Abstract
The utility model discloses low stress cap formula cooler tube box belongs to the cooler tube box in a mainly used petrochemical field, and this kind of cooler tube box comprises parts such as business turn over oral siphon, tube sheet, tube box flange, cap, heat exchange tubes, and its characteristics are that the cap is by curved rounded rectangle and the conduct pipe incasement medium buffer space of making of sheet metal. This kind of cooler tube box's characteristics lie in: the coefficient of stress concentration of the reducible corner of rounded rectangle box structure reduces cap material cost, detachable apron easy access, and heat exchange pipe and pipe plate's welded joint is favorable to various measurings, the few effectual reduction weld quality accident of pipe case welding bead.
Description
Technical field
The utility model belongs to a kind of air cooling equipment for oil, chemical field, relates to a kind of low stress cap type air cooler bobbin carriage in particular.
Background technology
Air cooling heat exchanger (abbreviation air cooler) is a kind of energy-efficient cold exchange device, extensively practical in oil refining and chemical process, particularly in the area that water resource lacks, is characterized in water saving, economize on electricity, floor space is little, heat exchange efficiency is high.The existing air cooler bobbin carriage generally used can be divided into two kinds of structures, is threaded plug type bobbin carriage and the board-like bobbin carriage of removable cover respectively.
The material that traditional air cooler bobbin carriage is used is thick and heavy, and weld seam is many, welding job amount large, and the welded stress caused is large, yielding, and manufacturing cost is high.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of low stress cap type air cooler bobbin carriage, while meeting bearing strength, can reduce materials'use cost, reduce welding bead, be convenient to disassembly, cleaning.
For achieving the above object, a kind of low stress cap type air cooler bobbin carriage that the utility model provides is made up of parts such as inlet/outlet pipe, tube sheet, channel flange, cap, heat exchanger tubes, is characterized in that cap is bent into round rectangle by sheet metal and as medium cushion space in bobbin carriage.
The utility model has the advantage of: cap sheet metal used is bent into round rectangle, and round rectangle body structure can reduce the factor of stress concentration of corner, reduce cap material cost.Bobbin carriage welding bead effectively reduces weldquality accident less.
Dismountable cover plate easy access, the welding point of exchanger tubes and tubesheets is conducive to various detection.
Bobbin carriage is applicable to the use of various types of materials, particularly selects carbon steel material, improves the economic and practical of product.
Accompanying drawing explanation
Fig. 1 is general assembly structural representation of the present utility model.
Comprising: inlet/outlet pipe 1, tube sheet 2, channel flange 3, cap 4, heat exchanger tube 5, gasket seal 6, securing member 7.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, embodiment of the present utility model is described; the principle that the present embodiment is just described described in the present embodiment and description; the utility model is not limited to embodiment; be combined the expansion in field; the utility model will have and improve or change, these changes and to change will be all in claimed scope.
A kind of low stress cap type air cooler bobbin carriage, cap 4 be bent into type by thin-walled steel plate and with inlet/outlet pipe 1 assembly welding, cap 4 and channel flange 3 assembly welding, heat exchanger tube 5 and tube sheet 2 adopt exterior angle automatic TIG Welding Machine to connect, welding quality stable.The band cap round rectangle cover plate be made up of cap 4, inlet/outlet pipe 1, channel flange 3 and tube sheet 2 carry out fit sealing by gasket seal 6 and securing member 7, and form low stress air cooler bobbin carriage, bearing strength is better than seamed casing.
Claims (1)
1. a low stress cap type air cooler bobbin carriage, comprise inlet/outlet pipe (1), tube sheet (2), channel flange (3), cap (4), heat exchanger tube (5), gasket seal (6), securing member (7, it is characterized in that cap (4) sheet metal used is bent into round rectangle and as case in-vivo medium cushion space.
