Abstract
The utility model discloses a sealing sheet used for welding, which comprises a metal sheet, wherein a sealing plug formed by stretching is arranged in the middle of the metal sheet, and the edge of the metal sheet forms a circular ring lapped with the mouth of a pipe. In the utility model, the sealing sheet is stretched to from the sealing plug with certain strength, the depth of the sealing plug is 0.5-1.2 cm, the sealing plug is plugged into the pipe to be closed fit with the pipe wall while in use, automatic positioning can be realized without spot welding, the circular ring at the edge of the sealing sheet can be directly welded, and the welding part has no influence on the pipe diameter at the top end of the pipe, and the firmness of the welding seam is increased.
Description
Technical field
The utility model relates to welding technology field, particularly a kind of closure plate that is used for the heating pipe sleeve pipe of absorption and diffusion type refrigerating box generator.
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, and an end of heating pipe sleeve pipe is closed, and prevents that liquid from flowing into sleeve pipe; 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 shape, the structure of iron plate in the above-mentioned existing technology have been done improvement, and a kind of closure plate that is used to weld welding, that improved working efficiency that is easy to assemble is provided.
The technological scheme of the utility model is achieved in that
A kind of closure plate that is used to weld comprises a tinsel, and described tinsel middle part is provided with the closing cock that drawn is processed to form, and the edge of tinsel is formed for the annulus with mouth of pipe overlap joint.
As preferably, the degree of depth of said closing cock is 0.5～1.2cm.Can guarantee to seal and be plugged with enough degree of depth and fill in the mouth of pipe.
Adopted the beneficial effect of the utility model of technique scheme to be:
The utility model is with the closing cock that is formed with certain intensity after the stretched processing of closure plate; The degree of depth of closing cock is 0.5～1.2cm; Closing cock is filled in the pipe and the tube wall close-fitting during use; Do not need spot welding just can locate voluntarily, the annulus at closure plate edge directly can weld and the weld joint does not influence the diameter of managing on the top of pipe, has increased the fastness of weld seam simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model closure plate;
Fig. 2 is the linkage structure schematic representation of heating pipe sleeve pipe and closure plate among the embodiment.
Embodiment
The embodiment of the utility model is following:
Embodiment: a kind of closure plate that is used to weld, as shown in Figure 1, comprise a tinsel 4, described tinsel 4 middle parts are provided with the closing cock 3 that drawn is processed to form, and the edge of tinsel 4 is formed for the annulus 2 with mouth of pipe overlap joint.
The application example of the utility model is following: for example a kind of heating pipe sleeve pipe; In use need an end be sealed; As shown in Figure 2, this heating pipe sleeve pipe comprises sleeve body 1, is provided with tinsel 4 in the bottom of sleeve body 1; The closing cock 3 of tinsel 4 is connected with sleeve body 1 tube wall close-fitting, and the annulus 2 that tinsel 4 edges form overlaps with sleeve body 1 mouth of pipe and welds together.
The closure plate of the utility model can be used for the mouth of pipe welding in a plurality of fields.
Claims (2)
1. a closure plate that is used to weld comprises a tinsel, it is characterized in that: described tinsel middle part is provided with the closing cock that drawn is processed to form, and the edge of tinsel is formed for the annulus with mouth of pipe overlap joint.
2. the closure plate that is used to weld according to claim 1 is characterized in that: the degree of depth of said closing cock is 0.5～1.2cm.
