Abstract

The gate (26) of the valve has a pair of identically shaped closing discs (100, 102), the annular hardened seating surfaces (104) of which come into closing contact with a valve seat (56). During the opening and closing of the valve, tongues on the sides of the closing discs slide in vertical grooves. The closing discs (100, 102) are separated from one another by an annular spacer (120), the diameter of which is less than the diameter of the seating surfaces. The spacing ring is secured in position by raised portions on the inner side of the closing discs (100, 102) which engage from the inside in the spacer ring (120). The spacer ring guarantees the correct width of the gate (26) in accordance with the amount of wear. The difference in diameter between the valve seating surfaces (104) and the spacer ring (120) provides the gate with increased flexibility. <IMAGE>
