Claims (1)
連結し得る出力軸２を枢支し、ハンドル３或いは
モータの回転により一方向にのみ回転する歯車４
に外周歯５１……５１が噛合して出力軸２とは無
関係に回転するインターナルギヤ５を同出力軸に
枢支し、同インターナルギヤの内周歯５２……５
２と、出力軸２に固着された歯車６の外周歯に共
に噛合する歯車７を軸７１にて枢支した歯車８を
出力軸２に同出力軸と無関係に回転するように枢
支し、出力軸２には同力軸のバルブ開放方向への
回転により巻かれるゼンマイバネ９を設けると共
に、通電時には前記歯車８の回転を阻止し、通電
遮断時には同歯車８の回転を許容する電磁装置１
０を設けて成るバルブの緊急閉鎖装置。 In the casing 1, an output shaft 2 which can be connected to the rotating shaft of the valve body of the valve A is pivotally supported, and a gear 4 rotates in only one direction by the rotation of a handle 3 or a motor.
An internal gear 5, which rotates independently of the output shaft 2 with outer peripheral teeth 5 1 ... 5 1 meshing with the output shaft 2, is pivotally supported on the output shaft, and inner peripheral teeth 5 2 ... 5 of the internal gear are rotated independently of the output shaft 2.
2 , and a gear 8 which is pivoted by a shaft 71 to a gear 7 that meshes with the outer peripheral teeth of a gear 6 fixed to the output shaft 2, is pivoted to the output shaft 2 so as to rotate independently of the output shaft. An electromagnetic device 1 is provided on the output shaft 2 with a spiral spring 9 that is wound by the rotation of the force shaft in the valve opening direction, and that prevents the gear 8 from rotating when energized and allows the gear 8 to rotate when the energization is interrupted.
An emergency closing device for a valve comprising: 0.
