Revolve compressor.
Background technique
Screw compressor is widely used in automobile since it has many advantages, such as that energy-efficient, noise is lower, runs smoothly
In industry.Screw compressor is mainly formed by the dynamic and static vortex of two digamma function equation scrollworks is mutually ratcheting.Air-breathing, compression,
During exhaust work, fixed scroll is fixed on the rack, and movable orbiting scroll is driven by crankshaft and restricted by anti-rotation mechanism, surrounds quiet whirlpool
The Plane Rotation of very little radius is done at disk basic circle center, and gas sucks the periphery of fixed scroll, and with the rotation of eccentric shaft, gas is dynamic
Quiet disk engagement is closed gradually to be compressed in several composed crescent compression chambers, then by the axial hole of fixed scroll central module
Continuously send.
At work, compressed gas is discharged by fixed scroll central shaft hole to high pressure chest screw compressor.Compressor stops
After only working, since central shaft hole is connected to high pressure chest, high pressure gas is back to the damage that whirlpool disk component is be easy to cause in fixed scroll.
It is typically employed in setting spring leaf at gas vent in the prior art, and after compressor long-time use, spring leaf is easily deformed,
To lose sealing performance.
Utility model content
Based on problem and deficiency described in background technique, the utility model, which is intended to provide one kind, to prevent high pressure gas from flowing back
Screw compressor into fixed scroll.
In order to achieve the above objectives, the utility model uses following technical scheme:
A kind of screw compressor for preventing high pressure gas to be back in fixed scroll, including it is shell, end cap, fixed scroll, dynamic
Whirlpool disk, support frame, cross axle, the end cap and fixed scroll seal to form high pressure chest, and the shell is enclosed low with support frame
Press chamber；The fixed scroll end face offers gas vent, and the exhaust bore end is equipped with check valve, the check valve include baffle and
Elastic slice, the baffle and elastic slice are fixed on fixed scroll end face by fastening screw；The elastic slice bottom is equipped with the first magnet, institute
Fixed scroll end face is stated equipped with the second magnet, first magnet is magnetic opposite with the second magnet and is oppositely arranged.
Preferably, the fixed scroll end face be convexly equipped with step, the baffle and elastic slice be fixed on by fastening screw it is described
On step, the ledge surface opens up fluted, and second magnet is arranged in the groove.
Preferably, the second magnet quantity is two, is respectively arranged at gas vent two sides, the first magnetic on the elastic slice
Iron quantity is two, is oppositely arranged respectively with described two second magnet.
The beneficial effects of the utility model are: the magnet of elastic slice bottom attracts each other with fixed scroll Surface Magnet, to make
Elastic slice is fitted tightly over fixed scroll surface, effectively prevents the reflux of high pressure gas.Meanwhile when elastic slice is for a long time using generation
When deformation, the magnetic force that magnet generates can guarantee the compactness that elastic slice is bonded with fixed scroll surface, effectively prevent elastic slice because of shape
Become and influence sealing performance, structure is simple, at low cost.
Detailed description of the invention
Fig. 1 is the utility model scroll compressor structure schematic diagram；
Partial schematic diagram when Fig. 2 is the work of the utility model screw compressor；
Fig. 3 is partial schematic diagram when the utility model screw compressor stops working.
Description of symbols: shell 1, end cap 2, fixed scroll 3, movable orbiting scroll 4, support frame 5, cross 6, air inlet 7, exhaust

Specific embodiment
The utility model is further described below in conjunction with the drawings and specific embodiments, but present embodiment is simultaneously
It is not limited to content below, arbitrarily can change and implement in the range of the purport of lossless the utility model.
As shown in Figure 1, the utility model screw compressor includes shell 1, end cap 2, fixed scroll 3, movable orbiting scroll 4, support frame
5, cross 6, the shell 1 is assembled together with the end cap 2 by pin shaft, and is fastenedly connected by screw, 1 content of shell
It is equipped with fixed scroll 3, movable orbiting scroll 4, support frame 5, cross 6, shaft, hollow motor.
Described shaft one end is rotatably arranged on 2 bottom of shell by sliding bearing, and the rotor fixation of the hollow motor is set
It sets in shaft, stator is fixed at 1 inner sidewall of shell, and the shaft other end is equipped with support frame 5, and support frame as described above 5 is logical
It crosses rolling bearing and the shaft other end is rotatablely connected.Support frame as described above 5 is fixedly connected by pin with fixed scroll 3, described
It is equipped with movable orbiting scroll 4 in fixed scroll 3, the wrap tip face of the movable orbiting scroll 4 opens up fluted, and the groove internal clearance is equipped with sealing
Circle, sealing ring abut fixed scroll bottom surface, and the wrap tip face of the fixed scroll 3 opens up fluted, the groove internal clearance
Equipped with sealing ring, sealing ring abuts movable orbiting scroll bottom surface.
The side wall of the shell 1 offers air inlet 7, and the side wall of the end cap 2 offers gas outlet 8, the end cap 2 with
Fixed scroll 3 is fixedly connected by pin, is equipped with seal washer, end cap 2 and fixed scroll 3 at the end cap 2 and 3 joint face of fixed scroll
