Abstract
The utility model relates to a bellow type elastic pipe joint, which is composed of connectors, bellow pipe and a bush. The utility model is provided with two connectors respectively positioned on both ends of the bellow pipe. The bush is sheathed in the bellow pipe and both ends are welded together with both ends of the bellow pipe. The utility model better solves the problems of easy impurity generation, particle deposition and insertion of iron dust foreign matter in the bellow pipe in the prior art. The bellow type elastic pipe joint is suitable to be used by various pipes.
Description
The utility model relates to a kind of flexible pipe joint that uses that causes because of expanding with heat and contract with cold for the compensator fluid pipeline, particularly a kind of bellow type springy pipeline joint that neck bush is arranged.
At present, generally the springy pipeline joint of Shi Yonging is made of flange, bellows, and the two ends of bellows are welded on two flanges.Mainly there is following technical problem in it, easily produces impurity, particle deposition and iron filings foreign matter inlay card in the bellows, causes that the springy pipeline joint telescopicing performance descends, and pipeline is not smooth.
The purpose of this utility model just is at the deficiencies in the prior art part, and a kind of bellow type elastomeric joint is provided, and it not only can guarantee the compensation conduit displacement, and can reduce impurity, foreign matter deposition and the inlay card at the bellows place effectively.
The purpose of this utility model is achieved through the following technical solutions.Described pipe joint is made of coupling, bellows, lining.Coupling has two, lays respectively at the bellows two ends.Lining is contained in the bellows, and its two ends and bellows two ends weld together.
Described lining is the volute that the lath spiral form is rolled into tubulose.
The utility model compared with prior art has following technique effect: the variation of the displacement that (1) can compensation conduit causes because of expanding with heat and contract with cold, can reduce impurity, foreign matter deposition and inlay card again effectively at the bellows place, guarantee the unimpeded of pipeline, improve the elasticity of bellows.(2) when variations in line pressure, metallic coil can produce radially buffering, thereby alleviates influence of vibration.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Described pipe joint is made of coupling 1, bellows 2, lining 3.Bellows 2 is that metallic material is made, and being radially has the size rule to change, axial wavy scalable component, and its internal surface is fluted.Coupling 1 is a standard piece of selecting outfit according to the installation requirement of pipeline.The two ends of bellows 2 are welded on respectively on the coupling 1.Lining 3 is to be rolled into tubular body by high-quality elasticity, corrosion resistant metal lath spiral form, and its winding direction should be consistent with the direction of fluid in the pipeline.Its two ends and bellows 2 are welded as a whole, and can freely stretch with bellows 2, also can do radial displacement in right amount.
Claims (2)
1. a bellow type springy pipeline joint is made of coupling, bellows, lining, it is characterized in that coupling has two, lays respectively at the two ends of bellows, and lining is contained in the bellows, and its two ends and bellows two ends weld together.
2. according to the described bellow type springy pipeline joint of claim 1, it is characterized in that lining is the volute that is rolled into tubulose by the lath spiral form.
