摘要： A valve device includes a housing, a stationary disk, a drive device, a shaft and a rotor. The stationary disk is fixed at an inside of the housing and has at least one flow passage hole. The shaft is rotated about a central axis by the drive device. The rotor increases or decreases an opening degree of the at least one flow passage hole. The rotor includes: a drive disk that slides relative to the stationary disk; and a lever that is fixed to the drive disk and couples between the drive disk and the shaft. A torsion spring is placed between the shaft and the lever and urges the lever relative to the shaft in a circumferential direction around the central axis of the shaft. The shaft has a plurality of contact portions configured to contact the lever and respectively located at a plurality of locations.

摘要： A gate valve and method according to which a gate body extends within a valve cavity, a fluid bore extends through the gate body, and a passage extends from the fluid bore, through the gate body, and to the valve cavity. The valve cavity is pressurized with a lubricant to prevent, or at least resist, solid particles (e.g., sand, fines, debris, etc.) from entering the valve cavity. The valve cavity and the fluid bore are pressure balanced. In some embodiments, a flow valve, such as a check valve or one-way valve, is positioned within the passage.

摘要： A gate valve includes a valve base, a first piston unit disposed in the valve base and driven by a fluid to move the valve door between a first position where the valve port is opened and a second position where the valve port is covered, a second piston unit disposed in the valve base and driven by the fluid to move the valve door between the second position and a third position where the valve port is sealed, and a valve door fitted to a valve port of the valve base. At least one flow channel switch is disposed in the valve base. When the flow channel switch is turned on, the fluid is allowed to pass through, such that the second piston unit drives accurately the valve door to seal the valve port, thereby achieving purposes of enhancing accuracy in operation and ensuing airproof performance.

摘要： A valve including a valve seat assembly that includes a first valve seat sealing member positioned between a first valve seat retaining ring and a first radially inwardly extending flange that extends from an inner surface of a hollow valve retainer, and a second valve seat sealing member positioned between a second valve seat retaining ring and a second radially inwardly extending flange that extends from the inner surface of the hollow valve retainer. A valve member is configured to engage and disengage with the first and second valve seat sealing members to permit fluid to travel from a fluid inlet to a fluid outlet.

摘要： The present disclosure provides a modular linear actuated valve having a lower body module that can interface with an interchangeable upper linear actuator module being at least one of a mechanical linear actuator module and a fluid linear actuator module. The invention includes a quick disconnect between the body module and any of the actuator modules. An actuator assembly on the selected actuator module can be coupled to the valve stem on the lower body module using a quick disconnect segment on the actuator module and a reciprocal quick disconnect segment on the body module. A valve can be quickly converted into a mechanical linear actuated valve or a fluid linear actuator valve, simplifying manufacturing and stocking, and providing a faster response to customer orders.

摘要： A method of opening a fluid control valve having a housing externally fitted onto a fluid pipe in a hermetic state and a valve body configured for contacting an inner peripheral surface of a hole of the fluid pipe provided in the housing and an inner peripheral surface of the fluid pipe to hermetically block or open flow of fluid in the fluid pipe. The method includes a pressure adjustment step of decreasing a pressure difference between the fluid in the fluid pipe on a first side and a second side of the valve body and the fluid in the fluid pipe in a blocking state of the valve body. The first side and the second side of the valve body are arranged so as to sandwich the valve body in an axial direction of the fluid pipe, and a valve opening step of opening the valve body.

摘要： A passage switching device to switch flow passages includes a rotary disk and a fixed disk which are stacked in an axial direction. The rotary disk is provided with at least one rotary disk communication path penetrating in the axial direction, and the fixed disk is provided with a plurality of fixed disk communication paths penetrating in the axial direction. The flow passages are switched by rotating and driving the rotary disk to switch combination of the rotary disk communication path and the fixed disk communication path for communication. There is provided an elastic member between the housing and the rotary disk, between the rotary disk and the fixed disk, and between the fixed disk and the housing with respect to the axial direction.
