Description

Technical Field

[0001] This utility model relates to the field of water pipeline technology, specifically a fracture-stopping joint. Background Technology

[0002] During the installation and use of building water supply and drainage systems, household water pipes and various fluid transport pipelines, the connection between water pipes and faucets is a critical node in the pipeline system. Its connection stability and sealing reliability directly affect the normal operation of the entire pipeline.

[0003] Currently, most common water pipe fittings on the market use traditional threaded connections, compression fittings, or welding, which mainly serve as simple pipe connections and can only meet the fluid transport needs under normal operating conditions. They lack emergency protection designs for sudden failures. In actual use, due to factors such as pipe aging, improper installation, external impact, and excessive water pressure fluctuations, the connection between the water pipe and the fitting is prone to bursting or breaking. Once such a failure occurs, traditional fittings cannot automatically stop the water flow, and the water in the pipe will continue to leak in large quantities. This will not only cause serious waste of water resources, but may also lead to a series of secondary disasters such as indoor water accumulation, damp walls, electrical short circuits, and furniture damage, causing huge property losses to users.

[0004] Therefore, it is necessary to propose a fracture-stopping joint. Utility Model Content

[0005] The purpose of this utility model is to provide a fracture-stopping joint to solve the problem of water pipe joint bursting and failing to achieve automatic water stopping as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fracture-stopping joint includes a connecting module connected to one end of a water pipe, a water-stopping module inserted inside the connecting module, a limit ring fixedly installed inside one end of the water pipe, and one end of the water-stopping module abutting against one side of the limit ring; the connecting module includes a transfer joint and a guide tube, one end of the guide tube being fixedly installed on the transfer joint, the transfer joint being threadedly connected to the water pipe, and the water-stopping module being inserted into the transfer joint and the guide tube.

[0008] Preferably, the guide tube has a first opening evenly installed on its side wall, and one end of the transfer joint has a first threaded groove.

[0009] Preferably, the inner wall of the other end of the transfer connector is provided with a second threaded groove, and a retaining groove is provided in the second threaded groove.

[0010] Preferably, the water-stopping module includes a connecting pipe and a retaining ring, the retaining ring being fixedly installed at one end of the connecting pipe, the connecting pipe being inserted into the guide pipe, and the retaining ring abutting against the limiting ring.

[0011] Preferably, a connector is installed at the other end of the connecting pipe and passes through the intermediate connector, and a second opening is evenly provided on the side wall of the connecting pipe.

[0012] Preferably, a sealing gasket is fitted on the end of the connecting pipe away from the abutment ring, and a thickened sealing ring is clamped on the connecting head.

[0013] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0014] By setting up intermediate joints and guide tubes in the connection module, a stable assembly frame is provided for the overall structure, ensuring smooth installation and improving the sealing performance of the connection.

[0015] The second opening of the connecting pipe ensures normal water supply. By setting a water-stop module, when the pipe bursts, the sealing gasket and the thickened sealing ring are tightly pressed against the groove under the water flow pressure, which can realize the normal water supply function and automatically block water leakage after the pipe bursts.

[0025] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-4 As shown; a fracture-stopping joint includes a connecting module 1 connected to one end of a water pipe, and a faucet connected to the other end of the water pipe. A water-stopping module 2 is inserted into the inside of the connecting module 1. The function of the connecting module 1 is to connect the water pipe and the water-stopping module 2, to provide installation support and guidance for the water-stopping module 2, and to build the basic assembly frame of the overall joint. A limit ring 3 is fixedly installed inside one end of the water pipe. One end of the water-stopping module 2 abuts against one side of the limit ring 3. The function of the limit ring 3 is to limit and support the water-stopping module 2, to define its installation reference position, and to ensure the stability of the structure.

[0027] like Figures 1-3 As shown, the connecting module 1 includes a transfer joint 101 and a guide tube 102. The transfer joint 101 is threadedly connected to the water pipe. The function of the transfer joint 101 is to achieve a stable connection with the water pipe and provide an installation base for the guide tube. The threaded groove and the slot assist in the assembly of other components, improving the overall reliability of the connection. Teflon tape is wrapped around the connection. One end of the guide tube 102 is fixedly installed on the transfer joint 101, and the other end of the guide tube 102 is inserted into the water pipe. The function of the guide tube 102 is to guide the installation direction of the water-stop module 2. The first opening on its side wall can adapt to the deformation of the connecting pipe, ensuring smooth assembly, and at the same time providing protection for the connecting pipe. The water-stop module 2 is inserted into the transfer joint 101 and the guide tube 102. The side wall of the guide tube 102 is evenly equipped with first openings 103. The function of the first openings 103 is to... To provide deformation space for the connecting pipe 201 when it is inserted into the guide pipe 102, avoid assembly interference between the two, and ensure a smooth installation process, one end of the adapter 101 is provided with a first threaded groove 104. The function of the first threaded groove 104 is to provide an adaptation structure for the threaded connection between the adapter 101 and the water pipe, enhance the sealing and stability of the connection, and wrap the connection with PTFE tape to prevent the connection from loosening. The other end of the adapter 101 is provided with a second threaded groove 105 on its inner wall. The function of the second threaded groove 105 is to cooperate with related components to achieve further assembly and fixation, provide thread adaptation for subsequent component connections, and improve the assembly accuracy of the overall structure. A retaining groove 106 is provided in the second threaded groove 105. The function of the retaining groove 106 is to limit and tighten the sealing gasket 204 and the thickened sealing ring 205 when there is a leak.

[0028] like Figure 4As shown, the water-stopping module 2 includes a connecting pipe 201 and a retaining ring 202. The water-stopping module 2 is used to block water leakage from the faucet pipe after a burst, through its own structure and cooperation with a sealing element, thus achieving the function of stopping water flow after a break. The retaining ring 202 is fixedly installed at one end of the connecting pipe 201. The retaining ring 202 restricts the installation position of the water-stopping module 2 within the connecting module 1. The connecting pipe 201 is inserted into the guide pipe 102, and the retaining ring 202 abuts against the limiting ring 3. The connecting pipe 201 serves as the main support structure of the water-stopping module 2. A connector 206 is installed at the other end of the connecting pipe 201 and passes through the transfer... The connector 101 and the connecting pipe 201 have evenly spaced second openings 203 on their side walls. The second openings 203 allow water to enter the connecting pipe 201 and then flow out through the abutment ring 202. A sealing gasket 204 is fitted on the end of the connecting pipe 201 away from the abutment ring 202. A thickened sealing ring 205 is clamped on the connector 206. When the water pipe at the abutment ring 202 and the limiting ring 3 bursts, the limiting ring 3 can no longer stop the abutment ring 202. At this time, the water flow impacts the connector 206, and the sealing gasket 204 and the thickened sealing ring 205 will be tightly pressed against the groove 106 by the water pressure, thus preventing water leakage.

[0029] The working principle of this utility model is as follows: The intermediate connector 101 of the connecting module 1 is threadedly connected to the water pipe through the first threaded groove 104. Teflon tape is wrapped around the connection point. One end of the guide tube 102 is fixed to the intermediate connector 101, and the other end is inserted into the water pipe. The connecting tube 201 of the water-stop module 2 is inserted into the guide tube 102. The abutment ring 202 of the water-stop module 2 abuts against the limiting ring 3 inside the water pipe, thus defining the installation reference position of the water-stop module 2. An overall connector assembly frame is constructed. The connector 206 of the water-stop module 2 passes through the intermediate connector 101, and the sealing gasket 204 is fitted onto the connecting tube 201 away from the abutment ring 2. At one end of 02, the thickened sealing ring 205 is snapped onto the connector 206. The second threaded groove 105 on the inner wall of the intermediate connector 101 provides thread adaptation for subsequent assembly, and the slot 106 reserves space for the sealing component to limit the position. The water in the water pipe enters the interior of the connecting pipe 201 through the second opening 203 on the side wall of the connecting pipe 201, and flows out to the faucet through the abutment ring 202 to achieve normal water supply. The first opening 103 on the side wall of the guide pipe 102 provides deformation space when the connecting pipe 201 is inserted, avoiding assembly interference between the connecting pipe 201 and the guide pipe 102, ensuring smooth assembly and structural protection.

[0030] The PTFE tape at the connection between the intermediate connector 101 and the water pipe, in conjunction with the first threaded groove 104, enhances the sealing and stability of the connection, preventing loosening. When the water pipe at the abutment ring 202 and the limiting ring 3 bursts, the limiting ring 3 loses its abutment and limiting function against the abutment ring 202, and the water-stop module 2 loses its original installation positioning reference. Due to the pressure impact of the water flow in the water pipe on the connector 206, under the action of water flow pressure, the sealing gasket 204 and the thickened sealing ring 205 are pushed towards the slot 106 of the intermediate connector 101. The sealing gasket 204 and the thickened sealing ring 205 are tightly attached to the inner wall of the slot 106, and the limiting and clamping effect of the slot 106 forms a sealing surface, blocking the leakage channel of the water flow in the water pipe and realizing the water-stopping function after the breakage.

[0031] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
