Description

Water tap with diaphragm

The utility model relates to that a kind of in the plumbing supplies water and the water nozzle of Guan Shuiyong.

At present, traditional water nozzle is made up of valve body, valve gap, follower, flap valve seal ring, screw thread valve rod substantially.This water nozzle volume is bigger, the structure more complicated, and after use a period of time, the filler of this water nozzle can be worn, and occurs metalling run out and preventing water phenomenon.Simultaneously, the valve rod of this water nozzle is to be immersed in the water all the time, and the time one is grown easy corrosion, influence the using effect of this water nozzle.And have only a port hole in the valve body of this water nozzle, so it has only a pass to remain silent.Seal ring can only be blocked osculum when closing, and can not close the water inlet, and this water nozzle was in closed condition when night, hydraulic pressure was higher, often high hydraulic pressure can penetrate from the slit between seal ring and valve body, and flow out from water outlet, produce water clock, cause waste. unblockedly

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provides a kind of volume little, and is simple in structure, valve rod can be by corrosion, and good sealing effect is not metalled run out simultaneously, do not emit water, water clock not, and can also have the diplopore barrier film water nozzle of key handle.

The purpose of this utility model is to reach by following measure: the basic model of this water nozzle is to be made of valve body, valve gap, protective cap, rivet, handgrip, valve rod, stuffing box gland.Wherein on the blind hole bottom of valve body upper end, two through holes are arranged, water inlet with the valve body left end communicates, and another communicates with the osculum of valve body lower end, the shape of valve rod is middle one section and is threaded, the lower end has the integrated step shape cylindrical body of disk, also can be threaded for one section by the centre, step-like cylindrical body and a discoid valve that the lower end has little round platform are formed by connecting.Be inserted in undulatory stuffing box gland and the undulatory stuffing box gland below of valve rod, and stuffing box gland is the blind hole that is positioned at the valve body upper end.The screw in the middle of the valve gap is passed in the top of valve rod, and makes screw thread and the middle screw interlock mutually of valve gap on the valve rod, simultaneously protective cap is set on the top of valve rod, with rivet handgrip is riveted on the upper end of valve rod again.After then valve gap being pushed down stuffing box gland, be fixed on again on the upper-end surface of valve body.

The utility model can also stamp out a square blind hole on the upper-end surface of valve rod, and mix a lower end be square the head the key handgrip.Protective cap is fastened on the key bar of key handgrip simultaneously.

Its upper end of protective cap of the present utility model can be the top cover of enclosed shape, and it is the upper end that directly is placed in valve gap.

The utility model can also be installed one at the water outlet place of valve body again and take over head.

The utility model is described in further detail below in conjunction with embodiment: the outward appearance of valve body (1) is cast as substantially

Shape, on the blind hole bottom of valve body (1) upper end two through holes are arranged, one of them communicates with the osculum of valve body (1) lower end, and another osculum with valve body (1) lower end communicates, one section was threaded in the middle of valve rod (6) can be made, and the lower end has the integrated step shape cylindrical body of disk; Also can be threaded for one section by the centre, a step-like cylindrical body and a discoid valve (8) that the lower end has little round platform are formed by connecting.Be inserted in the undulatory stuffing box gland (7) below of valve rod (6).Stuffing box gland (7) is the blind hole that is positioned at valve body (1) upper end.The screw in the middle of the valve gap (2) is then passed in the top of valve rod (6), and makes screw thread and the middle screw interlock mutually of valve gap (2) on the valve rod (6).Simultaneously protective cap (3) is set on the top of valve rod (6), uses rivet (4) that handgrip (5) is riveted on the upper end of valve rod (6) again, then valve gap (2) is pushed down stuffing box gland (7) after, be fixed on again on the upper-end surface of valve body (1).Basic structure form of the present utility model that Here it is.Second kind of structural type is on the basis of preceding a kind of structural type; just the handgrip (5) with valve rod (6) upper end removes; and valve rod (6) upper part shortened; stamp out a square blind hole simultaneously in its upper-end surface; but also mix a lower end be square the head key handgrip (9), simultaneously protective cap (3) is fastened on the key bar of key handgrip (9).This just constitutes a kind of Tap with key, and it could open water nozzle after having only owner to take key handgrip (9), and the stranger can't open this water nozzle.More than this Tap with key be mounted in indoor.If on the basis of second kind of structural type, the top cover of enclosed shape is made in the upper end of protective cap (3), and it directly is placed in the upper end of valve gap (2), and it is not fastened on key handgrip (9).This just constitutes the third structural type of the present utility model---outdoor version Tap with key.Because it is outdoor that this water nozzle is installed in, the protective cap (3) of this top cover sealing can make the square blind hole of valve rod (2) upper end can not lived by more airborne fouls and foreign material filling, guarantees that it is easy to use.In addition, more than the water nozzle of three kinds of structural types, can install one at the water outlet place of their valve bodies (1) separately again and take over head (10), constitute the diplopore barrier film respectively and take over water nozzle, diplopore barrier film key indoor type adapter water nozzle and diplopore barrier film key outdoor version adapter water nozzle.

Use this class water nozzle, the only with hand counterclockwise direction is rotated handgrip (perhaps key handgrip), then valve rod just the internal thread in the valve gap rise, the stuffing box gland that is enclosed within valve rod is also along with rising, stuffing box gland just is separated with the blind hole bottom of valve body upper end like this, two through holes on the blind hole bottom are opened simultaneously, so tap water is just from the water inlet, through behind that bottom through-hole that communicates with it, enter in the blind hole of valve body upper end, and then entering into the osculum of valve body through another through hole of bottom, water is just emitted.As long as rotate handgrip (perhaps key handgrip) with the hand clockwise direction, valve rod will drive stuffing box gland and move downward, be adjacent to up to the blind hole bottom of stuffing box gland the valve body upper end, so those two through holes on the blind hole bottom are shut again simultaneously, the water inlet of valve body and osculum are all blocked, and accomplish watertight.And valve rod can not contact with water in entire work process all the time, guarantees that valve rod is lost by scale never.Water outlet place at valve body is installed in pipe joint, can make the user can connect water pipe easily.

The utility model has following advantage compared to existing technology: this water faucet structure is simple, volume is little, can save a large amount of raw material, and cost is low. Seal solid and reliablely, do not metal run out, do not emit water, do not drip. Its valve rod does not contact with water all the time, can prolong the service life of this water nozzle. Take over simultaneously water nozzle and also can do the elbow valve use of 90 degree. Be with the key handgrip, can also prevent that others from will leaving about water, reaches the purpose of saving.
