Abstract
The invention discloses a bidirectional guide compound compensator, comprising end joint tubes, a corrugated pipe, a left guide pipe, a right guide pipe and a middle joint pipe. The middle joint pipe is connected with the end joint pipes at two ends, through the corrugated pipe, forming a compound corrugated pipe compensator structure; the left guide pipe and the right guide pipe axially covering the corrugated pipe are arranged inside the corrugated pipe; the bidirectional guide compound compensator is further characterized in that the left guide pipe and the right guide pipe are opposite; the left end of the left guide pipe is fixedly connected to the inner wall of the left end joint pipe, the right end of the right guide pipe is fixedly connected to the inner wall of the right end joint pipe, the right end of the left guide pipe and the left end of the right guide pipe are sleeved, and a sleeved joint is provided with a seal structure. The bidirectional guide compound compensator can prevent particulate matters from entering an inner cavity of the corrugated pipe and has a bidirectional guide function.
Description
Technical field
The present invention relates to a kind of pipe safety device, specifically, relate to the compound compensator of a kind of bidirectional guide.
Background technique
The structural type of pipeline compensator is varied, has single entry type, compound type, balance type etc., and compound type compensator is all generally be connected by bellows by between middle adapter with two ends pipe nipple, forms compound compensator.The honeycomb duct axially covering bellows is provided with in the bellows of existing compound compensator, honeycomb duct set-up mode flows to along pipeline medium at bellows place, two ends respectively to arrange a honeycomb duct in the same way, although this setup can boot media circulate effectively, but there is defect: in two honeycomb ducts, one will be welded in middle adapter, middle adapter has very long distance outside pipe nipple, and during welding, manufacturability is poor; When pipeline medium has granular substance, granular substance enters bellows inner chamber from honeycomb duct and the gap location of adapter endoporus, and bellows lost efficacy because solid particle scratches, and had a strong impact on working life.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of problem that can solve honeycomb duct welding usability difference, the granular substance in medium can be avoided again to enter bellows inner chamber, the compound compensator of bidirectional guide in significant prolongation compensator working life.
The present invention is achieved through the following technical solutions technical goal.
The compound compensator of bidirectional guide, is comprised pipe nipple, bellows, left honeycomb duct, middle adapter, right honeycomb duct, is connected between described middle adapter with two ends pipe nipple by bellows, forms complex corrugated pipe collocation structure; The left honeycomb duct and right honeycomb duct that axially cover bellows is provided with in described bellows; Its improvements are: described left honeycomb duct, right honeycomb duct are set up relatively, the left end of left honeycomb duct is fixedly connected on the inwall of left-hand end adapter, the right-hand member of right honeycomb duct is fixedly connected on the inwall of right-hand end adapter, the right-hand member of left honeycomb duct, the left end fit of right honeycomb duct, suit place is provided with sealing configuration.
In said structure, the sealing configuration of described left honeycomb duct and right honeycomb duct suit place is labyrinth seal structure.
In said structure, the right-hand member of described left honeycomb duct is provided with in-flanges, and the left end of right honeycomb duct is provided with flanging; Described left honeycomb duct right-hand member in-flanges and right honeycomb duct left end flanging gap fit, form labyrinth seal structure.
The present invention compared with prior art, has following good effect:
1. left honeycomb duct, right honeycomb duct are set up relatively, and the left end of left guide shell is fixedly connected on the inwall of left-hand end adapter, and the right-hand member of right guide shell is fixedly connected on the inwall of right-hand end adapter, significantly improves welding technological properties, reduces fabricating cost; The sealing configuration of flanging in the honeycomb duct of left and right, without the need to increasing other sealing materials, significantly reduces cost of production; Also have after the honeycomb duct fit of left and right protection compensator in extreme cases bellows be not straightened and lost efficacy.
2. labyrinth seal structure protects bellows not to be etched effectively, improves working life of bellows, thus extends compound compensator working life further, reduces user cost.
3. compensator install time by MEDIA FLOW to impact, easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is I part partial enlarged drawing in Fig. 1.
Embodiment
Below with reference to the accompanying drawings and the invention will be further described in conjunction with the embodiments.
The compound compensator of bidirectional guide shown in the drawings, is comprised pipe nipple 1, bellows 2, left honeycomb duct 3, middle adapter 4, right honeycomb duct 5, is connected between middle adapter 4 with two ends pipe nipple 1 by bellows 2, forms complex corrugated pipe compensator structure; The left honeycomb duct 3 and right honeycomb duct 5 that axially cover bellows 2 is provided with in bellows 2; In the present embodiment, left honeycomb duct 3, right honeycomb duct 5 are set up relatively, and the left end of left honeycomb duct 3 is fixedly connected on the inwall of left-hand end adapter 1, and the right-hand member of right honeycomb duct 5 is fixedly connected on the inwall of right-hand end adapter 1, the right-hand member of left honeycomb duct 3 is provided with in-flanges, and the left end of right honeycomb duct 5 is provided with flanging; Left honeycomb duct 3 right-hand member in-flanges and right honeycomb duct 5 left end flanging gap fit, form labyrinth seal structure, both effective sealing protection was carried out to the inner chamber of bellows 2, have again protection compensator in extreme cases bellows 2 be not straightened and lost efficacy.
