[0002] In the production processes of many industrial sectors, a large amount of waste heat is generated, which needs to be transferred to the natural environment in a timely manner using heat transfer media to ensure the normal operation of the production process. Natural water is used as a heat transfer medium for industrial waste heat because it has excellent heat transfer performance, low cost, and abundant resources. In industrial production, it is called cooling water. Industrial cooling water is the largest user of industrial water in various countries. Apart from raising the temperature, the physical and chemical properties of cooling water do not change significantly. If appropriate cooling measures are taken to form a recycling system, it is an important way to save industrial water. When connecting cooling water pipelines, joint assemblies are required for assembly.

[0003] However, some existing water pipe joints are often connected by flanges, which have poor sealing performance and are inconvenient to replace. With long-term use, the sealing components are prone to corrosion, leading to liquid leakage and affecting the use of the joint. Utility Model Content

When a leak occurs at the connection between the first water pipe and the second water pipe, the leaked water enters the joint. The joint can store the leaked water. Through the sealing of the second sealing sleeve, the water in the joint will not flow out from the gap of the socket.

By tightening the pressure block, the pressure block can squeeze the second sealing sleeve, causing the second sealing sleeve to deform. As a result, the second sealing sleeve can fit more closely to the gap between the first water pipe, the second water pipe and the insertion port opened on the outer wall of the connector, thereby increasing the sealing performance of the second sealing sleeve.

A pressure block 54 is provided at the lower end of the screw 53. Multiple sets of mounting rods 6 are symmetrically provided on both sides of the outer wall of the connector 1. A second fixing block 7 that cooperates with the mounting rod 6 is provided on the outer wall of the first water pipe 2 and the second water pipe 3. A bolt 8 is threaded into the middle end of the second fixing block 7. A nut 9 is threaded onto the outer wall of the bolt 8.

[0024] The first sealing sleeve 4 is movably inserted into the inner wall of the front end of the first water pipe 2. The outer wall of the first sealing sleeve 4 is in contact with the inner wall of the front end of the first water pipe 2. The inner wall of the first water pipe 2 is fixedly provided with a limiting sleeve 11. The first sealing sleeve 4 and the limiting sleeve 11 are in contact. The two ends of the connector 1 are provided with inlets that cooperate with the first water pipe 2 and the second water pipe 3. The front ends of the first water pipe 2 and the second water pipe 3 are movably inserted through the inlets and inserted into the connector 1. The outer walls of the first water pipe 2 and the second water pipe 3 are in contact with the inlets.

[0025] The first sealing sleeve 4 is movably fitted on the outer wall of the front end of the second water pipe 3, and the front end of the second water pipe 3 is movably inserted into the inner wall of the first water pipe 2.

[0026] The inner wall of the connector 1 is fixedly provided with a third sealing sleeve 12 on both sides. The third sealing sleeve 12 is movably sleeved on the outer wall of the second water pipe 3 and the first water pipe 2. The inner wall of the third sealing sleeve 12 is in contact with the outer wall of the first water pipe 2 and the second water pipe 3.

[0027] The second sealing sleeve 51 is movably fitted on the outer wall of the first water pipe 2 and the second water pipe 3. The outer wall of the second sealing sleeve 51 has a groove that matches the pressure block 54. The pressure block 54 is movably inserted into the groove. The second sealing sleeve 51 fits against the outer wall of the insertion port on both sides of the connector 1.

[0028] The end of the mounting rod 6 away from the second fixing block 7 is hinged to the outer wall of the connector 1. The end of the mounting rod 6 away from the outer wall of the connector 1 is movably inserted into the middle of the second fixing block 7. The middle of the second fixing block 7 has a through hole that matches the bolt 8. The front end of the bolt 8 moves through the through hole.

[0029] The lower end of connector 1 is connected to a liquid outlet valve 10.

[0030] When connecting the first water pipe 2 and the second water pipe 3, firstly, place the second sealing sleeve 51 on both sides of the insertion port on the outer wall of the connector 1. Insert the first sealing sleeve 4 into the inner wall of the front end of the first water pipe 2 until the first sealing sleeve 4 contacts the limiting sleeve 11. Install the first sealing sleeve 4 into the inner wall of the front end. Then, pass the front ends of the first water pipe 2 and the second water pipe 3 through the middle of the second sealing sleeve 51 along both ends of the connector 1 and insert them along the insertion port on the outer wall of the connector 1. Insert the front end of the second water pipe 3 into the inner wall of the front end of the first water pipe 2 until the first water pipe 2 and the second water pipe 3 are fitted together. This completes the connection of the first water pipe 2 and the second water pipe 3. The first sealing sleeve 4 increases the connection between the first water pipe 2 and the second water pipe 3. The sealing at the joint of the two water pipes 3 provides the first layer of protection for the connection between the first water pipe 2 and the second water pipe 3. The second sealing sleeve 51 can increase the sealing between the connector 1 and the first water pipe 2 and the second water pipe 3, providing the second layer of protection for the connection between the first water pipe 2 and the second water pipe 3. Then, rotate the first water pipe 2 and the second water pipe 3 so that the mounting rod 6 and the second fixing block 7 correspond one-to-one. Rotate the second fixing block 7 and insert the front end of the second fixing block 7 into the mounting rod 6. Then, pass the bolt 8 through the through holes opened in the middle of the mounting rod 6 and the second fixing block 7 in sequence. Then, rotate the nut 9 and thread the nut 9 onto the outer wall of the front end of the bolt 8 so that the nut 9 and the outer wall of the second fixing block 7 fit together. This completes the fixation of the first water pipe 2 and the second water pipe 3, ensuring a stable connection between the two ends of the connector 1. Next, the second sealing sleeve 51 is rotated along the outer wall of the first water pipe 2 and the second water pipe 3, aligning the slot on the outer wall of the second sealing sleeve 51 with the pressure block 54. The screw 53 is then rotated along the first fixing block 52 to insert the pressure block 54 into the slot, thus fixing the second sealing sleeve 51. Tightening the pressure block 54 compresses the second sealing sleeve 51, causing it to deform. This allows the second sealing sleeve 51 to better fit the gap between the first water pipe 2, the second water pipe 3, and the insertion opening on the outer wall of the connector 1, increasing the sealing sleeve's strength. The sealing performance of the second sealing sleeve 51 is such that when a leak occurs at the junction of the first water pipe 2 and the second water pipe 3, the leaked water enters the connector 1. The connector 1 can store the leaked water. Through the sealing of the second sealing sleeve 51, the water in the connector 1 will not flow out from the gap of the socket, thus avoiding the problem of water waste caused by leakage at the junction of the first water pipe 2 and the second water pipe 3. Moreover, opening the outlet valve 10 can drain the water stored in the connector 1. Both the second sealing sleeve 51 and the first sealing sleeve 4 can be disassembled, which facilitates the replacement of the second sealing sleeve 51 and the first sealing sleeve 4, and avoids the problem of corrosion of the second sealing sleeve 51 and the first sealing sleeve 4 after long-term use, which would cause a decrease in sealing performance.
