I-Valve yeSango leNsimbi Engagqwali

I-Valve yeSango leNsimbi Engagqwali

Ingxenye yokuvula nokuvala yevalvu yesango lensimbi engagqwali yisango, futhi indlela yokunyakaza kwesango iqonde ngqo ohlangothini loketshezi. Isango lensimbi engagqwali linezindawo ezimbili zokuvala. Izindawo ezimbili zokuvala zevalvu yesango yemodeli esetshenziswa kakhulu zakha i-wedge, futhi i-angle ye-wedge iyahlukahluka ngemingcele yevalvu. Isango levalvu yesango le-wedge lingenziwa libe yi-whole, ebizwa ngokuthi isango eliqinile; lingenziwa futhi libe isango elingadala ukuguqulwa okuncane ukuthuthukisa ukukhiqizwa kwalo futhi libuyisele ukuphambuka kwe-angle yokuvala ebusweni ngesikhathi sokucubungula. Ipuleti libizwa ngokuthi isango elinwebekayo. Izinto zevalvu yesango lensimbi engagqwali zihlukaniswe zibe yi-CF8, CF8M, CF3, CF3M, 904L, Insimbi Engagqwali Ephindwe Kabili (4A, 5A, 6A).

Izinhlobo Zamavalvu Esango Lensimbi Engagqwali

Ingahlukaniswa ngama-valve esango le-wedge kanye nama-valve esango ahambisanayo ngokuya ngokucushwa kwendawo yokuvala.

Amavalvu esango le-Wedgeingahlukaniswa kanje:

• Uhlobo lwesango elilodwa
• Uhlobo lwesango eliphindwe kabili
• Uhlobo lwesango elinwebekayo

I-Prallel Gate ValveIngahlukaniswa ibe

• Uhlobo lwesango elilodwa
• Uhlobo lwesango eliphindwe kabili

Ihlukaniswe ngokwesikhundla sentambo yesiqu sevalvu

Kungahlukaniswa ngezinhlobo ezimbili:

• I-valve yesango lesiqu esikhuphukayo
• Ivalvu yesango lesiqu esingavuki.

I-valve yesango lensimbi engagqwali ngokuvamile kufanele ifakwe ngokuvundlile epayipini.Uma ivalvu ivuliwe, lapho ukuphakama kwesango kulingana nobubanzi bevalvu obuphindwe ngo-1:1, indlela yoketshezi ivulwa ngokuphelele, kodwa lesi simo asikwazi ukubhekwa ngesikhathi sokusebenza.

Ekusetshenzisweni kwangempela, i-top of the valve stem isetshenziswa njengophawu, okungukuthi, indawo lapho ingenakuvulwa khona, njengendawo yayo evulekile ngokuphelele. Ukuze kucatshangelwe isenzakalo sokukhiya ngenxa yokushintsha kwezinga lokushisa, i-valve ivame ukuvulwa iye endaweni ye-apex bese ibuyiselwa emuva nge-1/2 kuya ku-1 turn njengendawo ye-valve evulekile ngokuphelele. Ngakho-ke, indawo evulekile ngokuphelele ye-valve inqunywa indawo yesango (okungukuthi i-stroke).

Kwamanye amavalvu esango, i-stem nut ibekwa esangweni, futhi ukujikeleza kwesondo lesandla kuqhuba ukujikeleza kwe-valve stem ukuze kuphakanyiswe isango. Lolu hlobo lwevalvu lubizwa ngokuthi i-rotary stem gate valve noma i-non-rising stem gate valve.
