Abstract
The invention relates to a connecting pipe, in particular to an anti-aging anti-explosion connecting pipe. The anti-aging anti-explosion connecting pipe comprises a connecting pipe body and a connecting device, wherein the connecting device is positioned at two ends of the connecting pipe body and is fixedly connected with the connecting pipe body, and the connecting pipe body is of a double-layer structure, and comprises an inner layer metal hose and an outer layer metal protection sleeve. The anti-aging anti-explosion connecting pipe has the advantages that the connecting pipe body adopts the double-layer structure, the internal metal hose has good bending performance, the arrangement of complicated circuits is convenient, the protection sleeve arranged at the outer part has a good protection effect on the metal hose and is made of metal materials, and the characteristics of good anti-aging performance and burning-resistant performance are realized, so the service life of the connecting pipe is greatly prolonged, and replacing resource waste and replacement trouble are avoided.
Description
Technical field
The present invention relates to a kind of connecting tube, particularly relate to a kind of anti-aging explosion-proof flexible connection pipe.
Background technique
Explosion-proof flexible connection pipe has been applicable to explosive gas or mixture place, as the line of permissible electrical equipment or steel pipe wiring bending, the place larger as the bending difficulty of wiring connects used.Existing flexible pipe outer protection cover mostly is rubber material and makes, and under rubber hose low temperature, tortuosity is little, and easily aging, and working life is low, and easy firing, threaten the safe handling of equipment, also can cause casualties time serious and tremendous economic loss.
Existing explosion-proof connecting tube two ends mostly are flexible pipe and are directly connected with the connecting bolt at two ends in addition, and when pressure is large or service time is longer, flexible pipe easily comes off from connecting bolt, affects the normal use of equipment.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, provide a kind of anti-aging, do not burn, the explosion-proof connecting tube of long service life.
The technological scheme realizing the object of the invention is: a kind of anti-aging explosion-proof connecting tube, has connecting tube body and be positioned at connecting tube body two ends and the connection set be fixedly connected with it; Described connecting tube body is double layer construction, comprises the metallic hose of internal layer and outer field metal protective sleeve pipe.
Technique scheme, described protective casing is Stainless Steel Wire woven tube.
Technique scheme, described connection set comprises inipple and is positioned at the attaching nut inside inipple.
Technique scheme, the inipple of described connecting tube body one end is provided with internal thread, and the other end inipple is provided with outside thread.
Technique scheme, described internal thread and effective joggle number >=6 of outside thread.
Technique scheme, described connecting tube body and connection set joint are also provided with gland pipe.
Technique scheme, described connecting tube length L is 700 ~ 1200mm.
Technique scheme, described connecting head outer surface is provided with zinc coat.
After adopting technique scheme, the present invention has following positive effect:
(1) connecting tube body of the present invention adopts double layer construction, inner metallic hose has good bending properties, the layout of complicated circuit can be facilitated, the protective casing that outside is provided with has good protective action to metallic hose, and adopt metal material to make, have good anti-aging, anti-burning characteristic, thus substantially increase the working life of connecting tube, avoid the waste of replacement resource and the trouble of replacing;
(2) protective casing of the present invention adopts Stainless Steel Wire braiding to form, and not only has higher amount of deflection, also has corrosion resistant advantage, thus make the present invention can apply various working environment, expand application area;
(3) the effective joggle number of inipple screw thread of the present invention is all not less than 6 buttons, greatly can improve the join strength between other equipment, effectively ensure that equipment long-term stability is run;
(4) connecting tube body of the present invention and connection set joint have additional clamping sleeve, can increase substantially the reliability that both connect, thus improve the working life of circuit in connecting tube;
(5) zinc coat that connection set outside of the present invention is provided with can improve the corrosion resistance on connection set surface, thus makes it be applicable to various working environment.
