Embodiment Construction

[0029] Such as Figure 1 to Figure 6 As shown, it is a one-way valve with noise reduction function applied to scroll compressors according to the present invention. The one-way valve includes a valve mounting seat 1, a metal circular valve seat 2 and a metal circular valve plate 3, and the metal circular valve The center of the sheet 3 is provided with a through hole 23, the diameter of the through hole 23 is smaller than the diameter of the cover 7, and the metal circular valve sheet 3 matches the metal circular valve seat 2, the design of the through hole 23 can facilitate the gas from the metal The through hole 23 of the circular valve plate 3 flows out, and then flows out from the air flow channel. The diameter of the through hole 23 is less than the diameter of the retaining cover 7, so that when the metal circular valve plate 3 is closed, it is ensured that the retaining cover 7 closes the metal circular valve. The through hole 23 of the valve plate 3 is blocked, so that...

Abstract

The invention discloses a noise reduction check valve applied to a scroll compressor. The noise reduction check valve comprises a valve mounting base, a metallic round valve seat and a metallic round valve block, and further comprises a perforated-plate exhaust seat and a noise reduction guide sleeve, wherein the metallic round valve seat comprises a valve seat body and a cover; the perforated-plate exhaust seat comprises a fixed framework and noise reduction baffles; the noise reduction guide sleeve comprises a housing, noise reduction plates, a flow guide shade and a noise reduction cylinder; the housing comprises an inner housing and an outer housing; silencer cotton is arranged in a cavity between the inner housing and the outer housing; and the noise reduction plates, the flow guide shade and the noise reduction cylinder are all located in the housing. The noise reduction check valve is simple in structure and high in practicability; as the perforated-plate exhaust seat is arranged in the check valve, the check valve and a noise reduction cavity are combined, accordingly, noise generated by air impact is effectively reduced, the noise reduction effect of the scroll compressor is remarkably improved, and the scroll compressor can be used more safely and stably; and meanwhile, as the noise reduction guide sleeve is added, the noise reduction effect of the check valve is further improved, and the comprehensive utilization ratio is also improved.

Description

technical field [0001] The invention relates to a one-way valve with sound-absorbing function applied to a scroll compressor. Background technique [0002] In recent years, scroll compressors have attracted attention because of their high efficiency, low noise, and balanced operation. The scroll compressor is a volumetric compression compressor, and the compression part is composed of an orbiting scroll and a fixed scroll. The unique design of the scroll compressor makes it an energy-saving compressor in the world today. Scroll compressors run smoothly, with low vibration and quiet working environment, and are also known as "ultra-quiet compressors". They are widely used in industries such as industry, agriculture, transportation, medical equipment, food decoration, textiles, and other industries that require compressed gas media. occasions. The scroll compressor is composed of two double-function equation-shaped moving and static scrolls meshing with each other. During ...
