A valve apparatus for a gate pump is provided to prevent power efficiency degradation of a gate pump due to the self-load of a gate valve and outer water pressure and prevent unnecessary leakage by improving the air-tightness of a valve opening and closing part. An auxiliary pipeline(2), a gate pump, a gate valve(4), and a deceleration device(5) are coupled to a floodgate body. The gate valve comprises a valve disc(41) having a disc shape and a rotation guide flange formed on the upper center of the valve disc. A hinge shaft(43) having a driven clutch plate(431) is mounted on the rotation guide flange. A buffer sheet ring has an elastic hollow to have elastic air-tightness on the inner circumference of the valve disc. The deceleration device transfers the rotation power to the gate valve due to circuit control according to selection and automatically controls the opening and closing operation of the gate valve. |
