Abstract

The utility model discloses a durable water saving tap, which comprises a valve body, a valve core arranged on the valve body, a pressing screw and an adjusting cap arranged on the valve core. The utility model is characterized in that the valve core is arranged on the left part of the adjusting cap and the left end of the valve core is in a conical shape. The minimum diameter of the part of the valve core matched with a water inlet and a water outlet is not smaller than hole diameters of the water inlet and the water outlet. The big end of the conical part of the valve core is in a table shape and the residual part of the small end of the conical part is in a more-half ring shape. The valve core is combined with the adjusting cap through a square convex table and connecting screws. The pressing screw always enables the valve core and the valve body to be tightly matched by a spring. The purpose that the rightward direction along the axial direction of the valve core does not have stroke is guaranteed. The utility model adopts the structure to automatically compensate abrasion. The utility model effectively avoids dripping phenomenon and can prolong the service life. The utility model also has the characteristics of simple structure and convenient processing and use.

Description

Durable water-saving tap

The utility model relates to a kind of durable water-saving tap.

Water tap at present both at home and abroad commonly used is a kind of to be to rely on adjusting screw rod control spool to move up and down the open and close valve, makes current unimpeded or close.Sealing between spool and the valve body relies on rubber sheet gasket, and under the long-term big pressure effect of adjusting screw rod, Sealing is fragile, produces weeping, causes the waste of economy and natural resources, has also influenced the working life of water tap.Also having a kind of is to rely on spool rotary alignment osculum to realize opening and closing, and the matching gap of its sealing main dependence spool and valve body can occur wearing and tearing to compensate automatically weeping occurring in long-term the use because of spool.

The purpose of this utility model just is to provide a kind of simple in structure, long service life, can effectively prevents the water tap of water clock.

The purpose of this utility model can realize by following measure:

The utility model comprises valve body, be placed in spool and the housing screw on the valve body and be placed in adjusting cap on the spool, it is characterized in that: be mounted with spool at adjusting cap left, the spool left end is tapered, spool taper position and the minimum diameter at water inlet and the osculum place of matching are equal to or greater than the aperture of water inlet and osculum, the big end at spool taper position is arranged to the platform shape, the small end remainder at taper position is arranged to most ring-types, is positioned at the right-hand spring and the housing screw of being mounted with successively of the big end of cone on spool.

Right-hand end at spool in the utility model is provided with square boss, and the right-hand member of spool combines by this square boss and joint bolt and adjusting cap.

In adjusting cap inboard one projection is set in the utility model, on valve body, a projection also is set with the corresponding position of adjusting cap.

Adjusting cap in the utility model is positioned at the dead ahead of blasthole, and osculum is positioned at the top of regulating cap.

Because adopting, the utility model regulating cap left arrangement spool, the spool left end is arranged to taper, taper position and the minimum diameter at water inlet and the osculum place of matching are equal to or greater than the aperture of water inlet and osculum, the big end at spool taper position is arranged to the platform shape, the small end remainder is arranged to most ring-types, on taper valve core, be positioned at the right-hand spring and the housing screw of being mounted with successively of the big end of cone, the pressure of spring closely cooperates spool and water inlet osculum all the time, and guaranteeing does not have stroke along poppet shaft to the right direction.In view of the above, the utility model can make spool taper position and water inlet and osculum closely cooperate, make the taper position simultaneously under the pressing force of the spring effect, automatically compensate for wear, can effectively avoid weeping, and can increase the service life, also have simple in structure, processing and characteristics easy to use simultaneously.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1 is the sectional view of the utility model when the spool closed condition.

Fig. 2 is the sectional view of the utility model when the spool opening state.

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

As shown in the figure: the utility model comprises valve body 1, be placed in spool 5 and housing screw 4 on the valve body, spool 5 left ends are tapered, spool 5 taper positions and the minimum diameter at valve body 1 water inlet and the osculum place of matching are equal to or greater than the aperture of water inlet and osculum, the big end in spool 5 taper positions is arranged to the platform shape, taper position small end remainder is arranged to most ring-types, housing screw 4 closely cooperates spool 5 taper positions and water inlet and osculum by spring 6, the right-hand end of spool 5 is provided with a square boss, spool 5 matches with transmitting torque with regulating cap 2 by this boss, and spool 5 and adjusting cap 2 combine by joint bolt 3.

The utility model working principle is as follows: spool 5 remains at the effect inferior pyramidal position of spring 6 impacting forces and valve body 1 water inlet and osculum and closely cooperates, assurance does not axially have stroke to right along spool 5, to regulate the rotation of cap 2 up times during unlatching, make the annular position in spool 5 taperings detach the water hole, current are promptly unimpeded; When closing, will regulate the rotation of 2 inverse time of cap, the projection (a) of regulating cap 2 inboards contacts with the projection (b) of valve body 1, regulates cap 2 and stops rotation, and osculum is sealed at the annular position in spool 5 taperings simultaneously, and current are promptly closed.Cooperate by the conical surface between spool 5 and the valve body 1, under the impacting force effect of spring 6, compensate for wear automatically, thus guaranteed tightness closed between spool 5 and water inlet and the osculum, effectively avoided water clock.
