Abstract

The invention relates to the field of lines for connecting anti-explosion equipment, in particular to an anti-explosion connecting tube, which is provided with a connecting tube body and connectors located at both ends of the connecting tube body; the connecting tube body is fixedly connected with the connectors through external sleeves; the connectors are bolt assemblies or flanges which are fixedly connected with the connecting tube body. Since the external sleeves help to connect the connecting tube body with the connectors, the joints between the connecting tube body and the connector are lengthened; moreover, since the stress on the joints is great, the connecting tube body can be easily damaged, the external sleeves can play the role of protecting the connecting tube body well, and thereby the service life of the connecting tube body is prolonged; since the two forms, i.e. the bolt assemblies or the flanges, are adopted by the connectors, the service life of the anti-explosion connecting tube can be prolonged greatly.

Description

Explosion-proof connecting tube
Technical field
The present invention relates to the pipeline field connected between antiknock device, particularly relate to a kind of explosion-proof connecting tube.
Background technique
Explosion-proof connecting tube 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, 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.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, provide a kind of firm and reliable connection, join strength is high, and the explosion-proof connecting tube that fit is good.
The technological scheme realizing the object of the invention is: a kind of explosion-proof connecting tube, has connecting tube body and the connecting head being positioned at connecting tube body two ends; Described connecting tube body is fixedly linked by outer sleeve and connecting head; Described connecting head is the bolt assembly or flange that are 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, described internal thread and outside thread effective joggle number >=6 button.
Technique scheme, described connecting tube body one end connecting head is bolt assembly, and 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, and connecting tube body internal diameter is 13 ~ 51mm.
Technique scheme, described connecting tube length L is 1000mm, and connecting tube body internal diameter is 32mm.
After adopting technique scheme, the present invention has following positive effect:
(1) connecting tube body of the present invention is connected by outer sleeve is auxiliary with connecting head, extend the length of both joints, and joint is stressed comparatively large, 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 flange two kinds of forms, greatly can improve the working life of explosion-proof connecting tube;
(2) inipple inside of the present invention or outside effective joggle number are all not less than 6 buttons, greatly can improve join strength between the two, the fastness be connected is improved, effectively ensure that the normal operation of equipment between connecting tube with equipment;
(3) connecting head of the present invention can select the multiple combination of bolt assembly and flange to install according to actual needs, expands the application area of explosion-proof connecting tube;
(4) screw thread in connecting tube length of the present invention, internal diameter and two ends connecting head can adjust as required, meets the diversified demand of client.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is structural representation of the present invention;
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 present invention 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; Connecting head 2 is the bolt assembly or flange that are 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, internal thread and outside thread effective joggle 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.
Preferably, connecting tube length L can be designed to 700 ~ 1200mm according to client's actual demand, and connecting tube body 1 internal diameter is designed to 13 ~ 51mm, for the connection between distinct device, thus more reasonably utilizes resource, avoids material and energy waste.The present embodiment connecting tube length L is 1000mm, and connecting tube body 1 internal diameter is 32mm.
