Problems solved by technology

[0002] The traditional way to connect the pipe ends of pipe fittings is through flange connection. The speed of flange connection is slow, the process is complicated, and it is easy to damage the galvanized layer and paint layer on the surface of the pipe fittings.
At the same time, in order to ensure the tightness of the flange connection, a welding machine must be used to weld the connection between the flange and the pipe fittings. This welding method is not only uneconomical, but also has hidden dangers of safety and pollution.
Furthermore, the flange connection also increases the difficulty for future maintenance

Abstract

The invention discloses a groove clamping hoop type pipeline joint in the technical field of pipe joints. When used for connecting pipe fittings, the groove clamping hoop type pipeline joint has the advantages of quickness, simplicity and convenience, reliability, safety, economy, vibration isolation, no pollution and convenient maintenance. The groove clamping hoop type pipeline joint comprises two semicircle arciform clamping hoops, and two ends of each semicircle arciform clamping hoop are provided with a fastening bolt connecting lug protruding outwards respectively; the lower edges along the two lateral faces of the semicircle arciform clamping hoops are provided with flanges extending downwards respectively; a groove is arranged between the two flanges, and the two semicircle arciform clamping hoops are jogged with each other to form a seal washer mounting groove; a seal washer can be mounted in the seal washer mounting groove in a matching mode; and two fastening pieces are used for fastening tightly the lugs of the two semicircle arciform clamping hoops.

Description

technical field [0001] The invention belongs to the technical field of pipe joints, in particular to a groove clamp type pipe joint. Background technique [0002] The traditional way to connect the pipe ends of pipe fittings is through flange connection. The speed of flange connection is slow, the process is complicated, and it is easy to damage the galvanized layer and paint layer on the surface of the pipe fittings. At the same time, in order to ensure the tightness of the flange connection, a welding machine must be used to weld the connection between the flange and the pipe fittings. This welding method is not only uneconomical, but also has potential safety and pollution risks. Furthermore, the flange connection also increases the difficulty for future maintenance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a grooved clamp type pipeline joint, which is fast, simple, reliable, safe, economical, vibratio...
