Abstract

Disclosed is a tap joint capable of self closing on water supply stop. In the utility model, a vertical flow channel is arranged, a sliding slot whose least significant end is provided with a tube sinking is arranged, and the sliding slot is communicated with the flow channel; a hollow pontoon in which a lower extending flashboard is arranged; the starting end of the flow passage opening of a valve body on a water outlet side is matched with a ring sleeve type sealing ring; a sidesliping slot wall on a water inlet side is provided with an overflow gutter which is straight communicated with the flow channel, and a sidesliping slot wall on a water outlet side is provided with an overflow pore canal whose outlet is positioned on the flow channel behind the sealing ring. The utility model has the advantages of simple structure which is simpler than that of an ordinary tap capable of self closing on water supply stop and reliable self closing function when water supply is cut off. The utility model has no special requirements on water pressure in a pipe, and an all-purpose tap can be used.

Description

Tap joint capable of self-cut-off on water supply stop

But the utility model provides a kind of water fittings of water-stopping self-closing, is made up of valve body, floating drum, belongs to valve technology field.

Along with the shortage of drinkable water, the number of times of cutting off the water in the daily life will increase gradually.On the other hand, in water utilizing process, often take place but to forget when cutting off the water and close water valve that general the rotting of running water caused disaster when coming water, not only causes very big waste, and brings disaster to neighbours' phenomenon.No. 8620719 patent of China introduced a kind of self-closed water tap that turnover panel and rubber are set in self-closing chamber, the balance of hydraulic head impulse force destruction turnover panel and rubber realizes self-closing when relying on rehydration.This self-closing water tap has self-closing preferably function, but water pressure is required tighter, hydraulic pressure hour, self-closing function is unreliable.The disclosed self-closing water tap of other patent is as patent the 8821039th.The wedge block type self-closing water tap, complex structure, technology difficulty is big.

The utility model is at the deficiency of existing self-closed water tap, provides a kind of when cutting off the water in water supply, closes automatically, and structure is simpler, and water pressure is not had specific (special) requirements, as the water fittings of water lines and water nozzle intermediate connector.

Above-mentioned purpose of the present utility model realizes by taking following technical measures.

Vertical run is set in the valve body, and least significant end has floating drum, the valve body water outlet side runner mouth top of stretching flashboard under the band of configuration hollow in reducing and the chute that communicates with runner, the chute and disposes sleeved seal ring, influent side runner wall and establish the overflow duct that outlet is positioned at runner behind the seal ring is set in the overflow ditch of straight-through runner, the water outlet side runner wall.

During use, but the water fittings level of water-stopping self-closing is connected between water nozzle and the water pipe.When not cutting off the water, floating drum floats, and stretching flashboard leaves seal ring down, and runner is opened, and freely supplies water.When cutting off the water, floating drum is stretched flashboard down and is stopped up the runner seal ring because deadweight is fallen along chute.When resuming water supply, the runner internal water pressure can make flashboard near seal ring.Water pressure is big more, and seal degree is high more, current can be stopped reliably, plays the effect of water-stopping self-closing.At this moment, if water nozzle is in opening state.Then current have a small gangs of to flow into chute along the overflow ditch on the runner wall in the runner, splash into the water outlet side runner along overflow duct in the opposite side runner wall then, flow out through the water nozzle mouth.Prompting has come water, closes water nozzle as early as possible.Because cross section, overflow duct is less, the long period drips and also the water logging phenomenon can not take place.If water nozzle is in closed condition, the water droplet that drips in the overflow duct can be full of the water outlet side runner gradually.Force floating drum come-up in the floating trough at last, runner is unimpeded, can carry out normal water supply.

But the water fittings of water-stopping self-closing, structure is simpler than general self-closed water tap, and the water-stopping self-closing reliable in function does not have specific (special) requirements to hydraulic pressure in the water pipe, and can utilize general water nozzle.

Accompanying drawing is the utility model structural representation, below in conjunction with accompanying drawing, and the technical characteristics of narration most preferred embodiment.

But the water fittings of water-stopping self-closing, by the valve body (1) of the chute that has vertical run (4), band is stretched the floating drum (6) and valve gap (3) composition of flashboard down in the chute.Chute least significant end has reducing (8) and communicates with runner.The influent side runner wall is established the overflow ditch (5) of straight-through runner, and the overflow duct (2) that outlet is positioned at runner behind the seal ring is set in the water outlet side runner wall, and valve body water outlet side runner mouth top disposes sleeved seal ring (9).

In the present embodiment, overflow channel diameter 2-3mm, overflow trench cross section 4-6mm ²Floating drum external diameter 8-12mm, length 18-22mm, the runner wall that is positioned at the floating drum end section is provided with floating drum axle slideway.

But the water fittings of water-stopping self-closing, the main available ABS plastic manufacturing of part.

Claims

But 1, a kind of water fittings of water-stopping self-closing, form by valve body, floating drum, it is characterized in that being provided with in the valve body vertical run, least significant end has floating drum, the valve body water outlet side runner mouth top of stretching flashboard under the band of configuration hollow in reducing and the chute that communicates with runner, the chute and disposes sleeved seal ring, influent side runner wall and establish the overflow duct that outlet is positioned at runner behind the seal ring is set in the overflow ditch of straight-through runner, the water outlet side runner wall.
But 2, the water fittings of water-stopping self-closing according to claim 1 is characterized in that overflow channel diameter 2-3mm, overflow trench cross section 4-6mm ²Floating drum external diameter 8-12mm, length 18-22mm.
But 3, the water fittings of water-stopping self-closing according to claim 1 and 2 is characterized in that the runner wall of floating drum end section is provided with floating drum axle slideway.
