技術(shù)性能與特點(diǎn)：

1. 沉水式液壓閥門(mén)試驗臺由操作控制臺和夾緊裝置兩部分組成，夾緊裝置可整體潛入水中，由液壓系統控制其升降。

2. 適用于對法蘭連接形式閥門(mén)進(jìn)行強度、密封和上密封性能的試驗。

3. 采用夾緊爪抱壓法蘭方式壓緊，對被試驗閥門(mén)無(wú)外力影響，因此符合GB/T13927-92,JB/T9092-99及API598所規定的要求。

4. 左、右?jiàn)A緊盤(pán)都可進(jìn)行90度翻轉，便于對閥門(mén)進(jìn)行性能試驗。

5. 試驗介質(zhì)可由水，氣或者煤油，由客戶(hù)自選。

6. 已配置高、低壓水泵及增壓系統，可直接進(jìn)行水壓試驗。預留一個(gè)氣泵接口，如采用氣為介質(zhì)則氣泵需用戶(hù)自配。

7. 試驗臺用水及油等試驗介質(zhì)可循環(huán)使用。

8. 設有液壓自動(dòng)卸荷系統，使用時(shí)，高壓狀態(tài)與卸荷狀態(tài)自動(dòng)切換，有效降低了油溫，延長(cháng)設備使用壽命。

9. 另有觸摸屏控制、顯示和打印測試壓力系統可選配。

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.
