Abstract
The utility model discloses a self-closing valve when water supply is cut off, which comprises a shell body and a self-closing device, wherein, the self-closing device comprises a shell cover, a piston, a piston sleeve, a spring, a connecting rod pin and a slide groove; one end of a shell body of the self-closing device is provided with a convex block connected with a water outlet pipe; the piston sleeve is fixed in the shell body through screws in the connecting mode; the spring and the piston are arranged in the piston sleeve; the piston is arranged at the upper part of the spring; the piston is provided with the slide groove for the connecting rod pin to be connect with and to slide in; one end of the shell cover is fixedly connected with the shell body by bolts, and the other end is connected with the water inlet pipe. The utility model provides valve which can automatically close when the water supply is cut off and can automatically open when the water supply is given. The self-closing valve when water supply is cut off has the advantages of simple and reasonable structural design, convenient use, convenient assembly and disassembly and no need of an external energy source.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of valve of closing automatically after cutting off the water.
Background technique
At present, known valve kind is more, and structure is different, closes the principle of cutting off the water supply and is the people and combine with mechanical property and finish, and its defective is the transmission part complex structure, and rust is dead easily, and the time has been grown transmission part and just quit work.
In the middle of daily life, people can forget phenomenons such as Guan Shui, turn out the gas, easily cause unnecessary waste and gas leakage accident, for this reason, people design and have produced some self-closing devices, existing self-closing device needs electricity consumption or battery to finish, when have a power failure or battery cause after using up can not automatic-closing valve.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provide a kind of when cutting off the water, forget close and the valve of opening automatically when coming water.This valve mechanism is reasonable in design simple, easy to use, the throttle down of cutting off the water automatically that does not need the outer energy of easy accessibility.
A kind of water-stopping self-closing valve of the present utility model, comprise housing, self-closing device, its self-closing device is made of cap, piston, piston sleeve, spring, link pin and sliding-groove, housing one end at self-closing device is provided with the projection that connects with outlet pipe, piston sleeve is screwed and is connected in the housing, spring and piston are housed in the piston sleeve, piston is on the top of spring, have the sliding-groove that connects and slide for link pin on the piston, cap one end is fixedly connected with housing with bolt, and the other end connects with intake pipe.
Described self-closing valve, the top of the sliding-groove on the piston are provided with free position, and the bottom is provided with obstruction.
Described self-closing valve, the projection on the self-closing device designs for one with housing, establishes internal thread in the projection, and the projection diameter is adaptive with the pipe diameter that connects.
Described self-closing valve, seal ring also can be put in each joint of self-closing device.
Valve of the present utility model does not need that external force is auxiliary can finish automatic-closing valve, and is simple in structure, easy to use, easy accessibility, and reduced the waste of water resource.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. housing 2. caps 3. pistons 4. piston sleeves 5. springs 6. link pins 7. projections 8. sliding-grooves 9. bolts 10. screws
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
See also shown in Figure 1, water-stopping self-closing valve of the present utility model, by housing 1, cap 2, piston 3, piston sleeve 4, spring 5, link pin 6, projection 7 and sliding-groove 8 constitute, housing 1 one ends are provided with the projection 7 that connects with outlet pipe, be provided with internal thread in the projection 7, the size of projection 7 is big or small adaptive with pipeline, projection 7 is an one with housing 1, piston sleeve 4 usefulness screws 10 are fixedly connected in the housing 1, spring 5 and piston 3 are housed in the piston sleeve 4, and piston 3 has the sliding-groove 8 that connects and slide for link pin 6 on the top of spring 5 on the piston 3, cap 2 one ends are fixedly connected with housing 1 with bolt 9, and the other end connects with intake pipe.In order to make the good sealing effect of this valve, can put into seal ring in each joint.
During use, this valve one end is connected on the ordinary tap water pipeline, the other end connects an ordinary faucet, when normal water supply, because the pressure piston 3 of water is depressed, at this moment, link pin 6 is on the position, free position, and water can flow through self-closing device smoothly and flow out from water tap.
When cutting off the water, owing to there has not been the pressure of water, piston 3 is boosted by spring 5, and link pin 6 is in obstruction, the water supply path blockade.In the process of cutting off the water, do not close if there is the people that water tap is opened, link pin 6 can be locked the obstruction of sliding-groove 8 automatically, and the water supply path remains closes.
When coming water, hydraulic pressure is depressed piston 3, and water just flows out from water tap.
Valve of the present utility model is closed when cutting off the water automatically for making ordinary tap water, design to reach water-saving purpose, each workpiece has reasonable in design, in light weight, easy for installation, use characteristic of simple, be suitable for being installed on the water terminal as water-saving device, as family, office, laboratory etc., in addition, can be used as the liquid transport system parts after this product percent of pass and be extensive use of in the industrial or agricultural field.
