Abstract
The utility model relates to a heat-insulating flexible pipe, which is composed of a flexible pipe body and at least one pipe connector, wherein a net sleeve is wrapped on the external circumference of the flexible pipe body, any pipe connector is composed of a pipe core and a holding ring, wherein the pipe core is inserted in one end of the flexible pipe body, the holding ring is sleeved on the external circumference of the net sleeve, the outer end of the holding ring is fixedly connected with the outer end of the pipe core, an insulating layer is wrapped on the external circumference of the net sleeve, the end surface of the insulating layer is adjacent to the inner end surface of the holding ring, a secondary holding ring is sleeved on the external circumference of the holding ring, the secondary holding ring wraps and covers an adjacent part between the insulating layer and the holding layer and is extended to the external circumference of the end portion of the insulating layer. The holding ring and the secondary holing ring are connected through a screw thread. The heat-insulating flexible pipe wraps the insulating layer outside the flexible pipe body, which can insulate heat and prevent heat loss, the mechanical strength of the flexible pipe body is intensified, the secondary holding ring is arranged outside the holding ring and the insulating ring on a joint to restrain the moving range of the flexible pipe body in the joint with the holding ring and the pipe core, and the mechanical strength of the joint part is improved.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to pipe element, particularly carries the flexible steel in flat section tubing of thermodynamic medium, and concrete is a kind of heat-preserving hose.
Background technique:
Extensively adopt the bellows of metal or nonmetal thin-wall pipe shaping to carry thermodynamic medium in the prior art, the braiding net is set, on the excircle of bellows with the purpose that reaches protection, strengthens.Also adopt the straight tube of flexible nonmetal material in the prior art, the braiding net is set on the excircle.This two classes flexible pipe need be provided with at joint area and to detain ring in use, detains the outside that ring is arranged on flexible pipe, detains ring and is rigid body, therefore, detains the connection part strength weak of ring and flexible pipe, occurs the damaged early stage damage that causes hose assembly easily; Simultaneously, thermodynamic medium is in traditional flexible pipe course of conveying, and insulation, heat-shielding performance is bad, causes heat loss.
Summary of the invention:
The purpose of this utility model provides a kind of heat-preserving hose, and described this heat-preserving hose will solve to be carried the flexible pipe of thermodynamic medium and detain ring connection part weak strength, insulation, the bad technical problem of heat-shielding performance in the prior art.
This heat-preserving hose of the present utility model is made of hose body and at least one pipe joint, be surrounded by net on the excircle of described hose body, any one described pipe joint is by tube core and detain the ring formation, described tube core inserts an end of hose body, the excircle of tube core is provided with ring-shaped step, described ring-shaped step is positioned at the end of hose body tube wall, the described ring set of detaining is located on the excircle of net, detaining the outer end of ring and the outer end of tube core is fastenedly connected, wherein, be coated with a thermal-protective coating on the excircle of described net, the end face of described thermal-protective coating is adjacent with the interior edge face of detaining ring, detain and be arranged with a secondary on the excircle of ring and detain ring, described secondary is detained ring and is surrounded and cover thermal-protective coating and detain the adjoiner of ring and extend to the end excircle of thermal-protective coating.
Further, be provided with the micropore of a plurality of sealings in the described thermal-protective coating.Concrete, thermal-protective coating is made of expanded ptfe or expanded ptfe material.
Further, the thickness of described thermal-protective coating is between 2mm～10mm.
Further, the described ring of detaining is detained ring by being threaded with secondary, perhaps connects by over-surplus fit structure.
Working principle of the present utility model is: the thermal-protective coating that coats outside hose body can be heat insulation, and increase the mechanical strength of hose body.Secondary detain ring limited hose body with the joint of detaining ring, tube core in range of movement, thereby increased the mechanical strength of joint area weak link.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model coats thermal-protective coating outside hose body, can be heat insulation, prevent heat loss, and increase the mechanical strength of hose body, outside ring and the thermal-protective coating secondary is set detaining of joint and detains ring, limited hose body with the joint of detaining ring, tube core in range of movement, thereby increased the mechanical strength of joint area weak link.
Description of drawings:
Fig. 1 is the axial sectional structure schematic representation of heat-preserving hose of the present utility model.
Embodiment:
As shown in Figure 1, heat-preserving hose of the present utility model is made of hose body 1 and at least one pipe joint, be surrounded by net 2 on the excircle of described hose body 1, any one described pipe joint is by tube core 3 and detain ring 4 formations, described tube core 3 inserts an end of hose body 1, the excircle of tube core 3 is provided with ring-shaped step, described ring-shaped step is positioned at the end of hose body 1 tube wall, the described ring 4 of detaining is set on the excircle of net 2, detaining the outer end of ring 4 and the outer end of tube core 3 is fastenedly connected, wherein, be coated with a thermal-protective coating 5 on the excircle of described net 2, the end face of described thermal-protective coating 5 is adjacent with the interior edge face of detaining ring 4, detain and be arranged with a secondary on ring 4 the excircle and detain ring 6, described secondary is detained ring 6 and is surrounded the end excircle that covers thermal-protective coatings 5 and the adjoiner of detaining ring 4 and extend to thermal-protective coating 5.
Further, be provided with the micropore (not shown) of a plurality of sealings in the described thermal-protective coating 5.Concrete, thermal-protective coating 5 is made of expanded ptfe or expanded ptfe material.
Further, the thickness of described thermal-protective coating 5 is between 2mm～10mm.
Further, the described ring 4 of detaining is detained ring 6 by being threaded with secondary, perhaps connects by over-surplus fit structure.
Working procedure of the present utility model is: the thermal-protective coating 5 that coats outside hose body 1 can be heat insulation, and increase the mechanical strength of hose body 1.Secondary detain ring 6 limited hose body 1 with the joint of detaining ring 4, tube core 3 in range of movement, thereby increased the mechanical strength of joint area weak link.
