Be equipped with the burr between the adjacent corrugate arch. The surface of outer body is equipped with first fire -retardant layer, and the internal surface of interior body is equipped with the fire -retardant layer of second. The utility model discloses a bellows is multilayer structure to be equipped with the heat preservation, outer pipe inner wall is equipped with the cavity, and consequently, it is thermal -insulated respond well to keep warm, is difficult for the frost crack winter, is favorable to increase of service life. The bellied cross sectional shape of corrugate adopts trapezoidal design for the bellows has sensitiveer deformation rate, and the reinforcing bellows is to the adaptability of surrounding environment. It can effectively improve the fire behavior of this bellows to set up fire -retardant layer.
Description
Technical field
This utility model belongs to pipe technology field, particularly relates to a kind of corrugated tube.
Background technology
Corrugated tube is the tubing of the wave sample of a kind of external form rule, be mainly used in needing the least bending radius, irregular turn, pipeline will produce flexible part or is not easy to do the connection of pipeline and pipeline by the occasion that fixing elbow is installed, corrugated tube is flexible, elongate or compress.
The shortcoming that the corrugated tube of prior art is primarily present is: heat insulating effect is the best；Corrugated tube is when deforming upon, and corrugated tube telescopicing performance is poor, and corrugated tube can be made to damage when there is significantly deformation, reduces the service life of corrugated tube.
Therefore, how to solve above-mentioned technical problem and become the direction that this skilled person makes great efforts.
Utility model content
The purpose of this utility model is just to provide a kind of New corrugated pipe, in place of being fully solved above-mentioned the deficiencies in the prior art.
The purpose of this utility model is realized by following technical proposals:
A kind of New corrugated pipe, it is characterized in that: include outer tube body and interior tube body, it is protruding that described outer tube body surface has corrugated, interior tube body is straight tube pipe, interior tube body outer wall fits tightly and is fixed on outer tube body inwall, and outer tube body inwall correspondence corrugated projection is provided with cavity, the cross sectional shape of described corrugated projection is trapezoidal.
As preferably, between described adjacent corrugations shape projection, it is provided with burr.
As preferably, described outer tube body two ends are smooth interface, are socketed cutting ferrule at smooth seam, and the pipe protection sheath of outer surface of tube body socket outside, the end sleeve of pipe protection sheath is connected in cutting ferrule, and the other end of cutting ferrule is connected to smooth interface tail end.
As preferably, described pipe protection sheath uses transparent plastic material to make.
As preferably, described smooth interface is provided with the seal groove for assembling sealing ring.
As preferably, between described outer tube body and interior tube body, it is provided with heat-insulation layer.
As preferably, the surface of described outer tube body is provided with the first flame-retardant layer, and the inner surface of interior tube body is provided with the second flame-retardant layer.
Compared with prior art, the beneficial effects of the utility model are:
1. this corrugated tube is multiple structure, and is provided with heat-insulation layer, and outer tube body inwall is provided with cavity, and therefore, heat insulating effect is good, and winter is difficult to bursting by freezing, is conducive to increasing the service life.2. the cross sectional shape that corrugated is protruding uses trapezoidal design, when corrugated tube deforms upon, owing to trapezoidal rate of deformation is more than semicircular rate of deformation in prior art, the active force that deformation is produced is rapidly absorbed, avoid deforming force and persist to cause on corrugated tube aging, improve the service life of corrugated tube；The use of trapezium structure simultaneously makes corrugated tube have sensitiveer rate of deformation, corrugated tube occur stretch rapidly time can effectively Absorption power to protect corrugated tube, enhancing the corrugated tube adaptability to surrounding.3. burr is set between adjacent corrugated projection so that corrugated tube can bear deformation greatly and be unlikely to damage, and adds the bending property of corrugated tube simultaneously, can better adapt to surrounding.4. pipe protection sheath is set, it is possible to effectively protect bellows body, it is to avoid leak air using corrugated tube conveying natural gas when phenomenon.5. flame-retardant layer is set and can be effectively improved the fire protecting performance of this corrugated tube.
