Description
Technical field
The utility model belongs to refrigeration system pipeline technical field, especially relevant with a kind of refrigeration system pipeline aluminium branch pipe.
Background technique
Refrigeration pipe branch pipe is that its structure mainly uses threeway or multi-pass connecting joint connecting circular tube for a road medium input being divided into the connecting pipeline of two-way and the output of above medium in refrigeration pipe.The multiple-pass joint of existing branch pipe adopts copper pipe punching press to make, its manufacturing process is mainly the pipe using diameter larger, reducing is carried out as input hole in one end, make its internal diameter slightly larger than supplying tube, the other end re-uses punch ram after using multiple cylinder mold interval to insert pipe inner chamber, connect after both sides tube wall between multiple cylinder mold is caved in, form the multiple holes suitable with cylinder mold diameter as delivery outlet, again input copper pipe and output copper pipe insertion input hole and delivery outlet are welded, solder flux infiltrates between pipe and hole wall, also penetrate into and connect the gap between tube wall simultaneously.Because such branch pipe adopts tube stamping to make, during punching press there is certain elastic recovery in metal pipe, and elastic recovery is also often inconsistent, the hole tolerance of the delivery outlet causing punching press to be made is difficult to control, varying aperture amount is large, and input hole is mostly little tubaeform in aperture, makes flux distribution uneven, welding quality is unstable, and branch pipe soldering point easily ftractures; The metallographic structure at punching press position is damaged, easy trickle cracking under hyperbaric environment; All these make existing branch pipe resistance to compression strength poor, reveal incidence rate high.
Model utility content
The purpose of this utility model be intended to overcome the refrigeration pipe branch pipe resistance to compression strength that existing punching press makes poor, reveal the high defect of incidence rate, the refrigeration system pipeline aluminium branch pipe that a kind of firm welding, resistance to compression strength are large is provided.
For this reason, the utility model is by the following technical solutions: refrigeration system pipeline aluminium branch pipe, comprise a supplying tube, the multiple-pass joint of at least two output tubes and a connection supplying tube and output tube, described supplying tube and output tube are welded in input hole and the delivery outlet of multiple-pass joint respectively, it is characterized in that, described multiple-pass joint matrix is extruded aluminium alloy extrusions or the aluminium alloy castings of die cast, described input hole and delivery outlet cutting form on multiple-pass joint matrix, input hole and delivery outlet orifice end are all provided with one section of socket, supplying tube and output tube plug-in mounting are welded in corresponding socket.
In above-mentioned aluminium branch pipe structure, the sidewall of described socket is the cylndrical surface that on input hole and delivery outlet hole wall, footpath concaves, formed towards the axial end shoulder in aperture, same socket is isometrical in the axial direction, with described axial end shoulder for supplying tube and output tube welding plug-in mounting location end face, make supplying tube and output tube plug-in mounting location conveniently, and flux distribution can be made even, improve welding fastness.
The delivery outlet quantity of described multiple-pass joint is two, then output tube quantity is also two, and input hole center line is equal with the distance of two delivery outlet center lines.
Multiple-pass joint outer side wall between two delivery outlet center lines is two planes, ensures that the hole wall between two delivery outlets has enough intensity.
The utility model is by adopting extruding aluminium alloy sectional or pack alloy foundry goods to be matrix, shaping by stock removal input hole and delivery outlet make aluminium multiple-pass joint, following beneficial effect can be reached: 1, resistance to compression strength is high, disclosure risk is little, the intensity of extruded aluminium section is high, input hole and delivery outlet adopt cutting to make, make the pore wall thickness between two delivery outlets large, hole wall can not be subject to punching press damage, improve resistance to compression strength, the aperture, hole that cutting is made is consistent, precision is relatively high, solder flux is at supplying tube, between output tube and boring ratio in distribution uniform, improve welding fastness, all these is that aluminium branch pipe resistance to compression strength of the present utility model is high, disclosure risk is little, 2, improve manufacture up-to-standard rate, decrease waste of material, and the aluminium using price lower replaces the copper material that price is higher, reduces cost of material and processing cost.
