摘要： A sampling and rejection device for a boiler or steam generating system is described. The sampling and rejection device receives the condensate or fluid and allows a volume of the condensate to liquefy or the fluid to build up in the interior of the sampling and rejection device. One or more conductivity, pH, and temperature sensors or probes are positioned in the sampling and rejection device to measure the condensate. The sampling and rejection device includes a collection vessel to hold and temporarily store the condensate. The sampling and rejection device includes an outlet or a return line (to a central boiler) and a drain line. If the sensor measures undesirable conductivity, pH, or temperature in the condensate in the collection vessel, then a valve to the drain line is opened and the condensate is rejected.

摘要： A downhole valve for insertion in a production tubing string permits recirculation of fluid pumped into the casing annulus. The valve includes a cylindrical housing defining an opening, an internal mandrel disposed within the housing, defining a central bore and defining an opening, a valve between the housing and the mandrel, wherein said valve opens to allow fluid communication from the mandrel central bore to the annulus space in response to a pressure differential between the mandrel central bore and the annular space, and biasing means for biasing the valve in a closed position. The valve may be set within a completion string by wireline techniques

摘要： The invention relates to a method and apparatus for determining the switching pressure of a safety appliance, which is adapted to safeguard an installation against exceeding, or falling below, a gas pressure. An increasing pressure is applied to the safety appliance such that the applied increasing pressure rises in accordance with an exponential function. Due to the constant relative increase in the pressure supplied to the safety appliance, it is not necessary to take into account settings of the safety appliance. Errors resulting from incorrect settings by the user are thus prevented.
摘要翻译：本发明涉及一种用于确定安全装置的开关压力的方法和装置，其适于防止超过或低于气压的装置。对安全装置施加增加的压力，使得所施加的增加的压力根据指数函数而升高。由于供应给安全设备的压力恒定相对增加，所以不必考虑安全设备的设置。因此防止了由用户的不正确设置导致的错误。

摘要： The pressure valve is actuated by pressurized fluid and has a housing with a high-pressure space and a low-pressure space separated from each other by a partition. The partition has a bore accommodating a valve member. Axial passages are made in the body of the valve member for establishing alternating communication between the spaces upon the displacement of the valve member. The low-pressure space receives a pressure-relief valve spring-urged away from the partition and movable by the action of pressure selectively supplied to initiate relieving of the high-pressure space. The pressure-relief piston has an axial bore. The pressure valve incorporates an auxiliary piston in the axial bore of the pressure-relief piston and it cooperates with the valve member to displace the latter. The body of the valve member is provided with throttling passages communicating with the axial passages. The flow passage area of the throttling passages is substantially smaller than that of the axial passages, and the throttling passages are arranged so that during the high-pressure space pressure-relieving operation, the two spaces communicate via the throttling passages until the effort applied to the valve member by the auxiliary piston overcomes the effort applied to this valve member from the high-pressure chamber.

摘要： A pressure balancing valve has a pair of fluid ducts for hot and cold water, a butterfly type valve is located in each duct, a pressure cavity is provided that is in communication with each duct, and a resilient diaphragm mounted in the cavity converts pressure differential between the ducts into positional displacement of a rod-like pressure plate linkage secured to the butterflies. The butterflies pivot to alter fluid flow in the ducts until substantially equal pressures appear at the outlets of the ducts.
