Proposed is a steam trap device strainer including: an intake pipe through which condensate water flows inside; a pressure gauge disposed at a side of the intake pipe; an intake chamber communicating with the intake pipe; a filter net disposed at a center in the intake chamber and configured to remove foreign substances; a foreign substance outlet formed at a lower portion of the intake chamber to discharge foreign substances; an intermediate channel formed over the filter net and laterally bending and extending; and a discharge pipe communicating with the intake chamber through the intermediate channel to discharge condensate water. The steam trap device further includes an intermediate chamber disposed at a bending of the intermediate channel, an adjuster assembly disposed in the intermediate chamber and having a plurality of perpendicular tunnels, and a temperature sensor disposed on a side of the discharge pipe in the strainer.

A manifold for a steam system is provided with a body forming a first chamber extending between an inlet and an outlet along a first axis and a second chamber extending from a face of the body along a second axis to intersect the first chamber. A first piston valve sub-assembly is disposed in the second chamber to enable and disable steam communication between the second chamber and a first port. A second piston valve sub-assembly is disposed in the second chamber to enable and disable steam communication between the second chamber and a second port. A handle is mounted for rotation relative to the face. A valve stem is connected to the handle and mounted for translation within the second chamber in response to rotation of the handle between four positions to individually activate and deactivate the first piston valve sub-assembly and the second piston valve sub-assembly.

A drain trap includes: a casing having a fluid channel; and a second valve mechanism including a second valve seat having a seat surface in a ring shape and a second valve body configured to be displaced to be separated from and seated on the seat surface of the second valve seat so that and the second valve mechanism opens and closes the channel. The second valve seat is held to be movable back and forth along a center axis of the ring shape such that the seat surface of the second valve seat and the seat surface of the second valve body are separated from each other and contact each other, and is held to be rotatable about the center axis of the ring shape.

The present invention relates to a bellows-type steam trap that comprises: a steam trap body having an inflow port formed at one side thereof, to which an inflow pipe is connected, and a discharge port formed at the other side thereof, to which a discharge pipe is connected, wherein a channel through which steam passes is formed between the inflow port and the discharge port; and a valve body which is installed in the steam trap body and can expand or contract to open or close the channel.

A multifunctional phase separation apparatus is provided herein. The multifunctional phase separation apparatus includes a porous tube, a phase separator, and liquid collecting modules. The porous tube includes a first entry port and an exit port. The phase separator includes a second entry port. The multifunctional phase separation apparatus also includes a reservoir. The reservoir is on a first end of the liquid collecting modules.

A method of maintaining a backpressure of a fluidic product is provided. The method includes pressurizing a first reservoir to a first predetermined pressure level using compressed air, delivering the fluidic product to the pressurized first reservoir until a current level of the fluidic product in the first reservoir reaches a first predetermined level, pressurizing a second reservoir to a second predetermined pressure level using the compressed air, delivering the fluidic product to the pressurized second reservoir until a current level of the fluidic product in the second reservoir reaches a second predetermined level, and controlling the backpressure of the fluidic product using the first reservoir and the second reservoir such that a discharge flow of the fluidic product is continuous.

A nozzle-type steam trap including a venturi nozzle, an orifice nozzle, or a tunnel structure resistance nozzle minimizes the outflow of steam even when a pressure difference between a drain-water inlet and a drain-water outlet of each nozzle fluctuates, the steam trap being compatible with any usage environments and enabling maintenance and inspection to be easily performed. The nozzle-type steam trap including the venturi nozzle, the orifice nozzle, or the tunnel structure resistance nozzle includes a means for sealing the nozzle by using a drain water. The nozzle-type steam trap further includes a plurality of steam inflow ports and drain-water outflow ports and includes a closure means for determining, for a selected one of the steam inflow ports and a selected one of the drain-water outflow ports, passages of steam and drain water. More preferably, the steam trap includes a swirl flow formation means in the vicinity of the nozzle.
