Description

Novel sealed Pivot area clamp

Technical Field

The utility model relates to the field of pipeline connection, in particular to a novel sealing type Pivot band clamp.

Background

The clamp is a connecting device for connecting pipe fittings, valves and pipeline fittings with grooves. In the exhaust system and the power system of the automobile, the metal hose is accepted and used by the industry at home and abroad as an upgrade product of the traditional corrugated pipe. The metal hose is connected in various modes, and is welded directly or connected through a flange in a relatively conventional mode, but the direct welding mode causes more trouble and heavy workload in future maintenance or replacement, and the flange connection does not solve the problems of heaviness, difficult installation, difficult disassembly and time consumption although avoiding the problem. Researchers have therefore devised clips to replace flanged connections.

According to the different connection objects, the connection requirements are different, and the clamp structure is also various, such as a V-shaped clamp, a G-shaped clamp, a band clamp and the like. For some pipe connections with high tightness requirements, conventional band clamps do not meet the tightness requirements.

Accordingly, there is a need for a new and improved sealing type Pivot band clamp that solves the above-mentioned problems.
