Description

A kind of high-strength abrasion-proof compensator

Technical field

The utility model relates to pipeline compensator technical field, especially a kind of high-strength abrasion-proof compensator.

Background technique

Compensator is traditionally also expansion joint or telescopic joint, belongs to a kind of compensating element, utilizes the effective of its operative body Dilatation, the change in size or compensation pipes generated with absorption line, conduit, container etc. by the reasons such as expanding with heat and contract with cold are led The axial of pipe, container etc., transverse direction and angular displacement, it can also be used to noise-and-vibration-reduction.

In pipe-line system, since tube wall is under the long-term impact of gas, meeting accelerated wear test, due to traditional ripple compensation The rigidity of device is insufficient, and one of main failure forms are exactly formation abrasion, cause production accident.

Summary of the invention

(1) the technical issues of solving

The utility model is insufficient according to prior art, and provides a kind of wear-resisting compensator, reaches and improves rub resistance effect Fruit, the effect for increasing compensator rigidity and prolonging the service life.

(2) technical solution

A kind of high-strength abrasion-proof compensator, it is characterised in that: include: first sleeve, second sleeve, spring, spring stack and Overlay cladding, the first sleeve are connected with second sleeve by the spring stack, and the body portion of the spring stack passes through described The inner surface of the interior porose area of spring, the first sleeve is equipped with overlay cladding.

Further, the shaft diameter of the spring stack is 2--3mm smaller than the diameter of bore of the spring.

Further, the both ends contact site of the first sleeve and second sleeve and the spring is designed with for accommodating institute State the groove of spring, depth 8-10mm.

Further, sealing ring is additionally provided in the first sleeve.

(3) beneficial effect

Compared with the existing technology, the utility model has following the utility model has the advantages that the prior art is ripple elastomer, by outer Be easy when forcing contracting it is askew fall, material is mostly stainless steel, and poor flexibility, intensity is low, and the service life is short, and the utility model is using spring Add spring rod structure, rigidity is also increased while guaranteeing elasticity, service life improves.

It is that elastomer is directly contacted with gas in the prior art, accelerated corrosion aging, the utility model is equipped with overlay cladding, by In there is overlay cladding, the wearability of first sleeve inner surface is improved, the service life extends.

So the utility model has many advantages, such as intensity height, wear-resistant, long service life.

Specific embodiment

Below in conjunction with the attached drawing in the embodiments of the present invention, to the technical solution in the embodiments of the present invention It is clearly and completely described, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than complete The embodiment in portion.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work Under the premise of every other embodiment obtained, fall within the protection scope of the utility model.

Embodiment 1:

A kind of high-strength abrasion-proof compensator as shown in Figure 1:, comprising: first sleeve 1, second sleeve 2, spring 3, spring stack 4 With overlay cladding 6, first sleeve 1 is connected with second sleeve 2 by spring stack 4, and the body portion of spring stack 4 passes through the spring 3 Interior porose area, the shaft diameter of spring stack 4 is 2--3mm smaller than the diameter of bore of spring 3, and built-up welding is on the surface or edge of workpiece The welding procedure for carrying out one layer of the deposition function metals layer such as wear-resisting, anti-corrosion, heat-resisting, wear-resisting, anti-corrosion, heat-resisting spy is welded in view of heap Property, in order to improve the wearability of compensator, it is equipped with overlay cladding 6 in the inner surface of first sleeve 1, in order to improve the sealing of compensator Property, sealing ring 5 is additionally provided in first sleeve 1.

As shown in Figure 2: the both ends contact site of first sleeve 1 and second sleeve 2 and spring 3 is designed with depth 8-10mm's Groove can prevent spring 3 from teetertottering for accommodating spring 3, the groove.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
