CONTROL DEVICE OF FLUID CONTROL VALVE

To provide a control device of a fluid control valve, which can attain at least one of improvement in the responsiveness of opening control and reduction of a load to a seal member while considering a slide resistance change caused by the seal member.SOLUTION: In an aspect of the present disclosure, a control device of a fluid control valve comprises: the fluid control valve 1 having a valve seat 13, a valve element 14, and a motor part 3 adjusting an opening degree by driving the valve element 14, in which the valve seat 13 is provided with a rubber seal portion 13a for sealing between the valve element 14 and the valve seal 13; and a control part 21 controlling the fluid control valve 1. The control part 21 corrects the control amount of the motor part 3 in opening degrees within a rubber seal influence range, which is an opening range in which the valve element 14 slides on the rubber seal portion 13a when opening and closing the valve.SELECTED DRAWING: Figure 7 【課題】シール部材による摺動抵抗変動を加味して、開度制御の応答性の向上とシール部材への負荷の軽減の少なくとも一方を図ることができる流体制御弁の制御装置を提供する。【解決手段】本開示の一態様は、弁座１３と、弁体１４と、弁体１４を駆動させて開度を調整するモータ部３と、を有し、弁座１３に弁体１４と弁座１３との間を封止するゴムシール部１３ａが設けられた流体制御弁１と、流体制御弁１を制御する制御部２１と、を有する流体制御弁の制御装置において、制御部２１は、開閉弁時にて、弁体１４がゴムシール部１３ａに摺動する開度範囲であるゴムシール影響範囲内の開度では、モータ部３の制御量を補正する。【選択図】図７
