    摘要： In a valve device, a rotor includes a drive disk and a lever fixed to the drive disk. The lever couples between the drive disk and a shaft. In the valve device, a first torsion spring is placed between a housing and the shaft, and a second torsion spring is placed between the shaft and the lever. A drive device includes an electric motor configured to drive the shaft in a rotational drive range, which is between an initial rotational position and a maximum rotational position, in a first rotational direction toward the initial rotational position and a second rotational direction opposite to the first rotational direction. The first torsion spring urges the shaft relative to the housing in the second rotational direction in the state where the shaft is placed in the initial rotational position upon the rotation of the shaft in the first rotational direction.

    摘要： A gate valve of the invention includes a valve box, a neutral valve body, and a rotation shaft. The neutral valve body includes a neutral valve and a movable valve. The movable valve includes a first movable valve and a second movable valve. The gate valve includes a plurality of first force-applying units, a second force-applying unit, and a third force-applying unit. The third force-applying unit applies a force to the first movable valve. The first force-applying units apply a force to the first movable valve and thereby causing the seal portion to be in close contact with a valve box inner surface located at a periphery of the first opening portion. The second force-applying unit drives the first movable valve and the second movable valve so that thicknesses thereof in the flow passage direction are adjustable.

    摘要： A blind assembly for use in a piping circuit that includes a blind element and an injection system. The blind element has a planar portion that is transversely mounted in the piping circuit to block flow through the piping circuit. When the blind element is installed, it has one or more flat surfaces that are in sealing contact with another component of the piping circuit, such as a flange face, to define a sealing interface. A primary seal is provided between the blind element and the other component of the piping circuit and which circumscribes at least a portion of the sealing interface. The injection system is in communication with the sealing interface, and selectively injects a sealant material into the sealing interface to form a redundant seal in the sealing interface and around the primary seal. An injection fitting can mount to the flange for injecting the sealant.

    摘要： A vacuum control valve connected between a vacuum chamber and a vacuum pump includes a control valve main body having a valve seat formed in a vacuum flow passage, a valve body that manipulates the valve opening by performing a linear motion to adjust a lift, a rod that transmits driving force from a linear driving unit that generates the driving force, a sliding/sealing member that seals the vacuum flow passage while allowing the rod to slide, and a cylindrical member that covers a sliding range of the rod. The sliding range includes a range movable from a valve body flow passage side to an exterior side. The cylindrical member has an outer peripheral surface, a working fluid absorption amount per unit area of the outer peripheral surface being smaller than that of an outer surface of the rod.
