Zhejiang YOUJI Machinery Technology Co.,Ltd. valve test bench 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 Equipment Valve test equipment can be used for a variety of applications, such as intermediate and final inspections by valve manufacturers, testing of new valves on delivery, and routine or post-maintenance testing of valves in service. These include, for example, pressure testing of valve housings, leakage testing of valve seats, and set pressure testing of safety valves. Other components can also be pressure tested, such as tanks, motor housings, pump housings, pipe fittings, insulators etc. Special clamping devices may be required to clamp these test pieces. Structure and working principle Valve test equipment is composed of hydraulic system, electrical control system, high and low pressure water pump pressure supply device system, oil pressure, water pressure instrument system, control valve system, clamping workbench system and hydraulic medium storage circulating water tank. The test process and results meet relevant regulations and requirements. The valve test equipment adopts flange end face sealing, holding pressure claw to directly clamp the valve, and the back of the flange is compressed. The clamping mechanism is directly driven by the clamping oil cylinder of the clamping claw. The axial direction of the clamping claw can move forward and backward, which is not limited by the thickness of the flange. The radial movement is composed of oil cylinder and lever to realize the radial synchronous movement of each clamping jaw. The radial clamping jaw can move forward and backward. It is not limited by the diameter of valve flange. There is no external force on the test valve. The left end of the test bench can move horizontally left and right, and the pressure test is not limited by the structural length of the test valve; The right end can be turned over 90 degrees to facilitate the sealing and air tightness test of the valve. The high-pressure water pump is powered by the 4-7 bar air pressure system and automatically reverses through the electrical control reversing valve to make the high-pressure water pump work automatically and reciprocally. The water suction check valve and water outlet check valve are interchanged to continuously supply pressure to the tested valve to meet the pressure requirements of the tested valve. It is applicable to the high-pressure water seal test of 1.1 times the nominal pressure, the high-pressure water shell test of 1.5 times the nominal pressure and the low-pressure air tightness test of 4-7bar for flange valves.
Zhejiang youji machinery technology co., ltd. 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.
