使用方法及操作程序Methods of using and operating procedures
    一、壓緊：點動按鈕(徑向外退)，選擇和閥門適應的密封盤，放置在工作臺中心位置，將被試閥門放置在密封盤上。按點動按鈕(徑向內進)將壓爪移動在閥門法蘭所需位置，再按按鈕(軸向壓緊)。
    二、增壓：按照《夾緊油缸所需壓力對照表》中公稱通徑(DN)，公稱壓力PN增壓。按動按鈕(軸向增壓)同時調節軸向增壓調節閥將增壓壓力升到表中所需壓力既可，(註：增壓按鈕可以多次點動，每次間隔時間若5—10秒鐘左右)。
    三、氣源升壓：液壓夾緊，增壓一切完畢後。打開針形閥門氣源總開關(工作進氣)再開鈕子開關(自動、手控)在自動進行氣源升壓狀態時選定壓力表，高壓和低壓，如果是高壓、關閉低壓壓力表開關，調節好電接點壓力表的適應壓力，和f氣源增壓調節閥)。
    四、被試閥門進口壓力升高時，當壓力達到整定壓力的90％以後，升壓速度應不超過O．01MPa，觀察並記錄被試閥門的整定壓力。然後降低閥門進口壓力，使被試閥門重新回到密閉狀態。調節閥門進口壓力並使之保持在密封試驗壓力。檢查閥門的密封性能。
    五、氣源的泄壓：當測試閥門試驗完畢時，並掉(自動、手控)開關、關閉(氣源總開關)，打開泄壓針形閥工作泄壓、到沒有壓力時可將工件放松。
A:, press button ( move radially outer back), and a valve adapted to seal plate, placed in the center of table position, will be placed in the sealing disc valve test. According to move the button ( radial inlet within the pressing claw ) will move in the valve flange in the desired position, then press the button ( axial pressing ).
In two, booster: according to clamping cylinder pressure required to control table of the nominal diameter ( DN ), nominal pressure PN booster. Press the button ( axial pressure ) at the same time adjustment of axial pressure regulating valve will boost pressure rise to the table in the desired pressure can, ( Note: Booster button can repeatedly move, each interval if 5 - 10 seconds ).
Three, boost: source of hydraulic clamping, boost after every. Open the needle valve gas source switch ( work intake ) open toggle switch ( automatic, manual control ) in automatic air boost state when the selected pressure gauge, pressure and low pressure, if high pressure, low pressure gauge switch off, adjust good electric contact pressure gauge to pressure, and f gas pressure regulating valve ).
Four, subjects valve inlet pressure increases, when the pressure reaches the set pressure of 90% later, boost speed should not exceed O.01MPa, observe and record the test valve set pressure. Then lower the valve inlet pressure, the valve test was returned to the closed state. Regulating valve inlet pressure and to maintain the seal test pressure. Check the sealing performance of the valve.
Five, air pressure relief valve test: when the test is finished, and fall ( automatic, manual control switch off ( ), gas source switch ), the needle valve open pressure relief work relief, to no pressure when the workpiece may be relaxed.
