Njengomshini wokuvula, wokuvala nokulawula wepayipi lokungena komoya kanye nokukhipha uthuli, i-valve yevemvane yokukhipha umoya ifanele ukushaywa komoya, ukususwa kothuli kanye nezinhlelo zokuvikela imvelo kwezensimbi, izimayini, usimende, imboni yamakhemikhali kanye nokuphehla ugesi.

I-ventilation butterfly valve icutshungulwa ibe yindandatho yokuvala enento efanayo nomzimba we-valve.Ukushisa kwayo okusebenzayo kuncike ekukhethweni kwezinto ezibonakalayo zomzimba we-valve, futhi ingcindezi yamagama ingu-≤ 0.6MPa.Ngokuvamile lisebenza ezimbonini, ezensimbi, ekuvikelweni kwemvelo kanye namanye amapayipi okungenisa umoya kanye nokulawula ukugeleza okuphakathi.

Izici zayo eziyinhloko:

1. Idizayini yenoveli nenengqondo, isakhiwo esiyingqayizivele, isisindo esilula nokuvulwa nokuvala ngokushesha.

2. I-torque encane yokusebenza, ukusebenza okulula, ukonga abasebenzi kanye nobuqili.

3. Izinto ezifanele zizosetshenziswa ukuze kuhlangatshezwane nezidingo zamazinga okushisa aphansi, aphakathi nendawo naphezulu kanye nemithombo yezindaba ebolayo.
