Abstract
The utility model discloses a cold-resistant durable PVC drain pipe which comprises an inner layer pipe and an outer layer pipe. The cold-resistant durable PVC drain pipe is characterized in that an axial connecting rib plate is arranged between the inner layer pipe and the outer layer pipe, obliquely-arranged supporting plates connected with the outer side wall of the inner layer pipe and the inner side wall of the outer layer pipe are arranged on the two sides of the connecting rib plate respectively, the supporting plates and the connecting rib plate form a quincuncial structure, cold-resistant agents are filled into the clearance between the outer layer pipe and the inner layer pipe and the clearances between the supporting plates and the connecting rib plate, a flexibilizer coating is arranged outside the outer layer pipe, and a polyurethane insulation coating coats the flexibilizer coating. The cold-resistant durable PVC drain pipe is reasonable in structural design, through the dual-layer pipe structure, meanwhile, the structural design of the supporting plates and the connecting rib plate of the quincuncial structure and the flexibilizer coating is matched, the strength of the overall structure is increased, pressure-resistant properties are good, the heat preservation function is achieved through the structure of the cold-resistant agents and the polyurethane insulation coating, a pipe body can bear low temperature in winter, and the pipe is not prone to being damaged and long in service life.
Description
Technical field
The utility model relates to pipeline field, relates in particular to a kind of cold-resistant durable PVC waste pipe.
Background technique
Existing PVC drain structure is simple, mostly adopts single layer structure, in order to gain in strength, be mostly in body, to add steel wire interlayer, although increased intensity, under cryogenic conditions, steel wire and body can produce peeling, easily damage, thereby affect its working life.
Model utility content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of cold-resistant durable PVC waste pipe is provided.
The utility model is achieved through the following technical solutions:
A kind of cold-resistant durable PVC waste pipe, include inner tube and external pipe, it is characterized in that: between described inner tube and external pipe, be provided with the axial gusset that is connected, the both sides of described connection gusset are respectively equipped with the dunnage being obliquely installed being connected with inner tube outer side wall and external pipe madial wall, described dunnage be connected gusset and form * shape structure, space between described inner tube, external pipe and dunnage, connection gusset is filled with cold-resistant agent, described external pipe is provided with plasticizer coating outward, and described plasticizer coating is coated with polyurethane insulation coating outward.
The utility model has the advantages that:
The utility model reasonable in design, by the structure of bimetallic tube, the dunnage and the structural design that is connected gusset and plasticizer coating of the * shape structure between simultaneously coordinating, increased integrally-built intensity, good pressure-resistant performance, by the structure of cold-resistant machine and polyurethane insulation coating, play insulation effect, can make body can bear the lower temperature in winter, be not easy to damage long service life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
