Abstract

The utility model discloses a kind of vacuum sealing tube telescopic with adaptive guard function; including sealing ring, sealing flange, inner tube, outer tube; said inner tube and outer tube expansion fit; the abutting end of the outer tube sets sealing flange; sealing ring is set on the inside of the sealing flange, and the outer wall sealing of the sealing ring and inner tube is slidably matched.The mutual expansion fit relation of inner tube of the present utility model and outer tube, can digester tube deformation, it is more convenient to be changed by the instrument and meter maintenance in expansion fit relation pipeline, connect the sealing flange used between inner tube and outer tube sealing ring is fixed and extruded, so as to be sealed to inner tube and outer tube, the cooperation stroke of inner tube and outer tube is big, it is allowed to which the deflection of pipeline is bigger.The utility model is simple in construction, and connection and convenient disassembly, good sealing effect, adjustment amount is big, to being connected with instrument and meter with the sealing pipeline of anti-stress damage with very big Practical significance.

Description

A kind of vacuum sealing tube telescopic with adaptive guard function
Technical field
The utility model belongs to metallurgical, technical field of chemical, be related to it is a kind of it is simple in construction, easy to use have from Adapt to the vacuum sealing tube telescopic of defencive function.
Background technology
There is more vacuum pipe in metallurgical, chemical industry, pipeline is long and needs to install various valves on pipeline Instrument, pipeline are influenceed in the case where expanding with heat and contract with cold by temperature change, or have certain media flow, in the case of mechanical oscillation, pipe Road produce stress, valve, instrument is squeezed and is stretched, not only influence pipe-line system sealing, cause miopragia and Failure, serious can also make valve, instrument damage.Meanwhile when valve, instrument need maintaining and changed on pipeline, rigidity Connection causes the dismounting of accessory and installation to become extremely difficult.Therefore, it is necessary to which a kind of have high vacuum seal ability and can be with Flexible device, compensate pipeline extension and eliminate stress, remove, installation when by stretching reserve operating space, adapt to because by The adjustment that power and device size deviation need, so as to protect the devices such as valve, instrument, convenient pipe-line system Maintenance and Repair, ensure The reliability service and service life of pipe-line system.Existing pipeline expansion device(Compensator)It is used to the liquid mediums such as water, it is impossible to Condition of high vacuum degree pipeline is adapted to, and is deformed by thin-walled material natural resiliency to realize, stroke is small, and easily produces tired Labor is damaged, the also clashing and breaking by outside maloperation, and manufacturing process is complicated, and cost is higher.Therefore, research and development one kind has adaptive guard The vacuum sealing tube telescopic of function is significant.
The content of the invention
The purpose of this utility model, which is to provide, a kind of simple in construction, easy to use has the true of adaptive guard function Empty seal pipe telescopic.
The purpose of this utility model is achieved in that including sealing ring, sealing flange, inner tube, outer tube, said inner tube With outer tube expansion fit, the abutting end of the outer tube sets sealing flange, sealing ring, institute is set on the inside of the sealing flange The outer wall sealing for stating sealing ring and inner tube is slidably matched.
The mutual expansion fit relation of inner tube of the present utility model and outer tube, can digester tube deformation, avoid pipeline Damage of the stress caused by deformation to pipeline, changed more by the instrument and meter maintenance in expansion fit relation pipeline It is convenient, the sealing flange used is connected between inner tube and outer tube sealing ring is fixed and extruded, so as to inner tube and outside Sleeve pipe is sealed, good sealing effect, ensures vacuum state, inner tube and outward appearance use stainless steel tube, have anti-corrosion capability, no The cooperation stroke of easy damage of colliding with, inner tube and outer tube is big, it is allowed to which the deflection of pipeline is bigger.The utility model structure Simply, connection and convenient disassembly, good sealing effect, adjustment amount is big, to the sealing pipe with instrument and meter and anti-stress damage Road connection has very big Practical significance.
Brief description of the drawings
Fig. 1 is that the utility model master cuts open structure chart;
Fig. 2 is the utility model three-dimensional structure diagram;
In figure:1- adpting flanges, 2- sealing rings, 3- sealing flanges, 31- determine flange, 32- loose flanges, 4- inner tubes, outside 5- Sleeve pipe.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the utility model must not be added in any way With limitation, any changes and modifications made based on the utility model training centre, the scope of protection of the utility model is belonged to.
As shown in Figure 1 and 2, the utility model include sealing ring 2, sealing flange 3, inner tube 4, outer tube 5, said inner tube 4 with The expansion fit of outer tube 5, the abutting end of the outer tube 5 set sealing flange 3, and the inner side of sealing flange 3 sets sealing ring 2, the sealing ring 2 and the outside wall surface sealing of inner tube 4 are slidably matched.
The remote abutting end of said inner tube 4 and outer tube 5 is respectively provided with adpting flange 1.
The sealing flange 3 includes determining flange 31 and loose flange 32, described to determine flange 31 and be fixedly installed on outer tube 5 End, the loose flange 32 set groove, the groove with determining the bolt connection of flange 31, the medial surface of the loose flange 32 Place sets sealing ring 2.
Limited step is set in said inner tube 4, and the external diameter of limited step is more than the external diameter of outer tube 5.
The sealing ring 2 is arranged to foamed silastic sealing ring.
Heavy platform and the end of inner tube 4 is set to coordinate on the adpting flange 1.
The end of heavy platform and outer tube 5 is set to coordinate on the adpting flange 1.
Said inner tube 4 and outer tube 5 are arranged to the smooth stainless steel tube in surface.
Utility model works principle and the course of work:
The mutual expansion fit relation of inner tube 4 of the present utility model and outer tube 5, can digester tube deformation, avoid pipe Damage of the stress to pipeline caused by road deformation, changed more by the instrument and meter maintenance in expansion fit relation pipeline Add conveniently, the sealing flange 3 used is connected between inner tube 4 and outer tube 5 sealing ring 2 is fixed and extruded, so as to internally Pipe 4 is sealed with outer tube 5, good sealing effect, ensures vacuum state, inner tube and outward appearance use stainless steel tube, have anti-corrosion Erosion ability, it is not easy to which the cooperation stroke of damage of colliding with, inner tube and outer tube is big, it is allowed to which the deflection of pipeline is bigger, the He of inner tube 4 The both ends of outer tube 5 set adpting flange 1, make this structure be easier to match connection with pipeline, using more convenient.
