Description
Technical field
The utility model belongs to the accessory field of gas-liquid separator, more particularly, relates to a kind of screen cloth seat of gas-liquid separator.
Background technology
Gas-liquid separator is arranged between air-conditioning refrigeration system compressor air suction end and evaporimeter, can be used for temporary transient stocking system return liquid, the safe speed that control liquid refrigerant and lubricating oil can be tolerated with compressor returns compressor, avoid liquid hit phenomenon occurs, the effect of filtration, oil return can also be played.The design in gas-liquid separator escape pipe bottom oil return hole is an of paramount importance link in gas-liquid separator design process.Due to cold-producing medium and refrigeration lubrication oil dissolve each other or half molten, even if be provided with gas-liquid separator on the gas exhaust piping of air-conditioning, lubricating oil still can be carried secretly system cooling system in running, separate out along with the change (liquid change gaseous state) of cold-producing medium phase just has lubricating oil in evaporimeter, the lubricating oil of separating out is entrained into gas-liquid separator along with the high velocity air of hot fluorine defrosting, and is separated the bottom accumulating in gas-liquid separator.In order to make this part lubricating oil under actual operating mode, successfully can return compressor, a spill port must be bored bottom escape pipe, lubricating oil is sucked under negative pressure, returning compressor by certain return-air speed band, play the effect of lubrication.In addition, for preventing spill port from being blocked by intrasystem impurity, need at the position welded mesh seat in gas-liquid separator escape pipe bottom oil return hole.
Pass through patent retrieval, Chinese patent Authorization Notice No. CN 202281430 U discloses a kind of Novel gas-liquid separator, tank body is cylindrical, air inlet pipe, escape pipe is fixed on tank interior, escape pipe is that two length unequal pipe one connect in approximate " U " shape, i.e. side long tube opposite side short tube, its short tube is placed in tank interior, its long tube passes tank body and stretches out outside tank body, on the long tube of escape pipe, height and position place identical with short tube has 1 oily balance pipe, the bottom centre position place of escape pipe has 1 spill port, escape pipe short tube has spill port, the volume of this utility model gas-liquid separator is little, diameter is little, escape pipe short tube has been offered 4-6 spill port, but spill port does not weld screen pack, easy blocking.
Chinese patent Authorization Notice No. CN201852380U discloses a kind of gas-liquid separator for air conditioner, comprise vertical enclosed container, gas-liquid mixed refrigerant inflow pipe and vapor phase refrigerant effuser, feature is that the inner bottom part of described vertical enclosed container is provided with permanent magnet for adsorbing refrigerant and compressor oil Mixed Zone impurity, in this utility model, when accumulated impurities is arranged at the bottom of vertical enclosed container, can utilize permanent magnet such as the physical characteristic of magnetite that impurity is tightly adsorbed on magnetite surface, when there is non-steady state in system, although can disturbance be formed at the bottom section of vertical enclosed container, as long as but within the scope of the magnetic field intensity of magnetite, just can prevent impurity disengaging magnetite surface from flowing through spill port and get back to compressor, thus prevent the infringement to air-conditioning system core component compressor, but the permanent magnet of this gas-liquid separator for air conditioner inner bottom part can only the impurity of adsorbing metal class, and the susceptible to plugging problem of spill port is not well solved.Especially liquid refrigerant easily enters the pipeline of gas-liquid separator, causes liquid hammer to compressor, thus damage compressor, reduce its life-span.
