Ama-valve esango angahlukaniswa abe:

1, i-valve yesango lenduku evulekile:

Vula i-stem gate valve: I-stem nut ikukhava noma kubakaki.Lapho uvula futhi uvala ipuleti lesango, isiqu singaphakanyiswa noma sehliswe ngokuzungezisa i-stem nut.Lesi sakhiwo sivuma ukuthambisa i-stem, izinga lokuvula nokuvala liyabonakala, ngakho-ke lisetshenziswa kabanzi.

Imvamisa kunemicu ye-trapezoidal entweni yokuphakamisa, ngokusebenzisa nati phezulu kwe-valve kanye ne-groove eqondisayo emzimbeni, ukunyakaza okujikelezayo kube ukunyakaza okuqondile, okungukuthi, i-torque yokusebenza ingena ekugxilweni kokusebenza.

Ingxenye yokuvula nokuvala ye-valve yesango yipuleti lesango, isiqondiso sokunyakaza kwepuleti lesango sibhekene nesiqondiso se-fluid, i-valve yesango ingavulwa ngokugcwele futhi ivalwe, ayikwazi ukulungiswa futhi ifakwe.

2, ivalve yesango lenduku emnyama:

I-valve yesango lenduku emnyama ibizwa nangokuthi i-valve yesango lenduku ejikelezayo (eyaziwa nangokuthi ivalve yesango lenduku emnyama).I-stem nut isemzimbeni we-valve ngokuthintana ngqo nendawo.Ukuze uvule futhi uvale isango, zungeza isiqu.

Ingxenye yokuvula neyokuvala ye-valve yesango elimnyama yi-plate yesango, isiqondiso sokunyakaza kwepuleti lesango sibhekene nesiqondiso soketshezi, i-valve yesango ingavulwa ngokugcwele futhi ivalwe, ayikwazi ukulungiswa futhi ifakwe.

I-stem nut itholakala epuleti lesango, futhi isondo lesandla liyaphenduka ukuze lishayele isiqu ukuze lijikeleze futhi liphakamise ipuleti lesango.Ngokuvamile kunentambo ye-trapezoidal phansi kwesiqu.Ngentambo engezansi kwe-valve kanye ne-groove ye-guide ku-disc ye-valve, ukunyakaza okujikelezayo kuguqulwa kube ukunyakaza okuqondile, okungukuthi, i-torque yokusebenza iguqulwa ibe yi-thrust yokusebenza.

Umehluko omkhulu phakathi kwama-valve esango lenduku evulekile nama-valve esango lenduku emnyama imi kanje:

1, isikulufu esiphakamisayo se-valve yesango lenduku emnyama siyazungeza kuphela futhi akukho ukunyakaza okungaphezulu nangaphansi, okuveziwe kuyinduku kuphela, inathi lalo ligxiliswe epuleti lesango, ngokuzungezisa isikulufu ukuze kuphakanyiswe ipuleti lesango, lapho alukho uhlaka olubonakalayo;Isikulufu esiphakamisayo se-valve yesango lenduku evulekile sisobala, inathi liseduze nesondo lesandla futhi ligxilile (akukho ukuzungezisa futhi akukho mnyakazo we-axial), isango liphakanyiswa ngokuzungezisa isikulufu, isikulufu nesango kunokuzungezisa okuhlobene kuphela. ukunyakaza kodwa akukho okuhlobene kwe-axial displacement, futhi ukubukeka kubakaki obumise komnyango.

2, i-valve yesango lenduku emnyama ayikwazi ukubona isikulufu sokuhola, futhi induku evulekile ingabona isikulufu sokuhola.

3. Isondo lokuqondisa kanye nesiqu se-valve kuxhunywe ndawonye lapho i-valve yesango elimnyama ivuliwe futhi ivaliwe.Iqhutshwa isiqu se-valve esiphenduka endaweni engaguquki ukuze iphakamise i-disc ye-valve phezulu naphansi ukuze iqedele ukuvula nokuvala.Vula amavalvu e-STEM GATE phakamisa noma wehlise i-disc NGOKUHLULISELA isiqu esondweni lesiteringi.Iphuzu elilula ukuthi i-valve yesango ye-stem evulekile yi-disc exhunywe esiqwini esihamba phezulu naphansi ndawonye, ​​isondo lokuqondisa lihlala liyiphoyinti eliqondile.
