I-globe valve ne-valve yebhola

Njengamanje, kunezinhlobo ezahlukene zama-valve ebhola kanye nama-valve embulunga emakethe yezinhlelo zokusebenza ezihlukene zendawo ezungezile, ngakho-ke sihlola kanjani futhi sifakazele ukukhethwa kwe-valve yebhola efanele ukuze sizuze umphumela wokufaka isicelo ongcono kakhulu?Esihlokweni esilandelayo, uRonnie Shidun uxoxa ngezinzuzo zama-valve ebhola nama-globe valves nawo wonke umuntu.

1. Umehluko omkhulu phakathi kwama-valve amabili
Njengoba sonke sazi, umehluko omkhulu phakathi kwe-valve yembulunga kanye ne-valve yebhola yindlela yokuvala.Ama-valve eglobhu ngokuvamile asetshenziselwa ukuphonseka, kodwa ama-valve ebhola asebenzisa ibhola ukuvala ukugeleza.I-valve yokumisa ilungele ukulungisa ukugeleza, kuyilapho i-valve yebhola isebenza kahle kakhulu futhi ingakwazi ukulawula ukugeleza ngaphandle kokwehla kwengcindezi.
I-valve yebhola inesiqu kanye nebhola elizungezayo elivundlile, futhi livame ukubizwa ngokuthi ivalvu “ezungezayo”.Kodwa-ke, i-valve yembulunga inesiqu se-valve kanye ne-valve core, kanti isiqu se-valve ne-valve core ithatha i-stroke eqondile, kanti i-valve yokumisa lapho itholakala khona ibizwa nangokuthi "i-stroke".

2. Izici eziyisisekelo zama-valve amabili
I-valve yebhola:
I-1) Ukuvinjelwa koketshezi kwe-valve yebhola kuncane, futhi umsindo wokusebenza uphansi;
2) Lolu hlobo lwe-valve lunesakhiwo esilula, ukufakwa okungenamkhawulo, usayizi omncane kakhulu, isisindo esilula, kanye nezidingo eziphansi zesondlo.
3) I-medium ye-valve yebhola iyahlukana futhi igeleze ngaphandle kokudlidliza;
4) Ukunemba kokucubungula kwe-valve yebhola kuphezulu, futhi izindleko ziphezulu;
5), awukwazi ukuphefumula.

I-valve yokuvala:
1).Lolu hlobo lwe-valve lunesakhiwo esilula kanye nezidingo eziphansi zokucubungula nokugcinwa.
2) I-valve yokuvala ingavulwa futhi ivalwe ngesikhathi esifushane ngaphansi kokusebenza kwesikhashana;
3) Ukusebenza kokubeka uphawu kuhle, ukungqubuzana endaweni yokuvala kuncane, futhi kungasetshenziswa isikhathi eside.
I-4) Ukuvinjelwa kwamanzi kwalolu hlobo lwe-valve kukhulu kakhulu, futhi amandla amakhulu azokhiqizwa ngesikhathi sokuvula nokuvala inqubo.
5) I-valve yokumisa ayifanele ukulawula uketshezi ngezinhlayiya ze-viscous.

3. Ungayenza kanjani ukukhetha okungcono phakathi kwe-valve yebhola ne-globe valve?
I-valve yebhola ihlala isikhathi eside futhi isebenza kahle ngemva kwemijikelezo eminingi;inokwethenjelwa futhi ingavalwa ngokuphepha ngisho noma ihlukunyezwa isikhathi eside.Uma kuqhathaniswa namavalvu esango namavalvu eglobhu, lezi zici zisiza ama-valve ebhola ukuthi abe yisinqumo esibalulekile ezinhlelweni zokuvala.Ngakolunye uhlangothi, ama-valve ebhola awakwazi ukulawula kahle izinhlelo zokusebenza ze-throttling ezinikezwa ama-globe valves.
