valve test bench
valve testing
It's mostly suitable for the seal pressure of the flange straight connection valve and performance test of the valve body strength pressure; The packing method adopts the flange terminal seal, holds the press claw clamp and carries out the working test to the valve flange reverse side.The test result has no the influence of outside force, fully meet the GB/T 13927-2008, JB/T 9092-99, the API 598 requirements.
During the course of presseure protection of water or air test, any button can not work under the
condition of which the tested valve cavity has high pressure, it can work nornmally until leaking the
pressure to no pressure (make sure safety while working).
The test bench is equipped with an automatic oil pressure discharge system. As it is u of tsed,
a high pressure condition and pressure discharge condition can be changed over to effectively reduce the oil temperature, elongate life of the test bench and save energy.
5. 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.
