Abstract
The utility model discloses an automatic length compensation device for a gas pipeline. The automatic length compensation device for the gas pipeline is characterized by comprising an outer sliding sleeve pipe and an inner sliding sleeve pipe, wherein a plurality of sealing grooves are axially formed in the inner wall of the outer sliding sleeve pipe or the outer periphery of the inner sliding sleeve pipe at intervals, and sealing rings are arranged in the sealing grooves so that the inner sliding sleeve pipe can be matched with the outer sliding sleeve pipe in a sealed mode when the inner sliding sleeve pipe is inserted into the outer sliding sleeve pipe. Flanges are respectively arranged on the outer periphery of the outer sliding sleeve pipe and the outer periphery of the inner sliding sleeve pipe, the outer sliding sleeve pipe is connected with the inner sliding sleeve pipe due to the fact that positioning guide screw rods are arranged on the flanges, one end of each positioning guide screw rod is fixedly connected with the inner sliding sleeve pipe or the outer sliding sleeve pipe, and the other end of each positioning guide screw rod is matched with the outer sliding sleeve pipe or the inner sliding sleeve pipe in a sliding mode. When temperature difference changes, the strain amount is automatically regulated through the sleeve pipes, internal stress does not exist, the pipeline or equipment is not damaged, and the automatic length compensation device for the gas pipeline can be used for length compensation in the pipeline with a short distance, low-medium pressure and large temperature difference.
Description
Technical field
The utility model relates to gas pipeline length automatic compensator.
Background technique
Gas pipeline is when being subject to difference variation, because thermal stretching or temperature stress cause pipe deforming or destruction, at present for the mode that solves pipe deforming, mainly contain following two kinds: the one, by the bellows mode, the normally used condition of bellows is on low pressure and high temperature pipe, bellows is in use to rely on the distortion of bellows to mend the length change of tasting by the thermal expansion generation, pipeline exists very large internal stress, and the working pressure of bellows is also little, working pressure is large, and the tube wall of bellows will be thickeied; The 2nd, by U-shaped tube road mode: usually use on long distance pipeline, it is larger that its takes up an area space.
The model utility content
Technical problem to be solved in the utility model is the gas pipeline length automatic compensator that internal stress free in a kind of using process is provided, can damage pipeline or equipment for the technical problem existed in above-mentioned prior art.
The technological scheme that the utility model adopts is: gas pipeline length automatic compensator, it is characterized in that it comprises outer sliding sleeve pipe and inner sliding sleeve pipe, be arranged at intervals with vertically a plurality of seal grooves at the inwall of described outer sliding sleeve pipe or in the periphery of described inner sliding sleeve pipe, be provided with in seal groove that when seal ring makes the inner sliding sleeve pipe insert in the outer sliding sleeve pipe, both are sealed and matched, periphery at outer sliding sleeve pipe and inner sliding sleeve pipe is provided with flange, the outer sliding sleeve pipe is connected by the positioning and guiding screw rod is set at flange with the inner sliding sleeve pipe, one end of described positioning and guiding screw rod is fixedly connected with inner sliding sleeve pipe or outer sliding sleeve pipe, the other end and outer sliding sleeve pipe or inner sliding sleeve pipe slippage configuration.
By technique scheme, the external diameter of described positioning screw is less than the internal diameter of the flange hole arranged on outer sliding sleeve pipe or inner sliding sleeve pipe.
By technique scheme, be arranged at intervals with vertically a plurality of supporting annular grooves at the inwall of outer sliding sleeve pipe or at the outer wall of inner sliding sleeve pipe, be provided with supporting ring in each supporting annular groove.
By technique scheme, described seal ring and support ring are alternately laid.
By technique scheme, described seal ring is 3-5, and supporting ring is 2-4.
The obtained beneficial effect of the utility model is:
1, the utility model, when being subject to difference variation, can be regulated strain capacity voluntarily by sleeve pipe, and its internal stress free can not damage pipeline or equipment, the length compensation in the pipeline that can be used for short distance, hang down middle pressure, Temperature Difference Ratio is larger;
2, in the utility model, supporting ring is for guaranteeing that the position of pipeline can not be offset, and seal ring assurance pipeline gas can not revealed, and positioning screw has guaranteed the safety problem of gas pipeline length auto-compensation.
The accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Embodiment
