Abstract
The utility model relates to a water-pressure self-locked type water tap. The utility model is characterized in that a tap body (1) is provided. The upper portion of the water outlet of the tap body (1) is provided with a hollow rotation knob cavity whose one side is a hollow pipe-shaped body. The outer end of the pipe-shaped body is provided with a water inlet. The inner portion of the hollow rotation knob cavity is provided with a rotation knob (5) with an eccentric top wheel which is provided with a hollow path. The rotation knob (5) is fixed on the tap body (1) by an axle sleeve (4) and the hollow rotation knob cavity is sealed. The portion of the hollow pipe-shaped body close to a middle section is provided with a piston cavity whose inner diameter is larger than the water inlet. The inner portion of the piston cavity is provided with a piston (2) which is a hollow cylinder. One end of the hollow cylinder is provided with a bottom. The diameter of the bottom is bigger than the bottom of the cylinder but smaller than the water inlet of the tap body (1). The diameter of the cylinder of the piston is in sliding cooperation with the pipe-shaped body. The inner side of the convex lip edge of the bottom of the piston is provided with a sealing ring. The wall of the cylinder is provided with a through hole.
Description
The utility model relates to the water tap of water system.
At present, the water tap style that water system is used is more, and the water tap of the family expenses of general traditional type is to oppress rubber water sealing below it to shut the water intake in the imperial body by turn-knob, reaches the purpose of Guan Shui.It is cheap, easy to use that rubber water sealing is worth, but because general imperial body mostly is cast iron, and in repeatedly repeatedly under the effect of turn-knob, rubber water sealing weares and teares easily, causes tap to close dead and leak.
The purpose of this utility model provides the water tap that a kind of turn-knob does not act on rubber water sealing, and it is more convenient to make it the water tap use, and long service life, with low cost.
Technical solution of the present utility model is to comprise water intake, water outlet, particularly the utility model has an imperial body, above imperial body water outlet, be the turn-knob cavity, turn-knob cavity one side is a hollow tubular body, there is water intake the tubular body outer end, the knob that the eccentric top of a band wheel is arranged in the turn-knob cavity, eccentric top wheel has hollow passageway, an axle sleeve is arranged, axle sleeve is fixed in turn-knob on the imperial body and closes the turn-knob cavity, and there is a piston cavity that internal diameter is bigger than water intake the nearly middle section of hollow tubular body, and piston is arranged in the piston cavity, piston is the cylinder that an end has the hollow at the end, its end diameter is bigger than cylinder, but less than imperial body water intake, piston cylinder diameter and tubular body are slidingly fitted, the inboard, lip limit of the protrusion at the bottom of piston is fixed with seal ring, and the through hole that is not less than cylinder endoporus area is arranged on the cylindrical wall.
Working principle of the present utility model is that seal ring is enclosed within on the piston, and the piston mouth to living in the mouth of a river, is put into the through piston cavity of imperial body by water intake, thereafter turn-knob is put into the turn-knob cavity, is inserted in turn-knob and is fixed on the imperial body with axle sleeve, just becomes a water tap.Be that the water tap water intake is connected the water source during use, at the eccentric top of turn-knob wheel during,, press Yu Longti until seal ring and go up and block the water route, reach the purpose of closing the water source because the pressure of water forces piston forward to move back to piston.As with turn-knob Rotate 180 degree, eccentric top wheel is over against piston and force piston to be drawn back, and seal ring is also drawn back thereupon, and water promptly enters piston cylinder by the through hole on the piston, and the hollow passageway through off-centre top wheel flows out to water outlet again.Regulating water flow also is that water is promptly ascending with the slowly rotation of turn-knob from 0 to 180 degree, is fit to and ends.
The utility model has the advantages that because seal ring only bears the waterpower hydrostatic pressure of a direction, and be not subjected to the overburdening effect of external force, so it is not easy to wear and reach durable purpose, spend in 180 degree scopes 0 and to rotate turn-knob, be the switch and the flow size of may command water, use condition left-handed, dextrorotation is identical, so made things convenient for use.When closing, the hydraulic pressure more greatly pressure to seal ring is just bigger, so water tap can not leak, during unlatching, current are in straight-through from stream mode, so but also conducting when hydraulic pressure is very low, and because of simple in structure, sturdy and durable, with low cost, replacing is easy to use.
Below in conjunction with accompanying drawing embodiment of the present utility model is described:
Fig. 1, organigram of the present utility model.
According to shown in Figure 1, the utility model has imperial body (1), in imperial body (1) water outlet top is the turn-knob cavity, turn-knob cavity one side is a hollow tubular body, there is water intake the tubular body outer end, the turn-knob (5) that the eccentric top of a band wheel is arranged in the turn-knob cavity, eccentric top wheel has hollow passageway, an axle sleeve (4) is arranged, axle sleeve (4) is fixed in imperial body (1) with turn-knob (5) and goes up and close the turn-knob cavity, there is a piston cavity that internal diameter is bigger than water intake the nearly middle section of hollow tubular body, piston (2) is arranged in the piston cavity, piston (2) is the cylinder that an end has the hollow at the end, and its end diameter is bigger than cylinder, but less than imperial body (1) water intake, piston cylinder diameter and tubular body are slidingly matched, the inboard, lip limit of the protrusion at the bottom of piston is fixed with seal ring (3), and four rectangular through holes are arranged on the cylindrical wall, and the drum diameter of piston (2) is consistent with the thickness of turn-knob (5) top wheel.
