Problems solved by technology

[0006] The second installation requires that the central axes of the holes of the two connected pipes should be aligned, otherwise the rubber ring may be broken after the installation is completed, and the flow area will be affected
[0007] The third pipe clamp connection method cannot dynamically adjust the clamp compression force according to the fluid pressure in the pipe

Embodiment Construction

[0023] See attached figure 1 , an inflatable pipeline connection clamp, which includes: a plug 1, a clamp 2, a bolt 3 and an air bag 4;

[0024] The clamp 2 is two metal half rings, and the two metal half rings are connected by two bolts 3 to form a complete ring body, and the middle position of each metal half ring is provided with a radial threaded through hole;

[0025] The airbag 4 includes: an airbag body 5 and an airbag inflation nozzle 6; the airbag body 5 is a strip structure, one end of which is pointed, and the other end is provided with a U-shaped gap. Located in the U-shaped notch at the other end; the airbag inflation nozzle 6 is arranged on the airbag body 5;

[0026] Under normal circumstances, the inside of the airbag 4 is filled with gas with a certain pressure, so that it can reach a full state, so that it can be conveniently placed in the installation groove of the inner wall of the metal half ring in the clamp 2; the airbag inflation nozzle 6 is aligned wi...

Abstract

The invention belongs to the technical field of structural design, and particularly relates to a pipeline connecting clamp hoop, which has the technical scheme that the inflating type pipeline connecting clamp hoop comprises a plug (1), a clamp hoop (2), a screw bolt (3) and an air bag (4), wherein the clamp hoop (2) is connected by the screw bolt (3), the air bag (4) is plated in the clamp hoop (2) after being inflated, and the plug (1) is arranged in a threaded hole of the clamp hoop (2). The inflating type pipeline connecting clamp hoop can be used for completely pasting the outer surfaces of the two ends of a pipeline, so the sealing is ensured, the pressure of the clamp hoop on the pipeline can be changed according to the inflating pressure of the air bag, in addition, the vibration resistance capability is realized, the impact force from each direction can be absorbed, and meanwhile, the contraction and expansion resistance capability is realized. Compared with the welding connecting mode, a flange connecting mode and an ordinary clamp hoop connecting mode, the inflating type pipeline connecting clamp hoop has the advantage that the stability of a pipeline system is improved.

Description

technical field [0001] The invention belongs to the technical field of structural design, and in particular relates to a pipe connection clamp. Background technique [0002] The grooved pipe fitting connection technology is also called the clamp connection technology. It is the main technology for the current liquid and gas pipeline connection. After years of development and application, it has gradually replaced the two traditional pipeline connection methods of flange and welding, and has been recognized by the market. generally accepted. [0003] Grooved connection pipe fittings include two major categories of products: ①The pipe fittings that play the role of connection and sealing include rigid joints, flexible joints, mechanical tees and grooved flanges; ②The pipe fittings that play the role of connection transition include elbows, tees, Cross, reducer, blind plate, etc. Among them, the groove connection pipe fittings that play the role of connection and sealing main...
