Claims

[Scope of utility model registration request]

It is equipped with an inflow side flange connected to a branch pipe provided by branching to the purified liquid supply pipe, a discharge side flange connecting the discharge pipe, and an elastic valve plate inserted between both flanges, where the inflow side flange is connected to the valve plate. The valve plate has a peripheral edge that fits into the inner hole of the outflow side flange, and a mounting portion protrudes from a part of the free end, and the valve plate mounting portion is formed by both the inflow and outflow flanges. A relief valve for a grinding fluid purifying device, characterized in that the valve plate is clamped and tightly pressed against the contact surface, and the free end of the valve plate is allowed to bend into the inner hole of the outflow side flange by a set hydraulic pressure in the branch pipe. .
