Abstract

PURPOSE:To prevent an O-ring from being abnormally deformed by a pressure by providing a holding ring, which has a diameter larger than that of a flange part further slidable while a cut split, to be arranged between the O-ring and the flange part. CONSTITUTION:A valve rod 2, which integrally forms a pair of flange parts 3a, 3b while provides a thread 14, screwed to a valve main unit 1, to be arranged, moves vertically sliding by turning a handle 11. Holding rings 6a, 6b, consisting of tetrafluoroethylene, provide diagonal cut splits 7 being formed so as to be pressed spreading larger than the external shape of the flange parts 3a, 3b and fitted so as to hold an O-ring 5 to be put between the flange parts 3a, 3b.
