Abstract
The invention discloses a heating pipe sleeve, which comprises a sleeve body. An iron sheet is arranged at the bottom of the sleeve body, a closing plug formed in stretching processing mode is arranged in the middle of the iron sheet, the closing plug is in close fit connection with the sleeve body, and the edge of the iron sheet is welded with the sleeve body. The iron sheet at the closing end at the bottom of the heating pipe sleeve is forms the closing plug with certain strength after stretching, the closing plug is in close fit with the pipe wall of the sleeve, automatic location can be conducted without spot welding, the heating pipe sleeve can be directly welded, the welding gap position is at the top end of the sleeve, no effect is caused on the diameter of the sleeve, and simultaneously welding gap firmness is increased.
Description
Technical field
The present invention relates to the generator of absorption and diffusion type refrigerating box, particularly a kind of heating pipe sleeve pipe of the generator for the absorption and diffusion type refrigerating box.
Background technique
As everyone knows, the generator of absorption and diffusion type refrigerating box comprises inner tube, outer tube and heating pipe sleeve pipe, and heating pipe sleeve pipe and inner tube are affixed, in the heating pipe sleeve pipe, place heater to inner tube in heating liquid, generator can be worked.
Usually the closed end of heating pipe sleeve pipe is to weld a circular small iron plate in the weldless tube cannula tip of 12*1.2, after this small iron plate must be fixed by some heel pipe, just can carry out welding processing, otherwise can't fix, inefficiency and be difficult for centering, be easy to be partially welded, weld joint postwelding on outer diameter side has increased pipe diameter, affects the assembling of heating pipe sleeve pipe and generator outer tube.
Summary of the invention
The present invention has overcome above-mentioned the deficiencies in the prior art, and a kind of assembling that is easy to is provided, and has improved working efficiency, has increased the heating pipe sleeve pipe of weld seam fastness.
Technological scheme of the present invention is achieved in that
A kind of heating pipe sleeve pipe, comprise sleeve body, in the bottom of sleeve body, be provided with iron plate, described iron plate middle part is provided with the closing cock that drawn is processed to form, described closing cock is connected with sleeve body tube wall close-fitting, and edge and the sleeve body of iron plate weld together.
Originally the opening end at heating pipe sleeve pipe top is not through processing, the matching gap of heating pipe sleeve pipe and generator outer tube is excessive should not weld, and when welding welding wire filled out many can dwindle the mouth of pipe, make heater can't insert installation, needing round file file to go after unnecessary metal could normal mounting, greatly reduces efficiency.As preferably, the top of sleeve body is the enlarging formed through punching press.Can make like this heating pipe ferrule openings place and generator outer tube closely cooperate conveniently welds; And, even have excess metal to stay in the mouth of pipe during welding, the insertion that also can not affect heater is installed.Sleeve pipe is easier centralized positioning also, has guaranteed that the gap of heating pipe sleeve pipe surrounding is that liquid is full of surrounding, thereby heating promotes inner tube uniformly, and the protection heat does not run off.
Adopted the invention has the beneficial effects as follows of technique scheme:
Be formed with the closing cock of some strength after the iron plate of heating pipe sleeve bottom closed end of the present invention is stretched, closing cock and sleeve pipe tube wall close-fitting, do not need spot welding just can locate voluntarily, directly can weld and weld joint on the top of sleeve pipe on the not impact of diameter of sleeve pipe, increased the fastness of weld seam simultaneously.
The accompanying drawing explanation
The linkage structure schematic diagram that Fig. 1 is heating pipe sleeve pipe of the present invention and iron plate;
The structural representation that Fig. 2 is iron plate;
The structural representation that Fig. 3 is the heating pipe sleeve pipe.
Embodiment
The specific embodiment of the present invention is as follows:
Embodiment: a kind of heating pipe sleeve pipe, as shown in Figure 1, comprise sleeve body 1, be provided with iron plate 2 in the bottom of sleeve body 1, as shown in Figure 2, described iron plate 2 middle parts are provided with the closing cock 3 that drawn is processed to form, and described closing cock 3 is connected with sleeve body 1 tube wall close-fitting, and the edge of iron plate 2 and sleeve body 1 weld together.As shown in Figure 3, the top of sleeve body 1 is the enlarging 4 formed through punching press.
