【摘要】：礦用液壓閥與立柱、千斤頂?shù)仍考夹枰M(jìn)行高壓與低壓密封性能試驗(yàn)。為了提高檢測(cè)過(guò)程自動(dòng)化水平,減少人為干預(yù)試驗(yàn)過(guò)程引起的操作失誤,設(shè)計(jì)出可以自動(dòng)切換低壓與高壓檢測(cè)回路的低壓儀表保護(hù)閥。該閥可以設(shè)定保護(hù)壓力,低壓與高壓情況下密封可靠,結(jié)構(gòu)緊湊。并對(duì)設(shè)計(jì)過(guò)程的分析計(jì)算作了解釋和說(shuō)明。
[Abstract]:Hydraulic valves, columns, jacks and other components need to carry out high-pressure and low-pressure sealing performance tests. In order to improve the automation level of the test process and reduce the operation errors caused by human intervention, a low-pressure instrument protection valve which can automatically switch the low-voltage and high-pressure detection circuits was designed. The valve can set protection pressure, low pressure and high pressure sealing reliable, compact structure. The analysis and calculation of the design process are explained and explained.
