Description
Technical field
The present invention is taken over by what new process was processed, more particularly to the stainless joint with clip butt welding, is applied to soldering
On plate heat exchanger, main feature is a simplified the processing technology taken over, and significantly reduces raw material and mach cost.
Background technology
Plate heat exchanger is that liquid-liquid, liquid-vapour carry out the ideal equipment of heat exchange, high with heat exchanger effectiveness,
The series of advantages such as heat loss is small, advantages of compact and light structure, small, the service life length of floor space, thus be widely used in it is metallurgical,
The departments such as mine, oil, chemical industry, electric power, medicine, food, chemical fibre, papermaking, light textile, ship, heat supply.Also, it can be used for adding
The various situations such as heat, cooling, evaporation, condensation, sterilizing, waste heat recovery.Plate heat exchanger mainly has detachable and welding
Formula two major classes, in comparison, welding type heat exchanger have many advantages, such as to hold that temperature, bearing capacity are strong, and resistance to corrosion is good, thus weld
Formula heat exchanger use scope is more extensive.
Welding type heat exchanger can be divided into half welding type heat exchanger, full welding type heat exchanger, plate visitor's formula heat exchanger, brazing sheet again
Formula heat exchanger.Since soldering has, heating temperature is relatively low, connector is smooth, tissue and mechanical performance change small, workpiece size
The advantages that accurate, brazing plate type heat exchanger can be used as condenser and evaporator in refrigeration industry, can be used as alcohol in chemical industry
The operating temperature range of cooler ... the pricker welded type heat exchanger of fermentation etc. is -160 DEG C~+225 DEG C, and working pressure range is
0.01MPa~3.2MPa.
Have inlet and outlet on pricker welded type heat exchanger, frequently with welding or expanded joint mode by its with take over one end phase
Connection, the take over other end is with external water inlet pipe, outlet pipe frequently with welding or clamp connection.It is used on existing brazing plate type heat exchanger
Take over and be mostly processed on numerically controlled lathe by tubing or solid round steel, and clip is all and welding take over butt welding
Together;For bigbore welded pipe, a large amount of material can not only be wasted using above-mentioned traditional processing method, processed
Cost is also special height.Therefore, a kind of in the case where ensureing that the normal uses such as take over intensity require there is an urgent need for proposing, what is more simplified connects
Pipe processing technique, to reduce raw material and mach cost.
Invention content
The technical problem to be solved in the present invention is, for taking over using tubing on traditional brazing plate type heat exchanger
Or solid round steel is processed on numerically controlled lathe, and due to clip all with take over to being welded together, for heavy caliber
Welded pipe processing when can waste a large amount of material, the shortcomings of processing cost is also special height, and processing technology is cumbersome, carries
Go out two kinds of take over stretch forming process for more simplifying and greatly reducing processing cost.
The present invention solves the above problems designed take over material as stainless steel, and take over endoporus is got through.Taken over top and
Bottom end is distinguished, and the ruler of the outer diameter of take over bottom boss and depth dimensions and counterbore at brazing plate type heat exchanger water-in and water-out nozzle
