Air compressor intake valve selection

For the selection of the air compressor intake valve, it is necessary to start from the description of the principle of the air compressor, and then make a selection based on the needs of the own factory through a series of corresponding problems. Please see the introduction below for details.

Air compressor introduction:

The intake capacity regulating valve (hereinafter referred to as the intake valve) is the core component of the air volume adjustment of the screw air compressor (hereinafter referred to as the screw air compressor), and is particularly critical in the accessories of the screw air compressor. Since the screw air compressor implements unattended operation, the reliability of the intake valve has become the first choice for screw air compressor manufacturers. Since the author has been engaged in the design of screw compressors in SULLAIR Asia Compressor Company for many years, he has the opportunity to contact the air intake capacity regulating valve of AIR-CON Company, which is currently used by the American Screw Air Compressor Company. This valve has been used in the screw air compressor market in the United States for more than 40 years. The reliability of the product is extremely stable, and there are no wearing parts. It has a number of international patents, so it is widely used in the American market such as the United States, Canada, and the Asian market. .

one. Structure introduction

The intake valve is composed of intake valve body, vent valve, pressure regulator (also called capacity regulating valve), solenoid valve and pipeline accessories. The main function is to adjust the intake air volume of the compressor under the action of the control system to make it match the The user's gas consumption remains an economical match. The valve can be used with both twin screw and single screw. The structure and characteristics of each part are introduced as follows:
