ELECTRICAL DRIVE VALVE

PROBLEM TO BE SOLVED: To provide an electrical drive valve that can inhibit a malfunction as much as possible while expanding a range of use application of an electrical drive valve such as a motor valve and a solenoid valve.SOLUTION: In an electrical drive valve, a seal member 70 for sealing a boundary between a valve chamber 21 and a lifting drive part is held between a valve body 20 and a guide bushing 26 fixed to the valve body 20. A ceiling part 21a of the valve chamber 21 in the valve body 20 is provided with a penetration hole 21b into which a valve stem 25 is inserted and a fitting hole 21d to which the guide bushing 26 is fixed. The seal member 70 is disposed in a recess hole 21c provided between the penetration hole 21b and the fitting hole 21d while being externally provided to the valve stem 25.SELECTED DRAWING: Figure 2 【課題】電動弁や電磁弁等の電気的駆動弁の使用用途を拡大しつつ、動作不良を可及的に抑えることのできる電気的駆動弁を提供する。【解決手段】弁室２１と昇降駆動部との間をシールするシール部材７０が、弁本体２０と該弁本体２０に固定されたガイドブッシュ２６とによって挟持される。弁本体２０における弁室２１の天井部２１ａに、弁軸２５が挿通される通し穴２１ｂ及びガイドブッシュ２６が固定される嵌合穴２１ｄが設けられ、シール部材７０が、通し穴２１ｂと嵌合穴２１ｄとの間に設けられた凹穴２１ｃ内で弁軸２５に外装されて配在される。【選択図】図２
