摘要： The present disclosure discloses a micro-flow valve control mechanism, which comprises an electromagnetic coil, a base, a ring seat, a moving plate and an elastic plate; wherein the elastic plate is positioned above the base, the ring seat and the moving plate are positioned between the base and the elastic plate, the moving plate is positioned at the inner side of the ring seat. In this scheme, the structure of valve air intake control is optimized, and the ring seat plays the guiding role in the lifting of the moving plate to a certain extent, which ensures that the moving plate will not deflect in the air intake process, so that the outer ring at the lower side of the moving plate can allow air to enter uniformly, thus ensuring the working stability of the electromagnetic valve.

摘要： A valve assembly for controlling fluid flow rate comprising a valve block, a valve, a sensor chip package, and a controller interface. The valve block having an upstream reservoir, a downstream reservoir, and a valve seat for communicating fluid from an upstream location to a downstream location. The valve having a moveable member. The sensor chip package having at least one sensor coupled with the valve. The controller interface is communicable coupled to a control unit, the valve, and the sensor chip package. The controller interface sends at least one parametric value provided by the sensor chip package to the control unit. The controller interface receives a control signal used to adjust valve stroke of the valve. The control signal of the valve is determined based on the at least one measured parametric value and at least one other parametric value provided by a fluid processing system.

摘要： In order to provide a piezo valve in which it is possible to accurately predict the remaining lifespan of a piezo actuator, there are provided a valve seat, a valve body that is able to move between a fully closed position in contact with the valve seat and a fully open position, a piezo actuator that drives the valve body, a drive circuit that receives an input signal, and outputs to the piezo actuator a corresponding drive voltage, and a leakage current detector that, when the drive circuit outputs a voltage equal to or greater than a maximum rated voltage that drives the valve body to the fully closed/open position, detects leakage current from the piezo actuator. When the leakage current is detected or in a state immediately prior to detection, a fluid is flowing between the valve seat and the valve body.

摘要： A pneumatic-hydraulic type control valve includes a cable attached to a fixed base, a valve base disposed in the fixed base, and a valve stem disposed in the valve base and driven by the cable to be opened. First and second oil guiding holes of the valve base communicate with each other when the valve stem is opened, and the first and second oil guiding holes of the valve base do not communicate with each other when the valve stem is closed. Further, the valve stem has a first stressed portion for bearing a fluid closing force and a second stressed portion for bearing a fluid opening force. The outer diameter of the first stressed portion is larger than that of the second stressed portion. Thus, the present invention achieves effects of simplifying structure and accurate actuation without affecting the sealing effect.

摘要： A negative pressure pipeline opening-and-closing device includes a blocking member and a buoyant member. The buoyant member comprises two floats and a connection rod connected to the two floats. The liquid reservoir is provided with a guide therein, and the guide confines the two floats, the blocking member and the liquid outlet port in the same vertical line. A limiting member is arranged between the two floats and is fixed to an inner wall of the liquid reservoir. A maximum distance between the limiting member and a top wall of a lower float of the two floats is smaller than a maximum distance between a top wall of an upper float of the two floats and a top wall of the liquid reservoir. The negative pressure pipeline opening-and-closing device can replace an existing electrically controlled valve. Therefore, the cost is reduced, the maintenance is convenient and service life is prolonged.

摘要： An electrically operated valve having excellent wear resistance while suppressing cost is provided. The electrically operated valve comprises a valve main body having a valve seat; a motor including a stator fixed to the valve main body and a rotor driven to rotate with respect to the stator, a planetary gear type deceleration mechanism configured to decelerate rotation of the rotor to transmit to an output gear, a valve member configured to be movable toward and away from the valve seat in an axial direction, and a feed screw mechanism configured to convert rotational movement of the output gear into movement of the valve member in the axial direction. The planetary gear type deceleration mechanism includes a sun gear coupled to the rotor, a planetary gear engaged with the sun gear, a carrier for rotatably supporting the planetary gear, an annular ring gear engaged with the planetary gear, and a sliding member abutting against an axial end of the sun gear. The output gear has a different number of teeth than the ring gear, and engages with the planetary gear, and the sliding member is made of a different material from the material of the sun gear.
