IValve ye-Huadu-IiValufa eziKhethekileyo zoShishino lwe-Oli

Ushishino lweoyile lubandakanya amakhonkco amathathu aphambili: ukuhlola umlambo, ukuthuthwa komlambo ophakathi, kunye nokucocwa komlambo. Iimeko zokusebenza apha zinzima-uxinzelelo oluphezulu, imithombo yeendaba ezonakalisayo, kunye neemfuno ezingqongqo zokhuseleko-ngoko iivalve eziqhelekileyo aziyi kuyinqumla. Ngokungafaniyo nabaninzi abavelisi abasebenzisa ubungakanani obufanayo-bonke kwi-valve ye-oil industry, sigxininisa kwiintlungu ezizodwa zekhonkco ngalinye. Siyila kwaye senze iivalve ezilungiselelwe imeko nganye, ukuze zisebenze ngokuthembekileyo nangokukhuselekileyo, ngaphandle kwemiba eqhelekileyo ebetha iivalve eziqhelekileyo.

Uluhlu lweeMveliso eziPhambili (NgoMahluko ocacileyo)

1. I-Anti-H₂S ye-High-Pressure Ball Valve (ye-Oilfields ePhezulu)

Le valve yenzelwe ukusetyenziswa kwindawo yeoli enyukayo—ulawulo lwequla, imibhobho yendawo yokomba, nokugqityezelwa kwequla. I-oilfields ine-H₂S kwigesi, edla ngokulula ngeevalvu eziqhelekileyo, ibenza baqhekeke okanye bavuze. Sisebenzisa i-Inconel alloy kumzimba wevalve, ochasene ne-sulfide corrosion, ngoko ayiyi kuphuka nasemva kokudibana kwexesha elide kunye neoli ene-acidic. Ilawula ukuya kuthi ga kwiKlasi ye-2500 yoxinzelelo, isebenza kakuhle ngaphandle kwiimeko ezinomoya okanye ezinothuli, kwaye iqhuba ngokuthe ngcembe ngaphezu kweeyure ezingama-8000. Akukho kulungiswa rhoqo, akukho xesha lokuphumla, ukonga ubunzima kubasebenzi bendawo yeoli.

2. IValve yeSango eNganyangekiyo kubushushu obuphezulu (YeyokuLungisa uMsinga)

Le valve yenzelwe iindawo zokucoca. Ukucokisa kubandakanya amaqondo obushushu aphezulu, kwaye iivalvu eziqhelekileyo ziyajika okanye zivuze ngokulula. Eyethu yenziwe nge-alloy yokumelana nobushushu obuphezulu, akukho deformation nakwi 600℃. Isitulo sevalvu siyakwazi ukunxiba, akukho kuvuza xa uphethe i-oyile yobushushu obuphezulu kunye negesi yombane. Ayifuni ukulungiswa rhoqo, ukonga ixesha kunye nemali yokucoca.

3. Ubushushu obuphantsi butywinweIvalve yeBhola(Uthutho oluphakathi)

Senze le valve ngokukodwa kwi-oyile ephakathi kunye nokuthuthwa kwegesi, ngakumbi kwi-LNG kunye nokuhanjiswa kwe-hydrocarbon ukukhanya. Iivalvu eziqhelekileyo zihlala zijika zibe brittle kwaye zivuze xa zisesichengeni sobushushu obusezantsi kakhulu (ukuya kuthi ga ku -196℃), kodwa le iyisombulula loo ngxaki ngokugqibeleleyo. Sisebenzisa i-316L yensimbi engenasici epholileyo enzulu kumzimba wevalvu-nokuba kubanda kakhulu, ihlala yomelele kwaye ayiyi kwaphuka. Isitywina senziwe ngezinto ezikhethekileyo ze-PTFE ezisezantsi zobushushu, ngoko ke zihlala ziqinile kwaye aziyi kuvuza, kungakhathaliseki ukuba kubanda kangakanani. Siphinde songeze i-valve eyongeziweyo, i-isulated stem ukugcina itywina langaphakathi likhuselwe kubushushu obungaphandle. Ixinene, kulula ukuyifaka, kwaye isebenza kakuhle kuthutho lwemibhobho yomgama omde kunye neemeko ezirhabaxa zangaphandle-akusekho kuxinana okanye imiba yokuvuza.

Izinto eziluncedo ezingundoqo (uMahluko oPhambili)

1. Uyilo oluLungelelweyo oluNxibeleleyo (uMahluko ongundoqo)

Ngokungafani neevalve eziqhelekileyo ezigxininisa kuphela ukutywinwa okusisiseko, sijolise kwiikhonkco ezintathu eziphambili zeshishini leoli: i-oilfield ephezulu (i-anti-H₂S, uxinzelelo oluphezulu), ukuthuthwa kwe-midstream (ubushushu obuphantsi, ukuchasana nokuvuza), kunye nokuhlanjululwa kwezantsi (ukushisa okuphezulu, ukuchasana nokupheka). Imveliso nganye yenzelwe ngokuzimeleyo ngokweemeko zangempela zokusebenza, endaweni yokuguqulwa okuqhelekileyo okuqhelekileyo, okuhambelana ngokwenene neemfuno zangempela zeshishini leoli.

2. UkuTyaniswa kweMathiriyeli yobuNgcali

Asisebenzisi izinto ezifanayo, kodwa izinto ezihambelanayo ngokweemeko ezahlukeneyo: umlambo usebenzisa i-anti-H₂S Inconel alloy, i-midstream isebenzisa i-low-temperature resistant 316L insimbi engenasici, kunye ne-downstream isebenzisa i-alloy ye-high-temperature resistant alloy. Ithintela inkunkuma yezinto kwaye iqinisekisa ukuba i-valve nganye inokuziqhelanisa nendawo yayo yokusebenza ethile, eyingcali ngakumbi kuneevalvu eziqhelekileyo ezisebenzisa into enye kuphela.

3. Uyilo loBuntu noluKhuselekileyo

Zonke iivalve zixhotyiswe ngokhuseleko oluphindwe kabini: i-anti-static, i-anti-explosion kunye ne-anti-overheating designs, ekhusela iingozi zokhuseleko ezifana nokuvuza kunye nomlilo obangelwa uxinzelelo oluphezulu, ukushisa okuphezulu kunye neendaba ezinokutsha. Ngexesha elifanayo, ngokweempawu zangaphandle kunye nemibhobho yoshishino lweoli, isakhiwo se-valve siphuculwe ukuba sibe lula ukuyifaka nokugcina, ukunciphisa ubunzima bokusebenza kwisayithi.
