I-flange esemgangathweni yesizweivalvu yebholaIngajikeleza ii-degrees ezingama-90 ize ivaleke ngokuqinileyo nge-torque encinci. Imingxuma yangaphakathi yevalvu ilingana ngokupheleleyo, nto leyo enika ukumelana okuncinci kunye nendlela ethe tye yokuhamba kwesixhobo. Ivalvu yebhola ejikelezileyo yesizwe ngokwayo inesakhiwo esincinci kwaye kulula ukuyisebenzisa nokuyigcina. Iivalvu zebhola ejikelezileyo zifanelekile kwizixhobo zokusebenza ngokubanzi ezifana namanzi, izinyibilikisi, ii-asidi kunye negesi yendalo, kunye nezixhobo zokusebenza ezinzima, ezifana neoksijini, i-hydrogen peroxide, i-methane, kunye ne-ethylene. Umzimba wevalvu ungadityaniswa okanye udityaniswe.

I-flange esemgangathweni yesizweivalvu yebholaIncinci ngokwesakhiwo, kulula ukuyisebenzisa nokuyigcina ikwimeko entle, ifanelekile kwiindawo zokusebenza ngokubanzi ezifana namanzi, isinyibilikisi, i-asidi kunye negesi yendalo, kwaye ineemeko zokusebenza ezinzima (ezifana ne-hydrogen peroxide), kwaye ikwafanelekile nakwiindawo zokusebenza. Imizimba yeevalvu zebhola ezifana ne-methane kunye ne-ethylene inokudityaniswa okanye idityaniswe. Ezo valve kufuneka zifakwe ngokuthe tye kumbhobho.

Iingenelo zevalvu yebhola ejikelezileyo yesizwe

1. Ukumelana kolwelo kuncinci, kwaye ivalvu yebhola egcwele umngxuma ayinakumelana nokuhamba kwamanzi.

2. Isakhiwo esilula, ubungakanani obuncinci kunye nobunzima obulula.

3. Isondelelene kwaye ithembekile. Kukho iindawo ezimbini zokutywina. Umbane wangokuivalvu yebholaIzixhobo zomphezulu wokutywina zisetyenziswa kakhulu kwiiplastiki ezahlukeneyo, kwaye zisebenza kakuhle kakhulu ekutywineni, nto leyo enokwenza ukuba zitywinwe ngokupheleleyo. Zikwasetyenziswa kakhulu kwiinkqubo zokucoca.

4. Ukusebenza okulula, ukuvula nokuvala ngokukhawuleza, kufuneka ujikeleze kuphela i-90° ukusuka ekuvulekeni ngokupheleleyo ukuya ekuvalekeni ngokupheleleyo, nto leyo ilungele ulawulo olukude.

5. Ulondolozo olulula, ulwakhiwo olulula lwevalvu yebhola, kunye neringi yokutywina enokushukuma ngokubanzi, okulula ukuyiqhaqha nokuyitshintsha.

6. Xa ivuliwe ngokupheleleyo okanye ivaliwe ngokupheleleyo, umphezulu wokutywina webhola kunye nesihlalo sevalvu ziyasuswa kwi-medium. Nokuba i-medium idlula, umphezulu wokutywina ivalvu awuyi kubola.

7. Ububanzi buqala kwiimilimitha ezininzi ukuya kwiimitha ezininzi, kwaye lunoluhlu olubanzi lwezicelo, kwaye lungasetyenziswa phantsi kwe-vacuum ephezulu ukuya kuxinzelelo oluphezulu.

8. Ngenxa yokuba ivalvu yebhola ineempawu zokusula xa ivulwa naxa ivalwa, ingasetyenziselwa imidiya enamasuntswana aqinileyo axhonyiweyo.
