A system for automatically evacuating liquids from natural gas pipelines. An embodiment may be used for associated drip vessels and other containers and gas wells. The system includes a tank, a compressor, and an electric generator system. The system evacuates liquid from a pipeline by creating a pressure differential between the pipeline and the tank. When adequate pressure differential is achieved, liquids flow into the tank from the pipeline. When liquids are removed, the system shuts down and awaits a run signal. The system is suited for remote locations, due, in part, to the use of an automatic generator capable of providing power to the compressor and to the CPU as necessary. Liquid removal may be determined by measuring tank pressure at time intervals and determining a rate of change of tank pressure for indicating blow through. The system utilizes the same pipeline tap for liquid removal and gas injection.

In a steam trap comprising a seat valve that is adapted to be switched over between an open position for a first discharge state with large throughput and a closed position for a second discharge state with small throughput, the closure element and the seat of the seat valve define, at the closed position, a two-part passage, said passage having a jet cross-section, which first decreases in size in the discharge direction and, subsequently, re-increases in size, and being delimited by the seating area, the sealing face and at least one, only local control groove in the sealing face and/or the seating area. In the aseptic double seated valve the steam trap serves to carry out a flushing cycle as well as a sterilization cycle in a filling plant.

A steam trap is provided comprising a housing having formed therein a seat for a closure element between a steam and/or condensate inlet and an outlet, the closure element being adapted to be switched between a closed position in the seat and an open position raised from the seat, an annular gap is formed upstream of the seat in the final phase of the switching movement to the closed position and at the end position of the closed position, said annular gap being used for at least pre-filtering condensate and preventing particles from getting stuck in the seat as well as clogging of a nozzle.

An automatic drain discharge utilizing a vertically movable float to activate a diaphragm of a pilot valve to drive a drain plug. 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.

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 device for separating liquid from gas including: a fluid inlet configured to receive a fluid that includes a liquid and a gas; a gas outlet; a deflector positioned between the fluid inlet and the gas outlet, the deflector obstructing a path from the fluid inlet to the gas outlet; and a liquid channel adjacent to a liquid outlet; wherein the deflector is configured to deflect the liquid to the liquid channel; wherein the liquid deflected to the liquid channel exits the device through the liquid outlet; and wherein the gas flows around the deflector and exits the device through the gas outlet.

A drain valve including a housing having a float chamber, a piston chamber, and a plenum communicating with the piston chamber through a seat. The housing has a liquid inlet passage, and an outlet port. The drain valve has a tube passage communicating with the piston chamber. The drain valve includes an annular float. The drain valve includes a seal body connected to the float and rising away from the tube passage when liquid is in the float chamber. The drain valve includes a piston slidably mounted in the piston chamber having a head that moves away from the seat when gas enters the piston chamber. The piston includes a valve element that moves as the piston head moves to expose the liquid inlet port and allow liquid to flow from the liquid inlet passage through the plenum and into the liquid outlet passage.

An assembly for a condensate draining device for draining off a compressed-gas condensate includes a collecting chamber for receiving the compressed-gas condensate formed in a compressed-gas system, an electrically operated outlet valve for discharging the compressed-gas condensate from the collecting chamber, and an interface for attaching the assembly to an electronic module. The interface has a contact assembly for supplying the outlet valve with electricity from the electronic module. The interface is brought into one of several possible and different configuration states.
