Abstract
The utility model discloses an axial compensation reinforced connecting structure of a corrugated pipe compensator, which is arranged in a circular-pipe-shaped case. Both ends of a corrugated pipe are outwards extending axial flanging structures which are welded and connected with a small flange at the left end and a large flange at the right end to form the axial compensation connecting structure, the outer wall of the large flange is fixedly connected in the inner wall of the case, a circular ring sleeve is sheathed on the outer wall of the axial flanging at the left end of the corrugated pipe to be connected with the small flange in a sealed way for forming the reinforced connecting structure, and a process tank is arranged near welding joints arranged on the outer wall of the small flange and the inner wall of the large flange. The axial compensation reinforced connecting structure has reasonable welding structure and good welding fusion degree of welding seams, obviously enhances the welding seam connection strength and prolongs the service life of the compensator.
Description
Technical field
The utility model relates to a kind of pipe connecting structure, and specifically, the utility model relates to the linkage structure of a kind of thin-wall corrugated tube and heavy wall flange.
Background technique
In liquid, gas transmission pipeline, often dispose corrugated expansion joint with the axial displacement and the stress that absorb or the compensation pipeline produces because of physical change, corrugated expansion joint can satisfy the compensation of pipeline requirement fully in the actual application.But, prior art products is damaged because of the jointing at bellows two ends is easy to crack, trace it to its cause, the thicker part of bellows and two ends tube wall that is thin-walled in the prior art directly is connected, because of the wall thickness great disparity is bigger, welded structure is unreasonable, causes the welded joint degree of fusion bad, internal stress is bigger, so leakage accident easily takes place prior art products.
Summary of the invention
The utility model is at the deficiencies in the prior art, propose a kind of welded joint structure rationally, make easily, the corrugated expansion joint nose balance of long service life strengthens linkage structure.
The utility model is achieved through the following technical solutions technical goal.
The corrugated expansion joint nose balance is strengthened linkage structure, and it is located in the round tubular housing; The bellows two ends are overhanging axial turnup structures, are welded to connect formation nose balance linkage structure with the small flange plate of left end, the big flange plate of right-hand member, and described big flange plate outer wall is fixedly connected in the outer casing inner wall; Its improvements are: circular ring set is linked in the outer wall of bellows left end shaft to flange, is tightly connected in the lump with small flange plate, constitutes to strengthen linkage structure; The welded joint left side is provided with technology groove on the described small flange plate outer wall; Welded joint the right is provided with technology groove on the described big flange plate inwall.
In the said structure, described technology groove can be arc groove, vee gutter or rectangular slot; Described technology groove is 0.9～1.1 times of bellows thickness L1 to the axial distance L2 of bevel for welding; The degree of depth L3 of described technology groove is 1/4～1/3 of bellows thickness L1.
The utility model compared with prior art has following good effect:
1. simple in structure, make easily..
2. be provided with technology groove near welded joint place, bellows two ends, wall thickness is close when making the welding of welded joint place, bellows two ends, and reasonable welding structure has reduced welding stress.
3. the bellows left end shaft equates the circular ring set of wall thickness to the outer wall fit of flange with the axial flange of bellows, has improved weld seam welding degree of fusion, significantly strengthens the weld seam join strength, has improved compensator working life.
