Description
Technical Field
The invention relates to an indoor water supply system, in particular to a self-locking valve for water cut-off.
Background
The existing water faucet in a resident home is basically in a traditional mode and only has a simple switching function, if the water faucet is forgotten to be closed due to the fact that a tap water pipeline stops water, once the tap water pipeline supplies water, the water faucet can be discharged endlessly until the water faucet is submerged on the ground and attracts people's attention, and therefore a large amount of tap water is lost.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a self-locking valve for water cut-off, which can realize self-locking when a water tap is forgotten to be closed after water cut-off.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a self-locking valve of cutting off water, includes valve body and delivery port, the delivery port top is equipped with locking device, locking device includes first breakwater and pivot, pivot and first breakwater fixed connection, the pivot rotary type sets up delivery port one side, when anhydrous in the valve body, first baffle can rotate extremely the delivery port seals the delivery port.
In addition, the invention also provides the following auxiliary technical scheme: the locking device further comprises a second water retaining plate, and the second water retaining plate is fixedly connected with the rotating shaft.
The first water baffle is perpendicular to the second water baffle.
The weight of the first water baffle is greater than that of the second water baffle.
The other end of the first water baffle is provided with a magnet, and a corresponding magnetic material is arranged in the valve body.
And a piston is arranged below the water outlet, one end of the piston is positioned in the valve body, and the other end of the piston is positioned outside the valve body.
Compared with the prior art, the invention has the advantages that: when the water supply is cut off, the first water baffle can be inverted to the water outlet, so that the water outlet is closed, the water cannot flow out of the water outlet, water resources are saved, the first water baffle is provided with the magnet and can be adsorbed on the valve body, and even if the water tap is opened during water supply, the water cannot flow out, so that the purpose of self-closing is achieved, and the water supply valve is suitable for being used in families. When water needs to be discharged again, the first water baffle is pushed away from the water outlet through the piston.
Drawings
Fig. 1 is a schematic view of a normal water supply structure of the self-locking valve of the present invention.
FIG. 2 is a schematic view of the water-stop self-locking structure of FIG. 1.
Detailed Description
The present invention will be described in further non-limiting detail with reference to the following preferred embodiments and accompanying drawings.
As shown in fig. 1 and 2, the water-stop self-locking valve comprises a valve body 1, wherein the valve body 1 is provided with a water inlet 2, a water outlet 3 and a locking device 7, the locking device 7 is arranged above the water outlet 3, and when a tap is forgotten to be turned off under the condition of water stop, the locking device 7 can automatically cut off the water flow of the water outlet 3.
The locking device 7 can be rotatably arranged on the water outlet 3, specifically, the locking device 7 comprises a first water baffle 71, a second water baffle 72 and a rotating shaft 73, the first water baffle 71 and the second water baffle 72 are both fixedly connected to the rotating shaft 73, the first water baffle 71 and the second water baffle 72 are vertically arranged, the rotating shaft 73 is rotatably fixed to the corner of the valve body 1, the weight of the first water baffle 71 is higher than that of the second water baffle 72, preferably, the first water baffle 71 and the second water baffle 72 are made of buoyancy materials, when the valve body 1 is filled with water, the first water baffle 71 and the second water baffle 72 have certain buoyancy, and when no water flow acts, the first water baffle 71 is inverted to the water outlet 3.
Still be equipped with baffle 4 in the valve body 1, baffle 4 divide into from closing chamber 5 and diversion chamber 6 with valve body 1, and rivers flow through from closing chamber 5 and diversion chamber 6 and flow into delivery port 3 through water inlet 2, and baffle 4 is located and is equipped with arch 51 from closing chamber 5 one side, makes rivers get into and closes 5 velocity of flow that the velocity of flow is less than the velocity of flow that rivers got into diversion chamber from closing chamber.
The valve body 1 is externally provided with a movable piston 8, and the piston 8 is positioned on one side of the first water baffle 71. The first water baffle 71 has a length larger than the width of the water outlet 3, a magnet 712 is disposed at the end thereof, and a magnetic material is disposed at the contact position of the magnet 712 and the water outlet 3.
The locking device 7 is initially in the state shown in fig. 1, and when water is normally supplied, water flows from the water inlet 2 into the self-closing chamber 5 and the water diversion chamber 6 respectively, and the first water baffle 71 and the second water baffle 72 are subjected to the buoyancy effect, so that the first water baffle 71 cannot fall to the water outlet 3 along the rotating shaft 73, and the water flows out of the water outlet 3. When water is cut off, the water outlet 3 is opened and the water is forgotten to be closed, and because the first water baffle 71 is heavy, when no water exists in the valve body 1, the first water baffle 71 is pressed above the water outlet 3, the magnet 712 is adsorbed on the valve body 1, and water cannot flow out of the water outlet 3. When water needs to be reused, the piston 8 positioned outside the valve body 1 is only required to be pushed upwards to enable the magnet 712 to be separated from the magnetic material, the water flow pushes the first water baffle 71 again, and the water flow flows out of the water outlet 3.
The water tap has the advantages that when water is cut off, the first water baffle can be inverted to the water outlet to seal the water outlet, so that water cannot flow out of the water outlet, water resources are saved, the first water baffle is provided with the magnet and can be adsorbed on the valve body, and water cannot flow out even if the water tap is opened when water comes, so that the purpose of self-closing is achieved, and the water tap is suitable for being used in families. When water needs to be discharged again, the first water baffle is pushed away from the water outlet through the piston.
It should be noted that the above-mentioned preferred embodiments are merely illustrative of the technical concepts and features of the present invention, and are intended to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
