Abstract

The utility model provides an overflow preventing and water saving device. The utility model comprises a main housing, a water inlet, a water outlet, a ball float which acts as a valve core, an upper cover, a lower cover and a button device for opening and closing. Due to the principle of the buoyancy of the ball float and the principle of water pressure difference, a water tap can be automatically closed for water supply when water is cut off, so when the water is supplied again, the phenomenon of water overflow for the water tap which is opened does not occur. The utility model can also act as a valve when a water supply system is closed during the water supply. The utility model has the advantages of simple structure, low manufacturing cost, convenient control for opening and closing, water overflowing prevention, water saving, etc., and can be widely used in various water supply systems in families, institutions, enterprises and institutions, public places, etc.

Description

The anti-overflow water economizer

The utility model belongs to a kind of pipe fitting, specially refers to the water economizer that the anti-sealing in the water system overflows from tap.

In existing most of supply channels, water tap or valve are only arranged, people usually fetch boiling water tap or valve and do not close when cutting off the water, thereby metal run out, the spilling water phenomenon, and particularly spilling water often takes place in public places, causes a large amount of wastes of water.Chinese patent ZL90223558 discloses a kind of water economizer, and it is by setting sleeve, and pressure spring, dish three parts of damming are formed.It utilizes the flowing water gland to control and closes, and when current were big in use, water economizer was also closed water system automatically, brings unnecessary trouble to the user.

The utility model provides a kind of working principle simple, is not subjected to the restriction of current size, closes water supply automatically when stopping to supply water, and controls the anti-overflow water economizer that supplies water easily.

A kind of anti-overflow water economizer that the utility model provides, it comprises main casing, water inlet on the main casing and water outlet, the spool of main casing inner chamber and top cover, its characteristics are that the spool in the inner chamber of described main casing is a ball float, and main casing has two lids, i.e. top cover and bottom up and down.The inner chamber of main casing is divided into two cavitys up and down, and a sealing surface that matches with ball float is arranged between two cavitys, and a water inlet is arranged on upper cavity, and a water outlet is arranged on lower chamber.Ball float has one to have releasing the button of spring at the center of bottom in upper cavity, spring be contained in release the button and bottom between, release the button and bottom between seal ring is arranged.

The enforcement of the anti-overflow water economizer that provides by the utility model, its working principle is simple and practical, is not subjected to the restriction of current size, closes water supply when cutting off the water automatically, the water tap phenomenon of under the excessive state of opening, metalling run out when having prevented to supply water again, thus reached water-saving purpose.And can control easily to start and supply water.

Description of drawings:

Fig. 1 is the structure principle chart of anti-overflow water economizer.

Fig. 2 has the anti-overflow water economizer structure principle chart that opens and closes function.

Below in conjunction with accompanying drawing, describe representative instance of the present utility model in detail.

Fig. 1 is the basic structure of anti-overflow water economizer, ball float 4, upper top cover 5 and the bottom 6 that it comprises main casing 1, water inlet 2, water outlet 3, use as spool, release the button 11, spring 10 and seal ring 12.Main casing has two lids up and down, its inner chamber has a upper cavity 7 and lower chamber 8, the internal diameter of upper cavity is greater than the internal diameter of lower chamber, a water inlet is arranged on the upper cavity, a water outlet is arranged on the lower chamber, a sealing surface 9 that cooperates ball float is arranged between two chambeies, releasing the button of a band Returnning spring is housed at the center of lower bottom cover, spring be contained in release the button with bottom in the middle of, release the button and bottom between seal ring is housed.

Fig. 2 has the bifunctional anti-overflow water economizer structure of switching, and it has increased the locational seal ring 13 between upper and lower cavity on the structural principle of Fig. 1, be fixed with a support 14 in upper cavity with on the top cover.In addition, an X button 15 that is used for closing water also is housed in top cover in the heart, a Returnning spring 16 is housed between top cover and the X button, and is linked together with the X button termination above the support 14, and a plurality of rectangular holes are arranged on the cone of said support 14 or make netted.

Ball float, support and seal ring can be used non-toxic plastic, ball float, seal ring, also optional nontoxic rubber, and the proportion of ball float should be less than water.Its upper cavity internal surface and sealing surface should be smooth.

Working principle of the present utility model, in the pipeline of normal water supply, when not cutting off the water, because of ball float proportion less than water, so ball float is in cavity top, water can be flowed out by water outlet through cavity from water inlet, Flat valve core is in opening state, and when cutting off the water, water tap is in closed condition, still have water in the cavity this moment, ball float descends but can not close water supply, and if water tap is not closed for some reason, open mode, stop owing to supplying water this moment, the water of upper and lower cavity all can be drained, and ball float falls naturally, and tight contact is put in ball float sealing surface or sealing, two chambeies isolation up and down, the blocking-up water route.When coming water, by fills with water, be subjected to the blocking-up of ball float in the upper cavity, there is not water in the lower chamber, although water tap is opened, still can avoid water to overflow from water tap.Suffered deadweight of ball float this moment and upper cavity water are to the pressure of ball float, and it can not float.

When people need water, release the button as long as click with hand, ball float will on float to the upper cavity top, enter the water supply state.

Water tap or water tap are out of control when changing, and in the time of need stopping to supply water, as long as click X button with hand, (water tap opening state) pushes ball float to sealing surface or seal ring place, and ball float is under the pressure of epicoele water, and the effect of valve can be played in the blocking-up water route.

The utility model also can be combined into the composite water-saving water tap with water tap.

The utility model can be widely used in the water system, is applicable to that particularly family supplies water, in the water pipeline of public place.Have low cost of manufacture, easy to use, advantages such as using water wisely.
