These terms are only used to distinguish one element from another. Thus, a first element could be termed a second element without departing from the teachings of the present application.

[0023] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood, however, that the present application can be presented in many different forms and should not be limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals indicate the same or functionally similar elements.

[0024] Figure 1 A kind of busbar pollution structure, main effect is to gather the pollution of each stage of compressor and discharge into the collection bucket 40. First control valve 10 and second control valve 20 are connected with the pollution of one stage of compressor respectively, and the pollution of two stages is gathered to a road by the flow joint 30.

[0025] Figure 2 The structure of the flow joint is shown, including coaxial high-pressure connector 32 arranged at both ends, and at least one low-pressure connector 33 is also provided on the side wall in the radial direction, and the low-pressure connector 33 is perpendicular to the high-pressure connector 32. So that the high-pressure gas-liquid mixture enters and exits the collection connector 30 along the linear trend through the high-pressure connector 32, and the low-pressure gas-liquid mixture flows out together after converging with the high-pressure gas-liquid mixture after entering the collection connector 30, which can minimize the fluctuation caused by the convergence of the gas-liquid mixture in the collection connector 30.

[0026] In one embodiment, the low-pressure connector 33 is designed as a quick plug connector structure, which is directly inserted into the low-pressure connector 33 for fixation by setting a quick plug connector 34 at the end of the low-pressure pipeline 51.

[0027] In one embodiment, the high-pressure connector 32 is designed as a threaded connector structure, and the high-pressure pipeline 52 needs to be fixed on the collection connector 30 by matching the end threaded connector, to ensure the stability of the high-pressure pipeline 52.

[0028] Figure 3 The structure of the collecting bucket is shown, mainly including a first interface 41 connected with the collecting joint 30 and a second interface 42 for emptying. Since the gas-liquid mixture sprayed from the side of the collecting joint 30 has a certain pressure, an additional emptying port is needed. Further, considering that the gas-liquid mixture with pressure is discharged into the collecting bucket 40, vibration is caused, and the working noise can be reduced by setting a silencer at the second interface 42.

[0029] In a preferred embodiment, the first control valve 10 and / or the second control valve 20 adopts one of an electromagnetic valve or a pneumatic valve. Since the upper end blowdown has a certain pressure, although the independent electromagnetic valve can accurately control the pipeline on-off, the valve body with high precision may not be able to withstand the pressure for a long time, and therefore the use of a linkage pneumatic valve can improve this problem.

[0030] The main use of this flow structure is for 300Bar air compressor systems with a flow less than 0.5m³ / min. The air compressor of this model has a small blowdown flow, and through the simple flow structure, the multi-stage shunt blowdown can be realized.
