Description

Technical Field

[0001] This utility model relates to the field of pipeline anti-leakage technology, and in particular to an anti-leakage structure for municipal rainwater and sewage pipelines. Background Technology

[0002] Municipal stormwater and sewage pipelines refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. They include main pipes, branch pipes and pipes leading to treatment plants. Municipal stormwater and sewage pipelines typically use galvanized iron pipes, copper pipes, stainless steel pipes, PVC pipes and PP pipes, among which PVC plastic pipes are a modern synthetic material pipe material and are used for the discharge of municipal stormwater and sewage in most cases.

[0003] In existing technologies, the structure at pipe connections is often complex and has a high probability of leakage. Most metal components have a shortened service life due to corrosion from water and air, resulting in significant increased costs during later maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a seepage-proof structure for municipal stormwater and sewage pipes, which solves the problems of poor seepage prevention effect and inconvenient installation of existing sewage pipes at the connection points.

[0005] To achieve the above objectives, a leak-proof structure for municipal stormwater and sewage pipes is provided, comprising: an outer sleeve, two fasteners fixedly connected to the outside of the outer sleeve, the two fasteners being symmetrically arranged on both horizontal sides of the outer sleeve, and an inner sleeve fitted inside the outer sleeve, which facilitates operation by construction personnel during installation;

[0006] A rubber gasket is fixedly connected inside the outer sleeve, and three valves are fixedly connected inside the rubber gasket. A first sealing ring is fitted onto the outside of the outer sleeve, and a third sealing ring is provided to the left of the first sealing ring. The inner surface of the third sealing ring is fixedly connected to the outside of the inner sleeve to improve the sealing performance at the connection.

[0007] According to the aforementioned municipal stormwater and sewage pipeline anti-leakage structure, the end of the outer sleeve away from the locking tenon is fixedly connected to the first pipe, and two first gaskets are provided between the outer surface of the first pipe and the inner side of the outer sleeve to prevent leakage at the connection between the outer sleeve and the first pipe.

[0008] According to the aforementioned municipal stormwater and sewage pipeline anti-leakage structure, a second pipeline is fixedly connected inside the inner sleeve, and two second gaskets are provided between the outer surface of the second pipeline and the inner side of the inner sleeve to prevent leakage at the connection between the inner sleeve and the second pipeline.

[0009] According to the aforementioned municipal stormwater and sewage pipeline anti-leakage structure, the inner sleeve has a groove on its side that is fixedly connected to a second sealing ring. The second sealing ring is made of corrosion-resistant material to prevent leakage at the interface between the first and second pipelines.

[0010] According to the aforementioned municipal stormwater and sewage pipeline anti-leakage structure, the tenon is made of hard plastic, and the front end of the tenon is inclined to facilitate the inner sleeve being inserted into the outer sleeve, thereby improving the stability after installation.

[0011] According to the aforementioned municipal stormwater and sewage pipeline anti-seepage structure, the outer sleeve is made of rigid polyvinyl chloride (PVC), and the inner sleeve is also made of rigid PVC, thereby improving the service life of the connectors.

[0012] According to the aforementioned municipal stormwater and sewage pipeline anti-leakage structure, the valve is made of elastic corrosion-resistant rubber, and the valve is staggered from the first sealing ring and the third sealing ring. Multiple sealing layers reduce the possibility of leakage and extend the maintenance cycle.

[0013] According to the aforementioned municipal stormwater and sewage pipeline anti-leakage structure, the three valve sides are tightly attached to the outside of the inner sleeve, and the outside of the first sealing ring and the third sealing ring are tightly attached to the inside of the outer sleeve, so that multiple sealing layers can provide high sealing performance.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. This utility model facilitates pipe installation by using the locking tabs on the outside of the outer sleeve, and also makes disassembly easy during subsequent maintenance. The overall non-metallic structure reduces corrosion problems and extends the maintenance cycle.

[0016] 2. This utility model forms a multi-layer sealing structure through the sealing ring outside the inner sleeve and the valve inside the outer sleeve. The sealing components can be disassembled, reducing the risk of leakage and extending the subsequent maintenance time, thereby reducing cost investment in the overall sewage pipeline project.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] Reference Figure 1-4 This utility model embodiment provides a leak-proof structure for municipal rainwater and sewage pipes, which includes: an outer sleeve 2, two tenons 5 fixedly connected to the outside of the outer sleeve 2, the two tenons 5 being symmetrically arranged on both horizontal sides of the outer sleeve 2, an inner sleeve 4 being sleeved inside the outer sleeve 2, the inner sleeve 4 being pushed into the outer sleeve 2 after being coated with lubricant, the two tenons 5 being pushed outward, and the tenons 5 springing back after the inner sleeve 4 is fully inserted.

[0027] The outer sleeve 2 is fixedly connected to a rubber pad 8, and three valves 10 are fixedly connected inside the rubber pad 8. The outer sleeve 2 is fitted with a first sealing ring 6, and a third sealing ring 11 is provided to the left of the first sealing ring 6. The inner surface of the third sealing ring 11 is fixedly connected to the outer surface of the inner sleeve 4. When the inner sleeve 4 is pushed into the outer sleeve 2, the valves 10 tilt in the direction of movement of the inner sleeve 4 and stick tightly to the inner sleeve 4.

[0028] The end of the outer sleeve 2 away from the latch 5 is fixedly connected to the first pipe 1. Two first washers 9 are provided between the outer surface of the first pipe 1 and the inner side of the outer sleeve 2 to prevent leakage at the connection between the outer sleeve 2 and the first pipe 1.
