Problems solved by technology

There are many deficiencies in these two connection methods: if the electric welding connection method is used, the construction period is long, the sealing effect is unstable, one-time welding is not conducive to pipeline maintenance, and electric welding is highly dependent on power supply, which is not conducive to safety under special conditions; The connection between the pipe and the pipe does not match, and the welding or flange connection cannot be done without changing the diameter of the pipe; regardless of the welding method or the flange method, continuous splicing is required, which requires high technical skills of skilled workers

Abstract

The invention discloses a heavy-caliber O-shaped pipeline locking device. The heavy-caliber O-shaped pipeline locking device is characterized by comprising a fastening ring and a sealing platform, wherein the fastening ring is provided with a fastening interface; a bolt hole is arranged on the fastening interface; at least one pair of strip grooves around the fastening ring is arranged on the inner surface of the fastening ring; the strip grooves extend from the fastening interface at one end of the fastening ring to form the sealing platform; and the strip grooves are communicated with the other end of the sealing platform through the sealing platform and are provided with sealing rings. Compared with the prior art, the heavy-caliber O-shaped pipeline locking device has the advantages of strong toughness, convenience in assembly and disassembly, short construction period, high efficiency, convenience and quickness in pipeline maintenance, electroless operation and high safety and guarantee.

Description

【Technical field】 [0001] The invention relates to a large diameter O-shaped pipeline locking device. 【Background technique】 [0002] At present, the connection between large-diameter metal pipes basically adopts electric welding connection or flange connection. There are many deficiencies in these two connection methods: if the electric welding connection method is used, the construction period is long, the sealing effect is unstable, one-time welding is not conducive to pipeline maintenance, and electric welding is highly dependent on power supply, which is not conducive to safety under special conditions; The connection between the pipe and the pipe does not match, and the welding or flange connection cannot be done without changing the diameter of the pipe; no matter whether the welding method or the flange method is used, continuous splicing is required, which requires high technical skills of skilled workers. 【Content of invention】 [0003] The present invention prov...
