Abstract
The utility model provides a metal corrugated pipe end connector with multiple protection copper bushes and aims to solve the problem that the whole service life of metal corrugated pipes is substantially shortened due to the fact that welding heads of existing metal corrugated pipe end connectors, which are used for being welded to metal corrugated pipe ends, are free of coatings. The connector comprises a tubular welding head, wherein a connection end of the welding head and a connection end of a metal corrugated pipe are welded, the outer wall of the welding head sleeves a plug-in connector, a ring-shaped groove which faces towards one side of the metal corrugated pipe is arranged between the plug-in connector and the outer wall of the welding head, the protection copper bushes are inserted into the ring-shaped groove, and free ends of the protection copper bushes wrap the connection end of the metal corrugated pipe. According to the metal corrugated pipe end connector with the multiple protection copper bushes, the whole service life of a hose is effectively prolonged, the phenomenon of stress concentration of a connection portion of the metal corrugated pipe is greatly eliminated, an anti-bending property of the connection portion of the metal corrugated pipe can be greatly improved, and the condition that irregular installation of the metal corrugated pipe affects the connection portion of the metal corrugated pipe is completely eradicated.
Description
Technical field
The utility model relates to Bellows Technology field, specifically, relates to a kind of wavy metal tube end connection joint that is provided with multiple-protection copper sheathing.
Background technique
At first, people are stitched into the structure of tubulose with animal skin, to adapt to produce the needs of struggle.Passed through quite long period, to 17th century last years of a century, ten thousand Dare Gai Jin brothers of Holland have made the canvas hose of longitudinal stitching, in fire-fighting business at that time, are widely adopted.Afterwards, along with rubber appearance in the international market and the development of sulfuration process thereof, sebific duct and the sebific duct with the fabric such as wire or rope made of hemp armouring had come out.But, the high temperature media of some steam, hot blast class in engineering ' liquid hydrogen, the cryogenic media of liquid oxygen, liquid helium class, gasoline, kerosene, corrosive media such as acid, alkali ... if, carry with sebific duct, of course not.Particularly, under high temperature condition, its safety reliability is just more difficult to ensure and has demonstrate,proved.
Therefore, people gradually focus on metal tube aspect attention, change the geometrical shape of metal tube, make its inner and outer surface produce corresponding ripple.Like this, it had both had the same flexible of same sebific duct, meanwhile, had again high temperature resistant, low temperature resistant, ageing-resistant, decay resistance.So, produced as the metal bellows of metallic hose body like this.
Metal bellows, as sensing element, damper element, compensating element, seal element, valve element and pipeline connecting parts, is widely used in the fields such as automatic control and measurement instrument, vacuum technique, mechanical industry, power industry, communications and transportation and atomic energy industry.
Existing wavy metal tube end connection joint, the soldered splice that itself and wavy metal tube end weld, due to without coating, becomes anticorrosion comparatively weak part, and metal bellows whole service life is significantly reduced.
Model utility content
The utility model is in order to solve existing wavy metal tube end connection joint, the soldered splice that itself and wavy metal tube end weld is due to without coating, become anticorrosion comparatively weak part, the deficiency that metal bellows whole service life is significantly reduced, provides a kind of wavy metal tube end connection joint that is provided with multiple-protection copper sheathing.
The technical problem of the required solution of the utility model, can be achieved through the following technical solutions:
A kind of wavy metal tube end connection joint that is provided with multiple-protection copper sheathing; comprise soldered splice in a tubular form; the connecting end of described soldered splice and the welding of the connecting end of metal bellows; it is characterized in that: the outer wall of described soldered splice is set with inserted sleeve; between described inserted sleeve and soldered splice outer wall, be provided with the circular groove towards metal bellows one side; in described circular groove, be inserted with protection copper sheathing, the connecting end of the free end coated metal bellows of described protection copper sheathing.
In the utility model, between the free end of described protection copper sheathing and the connecting end of metal bellows, be provided with flexible pipe coating, described flexible pipe coating is sleeved on outside the connecting end of metal bellows.
Described flexible pipe coating is flexible pipe PVC coating.
In the utility model, the outer wall of described inserted sleeve is provided with outside thread, so that connect.
The wavy metal tube end connection joint that is provided with multiple-protection copper sheathing of the present utility model; by installing multiple protective copper sheathing additional; avoid welded header to become anticorrosion weak part; effectively promote flexible pipe whole service life; greatly eliminate metal bellows connection part stress concentration phenomenon while being subject to external force bending due to metal bellows; can protect especially soldered splice weld seam; can greatly improve metal bellows connection part bending resistance, stopping when metal bellows is lack of standardization to be installed and used affects metal bellows connection part.
Accompanying drawing explanation
Further illustrate the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make technological means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Purport of the present utility model is, by existing wavy metal tube end is connected to the analysis by the basic structure of transferring between joint and metal bellows, find that the soldered splice that welds with wavy metal tube end is due to without coating, become anticorrosion comparatively weak part, the problem that metal bellows whole service life is significantly reduced, provides a kind of wavy metal tube end connection joint that is provided with multiple-protection copper sheathing by the utility model.
Referring to Fig. 1; the wavy metal tube end connection joint that is provided with multiple-protection copper sheathing of the present utility model; comprise soldered splice 4 in a tubular form; the connecting end welding of the connecting end of soldered splice 4 and metal bellows 1; the outer wall of soldered splice 1 is set with inserted sleeve 5; between inserted sleeve 5 and soldered splice 4 outer walls, be provided with the circular groove 6 towards metal bellows 1 one sides; in circular groove 6, be inserted with protection copper sheathing 3; protect the insertion end 31 of copper sheathing 3 to insert in circular groove 6, the connecting end of the free end 32 coated metal bellowss 1 of protection copper sheathing 3.
In the utility model, between the protection free end 32 of copper sheathing 3 and the connecting end of metal bellows 1, be also provided with flexible pipe coating 2, flexible pipe coating 2 is sleeved on outside the connecting end of metal bellows 1, and flexible pipe coating 2 is preferably and adopts flexible pipe PVC coating.In addition, in the utility model, the outer wall of inserted sleeve 5 is also provided with outside thread 51, so that connect.To the utility model wavy metal tube end, connection is simply described with the connection procedure of joint below:
First the connecting end of the connecting end of metal bellows 1 and soldered splice 4 is welded; at periphery coating flexible pipe PVC coating the extrusion moulding of metal bellows 1 connecting end; the free end 32 of protection copper sheathing 3 is inserted to metal bellows 1; by stable holding flexible pipe PVC coating after free end 32 punching presses; finally free end 31 is being inserted to circular groove 6, clamping soldered splice 4.
