Abstract
The invention discloses a novel sealing device for a temperature shock environment testing box. The novel sealing device comprises male and female clamping grooves, heating belts and sealing strips, wherein the multiple groups of male and female clamping grooves are uniformly formed in two corresponding sealing surfaces and used for connecting and fixing the sealing surfaces, each male and female clamping groove comprises a male groove body and a female groove body, the heating belts are pasted on the two sides of each male and female clamping groove, and the sealing strips are symmetrically arranged on the outer sides of the two corresponding sealing surfaces. According to the novel sealing device for the temperature shock environment testing box, low-temperature equipment can be sealed through a conventional material, restrictive demands are not made on a user of the low-temperature equipment, and the novel sealing device has the characteristics of being simple, easy to operate, low in failure rate and the like from the aspect of use.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of New temperature shock environmental test box seal device.
Background technology
New temperature shock environmental test box seal device, in order to realize adopting liquid nitrogen refrigerating, when doing-150 DEG C and temperature below test, it is possible to effectively nacelle is sealed, it is prevented that low temperature nitrogen leaks.
When liquid nitrogen cryogenics is tested, in cabin, temperature is extremely low, and environmental test chamber seals and the material of flexibility need to be adopted to realize, so the use of the material of equipment is proposed high requirement.The mode that environmental test chamber making side adopted in the past, is usually and is used as easy consumption product by sealing member, when low-temperature test destroys encapsulant, user material is replaced.So use often equipment and technical ability to environmental simulation equipment user to propose higher requirement, manpower and financial resources are caused very big waste.
When solving the problems referred to above, many-sided exploration was also once done by domestic proof box producer.The mode such as adopting vacuum flange seals, but has the limitation of part, and the user of environmental test chamber is proposed restrictive condition or material proposes unconventional requirement.
Summary of the invention
It is an object of the invention to make up the deficiencies in the prior art, it is provided that a kind of can reduce the sealing device New temperature shock environmental test box seal device to material requirements.
To achieve these goals, the technical scheme is that, a kind of New temperature shock environmental test box seal device, including primary and secondary draw-in groove, heating tape, sealing strip；Wherein, being evenly arranged with some groups of primary and secondary draw-in grooves on two corresponding sealing surfaces, fixing for being connected by sealing surface, each primary and secondary draw-in groove all includes pilot trench and female groove；Stickup heating tape, every primary and secondary draw-in groove both sides；It is symmetrical arranged sealing strip outside two corresponding sealing surfaces.
The invention has the beneficial effects as follows: adopt conventional material can realize the sealing to cryogenic equipment, and cryogenic equipment user will not be proposed restrictive requirement.From use will, succinctly, the feature such as easy operation, failure rate is low.
Accompanying drawing explanation
Fig. 1 is the application schematic diagram of the present invention.
Fig. 2 is present configuration schematic diagram.
In figure, 1-primary and secondary draw-in groove, 2-heating tape, 3-sealing strip.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described further.
A kind of New temperature shock environmental test box seal device, it uses as it is shown in figure 1, structure is as in figure 2 it is shown, include primary and secondary draw-in groove 1, heating tape 2, sealing strip 3；Wherein, being evenly arranged with some groups of primary and secondary draw-in grooves 1 on two corresponding sealing surfaces, fixing for being connected by sealing surface, each primary and secondary draw-in groove 1 all includes pilot trench and female groove；Stickup heating tape, every primary and secondary draw-in groove 1 both sides 2, opens heating tape 2, is heated, to keep the activity of sealing strip 3 during work；It is symmetrical arranged sealing strip 3 outside two corresponding sealing surfaces；For strengthening the sealing property of two sealing surfaces of correspondence.
Above embodiments of the invention are explained in detail, above-mentioned embodiment is only most highly preferred embodiment of the invention, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, it is also possible to make various change under the premise without departing from present inventive concept.
