Description

TECHNICAL FIELD

[0001] The utility model relates to the field of water pipe leak stoppage, in particular to a water pipe emergency leak stoppage device. BACKGROUND

[0002] In the modern society's water pipe system, the pipeline as the key infrastructure of conveying water resources, its stable operation is directly related to people's daily life and the normal production of industrial production. However, the water pipe often appears the water leakage phenomenon because of the aging, corrosion, external damage or construction quality problem and other factors. This not only will cause the waste of water resources, increases the economic cost, but also can threaten the surrounding environment and the building structure safety. Especially in the emergency, such as the water pipe burst causes the large water flow to spout, the fast and effective emergency leak stoppage becomes the urgent matter.

[0003] In the process of clamping the leak stoppage device, because the water pressure in the water pipe always exists and can fluctuate because of the water leakage, the continuous pressure effect will generate the outward pushing force to the leak stoppage device, makes the clamping force between the device and the pipeline gradually weakens, further leads to the leak stoppage device to appear the loosening easily, cannot be stably fixed at the leakage point, influences the leak stoppage effect, brings the great challenge to the emergency treatment.

[0004] Therefore we make improvement to this, propose a water pipe emergency leak stoppage device. UTILITY MODEL CONTENT

[0005] In order to realize the above utility model purpose, the utility model provides a water pipe emergency leak stoppage device to improve the above problem.

[0006] The application is as follows:

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 An emergency leak-sealing device for water pipes includes an upper cover 1 and a lower cover 2 symmetrically arranged on both sides of the leak in the water pipe. The upper cover 1 and the lower cover 2 gradually increase in diameter from both ends toward the middle.

[0031] The connecting plate 12 is fixedly connected to the periphery of the upper cover 1 and the lower cover 2, and has a through groove on the top for bolts to pass through.

[0032] The threaded channel 3 is opened on the upper cover 1, and the threaded channel 3 tends to sink down to the inner wall of the upper cover 1 from the center of the thread to the end of the thread.

[0033] The water inlet end 31 is located at the center port of the threaded channel 3 on the upper cover 1 and extends to the inner wall of the upper cover 1;

[0034] The water outlet 32 ​​is located at the end of the threaded channel 3 on the upper cover 1 and extends to the inner wall of the upper cover 1, and the water outlet 32 ​​and the water inlet 31 are on the same straight line.

[0035] The guide block 33 is fixedly connected to the inner wall of the upper cover 1 and guides the water outlet 32 ​​to the side near the water inlet 31.

[0036] When the water jet from the water pipe flows through the inlet end 31, passes through the threaded channel 3, and flows back to the water pipe through the outlet end 32, the water flow forms pressure in the threaded channel 3 in the direction of the thread tangent, which reduces the tendency of the upper cover 1 and the lower cover 2 to separate.

[0037] When a leak occurs on one or more sides of the water pipe, the upper cover 1 and the lower cover 2 are installed on the periphery of the pipe. At this time, the upper cover 1 is aligned with the leak location by the marking block 4, and is fixed to the periphery of the water pipe with the connecting plate 12 under the connection of bolts or other connecting parts.

[0038] At this time, the water flow converges in the cavity formed by the upper cover 1 and the lower cover 2, and the water flow generates a lateral pressure on the circular truncated cone part of the upper cover 1 and the lower cover 2, so that the sealing ring 5 at the end of the upper and lower covers generates a pressure to the pipeline, and the water flow is more difficult to escape from the position of the sealing ring 5;

[0039] Meanwhile, the flow guide block 33 extends into the position close to the leakage side, and because the water flow is difficult to pass through the flow guide groove in the flow guide block 33, the water flow preferentially enters the water inlet end 31 and gradually flows through the threaded channel 3. Because the water flow is redirected and generates a pressure to the side wall of the threaded channel 3, the upper cover 1 is prevented from being directly impacted, and uniform circumferential pressure is obtained to finally keep stable.

[0040] And because the threaded channel 3 has a sinking trend, the impact force of the direct water flow is converted into a stable water flow as much as possible, and the water flow is limited from flowing back to the threaded channel 3 from the water outlet end 32. When the water flow finally reaches the water outlet end 32 and is guided to the water inlet end 31 position by the flow guide block 33, because the water inlet end 31 continuously supplies water, a certain negative pressure is generated, and the water outlet end 32 compensates for the negative pressure to flow out of the water outlet end 32 and flow back to the water pipe.

[0041] The water flow diameter of the threaded channel 3 gradually decreases from the water inlet end 31 to the water outlet end 32. The gradually reduced water flow channel can ensure that the tangent pressure generated by the water flow in each section always remains stable. Because the pressure of the water inlet end 31 is certainly the largest, the gradually shortened water flow channel can complete the tangent pressure generated by the water flow to the threaded channel 3 through the flow rate of the water.

[0042] The flow guide block 33 forms a plane that guides the water flow to the water inlet end 31 on the water inlet facing surface.

[0043] Further comprising:

[0044] The marker block 4 is fixedly connected to the outer wall of the upper cover 1 and coincides with the vertical surface of the threaded channel 3.

[0045] Further comprising:

[0046] The sealing ring 5 is fixedly connected to the contact surface of the upper cover 1 and the lower cover 2 and the pipeline.

[0047] The technical scope of the utility model is not limited to the content in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
