[0001] The present invention relates to the technical field of water pipe valves, and particularly to an automatic water-saving valve for water leakage of water pipes. Background Art

[0002] The transportation of tap water connected to residential households is usually taken out from a waterworks and distributed to the water supply tanks in each place, and then the water supply tanks are connected to each household through water pipes. A valve is provided on the water pipe. After long-term use, the valve is prone to aging and rusting, resulting in serious water leakage after a certain period of use. The water supply tank and the water pipe are usually installed in places where people cannot see them usually. Therefore, the water leakage of the valve is not easy to be discovered. If the water leakage is not discovered until a long time after it occurs, a large amount of water leakage will be generated during this period, which not only causes economic losses, but also causes great waste of water resources.

In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] As Figure 1 and Figure 2 shown, an embodiment of the water pipe leakage - saving automatic valve of the present invention. There is a water pipe valve 200 provided on the existing water pipe 100 for conveying water to control the water conveyance volume. The water pipe valve 200 adopts a non - electric valve, and the opening and closing of the water pipe valve 200 can be realized by manually rotating the non - electric valve rotating handle 201. After long - term use, the water pipe valve 200 will leak due to aging and rusting. The water pipe leakage - saving automatic valve of this embodiment is used to block the water pipe 100 when the leakage volume at the water pipe valve 200 is large to prevent the water pipe 100 from leaking continuously.

[0044] See Figure 1 , the water pipe leakage - saving automatic valve of this embodiment includes an electric valve 1, a driving member 2, a monitoring water tank 3, a floating block 4, and a control member 5.

[0045] Among them, the electric valve 1 is installed on the water pipe 100, and the electric valve 1 is located upstream of the water pipe valve 200, that is, the water in the water pipe 100 first passes through the electric valve 1 and then through the water pipe valve 200. Under normal conditions, the electric valve 1 is in an open state, so that the water pipe 100 remains unobstructed and can transport water normally.

[0046] The driving member 2 is connected to the electric valve 1, and the driving member 2 is used to drive the electric valve 1 to close and block the water pipe 100.

[0047] The monitoring water tank 3 is arranged below the water pipe valve 200, and the monitoring water tank 3 is used to receive the water leakage at the water pipe valve 200.

[0048] The floating block 4 is arranged in the monitoring water tank 3, and the floating block 4 rises and falls with the rise and fall of the water level in the monitoring water tank 3. A contact block 6 is arranged on the floating block 4, and the contact block 6 rises and falls synchronously with the floating block 4.

[0049] The control member 5 is connected to the driving member 2. The control member 5 is provided with a contact head 50, and the contact head 50 is located above the contact block 6. In the initial state, there is a gap between the contact block 6 and the contact head 50, and both the control member 5 and the driving member 2 do not work. When the water leakage amount at the water pipe valve 200 increases and the water level in the monitoring water tank 3 rises, the floating block 4 will rise with the rising water level, and the contact block 6 will approach the contact head 50 as the floating block 4 rises. When the water leakage amount at the water pipe valve 200 reaches the set water leakage amount, the contact block 6 rises to contact the contact head 50, so that the control member 5 is triggered. The triggered control member 5 controls the driving member 2 to start, so that the driving member 2 drives the electric valve 1 to close and block the water pipe 100, so that the water pipe 100 no longer transports water, and thus the water pipe valve 200 no longer leaks water.

[0050] Thus, the water leakage and water-saving automatic valve of this embodiment can monitor the water leakage situation at the water pipe valve 200 through the cooperation of the monitoring water tank 3, the floating block 4 and the control member 5, and when the water leakage amount at the water pipe valve 200 reaches the set water leakage amount, the control member 5 can be automatically triggered by the contact between the contact block 6 on the floating block 4 and the contact head 50 of the control member 5, so that the control member 5 controls the driving member 2 to start and drives the electric valve 1 to close, preventing the water pipe 100 from continuing to transport water, thereby timely preventing the water pipe valve 200 from continuing to leak water and avoiding waste of water resources and economic losses.

[0051] In this embodiment, to make the monitoring of the water leakage amount at the water pipe valve 200 by the monitoring water tank 3 more accurate, preferably, a drain port 30 is provided at the bottom of the monitoring water tank 3, and the water leakage at the water pipe valve 200 received in the monitoring water tank 3 can be discharged from the drain port 30 at the bottom of the monitoring water tank 3. When the water leakage amount at the water pipe valve 200 is small, such that the amount of water injected into the monitoring water tank 3 is less than the drainage amount at the drain port 30 of the monitoring water tank 3, or when the amount of water injected into the monitoring water tank 3 is equal to the drainage amount at the drain port 30 of the monitoring water tank 3, the water level in the monitoring water tank 3 will not rise, and there is a gap between the contact block 6 on the floating block 4 and the contact head 50 of the control member 5, and the control member 5 will not be triggered. At this time, the electric valve 1 remains open, and the water pipe 100 remains unblocked, and normal water conveyance is maintained in the case of a small water leakage amount at the water pipe valve 200. When the water leakage amount at the water pipe valve 200 is large, such that the amount of water injected into the monitoring water tank 3 is greater than the drainage amount at the drain port 30 of the monitoring water tank 3, the water level in the monitoring water tank 3 will rise, causing the floating block 4 to drive the contact block 6 to rise until the contact block 6 contacts the contact head 50 of the control member 5 and triggers the control member 5. At this time, the driving member 2 starts and drives the electric valve 1 to close to block the water pipe 100, so that no more water leaks at the water pipe valve 200. Thus, the water level in the monitoring water tank 3 will no longer rise. Since the drain port 30 keeps draining water, the water level in the monitoring water tank 3 will gradually decrease, causing the floating block 4 to drive the contact block 6 to descend, and the contact block 6 separates from the contact head 50 of the control member 5, causing the control member 5 to disconnect. At this time, the driving member 2 stops driving the electric valve 1, so that the electric valve 1 remains in the closed state of blocking the water pipe 100, waiting for the water pipe valve 200 to be repaired.

[0052] In this embodiment, preferably, a vertical guide rod 7 is provided in the monitoring water tank 3, and the floating block 4 is arranged on the guide rod 7 so as to be able to move up and down along the guide rod 7. The guide rod 7 can play a guiding role in the up and down movement of the floating block 4 in the monitoring water tank 3, which is beneficial to ensuring the accuracy of the monitoring of the water leakage situation at the water pipe valve 200 by the monitoring water tank 3. Preferably, the guide rod 7 is vertically arranged on a side wall of the monitoring water tank 3, the floating block 4 is slidably mounted on the guide rod, and the contact block 6 is fixedly connected to the floating block 4 and is located above the floating block 4.

[0053] In this embodiment, preferably, the driving member 2 can be a motor. The control member 5 controls the rotation shaft of the motor to rotate or stop rotating.

[0054] Preferably, the electric valve 1 has a rotating head 10 which is rotatably inserted through the pipe wall of the water pipe 100, and the rotating head 10 is connected to the rotating shaft of the motor. Under normal conditions, the motor is not started, and there is a gap between the end face of the end of the rotating head 10 extending into the water pipe 100 and the inner peripheral surface of the water pipe 100, so that the electric valve 1 is in an open state and the water pipe 100 remains unobstructed. When the motor is started, the rotation of the rotating shaft of the motor drives the rotating head 10 of the electric valve 1 to rotate accordingly, and drives the rotating head 10 to feed towards the inner peripheral surface of the water pipe 100 until the end face of the end of the rotating head 10 extending into the water pipe 100 abuts against the inner peripheral surface of the water pipe 100, so that the electric valve 1 is in a closed state and the water pipe 100 is blocked. The rotating head 10 is preferably a threaded rotating head.

[0055] Preferably, the control member 5 is an electromagnetic relay. An electromagnetic relay is a switch that uses an electromagnet to control the on-off of a working circuit. Refer to Figure 2 , the structure of the electromagnetic relay includes a contact 50, an electromagnet 51, an armature 52, a spring 53, a moving contact 54, a static contact 55, a power supply 56 and a protection resistor 57. The power supply 56 and the protection resistor 57 are connected to the working circuit of the motor (driving member 2). The contact 50 is the wire contact of the electromagnet 51. The contact block 6 on the floating block 4 is a metal block. When the contact block 6 contacts the contact 50, the coil of the electromagnet 51 generates a magnetic field, thereby generating an attractive force on the armature 52, causing the armature 52 to be attracted to the iron core of the electromagnet 51 against the elastic force of the spring 53, driving the moving contact 54 to contact and engage with the static contact 55, the working circuit is closed, the motor is started, and the rotating shaft of the motor rotates; when the contact block 6 separates from the contact 50, the magnetic field of the coil of the electromagnet 51 disappears, and the armature 52 returns to its original position under the elastic force of the spring 53, causing the moving contact 54 to separate from the static contact 55, the working circuit is disconnected, the motor stops working, and the rotating shaft of the motor stops rotating.

[0056] Preferably, refer to Figure 1 , the automatic water leakage and water saving valve for a water pipe in this embodiment further includes an electrical box 8, and the control member 5 is accommodated in the electrical box 8. Preferably, the electrical box 8 is placed on one side of the monitoring water tank 3 and close to the position of the floating block 6 in the detection water tank 3, so that the contact 50 of the control member 5 is located above the contact block 6 on the floating block 6.

[0057] Preferably, refer to Figure 1 , the water pipe 100 is installed on the water supply tank 300, and a support base 301 is provided on the water supply tank 300, and the driving member 2 is fixedly installed on the support base 301. A base 302 can also be provided at the bottom of the water supply tank 300, and the base 302 is used to support the water supply tank 300.

[0058] The automatic water leakage and water saving valve for a water pipe in this embodiment can be applied to various water pipes, especially water pipes where it is difficult to observe water leakage due to their concealed installation positions, such as the main water pipe of a water tank.

[0059] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
