Claims

[Claims for Utility Model Registration] (1) In a valve device in which a scraper that comes into contact with the outer periphery of the valve body is interposed between the valve device main body and the gland box, the scraper is moved in the axial direction of the valve body. a plurality of outer peripheral side retaining plates that are formed spaced apart from each other along the valve body and are clamped by the valve body and the gland box when fitted to the valve body; and an inner periphery of the retaining plates. The inner peripheral side sliding contact piece is integrally provided with the valve body, the tip of which contacts the outer peripheral part of the valve body over the entire circumference, and is biased toward the valve body when the retaining plate is pressed. Rollover Y
A valve device characterized in that it is formed in an annular shape exhibiting a character shape. (2) In a valve device in which a scraper that comes into contact with the outer periphery of a valve body is interposed between a valve device main body and a gland box, the scraper is connected to an annular fixing portion that is fitted into the valve device main body; This annular fixing part protrudes inward from the ground box side and is inclined toward the bottom of the valve device body as it approaches the valve body, with the tip extending around the entire circumference of the valve body. A valve device characterized in that it is formed by a sliding contact piece that is in contact over the entire length.
