Ukukhethwa Nokuhlaziywa Kwezicelo Zekhethelo (I-Globe Valve) embonini ye-Petrochemical

Ukukhethwa Nokuhlaziywa Kwezicelo Zekhethelo (I-Globe Valve) embonini ye-Petrochemical

Umbono: Njengemboni yensika ebalulekile yomnotho kazwelonke waseShayina, imboni ye-petrochemical idonse ukunakwa okukhulu ngokukhiqiza kwayo okuphephile nokusebenza kahle. Njengesisetshenziswa esibalulekile ezinhlelweni zokulawula uketshezi, ukukhethwa nokusetyenziswa kwamavalvu embulunga kudlala indima ebalulekile ekuqinisekiseni ukusebenza okuphephile nokuzinzile kwezitshalo ze-petrochemical. Lesi sihloko sinikeza ukuhlaziya okujulile kwezimiso zokukhetha, izimo zohlelo lokusebenza, imingcele yezobuchwepheshe, nezixazululo zezingcweti (amavalvu embulunga) embonini ye-petrochemical, okuhloswe ngayo ukunikeza izinkomba ezibalulekile zamabhizinisi e-petrochemical kanye nobunjiniyela obuhlobene nabasebenzi bezobuchwepheshe.

1,Isingeniso

Ngokuthuthuka okusheshayo kwemboni ye-petrochemical yaseChina, isikali semishini siyaqhubeka nokukhula, ukugeleza kwenqubo kuya ngokuya kuba nzima, futhi nezidingo zemishini yokulawula uketshezi ziyanda. Njengengxenye eyisisekelo ezinhlelweni zokulawula uketshezi, ukusebenza kwamavalvu embulunga kuthinta ngokuqondile ukusebenza okuphephile nokuzinzile kwayo yonke idivayisi. Ngakho-ke, emkhakheni wamakhemikhali e-petrochemicals, kubaluleke kakhulu ukukhetha nokusebenzisa (ama-valve embulunga) ngendlela efanele.

2,Izimiso zokukhetha ezikhethekile (ama-valve embulunga) embonini ye-petrochemical

1. Umgomo wokusebenza

Ukukhethwa kwama-valve embulunga kufanele kucabangele ngokugcwele izimo zabo zokusebenza eziqondile embonini ye-petrochemical, okuhlanganisa uhlobo oluphakathi, izinga lokushisa, ukucindezela, njll. Izinhlobo ezahlukene zama-valve embulunga zinezici ezihlukene zesakhiwo kanye nezinzuzo zokusebenza, futhi kufanele zikhethwe ngokuvumelana nezidingo zangempela.

2. Izimiso zokuphepha

Ukuphepha kuwukucatshangelwa okuyinhloko ekukhetheni ama-valve avaliwe embonini ye-petrochemical. Amavalvu eglobhu ahlangabezana namazinga kazwelonke nawemboni futhi anemisebenzi ethembekile yokuvikela ukuphepha kufanele akhethwe ukuze kuqinisekiswe ukusebenza okuphephile kocingo ngaphansi kwezimo zokusebenza ezidlulele.

3. Isimiso sokwethembeka

Enqubweni yokufakwa kwama-valve embulunga embonini ye-petrochemical, adinga ukusebenza kahle kokuvala, ukumelana nokuguga, nokumelana nokugqwala. Lapho kukhethwa, kufanele kuqashelwe izinto ezibonakalayo, inqubo yokukhiqiza, kanye nesithunzi somkhiqizo womkhiqizo ukuze kuqinisekiswe ukusebenza okuzinzile kwesikhathi eside kwemishini.

4. Isimiso sezomnotho

Ngesisekelo sokuhlangabezana nezimiso ezingenhla, umnotho we-valve yokuvala kufanele ucatshangelwe. Ukukhetha okunengqondo kunganciphisa izindleko zokuthengwa kwemishini, izindleko zokusebenza nokugcinwa kwazo, kanye nezingozi zokwehluleka, futhi kuthuthukise izinzuzo zezomnotho zamabhizinisi.

3,Ukuhlaziywa kwezimo zokufakwa kwezicelo ezikhethekile (ama-valve embulunga) embonini ye-petrochemical

1. Imboni yokuhluza uwoyela

Imboni yokuhluza i-petroleum iyingxenye ebalulekile yemboni ye-petrochemical, enenqubo eyinkimbinkimbi yokuhamba kanye nesidingo esikhulu sama-(ama-globe valves). Kulo mkhakha, umfutho ophezulu, izinga lokushisa eliphezulu, kanye nemidiya egqwala kakhulu kuvame kakhulu. Ngakho-ke, ezifanele (ama-valve embulunga) kulezo zimo zokusebenza kufanele kukhethwe, njengokucindezela okuphezulu nokushisa okuphezulu (ama-valve embulunga), ukumelana nokugqwala (ama-valve embulunga), njll.

2. Imboni yamakhemikhali

Imboni yamakhemikhali ibandakanya ukusabela kwamakhemikhali okuhlukahlukene kanye nokwelashwa okuphakathi nendawo, futhi izidingo zokukhetha (amavalvu embulunga) ziqine kakhulu. Ngemidiya yamakhemikhali ehlukene, njenge-asidi, i-alkali, usawoti, njll., izinto ezihambisanayo (ama-valve okuvala) kufanele zikhethwe ukuze kuqinisekiswe ukusebenza okuphephile nokuzinzile kwemishini.

3. Imboni yegesi yemvelo

Isidingo samavalvu okuvala igesi embonini yegesi yemvelo sigxile kakhulu kumapayipi egesi nasezinhlelweni zegesi yasemadolobheni. Lolu hlobo lwesimo sokusebenza ludinga ukuvalwa okuphezulu nokusebenza okunqanda ukuguguleka kwe-(valve yomhlaba), nokusebenza okuphezulu (i-globe valve) kufanele kukhethwe, njengokuvalwa komfutho ophezulu (i-globe valve), i-anti erosion (i-globe valve), njll.

4,Ukuhlaziywa kwepharamitha yezobuchwepheshe kwezikhethekile (i-globe valve) embonini ye-petrochemical

1. Imingcele emaphakathi

Lapho ukhetha i-valve yembulunga, kufanele kuqashelwe imingcele efana nohlobo lwe-medium, izinga lokushisa, nokucindezela. Imidiya ehlukene inezidingo ezihlukene zezinto kanye nesakhiwo (amavalvu embulunga), njengezinga lokushisa eliphezulu, umfutho ophakeme, imidiya egqwalayo, njll.

2. Imingcele yesakhiwo

Imingcele yesakhiwo yevalvu yeglobhu ihlanganisa ububanzi be-valve, uhlobo lwe-valve, indlela yokuxhuma, njll. Uma ukhetha, imingcele yesakhiwo efanele kufanele ikhethwe ngokusekelwe ezidingweni zangempela ukuhlangabezana nezidingo zenqubo yocingo.

3. Imingcele yezinto

Impahla ye-valve yokuvala inomthelela omkhulu ekusebenzeni kanye nempilo yesevisi yemishini. Izinto ezifanele njengensimbi engagqwali kanye nensimbi ye-alloy kufanele zikhethwe ngokusekelwe ezintweni ezifana nezici eziphakathi nendawo, izinga lokushisa, nokucindezela.

5,Izixazululo ezikhethekile (ze-globe valve) zemboni ye-petrochemical

1. Ukwenza kube ngokwakho

Ezimweni ezikhethekile zokusebenza embonini ye-petrochemical, amabhizinisi angahlinzeka ngezinsizakalo zokwenza ngokwezifiso futhi athuthukise (ama-globe valves) ahlangabezana nezimo ezithile zokusebenza ngokwezidingo zamakhasimende.

2. Ukuthuthukiswa okuhlakaniphile

Ngokuthuthukiswa kobuchwepheshe obufana ne-inthanethi Yezinto kanye nedatha enkulu, ukuthuthukisa okuhlakaniphile sekuphenduke inkambiso ekuthuthukisweni kwemishini yokulawula uketshezi. Ukuthuthukiswa okuhlakaniphile kwama-valve embulunga kungathuthukisa ukusebenza kahle kwemishini, kunciphise izindleko zokuyilungisa, futhi kuzuzwe ukuqapha okukude.

3. Ukuhlanganiswa kwesistimu

Ukuhlanganiswa kwesistimu ukuhlanganiswa (ama-valve embulunga) nezinye izinto zokulawula uketshezi, amasistimu okulawula okuzenzakalelayo, njll. ukwenza isisombululo esiphelele. Ukuhlanganiswa kwesistimu kungathuthukisa izinga lokuzenzekelayo ledivayisi futhi kunciphise izindleko zokusebenza.

6,Isiphetho

Ukukhethwa nokusetshenziswa kwamavalvu okuvala akhethekile embonini ye-petrochemical kubalulekile ekuqinisekiseni ukusebenza okuphephile nokuzinzile kwemishini. Lesi sihloko sihlinzeka ngokuhlaziywa okujulile kwezimiso zokukhetha, izimo zohlelo lokusebenza, imingcele yezobuchwepheshe, nezisombululo, ihlinzeka ngereferensi ethile yamabhizinisi kanye nobunjiniyela obuhlobene nabasebenzi bezobuchwepheshe. Ezinhlelweni ezisebenzayo, kuyadingeka ukuthi kucatshangelwe kabanzi izici ezifana nokusebenza komkhiqizo kanye nentengo ngokusekelwe ezimweni ezithile zokusebenza, ukuze kuzuzwe ukukhetha okungcono kakhulu.
