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： The present disclosure provides an exhaust assembly for an aerostat, including a valve base (2) provided with a valve port (1), and a valve cover (3) that selectively covers the valve port (1), and further including: a motor driving mechanism and a transmission mechanism that are arranged on the valve base (2). The motor driving mechanism propels the transmission mechanism to drive the valve cover (3) to selectively cover the valve port (1). When the valve cover (3) is in a position where the valve port (1) is open, the valve cover (3) is arranged at an angle with respect to a plane at which the valve port (1) is located. A purpose of the present disclosure is to provide the exhaust assembly that is for an aerostat and whose exhausting pressure can be flexibly adjusted, and an aerostat provided with the exhaust assembly.

摘要： A valve assembly includes a body having a fluid inlet disposed on a first end of the body and a fluid outlet disposed on a second end of the body in fluid connection with the fluid inlet. The valve assembly further includes a push-to-connect fitting which is integral to the body and configured to connect to an end of a pipe, a stem configured to seal the body in a first position and configured to allow fluid to flow from the fluid inlet of the body to the fluid outlet in a second position, and a connector surrounding at least part of the push-to-connect fitting. The body is configured to house a sealing ring. The push-to-connect fitting is configured to communicate the fluid inlet with the end of the pipe. The sealing ring secured by the push-to-connect fitting is configured to provide a seal between the fluid inlet and the end of the pipe.

摘要： A bypass system has a source of a fluid to be cooled and a heat exchanger for selectively cooling fluid. A piston is moveable along an axis allowing movement of a valve poppet toward and away from the valve seat. The piston moves with a rigid seal carrier. The rigid seal carrier and the piston move within a valve housing. A wax element is disposed on an opposed axial side of the rigid seal carrier relative to a chamber, such that the wax element expands as a temperature of the fluid to be cooled increases, and causes the valve poppet to move against the valve seat. A bypass valve is also disclosed.

摘要： A pressure regulator comprising a housing containing a channel arranged to communicate a fluid from a fluid inlet to a fluid outlet, said channel comprising a valve seat and closure member with said closure member operable with valve seat to control fluid flow through the channel and; wherein the housing comprises a resilient diaphragm in fluid communication with the fluid and in physical communication with the closure member such that the diaphragm is operable to deform in response to a change in pressure of the fluid and such that deformation of the diaphragm causes the closure member to change position and; wherein a hollow member is located in the channel and the stem of said hollow member defines a narrow path between the channel and outside of said stem in a region proximate to the fluid outlet such that fluid passing through the channel is communicated from the fluid inlet to the fluid outlet via said narrow path such that the pressure of the fluid emerging from said narrow path into the channel is communicated to the diaphragm via the inside of the hollow member.

摘要： A valve assembly includes a body, a fitting, and a stopper assembly. The body has a first end and a second end. The body includes a connector portion positioned at the first end, a nozzle portion positioned at the second end, and an intermediate portion connecting the connector portion to the nozzle portion. The connector portion includes a peripheral wall having a crimped end that defines a fluid inlet. The nozzle portion defines a fluid outlet. The connector portion, the intermediate portion, and the nozzle portion cooperatively define a fluid flow path extending from the fluid inlet to the fluid outlet. The fitting is disposed within the peripheral wall. The fitting is held within the peripheral wall by the crimped end. The stopper assembly is coupled to the body along the intermediate portion. The stopper assembly is configured to facilitate selectively restricting a flow along the fluid flow path.
