Mudzapeza thupi la valavu pakati pa mapiko a chitoliro pamene limagwira zigawo za valve m'malo mwake. Ma valve a thupi ndi chitsulo ndipo amapangidwa kuchokera ku chitsulo cha carbon, chitsulo chosapanga dzimbiri, titaniyamu alloy, nickel alloy, kapena aluminium bronze. Zonse kupatulapo mpweya wa carbon ndizoyenera malo owononga.
Thupi la valavu yowongolera gulugufe nthawi zambiri limakhala mtundu wa lug, mtundu wawafer, kapena wopindika pawiri.
- Lug
- Mapaipi otuluka omwe ali ndi mabowo a bawuti kuti agwirizane ndi omwe ali mu chitoliro.
- Amalola ntchito yomaliza kapena kuchotsa mapaipi otsika.
- Maboti okhala ndi ulusi kuzungulira dera lonselo amapangitsa kukhala njira yotetezeka.
- Amapereka ntchito zomaliza.
- Ulusi wochepa mphamvu umatanthauza kutsika kwa torque
- Wafer
- Popanda zotuluka lugs ndi m'malo sandwich pakati pa chitoliro flanges ndi flange mabawuti mozungulira thupi. Ili ndi mabowo awiri kapena kuposerapo kuti athandizire kukhazikitsa.
- Simasamutsa kulemera kwa mapaipi kudzera mu thupi la valve mwachindunji.
- Zopepuka komanso zotsika mtengo.
- Mapangidwe a Wafer samasamutsa kulemera kwa mapaipi molunjika kudzera mu thupi la valve.
- Sangagwiritsidwe ntchito ngati mapeto a chitoliro.
- Pawiri flanged
- Malizitsani ma flanges kumbali zonse ziwiri kuti mugwirizane ndi ma flanges a chitoliro (nkhope ya flange kumbali zonse za valve).
- Zotchuka pamavavu akulu akulu.
