The utility model causes the three-joint valve core to be changed into the two-joint valve core, and therefore, the structure is simple. The switching mode of the lifting and pressing upward and downward is changed into the switching mode of the rotation leftward and rightward, which is consistent with the usually switching habit, and the water quantity is convenient to control. The water is sealed by water pressure, and sealing elements are not easy to wear. The utility model is made of engineering plastics, and has the advantages of no rust, toughness, and high durability.

Description

Durable water tap

The utility model relates to the durable water tap on the water supply pipe in a kind of daily life.

In the prior art, most of water taps adopt metallic material to make, its seal water structure mostly is rotary spool and compresses rubber ring and come water shutoff, the long-time use can produce corrosion phenomena, rubber ring makes that it occurs dripping, water leakage phenomenon because rotation friction damages easily, and keying speed is slow, also make the hydraulic pressure instability of water pipe, produce vibration and make a noise.No. 942385357, Chinese patent application disclosed " a kind of water tap ", it be on the inner chamber valve seat of three way valve, be mounted with moving up and down, the center offers the big up and small down spool of through hole, also have shape similar on the spool, the center also has the middle spool of through hole, and the keying plug that is connected with valve rod is arranged above the spool of center, the upper end portion of valve rod is fixed with and is nested with on the base of valve gap top and carrying handle moving up and down, carrying handle spins with base mutually by the Adjusting ring on it, offers a word or cross degree of tightness groove from an end face axial on the connection inner ring wall of Adjusting ring.Though it adopts hydraulic pressure to carry out water shutoff, spool is three joints, and its structure is complicated, and adopts pressure-raising mode switch water tap up and down, and is different with common rotary switch mode, if this switch of careless rotation is easy to cause switch to damage.

The purpose of this utility model aims to provide a kind of hydraulic pressure water shutoff, durable water tap simple in structure, consistent with common rotary switch mode of utilizing, to overcome the deficiencies in the prior art part.

A kind of durable water tap by this purpose design, comprise the valve body that is provided with entery and delivery port, the valve body upper end is connected with hollow valve seat, be provided with taper valve core in the valve seat, the upper end of valve seat is connected with switching knob, its structure characteristic is that described taper valve core comprises small valve core and the big valve core of being with valve rod, the setting of connecting up and down of little, big valve core, and the valve stem tip of small valve core is connected with the inner cap of switching knob; The outer surface of described hollow valve seat is provided with the guiding arc groove; Described switching knob endoporus is provided with small boss, and small boss inserts in the guiding arc groove, and can rotatablely move up and down along the guiding arc groove, drives small valve core simultaneously and moves up and down, to realize the switch water tap.

Described guiding arc groove is generally the twin-feed spiral groove.The small boss of described switching knob is generally and is symmetrical arranged, and is 2.

The utility model changes original three joint spools into two joint spools, and is simple in structure; The pressure-raising on-off mode is the left rotation and right rotation on-off mode about changing, and meets common switch custom, and water yield control is convenient; Utilize the hydraulic pressure water shutoff, Sealing is not easy to wear; This water tap adopts engineering plastics to make, and can not get rusty, and is tough and tensile durable.

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

Fig. 1 is an example structure schematic representation;

Fig. 2 is the structural representation of valve seat among Fig. 1;

Fig. 3 is the left view of Fig. 2.

Referring to accompanying drawing, valve body 14 is horizontal T shape, and the upper end screw thread is connected with hollow valve seat 17, constitutes the water shutoff cavity with valve body.The upper end of valve seat 17 is connected with switching knob 18.Valve body 14 lower end screw threads are connected with water outlet 12.Valve body 14 inner chamber water outlet places are provided with a boss, and the big rubber ring 9 of bowl-type is set on the boss, and taper big valve core 13 is arranged on the big rubber ring 9.The taper small valve core 3 of band valve rod is arranged on the bowl-shape rubber ring 8 of big valve core 13, and the valve stem tip of small valve core 3 is connected movingly with the inner cap 1 of switching knob 18.The outer surface of hollow valve seat 17 is provided with two guiding arc grooves 20, and switching knob 18 endoporus are symmetrical arranged two small boss 4, and small boss inserts in the guiding arc groove 20, and the endoporus of switching knob 18 is inserted on the top of hollow valve seat 17, and fixing by positioning ring 2.Switching knob 18 can rotatablely move up and down along the guiding arc groove, drives small valve core 3 simultaneously and moves up and down, to realize the switch water tap.

The water inlet of this water tap is provided with filter screen 15, to filter entry, reduces odds and ends and flows into, and prolongs the life-span of inner rubber seal ring.The water outlet place is provided with filter screen 10 and steel wire 11, carries out double filtration.Water outlet 12 internal diameters are cylindric, so that insert with the isometrical tube of glue of its internal diameter, press water outlet 12 inwalls because the effect of hydraulic pressure can make sebific duct expand after the water flowing, and can not come off.5,6 is seal ring among the figure, and 7 is the O RunddichtringO; 16 is ring, to hide the pipe thread that exposes; 19 is the switching knob top cover.

During boiling water, switching knob 18 drives small valve cores 3 and moves upward, and the water between big valve core 13 and the small valve core 3 flows out valve body 14, thereby the generation differential water pressures rushes at the top of valve seat 17 fast to big valve core 13, realizes quick boiling water.When closing water, switching knob 18 moves downward, and top cover 19 forces valve rod and small valve core 3 to move downward, at this moment, valve body 14 has been full of water with the cavity that valve seat 17 is formed, because the effect of hydraulic pressure compresses big valve core 13 to small valve core 3, big valve core compresses the big rubber ring 9 of bowl-type again, thereby realizes the hydraulic pressure water shutoff.

This water tap appearance is airflow design, and except that seal ring, all part is made by engineering plastics.
