PROPORTION CONTROL GAS VALVE OF PRESSURE ADJUSTING TYPE

摘要

PURPOSE: A rotation force of a stepping motor is used to move a diaphragm sidewise, thereby adjusting gas pressure preventing noise by vibration. CONSTITUTION: A stepping motor(10) rotates a rotation shaft(11) forming a screw line. An adjusting nut(21) is connected to the rotation shaft to convert the rotation movement to a linear movement. An adjusting screw moves along the adjusting nut moving back and forth. A sliding guide(30) comprises a slide support(35) to move the adjusting screw back and forth. A gas adjuster(40) is connected to the sliding guide to determine gas discharging amount. The gas adjuster comprises a gas inlet and a gas outlet.
