Problems solved by technology

[0002] The scroll compressor is a constant pressure ratio compressor, which will generate a lot of power consumption when it is running under the compression condition. In the prior art, because its exhaust hole is fixed on the upper plate of the static scroll, it can only Optimize the design for a specific working condition, and when the tooling deviates from this design working condition, the efficiency will be greatly reduced

specific Embodiment 1

[0015] Specific embodiment one: the height direction upper region of the upper large-diameter guide cavity 5 is provided with a retaining ring 8, and a spring 9 is arranged between the retaining ring 8 and the upper guide part 42, and the force of the spring 9 acts on the stopper 4 to ensure that the stopper 4 The position in the non-overcompressed state is stable and reliable.

specific Embodiment 2

[0016] Specific embodiment 2. On the basis of specific embodiment 1, the upper surface of the exhaust hole 6 is covered with a first exhaust valve plate 10, and the end of the first exhaust valve plate 10 away from the exhaust hole 6 passes through the first exhaust valve plate 10. The fastener 11 and the first valve seat 12 are fixed on the corresponding upper surface of the block 4;

[0017] The lower end of the first fastener 11 passes through the corresponding end of the first valve seat 12 and the first exhaust valve plate 10 sequentially, and is then fixedly mounted on the corresponding positioning hole 43 of the upper guide portion 42 of the block 4 .

[0018] Its working principle is as follows: a stopper that can move up and down is set on the static scroll, so that the scroll can open upward when it is overcompressed, so as to achieve the effect of exhausting in advance and reducing the power consumption of compression.

Abstract

The invention provides a vortex with an active pressure relief structure, which enables the vortex to be opened upwards during overcompression to achieve the effects of exhausting in advance and reducing compression power consumption. The vortex with an active pressure relief structure comprises a static vortex body, a guide hole is formed in the center of an upper plate of the static vortex body,a lower stop part of a stop block is embedded in the guide hole, the upper guide part of the stop block is arranged in the upper large-diameter guide cavity, the upper guide part of the stop block ascends or descends in the linear direction of the upper large-diameter guide cavity, a through exhaust hole is formed in the radial center of the stop block, and the exhaust hole is communicated with the lower vortex cavity.

Description

technical field [0001] The invention relates to the technical field of compressor structures, in particular to a scroll with an active pressure relief structure. Background technique [0002] The scroll compressor is a constant pressure ratio compressor, which will generate a lot of power consumption when it is running under the compression condition. In the prior art, because its exhaust hole is fixed on the upper plate of the static scroll, it can only Optimizing the design for a specific working condition, and when the tooling deviates from this design working condition, the efficiency will be greatly reduced. Contents of the invention [0003] In view of the above problems, the present invention provides a scroll with an active pressure relief structure, which enables the scroll to open upward when overcompressed, so as to achieve early exhaust and reduce compression power consumption. [0004] The scroll with active pressure relief structure is characterized in that ...
