摘要： A safety structure for detecting fluid leakage from a valve having an exposed end of a rotatable valve stem connected to a valve element within the valve for rotating the valve element between an open and a closed position. The safety structure comprises a jacket, and an elongated handle extension disposed within the jacket for rotation about its axis. The handle extension includes an end which extends outward from the jacket for turning the handle extension. The jacket terminates in an annular flange which is attached to the valve in an isolating configuration having the exposed end of the valve stem covered, and the handle extension connected to valve stem via a slot on the lower end of the handle extension and a pair of opposed flats on the covered end of the rotatable valve stem over which the slot extends for transferring the rotation of the handle extension to the valve stem. A sealed chamber in the jacket surrounds the elongated handle and extends along the handle in the isolating configuration to communicate with the rotatable valve stem and isolate the covered end of the rotatable valve stem. A leakage detector is connected to a sniffer port in the jacket which communicates with the sealed chamber and detects leakage from the valve around the rotatable valve stem. A fluid reservoir is connected with a collection port in the jacket which communicates with the sealed chamber and collects fluid leakage from the valve around the rotatable valve stem.

摘要： A portable (handheld) volatile organic compound monitoring system for monitoring, for fugitive emissions, a device that includes a coded identification tag. The system includes a housing, a tag reader, analysis chamber structure, a sample probe coupled to the analysis chamber, and pump structure for drawing a gas sample to be analyzed through the sample probe into the analysis chamber. Ionization apparatus is coupled to the analysis chamber for ionizing a gas sample drawn into the analysis chamber from the device being monitored, and a sensor responsive to ionized gas in the chamber produces an output signal as a function of an ionization characteristic of the ionized gas. First storage stores a plurality of response factors as a function of various types of volatile organic compounds to be monitored, second storage stores tag information read by the tag reader, and circuitry responsive to tag information stored in the second storage selects a response factor from the first storage. Microprocessor apparatus responsive to tag information, selected response factor information, and the sensor output signal produces an output indicative of volatile organic compound (VOC) concentration at the monitored device.

摘要： A leak detector for a valve controlling flow of fuel to a combustion chamber employs a fuel concentration sensor in a sensing chamber placed downstream from the valve seat. The valve has a downstream chamber which is in communication by diffusion through an orifice, with a source of pressurized air. By injecting air into the downstream chamber through this orifice after the valve has closed and then measuring with the sensor the fuel concentration within the sensing chamber, excessive fuel leakage by the valve can be detected.

摘要： In accordance with the resent invention, there is provided a fugitive emission detection system for use in conjunction with a valve having a packing deign which includes a primary packing and a secondary packing. The valve further includes a leak port which is disposed within the valve bonnet between the primary and secondary packings. The detection system is operative to maintain the leak port in a normally open state. As a result, any fluid leakage past the primary packing is normally sent to the detection system, as opposed to being applied to and thus pressurizing the secondary packing. In the event of that a prescribed level of fluid leakage beyond the primary packing is detected, the leak port will be closed. The closure of the leak port facilitates the pressurization of the secondary packing.
摘要翻译： 根据本发明，提供了一种与具有包装主体的阀门结合使用的逃逸排放物检测系统，包括初级包装和二次包装。 该阀还包括泄放口，该泄漏口设置在第一和第二填料之间的阀帽内。 检测系统可操作以将泄漏口保持在常开状态。 因此，通常将通过主填料的任何流体泄漏送到检测系统，而不是施加到第二填料上并由此对第二填料加压。 如果检测到超过一次包装的规定水平的流体泄漏，泄漏口将被关闭。 泄漏口的关闭有助于二次包装的加压。

摘要： A process and apparatus for detecting small gas leaks in filled, pressurized containers. Each container to be tested, or that portion of each container to be tested, is enclosed and sealed in a test chamber. The space within the test chamber is evacuated to remove any residual gas or liquid within the chamber or on the surfaces of the container. Thereafter, the evacuated chamber is sealed and held for a predetermined period of time to permit any gas leaking from the container to accumulate and diffuse throughout the chamber. A quantity of carrier gas is then introduced into the test chamber and held therein for a predetermined period of time so that the carrier gas and leakage gas may co-mingle and equilibrate. This provides an equilibrated, fixed volume of carrier gas-leakage gas mixture, the leakage gas content of which is dependent only upon the leak rate of the container. The equilibrated mixture is then transferred to a sensor. The signal produced by the sensor for each container tested is compared to the sensor's response to a predetermined leak standard of acceptable value. A method is also provided to compensate for contamination of the carrier gas and for drift of the sensor.
