摘要： Devices, systems, and techniques relating to steam trap monitoring are described. These include battery-less steam trap monitors that run on power harvested from their environments, systems for acquiring steam trap monitor data for the traps in a facility or across multiple facilities, and techniques for processing steam trap monitor data to reliably determine the status of individual steam traps and potentially other system parameters.

摘要： An internal combustion engine cooling device includes a piston fixedly mounted within a device housing coupled to a plurality of flow paths through which cooling water flows, the piston disposed facing the interior of the device housing; a cylinder container that advances and retreats relative to the piston and has a flange valve that opens and closes a main flow path of the cooling water; a thermal expansion unit provided within the cylinder container that causes the cylinder container to advance and retreat due to volumetric changes attendant upon temperature changes; and a heat-emitting element provided within a piston casing that heats the thermal expansion unit when supplied with electricity. An insulating cover is provided to the exterior of the cylinder container at a portion of the cylinder container disposed facing the cooling water.

摘要： A valve for use with a showerhead assembly includes a housing having a threaded inlet for connecting to a water source and a distally located front face with nozzles. The nozzles are connected to the threaded inlet by a central conduit which is closeable by an electronically controlled valve. The valve is controlled by a processor which opens the valve based on temperature and audio signals above a predetermined decibel level.

摘要： Methods of operating a downhole tool comprise thermally-controlling the tool by sensing a temperature and controlling the tool in response to the sensed temperature. Thermally-controlled downhole tools comprise a control element responsive to a change in temperature that control flow into, out of, or through a wellbore. Methods and systems for servicing a wellbore comprise using a thermally-controlled tool comprising a thermally-controlled valve (TCV) in a wellbore. The TCV includes a valve body comprising an injection port for allowing material to flow into or out of the wellbore and an opening/closing mechanism for regulating flow of the material through the injection port in response to a change in temperature. The valve body may be coupled to a downhole conduit. A plurality of TCV's may be arranged in the wellbore to control the injection of steam into the wellbore or the recovery of oil from the wellbore.

摘要： An improved control device for a refrigeration circuit including a tubular casing having three spaced walls on its interior surface is disclosed. The first wall is a plurality of holes, the second wall has a longitudinal bore with a valve seat facing the first wall and the third wall includes at least one hole. A first bellows is attached to the inner surface of the first wall in the region between the first and second walls and has a valve element at its other end. The valve element includes a spherical sealing element which fits within the valve seat to control the flow of refrigerant through the longitudinal bore. A second bellows is attached to the interior surface of the third wall and has a valve control element extending from its other end into the longidudinal bore. When the level of refrigerant is below a predetermined level, the first bellows expands and the spherical sealing element contacts the valve seat preventing fluid flow through the longitudinal bore. This situation causes an abnormal reduction of pressure at the inlet side of the compressor, potentially causing the compressor to malfunction. A malfunction of the compressor is prevented by operation of the second bellows which expands due to the decreased pressure in the region between the second and third walls. Therefore, the valve control element is moved to the left, contacting the spherical sealing element and forcing it away from the valve seat to allow fluid to flow through the longitudinal bore.
