使用操作方法 The operation method
一、被試閥門的裝夾
按該測試臺型號選擇通徑大不的被試閥門,調整測試臺的左向工作裝夾位置,將被試的閥門放在測試臺左向夾緊工作臺的密封盤中心,點動 <左徑向進>按鈕,將壓爪進到被試閥門的法蘭背後麵的正確位置,按<左軸向緊>按鈕<參照夾緊油缸所需壓力對照表 >中的液壓壓緊系統<增>PN值,按<左向增壓>按鈕,調節<增壓調節閥>,將<左增壓表>的壓力和夫緊油缸所需壓力對照表中的閥門通徑、壓力、 PN值相同,一切正確後,關閉<氣總開關、氣表開關泄壓開關>。開<水總開關、左向進水>既可作被試閥門密封測試。
二、水壓、水泵的使用方法
調整水源電接點壓力表,水泵開關<低壓水泵>開,先把被試閥門內部水註滿,低水壓力表為O 5MPa內水已滿,關掉水泵開關<低壓水泵>關。再按<高壓水泵開>調節供水泵壓力調節閥,<供水泵,液壓系統減壓閥J一25B>把液體試壓壓力達到和被試閥門密封壓力及電接點壓力表值相同時,高壓水泵就自動停機,關閉 <總水開關>。保壓數分鐘後,水壓表無下降,測試密封完畢,開<泄壓開關 >,將被試閥門內的壓力泄壓,<水壓表>為零,可以放松被試閥門或同時繼續進行強度測試。
三、被試閥門強度測試裝夾
閥門密封測試完畢後,繼續進行作強度測試,左向夾緊不變,調整右向測試臺裝夾裝置,按<移動架進>按鈕,將移動架一端主盤密封盤,進到被試閥門法蘭的另一端相碰,參照左向程序,把右端壓緊,並對照 <夾緊油缸所需壓力對照表>中的液壓夾緊系統壓力 <增壓>PS值相同,開<右向進水>打開被試閥門密封後,參照<=,水壓、水泵使用方法,進行閥門強度測試。
四、被試閥門氣密封測試方法,<氣源用戶自備連接> 作氣密封測試時,隻能在左端進行密封測試將左邊工作主盤向上旋轉90度平麵,接<向上旋轉>按鈕,接<1>步驟程度,將被式閥門裝夾完畢,關閉 c水總開關、泄壓開關、右向進水,。開c氣總開關、氣表開關,,向被試閥立刻另一端內,註入清水,觀察被試閥門內的密封性能及氣泡。測試完畢關閉 <氣總開關>開<泄壓開關>,氣壓表壓力為零後,再將被試閥門卸下。
One, the clamping valve test was
According to the test model selection path not tested valve, adjusting test bench left to work clamping position, the subject s valve on the test bench to the left clamping table sealing disc center, move the left radial inlet < > button, pressing claw into the tested valve flange behind the correct position, press < left axial locking button < > reference clamping cylinder pressure required to control table > hydraulic pressing system < >PN value, press < left to boost button, adjust the pressure regulating valve >, < Table > will be left plenum pressure and husband tension cylinder pressure required control table the valve size, pressure, PN value is same, all right, off < gas switch, the gas meter switch pressure switch >. Open < water switch, left water inlet > can be tested valve sealing test.
Two, water pressure, water pump using the method of adjustment of water electric contact pressure gauge, water pump low pressure pump switch < > open, the valve test was full of internal water, low water pressure gauge of O 5MPa is already full, turn off the water pump low pressure pump switch < >. According to the high pressure water pump open > regulating water supply pump pressure regulating valve, a water pump, the hydraulic system pressure relief valve J 25B> liquid pressure test pressure is reached and the tested valve sealing pressure and electric contact pressure gauge value is same, the high-pressure water pump will automatically shut down, closed < > the total water switch. Holding pressure after a few minutes, hydraulic table without falling, the sealed test finished, opened pressure relief switch >, will be tried in the pressure relief valve, hydraulic table <> nil, can relax the tested valve or while continuing strength test.
Three, subjects valve strength test clamping valve sealing test is finished, continued strength test, left to the clamping unchanged, adjust right to test clamping device, press < frame > button to mobile, the mobile rack end main plate sealing disc, into the tested valve flange at the other end is touched, with reference to the right end of the left program, pressing, and control the clamping cylinder pressure required to control table > in < boost pressure hydraulic clamping system have the same >PS value, opened right water inlet > open valve test was sealed, with reference to them, water pressure, water pump using method, carries on the valve strength test.
Four, subjects valve air tightness testing method, the source user owned connection > gas seal test, only in the left sealing test will be left to work the master disc is rotated 90 degrees upward rotation plane, then < > button, then <1> steps degree, will be type valve is setup, close C the total water switch, pressure switch, right water inlet,. Open C gas switch, the gas meter switch,, to the tested valve immediately in the other end, into the water, to observe the subjects within the valve sealing performance and air bubbles. The test finished off the gas main switch > Open < > pressure switch, pressure gauge pressure is zero, then the valve test was unloaded.
