Abstract:
A latching solenoid gate valve comprising 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.
Abstract:
A rising stem valve with a magnetic actuator having an outer and an inner magnet assembly that are magnetically coupled to each other so that the inner and outer magnet assemblies rotate together and a ball screw that is connected to the rising stem valve and that converts rotary to reciprocal motion. The inner magnetic cartridge assembly and valve body comprise a sealed lower section that is completely sealed to the outside environment.
Abstract:
Embodiments of the present disclosure are directed toward a second pneumatic actuator (12) configured to couple to a gate valve (10), wherein the second pneumatic actuator (12) is configured to apply a supplemental force to a gate (22) of the gate valve (10), wherein the supplemental force supplements an actuating force of a first actuator (50) of the gate valve. The valve utilizes a pneumatic system to improve valve operation without increasing size of the actuator, thus enabling usage of the valve with large bores and high pressures while reducing amount of mechanical force or torque needed to open and close the valve. The valve allows an actuation system and the pneumatic system to combine to apply greater shearing force to the wireline with the gate, thus enabling shearing of the wireline in an easy manner.
Abstract:
Methods and apparatus for particle reduction in throttle gate valves used in substrate process chambers are provided herein. In some embodiments, a gate valve for use in a process chamber includes a body having an opening disposed therethrough from a first surface to an opposing second surface of the body; a pocket extending into the body from a sidewall of the opening; a gate movably disposed within the pocket between a closed position that seals the opening and an open position that reveals the opening and disposes the gate completely within the pocket; and a plurality of gas ports disposed in the gate valve configured to direct a gas flow into a portion of the gate valve fluidly coupled to the opening.
Abstract:
A method for providing material to a gasifier. The method comprises providing a feedstock. A flow of the feedstock is formed. The flow is then delivered to a gasifier such that it provides a substantially airtight seal to the gasifier.
Abstract:
A seed planter (20) and seed meter (28) for planting different seed varieties based on the location of the machine in a field. A movable gate (150, 250) switches between seed varieties. The gate in one embodiment has three positions; one position opening a first seed passage (128) to the meter and closing a second seed passage (130), a second position opening the second seed passage and closing the first seed passage and a third position closing both the first and second seed passages. Two other gate embodiments have only two positions, each position opening one seed passage and closing the other.
Abstract:
An actuating device or displacing a control device, such as a valve, gate valve or other control mechanism, in particular for use in oil or gas production systems, comprises a motor-gear unit (21) and a thread drive (22) which is operable by said motor-gear unit (21) and which comprises at least a threaded spindle (23) and a screw nut (24). The threaded spindle (23) is displaceable in an essentially axial direction so as to displace the control device (2) between a use position (7) and a non-use position (8, 9, 19, 20). To ensure a safe displacement into the non-use position in a simple way and independently of the pressure conditions prevailing between conveying medium and inner medium, the threaded spindle (23) is substantially axially displaceable beyond the use position (7) into a second non-use position (9). The invention also refers to a corresponding method for displacing the actuating device.
Abstract:
Embodiments of gate valves and methods of using same are provided herein. In some embodiments, a gate valve for use in a process chamber may include a body having an opening disposed therethrough from a first surface to an opposing second surface of the body; a pocket extending into the body from a sidewall of the opening; a gate movably disposed within the pocket between a closed position that seals the opening and an open position that reveals the opening and disposes the gate completely within the pocket; and a shutter configured to selectively seal the pocket when the gate is disposed in the open position. In some embodiments, one or more heaters may be coupled to at least one of the body or the shutter.
