Ukuhlaziywa Kokusebenza Kwe-American Standard Cast Steel Globe Valves ngaphansi Kwezimo Zokusebenza Ezidlulele

Abstract: Njengengxenye ebalulekile yamapayipi ezimboni, ukuzinza nokuthembeka kwamavalvu eglobhu ensimbi ajwayelekile yaseMelika kunomthelela omkhulu ekusebenzeni kwalo lonke uhlelo. Le ndatshana ihlaziya ukusebenza kwamavalvu eglobhu ensimbi ajwayelekile aseMelika ngaphansi kwezimo zokusebenza ezidlulele, ukuhlola izinto zokwakha, izakhiwo, izinhlelo zokusebenza, nezinye izici ukuze kunikezwe ireferensi yokuklama nokugcinwa kobunjiniyela.

1, Isingeniso

Ngokuthuthuka kobuchwepheshe bokukhiqiza ezimbonini, izimboni eziningi zenze izidingo eziphezulu zezinhlelo zamapayipi. Ngaphansi kwezimo ezimbi kakhulu ezifana nezinga lokushisa eliphezulu, umfutho ophezulu, kanye nokugqwala, ukusebenza kwamavalvu eglobhu ensimbi ajwayelekile yaseMelika sekugxile kakhulu kobunjiniyela kanye nabasebenzi bezobuchwepheshe. Njenge-valve yamapayipi evamile, ivalvu yeglobu yensimbi evamile yaseMelika inezinzuzo zesakhiwo esilula, ukusebenza kahle kokuvala, nempilo ende yesevisi. Kodwa-ke, ngaphansi kwezimo zokusebenza ezimbi kakhulu, ukusebenza kwama-valve e-globe yensimbi yensimbi ejwayelekile yaseMelika kuzothinteka kakhulu, futhi indlela yokuqinisekisa ukuthi ukusebenza kwabo okuzinzile ngaphansi kwalezi zimo sekuyinkinga ephuthumayo okufanele ixazululwe.

2, Ukuhlaziywa Kwezinto Zokusebenza Kwe-American Standard Cast Steel Globe Valves

1. Insimbi yensimbi

Izingxenye eziyinhloko ze-valve yeglobu yensimbi evamile yaseMelika, njengomzimba we-valve, isembozo se-valve, ne-valve disc, zenziwe ngezinto ezisansimbi. Insimbi ye-Cast inomshini omuhle, wokulingisa, kanye nezakhiwo zokushisela, okuyenza ifaneleke ukukhiqiza ama-valve anomumo oyinkimbinkimbi, izidingo zamandla aphezulu, nokumelana nokucindezela okuhle. Ngaphansi kwezimo zokusebenza ezidlulele, izakhiwo zemishini kanye nokumelana nokugqwala kwezinto ezisetshenziswayo zensimbi kunomthelela omkhulu ekusebenzeni kwamavalvu eglobhu ensimbi ajwayelekile yaseMelika.

2. Isihlalo se-valve kanye nezinto zokuvala

Ukusebenza kokubekwa uphawu kwamavalvu eglobhu ensimbi ajwayelekile aseMelika kuncike esihlalweni sevalvu nezinto zokuvala. Ezimweni ezinzima zokusebenza, izinto zokuvala zidinga ukumelana nokushisa okuhle, ukumelana nokucindezela, nokumelana nokugqwala. Njengamanje, izinto zokuvala ezivame ukusetshenziswa zifaka iraba, i-polytetrafluoroethylene (PTFE), insimbi, njll. Ukukhetha izinto ezifanele zokuvala kungathuthukisa ukusebenza kokuvala kwamavalvu eglobhu ensimbi ajwayelekile yaseMelika ngaphansi kwezimo zokusebenza ezidlulele.

3, Ukwenziwa kahle kwesakhiwo kwamavalvu eglobhu ensimbi ajwayelekile aseMelika

1. Isakhiwo somzimba we-valve

Ukuze uvumelane nezimo zokusebenza ezidlulele, ukwakheka komzimba we-valve yamavalvu eglobhu ensimbi ajwayelekile yaseMelika kufanele kuthuthukiswe. Ngokwamukela umklamo ohlelekile, ukumelana noketshezi kuyancishiswa, umthelela woketshezi uyancishiswa, ngaleyo ndlela kunciphisa ukudlidliza kwe-valve nomsindo. Ukwengeza, ukukhulisa ukushuba komzimba we-valve kanye nokwenza ngcono amandla nokuqina komzimba we-valve kungasiza ekuthuthukiseni ukusebenza kokuqina kwama-valve eglobhu ensimbi ajwayelekile yaseMelika ngaphansi kwezimo zokusebenza ezinzima.

2. Isakhiwo se-valve disc

Isakhiwo sediski samavalvu eglobhu ensimbi ajwayelekile yaseMelika sinomthelela omkhulu ekusebenzeni kokuvala nokusebenza kokugeleza. Ukusetshenziswa kwama-valve discs ayindilinga kungathuthukisa ukulingana kwendawo yokuvala futhi kunciphise izinga lokuvuza. Ngasikhathi sinye, ukwenza kahle ukuma kwendawo yokuvala ye-valve disc kanye nesihlalo se-valve ukwakha ijethi yoketshezi enesivinini esikhulu ngesikhathi sokudlula kusiza ukusula indawo yokuvala futhi kunciphise ukuguga.

3. Shayela idivayisi

Idivayisi yokushayela yevalvu yeglobu yensimbi evamile yaseMelika inomthelela omkhulu ekusebenzeni nasekuzinzeni kwevalvu. Ezimweni ezinzima zokusebenza, imishini yokushayela efanelekile kufanele ikhethwe, njengogesi, i-pneumatic, i-hydraulic, njll. Ngesikhathi esifanayo, idivayisi yokushayela kufanele ibe nokusebenza okuhle kokuvikela ukuvimbela izici zemvelo ukuthi zingathinti ukusebenza kwamavalvu.

4, Ukusetshenziswa kwamavalvu eglobhu ensimbi ajwayelekile aseMelika ezimeni zokusebenza ngokwedlulele

1. Izimo zokusebenza eziphezulu zokushisa

Ngaphansi kwezimo zokushisa eziphakeme, ukusebenza kokuvala nokusebenza kwemishini kwamavalvu eglobhu ensimbi ajwayelekile yaseMelika kuzothinteka kakhulu. Ukuqinisekisa ukusebenza kwayo ngaphansi kwezimo eziphakeme zokushisa, izinto zokwakha kanye nezinto zokubeka uphawu ezinokumelana okuhle kokushisa okuphezulu kufanele kukhethwe. Ngesikhathi esifanayo, ukwelashwa kokupholisa kwenziwa emzimbeni we-valve, i-valve disc nezinye izingxenye zokunciphisa izinga lokushisa lokusebenza nokuthuthukisa impilo yesevisi ye-valve.

2. Izimo zokusebenza ezinengcindezi ephezulu

Amandla nokusebenza kokuvala kwamavalvu embulunga yensimbi ajwayelekile aseMelika kubalulekile ngaphansi kwezimo ezinomfutho ophezulu. Amandla aphezulu kanye nezinto zokuqina okuphezulu kufanele kukhethwe ukuze kuthuthukiswe ukumelana nokucindezela kwe-valve. Ngaphezu kwalokho, thuthukisa ukwakheka kwe-valve, unciphise ukumelana noketshezi, futhi uvimbele ukudlidliza kwe-valve okubangelwa ukushintshashintsha kwengcindezi.

3. Izimo zokugqwala

Ngaphansi kwezimo zokugqwala, izinto ezibonakalayo nezinto zokuvala zamavalvu eglobhu ensimbi ajwayelekile yaseMelika kufanele kube nokungagqwali okuhle. Ukusebenzisa izinto ezimelana nokugqwala njengensimbi engagqwali nama-alloys asekelwe ku-nickel ukuze kuthuthukiswe impilo yesevisi yamavalvu ezindaweni ezigqwalile. Ngesikhathi esifanayo, khetha izinto zokuvala ezinokumelana nokugqwala okuhle ukuze unciphise izinga lokuvuza.

5. Isiphetho

Le ndatshana ihlaziya ukusebenza kwamavalvu eglobhu ensimbi ajwayelekile aseMelika ngaphansi kwezimo zokusebenza ezidlulele, futhi iphakamisa izinyathelo zokuthuthukisa ezicini zempahla, ukwakheka, nokusetshenziswa. Ekwakheni nasekugcinweni kobunjiniyela kwangempela, izinto ezifanele, izinto zokuvala, kanye nemishini yokushayela kufanele kukhethwe ngokusekelwe ezimeni ezithile zokusebenza, ukwakheka kwamavalvu kufanele kuthuthukiswe, futhi ukuzinza kokusebenza kwamavalvu eglobhu ensimbi ajwayelekile yaseMelika kufanele kuthuthukiswe ngaphansi kwezimo zokusebenza ezidlulele. Lokhu kuzohlinzeka ngeziqinisekiso eziqinile zokusebenza okuphephile nezinzile kohlelo lwamapayipi ezimboni zaseChina.
