Description
Technical field
The utility model relates to the baffler field, especially relates to a kind of a kind of stainless steel baffler for the coolant noise of eliminating the air conditioner refrigerating pipe-line system.
Background technique
The baffler of existing refrigeration pipe system is a kind of parts that not only air-flow was passed through but also can effectively reduce noise, and it comprises the bigger hush pipe of a diameter and is welded in hush pipe two ends diameter less suction tude and steam outlet pipe.The hush pipe of traditional baffler, suction tude and steam outlet pipe all adopt copper pipe to make, because copper product price height makes that the baffler cost is higher; Occurred a kind of irony hush pipe on the existing market and copperly advanced, the baffler that steam outlet pipe is welded, by ferrous material instead of copper material, saved cost, but the baffler outer wall of irony needs the rust prevention by applying liquid material layer, the resin layer material is generally rust proof paint or rust proof paint, this this material causes environmental pollution easily in spraying process, and the baffler inwall is not to be coated with resin layer, therefore, still corrosion gets rusty easily, and refrigeration agent is good washing agent, and during baffler inner refrigerant circulation, iron rust is easy to peel off back being transported in other refrigeration parts with refrigeration agent and damages miscellaneous part.
Application publication number CN102338257A patent of invention discloses a kind of refrigeration system stainless steel baffler, the baffler of this structure comprises hush pipe and is welded in suction tude, the steam outlet pipe at hush pipe two ends, the hush pipe diameter is greater than suction tude and steam outlet pipe, steam outlet pipe gos deep into the hush pipe inner chamber, suction tude and steam outlet pipe are copper pipe, and described hush pipe material is stainless steel.This patent replaces with Stainless Steel Tube with the hush pipe material, and Stainless Steel Tube intensity height, and price is lower than copper pipe, and therefore overall cost is lower, but the baffler of this kind structure, air-flow is after suction tude enters the hush pipe, go deep into the hush pipe inner cavity at steam outlet pipe, easily produce eddy current, hinder flowing of air-flow, make baffler produce bigger pressure and fall, reduced the refrigeration efficiency of air conditioner.
Summary of the invention
It is high or easily get rusty that purpose of the present invention will overcome above baffler cost exactly, or the air-flow that passes through when using easily produces eddy current and the big defective of the pressure loss provides a kind of cost relatively low, a kind of baffler that usability is good.
For achieving the above object, baffler of the present utility model, comprise hush pipe and the suction tude, the steam outlet pipe that are welded in the hush pipe two ends, the hush pipe diameter is greater than suction tude and steam outlet pipe, suction tude and steam outlet pipe are copper pipe, the hush pipe material is stainless steel, and described hush pipe is made of first silencing cavity and second silencing cavity, and the necking down by a rounding off between first silencing cavity and second silencing cavity links.
Preferably, the necking down of described rounding off is to form at hush pipe outer wall roll extrusion undergauge.
Preferably, the same size with second silencing cavity of first silencing cavity of described hush pipe.
Alternatively, first silencing cavity of described hush pipe is bigger than second silencing cavity.
Because hush pipe substitutes copper pipe with Stainless Steel Tube described in the above-mentioned baffler, and the Stainless Steel Tube of identical wall thickness is more much higher than copper tube compressive strength, therefore, during specific design, used Stainless Steel Tube is more many than copper pipe wall thickness, and the price of Stainless Steel Tube is less than half of copper tube, and its proportion is also little than copper, therefore overall cost reduces, and has avoided getting rusty of irony hush pipe using process.
Because the hush pipe in this baffler has first silencing cavity and second silencing cavity, and it has twice noise reduction, therefore, its erasure effect is better again; And there is not center protrusion in the silencing cavity streamline rounding off of whole hush pipe, therefore, when air-flow passes through baffler, is difficult for producing eddy current, and the pressure loss is less.
Description of drawings
Fig. 1 is the structural representation of baffler of the present utility model;
Fig. 2 is the stereoscopic figure of Fig. 1 baffler.
Embodiment
Describe the embodiment of the utility model baffler below with reference to the accompanying drawings in detail.Fig. 1 is the structural representation of baffler of the present utility model, Fig. 2 is the stereoscopic figure of Fig. 1 baffler, this baffler comprises suction tude 1, hush pipe 2, and steam outlet pipe 3, the diameter of hush pipe 2 is greater than suction tude 1 and steam outlet pipe 3, hush pipe is solid of rotation, made by stainless steel material, it has the first silencing cavity 2a and the second silencing cavity 2b, the first silencing cavity 2a and the second silencing cavity 2b link by the necking down 2c with rounding off, the necking down 2c of rounding off is that the outer wall at hush pipe 2 forms by the rotating rolling press undergauge, during concrete the making, the first silencing cavity 2a and the second silencing cavity 2b can be etc. big, also can be that the first silencing cavity 2a is bigger than the second silencing cavity 2b, for easy to make, preferentially recommend the first silencing cavity 2a and the second silencing cavity 2b etc. big; Because the diagram baffler is to use in the air conditioner refrigeration pipe, by air conditioner manufactory welded and installed, therefore, is welded with suction tude 1 and steam outlet pipe 3 at the two ends of hush pipe 2, for just welding with air-conditioner hose is convenient, suction tude 1 and steam outlet pipe 3 are made for copper pipe.For guaranteeing welding quality and the low cost of suction tude 1, steam outlet pipe 3 and hush pipe 2; the preferential furnace brazing of recommending air protection of its welding; used solder is spelter bronze; during concrete the welding; the control of brazier temperature is at 900 ℃～1060 ℃, and pipeline fitting passes through the speed of brazier at 0.25～0.6 meter/minute.
The manufacturing process of above baffler is such: the first step, and the hush pipe preparation, the Stainless Steel Tube of the hush pipe of intercepting design length, to Stainless Steel Tube two chamfers, two ends and middle part rotating rolling press reducing, and cleaning-drying; Second step, inlet/outlet control is equipped with, the intercepting design length into and out of pipe, and two chamfer, an end enlarging then, and get small salient point from interior radially outwardly projecting at the weld sidewall of the other end pipe end of flared end, small salient point can one, also can symmetry 2 or 3, last cleaning-drying; The 3rd step was assembling, the inlet/outlet pipe box is gone into the bronze wire weld-ring of solid-state ring-type, after be pressed into the hush pipe two-port, it supports by the small salient point on inlet/outlet pipe weld sidewall and makes the import and export pipe fastened to each other motionless with hush pipe, and the bronze weld-ring with solid-state ring-type moves to import and export pipe and hush pipe socket intersection then; The 4th goes on foot, welding, and in the tunnel stove of baffler by nitrogen hydrogen mixeding gas or pure hydrogen protection that assembles, the control of brazier temperature is controlled at 0.25～0.6 meter/minute by the speed of brazier at 900 ℃～1060 ℃; In the 6th step, leak detection checks that each weld of baffler welding back has not failure welding.
The inlet/outlet pipe of above baffler is made of copper pipe, therefore, when baffler uses, the welding on itself and air-conditioning copper pipe road, the same good welding performance with copper baffler.
