Indlela yokuvavanya uxinzelelo lwevalve yebhola

Uvavanyo lwamandla lwevalve yebhola ye-pneumatic kufuneka luqhutywe phantsi kwemeko yebhola evulekileyo. ① Uvavanyo lokutywina lwevalve yebhola edadayo: beka ivalve kwindawo evulekileyo yesiqingatha, yazisa uvavanyo oluphakathi kwelinye icala kwaye uvale esinye isiphelo; ukujikeleza ibhola ngamaxesha amaninzi, vula isiphelo esivaliweyo xa i-valve ivaliwe ukuba ihlolwe, kwaye ukhangele ukusebenza kokutywinwa kokupakisha kunye ne-gasket ngexesha elifanayo, ngaphandle kokuvuza. Emva koko yazisa i-test medium ukusuka kwelinye icala kwaye uphinde olu vavanyo lungentla. ② Uvavanyo lokutywinwa kwevalve yebhola esisigxina: ngaphambi kovavanyo, jikelezisa ibhola ngamaxesha amaninzi ngaphandle komthwalo, kwaye i-valve yebhola eqingqiweyo ikwimeko evaliweyo. Yazisa indlela yokuvavanya ukusuka kwelinye icala ukuya kwixabiso elichaziweyo; jonga ukusebenza kokutywinwa kwe-lead-in end kunye ne-gauge yoxinzelelo. Ukuchaneka komlinganiselo woxinzelelo ngu-0.5-1, kwaye uluhlu luyi-1.5 amaxesha oxinzelelo lovavanyo. Ukuba akukho nto yokunciphisa uxinzelelo phakathi kwexesha elichaziweyo, ifanelekile; emva koko i-test medium yaziswa ukusuka kwelinye icala, kwaye uvavanyo olungentla luyaphindwa. Emva koko, i-valve ikwimeko evulekileyo evulekileyo, zombini iziphelo zivaliwe, kwaye umngxuma ongaphakathi ugcwele ophakathi. Ngaphantsi koxinzelelo lovavanyo, khangela ukupakisha kunye ne-gasket, kwaye akuyi kubakho ukuvuza. ③ Iivalvu zebhola ezintathu ziyakuvavanywa ukuqina kuzo zonke iindawo.
