Abstract
The utility model belongs to a double-way pipe compensator which can overcome the heat expansion and cold contraction of steel pipes, mainly composed of a pipeline, an outer sleeve pipe, a pressing ring, filling, a filling support, a flange, etc. Different sealing material can be select ed according to the conditions of medium and pressure in the pipeline. The utility model has the advantages of great axial compensating capacity, small ground occupation, easy fabrication, etc.
Description
The utility model relates to a kind of device that steel pipe expands with heat and contract with cold that overcomes, particularly a kind of two-way pipeline compensator.
At present, on the problem that the solution steel pipe expands with heat and contract with cold, the measure of extensively adopting one both at home and abroad is to use the type expansion bend, it exists phenomenons such as floor space is big, the pressure loss is big, compensation ability is little, two are to use corrugated expansion joint, and its compensation ability is little, withstand voltage properties is poor, manufacturing complexity etc.
The purpose of this utility model just provides a kind of two-way pipeline compensator that can overcome above-mentioned deficiency.
In order to realize above-mentioned task, two-way pipeline compensator of the present utility model, be made up of pipeline, outer sleeve, trim ring, filler, filler holder, flange etc., pipeline is divided into two-part in sleeve pipe, and the two ends of sleeve pipe contact by the packing seal that flange, trim ring compress with pipeline respectively.
Inboard, two ends at sleeve pipe is respectively equipped with the filler holder.
The outside of sleeve two ends are respectively equipped with the flange that is solidified as a whole with it.
Between the two ends of sleeve pipe and the pipeline stuffing box packing is housed.
That pipeline compensator of the present utility model has is simple in structure, manufacturing is easy, applied widely, floor space is little, offer the pipeline characteristics such as the compensation rate that produces axial displacement is big of expanding with heat and contract with cold.The stuffing box packing that can install different performance according to the size of difference of the medium in the pipeline and pressure additional reaches the purpose of sealing.This pipeline compensator can be designed to various specification as required.
Fig. 1 is the structural representation of the two-way pipeline compensator of the utility model;
Further specify the structure and the use condition of two-way pipeline compensator below in conjunction with accompanying drawing, two-way pipeline compensator as shown in the figure is made up of pipeline (1), outer sleeve (2), trim ring (6), filler (5), filler holder (7), flange (3,4) etc., pipeline (1) is divided into two-part in sleeve pipe (2), leave suitable distance between two-part, the two ends of sleeve pipe (2) respectively with pipeline (1) by flange (3,4), compress trim ring (6), trim ring (6) compresses the effect that filler (5) reaches sealing again.Also be respectively equipped with filler holder (7) in the inboard, two ends of sleeve pipe (2), be used for holding compacted filler (5).Two ends, sleeve pipe (2) outside are respectively equipped with the flange (4) that is solidified as a whole with sleeve pipe (2).Flange (3), trim ring (6) are enclosed within the outside of pipeline (1), pipeline (1) can be in sleeve pipe (2) axial stretching.
Claims (4)
1, a kind of two-way pipeline compensator, form by pipeline, outer sleeve, trim ring, filler, filler holder, flange etc., it is characterized in that pipeline (1) is divided into two-part in sleeve pipe (2), the two ends of sleeve pipe (2) contact by filler (5) sealing that flange (3,4), trim ring (6) compress with pipeline (1) respectively.
2, two-way pipeline compensator as claimed in claim 1 is characterized in that being respectively equipped with filler holder (7) in the inboard, two ends of sleeve pipe (2).
3, two-way pipeline compensator as claimed in claim 1 is characterized in that two ends, sleeve pipe (2) outside are respectively equipped with the flange (4) that is solidified as a whole with it.
4, two-way pipeline compensator as claimed in claim 1 is characterized in that between the two ends of sleeve pipe (2) and the pipeline (1) stuffing box packing (5) being arranged.
