摘要： A latching solenoid gate valve is disclosed, and includes a housing defining a conduit having a flow path therethrough and a cavity separating the conduit into a first section and a second section. The latching solenoid assembly also includes a gate assembly enclosed within the cavity of the housing and a first solenoid assembly and a second solenoid assembly seated within the cavity with the gate assembly linearly translatable therebetween. The gate assembly includes a first gate member comprising magnetizable material and defining an opening therethrough. The first gate member is linearly movable within the cavity between an open position with the opening aligned with the conduit and a closed position with the opening out of alignment with the conduit. The first gate member is moved linearly from either the open position or the closed position.

摘要： A self-holding electromagnetic valve includes: a solenoid having a tubular guide part having the same center as a central axis extending in an axial direction; a axially movable element located radially inside the guide part; a cover housing the solenoid and the movable element, having a hole portion, and made of a magnetic material; a pin located at the hole portion and movable along with movement of the movable element; and a valve section provided outside the cover and opened/closed along with movement of the movable element and the pin. The solenoid has a cylindrical part with an inner circumferential surface that receives the guide part, tooth parts that extend radially outward from the cylindrical part and are made of a magnetic material, bobbin parts provided each tooth part, and coils wound around the bobbin parts.

摘要： A valve apparatus comprises a housing, a solenoid operable to receive electrical current flow, and an enclosure, the enclosure housing the solenoid, a magnet coupled to the enclosure, a plunger comprising a stopper and a conductive portion, and a spring coupled to the plunger. When the solenoid receives a first current, the solenoid applies a first magnetic force onto the plunger causing the stopper to disengage from the housing outlet, the conductive portion of the plunger magnetically connects with the magnet, and the stopper remains disengaged from the housing outlet after the first period of time expires. When the conductive portion is magnetically connected to the magnet and the solenoid receives a second current, the solenoid applies a second magnetic force onto the plunger causing the conductive portion of the plunger to disconnect from the magnet so that the stopper engages with the housing outlet.

摘要： A valve system has a main body including a valve element that controls flow of fluid between a plurality of ports and an operation unit capable of being detachably attached to the main body. The main body includes: a driving element that is operated from the outside by a magnetic force and directly or indirectly drives the valve element; and a first housing that houses the valve element and the driving element and is watertight in a state where pipes are connected to the plurality of ports. The operation unit includes: an operation element that generates a magnetic field that operates the driving element; and a second housing that houses the operation element, when attached to the first housing, the operation element and the driving element being in a facing state via part of a wall of the first housing and part of a wall of the second housing.

摘要： The present invention discloses a device for flow control of fluid in pipelines to various utility fluid outlets like water taps and the like by blocking fluid flow from pipeline to said utility fluid outlet when the flow exceeds a predetermined flow rate. In other word, the present invention discloses an automatic fluid flow controlling device for restricting and/or stopping flow of the fluid medium miming through the guiding means or the tubing system when fluid flow exceed a certain flow rate as well as stopping flow of the running fluid flow when fluid level in the vessel wherein the running fluid is being delivered reaches a certain height.

摘要： The present invention, in part, relates to methods and apparatuses for on-chip amplification and/or detection of various targets, including biological targets and any amplifiable targets. In some examples, the microculture apparatus includes a single-use, normally-closed fluidic valve that is initially maintained in the closed position by a valve element bonded to an adhesive coating. The valve is opened using a magnetic force. The valve element includes a magnetic material or metal. Such apparatuses and methods are useful for in-field or real-time detection of targets, especially in limited resource settings.

摘要： A valve device includes a valve having an electrodynamic actuator. The electrodynamic actuator includes a movably mounted control element having a coil and a magnet arrangement immovable relative to the coil. A driving force caused by energization of the coil and transmitted to the control element substantially is linearly dependent on the current intensity. A front-end electronic unit is connected with the coil and includes a capacitor connected in parallel to the coil. A method for controlling a valve as mentioned above provides that, upon actuation of the electrodynamic actuator, during energization of the coil by a voltage source, a capacitor connected in parallel to the coil is charged. After termination of the energization by the voltage source, the coil is energized further by a discharge of the capacitor.

摘要： Two-way pressure relief valves featuring dual poppets and magnets that allow very rapid flow. Such flow is accomplished by a valve housing enclosing a hollow interior portion containing a stationary member including a magnet and a first pressure-movable poppet disposed in sealing arrangement with the housing and including a second magnet. To provide flow in the other direction, a second moveable poppet disposed coaxially and in sealing arrangement with the first poppet and is coupled to a spring that extends from a first end of the second poppet to a support structure coupled to the second magnet.

摘要： A relief valve can include a valve body, a valve member, a valve stem, and a magnetic member. The valve body can define a flow path that extends between a first port and a second port. The valve body can include a valve seat disposed between the first port and the second port. The valve member can be disposed between the valve seat and the second port of the valve body. The valve member can move along an actuation axis. The valve stem can be coupled to the valve member. The valve stem can extend from the valve member towards the first port. The magnetic member can be coupled to the valve member and can generate a magnetic force that urges the valve member to seal with the valve seat of the valve body.
