Description
Technical field
The present invention relates to the air-conditioner hose connector.More particularly, the present invention relates to three kinds of pipeline connecting parts of muffler, filter, device for drying and filtering in the air-conditioner.
Background technology
Muffler, filter, device for drying and filtering are servicing units important in the air-conditioning equipment, its common ground is that the shape and the size of three devices is suitable, substantially all be tubular (cylindrical shell 1), and shell is all by red copper compacting by rolling, wherein, the muffler (see figure 1) has the port of export and arrival end with two kinds of footpath and reducings, it is installed in the effect of playing buffering in the refrigeration system, reducing pressure, thereby reaches the effect of noise reduction; The internal fixation of filter (see figure 2) has a filter screen rack 4, and a side of filter screen rack 4 is connected with filter screen twine 5, forms a space between filter screen rack 4 and filter screen twine 5.Filter is installed on the pipeline of associated components of refrigeration system capillary front end or is installed in the arrival end and the port of export of electric expansion valve, be used for collecting the solid impurity in refrigeration system and the lubricating oil, anti-locking system and capillary and expansion valve stop up, and guarantee that pipe-line system is unimpeded; The device for drying and filtering (see figure 3) in cylindrical shell near two ends be provided with filter screen twine 5,5 ' and be used to support the rack 4,4 of this filter screen ', two filter screen twines 5,5 ' between drier 6 (mostly being molecular sieve desiccant) is housed.But the dirt in both elimination refrigeration systems of device for drying and filtering, remaining small amount of moisture in the adsorbable again refrigeration system is to guarantee the unimpeded and refrigeration system operate as normal of capillary.At present these three devices are all by the fine copper manufacturing, and along with worldwide copper price is constantly high, manufacturing cost of air conditioner is also therefore constantly soaring, make domestic air-conditioner enterprise face very big predicament, also bring financial burden to the consumer.
Therefore on the market air-conditioner accessory product with the substitution material manufacturing of copper is existed demand.
Summary of the invention
The purpose of this invention is to provide improved air-conditioning duct connector one muffler, filter and device for drying and filtering.
Air-conditioner hose connector provided by the invention comprises cylindrical shell and is attached to the copper coupling part at cylindrical shell two ends that described cylindrical shell is made by magnesium alloy materials.As preferably, the two ends of described cylindrical shell respectively comprise the reducing of a diameter less than cylindrical shell, and described copper coupling part is attached in the described reducing.It can be attached to the inner surface of reducing, also can be attached to the outer surface of reducing.
In a specific embodiment of the present invention, described copper coupling part is the copper sheathing that is welded on described reducing inner surface or outer surface.Welding can be carried out with conventional method (for example soldering).
In another embodiment of the present invention, described copper coupling part is for electroplating the copper extra play on described reducing inner surface or outer surface.
Replacement form as the specific embodiment, above-mentioned copper sheathing can be replaced by the cover that the metal material that aluminum alloy sleeve or other are suitable for is made, and perhaps one of them is replaced by aluminum alloy sleeve or the cover made by other metal materials (outside copper removal, aluminium alloy, the magnesium alloy) that are suitable for.
As substituting of above-mentioned connected mode, described copper coupling part is the copper sheathing that is connected described reducing inner surface or outer surface by mechanical connection manner, and the example of mechanical connection manner is threaded, snap ring-type connection etc.In this connected mode, one deck can also be set by for example polytetrafluoroethylene (PTFE) or almag (preferred 5052 alloys between copper sheathing and reducing, 5052 alloy products of producing as the huge basic Aluminum in Shanghai Co., Ltd) pad or the sealing ring made of sealability material such as, for mechanical connection, this mode is preferred, because add the air-tightness that Upper gasket or sealing ring both can improve the junction, can avoid the contingent corrosion in junction again, play the effect of life-saving.
Air-conditioner hose connector of the present invention has three kinds, and it is respectively muffler, filter and device for drying and filtering.Its middle filtrator and device for drying and filtering all include the filter screen twine and are used for fixing the rack of filter screen twine in cylindrical shell, in specific embodiment more of the present invention, described rack is also made by magnesium alloy, and described filter screen twine is made by stainless steel material.
The present invention adopts magnesium alloy to make pipeline connecting parts, i.e. main part-the cylindrical shell of muffler, filter and device for drying and filtering is so the instinct that manufactures of pipeline fitting obviously reduces.Also alleviated the weight of air-conditioner in addition.The copper coupling part that is attached to the cylindrical shell two ends makes this accessory to be connected smoothly with other copper parts, this mainly be consider manufacturing firm when being assembled to it in air-conditioner still by welding this actual conditions that are connected with copper part, because the welding of copper and copper pipe fitting will be more copper and welding other material pipe fittings are much easier.Certainly, because situation about being connected with aluminium alloy part is also arranged, so, can be with its one or both ends affix aluminum alloy sleeve.Therefore, product provided by the invention not only cheaply but also easy to use.
