Definitions

  • a method of assembling a flow rate control valve wherein one end of the outer cylinder member is closed with the base member, and the support is provided in a circular hole arranged coaxially with the valve port provided in the base member.
  • the cylindrical portion arranged coaxially with the drive shaft provided in the member is press-fitted, and the press-fitting of the cylindrical portion is advanced until the other end of the outer tubular member hits the support member, and the other end of the outer tubular member is pushed.
  • a back pressure chamber that is partitioned from the valve chamber is formed on the outside of the base member by closing the support member, and the valve body or the drive shaft is arranged across the valve chamber and the back pressure chamber. It is characterized by doing.
  • the fitting portion 71e of the holder body 71B is fitted inside the upper end 20b of the outer tubular member 20. Since the outer diameter of the fitting portion 71e is the same as the inner diameter of the outer tubular member 20, the outer peripheral surface of the fitting portion 71e is formed so as to contact the inner circumferential surface of the outer tubular member 20. With this, when the cylindrical portion 72B is press-fitted into the circular hole 14 of the base member 10, the outer peripheral surface of the fitting portion 71e contacts the inner peripheral surface of the outer tubular member 20 to move in the vertical direction (press-fitting direction). invite. Therefore, it is possible to prevent the cylindrical portion 72B from being inclined and press-fitted into the circular hole 14.

Abstract

Le problème décrit par la présente invention est de fournir : une vanne de régulation de débit qui permet de réduire efficacement la pression différentielle appliquée à un élément de vanne dans une direction de mouvement sans contraintes sur la forme de l'élément de vanne ; et un procédé d'assemblage pour la vanne de régulation de débit. La solution selon l'invention porte sur une vanne de régulation de débit (1) dans laquelle une extrémité inférieure (20a) d'un élément de cylindre externe (20) est bouchée par un élément de base (10) et une extrémité supérieure (20b) de l'élément de cylindre externe (20) est bouchée par un corps de support (71) pour former une chambre de contre-pression (23) qui est séparée d'une chambre de vanne (13). Un arbre d'entraînement (64) est agencé pour s'étendre sur la chambre de vanne (13) et la chambre de contre-pression (23). Un passage (16) qui mène à une ouverture (15) de vanne et un trou d'équilibrage de pression (17) qui relie ledit passage (16) et la chambre de contre-pression (23) sont disposés dans l'élément de base (10).
