Description
Technical field
The present invention relates to a kind of scroll air compressor is and in particular to a kind of air-breathing valve arrangement of scroll air compressor changes
Enter.
Background technology
Scroll air compressor is so that its efficiency high, noise be low, small volume, be conducive to the advantages of energy-conservation and environmental protection and wide
The general industries such as industry, agricultural, communications and transportation that are applied to need the occasion of compressed air.Scroll air compressor mainly runs part whirlpool
Disk only has engagement, does not produce abrasion, thus the life-span is longer than piston type, screw compressor, is pneumatic machinery ideal power source.
In scroll air compressor, main run part whirlpool disk and be divided in Moving plate and quiet disk, Moving plate and quiet disk set vortex piece, generally by moving
Disk and quiet disk are bonded to each other formation compression chamber, when Moving plate driven by bent axle make translation along certain circular path when, Moving plate is vortexed
Piece moves relative to quiet disk vortex piece, is moved by the compression chamber that both are formed and changes its volume, thus carrying out sucking, pressing
Contracting, discharge, complete the process of compressed air.
At the air entry of quiet disk, inlet valve is installed, suction filter is installed by inlet valve, inside screw compressor
With extraneous air isolation, when screw compressor operates, inlet valve is opened, and the suction filter installed on inlet valve prevents powder
Dirt, impurity and other big particle foreign matters enter inside compressor, play the effect of protection compressor operation.Work as screw compressor
When shutting down, inlet valve cuts out, and prevents screw compressor reversion operating, and protection compressor is injury-free.Prior art is vortexed empty
The inlet valve of air compressor is external monoblock type, needs switching part just can be arranged on quiet disk air entry, complex structure, cost
Higher.
Content of the invention
It is an object of the invention to provide a kind of simple, the compact inlet valve of structure, by the inlet valve directly suction with quiet disk

The built-in scroll air compressor of this inlet valve disclosed by the invention, including quiet disk and be connected at its air entry
Inlet valve.Inlet valve includes body and the valve element, valve element bearing and the spring that are connected in its axial central through hole；Valve element connects
In the upper end of valve element bearing, the bottom surface of valve element bearing is fixed in the upper end of spring；Body includes suction filter from top to bottom
The air-breathing of construction section, quiet disk air entry linkage section and valve element bearing linkage section, quiet disk air entry linkage section outer wall and described quiet disk
Mouth is directly connected to, and suction filter construction section is located at outside the air entry of quiet disk, and valve element bearing linkage section is located in quiet disk air entry,
There is the slotted eye for fixing lower spring end the bottom surface of described quiet disk air entry.
The suction filter construction section of described body, quiet disk air entry linkage section and valve element bearing linkage section external diameter subtract successively
Little, quiet disk air entry linkage section is threadingly attached on the air entry of described quiet disk, and suction filter construction section is inhaled with quiet disk
Gas port is packed with sealing ring between outer end.
The side wall of described suction filter construction section offers screwed hole and the oil-sucking hole of common longitudinal center line, oil suction hole position
In the inner of screwed hole, aperture is less than the aperture of screwed hole.
The side wall of described valve element bearing linkage section endoporus has the annular groove for connecting described valve element bearing, valve element bearing
It is connected in this groove, there is the cannelure of indent the outer end of valve element bearing, and described valve element is connected in this cannelure.
Lean on described body and offer air through hole at valve element.
The air-breathing offering indent at corresponding described air through hole on the hole wall of described quiet disk air entry avoids annular groove.
Pass through screw thread detachable connection between the quiet disk air entry linkage section of described body and quiet disk air entry.
The valve element of inlet valve, valve element bearing and spring are included in this internal, body directly air-breathing with quiet disk by the present invention
Mouth is connected so that valve element, valve element bearing and spring are located in air entry.Air-breathing is opened up on the air entry of quiet disk avoid
Annular groove, is effectively increased air-breathing flow area, prevents air-breathing from throttling.Compare with prior art, eliminate first reducing sleeve this zero
Part, saves on corresponding material cost and cost of labor certainly；The size of inlet valve accordingly reduces simultaneously, compact appearance.When
Inlet valve breaks down when needing to change, and directly unloads and then by new inlet valve by screw thread body from quiet Pan Xiqikouchu
Or mode connects for screw fastens, simple and convenient.
