FLOW RATE CHARACTERISTIC ADJUSTMENT MECHANISM OF SOLENOID PROPORTIONAL VALVE AND FLOW RATE CHARACTERISTIC ADJUSTMENT METHOD USING THE SAME

摘要

After the flow characteristics of the product assembly to facilitate electronic proportioning valve that adjusts the flow characteristics of the electronic proportional valve to provide a flow rate adjustment mechanism and the characteristic adjustment method using the same, the coil 17 is wound in the third core 15 is securely fixed to the coil bobbin 16, a coil bobbin 16, the inlet passage (3) and the valve seat (6) is passed to connect the outlet passage (4), and the valve seat 12 to open and close the valve seat (6), and the valve seat 12 that is integrated with the plunger 10, the plunger (10 ), the valve seat (6) for biasing the direction plate spring 8, a first core 9 interposed between the coil bobbin 16 and the body (2) with a coil bobbin removably to 16 covered which has a hood 19, in the electronic proportional valve (1A) forming the magnetic circuit surrounding the periphery of the third core 15 and the first core (9) and the bonnet (19), the coil (17) , rotate the set screw (22) to move the hood (19) in the direction of the axis, changes the magnetic circuit.
