Xa ukuthembeka kwenkqubo kunye nokhuseleko kungaxoxiswana ngalo phantsi koxinzelelo olukhulu, ukukhetha ivalvu kuba sisigqibo esibalulekileyo sobunjineli.Iivalvu zeBhola zoXinzelelo oluPhezuluzenzelwe ngokukodwa ukusebenza apho iivalvu ezisemgangathweni zingaphumeleli khona. Esi sikhokelo sijonga ukuba yintoni eyahlula ezi nxalenye ziqinileyo, iimpawu zazo eziphambili zoyilo, kunye nendlela yokukhetha eyona ifanelekileyo kwimisebenzi yakho enzima.
Yintoni iValve yeBhola yoXinzelelo oluPhezulu
A Ivalve yeBhola yoXinzelelo oluPhezuluyivalvu ekhethekileyo yokujika ikota eyenzelwe ukwahlukanisa nokulawula ukuhamba kweendaba ezirhabaxa kwiinkqubo ezisebenza ngaphezulu kwe-10,000 PSI (690 bar). Ngokungafaniyo neevalvu zebhola eziqhelekileyo, zibonakaliswa ngokwakhiwa kwazo okunzima, iindlela zokutywina eziphambili, kunye nezixhobo ezikwaziyo ukumelana noxinzelelo olukhulu loomatshini kunye nobushushu ngaphandle kokubeka emngciphekweni ukusebenza okanye ukhuseleko.
Iimpawu eziphambili zoYilo ezahlula iiValve zeBhola eziXinzelelwa nguMbane
Ukukwazi ukujongana noxinzelelo olugqithisileyo akuyonto nje eyenzeka ngamabona-ndenzile; yimiphumo yobunjineli obucwangcisiweyo nobuchanekileyo. Nazi izinto ezibalulekileyo zoyilo:
Umzimba Oqinisiweyo kunye noKwakhiwa Okuqinileyo:
Ezi valve zihlala zinomzimba omncinci, owenziwe ngezinto ezinamandla aphezulu njengentsimbi engagqwaliyo (SS304, SS316), intsimbi engagqwaliyo ephindwe kabini, okanye intsimbi ye-chromium-molybdenum (A105). I-Forging inika isakhiwo esibalaseleyo sengqolowa, nto leyo ephucula amandla oomatshini bevalvu kunye nokumelana nempembelelo.
Uyilo lweStem yoXinzelelo oluPhezulu:
Isiqu siyaqiniswa ukuze singaphumi phantsi koxinzelelo. Isiqu esomeleleyo, esidla ngokuba noyilo olungenako ukuphumi, siqinisekisa ukuba uxinzelelo lwangaphakathi alunakunyanzela isiqu ukuba siphume emzimbeni wevalvu, uphawu olubalulekileyo lokhuseleko.
Iinkqubo zokutywina eziPhambili:
Le yintliziyo yevalvu yebhola enoxinzelelo oluphezulu.
• Izitulo Ezingashukumi Kakhulu:Kusetyenziswa izihlalo ezenziwe nge-PTFE eqinisiweyo (RPTFE), PEEK (Polyether Ether Ketone), okanye isinyithi. Ezi zinto zigcina ukuqina kwazo kokutywina kwaye azinangxaki ingako ngexesha lokusebenza, nokuba ziphantsi kwamandla aqatha.
• Izihlalo Ezigcwele Intwasahlobo:Iindidi ezininzi zoyilo oluphezulu ziquka izihlalo ezineentwasahlobo. Iispring zisebenzisa amandla angaguqukiyo okuthwala umthwalo kwisihlalo, ukuqinisekisa ukuba ibhola ivalwe ngokuqinileyo xa iphantsi kwaye iphezulu, kwaye ihlawula ukuguguleka ngokuhamba kwexesha.
Izibuko Elincitshisiweyo vs. Izibuko Elipheleleyo:
Nangona iivalvu ezigcweleyo zinika ukumelana nokuhamba kwamanzi okuphantsi, usetyenziso oluphezulu ludla ngokusebenzisa uyilo lwe-reduced-port (okanye i-standard-port). Udonga olutyebileyo olujikeleze i-port encinci luyandisa amandla e-valve okugcina uxinzelelo, nto leyo eyimfuneko ukuze kubekho ukhuseleko oluphezulu.
Usetyenziso olubalulekileyo lweeValve zeBhola eziXinzelelwa nguMbane oPhezulu
Ezi valves zibaluleke kakhulu kumashishini apho ukusilela kwenkqubo kungeyona ndlela ifanelekileyo:
•Ioyile kunye neGesi:Ulawulo lweWellhead, iindibano zomthi weKrismesi, iiyunithi ze-hydraulic fracturing (fracking), kunye neentambo zokuhambisa igesi ezinoxinzelelo oluphezulu.
•Ukuveliswa koMbane:Iintambo eziphambili zomphunga, iinkqubo zamanzi okutya, kunye nezinye iisekethe ezibalulekileyo zoxinzelelo oluphezulu/ubushushu kwizityalo ezishushu nezenyukliya.
•Iikhemikhali kunye neekhemikhali zePetrochemical:Ukuphatha ii-catalysts ezinamandla, ii-reactors ezinoxinzelelo oluphezulu, kunye neenkqubo zokujova.
•Ukusika iJet yamanzi:Ukulawula amanzi anoxinzelelo oluphezulu kakhulu (ukuya kuthi ga kwi-90,000 PSI) asetyenziswa kwiinkqubo zokusika zoshishino.
•IiRig zoVavanyo oluPhezulu:Ukuqinisekisa ukuthembeka kwezinye izinto ezifana nemibhobho, izixhobo, kunye neevalvu.
Indlela yokukhetha iValve yeBhola yoXinzelelo oluPhezulu oluLungileyo
Ukukhetha ivalvu echanekileyo yinkqubo enamacala amaninzi. Cinga ngezi zinto zilandelayo:
1. Uvavanyo loxinzelelo (i-PSI/iBha):
Qinisekisa ukuba uxinzelelo oluphezulu lokusebenza lwevalvu (WP) kunye nomlinganiselo woxinzelelo (umz., i-ANSI Class 1500, 2500, 4500) ludlula uxinzelelo oluphezulu lokusebenza kwenkqubo yakho, kuquka naluphi na uxinzelelo olunokwenzeka lokuphuma kwamandla.
2. Uluhlu lobushushu:
Qinisekisa ukuba isihlalo kunye nezinto zokutywina ziyahambelana namaqondo obushushu aphantsi kunye naphezulu enkqubo yakho.
3. Ukuhambelana kwezinto:
Umzimba wevalvu, i-trim, kunye nezitywini kufuneka zihambelane ne-media (ulwelo okanye igesi) ukuthintela ukugqwala kunye nokuwohloka. Cinga ngezinto ezifana nee-chloride, umxholo we-H2S, kunye namanqanaba e-pH.
4. Ukuphelisa uQhagamshelo:
Khetha kwiintambo eziqinileyo ezifana ne-threaded (NPT), i-socket weld, okanye i-butt weld, ukuqinisekisa ukuba zifanelekile kwishedyuli yombhobho kunye nezinto ezisetyenziswayo.
5. Uyilo Olukhuselekileyo Emlilweni:
Kwizicelo zeoyile negesi, iziqinisekiso ezifana ne-API 607/API 6FA ziqinisekisa ukuba ivalvu iya kuba ne-media xa kutsha.
6. Ukusebenza:
Kwiinkqubo ezizenzekelayo, qinisekisa ukuba ivalvu yenzelwe ukunxibelelana nee-actuators zomoya okanye zombane ezinokuvelisa i-torque eyaneleyo yokusebenza phantsi koxinzelelo olupheleleyo lwenkqubo.
