Description

Technical Field

[0001] The utility model relates to the technical field of connecting pressure pipelines, in particular to a pressure pipeline for connection. Background Art

[0002] Pressure piping refers to all pipelines that are subject to internal or external pressure, regardless of the medium inside the pipe. Pressure piping is a part of a pipeline that is used to transport, distribute, mix, separate, discharge, meter, control and stop the flow of fluids. It is an assembly consisting of pipes, pipe fittings, flanges, bolted connections, gaskets, valves, other components or pressure-bearing parts and supports. Pressure piping is widely used and is applicable to all walks of life.

[0003] For example, a pressure pipe connection and sealing device for conveying fluids with an authorization announcement number of CN214500355U and an announcement date of 2021.10.26 uses pipe sleeves, docking keys, linings, pressure-responsive seals, guide bushings, keys, ferrules, ferrule limit devices and other components to radially connect two seamless pipes with grooves processed at the butt heads, and seal the pipes to prevent fluid leakage. This structure is resistant to high pressure and can be used for pipe connections of various diameters. It is easy to install and connect, and easy to replace seals. Especially for some rigidly connected long-distance liquid supply pipes, it has the advantages of safe and reliable sealing that is not easily damaged, convenient production and processing, and processing the connection grooves without damaging the pipe's compressive strength or reducing the inner diameter of the pipe.

[0004] The existing pressure pipes used for connection are not firmly fixed at the connection when the pressure pipe is connected for too long, and the pressure pipe is easy to fall off from the connection of the generator pipe. The hot steam ejected by the falling pressure pipe may cause scalding to the workers. Therefore, it is urgent to design a pressure pipe for connection to solve the above problems.

When the generator conduit 2 needs to be fixed, the connecting pipe 5 drives the inserting rod 23, the inserting rod 23 is inserted into the socket 4, the inserting rod 23 is rotated, and the inserting rod 23 is inserted in the socket 4, the plug rod 23 is clamped in the socket 4, the circular groove 9 on the plug rod 23 is aligned with the limiting round head 8, and the limiting round head 8 is clamped in the circular groove 9. Since the limiting spring 22 provides elastic force, the limiting spring 22 squeezes the limiting rod 7, and the limiting rod 7 moves in the limiting groove 6. The limiting rod 7 drives the limiting round head 8 to move, and the limiting spring 22 tightly clamps the limiting round head 8 in the circular groove 9, so that the two generator conduits 2 can be stably fixed at the connection, avoiding the generator conduit 2 in the pressure pipe from loosening at the connection after long-term use, causing hot steam to erupt. The two pressure pipe bodies 1 are sleeved on the outer walls of the insert pipe 3 and the connecting pipe 5, and the fixing bolts 16 are passed through the fixing lugs 14. The nuts 17 are threadedly sleeved on the outer walls of the fixing bolts 16. The pressure pipe body 1 drives the irregular extrusion plate 12 to move, and the irregular extrusion plate 12 is clamped in the groove of the irregular insert ring 13. Since the pressure pipe body 1 is combined with the seal, the extrusion spring 11 is squeezed to provide elastic force, and the extrusion spring 11 squeezes the irregular extrusion plate 12 to fit tightly in the irregular insert ring 13, so that the pressure pipe The inside is in a sealed state, which avoids the generator duct 2 from being poorly sealed at the connection, causing leakage at the gas pressure pipe. When the gas pressure is too high, the sealing threaded rod 25 is rotated, and the sealing threaded rod 25 drives the sealing gasket 26 to move. The sealing gasket 26 releases the seal on the through hole 24, and the high-pressure gas enters the through hole 24 through the vent 27. The high-pressure gas is discharged from the through hole 24 to the atmosphere, so that the pressure pipe is vented to avoid excessive gas pressure in the pressure pipe, which may cause the pressure pipe to burst and endanger the safety of the staff.
