Description

Technical Field

[0001] The invention belongs to the technical field of pipeline valves, and in particular relates to an anti-leakage active water stop valve. Background Art

[0002] Pipeline systems are widely used in daily life and industrial production. However, pipeline leakage occurs frequently. Traditional water stop valves often rely on water pressure difference or manual operation to close the valve after leakage occurs, and cannot actively and timely stop leakage, which may lead to waste of water resources, property loss and even safety accidents. For example, in household water pipes, once the faucet, water pipe joints and other parts are broken or poorly sealed, traditional water stop valves are difficult to respond in the first time, causing a large amount of water resources to flow in vain, soaking the floor, furniture, etc., causing unnecessary economic losses and life troubles to the family. In industrial pipeline systems, if corrosive liquids or high-temperature and high-pressure liquids are transported, if the leakage is not stopped in time, it may corrode equipment, damage the production environment, and even cause explosions and other serious consequences. Summary of the invention

[0003] The present invention aims to provide an anti-leakage active water stop valve, which can actively detect water leakage and quickly and automatically close the valve to effectively prevent the leakage from further expanding.

[0004] In order to solve the above technical problems, the specific technical solutions of the present invention are as follows:

[0005] In some embodiments of the present application, a water-leakage-proof active water-stop valve is provided, comprising:

[0006] A first body, wherein a first flow cavity is provided inside the first body and a first connection end is provided on the top of the first body;

[0007] An external thread is provided on the outer wall of the first connecting end;

[0008] A first receiving groove, wherein the first receiving groove is disposed at the bottom of the first flow cavity;

[0009] A second body, wherein a second flow cavity is provided inside the second body and a clamping groove is provided on the top of the second body, wherein a through hole is provided on one side of the second body;

[0010] A third body, the third body is arranged at the bottom of the second body, and is fixedly connected to the second body. A third flow cavity is arranged inside the third body, and a limiting protrusion is arranged in the third flow cavity. A second connection end is arranged below the limiting protrusion;

[0011] The second connecting end is provided with an internal thread;

[0012] The second connection end is threadedly connected to the first connection end.

[0013] In some embodiments of the present application, the diameter of the third flow cavity above the limiting protrusion is smaller than the diameter of the third flow cavity below the limiting protrusion.

[0014] Compared with the prior art, the beneficial effect of the present invention lies in that, by connecting the first body with the third body, and opening a through hole on the second body, the connecting pipe is matched with the stop valve and a stainless steel ball is arranged in the connecting pipe. Under normal circumstances, water flows through the first flow cavity, the second flow cavity and the third flow cavity. When a burst or water leakage occurs, the water flow speed is accelerated and the water pressure increases, so that the stainless steel ball opens, and the water flows into the stop valve through the connecting pipe, thereby causing the stop valve to close the pipeline. The mechanical stopping method is adopted, which is not only low in cost, but also has a better and more stable stopping effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] See attached Figure 1-2 As shown, according to some embodiments of the present application, it includes:

[0021] A first main body 1, wherein a first circulation cavity 101 is provided inside the first main body 1 (the inner diameter of the first circulation cavity 101 is 27 mm), and a first connecting end 102 is provided at the top of the first main body 1 (the inner diameter of the first connecting end 102 is 15 mm, and the outer diameter is 21 mm); an external thread is provided on the outer wall of the first connecting end 102;

[0022] A first receiving groove 103, which is disposed at the bottom of the first flow cavity 101, and has an inner diameter of 29 mm and a height of 12 mm;

[0023] A second main body 2, wherein a second flow cavity 201 is provided inside the second main body 2 (the inner diameter of the second flow cavity 201 is 18 mm and the outer diameter is 22 mm), and a clamping groove 202 is provided on the top of the second main body 2 (the inner diameter of the clamping groove 202 is 20 mm and the height is 1.2 mm), wherein a through hole 203 is provided on one side of the second main body 2, the diameter of the through hole 203 is 6 mm, the through hole 203 is connected to the stop valve through a connecting pipe, a stainless steel ball is provided in the through hole 203, and a stainless steel spring is provided on the second through cavity 201 to connect with the stainless steel ball;

[0024] The third body 3 is arranged at the bottom of the second body 2, and is fixedly connected to the second body 2 (it can be an integrated structure), and a third circulation cavity 301 is arranged inside the third circulation cavity 301, and a limiting protrusion 302 is arranged inside the third circulation cavity 301, and a second connecting end 303 is arranged below the limiting protrusion 302; the second connecting end 303 is provided with an internal thread; the second connecting end 303 is threadedly connected to the first connecting end 102.

[0025] The diameter of the third flow cavity 301 above the limiting protrusion 302 is smaller than the diameter of the third flow cavity 301 below the limiting protrusion 302, the upper diameter is 16 mm, and the lower diameter is 21 mm.

[0026] When a burst or water leak occurs, the water flow speed increases and the water pressure increases. The water pressure forces the stainless steel spring to be stressed and the stainless steel ball moves to the side hole. While blocking the water flow from the side hole from changing its center, it increases the pressure of the spring and causes the spring to shrink rapidly. The stainless steel ball arrives at the third flow cavity as the spring shrinks, blocking the water flow and stopping the flow.
