  • Patent number: 11512993
    Abstract: A valve device is capable of precisely adjusting a flow rate variation with time, aging, or the like without using an external sensor or using as few external sensors as possible. The apparatus includes an adjusting actuator for adjusting the position of the operating member positioned at the open position, a communication unit for receiving adjustment information relating to the adjustment of the opening degree of the flow path by the valve element from the outside of the apparatus, and a control unit for adjusting the position of the operating member by driving the adjusting actuator based on the adjustment information.

  • Patent number: 11506290
    Abstract: A valve device is capable of precisely adjusting a flow rate variation due to aging, aging, etc. without using an external sensor. An adjusting actuator includes a piezoelectric element for adjusting the position of the operating member positioned at the open position, and the drive circuit of the adjusting actuator includes a detecting unit for detecting an electric signal related to the amount of strain generated in the piezoelectric element, and a control unit for controlling the adjusting actuator so that the opening degree of the flow path by the valve element becomes the target opening degree based on the electric signal related to the amount of strain of the piezoelectric element.

  • Patent number: 11506294
    Abstract: A valve body unit is configured to be disengaged from a stem by moving the stem and the valve body unit to a valve seat side in a state where a bonnet is separated from the valve seat, thereby pushing a replacement ring such that the replacement ring moves through the bonnet while decreasing in diameter and then drops down onto a ring dropping portion in the free state, then moving the stem, the valve body unit, and the replacement ring to an opposite side to the valve seat side such that a first surface comes into contact with a second surface and the ring dropping portion comes into contact with the replacement ring, and in this state, moving only the stem to the opposite side to the valve seat side such that the connection formed by a connecting mechanism between the stem connection portion and the stem is released.

  • Patent number: 9951882
    Abstract: Provided is a cap for a handwheel that opens and closes a valve, capable of being readily attached to the handwheel without requiring a large space around the handwheel. The cap has easily switchable two working modes: One is a co-rotation mode where the cap is capable of rotating with the handwheel and the other is an independent rotation mode where the cap is capable of rotating independently of the handwheel. The cap has an internal casing to be securely fitted to the handwheel; an external casing being rotatable around its axis and having the internal casing in an interior thereof; a clutch for connecting the external casing with the internal casing and for disconnecting the former from the latter; and a maintaining member for keeping the external casing rotatable independently of the internal casing when they are disconnected by the clutch.
