Abstract
The utility model relates to an automatic cut-off device used for tap water pipelines. The utility model can automatically close the pipeline when the pipeline has water break and has water again. The utility model comprises a casing body which is provided with a water inlet pipe opening and a water outlet pipe opening which are communicated with each other. The interior a hole cavity of the casing body is provided with a control valve which can move up and down, and the control valve is composed of a plunger and a control sealing pad positioned on the top of the casing body which are connected together. The control sealing pad is composed of a rubber pad and a spring. The top of the casing body is provided with a cosmetic hood connected with the control sealing pad, and the control valve is sealed in the hole cavity of the casing body by a press cap.
Description
The utility model relates to a kind of pipeline water closing device, especially relates to a kind of automatic water turn-off device that is used for tap water pipe line.
In the background technique, the water closing device that existing tap water pipe line is adopted is water tap and stop valve, the switching of pipeline when water tap or stop valve can only be used to water is arranged, and run into when cutting off the water, if water tap do not close, meet pipeline again when coming water, because water tap does not have self-closing function, as unmanned on the scene, then tap water can be lost in vain, causes very big waste, and tap water also can diffuse out outside the pond sometimes, make ground be flooded, cause bigger loss.
The purpose of this utility model has been to overcome the deficiency in the above-mentioned background technology, and a kind of automatic water turn-off device is provided, and it can be cut off the water supply at pipeline and blind off a line automatically when coming water again.
For achieving the above object, the technical solution that the utility model adopts is as follows:
A kind of automatic water turn-off device, its special way is: comprise housing, housing is provided with water inlet pipe mouth and the effluent pipe mouth that is connected, and is provided with the control valve that can move up and down in the housing vestibule, and control valve is connected and composed by plunger and the control sealing gasket that is positioned at case top;
Above-mentioned control sealing gasket can be made of rubber seal and spring;
Above-mentioned case top can be provided with and control the cosmetic cover that sealing gasket links to each other;
Above-mentioned control valve can be sealed in the housing vestibule with pressure cap;
Above-mentioned plunger can be connected with bolt between the sealing gasket with control.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the user mode figure of the utility model in pipeline.
Number in the figure is described as follows:
1-housing, 2-plunger, the 3-cover of making up, the 4-connecting bolt, the 5-pressure cap, 6-controls sealing gasket.
Below in conjunction with accompanying drawing the utility model is described in further detail: referring to Fig. 1, Fig. 2, comprise housing 1, housing 1 is provided with water inlet pipe mouth and the effluent pipe mouth that is connected, and water inlet pipe mouth is connected with pipeline, and effluent pipe mouth is communicated with water tap.Be provided with the control valve that can move up and down in housing 1 vestibule, control valve be sealed in the housing 1 with pressure cap 5.Control valve is connected and composed by plunger 2 and the control sealing gasket 6 that is positioned at case top, connects with bolt between plunger 2 and the control sealing gasket 6, and control sealing gasket 6 is made up of rubber seal and position spring thereon, controls sealing gasket and is provided with coupled cosmetic cover.During actual the use, earlier this automatic water turn-off device and pipeline and water tap are connected, upwards gently mention the cover 3 of making up, control valve is moved up, connect intake pipe and outlet pipe, make water flow to water tap by this device, because the buoyancy of water effect, it is constant to make that the control valve position remains.Like this, under the situation that water is normally arranged, no matter water tap is opened or is closed, and this device all is in " often opening " working state, need not operation bidirectional.In the using process, regulating water-quantity and open and close water are still controlled with water tap.If water pipe comes water to interrupt, because buoyancy of water disappears, control valve moves down under gravity and spring force effect, embeds in the housing, makes between intake pipe and the outlet pipe to disconnect.When coming water again, the active force of water is only to the generation effect of control valve side, and control valve is upwards floated.Like this, control valve will be closed water automatically and will be in " normally closed " working state all the time, and when coming water again, water will be blocked before water tap, can not cause running water because of forgetting to turn off the tap.As the normal water of need, need only make progress and gently mentioning the cover of making up and get final product.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, the utility model can be cut off the water supply when water pipe line is anhydrous automatically fully, has stopped because of running water Cut off the water when coming water again because the waste of the water that causes of forgetting to turn off the tap, and the house property that water logging causes decreases Lose;
2, the normal use of the utility model need not operation bidirectional, and regulating pondage and open and close water are still used tap Control. In addition, the utility model volume is small and exquisite, installation and easy to use;
3, the utility model non-transformer and machine driving can not cause stuck malfunctioning;
4, the utility model adopts fine ceramic to make encapsulant, and is wear-resistant, indeformable, non-corroding;
5, the utility model is suitable for the water temperature wide ranges, also can be installed in to replace stop valve to make on the tap water pipe line With.
