Abstract
The utility model relates to a metal hose of an external spring protective tube, which belongs to the field of compensating and connecting components for pipelines. A spring protective tube (2) is externally sleeved on a wire mesh sleeve (1) of the metal hose, and the end of the spring protective tube (2) is welded with an end hoop (3). The pitch begins at the smallest pitch which is equal to the wire radius, and gradually increases to make transition to the middle of the metal hose from the welding end. As the spring protective tube (2) utilizes the protection function of the elastic force, the end hoop of the metal hose cannot generate bending deformation and the corresponding alternating stress, and the metal hose is difficult to generate fatigue breakage and leakage. The metal hose has obvious effect and a simple structure, is easy to implement, and has low cost.
Description
Technical field
The utility model belongs to the compensation connector element field that pipeline is used, and relates to a kind of metallic hose of external spring pillar.
Background technique
In the prior art, metallic hose is by metal bellows, the wire sets of overcoat and adapter assembly are by end cuff assembly welding be combined into, deficiency is, under some special operating modes, space and mounting point are limited bigger, the relative deformation of the size of requirement metallic hose is big, the vibration of also wanting absorption equipment to produce simultaneously, therefore very easily fatigue fracture occurs and leak, and mostly occur in the position, high temperature oxidation district of end cuff assembly welding combination, reason is, metallic hose power effect by bending at first occurs in the position, high temperature oxidation district of end cuff assembly welding combination, and this position can produce very macrobending distortion and corresponding alternating stress, because not control, and the intensity at position, high temperature oxidation district is low, therefore easily fatigue fracture occurs at this position.
Summary of the invention
The technical problem that solves:
A kind of metallic hose of external spring pillar is provided; can overcome the deficiencies in the prior art; the termination and the end cuff that are enclosed within the spring pillar on the wire sets of metallic hose weld together; thereby protect the position, high temperature oxidation district of end cuff assembly welding combination with the elastic force of spring; make it can not produce crooked bending and corresponding alternating stress, be not prone to fatigue fracture.
The technological scheme that adopts:
A kind of metallic hose of external spring pillar, wire sets and adapter assembly with metal bellows, overcoat, and be combined as a whole by end cuff assembly welding, it is characterized in that: outer casing spring pillar on the wire sets, length according to metallic hose needs, supporting spring pillar of overcoat, its two ends weld together with two end cuffs of metallic hose respectively; Perhaps the length according to metallic hose needs, two supporting spring pillars of overcoat, two relative terminations of two spring pillars weld together with two end cuffs of metallic hose respectively, two of two spring pillars in opposite directions the termination be free end, and should keep certain spacing L between two free ends, spacing L should guarantee fully that corresponding metallic hose section has the leeway of free deformation therebetween, and two free ends can not interfere with each other.
Beneficial effect:
Because the protective action of spring pillar; can control the bending deflection and the corresponding alternating stress at the position, high temperature oxidation district of end cuff assembly welding combination; metallic hose power effect by bending is at first from stage casing ripple generation free deformation; then gradually on the ripple in both sides extend to spring pillar except that cuff position, end; and corresponding alternating stress reduces gradually; because the effect and the protection of the elastic force of spring pillar; strained metallic hose can in time obtain restorable ability; and the cuff position, end of metallic hose can not produce bending deflection and corresponding alternating stress; be not prone to fatigue fracture and leak, effect is obvious; simple in structure; easily implement.

Embodiment
Further explanation in detail in conjunction with the accompanying drawings;
As shown in Figure 1, outer casing spring pillar 2 on the wire sets 1 of metallic hose need according to the length of metallic hose, when metallic hose shorter, during as the 300mm left and right sides, supporting spring pillar 2 of overcoat, its two ends welds together with two end cuffs 3 of metallic hose respectively; Perhaps the length according to metallic hose needs, when metallic hose longer, during as the 1000mm left and right sides, two supporting spring pillars 2 of overcoat, each long 200～300mm, two relative terminations of two spring pillars 2 weld together with two end cuffs 3 of metallic hose respectively, two of two spring pillars 2 in opposite directions the termination be free end, and should keep certain spacing L between two free ends, spacing L should guarantee fully that corresponding metallic hose section has the leeway of free deformation therebetween, and can not produce between two free ends and interfere with each other; Because during metallic hose is made, the wire sets 1 of metal bellows 4, overcoat and adapter assembly 5 are that the external port assembly welding by end cuff 3 is combined as a whole, therefore, the termination of described spring pillar 2 and end cuff 3 weld together, and are meant that the termination of spring pillar 2 and the inner port of end cuff 3 weld together;
Described supporting spring pillar 2, its internal diameter should with the external diameter coupling of the wire sets 1 of metallic hose, should guarantee fully that wire sets 1 can freely stretch in spring pillar 2, and spring pillar 2 is from termination that the end cuff 3 of itself and metallic hose welds together, its pitch equals its line directly from minimum, and the formula that strengthens gradually is to the transition of the stage casing of metallic hose.
Claims (2)
1. the metallic hose of an external spring pillar, wire sets and adapter assembly with metal bellows, overcoat, and be combined as a whole by end cuff assembly welding, it is characterized in that: outer casing spring pillar on the wire sets, length according to metallic hose needs, supporting spring pillar of overcoat, its two ends weld together with two end cuffs of metallic hose respectively; Perhaps the length according to metallic hose needs, two supporting spring pillars of overcoat, two relative terminations of two spring pillars weld together with two end cuffs of metallic hose respectively, two of two spring pillars in opposite directions the termination be free end, and should keep certain spacing L between two free ends, spacing L should guarantee fully that corresponding metallic hose section has the leeway of free deformation therebetween, and two free ends can not interfere with each other.
2. the metallic hose of a kind of external spring pillar according to claim 1, it is characterized in that: supporting spring pillar (2), its internal diameter should with the external diameter coupling of the wire sets (1) of metallic hose, should guarantee fully that wire sets (1) can freely stretch in spring pillar (2), and spring pillar (2) is from termination that the end cuff (3) of itself and metallic hose welds together, its pitch equals its line directly from minimum, and the formula that strengthens gradually is to the transition of the stage casing of metallic hose.
