摘要： A valve (1) for fluids, preferably for gases, comprises an inlet passage (2); an outlet passage (3); a shutter (4) interposed between the inlet passage (2) and the outlet passage (3) and movable between an open position and a closed position; actuating means (26,27). The valve (1) also comprises actuating means (26,27) operatively active on the shutter (4), which comprises an electromagnet (26) and a ferromagnetic element (27) that is movable as a function of the field generated by the electromagnet (26) for displacing the shutter (4) along the movement direction (L). In particular, the actuating means comprises a tubular body (5) made of non-magnetic material in which the ferromagnetic body (27) is inserted.

摘要： Present disclosure describes a shot peening flow control valve for regulating flow of ferromagnetic media. The shot peening flow control valve comprising a body enclosing a passage for transferring the ferromagnetic media from a first end of the passage to a second end of the passage and at least one core set arranged between the first end and the second end. The at least one core set comprises at least one magnetic unit, and the at least one magnetic unit is operable to provide a magnetic field at the passage. The at least one magnetic unit may project or provide the magnetic field at the passage in order to regulate, control, or stop the flow of ferromagnetic media. Thus, the shot peening flow control valve facilitates effective control of the ferromagnetic media during the shot peeing process.

摘要： The present invention is directed to an electromagnetic actuation system for opening and closing pipe valves. The electromagnetic actuation systems utilizes one or more electromagnets surrounding one or more permanent magnets attached to a rotary shaft of the valve mechanism. A controller activates the one or more electromagnets such that the produced magnetic field rotates, thereby applying a force to the one or more permanent magnets and thus rotating the rotary shaft. The system does not require rotation of the one or more electromagnets relative to the one or more permanent magnets, advantageously reducing the number of moving parts within the valve system.

摘要： An expansion valve includes a housing, a threaded bush, a valve body, and a permanent magnet body. The threaded bush is arranged in the housing and extends along an axial direction. The threaded bush includes an external thread. The valve body is partially adjustably received in the threaded bush along the axial direction. The permanent magnet body is of a pot-shaped design and arranged in the housing. The permanent magnet body extends the threaded bush along the axial direction such that the valve body is partially received in a valve body receptacle surrounded by the permanent magnet body. The permanent magnet body surrounds a radially outside of the threaded bush in a common transition portion. In the transition portion, the permanent magnet body is firmly connected to the threaded bush via a latching connection.

摘要： Apparatus and associated methods relate to a valve having an actuator configured to translate a mass in a plane and a valve element located out of the first plane and configured to translate along a first linear axis. In an illustrative example, at least one of the mass and the valve element may include a magnetic source providing a persistent magnetic field and the other may include a non-magnetized, magnetically permeable mass. Reluctance-induced forces may, for example, translate the valve element towards the mass along the first linear axis when the mass is brought into register with a second linear axis. The first linear axis and the second linear axis may, for example, be colinear. Various embodiments may advantageously provide a valve requiring low energy input for operation.

摘要： There is provided electromagnetic actuator. The electromagnetic actuator comprises a mover, a tubular coil and a tubular coil holder. The mover has a magnet. The tubular coil holder holds the tubular coil. The tubular coil holder has a cylindrical inner space for receiving the mover. The tubular coil and the magnet are configured to cooperate with each other to generate a force to move the mover relative to the coil holder along an axial axis. The mover comprises a ferromagnetic element arranged to change an inductance of the tubular coil in dependency on a position of the mover relative to the tubular coil holder. Further, there is provided a valve for opening and closing a conduit. The valve comprises the electromagnetic actuator.

摘要： The present disclosure provides an explosion-proof valve core, an explosion-proof valve, and a box body gas tightness detection clamp, including an explosion-proof valve core, a valve body, and sealing rings. The waterproof gas-permeable explosion-proof valve core of the present disclosure timely discharges high-temperature and high-pressure in a box body, which prevents explosion or reduces damage caused by explosion. An inner sealing ring in the explosion-proof valve is fixed through an inner sealing ring groove, so that a problem of poor sealing caused by easy falling and displacement of the inner sealing ring is solved. A metal protective shell is disposed on an outer side of an explosion-proof valve spring, a problem that the spring is blocked by battery core jets to weaken pressure relief performance when working is solved. The present disclosure further provides the box body gas tightness detection clamp, which is simple to use and operate.
