Abstract
The utility model relates to a running water valve, in particular to a self-closing automatic closing valve for water when the valve is not closed after water is stopped. The valve is composed of a valve cavity, a seal chassis, a bob and a reset push button. One bob is arranged in the cavity, and the seal chassis which is corresponding to the bob is arranged on the lower part of the cavity. A water supply bypass is aranged on the seal chassis which is provided with a reset push button. When the automatic closing valve for water is used normally, the bob floats on the top of the valve cavity, (in the course of useing water, the bob wanders at the water inlet. ). After water is stopped, if the valve is not closed, the bob falls down naturally to seal the opening of the seal chassis, so water cannot drop off when water flows. When water is used, the valve needs to be clseded and the reset push button needs to be pressed. A moment later, the bob resets automatically. So the normal use can be recoverd. Compared with the prior art, the valve can realize the clogging and resetting by the bob and the hydraulic pressure. So the automatic closing valve for water has the advantages of simple and compace structure, flexible and convenience resetting, small volume and low cost of manufacture.
Description
Technical field: the utility model relates to running water valve, the Automatic Closing-water Valve that can close automatically when forgetting closing valve after particularly cutting off the water.
Background technique:
Knownly be used for tap water pipe line automatic shutoff valve door, though of a great variety, its plugging mechanism adopts the structure of similar float substantially, mechanical return, and its complex structure, valve volume is big, the manufacture cost height.
Summary of the invention:
The purpose of this utility model provide a kind of single float rely on the hydraulic pressure shutoff fully and reset, Automatic Closing-water Valve simple in structure, flexible and convenient to use.
The technological scheme that realizes foregoing invention is: this valve is made up of valve pocket, water shutoff base, float, reset button.Establish a float in the chamber, the water shutoff base corresponding with this float is equipped with in the bottom, and the water shutoff base is provided with feed water by-pass, and this feed water by-pass is equipped with reset button.The Automatic Closing-water Valve that realizes according to this technological scheme compared with prior art, because of its shutoff and reset components only have one of float, and relies on hydraulic pressure to realize that so simple in structure, it is flexible to reset fully, the valve body structure compactness, and volume is little, low cost of manufacture.
Description of drawings:
Fig. 1 is a principle schematic of the present utility model.
Embodiment: provide specific embodiment of the utility model below in conjunction with accompanying drawing.The described Automatic Closing-water Valve of this embodiment is by water intake 1, valve pocket 2, and valve 3, water outlet 4, water shutoff base 5, feed water by-pass 6, reset button 7, float 8 is formed.
The working principle of this safety type running water valve is as follows:
During normal the use: because buoyancy of water, float 8 will be in the top of valve pocket 2.Can not fall in the water utilizing process, because according to the pressure characteristics of fluid, the flow velocity of water intake 1 place's water is big, pressure is little, so float 8 will move about around valve pocket 2 top water intakes yet.
The back cuts off the water: if valve 3 is not closed, the water in the valve pocket 2 will all flow out, and float 8 falls naturally, seals water shutoff base mouth 5.Float 8 upper portion pressurized power are very big when coming water, and the bottom only is subjected to atmospheric pressure, so float 8 upper and lower pressure differences are bigger, will seal water shutoff base mouth 5 inflexibly water is closed, to realize the security insurance effect.
Recover to use: after coming water, if valve 3 is in open mode, as mentioned above, then float 8 will be sealed water shutoff base mouth 5 automatically water will be closed.During water, only need valve 3 is closed, press reset button 7 for a moment, water just flows into float 8 bottoms, and float 8 upward pressures float to the top of valve pocket 2 float 8 greater than down pressure at this moment, then recover normal and use.Come to be in closed condition as if valve 3 behind the water, then normally use.
