How to choose a compressor air valve
Thread Content
Gentle experts, the poster has a design task that involves pressurizing atmospheric oxygen to 150 atmospheres, with a nominal flow rate of 10 L/min; this is to be achieved through 4 stages of compression, resulting in a miniature, high-pressure compressor. When a double-acting cylinder is used, intake and exhaust valves must be installed on the cylinder section on the piston rod side. Due to the very small cylinder diameter of 30 mm, there is almost no space for installing valves along the cylinder’s axis; therefore, I plan to drill holes in the outer wall of the cylinder and arrange the valves radially along it. The diameters of the commonly used ring-shaped and hole-type valves are too large; I hope everyone can recommend some tubular intake and exhaust valves (similar to ordinary check valves) in order to reduce the diameter of the valves and facilitate installation. Thank you so much!
Finding a professional air valve manufacturer is not a problem.
Could you recommend some well-known valve manufacturers? Domestic or foreign, either works
If the cylinder diameter is too small, a concentric valve will suffice. There’s no need to make radial openings; otherwise the clearance will be excessive, which could result in a significant reduction in airflow.
This one is of the high-pressure type; the cylinder diameter is 30, and the piston rod is likely 20 in length. When the air valve hole is opened, the clearance becomes large, resulting in less air flow. It would be better to make it a single-acting design on the cover side, with a balanced section on the shaft side.
