SMC IRV10/20 series vacuum regulator

SMC IRV10/20 series vacuum regulator

Product Overview

Brand and positioning: The IRV10/20 series vacuum regulator launched by SMC is positioned as a precise pressure control equipment for industrial vacuum systems, with three major advantages of high flow rate, lightweight, and flexible installation. It is suitable for vacuum adsorption, leak testing, and other scenarios. It is an upgraded version of the previous generation IRV1000/2000 series, with a weight reduction of 20% and a flow rate increase of over 2 times.

Working principle and structural design

Working Principle:

Pressure regulation: Rotate the knob clockwise, adjust the spring to push the diaphragm and valve, connect the VAC side (vacuum pump) and SET side (load), and increase the vacuum degree on the SET side; The pressure on the SET side is transmitted to the vacuum chamber through the airway and balanced with the spring force to achieve pressure stability.

Pressure compensation: When the vacuum degree on the SET side is higher than the set value, the diaphragm moves upward, the valve closes, and the atmospheric suction valve opens to supplement the atmosphere and reduce the vacuum degree; When the vacuum degree on the SET side is lower than the set value, the diaphragm moves down, the atmospheric suction valve closes, and the valve opens to increase the vacuum degree.

Structural design:

Core components: knob (with locking function, press the hidden orange ring to lock), regulating spring, atmospheric suction valve, vacuum chamber, diaphragm, valve stem, valve.

Fixed method: The pressure gauge/digital pressure switch is fixed with a clip buckle. When disassembling, the clip must be removed first, and pressure operation is prohibited; The quick change connector is designed in a cartridge style and secured with a clip. To replace it, a Phillips screwdriver is needed to remove the clip.

Protective design: Airway aperture ø 2.6mm to avoid blockage; The side air intake holes of the fuselage need to be kept unobstructed, otherwise the pressure cannot be adjusted normally.
