Description
Technical field
The utility model relates to art of refrigeration units, is specifically related to a kind of rotary extrusion type spinning muffler.
Background technology
Muffler is air-conditioning refrigeration system vitals, is generally installed in air conditioner refrigerating pipeline, and the line cross section flowed through by refrigerant in flip-flop air-conditioning system amasss the noise reducing or eliminate refrigerant and produce in the flowing of pipeline high speed.
Conventional muffler adopts fine copper manufacture, copper is national strategy metal, procurement price is high, valency fluctuation, average price is at 50,000 yuan/ton for many years for the pure copper tube (TP2Y) of Φ 50, and with common steel tube (SPCC) cheap of bore, price fluctuation is little, average price is at 6000 yuan/ton for many years, is only 1/8 of copper material.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rotary extrusion type spinning muffler, solves the shortcoming that in prior art, overall employing fine copper cost is high, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of rotary extrusion type spinning muffler, comprise middle cylinder body and the air inlet pipe and the escape pipe that are arranged on middle cylinder body two ends, the sidewall of described middle cylinder body is provided with at least one groove to central concave, middle cylinder body is divided into the container of multiple connection, described air inlet pipe and escape pipe adopt pure copper material to make, middle cylinder body adopts stainless steel material to make, air inlet pipe and escape pipe and middle cylinder body are welded, outer surface entirety is sprayed paint or electrophoretic paint, or plated surface stainless steel composite bed.
Preferably, the sidewall of described middle cylinder body is provided with bloop.
Preferably, the sidewall of described middle cylinder body is double-decker, and double side walls is all provided with bloop.
Preferably, silencing cotton is provided with in described middle cylinder body.
Preferably, described middle cylinder body is provided with circular frame, and described silencing cotton covers in circular frame.
The beneficial effect of above technical scheme is adopted to be: the utility model has the advantage of: muffler body part adopts common steel tube (SPCC), does not adopt fine copper, reduces product material cost; Air inlet pipe and escape pipe still adopt pure copper material, do not change the connected mode of product and other pipeline fittings, do not affect the manufacturing process of rear operation; Product external surfaces entirety is sprayed paint or electrophoretic paint, or plated surface stainless steel composite bed, ensures non-corrosive in product use procedure.
On middle cylinder body, the structure of groove promotes the effect of noise reduction greatly, and the sidewall of middle cylinder body is double-decker, and audio frequency is through the noise reduction of bloop secondary, and reduce noise, be also provided with silencing cotton in middle cylinder body, silencing cotton can adsorb noise.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of embodiment 2.
Wherein, 1--middle cylinder body, 2--air inlet pipe, 3--escape pipe, 4--groove, 5--bloop, 6--silencing cotton, 7--circular frame.
Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment 1: as shown in the figure, a kind of rotary extrusion type spinning muffler, comprise middle cylinder body 1 and the air inlet pipe 2 and the escape pipe 3 that are arranged on middle cylinder body 1 two ends, described air inlet pipe 2 and escape pipe 3 adopt pure copper material to make, middle cylinder body 1 adopts stainless steel material to make, air inlet pipe 2 and escape pipe 3 are welded with middle cylinder body 1, and outer surface entirety is sprayed paint or electrophoretic paint, or plated surface stainless steel composite bed.
Embodiment 2: as shown in the figure, a kind of rotary extrusion type spinning muffler, comprise middle cylinder body 1 and the air inlet pipe 2 and the escape pipe 3 that are arranged on middle cylinder body 1 two ends, the sidewall of described middle cylinder body 1 is provided with at least one groove 4 to central concave, middle cylinder body 1 is divided into the container of multiple connection, described air inlet pipe 2 and escape pipe 3 adopt pure copper material to make, middle cylinder body 1 adopts stainless steel material to make, air inlet pipe 2 and escape pipe 3 are welded with middle cylinder body 1, outer surface entirety is sprayed paint or electrophoretic paint, or plated surface stainless steel composite bed, the sidewall of middle cylinder body 1 is double-decker, double side walls is all provided with bloop 5, middle cylinder body 1 is provided with circular frame 7, described silencing cotton 6 covers in circular frame 7.
Air inlet pipe and escape pipe adopt fine copper (TP2Y) material, and middle cylinder body part adopts common steel tube (SPCC) material, and air inlet pipe is connected with middle cylinder body by welding with escape pipe.After air inlet pipe and escape pipe weld with middle cylinder body, outer surface entirety is sprayed paint or electrophoretic paint protection, or overlay coating, or surperficial stainless steel composite bed, and middle cylinder body adopts spinning process reducing.
The utility model has the advantage of: muffler body part adopts common steel tube (SPCC), does not adopt fine copper, reduces product material cost; Air inlet pipe and escape pipe still adopt pure copper material, do not change the connected mode of product and other pipeline fittings, do not affect the manufacturing process of rear operation; Product external surfaces entirety is sprayed paint or electrophoretic paint, or plated surface stainless steel composite bed, ensures non-corrosive in product use procedure.
On middle cylinder body, the structure of groove promotes the effect of noise reduction greatly, and the sidewall of middle cylinder body is double-decker, and audio frequency is through the noise reduction of bloop secondary, and reduce noise, be also provided with silencing cotton in middle cylinder body, silencing cotton can adsorb noise.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
