CN2344610Y - Diaphragm cutting-off type tap - Google Patents

Abstract

The utility model relates to a diaphragm cut-off type water tap. The utility model is mainly formed by that a water inlet pipe arranged on a valve body extends into the middle part of an inner cavity of the valve body, and a water inlet is arranged in a position which is corresponding to an end plug; the inner cavity of the valve body is communicated with a water outlet pipe; a diaphragm is changed from plugging a water outlet into plugging a water inlet. The water tap can be opened while pulling force is not applied to the diaphragm so that the simple structure. When the water tap is closed, the inner cavity of the valve body has no ponding, and the diaphragm is changed into a corrugated structure. The utility model has the advantages of no leakage, no easy frost crack, long service life, etc. The utility model is most suitable for being matched with a washing machine, and the utility model can also be used as an ordinary water tap.

Description

Barrier film cutting type water tap

The utility model relates to a kind of water tap, and the water tap of the effective and long service life of particularly a kind of anti-bursting by freezing belongs to valve field.

Water tap great majority in the market are to adopt the mode of rotary spool to carry out opening and closing, being contained in Sealing on the spool often is rotated friction and causes easily and leak, a kind of water tap of CN2195017 patent disclosure, used barrier film cutting type structure, has the good advantage of anti-leak result, but because this patent is to carry out opening and closing by haling the mode of stretching barrier film shutoff valve body water outlet, barrier film damages in being come and gone the process of turnup easily, because of being arranged, negative pressure produces suction at water outlet, barrier film must need bigger pulling force and overcome this suction and just can make face leave water outlet, in order to make barrier film can bear big pulling force, just barrier film and valve rod front end must be fixedly mounted, as take to have the blind hole of shrinking lip in barrier film interior edge face center portion design, design has the measures such as pillow block of groove on the valve rod front-end face, make its structure comparatively complicated, be water outlet because of what close again, so when closing, also be full of water in the inner chamber of water tap, winter when outdoor application easily by shortcomings such as bursting by freezing.

The purpose of this utility model is in order to overcome above-mentioned deficiency of the prior art, designs a kind of simple in structure, long service life, the anti-effective barrier film cutting type water tap of bursting by freezing.

Barrier film cutting type water tap of the present utility model is on the basis of existing diaphragm type water tap, take to change barrier film measures such as into shutoff water intake by the shutoff water outlet and realize, its structure mainly comprises the valve body that has turnover water pipe and inner chamber, barrier film, plug, stop collar, valve gap, screw rod and handle, wherein, barrier film is corrugated structure, intake pipe on the valve body stretches into the body cavity middle part and has water intake in the position corresponding with plug, body cavity communicates with outlet pipe, its mounting point and annexation are: the plug front end sleeve is at the barrier film middle part, the barrier film outer rim is with on the step of stop collar press seal in valve pocket, the screw rod front portion spins through the inner chamber at screw thread and plug rear portion, the plug outside has two slide blocks to slide up and down in two chutes of stop collar, the valve gap that the screw rod middle part has a circle convex tendon to be fixed on the valve body upper end blocks, and the screw rod upper end is stretched out valve gap and is connected with handle.

Accompanying drawing is a structural representation of the present utility model.

Referring to accompanying drawing, barrier film 11 among the figure is corrugated structure, intake pipe 1 on the valve body 13 stretches into body cavity middle part and has water intake 12 in the position corresponding with plug 10, body cavity communicates with outlet pipe 14, plug 10 front end sleeves are at barrier film 11 middle parts, the barrier film outer rim uses stop collar 2 press seals on the step of body cavity, screw rod 5 front portions spin through the inner chamber at screw thread and plug rear portion, the plug outside has two slide blocks 9 to slide in two chutes 3 on stop collar 2, screw rod 5 middle parts have a circle convex tendon 8 to be blocked by the valve gap 4 of valve body 14 upper ends, the upper end of screw rod 5 is stretched out valve gap 4 and is fixedlyed connected with handle 6, the spacing shoulder 7 of handle 6 is pressed against on the valve gap 4, screw rod 5 can only be rotated, and plug can only slide up and down, so rotatable handle can make plug slide up and down, plug makes membrane cover live in the mouth of a river to lower slider, and water tap promptly is closed; Plug upwards slides, and barrier film can be followed plug automatically because of the pressure of water and be moved up, and water tap promptly is unlocked.In order to make water can flow to the middle part, pond, intake pipe on the valve body and outlet pipe can be the angle of inclination design, its angle of inclination should be elected the 95-120 degree as, and best angle is the 100-110 degree.For the ease of maintenance, can be with being threaded between valve gap and valve body, for the reduction expense, all can be made of plastic except the corrugated barrier film made from rubber in these leading component.Because need not that barrier film is applied pulling force just can open water tap, so structure is comparatively simple, does not have ponding because of body cavity when closing again, so be difficult for by bursting by freezing, more, increased the elasticity of barrier film self, prolonged the working life of barrier film because of diaphragm design becomes ripple struction.

Tap of the present utility model has simple in structurely, do not have to leak, and is difficult for by bursting by freezing long service life etc. Advantage, the most suitable and Washing machine matched uses, and also is fit to do ordinary faucet and uses.
