CA 2404065
A visual signal of pressure between valve stem seals is given by a rising (26) ring, which moves upwardly with the upper stem (18) seal when there is pressure between the stem seals. The rising ring is held to the stem or valve body around the stem by a retaining (32) ring. The rising ring, in its up position, precludes removal of the retaining ring.
La présente invention concerne un signal de pression visuel entre des joints de queue de soupape donné par l'élévation d'une bague (26), qui se déplace vers le haut avec le joint de queue (18) supérieur lorsqu'il existe une pression entre les joints de queue. Cette bague qui s'élève est portée sur la queue ou le corps de soupape autour de cette queue par une bague de retenue (32). Dans sa position haute, cette bague qui s'élève empêche la bague de retenue de sortir.
