摘要： Apparatuses for controlling gas flow are important components for delivering process gases for semiconductor fabrication. These apparatuses for controlling gas flow frequently rely on flow restrictors which can provide a known flow impedance of the process gas. In one embodiment, a flow restrictor is disclosed, the flow restrictor constructed of a plurality of layers, one or more of the layers having a flow passage therein that extends from a first aperture at a first end of the flow restrictor to a second aperture at a second end of the flow restrictor.

摘要： An orbicular valvular conduit which has no moving parts and is configured to facilitate unidirectional flow of a primary fluid stream by utilizing a counterflowing diverted fluid stream to counteract any opposing fluid stream which flows in the direction opposite the primary fluid stream may include at least one conduit subunit. Each conduit subunit may include a fluid diverging section. A fluid converging section may extend from the fluid diverging section. A valve core may be disposed in the fluid diverging section and the fluid converging section. A primary flow passage may extend through the valve core to accommodate a primary fluid stream. A secondary core passage may be formed by and between the valve core and the fluid diverging section and the fluid converging section. In the event that an opposing fluid stream develops in the primary flow passage in the direction opposite the primary fluid stream, the secondary core passage may accommodate a diverted fluid stream which reenters the primary fluid stream to oppose or impede the opposing fluid stream. The fluid converging section of each conduit subunit may be joined to the fluid diverging section of an adjacent conduit subunit along a section interface. The orbicular valvular conduit may be fabricated using machining, stamping or 3D printing techniques.

摘要： A throttling component and a conditioning and flowrate measurement device including a throttling component. The throttling component comprises a central throttling element and multiple peripheral throttling elements. The multiple peripheral throttling elements are sequentially sleeved on the exterior of the central throttling element, and are coaxial to the central throttling element; annular fluid channels are respectively formed between the central throttling element and its adjacent peripheral throttling element, and between adjacent peripheral throttling elements. A sensitive and clear differential pressure signal is generated while the throttling component stabilizes the flow, so that the accuracy and reliability of flowrate measurement can be improved.

摘要： The invention relates to distributing reactants more evenly across the interior space of a reactor vessel utilizing a distributor at the inlet end that initially directs the flow of reactants through a flange plate and a series of ring plates. The ring plates are physical spaced such that vapor along the wall of the inlet is mildly obstructed by the flange plate and the ring plates cause the vapor to alter course temper down any diverse velocities that may create hot spots within the catalyst bed.

摘要： A fluid pressure reduction device is provided. The fluid pressure reduction device includes a body and a diffuser. The body defines an inlet, an outlet, and a fluid passageway extending between the inlet and the outlet. The body is made of a first material having a first hardness. A seating area is defined within the body. The diffuser is removably coupled to the seating area and disposed within the fluid passageway of the body. The diffuser defines at least one flowpath for reducing a pressure of a fluid flowing through the fluid passageway. The diffuser includes a second material having a second hardness greater than the first hardness of the first material.

摘要： A fluid flow modifier device comprising: an inlet portion for receiving a flow of fluid; an outlet portion for outputting the flow of fluid; and a flow modifier portion disposed between the inlet portion and the outlet portion, the flow modifier portion comprising an outer portion comprising a closed cross-section to the flow of fluid and an inner porous portion configured such that at least a portion of the flow received in the inlet portion must pass through the inner porous portion to reach the fluid outlet. The fluid flow modifier device is ideally used to transition fluid flow between an fluid supply line and a fluid treatment zone—for example, a pressure water supply line and an ultraviolet radiation treatment device (e.g., drinking water treatment device).
