Problems solved by technology

[0002] In the related technology, the exhaust structure of the compressor is mainly a straight-through design. During the exhaust process, when the airflow enters the exhaust hole, the airflow is separated on the surface layer of the exhaust hole, causing vortex phenomenon, and the exhaust local resistance increases. , resulting in a decrease in the effective exhaust flow area and an increase in the power consumption of the compressor; when the airflow leaves the exhaust hole, the airflow velocity is high, the pressure is low, and the exhaust resistance is large, which also increases the power consumption of the compressor and the noise

Abstract

The invention discloses an exhaust valve seat and a compressor. The exhaust valve seat comprises a valve seat body, the valve seat body is provided with an exhaust hole, the exhaust hole is sequentially provided with a necking part, a transition part and a flaring part in the exhaust direction, and in the exhaust direction, the cross sectional area of the necking part is decreased progressively, and the cross sectional area of the flaring part is increased progressively. The inner wall of the necking part and the inner wall of the flaring part are respectively connected with the inner wall of the transition part; and the axial height of the necking part is H1, the axial height of the transition part is H2, the axial height of the flaring part is H3, and (H1+H2) / (H1+H2+H3) is larger than or equal to 0.2 and smaller than or equal to 0.8. According to the exhaust valve seat, the gas vortex phenomenon at an inlet and an outlet of an exhaust hole can be reduced, the exhaust resistance is reduced, the power consumption of the compressor is reduced, and the energy efficiency of the compressor is effectively improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an exhaust valve seat and a compressor. Background technique [0002] In the related technology, the exhaust structure of the compressor is mainly a straight-through design. During the exhaust process, when the airflow enters the exhaust hole, the airflow is separated on the surface layer of the exhaust hole, causing vortex phenomenon, and the exhaust local resistance increases. , resulting in a decrease in the effective exhaust flow area and an increase in the power consumption of the compressor; when the airflow leaves the exhaust hole, the airflow velocity is high, the pressure is low, and the exhaust resistance is large, which also increases the power consumption of the compressor and the noise . Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present inven...
