Abstract
Una valvula con un medio integral para purgar la presion interna antes de que se separe un sombrerete para la valvula, de su acoplamiento con e l cuerpo de valvula; provisto de un agujero a traves del cuerpo de valvula. Esto permite que se iguale la presion interna de la valvula con la presion atmosferica, antes que se desmonte completamente el sombrerete del cuerpo de valvula. El agujero a traves del cuerpo de valvula tambien sirve como detector de fuga, al proveer una trayectoria para que los fluidos que pasan a traves de la valvula se fuguen al exterior del cuerpo de valvula, en caso de que falle el sello entre el sombrerete y el cuerpo de valvula, que puede ser detectada facilmente por quienes pasen, al inspeccionar el extremo expuesto del agujero, en el exterior del cuerpo de valvula.
