Ivalve yokulawula ifilimu ye-pneumatic phantsi kweziphi iimeko ekufuneka isebenzise i-valve yokubeka i-valve indlela yokuhlola i-valve ye-pneumatic film elawula i-valve: Khangela ukuvuza kwebhokisi yokupakisha yokutywina kunye namanye amalunga Ubushushu bamanzi kwindawo yobushushu begumbi yi-1.1 amaxesha oxinzelelo lwe-valve yokulawula okanye amaxesha angama-1.5 ubuninzi boxinzelelo olusebenzayo, ngokwendlela yokuvula i-spool kwelinye icala le-valve elawulayo, enye isiphelo ivaliwe. Bamba uxinzelelo lwemizuzu eyi-10 ngelixa i-stem ihamba 1-3 amaxesha ngomzuzu. Akufanele kubekho ukuvuza ekudibaneni kwebhokisi yokupakisha yokutywina kunye namanye amacandelo. 2 Qwalasela ukuvuza ngexesha lokuvalwa ① Ukuhlolwa kokuvuza kwendlela yokutofa kwamanzi Izitulo ezibini ezilawula ivelufa zinokusetyenziswa ngendlela eqhelekileyo yokutofa kwamanzi ukujonga imeko yokuvuza. Uxinzelelo lwesignali yokungenisa kwigumbi legesi yefilimu ukuvala ivalve elawulayo (igalelo lophawu lwe-1.2kg/cm2 kwivalve yokuvala igesi, kunye noxinzelelo lophawu lwegesi evulekileyo nguziro). I-inlet yevalve yokulawula ifakwe kumanzi obushushu begumbi, kwimeko yokungabikho koxinzelelo kwelinye icala akufanele kube yinto ye-drip. ② Jonga ukuvuza koxinzelelo lwamanzi Le ndlela ingasetyenziselwa ukunqunyulwa kwengozi okanye ukuvala ivalve yokulawula isitulo esinye esiqinileyo, i-Angle elawula ivalve kunye nevalve ye-diaphragm. Uxinzelelo lwesignali yokufaka kwi-membrane yegumbi ukuvala umlawuli. Amanzi kwindawo yokushisa kwegumbi adluliselwa kwelinye icala le-valve elawulayo ngokunyanzeliswa rhoqo kwe-10kg / cm2 kwindlela yokuvula i-spool. Ubungakanani bokuvuza obulinganiswe kwelinye icala ngesitophuwotshi kunye nekomityi yokumeta akufunekanga ibe ngaphezu kwexabiso elivumelekileyo. Ivalve yokulawula ifilimu ye-pneumatic phantsi kweziphi iimeko ekufuneka isebenzise i-valve positioner 1. Xa isignali yokuphuma yomlawuli wombane isetyenziselwa ukusebenzisa i-actuator ye-pneumatic kwimeko yokulawula ikhompawundi, kufuneka ibe nomsebenzi wokumisa. Xa isignali yemveliso yomlawuli wombane isetyenziselwa ukusebenzisa i-actuator ye-pneumatic, kufuneka ibe nomsebenzi wokumisa ngaxeshanye, inokusebenzisa i-2 ye-electric-gas positioner 2, intshukumo yesikhundla ezibini kwizihlandlo zolungelelwaniso lwentshukumo akukho ntwasahlobo okanye ipiston. i actuator yintshukumo yeendawo ezimbini, xa ifuneka ukuba ibenolungelelaniso olulungelelanisiweyo, akukho mthombo okanye ipiston actuator enendawo ezibini, xa kufuneka ibenolungelelwaniso olulungelelanisiweyo, kufuneka isebenzise isihleli sevalvu. Kufuneka kusetyenziswe indawo yokubeka ivalve. I-3, ngexesha lokuhluka koxinzelelo oluphezulu phakathi kweziphelo ezimbini zevalve 10kgf/cm medium kwi-spool unbalance force inkulu, xa △P> 10kgf/cm2, i-medium kwi-spool force unbalance inkulu, ngokuphucula umoya. Umthombo woxinzelelo lwesimo ukufikelela kumandla ophumayo we-actuator, ukoyisa okuphakathi kwi-spool amandla angalinganiyo. Uxinzelelo lomthombo womoya lufikelela kumandla okukhutshwa kwe-actuator ukunqoba amandla angalinganiyo aphakathi kwi-spool. I-4, kwimidiya yoxinzelelo oluphezulu kule meko ukwenzela ukuthintela ukungena kwe-medium, ukupakisha kuqinile kakhulu, i-friction inkulu, kule meko ukwenzela ukuthintela ukungena kwe-medium, ukupakisha kuqinile kakhulu, ukungqubuzana kukhulu, kwangaxeshanye, amandla angalinganiyo okuphakathi kwi-spool nawo mkhulu, imfuneko yokubeka isixhobo ukoyisa. Amandla angalinganiyo obuninzi kwi-spool nawo makhulu, efuna indawo yokulwa.
