技术性能与特点：
1. 沉水式液压阀门试验台由操作控制台和夹紧装置两部分组成，夹紧装置可整体潜入水中，由液压系统控制其升降。
2. 适用于对法兰连接形式阀门进行强度、密封和上密封性能的试验。
3. 采用夹紧爪抱压法兰方式压紧，对被试验阀门无外力影响，因此符合GB/T13927-92,JB/T9092-99及API598所规定的要求。
4. 左、右夹紧盘都可进行90度翻转，便于对阀门进行性能试验。
5. 试验介质可由水，气或者煤油，由客户自选。
6. 已配置高、低压水泵及增压系统，可直接进行水压试验。预留一个气泵接口，如采用气为介质则气泵需用户自配。
7. 试验台用水及油等试验介质可循环使用。
8. 设有液压自动卸荷系统，使用时，高压状态与卸荷状态自动切换，有效降低了油温，延长设备使用寿命。
9. 另有触摸屏控制、显示和打印测试压力系统可选配。
Technical performance and feature:
1. YFT-Z serie has two parts: control part and clamp part（water tank）. The whole claws clamp part can be submerged under water, it is controlled by hydraulic system.
2. YFT-Z serie hydraulic valve test bench suitable for flange valve’s shell test, seal test and back seal test.
3. Using clamp to hold the flange, so there’s no external force effects on the test valve. It’s accord with the equirements of GB/T13927-92,JB/T9092-99 and API598.
4. Left and right workbench both can turn over 90 degrees, for the convenience of carrying valve and seal test.
5. Test medium can be choosing by user, water, air or kerosene.
6. Test bench has low pressure water pump and water booster. There is an air connection reserved for air pump.
7. Water and hydraulic oil cycle use.
8. The test bench has an automatic oil pressure discharge system. When using it, the high pressure condition and the relief pressure condition can be changed by itself. So it can reduce oil temperature, elongate life of test bench.
9. PLC control, touch screen display pressure diagram and printer system is optional.
