Abstract

The utility model discloses a tap for preventing leakage. The utility model is characterized in that the water inlet end of an ordinary tap is provided with a float chamber, and a ball float is arranged in the float chamber. When water is supplied after water supply is cut off, the ball float and the water outlet of the float chamber realize the functions of automatic closing by means of gravity. The utility model has the advantages of simple structure, low cost, and convenient operation.

Description

Tap

The utility model belongs to valve, relates in particular to a kind of leakage prevention water faucet.

Ordinary faucet forgets when closing after cutting off the water, and comes the phenomenon of often metalling run out behind the water.At present, the self-closing faucet emerge in multitude, but mostly be complex structure, use inconvenience.The purpose of this utility model provides a kind of simple in structure, manufacturing and easy to use, and cheap leakage prevention water faucet.

The utility model is achieved in that at the feed-water end of ordinary faucet ［ 6 ］ establishes a floating chamber ［ 3 ］, adorns a ball float ［ 4 ］ in floating chamber ［ 3 ］, and the diameter of ball float ［ 4 ］ is greater than the water intake diameter, and proportion is less than the proportion of water.The top of ［ 3 ］ also is provided with a bleed valve ［ 2 ］ in the floating chamber, is used for discharging in the floating chamber air and uses.

Because the utility model is simple in structure, just on ordinary faucet, increase a floating chamber, just can finish under the situation of after cutting off the water, not closing water tap, finish self-closing function when coming water.

Accompanying drawing is a structural representation of the present utility model

The 1-float chamber, 2-bleed valve, 3-floating chamber, 4-ball float, 5-exhaust tube.

Now in conjunction with the accompanying drawings embodiment of the present utility model is described further:

The utility model be the feed-water end at existing ordinary faucet ［ 6 ］ be provided with a floating chamber [3 ］, in the floating chamber, be provided with the ganoid ball float of a plastic hollow ［ 4 ］, when tap water was cut off the water supply, ball float ［ 4 ］ will fall into the bottom of floating chamber ［ 3 ］ automatically; When coming water, because generation eddy current gravitation can not float ball float ［ 4 ］ and tightly blocks floating chamber's water outlet between ball float ［ 4 ］ and the floating chamber's water outlet.After this air of inside, floating chamber makes whole floating chamber water-filling by bleed valve ［ 2 ］ and exhaust tube ［ 5 ］ under pressure of supply water.When water, only ordinary faucet ［ 6 ］ need be closed, because eddy current gravitation disappears, ball float ［ 4 ］ will float, thereby makes whole water tap be in normal operating condition.

Claims (2)

1, a kind of leakage prevention water faucet, it is made of valve body, spool, it is characterized in that being provided with a floating chamber [3] in the inlet end of ordinary faucet [6], and a ball float [4] is housed in floating chamber [3], is provided with a bleed valve [2] on the top of floating chamber.

2, leakage prevention water faucet as claimed in claim 1 is characterized in that the proportion of the proportion of ball float ［ 4 ］ less than water.
