Abstract
The utility model relates to a heat preservation type corrugated flexible metal pipe which comprises a corrugated pipe body, connectors at the two ends of the corrugated pipe body, and a net cover connected to the outside of the corrugated pipe body in a sleeved mode. The connectors are spherical connectors and are connected with the corrugated pipe body through a connecting pipe. A clamping part is arranged at the end, close to the corrugated pipe body, of the connecting pipe. The net cover is fixedly connected with the connecting pipe and the clamping part through a protective cover. The two ends of the corrugated pipe body are pre-pressed and contracted to form a corrugated pre-pressed area. The net cover is covered with a thermal insulating layer which is made of polyamine foam. The outer surface of the thermal insulating layer is connected with the protecting net cover in a sleeved mode. Springs are arranged at the two ends of the protecting net cover. The heat preservation type corrugated flexible metal pipe is provided with the corrugated pre-pressed area, the thermal insulating layer, the protecting net cover, the springs and the protective cover so that the heat preservation type corrugated flexible metal pipe can have good stretch resistance, low temperature resistance and overbending resistance properties; the pipe body can still maintain good combination properties even in a reciprocating motion environment or a low temperature environment or a bending environment.
Description
technical field:
The utility model relates to a kind of corrugated metal pipeline, and especially a kind of low temperature detour moves a kind of heat insulation type corrugated flexible metal tube of use.
background technique:
Corrugated flexible metal tube is connector element important in engineering, in corrugated flexible metal tube main body, by bellows, net and joint three parts, formed, bellows is the body of metallic hose, play a part flexible, net plays a part to strengthen, shielding, joint plays a part connection, metallic hose have good ductility, corrosion resistance, high temperature resistant,, low temperature resistant, wear-resistant, pull resistance.But in actual installation and using process, the soft mistake of more existing universal metals exists some problems, in complicated pipe-line system, due to the restriction of spatial position, joint is easily by overbending, and welded joint is under the effect of tensile stress, its weld seam producing under installation or use state is easily by drawing crack, net outside bellows is also easily pullled and is come off, and under low temperature environment, also needs the specific metallic hose of production and application.
summary of the invention:
The technical problem that the utility model solves is to provide a kind of have stretch-proof, anti-overbending, cryophylactic a kind of heat insulation type corrugated flexible metal tube.
The technical scheme in the invention for solving the technical problem is: a kind of heat insulation type corrugated flexible metal tube, comprise the joint at bellows, bellows two ends and the net of the outer socket of bellows, described joint is spherical joint, between joint and bellows, by taking over, be connected, adapter is provided with holding section in the one end near bellows, described net is fixedly connected with and is taken over and holding section by sheath, and the precompressed of described bellows two ends is tightened and formed ripple precompressed zone; Described net is coated with thermal insulation layer outward, and thermal insulation layer is polyurethane foam, thermal insulation layer outer surface socket protection net, and the two ends of protection net are provided with spring.
Further, the pitch of waves of the ripple in described ripple precompressed zone is half of other positions of bellows.
Further, described net and protection net are establishment net.
The beneficial effects of the utility model are: a kind of heat insulation type corrugated flexible metal tube that the utility model relates to, in the precompressed of bellows two ends, tighten and form ripple precompressed zone, the pitch of waves of the ripple in described ripple precompressed zone is half of other positions of bellows, precompressed to bellows, increased the tensile elongation of bellows, mobile its length of using is also enough, has increased the stretch-proof of metallic hose; The spring of the two ends socket of protection net, because spring has certain rigidity, can suppress the bending at metal hose joint position, has increased the anti-overbending of joint; Net is coated with thermal insulation layer outward, can make metallic hose still use under low temperature environment normal, can resist low temperature; Thermal insulation layer outer surface socket protection net, can protect thermal insulation layer on the one hand, has increased on the other hand the de-property of whole tension of this equipment.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, bellows 11, take over 12, holding section 13, ripple precompressed zone 2, joint 3, net 31, sheath 4, thermal insulation layer 5, protection net 6, spring.
embodiment:
A kind of heat insulation type corrugated flexible metal tube as shown in Figure 1, comprise the joint 2 at bellows 1, bellows 1 two ends and the net 3 of bellows 1 outer socket, described joint 2 is spherical joint, between joint 2 and bellows 1, by taking over 11, be connected, described adapter 11 is provided with holding section 12 in the one end near bellows 1, described net 3 is fixedly connected with adapter 11 and holding section 12 by sheath 31, described bellows 1 two ends precompressed is tightened and is formed ripple precompressed zone 13, and the pitch of waves of the ripple in described ripple precompressed zone 13 is half of bellows 1 other positions; Described net 3 is outer is coated with thermal insulation layer 4, and described thermal insulation layer 4 is polyurethane foam, described thermal insulation layer 4 outer surface socket protection nets 5, and the two ends of described protection net 5 are provided with spring 6.Described net 3 and protection net 5 are establishment net.
A kind of heat insulation type corrugated flexible metal tube that the utility model relates to, in bellows 1 two ends precompressed, tighten and form ripple precompressed zone 13, the pitch of waves of the ripple in described ripple precompressed zone 13 is half of other positions of bellows, precompressed to bellows 1, increased the tensile elongation of bellows 1, mobile its length of using is also enough, has increased the stretch-proof of metallic hose; Net 3 is outer is coated with thermal insulation layer 4, can make metallic hose still use under low temperature environment normal, can resist low temperature; Thermal insulation layer 4 outer surface socket protection nets 5, can protect 4 to thermal insulation layer on the one hand, have increased on the other hand the de-property of whole tension of this equipment; The spring 6 of the two ends socket of protection net 5, because spring 6 has certain rigidity, can suppress the bending at metal hose joint position, has increased the anti-overbending of metal hose joint.
It is emphasized that, it is more than preferred embodiments of the present utility model, not model utility is done to any type of restriction in appearance, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
