Ivalve yokhuseleko yivalve esebenza njengesixhobo sokhuseleko kwinkqubo ecinezelekileyo, ithomalalisa uxinzelelo nokuthintela umonakalo, ngamanye amaxesha ide ibulale. Iivalve zokhuseleko zisetyenziselwa izicelo ezahlukeneyo, kubandakanywa iibhoyili zoshishino, imigca ye-steam kunye neenqanawa zoxinzelelo.
Iivalvu zokhuseleko ziyilelwe ukuba zivuleke kwaye zivale ngokuzenzekelayo xa kuthe kwabakho uxinzelelo, kodwa kusenokufuneka ukuba zikwazi ukuvalwa ngesandla xa kusenziwa ugcino lwenkqubo (bona Test-GAG isincedisi).
Incwadi yokusebenza nokugcinwa kwayo luxwebhu olukhapha ivalve ukusukela oko yakhiwe de ibe sisitshixo.ped. Oko kukuthi, yinxalenye yayo. Le ncwadana kufuneka ifundwe phambi kokuba wenziwe nawuphi na umsetyenzana obandakanya isixhobo, kuquka ukusiphatha nokusothula kwindlela yothutho.
Kucetyiswa ukuba abasebenzi bofakelo bayalelwe. Ivalve yokhuseleko kufuneka inikwe inkonzo BESA ngabasebenzi okanye ngabasebenzi abagunyaziswe ngu BESA.
Iivalvu zokhuseleko kufuneka zihlolwe kwaye zivavanywe rhoqo ukuqinisekisa ukusebenza kwazo ngokufanelekileyo. Oku kunokunceda ukukhusela iingozi kunye nokuqinisekisa ukhuseleko lwenkqubo yoxinzelelo. Ukuqinisekisa ukuba i-valve yokukhusela iyakwazi ukwenza umsebenzi wayo ngokuchanekileyo, kubalulekile ukuyihlola kwaye uyigcine rhoqo (Besa icebisa ubuncinci beminyaka emi-2).
Khumbula ukuba ukugcinwa kwevalve yokhuseleko kunokuqhutywa kuphela ngabasebenzi abanobuchule, ngokukhethekileyo abagunyaziswe ngumenzi (njengoko iivalve zokhuseleko azifani zonke, nokuba zenza umsebenzi ofanayo).
Le ncwadana yemigaqo ilandelayo yokuSebenza noLondolozo yinxalenye ebalulekileyo yesivalo sokhuseleko kwaye kufuneka ifumaneke lula kubasebenzi abasebenzayo kunye nololongo.
Umsebenzisi nabasebenzi bolondolozo kufuneka bakwazi okuqulethwe yile ncwadana.
Isatifikethi sovavanyo kunye nomzobo wendibano zibonelelwa ngevalve yokhuseleko. La maxwebhu asetyenziselwa umthengi kuphela kwaye ayipropathi enomgangatho ophezulu wokuqonda we BESA I-SpA apho ulwakhiwo oluphambili kunye neempawu zokusebenza zevalve ezithengiweyo ziboniswa.
Ukususela kwi1946
Endle nawe
BESA ibisenza iivalvu zokhuseleko iminyaka emininzi, kuluhlu olubanzi lofakelo, kwaye amava ethu abonelela ngesona siqinisekiso silungileyo. Sifundisisa ngenyameko each inkqubo ngexesha lesigaba socaphulo, kunye nazo naziphi na iimfuno ezikhethekileyo okanye izicelo, de sifumane isisombululo esona sisombululo kunye neyona valve ifanelekileyo yokufakela kwakho.
