Abstract

The utility model relates to a water tap, which is composed of a triple valve body, a valve core, a valve rod, a valve cover, a pull handle, and a sealing ring, wherein, a jagged annular slot is arranged on the outer side of the upper section of the valve cover; pointed teeth are arranged on shrapnels which are uniformly distributed on the base of the pull handle, and the pointed teeth are clamped in the jagged annular slot to form a water tap with gears. The utility model can be used for effectively controlling water output, and can be used for solving the problems of self locking and water stolen. Simultaneously, a cylindrical positioning wall of the outer layer of the valve core is changed into a positioning rib, the probability that the valve core is clamped by impurities in water to failure is lowered, and the service life of the water tap is extended. Because of the weight is lightened, the valve core can be floated up when water pressure is smaller, and the water tap can have larger water flow.

Description

A kind of water tap

The utility model relates to a kind of water tap.

The patent No. is that 94238535.7 water tap is made of three way valve, spool, valve rod, valve gap, carrying handle and seal ring.The spool outer wall area of this water tap is bigger, and between the valve pocket inwall easily by the impurity jam in the water, the spool activity is obstructed, influence the effect of closing of water tap, cause the waste of leaking.Owing to do not consider the abnormal phenomenon of tap water pressure, this kind water tap does not have self-locking device, opens and closes plug and is opened by the current shake sometimes, produces water clock.This water tap does not have gear, control water yield inconvenience.In addition, this water tap can't solve steathily water problems, just allows water droplet and water meter does not rotate.

The purpose of this utility model provides a kind of water tap that can self-locking.

Second purpose of the present utility model provide a kind of when hydraulic pressure is low the also floaty water tap of spool.

Another purpose of the present utility model provides a kind of water tap that gear is arranged.

The utility model also has a purpose to provide between a kind of spool outer wall and the valve pocket inwall to be not easy by the water tap of impurity jam.

Last purpose of the utility model provides a kind of water tap that can not steal water.

The purpose of this utility model can realize by following proposal: a kind of water tap, comprise three way valve, be placed in spool, valve rod, valve gap on the protruding seat of body cavity, draw and seal ring, the spool outer wall is equally distributed at least three positioning bars, because cylindrical shape location wall makes positioning bar into, outside area greatly reduces, and has greatly reduced by the possibility of impurity jam, simultaneously, because spool weight saving also can be floated than hour spool at hydraulic pressure, and bigger current can be arranged; Valve gap epimere outer wall is provided with jagged annular groove; Draw the pointed tooth on two shell fragments that are symmetrically distributed on the base is stuck in the annular groove.Because shell fragment is made of plastics, has elasticity, on carry or down by drawing handle, the shell fragment pointed tooth can slide between adjacent grooves, each bar groove just forms a gear, when particularly opening, the control water yield controls the little water yield just easily, and, because the effect of elastic force will be reached first grade at least, can not reach half grade, also just can not steal water; Simultaneously, because the effect of elastic force, this water tap can self-locking, can not held by the current shake.

The utility model is owing to be provided with annular groove and supporting with it shell fragment pointed tooth, and having played has gear, self-locking and prevent the effect of water steathily.Because cylindrical shape is located wall makes positioning bar into, greatly reduced spool by the possibility of jam, simultaneously,, bigger current can be arranged because spool weight saving also can be floated than hour spool at hydraulic pressure.

Accompanying drawing is the sectional drawing of water tap.

Wherein, the 1st, water nozzle; The 2nd, the water nozzle seal ring; The 3rd, filter net sheet; The 4th, valve body; The 5th, the protruding seat of valve body seal ring; The 6th, big valve core; The 7th, valve gap; The 8th, draw a base; The 9th, draw handle; The 10th, draw an inner cap; The 11st, shell fragment; The 12nd, transparent cover; The 13rd, valve rod; The 14th, spacing collar; The 15th, last protecting sheet; The 16th, valve stem packing ring; The 17th, following protecting sheet; The 18th, the small valve core seal ring; The 19th, small valve core; The 20th, valve seals; The 21st, the big valve core seal ring; The 22nd, retainer ring.

Describe in detail below in conjunction with accompanying drawing:

A kind of water tap, three way valve 4 spins with valve gap 7, accompanies valve seals 20 between the two; Be nested with seal ring 5 on the protruding seat of the inner chamber of valve body 4, spool 6 is pressed on the seal ring 5; Spool 6 skins are interval at least three positioning bars uniformly, and the upper end of spool 6 internal layer core bodys is nested with big valve core seal ring 21; Seal ring 21 is compressed by the lower end of valve rod 13, and it is solid to add thermosol after the upper end of valve rod 13 is passed down protecting sheet 17, valve stem packing ring 16, goes up protecting sheet 15, valve gap 7 tops and drawn an inner cap 10; Valve gap 7 epimere outer walls are provided with the flexuose annular groove; Draw 9 enclosing cover with draw a base 8 to spin, draw an inner cap 10 to be enclosed within on the base 8, draw the pointed tooth on two shell fragments 11 of symmetrical distribution on the base 8 is stuck in the annular groove of valve gap outer wall.

In order to improve the unlatching effect, small valve core 19 can be set between big valve core and valve rod, the hypocone of small valve core 19 is pressed on the big valve core seal ring 21, is nested with small valve core seal ring 18 on the small valve core 19 internal layer core bodys, and small valve core seal ring 18 is compressed by the valve rod lower end.

Claims
