摘要： Valve positioning systems may include one or more components and a controller. Components may include one or more electric-to-pressure output converters, relays, gas supplies, and/or actuators. A controller may adjust a position of a valve by sending a signal. The valve positioning system may individually monitor components and determine the condition of each component being individually monitored. The valve positioning system may determine if a component will fail prior to failure and/or determine if a problem will occur in a component prior to the problem occurring.

摘要： Systems that utilize a power grid to monitor and control fluid flow within a water system are presented. The system can have first and second docking stations configured to process signals produced by respective first and second sensors. The docking stations are preferably user-pluggable into a power grid such that the docking stations can communicate with other docking stations, sensors, or a remote monitor. Methods of refitting an existing water system to monitor and control water consumption are also presented. Sections of the existing system can be replaced with new sections that include at least one valve and sensor to monitor and control fluid flow through that section.

摘要： A valve apparatus has a valve (1), an actuator (2) and a leakage sensor (3). A body (4) of the valve has first and second valve chambers (6, 8) connected to respective valve ports (10 & 12, 14 & 16) and joined by an intermediate passage (18). The valve can be set by the actuator to any one of three valve configurations. In an ‘open’ configuration the intermediate passage is open to interconnect the first and second chambers. In a ‘closed’ configuration, the intermediate passage is closed by first and second seals (24, 26) seated at respective locations in the passage to seal respectively between the first and second chambers and a leakage chamber (28) at the portion of the intermediate passage between the two seals. In a ‘cleaning’ configuration one of the seals is unseated to connect a respective one of the first and second chambers to the leakage chamber, while the other seal remains seated. The leakage sensor is connected to the leakage chamber to provide a signal indicative of a leakage flow from the leakage chamber.

摘要： A leak detection system is described for detecting a leak through a closed valve disposed between an upstream pipe and a downstream pipe of an industrial process. An insertable plate is coupled to the valve in the pipe in-line with the fluid flow. A sensor couples to the flow and provides a signature output. A leak detector is coupled to the sensor and adapted to detect a leak through the valve based upon the signature output.

摘要： Pipelines are controlled by specifying operations along them. Control specifies sequential control values defining operations at each station to control the pipeline state. The time-dependent state is determinable by software calculations using continuous measurements along the pipeline. Forecasted deliveries dictate that the current pipeline state must change by future time (T). Control sequences are determined at pipeline stations to exercise optimum pipeline control while achieving predetermined goals from the current state to a sustainable target state which supports future deliveries by simulating current pipeline states through time interval T, while satisfying time-dependent forecast deliveries. An initial computable control set is iteratively improved and evaluated by computing the gradient of pipeline operational cost, costs of missing target(s), and costs of violating constraints by solving an adjoint problem each time the simulation is made. The gradient information, using second-order approximations to the N-dimensional cost, rapidly produces optimizing solutions using an accelerated iteration.

摘要： A test assembly for water-flow alarms having a housing made up of two sections. One section includes a control valve, and the other section a viewing chamber. The control valve is capable of a passing water therethrough at two distinct flow rates, one of which being equivalent to the flow rate passing through the orifice of a sprinkler. The viewing chamber contains a uniquely designed sight module therein through which the flow of water can be viewed. By incorporating the test assembly within a sprinkler system it is possible to reliably test a water-flow alarm without activating the sprinkler within the system.

摘要： A high pressure in-line test valve (42) is positioned to block off a first fluid pressure source (10) acting on a control valve means (32 and 34) and to provide communication with an alternate test fluid pressure source (138) for testing the control valve means. The test valve (42) has a central bore (70) in which a depressible piston (78) is positioned for longitudinal movement between a seated extended position (FIG. 2) blocking the first fluid pressure source and simultaneously communicating test fluid to the control valve means, and an unseated retracted position (FIG. 3) re-establishing communication between the first fluid pressure source and the control valve means and simultaneously blocking the alternate fluid pressure source (138) with a dual sealing means. The dual sealing means includes a primary metal-to-metal sealing member (84 and 114) and a secondary annular sealing member (120) providing a test valve that is capable of withstanding high working pressures such as 20,000 pounds per square inch without leaking fluid from the first fluid pressure source ( 110) to the alternate fluid passage (104) or externally of the test valve. The dual sealing means are releasable upon engagement of a hollow stinger (124) which actuates the piston (78) into its seated position and provides a connection means (134) to supply a test fluid from an alternate fluid pressure source (138) for testing of the control valve means (32 and 34).

摘要： A valve positioner that is configured to detect fugitive emissions on a valve. The configuration may include a sensor that resides in proximity to the device. The sensor may connect to a control unit, preferably with operating hardware that can process signals. This arrangement may secure to structure of the valve. In one implementation, the sensor can connect to connections that exist on a circuit board. This feature permits upgrades to devices, including those in assembly or those in the field, with minimal impact to design or performance.
