技术性能与特点：

1. 适用于DN50mm以下规格法兰连接、焊接和螺纹连接阀门的性能试验。

2. 兼备夹爪抱压式与顶压压紧两部分，将试验工件沉入水箱中，可上下升降及夹爪抱压部分具有90度翻转功能，特别适用于气体压力试验，操作使用方便。

3. 试验介质可由水，气或者煤油，由客户自选。

4. 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。

5. 试验台用水及油等试验介质可循环使用。

6. 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。

Technical performance and feature:

1. YFT-C type hydraulic valve test bench suitable for DN15-50mm flange, welding and threaded valve test.

2. Claws clamp part and impaciton cylinder parts are separated.

3. Test medium can be choosing by user, water, air or kerosene.

4. Test bench has low pressure water pump and water booster. There is an air connection reserved for air pump.

5. Water and hydraulic oil cycle use.

6. 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.
