摘要： The present invention provides a pyrotechnic valve that can be recovered for reuse, which includes a ignitation assembly that is mounted to a stop ring assembly and a body assembly. The body assembly contains a piston assembly that plays the role of moving to cut off the interior tubing passageways of the elbow block when the ignition assembly works. The technical solution described in this invention provides a reliable and stable pyrotechnic valve design, providing a valve recovery solution that helps reduce the cost of testing.

摘要： Disclosed are an assembly for preventing clamping stagnation of a valve rod, and a valve structure and method for preventing clamping stagnation of a valve rod. The assembly for preventing clamping stagnation of a valve rod includes a rigid ring and an elastic ring. The rigid ring is coaxially sleeved in the elastic ring, and the inner wall of the rigid ring is of a straight cylindrical structure. A valve rod can move up and down along the inner wall of the rigid ring under the guidance of the rigid ring and forms a sliding pair together with the rigid ring. The joint between the rigid ring and the valve rod is closed. The assembly for preventing clamping stagnation of a valve rod is simple in structure, convenient to manufacture, and suitable for most valves having elongated valve rod structures.

摘要： In a semi-finished product for a valve housing, such as a control valve housing or a fitting housing, may include an additively manufactured body having a built-up direction in which the body is formed in layers. The body may include an inlet channel, an outlet channel, a bridge section, and a neck portion for the valve or the fitting delimiting a channel structure to be formed for process fluid. The body forms an inner surface to be directed towards a process fluid and an outer surface to be facing the surroundings. The inner or outer surface may have at least one overhang surface with respect to the built-up direction, the overhang angle of which does not exceed an angular threshold value of at most 75°.

摘要： A valve assembly including a valve housing and a handle that is movable about an actuation axis to actuate a valve actuator within the valve housing between an open position and a closed position. The handle has a first opening and the valve housing has a second opening. When the valve actuator is in the closed position the first opening aligns with the second opening to enable receipt of a lockout member that prevents movement of the valve actuator from the closed position to the open position.

摘要： A deaerator with integrated shut-off valve comprising a detachable hollow body having a lower part of a cup-shaped body having an inlet connectable to a hydraulic manifold, and an upper part of the cup-shaped body having a vent opening. The upper part is configured to be stabilized the lower part to define a deaeration chamber. The deaerator may include a float assembly having a float element and a drive mechanism. The deaerator may further include a shutter slidingly arranged through said inlet opening of said lower portion, and a head arranged on the inner end of the body. The shutter may include a collar to block the passage of liquid through the opening when the upper part is detached from the lower part of the same body.
