Abstract
The utility model relates to a sleeve cylinder type pipeline compensator provided with an outer sleeve pipe and an inner pipe, wherein, the inner pipe is positioned in the outer sleeve pipe and can relatively extend and retreat, and a check ring, an asbestos square packing, a sealing ring, an asbestos square packing and an outer pressing ring are successively arranged between the outer sleeve pipe and the inner pipe; the outer sleeve pipe outside the sealing ring is provided with a plurality of colloid sealant injection holes and sealing screws. The utility model adopts colloid sealant as the sealing ring, and is additionally provided with an anti-skinning mechanism, so that the utility model has the advantages of good sealing property, abrasion resistance., long service life and high safety performance. As an ideal pipeline compensator, the utility model is suitable for being installed in heating power pipelines to play a function of pipeline swelling-shrinkage compensation.
Description
The utility model relates to a kind of pipe coupling technology, specifically a kind of telescopic pipeline compensator.
As everyone knows, have the flexible phenomenon that causes because of expanding with heat and contract with cold in the pipeline that the long distance of industries such as electric power, oil, chemical industry is carried.In order to regulate the flexible of pipeline, the suitable position at pipeline that has is processed into " U " type structure, utilizes " U " type structure to carry out the bit shift compensation of pipeline, this structure waste material, cost height, maintenance difficult; Pipeline compensator is used in connecting at the pipe joint position of having, high pressure pipe line breathing compensator as patent CN2085457U announcement, it is by steel tubing in different shapes, telescopic pipe and be loaded on Sealing, the spring propulsion of two pipe portions, thread regulator and clamp structure constitute, with the adjustment of can stretching of expanding with heat and contract with cold, this compensator structure complexity, cost height; The employing bellows that also has carries out flexible compensation, and is poor for applicability, and working life is short.
The purpose of this utility model is exactly in order to overcome the deficiency of existing various pipeline compensators, a kind of simple in structure, good seal performance to be provided, and is wear-resistant, the telescopic pipeline compensator of long service life.
For achieving the above object, a kind of telescopic pipeline compensator, it is provided with outer sleeve, interior pipe, interior pipe is positioned at outer sleeve, telescopic displacement relatively, it is characterized in that being provided with successively between outer sleeve and the interior pipe seal ring, asbestos packing, the outer trim ring of back-up ring, asbestos packing, the formation of colloid sealing compound, correspondingly be provided with some colloid sealing compound hand-holes and sealing screw on the outer sleeve in the seal ring outside.
The utility model has been set up the seal ring that the colloid sealing compound is formed in the middle of the oil immersion asbestos packing, and the colloid sealing compound is high temperature resistant, anti-aging, and expansion coefficient is big, plays good seal action between interior pipe and outer sleeve.Thereby, improved the sealability of pipeline compensator, the working life of having improved pipeline compensator greatly.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model structural representation, also is embodiment's schematic representation.
As can be seen from Figure 1, a kind of telescopic pipeline compensator, it is provided with outer sleeve 1, interior pipe 2, interior pipe 2 parts are positioned at outer sleeve 1, their the other end respectively with pipeline in pipeline be connected and fixed, outer sleeve and interior pipe can with pipeline expand with heat and contract with cold and relative telescopic displacement, the breathing of compensation conduit.Be provided with back-up ring 3, asbestos packing 4, seal ring 5, asbestos packing 4, outer trim ring 8 between the utility model outer sleeve 1 and the interior pipe 2 successively.The outer sleeve inner wall of back-up ring 3 inboards is established a boss, blocking back-up ring does not move inwards, outer trim ring 8 is fixed on the outer sleeve one end inwall by some screws 7, fixedly asbestos packing 4 and seal ring 5 are mobile by back-up ring 3 and outer trim ring 8 like this, make them stably between outer sleeve 1 and interior pipe 2, seal, when guaranteeing outer sleeve and interior pipe relative displacement, do not reveal.The utility model asbestos packing 4 adopts oil immersion to handle, and seal ring 5 is made up of the colloid sealing compound, is provided with some sealing compound hand-holes on outer sleeve 1, during assembling, injects the colloid sealing compound from hand-hole and then uses screw 6 fixing seals.The colloid sealing compound forms seal ring 5 between about asbestos packing, it is high temperature resistant, and is anti-aging, expansion coefficient is big, can seal up outer sleeve 1 and interior pipe 2 the sealability height firmly with expanding with heat and contract with cold of pipeline, long service life, the performance and the working life of having improved pipeline compensator.
Pipe 2 and outer sleeve 1 break away from when the utility model shrinks in order to prevent pipeline, have also set up an escapement.Be provided with several in the processing of outer sleeve 1 and interior pipe 2 outsides respectively and draw ear 9, the middle connection with pipe and outer sleeve in guaranteeing by pull bar 10 is unlikely disengaging.Pull bar 10 plays the anticreep effect on the one hand, play the guiding role during displacement on the other hand.End at pull bar 10 can be processed with adjusting screw, and the relative length of regulating tie bar adapts the relative displacement of itself and interior pipe and outer sleeve.
The utility model is owing to adopt the colloid sealing compound to make seal ring, and set up escapement, and good seal performance is wear-resistant, long service life, and the Safety performance height is a kind of desirable pipeline compensator.Be suitable for being installed in the compensating action that plays pipeline breathing in the heating power pipeline.
Claims (2)
1, a kind of telescopic pipeline compensator, it is provided with outer sleeve, interior pipe, interior pipe is positioned at outer sleeve, telescopic displacement relatively, it is characterized in that being provided with successively between outer sleeve and the interior pipe seal ring, asbestos packing, the outer trim ring of back-up ring, asbestos packing, the formation of colloid sealing compound, correspondingly be provided with some colloid sealing compound hand-holes and sealing screw on the outer sleeve in the seal ring outside.
2, telescopic pipeline compensator as claimed in claim 1 is characterized in that said outer sleeve and the interior pipe outside is respectively equipped with several and draws ear, connects to form escapement by pull bar, and an end of pull bar also is provided with adjusting screw.
