Description
Technical field
The utility model relates to chemical equipment technical field, particularly relates to the supporting structure of liquified petroleum gas cylinder.
Background technique
Liquified petroleum gas cylinder is made up of inner bag and shell, and inner bag is connected by supporting structure with the front end of shell, forms vacuum structure between inner bag and shell.Supporting structure comprises inside and outside support tube, and the sectional area of existing support tube is comparatively large, and because leaking heat is directly proportional to sectional area, its heat conduction amount is comparatively large, affects the heat insulation effect of liquified petroleum gas cylinder, causes the air pressure in bottle to rise very fast, there is potential safety hazard.Attended operation between existing inside and outside support tube is loaded down with trivial details, after the end of two support tubes is connected by support ring, also needs to increase stiffening plate, its complex operation, assembling inconvenience; Stiffening plate increases Lou hot side and amasss, and is unfavorable for that liquified petroleum gas cylinder is incubated.
Model utility content
The above-mentioned shortcoming that the applicant exists for prior art, carries out studying and designing, and provides the linkage structure of support tube inside and outside a kind of chemical liquid liquefied gas bottle front end, and it has, and leaking heat is little, stable connection, feature simple to operate.
The technological scheme that the utility model adopts is as follows:
The linkage structure of support tube inside and outside a kind of chemical liquid liquefied gas bottle front end, comprise central shaft to the inner support tube overlapped and outer support pipe, inner support tube is connected respectively by the first ring set and the second ring set with the two ends of outer support pipe, first ring set and the second ring set are connected with inner support tube spiral respectively, the outer circumferential face of the first ring set is with the first annular groove of heart depression wherein, the side of the second ring set is with the second annular groove of axial depression, one end of outer support pipe is inserted in the second annular groove, and the other end is with the end face ring edge with first ring slot fit.
The beneficial effects of the utility model are as follows:
Inner support tube of the present utility model is connected by spiral with between ring set, and it is easy and simple to handle, steadiness is high; Outer support pipe is connected with the clamping form of flange with adopting annular groove between ring set, and it is simple to operate, installation rate is fast; Inside and outside support tube of the present utility model is thin walled structures, and its sectional area is little, leaking heat is little.
Accompanying drawing explanation
