Kwiimeko eziqhelekileyo, iivalvu zemizi-mveliso azenzi uvavanyo lwamandla xa zisetyenziswa, kodwa emva kokulungisa umzimba wevalvu kunye nesigqubuthelo sevalvu okanye umonakalo wokugqwala komzimba wevalvu kunye nesigqubuthelo sevalvu kufuneka zenze uvavanyo lwamandla. Kwiivalvu zokhuseleko, uxinzelelo lokuseta kunye noxinzelelo lokubuyela kunye nezinye iimvavanyo kufuneka zihambelane nemigaqo efanelekileyo. Ivalvu kufuneka ivavanywe ukuba inamandla kwaye iqine kangakanani ngaphambi kokufakwa. Iivalvu zoxinzelelo oluphakathi noluphezulu kufuneka zihlolwe. Uvavanyo loxinzelelo lwevalvu olusetyenziswa rhoqo ziimithombo zamanzi, ioyile, umoya, umphunga, initrogen, njl. Zonke iintlobo zeevalvu zemizi-mveliso kuquka iivalvu zomoya iindlela zovavanyo loxinzelelo zezi zilandelayo:

1.Ivalvu yebholaindlela yokuvavanya uxinzelelo

Uvavanyo lwamandla evalvu yebhola yomoya kufuneka lwenziwe kwimo yesiqingatha sebhola evulekileyo.

(1)Ibhola edadayouvavanyo lokuqina kwevalvu: ivalvu ivulekile isiqingatha, elinye icala lingeniswa kwindawo yokuvavanya, kwaye elinye icala livaliwe; Jika ibhola izihlandlo ezininzi, vula isiphelo esivaliweyo xa ivalvu ivaliwe, kwaye ujonge ukusebenza kokutywina kwepakeji kunye negasket, kwaye akufuneki kubekho ukuvuza. Emva koko ngenisa indawo yokuvavanya ukusuka kwelinye icala uze uphinde uvavanyo olungasentla.

(2)Ibhala elungisiweyoUvavanyo lokuqina kwevalvu ye-l: ngaphambi kovavanyo, ibhola ijikwa izihlandlo ezininzi ngaphandle komthwalo, kwaye ivalvu yebhola esisigxina ikwimeko yokuvalwa, kwaye i-medium yovavanyo itsalwa ukusuka kwelinye icala ukuya kwixabiso elichaziweyo; I-pressure gauge isetyenziselwa ukujonga ukusebenza kokutywina kwesiphelo sokungena. Ukuchaneka kwe-pressure gauge yi-0.5 ~ 1, kwaye uluhlu lokulinganisa luphindwe ka-1.5 koxinzelelo lovavanyo. Ngexesha elichaziweyo, akukho nto ifanelekileyo yokudakumba; Emva koko ngenisa i-test medium ukusuka kwelinye icala kwaye uphinde uvavanyo olungasentla. Emva koko, ivalvu ivulekile isiqingatha, zombini iziphelo zivaliwe, umngxuma wangaphakathi uzaliswe yimidiya, kwaye ukupakisha kunye ne-gasket zijongwa phantsi koxinzelelo lovavanyo ngaphandle kokuvuza.

(3)Ivalvu yebhola eneendlela ezintathu skufuneka kuvavanywe ukuqina kwemilenze kwiindawo ezahlukeneyo.

2.Ivalvu yokujongaindlela yokuvavanya uxinzelelo

Imeko yovavanyo lwevalvu yokujonga: uhlobo lokuphakamisa ivalvu yokujonga idiski ye-axis ikwindawo ethe tye nethe nkqo; I-axis yetshaneli yevalvu yokujonga i-swing kunye ne-axis yediski ziphantse zangqamana nomgca othe tye.

Ngexesha lovavanyo lwamandla, i-test medium ifakwa kwixabiso elichaziweyo ukusuka kwisiphelo sokungena, elinye icala livaliwe, kwaye umzimba wevalvu kunye nesigqubuthelo sevalvu ziyafaneleka ngaphandle kokuvuza.

Uvavanyo lokutywina luza kungenisa isixhobo sokuvavanya ukusuka kwisiphelo sokuphuma, lujonge umphezulu wokutywina kwisiphelo sokungena, kwaye ukupakisha kunye ne-gasket ziya kufaneleka ukuba akukho kuvuza.
