Claims

[Scope of utility model registration request]

Sliding valve body 1 that opens and closes the flow path F with sliding operation
is divided into two in the direction along the flow path F, and a pair of annular valve seats 4 that separately contact and seal the seal surfaces A and B of both divided valve bodies 1A and 1B are attached to the valve box. 2, and both the divided valve bodies 1A,
1B is formed so as to be relatively displaceable in the sliding direction of the valve body in accordance with the opening/closing operation, and the both seal surfaces A
, B are pressed against the valve seat 4 separately, and both the seal surfaces A and B are separated from the valve seat 4 as a result of the relative displacement of the two divided valve bodies 1A and 1B due to the valve opening operation. In a sliding valve in which cam surfaces a and b are formed on both the divided valve bodies 1A and 1B, respectively,
Both split valve bodies 1 in a direction along the cam surfaces a and b and perpendicular to the opening/closing direction of the sliding valve body 1
A valve body structure of a sliding valve in which an engaging portion 8 for preventing relative displacement between the valve bodies 1A and 1B is provided between the two divided valve bodies 1A and 1B.
