Abstract
The processing method for communicating internal container wall with external shell wall of double-layer stainless steel, vacuum heat-insulating container is characterized by that it uses a stainless steel tube to make it pass through the vacuum heat-insulating layer between internal container and external shell of said stainless steel vacuum heat-insulating container, and make it be connected with internal container wall and external shell wall, and makes the internal container cavity of the stainless steel vacuum heat-insulating container be communicated with exterior, and adopts the resistance projection welding or resistance seam welding method to make the internal container be connected together with stainless steel tube, and adopts the resistance seam welding method to make external shell be connected together with stainless steel tube.
Description
The present invention relates to a kind of processing method that the inside and outside wall pipe is communicated with in the double-layer stainless steel vacuum heat-insulating container, especially between the inner bag of double-layer stainless steel vacuum heat-preserving kettle or bottle sidepiece or bottom and shell, the processing method that pipe is communicated with is set.
Background technology:
The stainless-steel vacuum cool-bag is according to the function of its design, sometimes need between the inner bag of its sidepiece or bottom and shell, settle a communicating pipe, with inner bag and external communications, by communicating pipe the water in the internal bladder cavity being drawn or the lead of the electrical appliance installed in its inner chamber being drawn etc.Because between the inner bag of stainless-steel vacuum cool-bag and the shell is the vacuum layer structure, will pass vacuum layer communicating pipe is connected with shell with inner bag, the method of attachment of communicating pipe and inner bag and shell is for guaranteeing that stainless-steel vacuum cool-bag vacuum and heat-insulating property and presentation quality are all very important.Traditional connection processing method is to use the method for soldering that communicating pipe is connected with shell with inner bag.The method of soldering is divided by temperature three kinds: promptly be low temperature brazing, middle temperature brazing and high temperature brazing.The stainless-steel vacuum container need be heated to 500 ℃-600 ℃ when vacuumizing, if adopt low temperature brazing and middle temperature brazing method, because the weld seam fusing point is lower, during heating, can not bears negative pressure of vacuum reliably, and be difficult to use in actual production; If adopt the method for general high temperature brazing, weld seam can bear 500 ℃-600 ℃ temperature when vacuumizing, be difficult for produce leaking at the solder joint place phenomenon of vacuum, but the method for high temperature brazing, the high temperature in the time of can be because of high temperature brazing makes stainless steel surfaces produce oxide skin to cause being difficult for extracting out vacuum, therefore traditional high temperature brazing will be carried out in a vacuum, this causes the high temperature vacuum brazing investment big, the cost height, and work efficiency is low, poor reliability, the shortcoming that the while outward appearance can be out of shape.
Summary of the invention:
Can not guarantee big, the deficiencies such as cost is high, work efficiency is low, outward appearance distortion of the vacuum of stainless-steel vacuum cool-bag and presentation quality difference that heat insulation effect brings or investment in order to overcome soldering, the invention provides the processing method that a kind of stainless steel cool-bag inside and outside wall pipe is communicated with, the vacuum of stainless-steel vacuum cool-bag can not only be guaranteed, and the quality of outward appearance can also be guaranteed.
The technical solution adopted for the present invention to solve the technical problems is: a certain position is selected in sidepiece or bottom at stainless-steel vacuum cool-bag inner bag, make a call to a hole, the form in hole can be the flange hole, it also can be hole without turn-ups, the flange direction in flange hole can be inside, also can be outside, the diameter in hole equates with the external diameter of stainless steel communicating pipe.The shape of stainless steel communicating pipe, design according to ways of connecting, for the convenience that illustrates, this specification is an example with the sidepiece hole, stainless steel communicating pipe is inserted in the hole of inner bag, mode with resistance projection-welding or resistance seam welding is welded to connect stainless steel communicating pipe and inner bag, make a call to a flange hole in the shell of the stainless-steel vacuum cool-bag position corresponding with the inner bag hole, the diameter in flange hole equates with the external diameter of stainless steel communicating pipe, the direction of flange is outside, inner bag and shell are cooperated and be connected, be about to insert stainless steel communicating pipe in the flange hole of shell by what resistance projection-welding or resistance seam welding were connected inner bag, inner-tube mouth aligns with outer faucal and is connected with the method for welding, there be contacting of an anchor ring stainless steel communicating pipe with place, shell flange hole, with the method for resistance seam welding, the anchor ring contact position is welded to connect, be connected with the shell argon arc welding at the bottom of again band being vacuumized the exhaust of copper pipe.Like this, form a communication with cavity and outside passage between inner bag and the shell.When the vacuum machine by after vacuumizing copper pipe and vacuumizing, interlayer between inner bag and the shell is evacuated state and forms vacuum heat-insulating layer, is connected the outside that vacuum layer is communicated to internal bladder cavity the stainless-steel vacuum cool-bag of just passing stainless steel communicating pipe between inner bag and the shell by electric resistance welding.
The invention has the beneficial effects as follows and realize internal bladder cavity and outside being communicated with under the situation of the vacuum that guarantees the stainless-steel vacuum cool-bag, and method is easy, cost is low, can realize producing in enormous quantities.
