The utility model discloses improve corrugated expansion ware's product structure, provide a double-deck corrugated expansion ware of vacuum insulation, prevent the heat conduction between inside medium and the ambient temperature to the produced drawback of corrugated expansion ware outside parcel thermal insulation material has been avoided.
Description
Technical Field
The utility model relates to a corrugated compensator field, especially a double-deck corrugated compensator of adiabatic type in vacuum.
Background
The corrugated pipe compensator is a sealed pressure-bearing flexible element, plays the roles of compensating displacement, absorbing deformation and vibration in a pipeline conveying system, and is particularly used for compensating expansion and contraction of pipelines in heat supply and refrigeration pipelines. In this kind of heating and refrigeration piping system usually, in order to prevent heat conduction between medium and the ambient temperature in the pipeline, can wrap up one deck thermal insulation material in order to stop thermal radiation conduction outside the pipeline, because the appearance of bellows is annular ripple form, the thermal insulation material often can run into the trough of bellows in the bellows working deformation process, the accumulation in the day and the month can all be filled up with whole trough part even, the effective deformation of bellows has been hindered, this compensation ability of bellows compensator when having just influenced the pipeline operation greatly.

In order to solve the technical problem, the utility model discloses a double-deck ripple compensator of adiabatic type in vacuum, including inlayer bellows and outer bellows, inlayer bellows and outer bellows both ends are connected through first crown plate and second crown plate respectively and are sealed the formation die cavity, one side of die cavity is equipped with the vacuum valve that is used for the die cavity evacuation.
The utility model discloses in, the first crown plate outside is equipped with first flange.
The utility model discloses in, the second ring plate outside is equipped with the second flange.
The utility model discloses in, the inlayer bellows is double-deck nonrust corrugated steel pipe.
The utility model discloses in, outer bellows is double-deck nonrust corrugated steel pipe.
Has the advantages that: the utility model discloses improve corrugated expansion ware's product structure, provide a double-deck corrugated expansion ware of vacuum insulation, prevent the heat conduction between inside medium and the ambient temperature to the produced drawback of corrugated expansion ware outside parcel thermal insulation material has been avoided.
Drawings
These and/or other advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings and the following detailed description.
Fig. 1 is a schematic sectional view.
Detailed Description
Example (b):
as shown in fig. 1, the present embodiment provides a vacuum insulation type double-layer corrugated compensator, which includes an inner-layer corrugated pipe 1, an outer-layer corrugated pipe 2, a first ring plate 3, a second ring plate 4, a cavity 5, a vacuum valve 6, a first flange 7, and a second flange 8;
specifically, the corrugated compensator comprises an inner-layer corrugated pipe 1 and an outer-layer corrugated pipe 2, two ends of the inner-layer corrugated pipe 1 and two ends of the outer-layer corrugated pipe 2 are respectively connected and sealed through a first annular plate 3 and a second annular plate 4 to form a cavity 5, and a vacuum valve 6 for vacuumizing the cavity is arranged on one side of the cavity 5. In this embodiment, the first ring plate 3 and the second ring plate 4 are welded at two ends of the inner corrugated tube 1 and the outer corrugated tube 2, respectively.
In this embodiment, a first flange 7 is provided outside the first annular plate 3.
In this embodiment, a second flange 8 is provided outside the second ring plate 4.
In this embodiment, the inner corrugated tube 1 is a double-layer stainless steel corrugated tube.
In this embodiment, the outer corrugated tube 2 is a double-layer stainless steel corrugated tube.
The process flow of the corrugated pipe compensator of the embodiment is as follows:
manufacturing an outer-layer corrugated pipe and an inner-layer corrugated pipe:
finish rolling stainless steel plate, blanking, coiling, longitudinal seam welding, tube blank sleeving, solution treatment, hydraulic corrugation forming and notching.
Assembling the corrugated pipe compensator:
welding an inner-layer corrugated pipe and a welding ring into an assembly, testing pressure, welding and welding the inner-layer corrugated pipe assembly and an outer-layer corrugated pipe, vacuumizing, welding a flange and testing pressure.
In the embodiment, the compensator is designed into a structure consisting of an inner corrugated pipe and an outer corrugated pipe, the inner corrugated pipe is connected with a pipeline to be communicated with a medium, the outer corrugated pipe is contacted with the external environment, and the inner corrugated pipe and the outer corrugated pipe are welded through a ring plate to form a closed cavity. And then the closed cavity between the two layers of corrugated pipes is vacuumized through a vacuum valve, and the heat cannot be conducted in vacuum, so that the aim of preventing the mutual heat conduction between the internal medium and the ambient temperature is fulfilled.
The utility model provides a thought and method of the double-deck ripple compensator of adiabatic type in vacuum, the method and the way that specifically realize this technical scheme are many, above only the utility model discloses a preferred embodiment should point out, to ordinary technical personnel in this technical field, do not deviate from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements and moist decorations, these improvements should also regard as with moist decorations the utility model discloses a protection scope. All the components not specified in the present embodiment can be realized by the prior art.
