Abstract
The utility model discloses a high-efficient thermal-insulated vacuum hose comprises hose body and the mounting flange who sets up at hose body both ends. The hose body comprises inlayer connecting pipe, interior bellows, outer bellows and outer connecting pipe, and the surface of interior bellows sets up the inlayer net cover, and the surface of outer bellows sets up outer net cover, and outer connecting pipe sets up between bellows and the outer bellows including, installs the evacuating device interface on the end of outer connecting pipe, can be bled to the vacuum state in the outer connecting pipe. The outer layer connecting pipe is a multi-layer heat insulation pipe. Interior bellows and outer bellows are soft nonrust steel pipe. The utility model discloses an inside and outside two-layer bellows will need be taken out into the connecting pipe protection of high vacuum state to install the evacuating device interface on the connecting pipe, make things convenient for the evacuation. The utility model discloses a comparatively soft bellows has realized the hose effect, makes things convenient for on-the-spot assembly.
Description
Technical Field
The utility model relates to the technical field of machinery, more specifically say, relate to high-efficient thermal-insulated vacuum hose.
Background
The transportation pipeline or the switching pipeline is common equipment in industry, and under some special environments, a vacuum or vacuum-like environment needs to be realized in the transportation pipeline, and the temporary extraction is difficult to realize. The pipeline under the vacuum state can be convenient for the trace measurement, can insulate against heat more effectively, compares with the special tank wagon of transportation usefulness, and when the material was transported, the pipeline that just needs to be transported was in the state of high vacuum.
At present, the heat insulation pipeline adopted in the market is generally a hard pipeline in order to realize a vacuum pumping state, and is difficult to correct when being used and assembled on site, so that the serious inconvenience in use can be caused.
Disclosure of Invention
The purpose of the invention is as follows: the utility model aims at the not enough and defect of prior art, provide high-efficient thermal-insulated vacuum hose, the utility model discloses a two bellows will need take out into the connecting pipe protection of high vacuum state, install the evacuating device interface on the connecting pipe, make things convenient for the evacuation to adopt comparatively soft bellows, realized the hose effect, make things convenient for on-the-spot assembly.
The technical scheme is as follows: in order to realize the above purpose, the utility model discloses the technical scheme who adopts is: the high-efficiency heat-insulation vacuum hose consists of a hose body and mounting flanges arranged at two ends of the hose body. The hose body comprises inlayer connecting pipe, interior bellows, outer bellows and outer connecting pipe, the surface of interior bellows sets up the inlayer net cover, the surface of outer bellows sets up outer net cover, between bellows and the outer bellows including outer connecting pipe sets up, install the evacuating device interface on the end of outer connecting pipe, can be bled to the vacuum state in the outer connecting pipe.
Further, outer net cover is netted weaving layer.
Still further, the outer layer connecting pipe is a multi-layer heat insulation pipe.
Furthermore, the inner corrugated pipe and the outer corrugated pipe of the utility model are soft stainless steel pipes.
Has the advantages that: compared with the prior art, the utility model, its beneficial effect is:
1. the utility model discloses an inside and outside two-layer bellows will need be taken out into the connecting pipe protection of high vacuum state to install the evacuating device interface on the connecting pipe, make things convenient for the evacuation.
2. The utility model discloses a comparatively soft bellows has realized the hose effect, makes things convenient for on-the-spot assembly.
Drawings
Fig. 1 is a schematic structural view of the high-efficiency heat-insulation vacuum hose of the present invention.
Detailed Description
The present invention will be further described with reference to the following detailed description.
As shown in figure 1, the high-efficiency heat insulation vacuum hose is composed of a hose body and mounting flanges 8 arranged at two ends of the hose body. The hose body comprises inlayer connecting pipe 1, interior bellows 2, outer bellows 5, and outer connecting pipe 6, the surface of interior bellows 2 sets up inlayer net cover 3, the surface of outer bellows 5 sets up outer net cover 4, between bellows 2 and outer bellows 5 including outer connecting pipe 6 sets up, installation evacuating device interface 7 on the end of outer connecting pipe 6, can be bled to the vacuum state in the outer connecting pipe 6.
The outer net cover 4 is a net-shaped braided layer.
The outer layer connecting pipe 6 is a multi-layer heat insulation pipe.
The inner corrugated pipe 2 and the outer corrugated pipe 5 are both soft stainless steel pipes.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
