Abstract
The utility model relates to a practical telescopic device which can perform effective protection on a pipeline system during displacement motion. The practical telescopic device comprises a V-shaped dual-flexible-soft-joint mechanism, wherein a No.1 elbow, a No.2 elbow, a No.1 groove connecting joint, a No.2 groove connecting joint, a left flexible soft joint (I), a right flexible soft joint (II) and a No.3 elbow are arranged on the left side and the right side of the V-shaped mechanism respectively. The practical telescopic device can provide multi-direction large-amplitude displacement compensation for a pipeline when displacement occurs by adopting the special V-shaped arrangement way and the dual-flexible-soft-joint mechanism.
Description
The utility model relates to a kind ofly carries out the effectively practical expansion device of protection to pipe-line system when tackling displacement movement, form by the two flexible soft connector displacement mechanisms of space " V-arrangement " layout, " V-arrangement " mechanism left side is respectively by elbow (1) number, the groove jointing 1. number, the flexible soft connector in left side (I) is formed; " V-arrangement " mechanism right side is respectively by elbow (2) number, the groove jointing 2. number, the flexible soft connector in right side (II) is formed; " V-arrangement " mechanism left and right sides is connected with elbow (3) number realization by the flexible soft connector in the left and right sides.
At present; owing to inquire into not enough to research and relevant protective measure that pipe-line system is destroyed; the general both at home and abroad pipe-line system that laterally or vertically is provided with in the localized metallic FlexbleJoint guard bit shifting movement that adopts; but because that no matter impurity such as the as easy as rolling off a log deposition dirt of transverse metal FlexbleJoint make in system maintenance or piping displacement compensation and isolation effect is all not good; and metal corrugation compensator is limited for the adaptability of displacement movement; very easily be torn when running into bigger displacement; and As time goes on, metal corrugation compensator is easy to deform and makes that descending appearred in the compensation ability of pipeline when displacement took place.Pipe-line system makes the afunction of its original piping design or part lose because destroy when displacement takes place greatly, and this will cause heavy losses to the security of the lives and property.Therefore to displacement when big the protection of pipe-line system in fields such as commerce, industry important meaning is arranged.
In order to tackle displacement destruction to pipe-line system when big, this practicality expansion device will provide pipe-line system displacement protection, in the time of protection pipe-line system and relevant main equipment, the secondary disaster of bringing because of pipe-line system destruction be dropped to minimum level.
The technological scheme that its technical problem that solves the utility model adopts is: the arrangement that utilizes practical expansion device " V-arrangement ", and the two flexible soft connector structures of " V-arrangement " in-house layout, effective bit shift compensation when realizing the piping displacement motion alleviates because the destruction that displacement movement causes pipe-line system.
Should further set forth by the practicality expansion device below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3,4 pairs in accompanying drawing.

The horizontal mobile schematic representation of accompanying drawing 4 practical expansion devices
(1) number among the figure, (2) number are elbow; 1., number be the groove jointing 2.; (I), (II) be flexible soft connector, (3) number are elbow.
Shown in accompanying drawing 1, accompanying drawing 2, the practical expansion device of the utility model mechanism is made up of symmetrical " V-arrangement " mechanism respectively." V-arrangement " mechanism left side is respectively by elbow (1) number, the groove jointing 1. number, the flexible soft connector in left side (I) is formed; " V-arrangement " mechanism right side is respectively by elbow (2) number, the groove jointing 2. number, the flexible soft connector in right side (II) is formed; Elbow (3) number is connected with the flexible soft connector in the left and right sides.Each parts is arranged respectively in the following manner: " V-arrangement " mechanism left side elbow (1) number and flexible soft connector (I) are number by welding or screwed connection, flexible soft connector (I) number number is connected by welding or screwed connection and elbow (3), number has located the groove jointing at elbow (1) and 1. number has been connected with required protection pipe-line system left end; " V-arrangement " mechanism right side elbow (2) number and flexible soft connector (II) are number by welding or screwed connection; flexible soft connector (II) number number is connected by welding or screwed connection and elbow (3), number has located the groove jointing at elbow (2) and 2. number has been connected with required protection pipe-line system right-hand member.
The working principle of this practical expansion device is to utilize practical expansion device " V-arrangement " arrangement of pipeline, the two flexible soft connector of " V-arrangement " section allows the synchronous or asynchronous multidirectional motion of left and right sides pipeline respectively, realizes that effective bit shift compensation and the vibration in the piping displacement motion isolated.The structure of the flexible soft connector in the left and right sides allows practical expansion device to realize vertically moving and laterally moving, and overcome the deficiency of the limited and pure linear arrangement of single flexible soft connector compensation rate, the isolation that well makes pipeline adapt to displacement movement and realize pipe vibration.
As shown in Figure 3, when length travel occurs, owing to arrange the particular design of flexible soft connector about " V-arrangement " mechanism, there is bigger mobile range in the left and right sides, allow practical expansion device both sides pipeline to have bigger substantially horizontal displacement, practical expansion device will realize vertically moving bit shift compensation shown in accompanying drawing 3 left and right sides dotted line movement locus this moment; When lateral displacement occurs, because the special construction of the flexible soft connector in the left and right sides can allow the adaptivity under the lateral displacement to move, allow practical expansion device both sides pipeline to exist the dislocation of bigger Vertical direction to move, this moment, practical expansion device will be as shown in Figure 4, and lower edge dotted line movement locus is realized horizontal moving displacement compensation on " V-arrangement " mechanism left and right sides pipeline.
" V-arrangement " arrangement that this practical expansion device is special, and two flexible soft connector structure can provide multidirectional bit shift compensation significantly to pipeline when displacement takes place.This compensation device has rational in infrastructure, need not to take big quantity space, is easy to advantages such as on-the-spot installation and later maintenance.
