Abstract
The utility model relates to a connection unit of a heat exchanger tube sheet and a half-sphere sealing head, which is incorporated by the half-sphere sealing head edge and the pipe board bottom. The utility model is characterized in that the wall thickness of the sealing head of the half-sphere sealing head is the minimum and the wall thickness of the edge of the half-sphere sealing head is gradually increased. The utility model has the advantages that: firstly the wall thickness of the half-sphere sealing head is distributed reasonably so as to reduce the weight and cost of the sealing head; secondly the processing workload of the half-sphere sealing head is reduced so as to shorten the production period and improve the production efficiency; finally the stress concentration at the welding position of the sealing head and the tube sheet is reduced so as to reasonably control the stress distribution of the sealing head and the tube sheet, prolong the service life of the heat exchanger and enhance the safety of heat exchanger.
Description
Technical field
The utility model relates to the jockey of a kind of heat exchanger tube sheet and hemispherical head, is mainly used in all kinds of shell-and-tube exchangers of power station industry, chemical industry, belongs to the heat exchanger technical field.
Background technology
Shell-and-tube exchanger is that the at present conventional mesolow shell-and-tube exchanger of heat exchanger that utilizes heat exchanger tube to carry out exchange heat between tube side and the shell side adopts flange to realize and being connected of tube sheet, but in large-scale high-voltage tube shell-type exchangers, adopt flange arrangement promptly to increase manufacturing cost, increased the leakage point of heat exchanger when operation again.But to concentrate with the stress of hemispherical head weld be an individual outstanding problem to tube sheet all the time when adopting Welding Structure, this point is the weak spot of entire product stress distribution, conventional way is that the minimum thickness that increases hemispherical head reduces stress, but so but increased the weight of hemispherical head, improved manufacturing cost, and hemispherical head also had a large amount of machining, and greatly increased the workload that product is made, prolonged the production cycle.
Summary of the invention
The purpose of this utility model provides the jockey of a kind of simple and effective shell-and-tube exchanger tube sheet and hemispherical head, and it has at first reduced the weight of hemispherical head, has reduced cost; Secondly, processing capacity be can reduce, manufacturing cost and production cycle reduced end socket; Also solved the inequality of stress distribution at last effectively, made stress distribution be tending towards rationally having prolonged the life-span of product.
For realizing above purpose, the technical solution of the utility model provides the jockey of a kind of heat exchanger tube sheet and hemispherical head, connect to form by hemispherical head edge and tube sheet bottom, it is characterized in that, the end socket place of described hemispherical head is a minimum wall thickness (MINI W.), and edge's wall thickness progressively thickens.
The utility model draws the ideal thickness of the required minimum wall thickness (MINI W.) of hemispherical head and hemispherical head and tube sheet junction by stress analysis, then by steel plate being struck out effective control of hemispherical head, make hemispherical head when punching press, form the edge partial thickening, make the thinnest part of hemispherical head satisfy the required minimum wall thickness (MINI W.) of hemispherical head, and edge has satisfied the ideal thickness that is connected with tube sheet.Because the junction of heat exchanger tube sheet and hemispherical head is the place that stress is concentrated the most, by adopting this structure, can make full use of the machine-shaping process of end socket, has at first reduced the weight of end socket, has saved material; Secondly, reduced processing, improved production efficiency end socket: last, make the stress distribution of hemispherical head and tube sheet very reasonable again, prolonged service life, improved security of products.
Compared with prior art, the beneficial effects of the utility model are: at first reasonably distributed the wall thickness of hemispherical head, alleviated end socket weight, reduced cost; The labor content that next has reduced hemispherical head has shortened the production cycle, has improved production efficiency.Reduce the stress of end socket and tube sheet weld at last and concentrated, reasonably controlled the stress distribution of end socket and tube sheet, prolonged the service life of heat exchanger, the security that has improved heat exchanger.
Description of drawings
Fig. 1 is the jockey structural representation of a kind of heat exchanger tube sheet and hemispherical head.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, jockey structural representation for a kind of heat exchanger tube sheet and hemispherical head, the jockey of described heat exchanger tube sheet and hemispherical head is connected to form by hemispherical head 1 edge and tube sheet 2 bottoms, the end socket place of described hemispherical head 1 is a minimum wall thickness (MINI W.), its wall thickness is 50-300mm, and edge's wall thickness progressively thickens and is 60-320mm.
The utility model tube sheet adopts Welding Structure with being connected of hemispherical head, at first calculate the minimum wall thickness (MINI W.) of hemispherical head: secondly draw the desirable radius in tube sheet arc transition district and the ideal thickness of hemispherical head and tube sheet junction, and the minimum wall thickness (MINI W.) of hemispherical head is checked by stress analysis according to design pressure, design temperature, product diameter and the material of shell-and-tube exchanger; The last forming technology of making end socket according to the minimum wall thickness (MINI W.) and the desirable end socket edge wall thickness of hemispherical head, the selected steel plate thickness that is fit to the punching press hemispherical head, under most economical situation, satisfy the minimum wall thickness (MINI W.) of end socket and the desirable wall thickness at end socket edge with the hemispherical head after guaranteeing to be shaped, and between forms rational transition automatically, reduces because the end socket stress that uneven thickness produces is concentrated.
Claims (2)
1. the jockey of heat exchanger tube sheet and hemispherical head is connected to form by hemispherical head (1) edge and tube sheet (2) bottom, it is characterized in that the end socket place of described hemispherical head (1) is a minimum wall thickness (MINI W.), and edge's wall thickness progressively thickens.
2. the jockey of a kind of heat exchanger tube sheet according to claim 1 and hemispherical head is characterized in that, the end socket place minimum wall thickness (MINI W.) of described hemispherical head (1) is 50-300mm for its wall thickness, and edge's wall thickness progressively thickens and is 60-320mm.
