    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.
