Kwiinkqubo zoshishino, ukushisa okuphezulu kunye neendawo zoxinzelelo oluphezulu ziimeko eziqhelekileyo.Ukusuka kwioyile kunye negesi ukuya kumashishini ekhemikhali kunye nepetrochemical, imfuno yeevalvu ezithembekileyo, ezisebenzayo ezinokumelana neemeko ezinzima zibalulekile.Kulapho izinga lokushisa eliphezulu kunye neevalve eziphakamileyo zidlala kwaye ziyingxenye ebalulekileyo yokuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwemisebenzi eyahlukeneyo yezoshishino.
Ukushisa okuphezulu kunye noxinzelelo oluphezulu lwe-valve zenzelwe ngokukodwa ukujongana neemeko ezinzima ezifumaneka kumashishini apho amaqondo okushisa aphezulu kunye noxinzelelo zizinto eziqhubekayo.Ezi zivalo zenzelwe ukujamelana nobunzima bolu hlobo lokusingqongileyo, ukubonelela ngokusebenza okuthembekileyo kunye nokuqinisekisa ukunyaniseka kwenkqubo yonke.
Enye yezinto eziphambili ezahlula i-high-temperature kunye ne-high-pressure valves ukusuka kwii-valve eziqhelekileyo kukukwazi ukujamelana neemeko ezinzima ngaphandle kokuchaphazela ukusebenza kwazo.Ezi zivalo zenziwe ngezinto ezichasene nokushisa okuphezulu kunye noxinzelelo, njengensimbi engenasici, insimbi ye-alloy kunye nezinye ii-alloys ezizodwa.Oku kuqinisekisa ukuba i-valve igcina ingqibelelo yayo yesakhiwo kunye nokusebenza nangona ibonakaliswe kumaqondo aphezulu kunye noxinzelelo.
Ukongeza kulwakhiwo olomeleleyo, ubushushu obuphezulu kunye neevalvu zoxinzelelo oluphezulu zenzelwe iindlela zokutywina eziphambili ukuthintela ukuvuza kunye nokuqinisekisa ukuvalwa okuqinileyo.Oku kubalulekile kwishishini apho naluphi na uhlobo lokuvuza lunokuba neziphumo ezibi.Ezi zivalo zigcina isitywina esikhuselekileyo naphantsi kweemeko ezinzima, ezibaluleke kakhulu kukhuseleko kunye nokuthembeka kwenkqubo yonke.
Ukongezelela, i-valve ephezulu yokushisa kunye ne-high-pressure valves ihlala ihamba kunye neempawu ezifana neebhonethi ezongeziweyo kunye nokupakishwa okukhethekileyo ukubonelela ngokhuseleko olongezelelweyo kwiimeko zokusebenza ezinzima.Ezi mpawu zinceda ukunciphisa imiphumo yokushisa okuphezulu kunye noxinzelelo kumacandelo e-valve, ukwandisa ubomi babo benkonzo kunye nokunciphisa imfuno yokugcinwa rhoqo kunye nokutshintshwa.
Iivalve ezinobushushu obuphezulu kunye noxinzelelo oluphezulu zisetyenziswa kwiinkqubo ezahlukeneyo, ukusuka kwiinkqubo ze-steam kunye nezityalo zebhoyila ukuya kwiinkqubo zokucoca kunye nezixhobo zokuvelisa amandla.Ngokomzekelo, kwiinkqubo ze-steam, ukushisa okuphezulu kunye noxinzelelo oluphezulu ludlala indima ebalulekileyo ekulawuleni ukuhamba kwe-steam kunye noxinzelelo kunye nokuqinisekisa ukusebenza ngokufanelekileyo nangokukhuselekileyo.Ngokufanayo, ngexesha lenkqubo yokucoca, ezi zivalo zisetyenziselwa ukulawula ukuhamba kobushushu obuphezulu kunye noxinzelelo oluphezulu, kunceda ukuphucula ukusebenza kakuhle komsebenzi wokucoca.
Kwishishini le-oyile kunye negesi, i-high-temperature kunye ne-high-pressure valves zibalulekile ekulawuleni ukuhamba kwee-hydrocarbons kunye nolunye ulwelo kwii-wellheads, iipayipi kunye nezixhobo zokusebenza.Ukukwazi kwezi zivalo ukumelana neemeko ezinzima ezifunyenwe kwimisebenzi yeoli kunye negesi kubalulekile ekuqinisekiseni ukhuseleko kunye nokuthembeka kweziseko zophuhliso.
Ukongezelela, kwiikhemikhali kunye nezityalo ze-petrochemical, i-high-temperature kunye ne-high-pressure valves ziyingxenye ebalulekileyo yokuphatha kunye nokucubungula i-corrosive and high-temperature fluids.Ezi zivalo zenzelwe ukuxhathisa imiphumo ephazamisayo yeekhemikhali kunye nokugcina ukusebenza kwazo phantsi kweemeko ezinzima ezixhaphake kwiindawo ezinjalo.
Isishwankathelo, ukushisa okuphezulu kunye neevalve zoxinzelelo oluphezulu zizinto ezibalulekileyo kwizicelo zoshishino apho iimeko ezinzima zingumngeni oqhubekayo.Ukukwazi kwabo ukumelana nokushisa okuphezulu kunye noxinzelelo, ukugcina ukuvalwa okuqinileyo, kunye nokubonelela ngokusebenza okuthembekileyo kwenza ukuba kubaluleke kakhulu ekuqinisekiseni ukhuseleko kunye nokusebenza kakuhle kweenkqubo ezahlukeneyo zoshishino.Njengoko ishishini liqhubeka nokutyhala imida yeemeko zokusebenza, imfuno yobushushu obuphezulu kunye ne-high-pressure valves iya kuqhubeka ikhula kuphela, igxininisa ukubaluleka kwabo kubunjineli bezoshishino kunye nokhuseleko.
