摘要： The disclosed microfluidic valves may include a valve body having at least one cavity therein, a gate transmission element separating the cavity into an input gate terminal and an output gate terminal, a gate port configured to convey drive fluid into the input gate terminal, and a fluid channel. The gate transmission element may include a flexible membrane and a plunger coupled to the flexible membrane. The gate transmission element may be configured to move within the cavity to inhibit a subject fluid flow from an inlet port to an outlet port of the fluid channel upon pressurization of the input gate terminal, and to allow subject fluid flow from the inlet port to the outlet port upon depressurization of the input gate terminal. Various other related systems and methods are also disclosed.

摘要： Actuators for fluid catalytic cracking unit slide valves and similar valves are disclosed. The actuator frame is assembled by bolting, allowing for standardized configurations that permit stocking of parts and avoids prior art problems of dealing with actuators designed for each individual project, allowing for rapid assembly of new actuators on demand that suit each project by varying the incorporated components, as well as permitting for more-rapid servicing when necessary. Additionally, the instrumentation for the actuator is contained within the actuator frame, better protecting the instrumentation from damage such as from being struck. The actuator includes a new manual engagement system, providing for better engagement of manual controls to actuate the actuator and the accompanying valve when necessary.

摘要： High pressure loop exhaust gas circulation is achieved in an exhaust system (10) of an engine (12) by providing an adjustable valve (100) in an exhaust passage (18) of the engine (12). The valve (100) is configured to control fluid flow through the passage (18) and generate pressure to drive the high pressure exhaust gas recirculation. The valve (100) includes a valve inner surface (110) that has a curvilinear profile when viewed in longitudinal cross section. An actuator (140) is connected to the valve (100), and is configured to move the valve (100) relative to the exhaust passage (18) so as to control exhaust gas pressure within the exhaust passage (18). In some embodiments, a pilot tube (280) is used in combination with the valve (100) to generate high pressure exhaust gas recirculation at the engine (12) intake.

摘要： A limit switch for a rising-stem type valve which has a spring-loaded actuator arm with a bracket on one end which wraps around the valve stem. A follower or roller on the end of the bracket opposite the actuator arm rides on the rising stem of the valve, held in contact with the stem by the spring. When the stem has risen to a preselected position, usually the position in which the valve is fully open, the follower or roller engages a circumferential groove formed around the stem. This causes the spring to bias the actuator arm to move a tab at the opposite end of the actuator arm, and the tab operates a limit switch.

摘要： The invention concerns an operator assembly having a tubular housing extending along a central axis (X1) and a transmission mechanism arranged in an inner bore of the housing and extending along the central axis (X1). The transmission mechanism providing a screw with a threaded outer surface and a nut with a threaded inner surface. The nut is radially mounted around the screw and the inner thread is configured to cooperate with outer thread. The operator assembly further provides angular contact bearings that are radially arranged between the inner bore of the housing and an outer surface of the rotating nut to support in rotation and guide the nut within the housing. The angular contact bearings are axially adjacent and are disposed within an angular contact ball bearing and an angular contact roller bearing.

摘要： A valve manifold has a housing with a central mixing chamber and a shell surface. The shell surface of the valve manifold has at least two valve ports, with each valve port being associated with one valve. A first valve port has three openings, and additional valve ports each having three openings. A respective first opening of the valve ports is in direct fluid communication with the central mixing chamber, and the second and third openings of the valve ports are each in fluid communication with an inflow or outflow via a duct. A bottom of the mixing chamber, in relation to a plane arranged perpendicularly to a vertical longitudinal axis of the housing, has a slope towards the first opening of the first.

摘要： A gate valve with secure sealing mechanism includes a main body having a valve opening, a driver disposed on the main body, a sliding seat slidingly disposed in the main body, a swing arm, and a valve member. Therein, two ends of the swing arm are connected to the driver and the sliding seat, respectively, whereby the driver drives the swing arm to move circularly between a first and second position, thereby triggering the sliding seat to slide. When the swing arm is at the first or second position, the swing arm is biased against the route direction of the sliding seat. The valve member is disposed on the sliding seat for moving in parallel or vertical to the valve opening, thereby preventing the sliding seat from swaying when the swing arm is at the first or second locking position.
