Description

Technical Field

[0001] This application relates to the field of water conservancy pipeline technology, and in particular to an adjustable sealing and water-stopping socket connection device for water conservancy pipelines. Background Technology

[0002] Water conservancy pipelines are pipeline systems used to transport water or other liquids, and are widely used in water conservancy projects such as water supply, drainage, and irrigation. The design and construction of water conservancy pipelines are crucial aspects of water conservancy projects, involving multiple factors such as pipeline material, size, pressure, and flow velocity. During the installation of water conservancy pipelines, socket connections are required, and the connections must be sealed to prevent leakage.

[0003] Traditional water conservancy pipeline socket connection devices typically connect two sets of pipes together using flanges and tighten them with bolts. Rubber sealing rings are installed at the pipe connection points for sealing and water prevention. However, due to errors during the connection process, the pipe connection distance may be insufficient, resulting in a large length difference in the middle, which affects the construction work of the workers.

[0004] Therefore, an adjustable sealing and water-stopping socket connection device for hydraulic pipelines is proposed. Utility Model Content

[0005] This application provides an adjustable sealing and water-stopping hydraulic pipeline socket connection device to solve the problem that the pipeline connection distance is insufficient and there is a large length difference in the middle due to errors in the pipeline connection process.

[0006] This application provides an adjustable sealing and water-stopping hydraulic pipeline socket connection device, including a connecting flange A, a socket pipe fixedly installed on one side of the connecting flange A, a connecting tube inserted into the socket pipe, a rubber sealing ring sleeved on the surface of the connecting tube, a silicone sealing ring fixedly installed on one side of the rubber sealing ring, a connecting flange B fixedly installed at one end of the connecting tube, a fixing pipe fixedly installed on one side of both the connecting flange A and the connecting flange B, an adjusting pipe fixedly installed at one end of the fixing pipe, a connecting pipe fixedly installed at one end of the adjusting pipe, a polyurethane elastic sleeve fixedly installed at one end of the connecting tube, a buffer spring fixedly installed inside the polyurethane elastic sleeve, and a damper sleeved inside the buffer spring.

[0007] Preferably, a connecting screw hole is provided on one side of the top surface of the connecting pipe, and a connecting stud is passed through the internal thread of the connecting screw hole. The connecting stud is used to connect the adjusting pipe and the fixed pipe.

[0008] Preferably, the top surface of the regulating tube is provided with a plurality of limiting screw holes along the axial direction. The limiting screw holes are adapted to the connecting studs and are used to fix the connecting studs.

[0009] Preferably, both the A connecting flange and the B connecting flange have mounting screw holes on their surfaces, and the internal threads of the mounting screw holes are threaded through by mounting studs, which are used to connect the A connecting flange and the B connecting flange.

[0010] Preferably, a connecting plate is fixedly provided on one side of the polyurethane elastic sleeve, and a pipe connecting screw is fixedly provided on one side of the connecting plate. The pipe connecting screw is used to connect to the water conservancy pipeline.

[0011] Preferably, a rubber ring is fitted onto the surface of the pipe connecting screw, and a silicone ring is provided on one side of the pipe of the rubber ring. The rubber ring and the silicone ring are used to seal the connection between the pipe connecting screw and the water conservancy management.

[0012] Preferably, one end of the mounting stud is threaded with a locking nut, and there are four sets of mounting studs and locking nuts arranged in a circular array. The locking nut is used for pipe mounting studs. Beneficial effects

[0013] Considering that errors may occur during pipe connection, resulting in insufficient pipe connection distance and significant length differences, the adjusting pipe is pulled to slide inside the fixed pipe, and the connecting stud is tightened to fix the adjusting pipe, thus adjusting the overall length. This compensates for pipe installation errors and adapts to different docking distances. Then, the connecting pipe is inserted into the socket pipe, and rubber and silicone sealing rings seal the connection. The silicone sealing ring can fill the tiny gaps under pressure, resulting in a better seal and preventing leakage.

[0029] This utility model provides, for example Figure 1-5 The adjustable sealing and water-stopping hydraulic pipeline socket connection device shown includes an A connecting flange 1, a socket pipe 2 fixedly installed on one side of the A connecting flange 1, a connecting pipe 3 inserted into the socket pipe 2, a rubber sealing ring 10 sleeved on the surface of the connecting pipe 3, a silicone sealing ring 11 fixedly installed on one side of the rubber sealing ring 10, a B connecting flange 12 fixedly installed at one end of the connecting pipe 3, a fixing pipe 13 fixedly installed on one side of both the A connecting flange 1 and the B connecting flange 12, an adjusting pipe 14 fixedly installed at one end of the fixing pipe 13, a connecting pipe 15 fixedly installed at one end of the adjusting pipe 14, a polyurethane elastic sleeve 16 fixedly installed at one end of the connecting pipe 15, a buffer spring 17 fixedly installed inside the polyurethane elastic sleeve 16, and a damper 18 sleeved inside the buffer spring 17.

[0030] In this process, the adjusting pipe 14 is pulled to slide inside the fixed pipe 13, and the connecting stud 4 is turned to fix the adjusting pipe 14, thereby adjusting the overall length. This achieves the effect of compensating for pipe installation errors and adapting to different docking distances. Then, the connecting pipe 3 is inserted into the socket pipe 2. The rubber sealing ring 10 and the silicone sealing ring 11 seal the connection. When the silicone sealing ring 11 is compressed, it can fill the tiny gaps, resulting in a better sealing effect and preventing leakage.

[0031] A connecting screw hole is provided on one side of the top surface of the connecting pipe 15, and the connecting stud 4 is passed through the internal thread of the connecting screw hole.

[0032] The connecting stud 4 is used to connect the adjusting tube 14 and the fixed tube 13.

[0033] The top surface of the regulating tube 14 has several limiting screw holes along the axial direction, which are adapted to the connecting studs 4.

[0034] The limiting screw hole is used to fix the connecting stud 4.

[0035] Both the A connecting flange 1 and the B connecting flange 12 have mounting screw holes on their surfaces, and the internal threads of the mounting screw holes are threaded through the mounting studs 5.

[0036] Among them, the mounting stud 5 is used to connect the A connecting flange 1 and the B connecting flange 12.

[0037] A connecting plate 6 is fixedly installed on one side of the polyurethane elastic sleeve 16, and a pipe connecting screw 7 is fixedly installed on one side of the connecting plate 6.

[0040] Among them, the rubber ring 8 and the silicone ring 9 are used to connect the pipe connecting screw 7 to the external water conservancy pipeline.

[0041] One end of the mounting stud 5 is threaded with a locking nut 19. There are four sets of mounting studs 5 and locking nuts 19, which are arranged in a ring array.

[0042] Among them, the locking nut 19 is used to fix the mounting stud 5.

[0043] Working principle: When using this adjustable sealing and water-stopping hydraulic pipeline socket connection device, pull the adjusting pipe 14 to make it slide inside the fixed pipe 13, and tighten the connecting stud 4 to fix the adjusting pipe 14, adjust the overall length, compensate for pipeline installation errors, adapt to different docking distances, and then insert the connecting pipe 3 into the socket pipe 2. The rubber sealing ring 10 and the silicone sealing ring 11 seal the connection.
