Problems solved by technology

Cement pipes, cast iron pipes, and lead pipelines cannot be welded; the pipeline system cannot completely cut off the medium due to internal leakage of the valve; when the surface of the pipeline is severely corroded, it is generally solved by punching clips and half joints, but the original treatment The process punching can not meet the requirements; using the half joint, because the surface of the pipeline is corroded and uneven, the seal of the half joint sealing ring is not tight, and the leakage treatment effect is not good; especially when the temperature of the medium conveyed by the pipeline is high, the rubber sealing ring is used, shortened lifespan
Increased the difficulty of maintenance work, causing hidden dangers to safe and civilized production, and increased costs

Embodiment Construction

[0007] The outer edge 9 of the tank body 5 of the present invention forms an extrusion cavity 12, and the bolt 3 is fixedly installed on the outer edge 9, and the extrusion sealing ring 4 is placed in the extrusion cavity 12, and the extrusion sealing ring 4 continues An extrusion cover 8 is installed, and the end of the extrusion cover 8 is pushed on the extrusion sealing ring 4. There is an extrusion force arm 2 on the extrusion cover 8, and a through hole is opened on the extrusion force arm 2. The bolt 3 Through the through hole and fastened by the nut 1; the side wall of the tank body 5 has a pressure discharge port 10 communicating with the tank inner cavity 6, and the pressure discharge port 10 is covered with a pressure discharge cock 11 through a screw thread.

[0008] The tank body 5 of the present invention has a tank inner cavity 6, an extrusion sealing ring 4 is an extrusion cavity 7 in the middle, and an extrusion cover 8 has a through cavity 13, and the tank inne...

Abstract

The invention discloses a rapid connection leakage repairing device, and belongs to the technical field of pipe connection. The rapid connection leakage repairing device can carry out on-site leakage repairing when leakage points appear in the pipeline, the pipeline does not need to be detached and replaced, and the leakage points can be directly sealed; an extrusion cavity is defined by the outer edge of a tank body, a bolt is fixedly mounted on the outer edge, an extrusion seal ring is arranged in the extrusion cavity, an extrusion cover is mounted outside the extrusion seal ring continuously, the end of the extrusion cover abuts against the extrusion seal ring, an extrusion stress arm is arranged on the extrusion cover, a through hole is formed in the extrusion stress arm, the bolt penetrates the through hole and is fastened through a nut, and a pressure exhaust opening communicating with a tank body inner cavity is formed in the side wall of the tank body, and is provided with a pressure exhaust rotary plug through a thread cover. Pipeline connection and leakage treatment are rapid, the service life is long, performance is stable, safety and reliability are achieved, and the device is particularly suitable for industrial production pipeline connection and leakage treatment overhauling.

Description

technical field [0001] The invention belongs to the technical field of pipe connection. Background technique [0002] At present, industrial pipelines such as power plants, paper mills, chemical plants, cement plants, and boilers are widely used and have many types. Due to geological subsidence, corrosion, mechanical force and other reasons, the pipeline breaks and corrosion leaks. Cement pipes, cast iron pipes, and lead pipelines cannot be welded; the pipeline system cannot completely cut off the medium due to internal leakage of the valve; when the surface of the pipeline is severely corroded, it is generally solved by punching clips and half joints, but the original treatment The process punching can not meet the requirements; using the half joint, because the surface of the pipeline is corroded and uneven, the seal of the half joint sealing ring is not tight, and the leakage treatment effect is not good; especially when the temperature of the medium conveyed by the pipe...
