Abstract
The utility model relates to a flexible compensator for a medium conveying pipeline which generates displacement due to the deformation caused by the change of cold and heat. The utility model adopts a static sealing system which is composed of an H-shaped tubular sealing member, a metallic expansion pipe which is assembled outside the sealing member and a flange which is connected with the sealing member in a tightly pressed way by screw nails. Therefore, the utility model has the advantages of strong capacity of bearing pressure, efficient leakage prevention, good sealing effect, fewer maintenance frequencies, fewer fixing brackets and low expenses.
Description
The utility model relates to a kind of expansion compensation device, particularly flexible compensation device.It is applicable to the various pipelines of media such as gas transmission, oil transportation, water delivery.
For the pipeline that compensates fed sheet of a media changes caused displacement deformation because of cold and hot the grade, need a kind of telescopic compensation device.Having announced a kind of notification number on the Chinese patent communique is CN2035421U " flexible telescopic compensator ".The structure of this compensator is that an outer sleeve is set on a straight tube; outer sleeve one end is connected with a straight tube rigidity; the other end is fixed on the support; and be connected in the seal protection circle on the support; be equipped with Sealing; retainer ring presses down tight seal at the pressure of spring, and being connected to of outer sleeve and another straight tube flexibly connected.By this structure, can compensate the fed sheet of a media pipeline because of cold and hot variation cause the relative displacement of joint, and make it to be in sealing state.But this compensator adopts the dynamic seal (packing) system, makes it to produce certain frictional force, thereby fixed support need be set, and processing, assembly technology are had relatively high expectations, and has leakage phenomenon to take place in the time of also.
The purpose of this utility model is to be to provide a kind of flexible compensation device, and it adopts the static sealing system, can prevent from effectively to leak, and good sealing effect, and can reduce fixed support.
Its concrete solution is: be set with Sealing on long connecting tube, and the external mounting of Sealing has the metal expansion pipe with flexibility, it is fixedlyed connected with supported flange, by screw, flange Sealing is compressed sealing, constitutes the static sealing system.Simultaneously, outer telescopic pipe is set in outside the telescopic pipe of flexible metal, fixedlys connected with supported flange, and interior telescopic pipe is set in outside the telescopic pipe of flexible metal, and its end is fixedlyed connected with supported flange, and the other end inserts among the outer telescopic pipe.But Sealing is a tubulose, and its two ends have flange plate, is " worker " font.When pipeline causes that because of cold and hot variation distortion produces displacement, the connecting tube that can link to each other with pipeline by compensator drives Sealing, and flexible metal telescopic pipe and inside and outside telescopic pipe are done relative displacement, so that the displacement deformation of compensation pipeline, and make it to be in all the time sealing state.
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings.
Accompanying drawing be the flexible compensation device partly cut open plan view.
In the accompanying drawings, be welded with fastening flange (2) on the long connecting tube (1) that is connected with the fed sheet of a media pipeline welding, be welded with fastening flange (10) on the connecting tube (11).Flanged dish in two ends and the tubular seal (5) that is " worker " font are made by rubber material, and it is sleeved on the long connecting tube (1).And metal expansion pipe (8) is a flexible metal conduit, is assemblied in Sealing (5) outside, and its two ends are welded as a whole with supported flange (3) and supported flange (9) respectively, not only can protect Sealing (5), and have pressure-bearing and leading role again.Simultaneously, on supported flange (3), be welded with and be set in the outside outer telescopic pipe (4) of metal expansion pipe (8), be set in metal expansion pipe (8) outside and be welded with on the supported flange (9), and an end inserts the interior telescopic pipe (7) within the outer telescopic pipe (4).Compress and be connected with fastening flange (2), (10) by the flange plate of screw (12), constitute two static sealing systems supported flange (3), (9) and Sealing (5) two ends.Stay bolt (6) connects two static sealing systems by nut, can play the guiding interconnect function.
The utility model is owing to adopt the static sealing system, and it is by the tubular seal of " worker " font and be sleeved on the flexible metal telescopic pipe of Sealing outside and compress flange connecting by screw and Sealing and form.So not only bearing capacity is good for it, and can prevent from effectively to leak, good sealing effect, and can reduce maintenance frequency, significantly reduce fixed support, cost saving.
Claims (3)
1, a kind of flexible compensation device, it comprises connecting tube, sealing system, it is characterized in that being set with on the long connecting tube (1) Sealing (5), and the external mounting of Sealing (5) has flexible metal telescopic pipe (8), it and supported flange (3), (9) fixedly connected, and by screw (12) and supported flange (3), (9) with Sealing (5) and fastening flange (2), (10) compress and be tightly connected, constitute the static sealing system, the outer telescopic pipe (4) that is set in simultaneously outside the flexible metal telescopic pipe (8) is fixedlyed connected with supported flange (3), and be sleeved on interior telescopic pipe (7) outside the flexible metal telescopic pipe (8), the one end is fixedlyed connected with supported flange (9), and the other end inserts within the outer telescopic pipe (4).
