Embodiment

[0024] When the recovery machine is in the self-cleaning mode, turn the knob 9 and drive the corresponding porous valve ball 12 to rotate through the driving and driven gears 10 / 11 and change the passage direction of the internal pipeline channel 13, so that the porous valve ball 12 is located at In the self-cleaning position, during the rotation process, the compressor 3 passes through the condenser 4, and then is compressed by the compressor 3 and is directly discharged from the output port of the compressor 3. During the whole process, the self-cleaning function is realized only by rotating the porous valve ball 12 . In the entire air channel, only the compressor 3 and the condenser 4 are externally installed, and the rest are located in the integrated control valve 2, thereby reducing the weight, volume and cost of the whole machine.

[0025] The above-mentioned technical solution is an example of a single-cylinder compressor, and can also be extended to double-cylinder, t...

Abstract

The invention discloses a refrigerant recycling machine, and provides a portable low-leakage refrigerant recycling machine which is compact in structure, fewer in leak points, low in cost and high in quality and performance stability, which solves the technical problems of the prior art that the connection pipeline is easy to leak, the purchase cost and the assembling cost are high, the overall size is large, and the like. The portable low-leakage refrigerant recycling machine comprises a shell and a compressor which is arranged in the shell, wherein one end of the compressor is provided with a fan, the other end of the compressor is provided with a condenser, an air cylinder cover of the compressor extends to be provided with an integrated control valve, the integrated control valve is provided with a condenser pipeline interface which is in butt joint with the condenser as well as an input interface and an output interface extending out of the shell, a plurality of inner pipeline passages are arranged in the integrated control valve, and the input interface and the output interface are communicated with an air cylinder of the compressor and the condenser through the inner pipeline passages.

Description

technical field [0001] The invention relates to a refrigerant recovery machine, in particular to a portable low-leakage refrigerant recovery machine with compact structure and few leakage points. Background technique [0002] With the strengthening of people's awareness of environmental protection and the continuous rise of refrigerant prices, refrigerant recovery machines have become increasingly popular and used. Refrigerant recovery machines are generally composed of shells, compressors, fans, condensers, etc., and the control valve passes through several copper The tube connects the various components, and there are many copper pipes. After the copper pipe joints are reamed, they are manually assembled. The assembly process is time-consuming and laborious, and the joints are prone to leakage, which increases the repair cost. It is also very easy to loosen the joints due to vibration and other reasons, resulting in leakage, which affects the quality and performance stabil...
