Description

Oil separator three-way pipeline joint Technical Field The utility model relates to the field of oil separators, in particular to a three-way pipeline joint of an oil separator. Background The oil separator is a key component of the compression refrigeration cycle for separating the lubricating oil carried in the compressor discharge air, preventing the lubricating oil from excessively entering the evaporator/condenser to cause a decrease in heat exchange efficiency. The oil outlet pipe is required to stably return the separated lubricating oil to a crankcase or an oil collector of the compressor, and meanwhile, the functional requirements of dynamic oil return control, oil path safety assurance, impurity filtration and the like are required to be met. In order to ensure the reliability of the system, the oil treatment capacity is improved to adapt to high-load working conditions, two groups of side-by-side oil separators are sometimes arranged in the compressor system, the two groups of oil separators are connected in a pipeline mode, and in the process, the structure of the pipeline for connecting the two groups of oil separators is optimized to meet the working requirements by considering the symmetry (ensuring the oil return resistance balance of the two oil separators), the flow direction and the space adaptation of the two groups of oil separators. Disclosure of utility model The utility model aims to provide an oil separator three-way pipeline joint and a compressor with the one-way valve, so as to solve the problems in the prior art. The three-way pipeline joint of the oil separator comprises a lower branch pipe, three-hole joints and a straight pipe, wherein the lower branch pipe comprises a first pipeline and a second pipeline which are symmetrically arranged on two sides of the three-hole joints, the top of the lower branch pipe is inserted into the three-hole joints, the bottom of the straight pipe is inserted into the three-hole joints, and the bottom of the lower branch pipe is inserted into a one-way valve at the top of the oil separator. Preferably, the bottom of the lower branch pipe is a straight pipe with a vertical downward direction, the upper end of the lower branch pipe is an inclined pipe, and an included angle between the inclined pipe and the straight pipe is 100-130 degrees. Preferably, the straight section pipeline and the inclined pipeline are connected in a smooth manner through the arc section pipeline. Preferably, the three-hole connector comprises a first hole vertically upwards, and a second hole and a third hole symmetrically arranged on two sides of the first hole. Preferably, the diameter of the lower end of the straight pipe is smaller than that of the upper end of the straight pipe, and the diameter of the upper end of the straight pipe is used for connecting an external pipeline. Preferably, the lower branch pipe and the three-hole joint are made of stainless steel. Preferably, the straight tube is made of copper. Compared with the prior art, the utility model has the beneficial effects that: the utility model realizes the connection of the two groups of oil separators through the inverted Y-shaped three-way pipeline joint, replaces the pipeline and valve connection mode in the prior art, and meets the requirements of symmetry, flow direction and space adaptation of the two groups of oil separators.
