Abstract

The utility model discloses a liner of a water heater and belongs to the technical field of water heaters. The liner of the water heater comprises a first drawn end socket and a second drawn end socket, wherein the first drawn end socket and the second drawn end socket are respectively formed by whole-plate drawing and are provided with openings, and the opening end of the first drawn end socket and the opening end of the second drawn end socket form a whole body by butt welding. According to the liner of the water heater, which is disclosed by the utility model, double end sockets are subjected to the whole-plate drawing to form a half liner state, and the liner is formed by once welding, so that the problems of complex welding, many welded junctions, higher cost and the like of the traditional liner of the water heater are solved.

Description

Water heater liner

Technical field

The utility model belongs to technical field of water heaters, specifically, relates in particular to a kind of water heater liner.

Technical field

The large capacity inner bag of water heater in the market is mostly welded by two first ladle bodies of envelope, and whole inner bag at least needs three road weld seams, is respectively ladle body straight weld, twice seal head girth weldering (as shown in Figure 1).There is following defect in this kind of water heater liner: 1, welding procedure complexity, and weld bond is many, and labor strength is large; 2, straight weld requires strictly, and operating difficulties is larger, and welding percent defective is large; 3, complex procedures, cost is high.

Summary of the invention

The utility model provides a kind of inner bag ladle body part to only have the water heater liner of a weld seam, to overcome the above-mentioned defect existing in prior art.

The main points of the technical solution adopted in the utility model are: a kind of water heater liner, comprise the first stretching end socket with opening and the second stretching end socket that form by whole plate stretching respectively, the openend of the openend of described the first stretching end socket and the second stretching end socket is by the butt welding entirety that is welded.

The diameter of water heater liner is greater than 300mm.

The tensile elongation of the first stretching end socket and the second stretching end socket is 30mm to 100mm.

Compared with prior art, the beneficial effects of the utility model are: the utility model adopts whole plate stretching double-seal head to become inner bag state half, disposable welding fabrication inner bag, the I of inner bag capacity is done 40 liters, maximum can reach 500 liters, and operation is simple, and weld seam exists hidden danger probability greatly to reduce, save human and material resources, reduce production costs thereby increase work efficiency.

Accompanying drawing explanation

Fig. 1 is the structural representation of water heater liner in prior art;

Fig. 2 is structural representation of the present utility model.

In figure, 1, ladle body straight weld; 2, seal head girth weldering; 3, the first stretching end socket; 4, the second stretching end socket; 5, end socket butt welded seam.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 1, in prior art, the large capacity inner bag of water heater is mostly welded by two first ladle bodies of envelope, and whole inner bag at least needs three road weld seams, is respectively ladle body straight weld 1, twice seal head girth weldering 2.

As shown in Figure 2, a kind of water heater liner, comprise that the first stretching end socket 3 with opening that forms by whole plate stretching respectively and second openend of stretching end socket 4, the first stretching end sockets 3 and the openend of the second stretching end socket 4 are by the butt welding entirety that is welded.

The diameter of water heater liner is greater than 300mm, and the tensile elongation of the first stretching end socket 3 and the second stretching end socket 4 is 30mm to 100mm, and the I of inner bag capacity is done 40 liters, and maximum can reach 500 liters.

Claims

1. a water heater liner, it is characterized in that: comprise the first stretching end socket (3) with opening and the second stretching end socket (4) that form by whole plate stretching respectively, the openend of the openend of described the first stretching end socket (3) and the second stretching end socket (4) is by the butt welding entirety that is welded.

2. water heater liner according to claim 1, is characterized in that: the diameter of described water heater liner is greater than 300mm.
