The invention belongs to the technical field of compressors, and relates to a structure and layout of an air compressor pressure regulating valve. The air compressor pressure regulating valve comprises a pressure regulating valve body, a balance piston, a pressure regulating spring, a stop valve, a return spring, a barrel cover and the like. The air compressor pressure regulating valve is characterized in that the pressure regulating spring is arranged on the pressure regulating valve, and meanwhile, an adjusting screw rod and a limiting nut are specially configured, or the adjusting screw rod, a shifting spring seat, a limiting screw and other parts used for adjusting the pre-tightening force of the pressure regulating spring and a mechanism composed of the parts are configured. Therefore, the upper limit value of the output pressure of an exhaust passage of the pressure regulating valve can be conveniently and accurately regulated, so that the interval range of the working pressure of lower devices can be flexibly, conveniently and accurately regulated and controlled according to a use object, the adaptability of the pressure regulating valve to the air pressure of the different lower devices is effectively expanded, the air supply pressure interval value can be conveniently and accurately adjusted to ensure the consistency of product quality, and finally the purpose of effectively reducing the production cost of the air compressor pressure regulating valve is achieved.
Description
technical field [0001] The invention belongs to the technical field of compressors, and relates to the structure and layout of a pressure regulating valve of an air compressor, in particular to a device that can conveniently, quickly and accurately set the range of the working pressure range of a lower gas device Air compressor pressure regulator valve for quick and accurate adjustment of the value. Background technique [0002] The air compressor is a general-purpose fluid mechanical device with large volume, wide range and deep influence. The high-pressure air output by it is often stored in an air tank in advance, and then guided from the tank when the lower air-consuming device needs to use compressed air. to the target device. As we all know, the lower device will use different pressures output by the gas tank according to the different objects of use. For example, the common pressure range of nail guns during decoration is 0.7 to 1.0MPa, while the spray guns for paint...
