Problems solved by technology
However, the scroll compressor has the following disadvantages: During the operation of the compressor, when the compressor is operated under the state of excessive compression due to other reasons or when the auxiliary (suction) valve is in the closed state for evacuation operation, due to remaining in the suction The medium gas in the space S2 is all sucked into the compression space and discharged into the discharge space S1, so the suction space S2 and the compression space of the body 1 gradually form a vacuum state; long-term vacuum compression will cause the sealing parts (not shown in the drawings) ) is damaged and the material of the sealing part is damaged due to thermalization, which will inevitably reduce the reliability of the compressor.

An apparatus for preventing high vacuum of low-pressure vortex-type compressor by returning part of compressed gas back to sucking space is disclosed. It is composed of high-pressure and low-pressure isolating plates, main frame, static vortex disk, movable vortex disk between main frame and static vortex disk, check valve and by-pass valve on said static vortex disk, and a linkage lever between said two valves.
Description
technical field [0001] The present invention relates to a scroll compressor device, and is especially suitable for preventing components from being damaged due to high vacuum of a low-pressure scroll compressor. Background technique [0002] At present, compressors can be divided into: reciprocating compressors, scroll compressors, centrifugal compressors and vane compressors. Among the above-mentioned compressors, a reciprocating compressor is a compressor that compresses suction gas by using a reciprocating motion of a piston; a scroll compressor, a centrifugal compressor, and a rotary compressor are compressors that compress suction gas by using a rotating body. Scroll compressors can be divided into: low-pressure scroll compressors and high-pressure scroll compressors. [0003] Fig. 1 is a sectional view of a scroll compressor of an embodiment of the prior art. The structure of the low-pressure scroll compressor includes an organic body 1, which is filled with engine o...
