Valve test bench
Valve testing
Jlt-based test bed by the activities of the top clamps and hydraulic cylinder pressure method combining performance tests of various types of valves, the valves were tested without additional external forces affect the test results, in line with national standard valve testing requirements. The aircraft structure is divided into the hydraulic system, electrical control systems, working platforms and hydraulic clamping device for moving media storage devices and liquid recycling system, etc. Table clamping device consists of hydraulic cylinder direct-drive to achieve, so that the clip claw force uniform, clamping and reliable clamping device to the mobile capabilities through the traction rod formed by a hydraulic cylinder, the achievement of the clip claw radial synchronization mobile work. Table top clamping device set up the activities of beams, the main column. From the roof beams on the hydraulic cylinder pressure is not the achievement of the variety of different valves strength test. The machine has a water, gas, oil sealing performance and strength properties of the test. The machine used to seal the valve flange face to do positioning of the radial movement by the working table clamps to control the valve flange sizes were tested, and then clamps are pressed by the axial clamping method on the back of the valve flange to achieve test all kinds of different diameter size of the valve sealing test.

Jwt type welding type hydraulic valve testing bench, to both sides of the host frame seal disc and welding the inner hole of the valve for positioning and welding groove of the valve is sealed. By moving the machine frame to carry out experimental work of welding at both ends of the valve rupture plane clamping. Left to the frame and the sealing disc is fixed device, right to a moving frame to activities, were tested according to the distance of the valve is adjusted, valve to be tested without additional influence on the testing result of external force, and meets the requirements specified in the national standard of the valve is tested by.
The structure of the machine can be divided for hydraulic system, mechanical structure, electrical control system. About a frame, a moving frame, hydraulic pressure supply device and medium circulation water system components. The workpiece pressing using mobile rack cylinder direct drive to achieve the reliable compression. Right to the mobile frame can be adjusted according to the tested valve length distance, and has good performance, simple structure etc.. The machine is equipped with a low pressure pump and high pressure hydraulic pressure supply pump device.
Zhejiang YOUJI Machinery Technology Co.,Ltd.
Suitable for small diameter flange, welding type, internal and external thread forged steel valve pressure performance test, fully meet the requirements of gb/t13927-2008, jb/t9092-99, api598;
Both jaws clamp and pressure tight type and sinks the test pieces into the water tank, the lifting function, and is especially suitable for gas pressure test, operation and use are convenient,
The system is equipped with high and low pressure water pump pressure supply device;
Pressure test medium is water and gas, which is selected by users;
In the test of water or gas pressure in the process, the valve cavity has a higher pressure in the case of any one button does not work, has been pressure relief to the normal work;
The machine is provided with a hydraulic automatic unloading system, when in use, high pressure and discharge charge state automatic switching, effectively reduce the oil temperature, prolong the service life of the equipment, saving energy and reducing consumption.
Safety protection device with pressure test
Can be set with computer testing data management system.

Valve test bench valve testing
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.
