Abstract
The main object of the utility model is to provide a water heater inner bag that the welding seam is less, the quality is better, life is higher. In order to achieve the purpose, the utility model discloses a water heater inner bag constitutes for, including bucket, connection in the inner bag the right head of bucket one end, connection are in the inner bag the left head of the bucket other end in the inner bag, the right side head with the integrative spinning stretch forming of bucket in the inner bag, a left side head with bucket passes through welded connection in the inner bag.
Description
Technical field
The utility model relates to a kind of water heater liner.
Background technology
Two ends two end sockets of welding that existing water heater liner structure is bucket in inner bag form, the twice circumferential weld of one vertical masonry joint of bucket and end socket welding in having in the whole inner-tube structure.Shown in Figure 1 is the forming process of the water heater liner of prior art; As shown in Figure 1; This forming process comprises plate punching, reel, weldering vertical masonry joint (middle bucket), enlarging successively, comprises synchronously that with these operations end socket draws (stretching end socket), welds flange and hook respectively on end socket; Right with middle bucket group in to operation in group afterwards through above-mentioned operation, carry out weld-ring seam, weldering water pipe, weldering magnesium rod, weldering hanger, weldering T mouth, pressure testing afterwards successively.Adopt more welding sequence, welding quality receives the influence of various factors such as steel plate materials, welding protection gas, welding machine, frock clamp, operating personnel's level of skill, and the welding position is many more, and the quality control difficulty is big more.In addition; Need very high quality control cost; Per pass operation to welding is tested, and welding quality will directly cause the quality of enamel level, and because the enamel quality dissatisfaction that failure welding causes will cause inner bag effectively not protected by enamel; Cause the primer (steel plate) of the ladle body of inner bag to be corroded, to leak, thereby whole water heater is scrapped.
Thereby owing to above-mentioned water heater liner of the prior art is shaped through the multiple welding operation is arranged, thereby it is second-rate, and service life is lower.
The utility model content
In view of this, the main purpose of the utility model is, the water heater liner that a kind of weld seam is less, quality is better, service life is higher is provided.
For achieving the above object, the water heater liner of the utility model constitutes, and includes staving and the end socket that is connected the openend of this staving of the bottom tube-like of one spinning stretch forming.
Adopt the water heater liner that constitutes like this, because an end socket and staving are only arranged, so; Whole water heater liner has only the weld seam at end socket and staving one place; Technology is simple, and the whole quality of water heater liner is improved, thereby can have long service life.
The utility model is preferred, and said end socket is hemispherical, and heart position is formed with opening therein, is welded with flange at this opening part.
Because the opening part of end socket is welded with flange, can be through flange to the inner various parts such as heating tube sheet of installing of water heater liner.
The utility model is preferred, and said water heater liner also comprises water pipe, magnesium rod, hanger, T mouth.
The utility model is preferred, has enamel layer on said staving, the end socket.
Description of drawings
Fig. 1 is the key diagram of a kind of water heater liner forming process of the prior art;
Fig. 2 is the cutaway view of the water heater liner of an embodiment of the utility model;
Fig. 3 is the key diagram of the water heater liner forming process of above-mentioned embodiment.
The specific embodiment
Describe below in conjunction with the structure of accompanying drawing the water heater liner of the utility model specific embodiment.
Shown in Figure 2 is the cutaway view of the water heater liner 1 of this embodiment.As shown in Figure 1, water heater liner 1 has bucket 2 and right end socket 3 in the inner bag integrally formed through the spinning stretching.Bucket 2 left end is being through being welded to connect left end socket 4 in inner bag, left end socket 4 roughly radially centre be connected with flange 5, though do not express among the figure, flange 5 is through being welded to connect on left end socket 4.In addition, through hole 6 runs through flange 5 and left end socket 4.
The forming process of the water heater liner 1 of this embodiment is as shown in Figure 3, at first, and stretch forming left side end socket 4; And flange 5 is welded on the left end socket 4; With this two-step synchronously, stretch and bucket 2 and right end socket 3 in the inner bag of shaping integrative-structure through spinning, bucket 2 is right with 3 groups of right end sockets in the left end socket 4 that will be welded with flange 5 afterwards and the inner bag of this integrative-structure; Afterwards the two is welded together (weld-ring seam), weld water pipe, weldering magnesium pipe, weldering hanger, weldering T mouth, pressure testing afterwards.
In addition, though also not shown among the figure, have enamel layer on bucket 2, right end socket 3, the left end socket 4 in the inner bag of water heater liner 1.
Adopt as stated and the water heater liner 1 of this embodiment that constitutes; Because bucket 2 is integrally formed through the spinning stretching with right end socket 3 in the inner bag; Thereby can reduce the weld seam quantity of water heater liner 1; Reduced the adverse effect of weld seam, made the quality of water heater liner 1 be guaranteed, thereby improved service life enamel layer.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
