pressure, thereby realize the purpose of water saving.Also have the utility model valve body to adopt integrally casting, simple in structure, easy to use, cost is low.

Description of drawings

The X-axis generalized section that Fig. 1 regulates water-saving valve automatically for the utility model;

Fig. 2 regulates the worm's eye view of water-saving valve automatically for the utility model;

The Y-axis generalized section that Fig. 3 regulates water-saving valve automatically for the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is further set forth.

Shown in Fig. 1,2 and 3, the utility model is regulated water-saving valve automatically and is comprised valve body 2 and elastic baffle 6:

Valve body 2 adopts integrally casting, valve body 2 exterior contours are stepped, valve body 2 central longitudinal are to having cylindrical body intake tunnel 5, valve body 2 comprises that (the valve body small end is a water exit end for Rotary-table blocking section 22 and cylindrical body water exit end 23, the big end of valve body is the blocking section), opened cylindrical body water outlet 4 on the side perimeters of water exit end 23, water outlet 4 equidistantly is distributed on the same horizontal plane of side of water exit end 23, and the number of water outlet 4 is an odd number.The shape of blocking section 22 is up-narrow and down-wide, intake tunnel 5 vertically extends to valve body 2 bottoms always, blocking section 22 bottom surfaces form a circle, the circle that forms with blocking section 22 bottom surfaces is the center of circle then, dig out several 1/4th spheroids respectively (during in blocking section 22 when the thickness low LCL of blocking section 22, spheroid may exceed water exit end), so just formed water inlet gap 3, certainly the shape here is not limited to 1/4th spheroids, can be the shape of satisfying the demand arbitrarily, be stepped as long as satisfy water inlet gap 3, and wherein water intake 4 is that small end is just passable, the utility model is an example with 2 1/4th spheroids only, but not only is confined to this.Inner chamber still forms the circle of a horizontal plane near the extreme higher position part of spheroid, this circle is water intake 1, upwards hollow out a circular arc restraining groove 7 from valve body 2 bottoms again, restraining groove 7 be positioned at water intake 1 under, width is the diameter of water intake 1, and perpendicular to the circle center line connecting of 2 1/4th spheroids, still can proper functioning when the limit position in order to guarantee this water-saving valve, water inlet space 3 vertical degree of depth are greater than restraining groove 7 vertical degree of depth.
