Ngenxa yokuthi i-valve yesiteshi samandla idlala indima engenakushintshwa kulo lonke uhlelo lwamandla, kuyadingeka ukukhetha i-valve enekhwalithi ephezulu nokusebenza okuzinzile. Kodwa-ke, ekusetshenzisweni kwangempela kwenqubo ye-valve, kusenezinkinga eziningi kanye nokukhubazeka kwe-valve yesiteshi samandla, amazinga ekhwalithi ye-valve awahlangabezani nezidingo zezindinganiso ezifanele kanye nokucaciswa, ukukhiqizwa kwe-valve ukuntuleka kwesayensi nokuthembekile, amandla. Isistimu yokulawula i-valve yesiteshi nayo inamaphutha athile. Ukuba khona kwalezi zinkinga kuvimbela kakhulu ukusetshenziswa kwamavalvu eziteshi zikagesi, ngaleyo ndlela kuvimbe intuthuko yesikhathi eside nethembekile yemboni kagesi. ? Ukulimala kweSango lesango kuyingxenye ebalulekile ye-valve yesango, ngakho-ke, ukuze wenze indima ye-valve yesango ukuze uthole ukudlala okuphumelelayo, kuyadingeka ukunamathisela ukubaluleka okukhulu ekubekweni uphawu kwayo, nasekukhiqizeni noma ekugcinweni kwezingxenye ezibalulekile. . Enqubweni yokusebenzisa inqama, amandla atholakala ikakhulukazi emandleni okuqina namandla okucindezela, ngaphezu kwalokho, kukhona ukuguguleka nomthelela obangelwa uketshezi. Kundawo yokuvala, amandla e-extrusion namandla okushayisana yingcindezi. Ukucindezela kwesango ukucindezelwa okusalayo kanye nokucindezela okumile, lapho ukucindezeleka okusalayo kuthinteka yizici zokukhiqiza, ukucindezela okumile kuthintwa isihlalo se-valve kanye noketshezi. Ngokusho kokuhlaziywa kwamandla, ukuhlukahluka nobunkimbinkimbi yizici zenqama, futhi inqama izolimala lapho ibhekene nomthwalo osindayo wangaphandle. Ngesikhathi esifanayo, ngaphansi kwethonya lawo wonke amandla, uketshezi luyaqiniswa, bese lugqwala umzimba wophawu lwesango, lunciphisa uphawu lwesango, oluholela ekulimaleni kwesango. Ukuhluleka kwesistimu Engozini ye-valve, ngenxa yokwehluleka kwesistimu yokulawula ama-valve okubangelwa izingozi ezinkulu kubalele ingxenye enkulu. Ngokucwaninga nokuhlaziya, ukwehluleka kwesistimu, ikakhulukazi ngenxa yokuntuleka kokucabangela kanye nomklamo wesayensi wokuvulwa kwe-valve, isakhiwo sokudlulisa asiguquki ngokwanele, futhi ukushaywa komzimba akukona okunembile nokunye, lezi yizici eziqondile ezithinta ukwehluleka kwesistimu yokulawula i-valve. , ikakhulukazi umthelela wokudlidliza namandla ayo ubonakala ikakhulukazi. Umklamo wokuvula i-valve uhlobene eduze nokuthuthukiswa okuhlelekile kokukhiqiza, futhi ukunakwa okukhethekile kufanele kukhokhwe kuwo. Njengamanje, ucwaningo lokuvula luya ngokuya lubucayi, futhi kancane kancane luba yinkinga enkulu yocwaningo. Emshinini wokudlulisa, ngokuthuthuka okuqhubekayo kanye nokusha kwesayensi nobuchwepheshe, ivalvu ehlakaniphile ibekwa phambili. Ingakwazi ukubona ingxenye yayo yesigamu ngokwezimo zokusebenza ezihlukene, futhi inomsebenzi wokuzilawula kanye nezici zesikhathi sangempela, okuqinisekisa ukuguquguquka kwe-valve ngezinga elikhulu. I-Digital positioner ingxenye yokuqala ye-valve ehlakaniphile, ngosizo lwe-microprocessor, ithuthukisa ukunemba kokuma kwe-valve actuator, kanye nokuqapha nokurekhoda idatha ehlobene ne-valve. Umbuzo wamandla Amandla nempilo yesevisi ye-valve inqunywa inani lezikhathi lapho iyunithi iqala khona, futhi ukulawulwa kwesivinini se-valve kuyithonya eliqondile kakhulu. Ukuze wenze i-valve isebenze, kuyadingeka ukugxila emandleni, ukuqina kanye nempilo yesevisi ye-valve ukuqinisekisa. Ngokuvamile, uma iyunithi ivame ukuqaliswa, i-valve ngeke ikwazi ukuhlangabezana nezidingo zangempela zokusebenza, okubangelwa ikakhulukazi amandla anganele we-valve. Ekwakhiweni kwe-valve, okumele kusekelwe emthwalweni oyisisekelo, ekwakhiweni okusemthethweni, qaphela kuphela izinga lokushisa, ingcindezi emile kanye nokukhasa kanye nezinye izici ezithonyayo, akuzange kucabangele inkinga yokuphila kokukhathala, okuholela ekwakhiweni kwe-valve. ayikwazi ukuhlangabezana nezidingo zangempela zohlelo lokusebenza. Ngakho-ke, isici sokuphila sokukhathala kufanele sicatshangelwe ekuklanyeni ukuze kuqinisekiswe ukuthi isimo sokuklama sihambisana nesimo sokusebenza, ukuze kwandiswe impilo yesevisi ye-valve. Ngenxa yezinkinga ezithile kanye nokukhubazeka okukhona kuvalvu yesiteshi sikagesi, izisebenzi ezifanele zenze ucwaningo olujulile nokuhlaziya, futhi zabeka phambili izinyathelo zokulungisa ezihambisanayo. Ngesikhathi esifanayo, kuxoxiwe ngenqubo yevalvu yesiteshi sikagesi, okube negalelo elikhulu ekuqinisekiseni ukusetshenziswa ngempumelelo kwevalvu yesiteshi sikagesi. Isu lokulungisa Ukuze kuqinisekiswe ukwethembeka nokuphepha kwe-valve yesiteshi samandla ohlelweni lokusebenza, kufanele igcinwe njalo ukuze kuqinisekiswe ukusebenza okuvamile kwe-valve yesiteshi samandla ngaso sonke isikhathi. Ngokuhlaziya nokucwaninga kwabasebenzi abafanelekile, indlela yokufaka i-valve ifinyezwa, okungukuthi, ukusebenza okuphephile nokugcinwa lula, kuphela ukufeza lezi zindinganiso ezimbili, ukuqinisekisa ukusebenza kahle kwe-valve yokusetshenziswa, ukuze kuqinisekiswe ukuthi i-valve inempilo futhi iphephile. ukuthuthukiswa okuphephile kwemboni yamandla. Ucwaningo lwenkinga Ngokusho kokuhlaziywa kwenqubo yokusetshenziswa kwangempela kwe-valve yesitshalo samandla, izinkinga eziyinhloko ekulawuleni, amandla, nokudlidliza yi-valve. Ngokulandisa okungenhla okungaziwa, izinkinga ze-valve esiteshini samandla ezikhona ezinhlobonhlobo nobunkimbinkimbi, kodwa ukufana kwazo, izimbangela zokwakheka kwalezi zinkinga ukuze kubhekwane nalezi zinkinga, izici ezithonya zabasebenzi abafanelekile be-valve yesiteshi samandla * * * kanye nokuhlaziywa kwesistimu, khona-ke ingqikithi yezinkinga ze-valve inokuqonda nokuphatha. Phakathi kwazo, izici zamandla, ezimile, eziguquguqukayo, zokugqoka kanye nokuzinza ziyafundwa. Ukuqapha i-valve Kulesi sigaba ukuze kuxazululwe inkinga ye-valve, ukuthuthukiswa kohlelo lokulawula ama-valve kanye nokuxilongwa kwephutha ngesikhathi sangempela phesheya kuye kwagxilwa kukho, kulo mongo, ngoba abakhiqizi bamavalvu balethe izinzuzo ezinkulu kwezomnotho, ukuze ukukhuthaza ukuthuthukiswa okusheshayo kwezimboni ezihlobene. Ngokuthuthukiswa okuqhubekayo kobuchwepheshe bolwazi lwe-elekthronikhi, imboni yamandla kagesi yezwe lethu isebenzisa ngenkuthalo ubuchwepheshe obuphambili bokuqapha ku-inthanethi, futhi isimo sokusetshenziswa kwama-valve siqapha ngamandla ngesikhathi sangempela, ngaleyo ndlela sithola idatha yokusebenza yama-valve. Ngesikhathi esifanayo, ukusebenza kwe-valve kuyathuthukiswa, izikhathi zokugcinwa kwe-valve ziyancipha, izindleko zokulondoloza zigcinwa, futhi inzuzo yezomnotho iyathuthukiswa. Kungashiwo ukuthi ukuqapha okunamandla kwe-inthanethi kwama-valve kuye kwabeka isisekelo esiqinile sokuthuthukiswa okusheshayo kwemboni yama-valve, ukuze kuhlale kuhambisana nezinga lobuchwepheshe lamazwe ngamazwe. Ukuhlaziywa kobuchwepheshe I-valve yesiteshi samandla ibonakala ngokuyinhloko ukunyakaza kwe-valve disc, futhi ukunyakaza kunezinhlobo ezahlukene, ngesikhathi esifanayo, ukuvulwa kwe-valve stem nokuvala kune-stroke emfushane, ngakho ukwethembeka kokusika kuphezulu. I-disc ye-valve ye-globe yenziwe ngensimbi ekhonjiwe noma insimbi eyenziwe. Lapho i-disc ivuliwe, isihlalo se-valve kanye ne-surface yokuvala ye-disc izohlukaniswa, ukuze ukugqokwa komshini kwendawo yokuvala kube kuncane futhi indawo yokuvala ibe nempahla enhle yokuvala. Kodwa-ke, ukungalungi kwendawo yokubeka uphawu ukunamathela kwezinhlayiya, futhi i-valve disc idinga ukwenziwa ibhola le-porcelain noma ibhola lensimbi. Ngokuvamile, i-disc nesihlalo ku-valve yembulunga kulula ukuyishintsha futhi igcinwe, futhi i-valve nepayipi kungashiselwa ucezu olulodwa ngaphandle kokuhlakazeka kwayo yonke i-valve.
