Oil equalizing pipe used for connecting compressors of air conditioner outdoor unit

Abstract

The invention discloses an oil equalizing pipe used for connecting compressors of an air conditioner outdoor unit. The oil equalizing pipe comprises an oil pipe and nuts, wherein the nuts are arrangedat both ends of the oil pipe and provided with inner threads; each nut with the inner threads is provided with a top inside; the top is provided with a plurality of through oil holes; one end of thetop is in a cone shape, is in the opposite direction of the oil pipe and faces the outside, while the other end is fixed on the inner threads of the nut; the nut corresponding to the cone-shaped partis provided with inner threads; the oil pipe is communicated with outside through the through oil holes; and one end of the top is provided with outer threads, and the top is screwed onto the inner threads of the nut through the outer threads and fixed on the nut. When a production line is connected, the nut of the oil equalizing pipe with the top is directly screwed into a connecting pipe, the sharp cone of the top bursts a rubber choke plug, and the oil equalizing pipe is communicated with the compressors through the plurality of through oil holes. The assembling process saves time and prevents leakage of compressor oil.

Description

technical field [0001] The invention relates to an air conditioner outdoor unit, in particular to an oil equalizing pipe used to connect compressors of the air conditioner outdoor unit. Background technique [0002] Generally, air conditioners are divided into integral air conditioners in which an outdoor unit and an indoor unit are arranged in one casing, and compressors and condensers are arranged in a casing outdoors as an outdoor unit, and an evaporator is arranged indoors as an indoor unit. split air conditioner. [0003] Recently, due to the increasingly higher requirements of the market for the refrigeration capacity of split-type air conditioners, in large-scale air conditioners, several compressors are equipped on the outdoor unit to effectively meet various refrigeration requirements. [0004] like figure 1 As shown, the outdoor unit 100 of the air conditioner in the prior art includes: a rectangular hexahedron-shaped casing 110 with an opening structure formed i...

Problems solved by technology

A connecting pipe 131 is provided on the lower part of the compressor 130, and a rubber plug (not shown) is set on the connecting pipe 131. When the production line is connected, the rubber plug on the compressor connecting pipe 131 needs to be removed first, and then a wrench is used to , connect the nut 133 with internal thread of the oil equalizing pipe to the connecting pipe 131, the above installation process is time-consuming and accompanied by a large amount of compressor oil leakage
