I-Trunnion vs I-Floating Ball Valve: Yikuphi Okufanele Isicelo Sakho

Kukhona umehluko omkhulu phakathiAmavalvu ebhola le-trunnionfuthiAmavalvu ebhola antantayongokwesakhiwo, isimiso sokusebenza, ukusebenza kanye nezikhathi zokusetshenziswa. Okulandelayo ukuqhathanisa okuningiliziwe kwalokhu okubili:

Umehluko Wesakhiwo se-Trunnion kanye ne-Floating Ball Valve

I-Trunnion Ball Valve

• Ibhola lixhunywe ngokuqinile eziqwini zevalvu eziphezulu nezingezansi. Ibhola lingazungeza kuphela i-axis yesiqu sevalvu futhi alikwazi ukuhamba ngokukhululeka emzimbeni wevalvu.
• Iziqu zevalvu ephezulu nengezansi zixhunywe ngokuqinile ebholeni, okuvimbela ndawonye ukunyakaza kwebhola.

I-Floating Ball Valve

• Ibhola liyantanta, okungukuthi, akukho ukuxhumana okuqinile phakathi kwebhola nesihlalo sevalvu, futhi ibhola lingahamba ngokukhululeka emzimbeni wevalvu.
• Ngokuvamile isiqu se-valve esingezansi esisodwa kuphela sixhunywe ebholeni, kanti isiqu se-valve esiphezulu ngokuvamile sidlala indima yokudlulisa i-torque futhi asigxili ngqo ebholeni.

Isimiso Sokusebenza

1. I-valve yebhola le-trunnion

• Ukulingana okuqinile kanye nokuvala phakathi kwebhola kanye nesihlalo sevalvu kufezwa ngokulayisha kuqala phakathi kwebhola kanye nesihlalo sevalvu kanye nokudluliselwa kwesiqu sevalvu.
• I-torque idluliselwa ngokulinganayo ebholeni ngeziqu zevalvu ephezulu nengezansi, futhi ukujikeleza kwebhola kubushelelezi futhi amandla alingana kakhulu.

2. I-valve yebhola entantayo

• Uma ivaliwe, ingcindezi ephakathi nendawo isunduzela ibhola esihlalweni se-valve yokuphuma, ukuze ibhola kanye nesihlalo se-valve kulingane kahle ukuze kufezwe ukuvalwa. Uma ingcindezi ephakathi nendawo inkulu, kulapho umphumela wokuvala uba ngcono khona.
• I-torque idluliselwa kakhulu ebholeni ngesiqu se-valve esingezansi, kanti isiqu se-valve esiphezulu sisiza ekudlulisweni. Ngesikhathi senqubo yokuvula nokuvala, isimo samandla ebhola siyinkimbinkimbi kakhulu.

Izici Zokusebenza

1. I-valve yebhola le-trunnion

• Ukusebenza kokuvala okuzinzile, okungathinteki ukushintshashintsha kwengcindezi okuphakathi.
• Isakhiwo siyinkimbinkimbi kakhulu, ukubukeka kwayo yonke into kuqinile kancane, futhi umzimba wevalvu uvame ukuba mkhulu.
• Ifanele izinhlelo zamapayipi ezinomfutho ophezulu, ezinobubanzi obukhulu, kanye nezikhathi ezinezidingo eziphezulu zokusebenza kokuvala nokulawula ukugeleza.

2. I-valve yebhola entantayo

• Uma ingcindezi ephakathi iphansi noma kungekho ingcindezi ephakathi, ukusebenza kokuvala kungathinteka ngezinga elithile.
• Isakhiwo sisonke silula, ukubukeka kuncane, futhi ivolumu ivame ukuba ncane.
• Isetshenziswa kakhulu ezinhlelweni zamapayipi ezinomfutho ophakathi nophansi, ezinobubanzi obuncane, kanye nezikhathi ezinezidingo eziphezulu zokuhlanzeka okuphakathi kanye nomfutho ophakathi ozinzile.

Izicelo

1. I-valve yebhola le-trunnion

Ifaneleka kakhulu ngezikhathi zokucindezela okuphezulu, ezinobubanzi obukhulu, njengezinhlelo ezibalulekile zamapayipi kumakhemikhali kaphethiloli, ukudluliswa kwegesi yemvelo, ugesi kanye neminye imboni.

Kufanelekela izikhathi ezidinga ukuvalwa okubili, ngoba ukwakheka kwesihlalo sevalvu yevalvu yebhola egxilile kungaqinisekisa ukuvalwa kuzo zombili izinhlangothi.

2. I-valve yebhola entantayo

Isetshenziswa kabanzi ezimbonini zamakhemikhali, uphethiloli, igesi yemvelo kanye nezinsimbi, ikakhulukazi kumapayipi egesi yemvelo aqhelelene aqukethe imidiya ye-hydrogen sulfide, ukungcola noma ukugqwala okukhulu.

Futhi kufanelekile ngezikhathi lapho kunezidingo eziphezulu zokuhlanzeka okuphakathi kanye nomfutho ophakathi ozinzile, njengezinhlelo zamanzi ezivamile kanye nezinhlelo zokukhipha amanzi, izinhlelo zokupholisa umoya, njll.

Ngokufigqiwe

Amavalvu ebhola le-trunnion namavalvu ebhola antantayongayinye inesakhiwo sayo esiyingqayizivele kanye nezici zokusebenza, ezifanele ukusetshenziswa okuhlukile. Lapho ukhetha, kufanele kucatshangelwe kabanzi izici ezifana nezimo ezithile zokusebenza, izici eziphakathi kanye nezidingo zokusebenza kokuvala.
