Scroll compressor with new exhaust port structure and exhaust valve assembly

Abstract

The invention discloses a scroll compressor with a novel exhaust port structure and an exhaust valve component. The scroll compressor comprises a shell, an air inlet pipe, an air outlet pipe, a motor, a rotor shaft component and a scroll plate component, wherein an exhaust port is formed in the scroll plate component; a groove is formed in the upper surface of the scroll plate component positioned at the periphery of the exhaust port; the groove is formed towards the bottom of the exhaust port; a valve plate which covers the exhaust port and is in a long strip type is laid in the groove; one end of the valve plate is fixedly connected with the upper surface of the scroll plate component; a limiting plate with an arc-shaped lower surface is arranged on the valve plate; and when the exhaust port starts and stops exhausting air, the other end of the valve plate swings up and down between the upper surface of the scroll plate component and the arc-shaped lower surface. According to the scroll compressor, the exhaust port structure and the exhaust valve component are optimized, and the clearance volume is reduced to the greatest degree, so that at high compression ratio, the operating efficiency of the compressor is improved, the shutdown response speed of the compressor is increased, and the manufacturing cost and the using cost are reduced.

Description

technical field [0001] The invention relates to a scroll compressor, in particular to a scroll compressor with a novel exhaust port structure and an exhaust valve assembly. Background technique [0002] Refrigeration scroll compressors are widely used in various industries of national life. With the development of economy and technology, ordinary scroll compressors are not only used in the refrigeration and air-conditioning industry, but also more and more widely used in low-temperature refrigeration, heat pump water heaters and other industries. Low-temperature refrigeration and heat pump water heaters often have a wider application range and higher compression ratio application characteristics, which put forward higher requirements for the safety, stability and operating efficiency of the compressor. In industries such as cryogenic refrigeration and heat pump hot water, there may be a higher compression ratio, and in some applications, the scroll compression ratio even re...

Problems solved by technology

However, the addition of the valve seat increases the distance from the valve plate to the bottom of the exhaust port under the same wall thickness of the scroll disc exhaust port, which increases the clearance volume of the exhaust port to a certain extent, which has a great impact on compression The operating efficiency of the machine at high compression ratio and the response speed of shutting down still form unfavorable factors, and its structure is more complicated, and the manufacturing and use costs are higher
