Ukufakwa kunye nokugcinwa kweeValvu zeBhola

Umsebenzi wokulungiselela ngaphambi kokufakwa kweevalvu zebhola

1. Qinisekisa ukuba umbhobho okwindawo yokufakelwa kwevalvu yebhola ukwindawo ye-coaxial, kwaye iiflanges ezimbini kumbhobho kufuneka zigcinwe zihambelana. Qinisekisa ukuba umbhobho unokuthwala ubunzima bevalvu yebhola ngokwawo. Ukuba kufunyaniswe ukuba umbhobho awukwazi ukuthwala ubunzima bevalvu yebhola, xhobisa umbhobho ngezixhobo ezifanelekileyo ngaphambi kokufakwa.
2. Qinisekisa ukuba kukho ukungcola, i-welding slag, njl.njl. kwipayipi, kwaye ipayipi kufuneka icocwe icocekile.
3. Jonga ipleyiti yegama levalvu yebhola, uze uyivule ngokupheleleyo kwaye uyivale ivalvu yebhola izihlandlo ezininzi ukuqinisekisa ukuba ivalvu ingasebenza ngokuqhelekileyo, uze emva koko ujonge zonke iinkcukacha zevalvu ukuqinisekisa ukuba ivalvu ayitshintshanga.
4. Susa izigqubuthelo zokukhusela kuzo zombini iziphelo zevalvu, jonga ukuba umzimba wevalvu ucocekile na, kwaye ucoce umngxuma ongaphakathi womzimba wevalvu. Ekubeni umphezulu wokuvala wevalvu yebhola ungqukuva, nokuba yimfucumfucu encinci inokubangela umonakalo kumphezulu wokuvala.

Sombulula iingxaki zeevalvu zebhola

• ‌Ivalvu inamathele: Xa ivalvu yebhola ingasebenzi ixesha elide okanye isebenza kakubi, ivalvu inokuvinjwa zizinto zangaphandle okanye ukungcola, nto leyo ebangela ukuba ingasebenzi kakuhle. Ngeli xesha, izinto zangaphandle okanye ukungcola kufuneka kuhlolwe kwaye kususwe kuqala. Ukuba ivalvu ibambekile ngenxa yezizathu ezinje ngokuphambuka kwesiqu okanye umphezulu wokuvala ogugileyo, kufuneka kulungiswe okanye kutshintshwe iindawo.
• ‌Ukuvuza: Ukuvuza yenye yeengxaki eziqhelekileyo zeevalvu zebhola kwaye kunokubangelwa zezi zizathu zilandelayo: ‌Ukonakala komphezulu wokutywina‌: Emva kokusetyenziswa ixesha elide, umphezulu wokutywina unokuguga, okubangela ukuvuza. ‌Ukwaluphala kwegasket‌: Igasket iyathamba kwaye ayikwazi ukulingana kakuhle nevalvu. ‌Izibophelelo aziqini‌: Izibophelelo ezifana nezikrufu kunye neenati ziyakhululeka. ‌Ukufakelwa okungafanelekanga‌: Ukufakelwa okungafanelekanga kwevalvu kunokubangela ukuvuza.
• Izisombululo ziquka ukutshintsha umphezulu wokuvala, ukutshintsha i-gasket, ukuqinisa izibophelelo okanye ukufaka kwakhona i-Leakage‌: Izizathu zokuvuza zingabandakanya: ‌Ukwaluphala kwe-gasket‌: I-gasket indala kwaye ithambile. ‌Ukonakala kwe-seal‌: Njengokonakala kwe-O-rings, ukupakisha, njl. ‌Ukuguquka kwebhola‌: Ukuguquka kwebhola kunokubangela ukuvuza.
• Izisombululo ziquka ukutshintsha iigasket, ukutshintsha izitywino, kunye nokutshintsha iibhola ezikhubazekileyo, ‌Amanyathelo okuthintela‌: Hlola kwaye ulondoloze iivalvu zebhola rhoqo ukuqinisekisa ukusebenza kwazo okuqhelekileyo kwaye uphephe ukusilela okubangelwa kukugcinwa okungafanelekanga. Ukutshintshwa kwezitywini ezigugileyo ngexesha elifanelekileyo kunye nokugcinwa okufunekayo kunokunciphisa ngempumelelo ukwenzeka kokusilela. 

Amanyathelo okhuseleko xa usebenzisa iivalvu zebhola

1. Kuphela xa uxinzelelo ngaphambi nasemva kokuba ivalvu yebhola isusiwe apho ivalvu yebhola inokuqhekeka kwaye idityaniswe.
2. Ngexesha lenkqubo yokuqhaqha nokudibanisa kwakhona ivalvu yebhola, kuyimfuneko ukukhusela iindawo zokuvala; ingakumbi iindawo ezingezizo ezesinyithi, ezifana nee-O-rings, njl. Kungcono ukusebenzisa izixhobo ezikhethekileyo.
3. Xa uphinda uhlanganisa umzimba wevalvu yebhola, iibholithi maziqiniswe ngokulinganayo, inyathelo ngenyathelo, kwaye ngokulinganayo.
4. Isixhobo sokucoca kufuneka sihambelane nezixhobo zerabha, izixhobo zeplastiki, izixhobo zesinyithi kunye nezixhobo zokusebenza (ezifana negesi) kwivalvu yebhola.
5. Iindawo eziqhekekileyo zingacocwa ngokuntywiliselwa emanzini. Iindawo zesinyithi ezineendawo ezingezizo ezesinyithi ezingasuswanga zingacocwa ngepompo yerotor eyomileyo kunye nelaphu lesilika elicolekileyo nelicocekileyo elifakwe kwi-arhente yokucoca (ukuthintela ukuchitheka kwefayibha nokunamathela kwiindawo). Xa kucocwa, kufuneka kususwe onke amafutha, ukungcola, iglu, uthuli, njl.njl. anamathele eludongeni.
6. Emva kokucoca, iindawo ezingezizo ezesinyithi kufuneka zisuswe kwisixhobo sokucoca ngoko nangoko kwaye akufuneki zimanziswe ixesha elide.
7. Emva kokucoca, isixhobo sokucoca esikumphezulu wodonga ohlanjiweyo kufuneka sitshiswe (singasulwa ngelaphu lesilika elingafakwanga kwisixhobo sokucoca) ngaphambi kokuba sihlanganiswe, kodwa akufuneki sishiywe ixesha elide, kungenjalo siya kugqwala kwaye singcoliswe luthuli.
8. Iindawo ezintsha nazo mazicocwe ngaphambi kokuba zihlanganiswe.
9. Sebenzisa igrisi ukuze uthambise. Igrisi kufuneka ihambelane nezinto zesinyithi, iindawo zerabha, iindawo zeplastiki kunye nemidiya yokusebenza yevalvu yebhola. Faka umaleko omncinci wegrisi kumphezulu wegroove yokufaka isitywino, umaleko omncinci wegrisi kwisitywino serabha, kunye nomaleko omncinci wegrisi kumphezulu wokuvala kunye nomphezulu wokungqubana kwesiqu sevalvu.
10. Iinkunkuma zesinyithi, ifayibha, kunye negrisi akufanele zivunyelwe ngexesha lokuhlanganiswa 

Isiphelo

Iivalvu zebhola zisetyenziswa kakhulu ekucoceni ioyile, kwiipayipi ezikude, kwiikhemikhali, ekwenzeni amaphepha, kwiimveliso zamayeza, ekugcinweni kwamanzi, kumbane, kulawulo lukamasipala, kwintsimbi nakwamanye amashishini, kwaye zidlala indima ebalulekileyo kuqoqosho lwelizwe. Zinomjikelezo we-90-degree, umzimba weplagi uyinto engqukuva, kwaye kukho umjikelo odlulayo okanye umjelo odlula kwi-axis yawo. Njengomzi-mveliso weevalvu zebhola, i-NSW VALVE iya kuba ngumcebisi wakho ozinikeleyo wokukhetha iivalvu zebhola.
