Abstract
The utility model belongs to a device on heat network pipelines, which is used for absorbing or compensating the pipeline deformation quantity caused by hot expanding cold shrinking. The utility model is mainly composed of a press cover, a rotary body, shape fixing sealing rings, fillings, a pressing injecting head, a sliding bearing, a plane bearing, a shell and other basic components, wherein two shape fixing sealing rings are arranged in the shell, fillings are filled between the two sealing rings so as to playing double sealing efficiency. Meanwhile, the surface and the inner end surface of the rotary body are provided with the sliding bearing and the plane bearing so as to reduce the turning moment of a compensator. Meanwhile, under the condition of no air stopping temperature reduction and voltage reduction, the utility model can maintain leakage points on the compensator and the utility model has the advantages of simple structure and convenient operation.
Description
Technical field
The utility model belongs to the equipment on the heat-net-pipeline, is used to absorb or compensates the amount of deformation of pipeline because of expanding with heat and contract with cold and producing.
Background technique
At present, known old-fashioned whirl compensator mainly is made up of housing, solid of rotation, gland, seal ring and other basic part.It seals, and main pressured lid crush seal circle realizes, yet in a single day seal ring may wear to the limit, will cause seal failure, produces to leak and can not repair, influenced the ride quality of pipe network.
Summary of the invention
In order to overcome the deficiency in the old-fashioned whirl compensator sealing, the utility model provides a kind of product of alternative old-fashioned whirl compensator---can annotate sealing compound formula whirl compensator.This compensator has not only solved the problem of seal failure effectively, and can also leakage point be safeguarded being with under the warm situation with pressure.
The technological scheme that its technical problem that solves the utility model adopts is: be provided with many pressure injection heads on the circumference of housing outer surface, when compensator uses appearance to leak for a long time, this moment, pipe network did not need the desuperheat step-down of stopping the supple of gas or steam, as long as in Seal cage, inject some fillers, just can eliminate leakage to this compensator at the nearest pressure injection head of this compensator leakage point.Simultaneously placed sliding bearing between solid of rotation outer surface and shell inner surface, solid of rotation and housing interior edge face have been placed plane bearing again, and the moment of rotation of compensator is reduced again greatly.Thereby guaranteed the normal operation of pipe network.
The beneficial effects of the utility model are: this compensator has that compensation rate is big, moment of rotation is little, long service life, under the situation of desuperheat step-down of not stopping the supple of gas or steam, just can safeguard simultaneously the leakage point on this compensator, and also simple in structure, easy to operate.Thereby overcome old-fashioned whirl compensator and caused this difficult problem of seal failure because of long-term work.
Description of drawings
Accompanying drawing 1 expression can be annotated the structural type of sealing compound formula whirl compensator.
Numeral is as follows among Fig. 1:
The solid shape seal ring 6-plane bearing 7-housing 8-pressure injection head of 1-solid of rotation 2-gland 3-sliding bearing 4-filler (flexible expanded graphite) 5-(being used for annotating filler)
Embodiment
Can annotate sealing compound formula whirl compensator mainly is made up of housing, solid shape seal ring, solid of rotation, pressure injection head, filler, plane bearing, sliding bearing and other basic part.Be provided with the solid shape seal ring of twice in enclosure interior, on the circumference of housing outer surface, be provided with many pressure injection heads, by pressure injection head injection filler in the middle of two seal rings, played the effect of double seal then; When compensator used appearance to leak for a long time, this moment, pipe network did not need the desuperheat step-down of stopping the supple of gas or steam, as long as inject some fillers at the nearest pressure injection head of this compensator leakage point, just can eliminate leakage to this compensator, had guaranteed the normal operation of pipe network.Simultaneously placed sliding bearing between solid of rotation outer surface and shell inner surface, solid of rotation and housing interior edge face have been placed plane bearing again, and the moment of rotation of compensator is reduced again greatly.
Claims (2)
1, can annotate sealing compound formula whirl compensator, comprise housing, solid shape seal ring, solid of rotation, pressure injection head, filler, plane bearing, sliding bearing, gland, it is characterized in that: place solid shape seal ring and filler between solid of rotation and the housing, and filler is filled between two solid shape seal rings.
2, the sealing compound formula whirl compensator of annotating according to claim 1, it is characterized in that: pressure injection head is arranged on the circumference of housing outer surface.
