Abstract

The invention discloses a water tap and belongs to the field of hardware, mainly to solve the problems that conventional water tap leaks water easily. The water tap comprises a valve body, a valve seat, a valve clack, a valve rod, a flywheel and a valve core; the valve rod is screwed on the valve cover by a trapezoidal thread; the flywheel is fixed to the upper end of the valve rod; the valve clack is positioned at the lower end of the valve rod; the valve seat is positioned on the valve body; the valve clack is driven by the valve rod to lift; and the valve clack and the valve seat are clutched, so that the water tap can be opened and closed. The water tap is characterized in that a spring is fixedly arranged on the valve clack; the spring is arranged on the valve body in a sleeving manner; and the end part of the spring is rotatably fixed on the valve rod. According to the water tap, when the valve clack and the valve seat are abraded to produce gaps, the gaps can be automatically compensated due to the elasticity of the spring, so that the water tap can be prevented from leaking water.

Description

A kind of water tap

Technical field

The present invention relates to the hardware article field, specifically a kind of water tap.

Background technique

Present water tap on the market is a lot, wherein the most common, also the most traditional a kind of water tap is: it is mainly by valve body, valve seat, flap, valve rod, handwheel and valve gap form, valve seat is on valve body, detachably, valve rod is screwed on the valve gap with trapezoidal thread, handwheel and flap are fixed on the up and down two ends of valve rod, rotate handwheel, valve rod can rise or land, and drives flap and moves up and down, the clutch of flap and valve seat, water tap is opened and closed, and flap can match closely with valve seat, leans on the pressure of valve rod that flap is pressed on the valve seat, at this moment water tap is in buttoned-up status, and water tap does not tightly leak.But this water tap has quick abrasion, short-life shortcoming, grown service time, flap, valve seat all can wear and tear, make the connecting part of flap and valve seat produce the slit, thereby make water tap produce water clock, will not cause water resource waste if do not change, if change then for the larger unit of the use amounts such as factory, school, replacement cost is very high.

Summary of the invention

The object of the present invention is to provide a kind of water tap, this water tap has the characteristics in the slit between auto-compensation flap and the valve seat.

The present invention solves the technological scheme that its technical problem takes: a kind of water tap, comprise valve body, valve seat, flap, valve rod, handwheel and valve gap, valve rod is twisted with trapezoidal thread and is spun on the valve gap, handwheel is fixed on the upper end of valve rod, flap is positioned at the lower end of valve rod, valve seat is positioned on the valve body, valve rod drives flap and moves up and down, the clutch of flap and valve seat, water tap is opened and closed, it is characterized in that, be installed with spring on the described flap, described spring is nested with on the described valve rod and its end and rotatably is fixed on the described valve rod.

Described valve rod is provided with a circle groove, and described spring top is provided with jump ring, and described jump ring is stuck in the described groove.

Described flap upper surface is provided with blind hole, and described blind hole upper end inwardly bending makes the diameter of blind hole upper end less than the diameter of blind hole, and its end made its end diameter greater than the diameter of described blind hole upper end along circumferentially extending after described blind hole was inserted in described valve rod lower end.

The invention has the beneficial effects as follows: owing to being provided with spring, between flap and valve seat, produced the slit, and handwheel has been screwed in the time of can not twisting again, at this moment because the elastic force of spring moves downward flap automatically, fill up because the slit that the wearing and tearing of flap and valve seat cause, thereby reach the purpose that water tap is not revealed.

Description of drawings

Fig. 1 is sectional drawing of the present invention;

Fig. 2 is the enlarged view of A among Fig. 1;

Among the figure: 1 valve body, 2 valve seats, 3 flaps, 4 valve rods, 5 handwheels, 6 valve gaps, 7 springs, 8 grooves, 9 jump rings, 10 blind holes, 11 sealing gaskets.

Embodiment

Such as Fig. 1, shown in Figure 2, water tap of the present invention, comprise valve body 1, valve seat 2, flap 3, valve rod 4, handwheel 5 and valve gap 6, valve rod 4 usefulness trapezoidal threads are twisted and are spun on the valve gap 6, be provided with sealing gasket 11 between valve body and the valve gap, handwheel 5 is fixed on the upper end of valve rod 4, flap 3 is positioned at the lower end of valve rod 4, with valve rod 4 splits design, be fixedly provided with spring 7 on the flap 3, spring 7 is nested with on the valve rod 4 and its end and rotatably is fixed on the valve rod 4, valve seat 2 is positioned on the valve body 1, revolve handwheel 5 valve rod 4 is moved up and down by twisting, the elevating movement of valve rod 4 drives flaps 3 by spring 7 again and does elevating movement, and the impulse force of water also helps flap 3 to do motion upwards simultaneously; The clutch of flap 3 and valve seat 2 opens and closes water tap.

Valve rod 4 can be such with being connected of spring 7: at valve rod 4 a circle groove 8 is set, the top of spring 7 arranges a jump ring 9, and jump ring 9 is stuck in the groove 8, rotates thereby the position of spring 7 on valve rod 4 fixed relatively and can be centered on valve rod 4.

For driving flap 3, the valve rod 4 of being more convenient for does motion upwards, upper surface at flap 3 is provided with blind hole 10, the inside bending in blind hole 10 upper ends makes the diameter of blind hole 10 upper ends less than the diameter of blind hole 10, its end made its end diameter greater than the diameter of described blind hole 10 upper ends along circumferentially extending after blind hole 10 was inserted in valve rod 4 lower ends, in the raw the time, the underpart of valve rod 4 contacts as good with the top of blind hole 10 length of valve rod 4 in his blind hole 10 with spring 7.When handwheel 5 band ovable valve stems 4 move downward, flap 3 passes under the effect of the pressure of coming by spring 7 at self gravitation and valve rod 4, the impulse force that overcomes water moves downward, when flap 3 moves to when contacting with valve seat 2, continue to twist and revolve handwheel 5, after spring 7 is squeezed extruding force passed to flap 3, flap 3 and valve seat 2 are closely cooperated, current are blocked, at this moment between flap 3 and the valve seat 2 because slit that wearing and tearing produce also can be remedied by the elastic reaction of spring 7, and water clock can not occur; When twisting when revolving handwheel 5 and moving upward, flap 3 is subject to the impulse force of water on the one hand, and flap 3 is subject to the pulling force of spring 7 and valve rod 4 on the other hand, makes that flap 3 is easier to be separated with valve seat 2.

Except the described technical characteristics of specification, be the known technology of those skilled in the art.
