使用操作方法 The operation method
一、被试阀门的装夹按该测试台型号选择通径大不的被试阀门(阀门试压机)，调整测试台的左向工作装夹位置，将 被试的阀门放在测试台左向夹紧工作台的密封盘中心，点动 <左径向进>按钮，将压爪进到被试阀门的法兰背后面的正确位置，按<左轴向紧>按钮<参照夹紧油缸所需压力对照表 >中的液压压紧系统<增压>；PN值，按<左向增压>按钮，调节<增压调节阀>，将<左增压表>；的压力和夫紧油缸所需压力对照表中的阀门通径、压力、 PN值相同，一切正确后，关闭<；气总开关、气表开关泄压开关>。开<水总开关、左向进水>既可作被试阀门密封测试。
一、水压、水泵的使用方法
调整水源电接点压力表，水泵开关<低压水泵>开，先把被试阀门内部水注满，低水压力表为O 5MPa内水已满，关掉水泵开关<低压水泵>关。再按<高压水泵开>调节供水泵压力调节阀，<供水泵，液压系统减压阀J一25B>把液体试压压力达到和被试阀门密封压力及电接点压力表值相同时，高压水泵就自动停机，关闭 <；总水开关>。保压数分钟后，水压表无下降，测试密封完毕，开<泄压开关 >，将被试阀门内的压力泄压，<水压表>为零，可以放松被试阀门或同时继续进行强度测试。
二、被试阀门强度测试装夹
阀门密封测试完毕后，继续进行作强度测试，左向夹紧不变，调整右向测试台装夹装置，按<；移动架进>；按钮，将移动架一端主盘密封盘，进到被试阀门法兰的另一端相碰，参照左向程序，把右端压紧，并对照 <夹紧油缸所需压力对照表>；中的液压夹紧系统压力 <增压>；PS值相同，开<右向进水>打开被试阀门密封后，参照<=>水压、水泵使用方法，进行阀门强度测试。
四、被试阀门气密封测试方法，<气源用户自备连接>作气密封测试时，只能在左端进行密封测试将左边工作主盘向上旋转90度平面，接<；向上旋转>按钮，接<1>步骤程度，将被式阀门装夹完毕，关闭水总开关、泄压开关、右向进水。开c气总开关、气表开关，向被试阀立刻另一端内，注入清水，观察被试阀门内的密封性能及气泡。测试完毕关闭 <气总开关>开<泄压开关>，气压表压力为零后，再将被试阀门卸下。
One, the clamping valve test was in accordance with the test model selection path not tested valve ( valve test press ), adjust the test station 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 right place, press < left axial locking button < > reference clamping cylinder pressure required to control table > hydraulic pressing system < boost >; PN value, press < left to boost button, pressure regulating valve adjustment < >, the < left plenum Table >; pressure and husband tension cylinder pressure required in the comparison table 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.
Hydraulic, pump used 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 < >; 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.
Test valve strength test clamping valve sealing test is finished, continued strength test, left to the clamping unchanged, adjust right to test clamping device, press <; > mobile frame; button, 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 >; the hydraulic clamping system pressure < > PS booster; the same value, opened right water inlet > open valve test was sealed, with reference to <=> hydraulic, 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 plane, then <; > button to rotate, then <1> steps degree, will be type valve is setup, close 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 unl
OAded.
