CN2186830Y - Automatic safety faucet - Google Patents

Abstract

The utility model discloses an automatic safety faucet, which is composed of a faucet body, an upper body cover, a lower body cover, a self-closing valve at the time of cutting off the water supply, and a manual water valve. The manual valve is composed of a tailor-made core and a rotary handle; the self-closing valve at the time of cutting off the water supply is composed of a cock body, a rubber cover body, a rubber pad, a distance limiting spacing sheet, and a spring and is fixed on the lower body cover of the automatic safety faucet. The utility model is mainly characterized in that the automatic safety faucet organically integrates the self-closing valve at the time of cutting off the water supply and the manual valve together. When the water supply volume is controlled by adjusting the rotary handle of the manual valve, the action that the opening and the closure of the self-closing valve at the time of cutting off the water supply are control can be played. The utility model has the advantages of simple operation, reliable performance, and long service life.

Description

Automatic safety faucet

The utility model relates to the hardware class, a kind of automatic safety water nozzle.

In the daily life, after cutting off the water suddenly the phenomenon of water happen occasionally, often the carelessness owing to people causes metalling run out, and has not only caused the waste of tap water, returns family's property and brings loss, in case water power mixes mutually, consequence is hardly imaginable.Once had some dissimilar water-stopping self-closing valves to come out before, but still have some shortcomings: self closing stop valve and manually fail to organically combine with water valve can not reach mutual interlock; Self closing stop valve can self-closingly can not leave certainly, behind the water-stopping self-closing, must carry out push-and-pull operation ability breakdown separately, uses very loaded down with trivial details; Self-closing structural design is perfect not to the utmost, and working life is short; The self closing stop valve that has need be added in common water nozzle front portion separately, and cost is higher, and profile is not attractive in appearance.

The purpose of this utility model provides a kind of self-closing valve under water-supply off and manually organically combines all-in-one-piece automatic safety water nozzle with water valve.

The utility model is by faucet body 1, upper body lid 2, lower body lid 3, self-closing valve under water-supply off and manually form with water valve, and manually operated valve is made of fuse 4 and swing handle 12, and fuse 4 is that cross piston body 5 puts inverted concave rubber cushion 6; Self-closing valve under water-supply off is by being with glue lid 8, downward semilune rubber cushion 9, range line partition 10 and the spring 11 of concave surface on cock body 7 bars successively, be fixed to again on the lower cover 3 of water nozzle, the last area of a circle of glue lid 8 and the aspect ratio of glue lid 8 greater than slit around 2.5mm, circle edge and the lower body lid 3 less than 1.5mm, when manually operated valve cut out, the lower end of piston body 5 contacted with 8 of the glue lids at cock body 7 tops.

The utility model main feature is to make self-closing valve under water-supply off and manually combine with water valve, by adjusting the manually operated valve swing handle, promptly plays the breakdown effect of control self-closing valve under water-supply off in the time of the control water consumption, its profile is similar to common water nozzle, can directly install and use, reliable performance, the life-span is long.

Further specify below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model, among the figure, and 1 faucet body, 2 upper bodies lid, 3 lower bodies lid, 4 fuses, 5 piston bodies, 6 rubber cushions, 7 cock bodys, 8 glue lids, 9 rubber cushions, 10 range line partitions, 11 springs.During the water channel normal water supply, self-closing valve under water-supply off is pressed to the below under hydraulic action, and water nozzle is unblocked; When water channel was cut off the water suddenly, bullet on the spring 11 made the glue lid 8 at cock body 7 tops that the water nozzle outlet passage is blocked, and at this moment, opened or closed condition no matter manually operated valve is in, and when coming water again, " metalling run out " phenomenon will not occur.In fact, when the swing handle 12 of manually operated valve revolves for opening state, come water again after, self closing stop valve integral body can not fall, so exhalant canal is choke-out, water can not flow out; When the swing handle 12 of manually operated valve revolves for closed condition, the lower end of the piston body 5 of fuse 4 contacts for point with glue lid 8, only a slit has created condition just for hydraulic pressure breakdown self closing stop valve, self closing stop valve integral body moves down, water channel is unobstructed, but, can not metal run out this practical automatic safety function that just reached naturally because of manually operated valve cuts out.

Claims (2)

1, a kind of by faucet body (1), upper body lid (2), lower body lid (3), self-closing valve under water-supply off and the manual automatic safety water nozzle of forming with water valve, it is characterized in that: manually operated valve is made of fuse (4) and swing handle (12), and fuse (4) is that cross piston body (5) puts inverted concave rubber cushion (6); Self-closing valve under water-supply off is by being with glue lid (8), downward semilune rubber cushion (9), range line partition (10) and the spring (11) of concave surface on cock body (7) bar successively, be fixed to again on the lower body lid (3) of water nozzle, when manually operated valve cut out, the lower end of piston body (5) contacted with glue lid (8) point.

2, automatic safety water nozzle as claimed in claim 1 is characterized in that: the last area of a circle of the glue lid (8) of self-closing valve under water-supply off and the aspect ratio of glue lid (8) are greater than 2.5mm, and the slit is less than 1.5mm around circle edge and the lower body lid (3).
