As shown in Figures 1 and 2, one embodiment of the invention provides a kind of compressor, including compressor body 100, power are adjusted
Component, orifice union 200 and valve 300 are saved, power adjusting component can drive guiding valve to be compressed machine work(by lubricating oil
The regulation of rate, orifice union 200 have oil inlet end and oil outlet end, and valve 300 includes oil inlet valve 310 and fuel-displaced valve 320, entered
The fuel-displaced side of fuel tap door 310 is removably connected with the oil inlet end of orifice union 200, and lubricating oil can pass through oil inlet valve 310
Into orifice union 200, the oil-feed side of fuel-displaced valve 320 is removably connected with the oil outlet end of orifice union 200, fuel-displaced valve
320 fuel-displaced side connects with power adjusting component.
Above-mentioned compressor, orifice union 200 pass through shape between oil inlet valve 310 and fuel-displaced valve 320 and other structures
Into dismountable connection, it is necessary to when changing orifice union 200, oil inlet valve 310 and fuel-displaced valve 320 only need to be closed in advance,
Then orifice union 200 is changed, and the leakage of lubricating oil and refrigerant will not be caused in Renewal process, saved maintenance into
This, does not pollute the environment yet.
Optionally, can be into the lubricating oil in orifice union 200 compressor lubricating system in lubricating oil, also may be used
It is the lubricating oil in independent oil circuit, the source of lubricating oil during the present invention is not intended to limit into orifice union 200.Can be real as one kind
Existing mode, compressor body 100 are provided with return line 400 outside, and valve 300 also includes oil return valve 330, return line
400 oil outlet end is removably fixedly connected with the oil-feed side of oil return valve 330, the fuel-displaced side of oil return valve 330 and compressor
The lubricating system connection of body 100, the oil-feed side of oil inlet valve 310 connects with the fuel-displaced side of oil return valve 330.By orifice union
200 oil inlet end is attached by oil inlet valve 310 and return line 400, and the lubricating oil in return line 400 is passed through into section
Flow component 200 and introduce power adjusting component to realize the regulation of compressor horsepower, reduce the quantity of oil circuit.Return line 400
Oil outlet end connected by oil return valve 330 with the lubricating system of compressor body 100, and return line 400 and oil return valve
It is to be removably fixedly connected between 330, when return line 400 needs to change due to aging or damaged in collision, can incites somebody to action
Oil return valve 330 is closed, and is then pulled down return line 400 and is changed, reduces the leakage of lubricating oil and refrigerant.
In the present embodiment, the type of valve 300 can be one kind in plug valve, ball valve, butterfly valve, stop valve, gate valve or
Several, the present embodiment is not intended to limit the particular type of valve 300, as long as can realize closing, open oil circuit and removable with oil circuit
The connection unloaded.Further, as shown in figure 3, the valve 300 used in the present embodiment is off valve, stop valve open with
And frictional force is small between sealing surface in closed process, durable, Lift is small, easy to manufacture, easy to maintenance.Further,
Stop valve is taper thread stop valve, and compared to common stop valve, taper thread stop valve has that sealing property is more preferable, interchangeability is strong
Advantage.
Orifice union 200 and guiding valve require higher for the clean-up performance of lubricating oil, and lubricating oil is anti-in compressor
Impurity may be infiltrated during multiple use, orifice union 200 can be blocked or even guiding valve is failed by infiltrating the lubricating oil of impurity,
As shown in figure 1, in one embodiment of the invention, oil strainer 500 is additionally provided with outside compressor body 100, lubricating oil leads to
Enter return line 400 after crossing oil strainer 500.Lubricating oil can together be compressed in the course of work of compressor with refrigerant,
