摘要： The inner diameter at the bottom of a case is gradually decreased from upper to lower positions. A bottom surface of a communication hole of a drain housing provided in an opening of the case has an inclined surface inclined toward a drain discharge hole. An outer marginal portion which is positioned at the uppermost position in the bottom surface of the communication hole is in the same plane as or lower than a marginal portion which is positioned at the lowermost position in an inner circumferential surface of the case and adjacent to the opening.

摘要： A float drain for an enclosure can include a basket to collect liquid from the enclosure, a sealing structure surrounding an outlet of the basket, and a float configured to seat against the sealing surface to prevent fluid flow out of the outlet and to rise off of the sealing surface due to buoyancy forces as the liquid collects in the basket. The float drain can include other features, including: ribs or other protrusions extending into an interior are of the basket to space the float apart from an inner wall of the basket; an angled orientation of the sealing surface; and a trough, at least partly defined by the sealing structure, to collect debris.

摘要： A device and method is provided for automatically removing water or accumulated moisture from a breathing circuit. The device includes a housing with breathing circuit flow entry and exit ports and a water drainage port. A buoyant body in the housing can mate with a float valve seat to seal the drainage port, and is moveable to open the drainage port when sufficient liquid accumulates in the interior space. The buoyant body displaces a substantial portion of the housing inner compressible volume. Water is automatically removed by a water vapor permeable container coupled to the housing receiving flow from the drainage port, or the device is coupled to a source of suction, further including at least one bleed port fluidly coupling the source of suction to the surroundings, acting with a valve element to equalize any pressure differential between the housing interior space and suction connection, when no water is accumulated in the device.

摘要： A float-based automatic drain valve automatically drains fluid from a compressed air cylinder; the cylinder includes a chamber with an inlet and an outlet. The inlet is formed at the top of the chamber and connects to a low point of the compressed air cylinder to receive fluid therefrom. The outlet is formed at the bottom of the chamber for discharging the fluid. A buoyant stopper disposed within, and not attached to, the chamber, seals the outlet when insufficient fluid is present within the chamber to float the buoyant stopper. Further, the buoyant stopper unseals the outlet and discharges the fluid when buoyancy of the stopper within the fluid overcomes forces seating the buoyant stopper at the outlet.

摘要： A condensate drain includes a body defining an interior space. An inlet opening is in fluid communication with the interior space of the body for allowing condensate to enter into the interior space, and an outlet opening is in fluid communication with the interior space of the body for allowing condensate to exit the interior space. A float is disposed in the interior space for movement within the interior space relative to the body generally along a float axis between a closed position in which the float blocks fluid communication from the inlet opening to the outlet opening and an open position in which the float permits fluid communication from the inlet opening to the outlet opening. The float is buoyant so that the float is moved to the open position by condensate as condensate fills the interior space of the body. The interior space and the float are sized and shaped so that the float is constrained to substantial alignment with the float axis.

摘要： An automatic drain valve for discharging accumulations of fluids and foreign materials from a fluid handling system. The drain valve (10) comprises a reservoir (14) defining a reservoir volume (15) and a thru-port (28), in fluid communication with the reservoir volume (15), that defines an inlet (30) and terminates in a drainage valve (82) for flowthrough communications with a fluid handling system. An actuating mechanism selectively actuates a valve operator. In the preferred embodiment, a pilot valve (41) is mounted in the reservoir (14) for selectively communicating pressurized air to a valve operator (57), such that the valve operator selectively opens and closes the drainage valve (82) communicating with the outlet (88) of the reservoir (14) for selectively draining the reservoir. The pilot valve (41) includes a sensor tube (42) which defines a valve seat (44) and includes a magnetized valve plug (46) for selectively engaging the valve seat (44), the valve plug (46) having a selected magnetic polarity. A level sensing float (52) disposed within the reservoir (15) carries an annular magnet (56) normally having a polarity opposing that of the valve plug (46) such that the annular magnet (56) acts upon the valve plug (46) selectively opening and closing the pilot valve (81) as the float (52) rises and falls from a raised position to a lower position with the level of liquid within the reservoir (14).

摘要： A valve for incorporation in a gas line through which liquid entrained gas passes, positions a valve seat across the line and arranges a sump adjacent to and upstream of the valve seat. A spherical valve element of a specific gravity less than the entrained liquid in the gas stream is positioned in the sump on a second valve seat therein communicating with a liquid outlet. Entrained liquid in the gas stream collects in the sump, floats the spherical valve element upwardly where the gas flow moves it horizontally into the valve seat in the gas line thus closing the gas line and opening the liquid drain.

摘要： The disclosure relates to an improved temperature responsive control arrangement. It includes a valve member, a chamber, and a bellows disposed in said chamber for controlling the position of the valve member in response to the temperature of fluid flowing through the chamber. The arrangement is particularly suited for use in steam traps. There are surfaces in the chamber for distributing fluid flowing through the chamber around the bellows to promote rapid expansion and contraction of said bellows with changes in temperature of the fluid flow through said chamber. The chamber has an outlet centrally located at one end thereof, and the distributing surfaces include a plurality of fluid inlets at the end of the chamber opposite from the outlet, the fluid inlets being distributed about the periphery of the chamber. Each of the fluid inlets conducts a flow of fluid into the chamber and each of the inlets is located so that a first portion of the fluid flowing through the inlet into said chamber is deflected by impact with the bellows across a lower end face of the bellows. The distributing surfaces further include a plurality of channels, each of the channels being associated with one of the inlets and forming a continuation thereof. Each of the channels at least partially defines a path along the edge of the bellows for a second portion of the fluid flowing through one of the inlets. Each of the channels has a deflector surface for deflecting the fluid flowing in the channel across an upper end face of the bellows. The deflector surfaces include bevelled end faces of each of the channels.
