Abstract
The invention discloses a thermal-insulation explosion-proof metal hose which is a double-end straight pipe consisting of pipe joints, an inner pipe, an inner corrugated pipe, an inner mesh sleeve, an outer corrugated pipe and an outer mesh sleeve. The inner corrugated pipe is sleeved in the inner mesh sleeve, and two end surfaces flushed are respectively connected to the pipe joints; the outer corrugated pipe is sleeved in the outer net mesh, and two ends flushed are respectively connected with main-diameter ends of sleeves to form an outer pipe; the inner diameter of the outer pipe is larger than the outer diameter of the inner pipe, and the inner pipe is sleeved into the outer pipe coaxially, so that the explosion-proof structure is formed. The sleeves at two ends of the outer pipe are connected with outer walls of necks of the pipe joints. Radial adapters are arranged on the walls of the sleeves, and are communicated with a cavity between the outer pipe and the inner pipe. The inner pipe and the outer pipe are sleeved to form the explosion-proof structure and to achieve the thermal insulation effect. The structure is adaptable to explosion-proof metal hoses in various specifications.
Description
Technical field
The present invention relates to a kind of metallic hose, specifically, the present invention relates to a kind of explosion-proof metallic hose of providing insulating structure for oneself.
Background technique
Metallic hose is indispensable constituent element in the industrial pipe network, is mainly used in the connection of branch equipment.Metallic hose by the technical specification design is the mono-layer tube structure, has good flexibility and enough intensity, can satisfy the transmission of conventional media under normal temperature condition fully.But when the metallic hose transmission medium viscosity of prior art is bigger, and environment is when low, full-bodied medium retrogradation, and mobile variation, even medium is deposited in the ripple of metallic hose and forms caking.The caking screens makes metallic hose lose due flexibility, reduces flow area, and this kind blocks problem must increase interior pressure, superpressure easily causes metallic hose to damage, for some inflammable and explosive places, metallic hose damages and brings potential safety hazard is not general considerations, should carry out necessary technology and improve.
Summary of the invention
The present invention is primarily aimed at the deficiencies in the prior art, and it is simple to propose a kind of insulating structure, guarantees that pipe is interior unimpeded, the explosion-proof metallic hose of safe thermal insulating type.
The present invention is achieved through the following technical solutions technical goal.
The explosion-proof metallic hose of thermal insulating type, it constitutes the double end straight-through tube by pipe joint, sleeve pipe, inner corrugated pipe, interior net, outward corrugated tube and outer net.Described inner corrugated pipe cover is incorporated among the Intranet cover, and the both ends of the surface that flush connect into the interior pipe with strengthened layer with flange edge pipe seal outwardly respectively.Described outward corrugated tube cover is incorporated among the outer net cover, and the two ends that flush are tightly connected into the outer tube with strengthened layer with sleeve pipe major diameter nose end respectively.Its improvements are: outer tube diameter is thicker than interior external diameter of pipe, and the coaxial cover of interior pipe is incorporated into and constitutes blasting resistance structure in the outer tube, and the sleeve pipe that is positioned at the outer tube two ends is tightly connected with supporting pipe joint neck outer wall respectively.The tube wall of described sleeve pipe is provided with radially and takes over, and takes over the cavity of linking up between outer tube and the interior pipe.
As further improvement project, the outward corrugated tube in the outer tube is bigger by 20%～30% than the inner corrugated pipe bore in the interior pipe.
The present invention compared with prior art has following good effect:
1, the inner and outer pipe shrink-fit structure is simple, making is easy;
2, the outer tube sleeve with strengthened layer is combined on the outer wall of inner tube, except constituting blasting resistance structure, also plays insulation effect, the cavity that forms between two pipes is introduced heat medium through taking over, can improve the ambient temperature of metallic hose, can avoid winter medium in bellows, to lump, directly improve transmission quality.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
The explosion-proof metallic hose of thermal insulating type shown in Figure 1, it constitutes the double end straight-through tube by pipe joint 1, sleeve pipe 2, inner corrugated pipe 3, interior net 4, outward corrugated tube 5 and outer net 6.Described inner corrugated pipe 3 covers are incorporated among the Intranet cover 4, and both are isometric, and the both ends of the surface that flush are tightly connected into interior pipe with flange edge pipe joint 1 outwardly respectively.Flexible interior net 4 is enclosed within on inner corrugated pipe 3 outer walls and constitutes strengthening structure, can either significantly improve inner corrugated pipe 3 bearing capacities, does not reduce the flexibility of inner corrugated pipe 3 again.Described outward corrugated tube 5 covers are incorporated among the outer net cover 6, and both are isometric, the two ends that flush respectively with the sleeve pipe 2 major diameter nose ends formation outer tube that is tightly connected.Flexible outer net 6 is enclosed within on outward corrugated tube 5 outer walls and constitutes strengthening structure.This middle external tube internal diameter is thicker than interior external diameter of pipe, and the coaxial cover of interior pipe is incorporated in the outer tube, and the sleeve pipe 2 that is positioned at the outer tube two ends is tightly connected with supporting pipe joint 1 neck outer wall respectively.Because there is difference in size in the inner and outer pipe diameter, forms cavity between two pipes.Outward corrugated tube 5 bores are Φ 172mm in the present embodiment, inner corrugated pipe 3 bore Φ 120mm, and two pipe diameter differences reach 30%.The tube wall of described sleeve pipe 2 is provided with radially takes over 2.1, take over 2.1 cavitys of linking up between outer tube and the interior pipe, introduce heat medium through taking over 2.1, can improve the ambient temperature of metallic hose, can avoid winter medium in inner corrugated pipe 3, to lump, be conducive to improve the transmission quality of metallic hose.In addition, outer tube sleeve is combined in and also plays explosion-proof on the outer wall of inner tube, significantly improves the safety in utilization of metallic hose.
