中文拼音 [bìsèxiànlù]
閉塞線路
英文
blocked track-
The assembly shall consist of two positive seating check valves located between two resilient seated shutoffs with a hydraulically balanced bypass line and four test cocks
這種總成應該由兩個正向密封止回閥，兩邊夾著兩個彈性閥座關閉閥，並配置一個液壓平衡旁路管線和四個測試旋塞構成。Series 774xdcda contains two independently operating check valves located between two resilient seated shutoffs with four ball valve type test cocks and a hydraulically balanced metered bypass line to detect low flows
系列774xdcda包含兩個獨立運行的止回閥，位於兩個彈性閥座關閉閥之間，並配置四個球閥型測試旋塞，以及一個液壓平衡儀表旁路管線用於檢測低流量。This model of valve overcomes such defects with the motor valve, piston - type electromagnetic valve as the post - wear defective closure due to the mechanical movement, the soft membrane full of elasticity, the balance hole can not close water because the foreign matters and mud sand accumulate and block it up etc., the highly effective use of the unique circuit greatly raises the reliability of the switch, extensively used for ic card watermeter, infrared induced sanitary utensils, etc
Fck - 118 ：進水口出水口為1寸25內螺紋該型閥克服了如電機閥活塞式電磁閥機械運動磨損后的關閉不良。軟性膜片富有彈性，平衡小孔不會因雜質與泥沙的淤積堵塞使其關不住水，獨特線圈磁路的高效利用大大提高了閥開關可靠性，廣泛用於ic卡水表紅外線感應潔具等自動控水系統。Based on an analysis on the present situation and development of three kinds of signal systems ( the point system based on interrogator responsor, the quasi - moving block system based on digital track circuit and the moving block system based on wireless data transmission ) in urban rail transit, some suggestions on the localization of signal system of urban rail transit are put forward
