Detailed Description

The invention is further described below with reference to the accompanying drawings:

the quick automatic sealing pipeline joint is composed of a joint body 1, a fixing ring 2, a sealing ring 3, a compression ring 4, a bolt 5, an anti-drop chain 6 and a self-locking hook 7 (see attached figures 1-2), wherein the joint body 1 can be made into a straight cylindrical structure, an arc cylindrical structure or a conical cylindrical structure according to the actual needs of engineering. A fixing ring 2 is fixedly arranged on the inner wall of one end or two ends of the joint body 1, at least three screw holes are uniformly distributed on the fixing ring 2, a bolt 5 is connected with the screw holes on the fixing ring 2, a sealing ring 3 and a compression ring 4 are arranged on the outer surface of the fixing ring 2 from inside to outside through the bolt 5, the sealing ring 3 and the compression ring 4 are compressed on the outer surface of the fixing ring 2 through the bolt 5, and the diameter of the inner ring of the sealing ring 3 is 5-10 mm smaller than the outer diameter of a connecting pipeline 8; the anti-dropping chain joint is characterized in that the anti-dropping chain 6 is fixedly arranged in the middle of the outer surface of the joint body 1, the self-locking hook 7 is arranged at the other end of the anti-dropping chain 6, the anti-dropping chain 6 is connected with the connecting ring on the connecting pipeline 8 through the self-locking hook 7 to prevent the connecting pipeline 8 from dropping out of the joint body 1, and the number of the anti-dropping chains 6 is equal to that of the connecting pipelines 8. When connecting tube 8 is fixed through the anchor block or other fixed facilities on the fixed basis in the design, connecting tube 8 can not produce the displacement in the use, just can need not install anticreep chain 6 on the joint body 1.

When the quick automatic sealing pipeline joint is connected and installed with a connecting pipeline 8, after the connecting pipeline 8 is inserted into a sealing ring 3 of a joint body 1, the central lines of the connecting pipeline 8 and the joint body 1 can be coaxial (see figure 3) or form a certain angle (see figure 4); after the connecting pipeline 8 is inserted into the sealing ring 3 of the joint body 1, the contact part of the sealing ring 3 and the outer wall of the connecting pipeline 8 is turned and rolled towards the inside of the joint body 1 and is tightly sleeved on the surface of the outer wall of the connecting pipeline 8.

This quick self-sealing's pipe joint's installation use does, according to the engineering design requirement, with solid fixed ring 2 welding on the inner wall at the one end of connecting body 1 or both ends, put sealing washer 3 on solid fixed ring 2, put clamp ring 4 again, then through bolt 5 with gu screw on fixed ring 2 with sealing washer 3 and clamp ring 4 set up on solid fixed ring 2 can, again according to the engineering design requirement with one or two connecting tube 8 insert connect body 1's one end or both ends in sealing washer 3, again with on the anticreep chain 6 on the auto-lock couple 7 collude on the go-between on connecting tube 8 can. After the connecting pipeline 8 is inserted, the contact part of the sealing ring 3 and the outer wall of the connecting pipeline 8 can be turned and rolled towards the inside of the joint body 1, so that the sealing ring 3 is tightly sleeved on the surface of the outer wall of the connecting pipeline 8 and is sealed. When the connecting pipeline 8 and the pipeline joint work, the liquid in the pipeline of the joint body 1 can apply pressure to the turned-over part of the sealing ring 3, so that the sealing ring 3 can be sleeved on the outer wall of the connecting pipeline 8 more tightly without any leakage, and the liquid pressure in the pipeline is higher, so that the sealing ring 3 is more sealed on the connecting pipeline 8.

When the quick automatic sealing pipeline joint is installed, a pipeline is only required to be inserted into the sealing ring hole, the quick automatic sealing pipeline joint is convenient and quick to install and disassemble, has a good sealing effect, can be universally adjusted in the direction of the pipeline during field installation, can be used as an elbow, and can be used for connecting pipelines with various diameters only by adjusting the diameter of the pipeline joint, so that standardization and selective use can be realized; the utility model discloses can adapt to various pipe connection, the specially adapted is used at the anti-disaster scene of robbing the row to rush to irritate and the scene of rescuing to fight, can practice thrift a large amount of valuable time for the rescue scene, and social and economic benefits are showing.
