The invention relates to a novel miniature air valve which comprises a motor, a cylindrical pushing valve fixed on a motor output shaft, a cylindrical casing fixed on the motor and a guide sleeve located between the casing and the pushing valve. The pushing valve, the guide sleeve, the casing and the motor output shaft are coaxially arranged, protruding short columns are arranged on the circumferential surface of the pushing valve in the radial direction, the pushing valve is matched in a guide sleeve body, the short columns are connected on the end face of the guide sleeve facing the pushing valve in an overlapping mode, a spiral face is arranged on the end face of the guide sleeve facing the pushing valve, two column bodies arranged in the axial direction of the guide sleeve are evenly distributed on the circumferential surface of the guide sleeve, a round groove is formed in the casing along the axis, the guide sleeve is matched in the round groove, two sliding sleeves formed in the axial direction of the round groove are evenly distributed on the circumferential surface of the round groove, the two column bodies are matched in the two sliding grooves, a ventilation pipe penetrates the lower end of the round groove in the radial direction, and two ends of the ventilation pipe penetrate the casing. The novel miniature air valve is remarkable in effect, reliable in work, small in resistance loss, good in sealing performance and small in clearance volume, and the noise is greatly reduced.
Description
technical field [0001] The invention relates to a novel miniature air valve. Background technique [0002] The air valve is one of the most important and easily damaged parts in the compressor. Its quality directly affects the displacement, power consumption and operation reliability of the compressor. At present, some air valves work unreliably, have large resistance loss and high noise, which will make the air valve work unreliably, large resistance loss and high noise. Contents of the invention [0003] In order to solve the above problems, the present invention provides a new type of miniature air valve, which has reliable operation, small resistance loss, good sealing performance, small clearance volume and greatly reduced noise. [0004] To achieve the above object, the specific scheme of the present invention is: [0005] A new type of miniature air valve, including a motor, a cylindrical push valve fixed to the output shaft of the motor, a cylindrical shell fixed...
