Abstract

The utility model relates to the field of pipelines used for connecting explosion-proof equipment, in particular to an explosion-proof connecting tube. The explosion-proof connecting tube is provided with a connecting tube body and connectors at the two ends of the connecting tube body. The connecting tube body is fixedly connected with the connectors through outer sleeves. The connectors are bolt assemblies or flanges which are fixedly connected with the connecting tube body. According to the explosion-proof connecting tube, the connecting tube body and the connectors are connected through assist of the outer sleeves, the connecting portions of the connectors and the connecting tube body are prolonged, the stress borne by the connecting portions is large, the connecting tube body can be damaged easily, the outer sleeves can achieve a good protecting effect on the outer sleeves, and the service life of the connecting tube body is prolonged. The mode of the bolt assemblies or the mode of the flanges is used in the connectors, so that the service life of the explosion-proof connecting tube is greatly prolonged.

Description

A kind of explosion-proof connecting tube
Technical field
The utility model relates to the pipeline field connecting between antiknock device, relates in particular to a kind of explosion-proof connecting tube.
Background technique
Explosion-proof connecting tube has been applicable to explosive gas or mixture place, line or steel pipe wiring as permissible electrical equipment are bending, the place larger as the bending difficulty of wiring connects used, the connecting head at existing explosion-proof connecting tube two ends mostly is connecting bolt, the screw thread of connecting bolt outside repeatedly loads and unloads rear easy wearing and tearing, cause fastening strength to reduce, connecting hose and connecting head come off, and affect the normal use of equipment.Existing explosion-proof connecting tube two ends connecting head pattern is single in addition, and suitability is bad, is unsuitable for the extensive use of explosion-proof connecting tube.
Model utility content
The purpose of this utility model is to overcome the defect that prior art exists, and a kind of firm and reliable connection is provided, and join strength is high, and the good explosion-proof connecting tube of fit.
The technological scheme that realizes the utility model object is: a kind of explosion-proof connecting tube, has connecting tube body and the connecting head that is positioned at connecting tube body two ends; Described connecting tube body is fixedly linked by outer sleeve and connecting head; Described connecting head is bolt assembly or the flange being fixedly connected with connecting tube body.
Technique scheme, the connecting head at described connecting tube body two ends is bolt assembly, and the bolt assembly of described connecting tube body one end comprises female adapter and the first locking nut; The other end bolt assembly comprises male connection and the second locking nut.
Technique scheme, described female adapter inside is provided with internal thread, and male connection outside is provided with outside thread, the effective joggle of described internal thread and outside thread number >=6 button.
Technique scheme, described connecting tube body one end connecting head is bolt assembly, the other end connecting head is flange.
Technique scheme, the connecting head at described connecting tube body two ends is flange.
Technique scheme, described connecting tube length L is 700~1200mm, connecting tube body internal diameter is 13~51mm.
Technique scheme, described connecting tube length L is 1000mm, connecting tube body internal diameter is 32mm.
Adopt after technique scheme, the utlity model has following positive effect:
(1) the utility model connecting tube body is assisted and is connected by outer sleeve with connecting head, extended the length of both joints, and joint is stressed larger, connecting tube body is fragile, outer sleeve can play a good protection to it, extends the working life of connecting tube body; And connecting head adopts bolt assembly or two kinds of forms of flange, the working life that can greatly improve explosion-proof connecting tube;
(2) the utility model inipple inside or outside effective joggle number are all not less than 6 buttons, can greatly improve join strength between the two, and the fastness being connected between connecting tube and equipment is improved, and have effectively guaranteed the normal operation of equipment;
(3) the utility model connecting head can select the multiple combination of bolt assembly and flange to install according to actual needs, has expanded the application area of explosion-proof connecting tube;
(4) screw thread in the utility model connecting tube length, internal diameter and two ends connecting head can be adjusted as required, meets client's diversified demand.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the utility model structural representation;
In figure 1, connecting tube body; 2, connecting head; 21, bolt assembly; 21-1, female adapter; 21-2, the first locking nut; 21-3, male connection; 21-4, the second locking nut; 3, outer sleeve.
Embodiment
(embodiment 1)
See Fig. 1, the explosion-proof connecting tube of the utility model has connecting tube body 1 and is positioned at the connecting head 2 at connecting tube body 1 two ends; Connecting tube body 1 is fixedly linked by outer sleeve 3 and connecting head 1; Bolt assembly or the flange of connecting head 2 for being fixedly connected with connecting tube body 1.The connecting head 2 at connecting tube body 1 two ends is bolt assembly 21, and the bolt assembly 21 of connecting tube body 1 one end comprises female adapter 21-1 and the first locking nut 21-2; The other end bolt assembly 21 comprises male connection 21-3 and the second locking nut 21-4.Female adapter 21-1 inside is provided with internal thread, and male connection 21-3 outside is provided with outside thread, the effective joggle of internal thread and outside thread number >=6 button.
Preferably, connecting tube body 1 one end connecting head 2 is bolt assembly 21, and the other end connecting head 2 is flange, or the connecting head 2 at connecting tube body 1 two ends is flange.
