Abstract
The utility model discloses a heating pipe casing pipe. The heating pipe casing pipe comprises a casing pipe body. An iron sheet is disposed at the bottom of the casing pipe body, and a closing plug formed through a stretching process is disposed in the middle of the iron sheet and is connected with a pipe wall of the casing pipe body in a close-fitting mode. Edges of the iron sheet are welded together with the casing pipe body. The iron sheet arranged on a closing end at the bottom of the casing pipe body is formed into the closing plug with a certain intensity after being stretched, the closing plug closely fits with the pipe wall of the casing pipe, and therefore the heating pipe casing pipe can be automatically located without spot welding and be directly welded, a welding joint portion on the top end of the casing pipe body has no influence to a diameter of the casing pipe, and firmness of the welding joint portion is increased.
Description
Technical field
The utility model relates to the generator of absorption and diffusion type refrigerating box, particularly a kind of heating pipe sleeve pipe that is used for the generator of absorption and diffusion type refrigerating box.
Background technique
As everyone knows, the generator of absorption and diffusion type refrigerating box comprises interior pipe, outer tube and heating pipe sleeve pipe, and the heating pipe sleeve pipe pastes with interior pipe mutually, in the heating pipe sleeve pipe, places internally liquid heat in the pipe of heater, makes the generator can proper functioning.
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; This small iron plate just can carry out welding processing, otherwise can't fix after must fixing through some heel pipe; Inefficiency and be difficult for centering; Be easy to weldering partially, weld joint postwelding on outer diameter side has increased pipe diameter, influences the assembling of heating pipe sleeve pipe and generator outer tube.
Summary of the invention
The utility model has overcome the deficiency that exists in the above-mentioned existing technology, 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.
The technological scheme of the utility model is achieved in that
A kind of heating pipe sleeve pipe; Comprise sleeve body, be provided with iron plate in the bottom of sleeve body, 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 the edge and the sleeve body of iron plate weld together.
Originally the opening end at heating pipe sleeve pipe top is not through handling; 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 behind the unnecessary metal could normal mounting, greatly reduces efficiency.As preferably, the top of sleeve body is the enlarging that forms through punching press.Heating pipe ferrule openings place and generator outer tube are closely cooperated conveniently to be welded; And even have excess metal to stay in the mouth of pipe during welding, the insertion that also can not influence heater is installed.Sleeve pipe is centralized positioning more easily also, has guaranteed that the gap around the heating pipe sleeve pipe is around liquid is full of, thereby uniform heating promotes interior pipe, and the protection heat does not run off.
Adopted the beneficial effect of the utility model of technique scheme to be:
Be formed with the closing cock of certain intensity after the iron plate of the utility model heating pipe sleeve bottom closed end is stretched; Closing cock and cover tube wall close-fitting; Do not need spot welding just can locate voluntarily; Directly can weld and the weld joint on the top of sleeve pipe to the not influence of diameter of sleeve pipe, increased the fastness of weld seam simultaneously.

Fig. 3 is the structural representation of heating pipe sleeve pipe.
Embodiment
The embodiment of the utility model is following:
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 that forms through punching press.
Claims (2)
1. heating pipe sleeve pipe; Comprise sleeve body, be provided with iron plate in the bottom of sleeve body, it is characterized in that: 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 the edge and the sleeve body of iron plate weld together.
