Umgangatho wesizwe flangeivalve yebholainokujikeleza i-90 degrees kwaye ivale ngokuqinileyo nge-torque encinci. Imiqolomba yangaphakathi yevalve ilingana ngokupheleleyo, enika ukuchasana okuncinci kunye nokuhamba ngokuthe tye kwindlela ephakathi. Ivalve yebhola ene-flanged esemgangathweni yesizwe ngokwayo inesakhiwo esihlangeneyo kwaye kulula ukuyisebenzisa kunye nokugcina. Iivalvu zebhola eziphothiweyo zifanelekile kumajelo asebenza ngokubanzi njengamanzi, izinyibilikisi, iiasidi kunye nerhasi yendalo, kunye neendaba ezineemeko zokusebenza ezinzima, njengeoksijini, ihydrogen peroxide, i-methane, kunye ne-ethylene. Umzimba wevalve unokudityaniswa okanye udityaniswe.

Umgangatho wesizwe flangeivalve yebholaixinene ngokwesakhiwo, kulula ukuyisebenzisa kunye nokugcinwa kwayo, ifanelekile kumajelo asebenza ngokubanzi njengamanzi, isinyibilikisi, iasidi kunye negesi yendalo, kwaye ineemeko zokusebenza ezirhabaxa (ezifana nehydrogen peroxide), kwaye ifanelekile nakwimidiya. Imizimba yevalve yebhola efana ne-methane kunye ne-ethylene inokudityaniswa okanye idityaniswe. Iivalvu ezinjalo kufuneka zifakwe ngokuthe tye kumbhobho.

Izinto eziluncedo kumgangatho wesizwe wevalve yebhola eneflanged

1. Ukuxhathisa ulwelo kuncinci, kwaye ivalve yebhola egcweleyo ayinakuchasana nokuhamba.

2. Isakhiwo esilula, ubungakanani obuncinci kunye nobunzima obulula.

3. Vala kwaye uthembekile. Kukho iindawo ezimbini zokutywina. Eyangokuivalve yebholaIzixhobo zomphezulu zokutywina zisetyenziswa ngokubanzi kwiiplastiki ezahlukeneyo, kwaye zinentsebenzo ebalaseleyo yokutywina, enokufikelela ukutywinwa okupheleleyo. Ikwasetyenziswa ngokubanzi kwiinkqubo zevacuum.

4. Ukusebenza ngokufanelekileyo, ukuvulwa ngokukhawuleza kunye nokuvala, kufuneka kuphela ukujikeleza i-90 ° ukusuka ekuvuleni ngokupheleleyo ukuya kuvaliwe ngokupheleleyo, okulungele ukulawula kude.

5. Ukugcinwa ngokufanelekileyo, isakhiwo esilula sevalve yebhola, kunye nendandatho yokutywina ehambayo ngokubanzi, ekulula ukuyichitha kunye nokutshintsha.

6. Xa ivulwe ngokupheleleyo okanye ivalwe ngokupheleleyo, umphezulu wokutywina webhola kunye nesihlalo sevalvu yodwa kuphakathi. Nokuba i-medium iyadlula, umphezulu wokutywina wevalvu awuyi kuhlwa.

7. Ububanzi buvela kwiimilimitha ezininzi ukuya kwiimitha ezininzi, kwaye inoluhlu olubanzi lwezicelo, kwaye ingasetyenziselwa phantsi kwe-vacuum ephezulu ukuya kuxinzelelo oluphezulu.

8. Ngenxa yokuba i-valve yebhola ineempawu zokusula xa ivula kwaye ivala, ingasetyenziselwa imidiya kunye neengqungquthela eziqinileyo.
