Abstract
The invention relates to a connection structure for an inner supporting tube and an outer supporting tube at the front end of a chemical liquid gas bottle. The connection structure comprises the inner supporting tube and the outer supporting tube, wherein the centers of the inner supporting tube and the outer supporting tube are axially overlapped; the two ends of the inner supporting tube and the outer supporting tube are respectively connected through a first ring sleeve and a second ring sleeve, and the first ring sleeve and the second ring sleeve are spirally connected with the inner supporting tube respectively; a first ring groove recesses towards the center is formed in the outer peripheral surface of the first ring sleeve, and a second ring groove axially recesses is formed in the side surface of the second ring sleeve; one end of the outer supporting tube is inserted into the second ring grove, and an end surface ring edge matched with the first ring groove is arranged at the other end of the outer supporting tube. As the inner supporting tube is spirally connected with the ring sleeves, the connection structure is easy and convenient to operate and high in stability. As the outer supporting tube is connected with the ring sleeve in a manner of buckling the ring grooves with flanges, the connection structure is easy and convenient to operate and high in mounting speed. Both the inner supporting tube and the outer supporting tube adopt a thin-wall structure and are small in section area and small in heat leakage.
Description
Technical field
The present invention relates to chemical equipment technical field, particularly relate 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.
Summary of the invention
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 technical solution adopted in the present invention 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.
Beneficial effect of the present invention is as follows:
Inner support tube of the present invention 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 invention is thin walled structures, and its sectional area is little, leaking heat is little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, inner support tube; 2, outer support pipe; 21, end face ring edge; 3, the first ring set; 31, the first annular groove; 4, the second ring set; 41, the second annular groove.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the linkage structure of support tube inside and outside the chemical liquid liquefied gas bottle front end of the present embodiment, comprise central shaft to the inner support tube 1 overlapped and outer support pipe 2, inner support tube 1 is connected respectively by the first ring set 3 and the second ring set 4 with the two ends of outer support pipe 2, first ring set 3 and the second ring set 4 are connected with inner support tube 1 spiral respectively, the outer circumferential face of the first ring set 3 is with the first annular groove 31 of heart depression wherein, the side of the second ring set 4 is with the second annular groove 41 of axial depression, one end of outer support pipe 2 is inserted in the second annular groove 41, the other end is with the end face ring edge 21 coordinated with the first annular groove 31.
Inner support tube of the present invention 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 invention is thin walled structures, and its sectional area is little, leaking heat is little.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
