JLD butterfly valve test bed is a special type used for butterfly valve performance tests. The machine set of mechanical, electrical, fluid and hydraulic pressure device for circulating water system in one, table with clamping claws clamping cylinder direct-drive valve to achieve the test, so that the claw force uniform, clamping reliable, clip bear claw radial mobility features with cylinders, connecting rod, achieving simultaneous radial movement of claws to ensure the size of the diameter of the butterfly valves of different tests, when sealed, if the butterfly valve with a clamping flange, not the butterfly orchid from a direct extension of hydraulic clamps are clamped butterfly valve plane can be tested. The aircraft can be directly whether the leaking valve cavity bubbles or risk, such as the test intensity blind stamped on the plate can be sealed in the machine can do the valve electric device on the torque and 90-degree opening and closing test. The machine comes with hydraulic pressure for the pumps, storage media can be recycled to use. The use of clean water must be added anti-rust agent, so as not to rust and impact of post-test valve hydraulic pressure device for the use of normal function.
