Mupeza thupi la valavu pakati pa mapaipi olumikizirana pamene likugwirizira zigawo za valavu pamalo ake. Thupi la valavu ndi lachitsulo ndipo limapangidwa ndi chitsulo cha kaboni, chitsulo chosapanga dzimbiri, titaniyamu alloy, nickel alloy, kapena aluminiyamu bronze. Zonse kupatula carbon stell ndizoyenera malo owononga.
Thupi la valavu yowongolera gulugufe nthawi zambiri limakhala la mtundu wa lug, mtundu wa wafer, kapena lopindika kawiri.
- Lug
- Ma lugs otuluka omwe ali ndi mabowo a bolt kuti agwirizane ndi omwe ali mu flange ya chitoliro.
- Imalola ntchito yomaliza kapena kuchotsa mapaipi otsika.
- Maboluti okhala ndi ulusi kuzungulira dera lonselo amapangitsa kuti likhale njira yotetezeka.
- Amapereka chithandizo cha kumapeto kwa mzere.
- Ulusi wofooka umatanthauza kuti mphamvu yamagetsi imachepa
- Wafer
- Popanda zotchingira zotuluka ndipo m'malo mwake zimayikidwa pakati pa ma flange a chitoliro ndi mabotolo a flange ozungulira thupi. Ili ndi mabowo awiri kapena angapo ozungulira pakati kuti athandize pakuyika.
- Sichisuntha kulemera kwa makina opaira mapaipi mwachindunji kudzera m'thupi la valavu.
- Yopepuka komanso yotsika mtengo.
- Mapangidwe a ma wafer sasuntha kulemera kwa makina opaira mapaipi mwachindunji kudzera m'thupi la valavu.
- Sizingagwiritsidwe ntchito ngati chitoliro chomaliza.
- Yopindika kawiri
- Malizitsani ma flanges kumapeto onse awiri kuti mulumikizane ndi ma flanges a chitoliro (nkhope ya flange mbali zonse ziwiri za valavu).
- Chodziwika kwambiri ndi ma valve akuluakulu.
