Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
Embodiment one.
As shown in Figure 1, a kind of improved gas-liquid separator, including cylinder 3 and oil return pipe 8.It is equipped with and stretches out in the cylinder 3
The inlet pipe 1 and outlet pipe 5 of its top cover.The inlet pipe 1 flows into the cylinder 3 for refrigerant ecto-entad, and the outlet pipe 5 is for refrigerant
The cylinder 3 is flowed out from inside to outside；The inlet pipe 1 is straight tube, and the outlet end of lower end is located at the top of the cylinder 3；Institute
Stating outlet pipe 5 is straight tube, and the arrival end of lower end is located at the top of the cylinder 3.Preferably, the outlet end of the inlet pipe 1 and
Distance of the arrival end of the outlet pipe 5 away from 3 top cover of cylinder is the 1/8-1/5 of 3 height of cylinder, it is possible to reduce material
Material, reduces cost, moreover, it is also possible to which liquid refrigerant is effectively avoided to enter the outlet pipe 5.
3 bottom cover of cylinder is equipped with oil return opening 7.The oil return pipe 8 is set to except the cylinder 3, input end with
The oil return opening 7 is connected, and outlet end is connected with the air entry of the compressor, can make to be deposited on shown 3 bottom of cylinder
Lubricating oil flows back into compressor through the oil return opening 7 and oil return pipe 8.Preferably, the oil return pipe 8 is logical equipped with that can control it
Disconnected oil return solenoid valve 4 can control recirculating oil quantity by opening and closing the oil return solenoid valve 4, meet under unit difference operation conditions
Oil return needs.
When operation, dissolved with the gas-liquid two-phase mixed state refrigerant of lubricating oil, enter cylinder from inlet pipe, and in centrifugal force and again
It is separated under power effect, so that lighter gaseous refrigerant is in the top of cylinder, and flow back to after the cylinder is discharged from outlet pipe
Compressor.And heavier liquid refrigerant and lubricating oil are then in the middle and lower part of cylinder, can avoid liquid refrigerant and largely flow back
Compressor and cause liquid hammer.When system detection to compressor is in oil starvation state, openable oil return solenoid valve makes cylinder body bottom
Lubricating oil compressor is entered by oil return pipe, realize quick oil return.
Embodiment two.
As shown in Fig. 2, the present embodiment and the main distinction of embodiment one are: being equipped with vertical tube 9 in the cylinder 3；This is perpendicular
The lower end of pipe 9 is connected with the oil return opening 7, and the upper end is open, and its underpart is equipped with the first oil outlet 10, can be in oil return solenoid valve
After 4 open, lubricating oil is made to enter the oil return pipe 8 by first oil outlet 10.The bore of the vertical tube 9 and oil return opening 7
Sizableness.The diameter of first oil outlet 10 is less than the diameter of the oil return opening 7, and oil return control can be made more accurate,
Moreover, it is also possible to which the oil return solenoid valve 4 is made to keep opening for a long time, control program is reduced, operation is simplified.Meanwhile it is described perpendicular
The upper port of pipe 9 is in the top of the cylinder 3, and the vertical tube 9 can be largely entered to avoid liquid refrigerant.Preferably, described
One can be made with the oil return pipe 8 in vertical tube 9, pass through the oil return opening 7, and with 7 firm welding of oil return opening.
Embodiment three.
As shown in figure 3, the present embodiment and the main distinction of embodiment two are: the outlet pipe 5 is that U is tubular, and bottom connects
The bottom cover of the nearly cylinder 3.The bottom of the outlet pipe 5 is equipped with the second oil outlet 11, can make the portion for being deposited on 3 bottom of cylinder
Lubricating oil of sharing in the benefit by second oil outlet 11 enters the outlet pipe 5, then with gaseous refrigerant flows back to compressor.This second
The diameter of oil outlet 11 is suitable with the diameter of the first oil outlet 10, can close oil return solenoid valve 4 in unit low-frequency operation,
Oil return is only carried out by second oil outlet 11, thus, energy consumption can be reduced, operation is simplified.When compressor oil starvation, can open back
Solenoid 4 increases recirculating oil quantity, meets compressor by 11 oil return simultaneously of first oil outlet 10 and the second oil outlet
Operation demand.The arrival end of the outlet pipe 5 is in 3 top of cylinder, can effectively avoid liquid refrigerant largely enter it is described
Outlet pipe 5 and cause compressor return liquid risk.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
