Air outlet diaphragm device and corresponding air compression device

Abstract

The invention discloses an air outlet diaphragm device and a corresponding air compression device. The air outlet diaphragm device comprises an elastic metal diaphragm piece, the elastic metal diaphragm piece is narrow in the middle and wide in the two ends, a mounting hole is formed in the elastic metal diaphragm piece, air outlet grooves are formed in the upper side and the lower side of the elastic metal diaphragm piece, and notches are formed in the left side and the right side of the elastic metal diaphragm piece; and the air compression device comprises an air cylinder, a piston, a piston rod, a valve plate and an air outlet diaphragm device, the upper end of the piston rod is connected with the piston, a compression cavity is formed between the valve plate and the upper end of the piston, the air outlet diaphragm device is fixed to the valve plate and used for controlling opening and closing of an air outlet in the valve plate, the air outlet can communicate with the compressioncavity and an air outlet hole formed in the air cylinder, a piston ring is arranged on the outer side of the piston in a sleeving mode, symmetrical connectors are arranged at the two ends of the piston ring, and the two connectors can be buckled with each other after getting close to each other to enable the piston ring to form a sealing ring. The air outlet diaphragm device has the advantages that the working noise is reduced, the overall work is stable, the service life is long, and the air outlet effect is good.

Description

【Technical field】 [0001] The invention belongs to the technical field of air compression devices and parts thereof, and in particular relates to an air outlet diaphragm device and a corresponding air compression device. 【Background technique】 [0002] An air compressor is a device used to compress gas. An air compressor is similar in structure to a water pump. Most air compressors are of the reciprocating piston type. The current air compressors mainly include air compression devices, motors, boxes and other components. According to the number of air compressor cylinders, air compressors can be divided into single-cylinder air compressors, double-cylinder air compressors, three-cylinder air compressors and Four cylinder air compressor. [0003] The air compression device mainly includes cylinder, piston, piston rod, valve plate, air outlet diaphragm device and other components. The air outlet diaphragm device generally adopts a circular valve plate, and the air outlet diaph...

AI Technical Summary

Problems solved by technology

[0003] The air compression device mainly includes cylinder, piston, piston rod, valve plate, air outlet diaphragm device and other components. The air outlet diaphragm device generally adopts a circular valve plate, and the air outlet diaphragm device needs to be installed with elastic springs during installation. Difference

The air compressor device using this air outlet diaphragm device and the installation method of the air outlet diaphragm device has problems such as high working noise and short service life.
