Xa kuziwa kwizicelo zoshishino ezifuna ukulawulwa okuthembekileyo, okusebenzayo, iivalve zebhola ezidityanisiweyo zilukhetho oludumileyo. Ezi zivalo zenzelwe ukumelana noxinzelelo oluphezulu kunye neemeko zobushushu obuphezulu, zizenza zilungele amashishini ahlukeneyo kuquka ioli kunye negesi, iikhemikhali zepetroli kunye nokuveliswa kwamandla. Kwesi sikhokelo sibanzi, siza kuphonononga iimpawu, izibonelelo, kunye nokusetyenziswa kweevalvu zebhola ezidityanisiweyo ngokupheleleyo kwaye sibonelele ngokufakela nokugcinwa kwazo.

Iimpawu zevalve yebhola edityanisiweyo ngokupheleleyo

Ivalve yebhola edityaniswe ngokupheleleyo yamkela ulwakhiwo lomzimba wevalve eneqhekeza elinye, kunye nebhola kunye nesiqu sevalve ezidityanisiweyo. Olu yilo luphelisa iindlela ezinokuthi zivuze, zenze ukuba zilungele izicelo apho ukuvuza kungenakuthintelwa. Ulwakhiwo oludityanisiweyo lukwanyusa ukuthembeka kolwakhiwo lwevalvu, luqinisekisa ukuba luyakwazi ukumelana neemeko zokusebenza ezigqithisileyo.

Ezi zivalo zifumaneka kwizinto ezahlukeneyo, kuquka i-carbon steel, insimbi engenasici kunye nentsimbi ye-alloy, ukuze ihambelane neemfuno zenkqubo ezahlukeneyo. Ukongezelela, banokuxhotyiswa ngeendlela ezahlukeneyo zokuhlala kwe-valve kunye nezixhobo zokutywina, ezifana ne-PTFE, igraphite kunye nesinyithi, ukubonelela ngokusebenza okuthembekileyo kokutywinwa kwimidiya eyahlukeneyo kunye nokushisa okusebenzayo.

Izinto ezilungileyo zevalve yebhola edityanisiweyo ngokupheleleyo

Ulwakhiwo oludityanisiweyo lwezi zivalo lubonelela ngeenzuzo ezininzi ngaphezulu kweevalvu zebhola zebholithi. Enye yeenzuzo eziphambili kukutywinwa kwayo okuphezulu, okunciphisa umngcipheko wokukhutshwa kweembacu kunye nokuqinisekisa ukuthotyelwa kokusingqongileyo. Olu phawu lenza iivalvu zebhola ezidityanisiweyo ngokupheleleyo zibe lukhetho olubalaseleyo kwizicelo ezibalulekileyo apho ukhuseleko kunye nokhuseleko lokusingqongileyo lubalulekile.

Ukongezelela, uyilo oluqinileyo lwevalve yebhola edibeneyo edibeneyo kwandisa ukuqina kwayo kunye nobomi benkonzo, ukunciphisa imfuno yokugcinwa rhoqo kunye nokutshintshwa. Oku kunciphisa iindleko zokuphila komsebenzisi wokugqibela kunye nokuphucula ukusebenza kakuhle. Ukongezelela, ezi zivalo ziyakwazi ukuphatha uxinzelelo oluphezulu kunye nobushushu obuphezulu, okwenza ukuba zilungele iimeko zenkqubo efunekayo.

Ukusetyenziswa kwevalve yebhola edityanisiweyo ngokupheleleyo

Iivalve zebhola ezidityanisiweyo zisetyenziswa ngokubanzi kumashishini ahlukeneyo kunye nokusetyenziswa okuvala ngokuthembekileyo kunye nokulawula ukuhamba kwamanzi. Kwicandelo le-oyile negesi, ezi zivalo zisetyenziswa ngokuqhelekileyo kwimibhobho, iitanki zokugcina kunye neendawo zokucubungula ukulawula ukuhamba kweoli ekrwada, igesi yendalo kunye neemveliso ezisulungekileyo. Ukukwazi kwabo ukumelana neendawo zokusebenza ezinzima kunye neenkqubo zoxinzelelo oluphezulu zenza ukuba zilungele ukusetyenziswa kwezicelo eziphezulu, eziphakathi kunye nezantsi.

Ukongeza, iivalve zebhola ezidityanisiweyo ngokupheleleyo zisetyenziswa kakhulu kwizityalo zepetrochemical kunye neekhemikhali kwaye zidlala indima ephambili ekulawuleni ukuhamba kwamanzi amdaka kunye anobungozi. Ulwakhiwo lwabo olumagingxigingxi kunye nesakhono sokutywina sobungqina bokuvuza bubenza balungele ukuphatha imithombo yeendaba eyonakalisayo kunye nokuthintela iingozi ezinokubakho zokhuseleko.

Kwizibonelelo zokuvelisa amandla, iivalve zebhola ezidityanisiweyo ngokupheleleyo zisetyenziswa kwi-steam, amanzi kunye ne-gas systems ukuqinisekisa ukwahlukaniswa okuthembekileyo kunye nokulawulwa kwamanzi kwiibhoyili, ii-turbines kunye nezixhobo ezincedisayo. Ukukwazi kwabo ukusebenza kumaqondo obushushu aphezulu kunye noxinzelelo kubenza babe yinxalenye ebalulekileyo yokusebenza kweplanti yamandla.

Ukufakela kunye nokugcina amanyathelo okhuseleko

Ufakelo olululo kunye nokugcinwa lubalulekile ekuqinisekiseni ukusebenza ngokugqibeleleyo kunye nobomi benkonzo yevalve yakho yebhola edityanisiweyo ngokupheleleyo. Ngexesha lofakelo, kubalulekile ukulandela izikhokelo zomenzi kunye neengcebiso zokuqinisekisa ukuba ivalve ibekwe ngokufanelekileyo kwaye ilungelelaniswe ngaphakathi kwenkqubo yokubhobhoza. Ukongeza, ukuhlolwa rhoqo kunye novavanyo lweevalvu, kubandakanywa ukujonga ukuvuza kunye nokuqinisekisa ukunyaniseka kwetywina, kubalulekile ekuchongeni nasekusombululeni nayiphi na imiba enokubakho.

Imisebenzi yokugcinwa kwesiqhelo, njengokuthambisa isiqu sevalve kunye nokuhlolwa rhoqo kwamacandelo okutywinwa, kunokunceda ukwandisa ubomi benkonzo yevalve yebhola edityanisiweyo ngokupheleleyo. Ukuba kukho naziphi na iingxaki zokusebenza okanye ukuthotywa kokusebenza kwenzeka, ukujongana neengxaki kunye nokulungiswa kufuneka kwenziwe ngokukhawuleza ukuthintela ukuphazamiseka kwenkqubo kunye nokugcina ukunyaniseka kwenkqubo.

Isishwankathelo, iivalvu zebhola ezidityanisiweyo zisisisombululo esithembekileyo, esisebenzayo sokufuna izicelo zamashishini ezifuna ulawulo oluqinileyo kunye nokungavuzi okungavuziyo. Ukusebenza kwayo okungaqhelekanga, ukuqina kunye nokuguquguquka kwenza kube yinto yokuqala yokukhetha iinkqubo ezibalulekileyo kwi-oyile kunye negesi, i-petrochemical kunye namashishini okuvelisa amandla. Ngokuqonda iimpawu, izibonelelo, izicelo kunye nokuqwalaselwa kokugcinwa kweevalve zebhola ezidibeneyo, abasebenzisi bokugqibela banokwenza izigqibo ezinolwazi kwaye bandise ukuthembeka kokusebenza kweenkqubo zabo.
