摘要： A material spreader which is suspended beneath an airborne helicopter and which includes a container for flowable materials such as seeds, fertilizers or chemicals. The container has a discharge opening formed in its lower end which has a vertically movable valve positioned therein. The valve is controlled by the pilot of the helicopter from within the cockpit of the helicopter so that the application rate of the material may be varied without the necessity of landing the helicopter.

摘要： Methods and systems for a butterfly valve including a shape memory alloy (SMA) tube trained for rotation are presently disclosed. The SMA tube has a ground end coupled to a housing and rotating end coupled to a plate. The SMA tube is configured to rotate in a first direction in response to a first temperature change of the SMA tube. When rotating in the first direction, the rotating end of the SMA tube rotates and deflects the plate to rotate in a direction that permits a medium to flow through the valve. The SMA tube is also configured to rotate in a second direction in response to a second temperature change of the SMA tube. When rotating in the second direction, the rotating end of the SMA tube rotates and deflects the plate to rotate in a direction that does not permits a medium to flow through the valve.

摘要： A valve for dosing and mixing two fluids includes two respective inlet ducts, a double chamber for controlling the flows, at least one actuator configured to regulate the flow rates of the two fluids to be mixed, an electronic control unit and a Brix degrees optical sensor, arranged on the mixing duct of the mixture of the two fluids and operatively connected to the electronic control unit. The optical sensor is configured to send a measurement and control signal to the electronic control unit to drive the actuator so as to proportionally control the flow rates of the two fluids and, therefore, regulate the mixing ratio of the two fluids.

摘要： A mounting structure of a solenoid valve for operation on a cylinder provided with an operation port, the solenoid valve being configured to control operation fluid to be supplied to the cylinder, includes a mounting block attached with the solenoid valve, and a mounting screw threadedly engaged with internal threads of the operation port to mount the mounting block on the cylinder. The mounting block includes an inlet passage for supplying the operation fluid to the solenoid valve, an outlet passage for flowing the operation fluid controlled by the solenoid valve, and a through hole through which the mounting screw is inserted and with which the outlet passage is communicated. The mounting screw includes an inner passage to communicate the operation port with the outlet passage. Seal members seal between an inner wall of the through hole and the mounting screw.

摘要： A valve device having a valve housing, through which passes a fluid channel, in which are formed a valve seat and a valve member which is accommodated such that it can be moved relative to the valve seat, having an electromechanical actuator for moving the valve member between at least two functional positions in order to influence a free cross-section of the fluid channel, and having a control device, which is designed for activating the actuator depending on a control signal and includes a delay circuit which, in the case of the valve being switched off, is designed for a time-delayed movement of the valve member into a switch-off position. The delay circuit includes an electrical energy store which, in the case of the valve being switched off, is designed for energy-independent movement of the valve member into the switch-off position.

摘要： A first thermal shield constituted by a material with a thermal conductivity of 20 W/(m·K) or less and a second thermal shield constituted by a space are disposed between a passage and a laminated piezoelectric actuator. Preferably, a third thermal shield with a thermal conductivity of 20 W/(m·K) or less is further disposed. Thereby, a flow control valve which can effectively intercept a transmission of heat using a simpler and compacter structure than a flow control valve according to a conventional technology so that the temperature of a laminated piezoelectric actuator does not exceed its heat-resistant temperature even when it is used for high-temperature process gas is provided.
