Abstract
The utility model relates to an air delivery pipe for cold air filling, which comprises a plastic inner pipe (1), a polyethylene chemically cross-linked high foamed belt (PEF) which is winded around the plastic inner pipe (1), adhesive agent (2) which is glued on the polyethylene chemically cross-linked high foamed belt (PEF), glass cloth (3) whose outermost layer is wound with polyurethane adhesive and joints with conicity, which are bonded at the two ends of the air delivery pipe for cold air filling. The air delivery pipe for cold air filling has good heat-insulation property and easy fabrication. When the construction is carried out, as long as the pipe joints of two pieces of the air delivery pipes for cold air filling are matched and inserted, the air delivery pipe for cold air filling can be used. The inner diameter of the pipe joints is as big as the inner diameter of the air delivery pipe for cold air filling, which is favorable to the pass of the air.
Description
The utility model belongs to pneumatic tube, particularly fills colod-application pneumatic tube.
Existing pneumatic tube has rubber pipe, metal tube etc., but is not exclusively used in the pneumatic tube of carrying cold air, if be used to send cold air with rubber pipe, metal tube, it constructs inconvenient, and the cost height, therefore, is necessary to provide a kind of colod-application pneumatic tube that fills.
The purpose of this utility model provides a kind of colod-application pneumatic tube that fills, this pneumatic tube good heat insulating, and processing and fabricating connects easy construction easily easily.
For achieving the above object, the utility model is by the following technical solutions: it comprises plastic inner pipe, is entangled in the plastic tube high foaming band of outer polyethylene chemical crosslinking (PEF), is with to be stained with binder, outermost surface is tied with the glass cloth of addition polymerization ammonia ester gum, and the pipe two ends are stained with the joint of band tapering.
Above-mentioned plastic tube is low temperature resistant polyethylene pipe, and other low temperature resistant plastic tube is also passable.Gas temperature pact-40C in the pneumatic tube.Joint adopts engineering plastics such as ABS to make.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1: the sectional view of pneumatic tube
The A-A sectional view of Fig. 2: Fig. 1
Fig. 1, among Fig. 2, (1) is plastic inner pipe, and material is low temperature resistant polyethylene from high pressure process, plastic tube twines the high foaming band of the polyethylene chemical crosslinking that is stained with the polyethylene glue stick (PEF) (2) outward, (3) for being added with the glass cloth of polyurethane adhesive, (4) are pipe joint, and the tapering of managing two end connectors is 50:1, during use, the pipe joint of two pipes is got final product inserting, and promptly the enlarged of pipe matches easy construction with the part of dwindling of another root pipe.
The utility model has the advantages that: the good heat insulating of appendix, to make easily, site operation is convenient, and after two pipes connected, ips remained unchanged, and is conducive to the gas flow mistake.
Claims (2)
1, a kind ofly fills colod-application pneumatic tube, it is characterized in that it comprises: plastic inner pipe (1), be entangled in the plastic tube high foaming band of outer polyethylene chemical crosslinking (PEF), be with to be stained with binder (2), outermost surface is tied with the glass cloth (3) of addition polymerization ammonia ester gum, is bonded in the band tapering joint at pipe two ends.
2, fill colod-application pneumatic tube by claim 1 is described, the tapering that it is characterized in that described pipe two end connectors is 50:1.
