Description
Technical field
The utility model relates to metal hose technical field, in particular to a kind of metal hose of inner lining structure.
Background technique
Metal hose is the important composition component in modern industrial equipment connecting pipeline, is widely used in environmental protection, petroleum, change
All conglomeraties such as work, metallurgy, shipbuilding, building materials, plastic cement, papermaking, diesel oil machinery, electronics, electric heating, domestic gas.According to knot
Structure and purposes can be divided into：Flange form, welded type, screw-type, joint type, protected against explosion, condenser special hose, heavy oil are dedicated soft
Pipe, medicinal metal hose, chemical industry metal hose, air-conditioning metal hose special, stainless steel corrugated flexible hose etc..Applied to chemical industry row
The metal hose of industry generally requires inside lining anti-corrosive material, such as liner PTFE when main conveying corrosive liquid and gas,
And it needs periodically to carry out pressure test leak-detecting.Existing PTFE inner liner metal hose, generally there is two layers or three-decker.Wherein three-decker
Internal layer is PTFE hose, and middle layer is metal bellows, and outer layer is metal net, has preferable safety, shortcoming
It is that there are still following problems in actual use for form PTFE inner liner metal hose：First is that carrying out when hermeticity experiment in PTFE
Lining hose is easy the interference by metal bellows, and the intact of lining cannot be completely secured；Second is that being carried out to internal layer PTFE hose
It needs to split out hose from pipeline when pressure test leak-detecting, it is cumbersome.
Such as Chinese patent notification number CN206234500U, denomination of invention：A kind of the PTFE hose and its composition of inner lining structure
PTFE metal hose.The utility model discloses a kind of PTFE hose of inner lining structure, including PTFE hose, and the PTFE is soft
Pipe outer wall is interrupted along its length is equipped with several groove rings, and the PTFE hose inner wall is smooth surface；In each groove ring
It is equipped with the reinforcement steel wire ring being placed on outside PTFE hose.
For another example Chinese patent notification number CN2765033Y, denomination of invention：A kind of internal and external screw thread polytetrafluoroethyl-ne -ne metal is soft
Pipe is mainly used for the industries such as tire, chemical industry, chemical fibre as insulation and trandfer fluid, gas conduit.Including intermediate tube body and both ends
Pipe fitting, its main feature is that tube body is by polytetrafluoroethyllining lining pipe, glass-weave silk middle tube and stainless steel braided wires outer tube
Three layers are closely combined；One end pipe fitting includes tube core and tube core outer tube, and other end pipe fitting includes tube core, tube core housing
Pipe and nut.
Summary of the invention
The purpose of this utility model is that in view of the deficiencies of the prior art, it is simple to provide a kind of structure, pressure test leak-detecting operation letter
The metal hose of single, accurate inner lining structure.
To solve the above problems, the utility model uses following technical scheme：A kind of metal hose of inner lining structure, including
Tube body and the connecting flange that the tube body both ends are arranged in, the tube body are closely multiple by liner hose, middle tube and outer tube
Close, be provided with the pressure test leak-detecting pipe being connected to the tubular body on the tube body, the pressure test leak-detecting pipe and it is described in
Layer seal of tube connection.
The tube body preferably includes main pipe and the connector that main pipe both ends are arranged in, and the connecting flange is connected to described
Connector on.
The pressure test leak-detecting pipe is preferably provided on the connector.
The middle tube is preferably metal bellow.
The outer tube is preferably stainless steel braided wires.
The liner hose of the utility model can select corrosion resistant material according to practical condition, as PTFE, PFA,
PP, PE, PVC etc., metal bellow middle tube can choose the materials such as carbon steel, stainless steel, aluminium.
Compared with prior art, the utility model has the following advantages that：
1, structure is simple, and pressure test leak-detecting is fast accurate, when carrying out air-tight test, can make liner by pressure test leak-detecting pipe
Hose is in communication with the outside, and effectively avoids the interference of metal bellows；
2, pressure test leak-detecting is easy to operate, can carry out pressure testing to inner-layer hose in the case where not splitting out hose from pipeline
Leak detection, significantly improves the efficiency of pressure test leak-detecting.
