Abstract
The utility model relates to a compensator of a no-trust high-sealed casing pipe, wherein, a left device body 1, a connection pipe 4, a right device body 8 and a guiding seat 11 of which are fixedly connected in turn in a sealing way; expansion pipes 5 are positioned in the left device body 1, the connection pipe 4, the right device body 8 and the guiding seat 11. Sealing devices are arranged between the expansion pipe 5 and the left device body 1, the right device body 8 and the guiding seat 11. The utility model is installed on a heating power direct pipeline and can absorb the heat swell increment of the pipeline. Thus, the thrust force of the fixing bracket form the fluid pressure in the pipeline can be eliminated. The compensator has the advantages of low cost, small ground occupation and convenient installation.
Description
The utility model relates to heat enginnering machinery, specifically is a kind of no thrust high sealing sleeve compensator.
In the heat enginnering system, be used for the effect of the flowing medium of heat in the pipeline, make pipeline generation thermal expansion.The thermal expansion of pipeline produces thrust to fixed support, influences installation, the service property (quality) of equipment.
The purpose of this utility model is equipment quality to be caused the problem of adverse effect at the thermal expansion of heat distribution pipeline, a kind of thermal expansion amount that can extraction duct is provided, thereby avoid that fixed support is subjected to extra thrust in the pipeline, keep equilibrium of forces in the pipeline to improve the no thrust high sealing sleeve compensator of equipment quality.
The technical solution of the utility model is: no thrust high sealing sleeve compensator comprises left body, connecting tube, right body, telescopic pipe, guide holder.Left side body, connecting tube, guide holder seal successively and are connected.Telescopic pipe is positioned at left body, connecting tube, right body and guide holder.Telescopic pipe has an annular solid outward.The annular cross-sectional area of annular solid equates with sectional area in the pipe.Be provided with seal arrangement between telescopic pipe and left body, right body, the guide holder.Be provided with guide ring between telescopic pipe and left body, the guide holder.Have aperture on the telescopic pipe of annular solid right side.
During work, because telescopic pipe can move in left body, right body vertically, therefore can avoid the pipeline fixed support to be subjected to the thrust of pipeline,, guarantee the installation and the service property (quality) of equipment simultaneously owing to strict Sealing Device because of thermal expansion and the generation of tube fluid pressure.
The utility model is reasonable in design, and cost is low, and floor space is little, and is easy for installation, and compensation rate corresponds to actual needs.
Accompanying drawing is a tectonic maps of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing:
No thrust high sealing sleeve compensator comprises left body 1, connecting tube 4, right body 8, telescopic pipe 5, guide holder 11.A left side body 1, connecting tube 4, right body 8, guide holder 11 seals successively and are connected, and telescopic pipe 5 is positioned at left body 1, at adapter 4, right body 8 and guide holder 11.An annular solid 15 is arranged outside the telescopic pipe 5.The annular cross-sectional area of annular solid 15 equates with sectional area in the pipe.Be provided with seal apparatus between telescopic pipe 5 and left body 1, right body 8, the guide holder 11.Be provided with guide ring 2 and guide ring 12 between telescopic pipe 5 and left body 1, the guide holder 11.Have aperture 16 on the annular solid 15 right side telescopic pipes 5.
Seal arrangement between telescopic pipe 5 and the right body 8 is made of intermediate seal ring 6 and seal ring 7; Seal arrangement in the middle of telescopic pipe 5 and left body 1, the guide holder 11 is made of intermediate seal ring 9 and seal ring 10.
On the shell of left side body 1, right body 8, guide holder 11 material feeding cylinder 3 is housed all.Baffle plate 13 is equipped with in the right side of guide ring 12.
Whole no thrust high sealing sleeve compensator is bearing on the guiding trestle 14.Compensator can be connected with pipeline with welding or flange.
The material of seal ring 7 and seal ring 10 is decided according to operating temperature, is filled polytetrafluoroethylene when operating temperature t≤280 ℃, is the asbestos composite material during t≤350 ℃, is spheroidal graphite cast iron during t≤400 ℃.Intermediate seal ring 6, intermediate seal ring 7 is for being the sealing material of matrix with graphite.Can in equipment operation, sealing material be filled in the seal arrangement by material feeding cylinder 3, need not to stop production equipment is safeguarded.
