Description

Technical Field

[0001] The utility model relates to the technical field of air compressor accessories, and particularly relates to an air compressor valve with adjustable pressure. Background Technique

[0002] The pressure regulating valve for air compressors is mainly used for the automatic control of the output pressure of air compressors. That is, when the output pressure of the air compressor reaches the upper limit of the required pressure set by the user, the pressure regulating valve opens, and compressed air is discharged through the air outlet hole to control the working state of the air compressor, so that the air compressor runs no-load and is in a no-load unloading state. When the output pressure of the air compressor drops to the lower limit of the required pressure set by the user, the pressure regulating valve closes, and the compressed air in the air outlet hole and its related pipelines is discharged, and the air compressor resumes load operation and is in a full-load state. Such reciprocating cyclic actions are used to implement the automatic regulation and control of the operating state of the air compressor.

[0003] According to a new type of pressure regulating valve for air compressors (authorization publication number: CN217736385U) disclosed on the patent network, it is described that "the utility model relates to a new type of pressure regulating valve for air compressors, including a valve body, an air inlet hole, and an air outlet hole. Its characteristics are: the air inlet hole is located at the bottom surface of the valve body, the air outlet hole is located on the lower side wall of the valve body, a valve core is arranged in the valve body, the valve core is a cylindrical body, the bottom surface is closed, the upper end surface is open, the bottom surface of the valve core is opposite to the air inlet hole located at the bottom surface of the valve body, a spring is arranged in the valve core, the top of the spring abuts against the bottom surface of the pressure regulating nut arranged on the upper part of the valve body, the pressure regulating nut is screwed on the differential pressure regulating nut, the differential pressure regulating nut is screwed on the upper part of the valve body, and a hole penetrating up and down is opened in the middle of the pressure regulating nut. The advantages of the utility model are: it can not only adjust the upper limit pressure of the air compressor, but also adjust the lower limit pressure of the air compressor, that is, adjust the pressure difference, and can realize the precise control of the output pressure of the air compressor, ensuring the stable and efficient operation of the air compressor."

[0004] Regarding the above description, the applicant believes that there are the following problems:

[0005] During the use of this utility model, by rotating the differential pressure regulating nut clockwise or counterclockwise, the spring is stretched or compressed to achieve the effect of pressure adjustment.
