Furthermore, a spring for keeping the heat preservation hose in a straight tube shape is arranged in the heat preservation hose. On the one hand, to avoid non-collapse of the media flow conduit; the most important aspect is that the whole heat preservation unit still keeps a full state even when the heat preservation hose is bent, and the heat preservation hose is prevented from being directly attached to the medium runner pipe.

Furthermore, spring pin pieces are symmetrically arranged on the left joint and the right joint, and rollers are arranged at the end heads of the spring pin pieces; the spring pin piece props the medium flowing pipeline against the clamping device through the roller. The heat preservation unit and the medium flowing pipeline can be well fixed without loosening, and the roller is convenient for the heat preservation unit to slide along the axial direction.

Preferably, the left joint is provided with an annular groove, and a magnet is fixed in the annular groove; the magnetic conduction piece on the end face of the right joint is an annular convex magnetic conduction piece which is matched with the annular groove. The annular raised magnetic conduction piece and the annular groove can ensure the coaxiality of the adjacent heat preservation units and can not fall off when being stressed in the radial direction.

Furthermore, flexible sealing layers are arranged on the end faces of the left joint and the right joint. The internal heat can not be dissipated, and the heat sealing effect is improved.

Preferably, left side joint and right side joint all be the ladder shaft tubulose, heat preservation hose and spring pin spare all set up in corresponding ladder department.

The utility model has the advantages of it is following:

(1) the arrangement of the magnet and the annular convex magnetic conduction piece in the heat preservation unit is convenient to connect;

(2) the arrangement of the spring can ensure the filling performance of the heat-insulating hose, and the heat-insulating unit is not in large-area contact with the medium flow pipeline even if the medium flow pipeline is bent, so that the heat-insulating effect is improved; due to the arrangement structure of the two components, when overhauling is carried out, the two components only need to be stressed axially, and are automatically butted after being loosened, so that the overhauling is convenient;

(3) the whole heat preservation unit can be recycled, and the cost is saved.

Detailed Description

The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.

As shown in fig. 1 to 4, in the medium flow pipeline installation structure, a heat insulation layer is arranged outside the medium flow pipeline 1, and the heat insulation layer is formed by butting a plurality of heat insulation units 3.

In the scheme, as shown in fig. 2 and 4, the heat preservation unit 3 comprises a heat preservation hose 4, two ends of the heat preservation hose 4 are respectively provided with a left joint 5 and a right joint 6, wherein the left joint 5 is provided with an annular groove 501, and a magnet 7 is fixed in the annular groove 501 through a screw; and the end surface of the right joint 6 is provided with an annular convex magnetic conducting piece 601. When the adjacent heat preservation units 3 are in butt joint, the annular convex magnetic conduction piece 601 is inserted into the annular groove 501 in a matching mode, and butt joint is achieved under the adsorption of the magnet 7. When the butt joint receives a force in the radial direction, the butt joint is not easy to fall off.

In this scheme, form annular cavity between medium flow pipeline 1 and the heat preservation unit 3, avoid heat preservation hose 4, butt joint and the contact of medium flow pipeline 1 in the heat preservation unit 3 to improve the heat preservation effect. Therefore, the left joint 5 and the right joint 6 are symmetrically provided with spring pin pieces 8, and the spring pin pieces 8 are in an elastic pin shape and are installed with the corresponding joints in a matching way through threads; at the end of the spring pin 8, a roller 801 is provided. The working principle is as follows: the spring pin member 8 clamps the medium flowing pipe 1 by the roller 801, and when the heat preservation unit 3 needs to be moved axially, the roller 801 can be moved conveniently. The effect that the insulation unit 3 can be well fixed on the medium flow pipeline 1 and cannot be easily loosened in the axial direction is also achieved.

As shown in fig. 3, in order to further prevent the insulating hose 4 from contacting the medium flow pipe 1, a spring 9 for keeping the insulating hose 4 in a straight pipe shape is provided in the insulating hose 4, and both ends of the spring 9 are welded to the inner wall of the joint. In the working process, the medium flowing pipeline 1 is prevented from being soft and flat, and the whole heat insulation unit 3 still keeps a full state when the heat insulation hose 4 is bent.

In this embodiment, a flexible sealing layer 10 is further provided at the end faces of the left joint 5 and the right joint 6. The internal heat can not be dissipated, and the heat sealing effect is improved.

In this embodiment, left side joint 5 and right side joint 6 all are the step shaft tubulose, and heat preservation hose 4 and spring round pin spare 8 all set up in the ladder department that corresponds, avoid heat preservation hose 4's installation department and spring round pin spare 8's installation department to produce the interference.
