Mafotokozedwe Akatundu
Valavu yachitsulo chopangidwa ndi chitsulo chopangidwa ndi trunnion nthawi zambiri imagwiritsidwa ntchito m'mapaipi opangidwa ndi mphamvu yapakati mpaka yapamwamba, makamaka komwe kumafunika kukula kwakukulu kwa mavavu kapena kugwira ntchito kokhazikika. Thupi la valavu ndi zida zazikulu zosungira mphamvu zimapangidwa kuchokera ku chitsulo chopangidwa ndi chitsulo chopangidwa, zomwe zimapereka kapangidwe ka zinthu kogwirizana komanso mphamvu yodalirika yamakina kuti igwire ntchito kwa nthawi yayitali.
Mpirawo umathandizidwa ndi ma trunnion apamwamba ndi otsika. Kupanikizika kwa payipi kumasamutsidwira ku thupi la valavu m'malo mwa tsinde, zomwe zimathandiza kuchepetsa mphamvu yogwirira ntchito ndikuchepetsa kuyenda kwa mpira pansi pa kusintha kwa kupanikizika. Kapangidwe kameneka nthawi zambiri kamasankhidwa kuti kagwiritsidwe ntchito ka magulu amphamvu kwambiri kapena kawirikawiri.
Kapangidwe ka mipando ndi zipangizo zotsekera zitha kusankhidwa kutengera momwe ntchito ikuyendera. Mapangidwe onse okhala ndi mipando yofewa komanso yokhala ndi mipando yachitsulo amapezeka kutengera kutentha, malo olumikizirana, ndi momwe mipandoyo imagwirira ntchito.

Zolemba za Kapangidwe
Valavu imagwira ntchito ndi kutembenuka kwa madigiri 90.
Kapangidwe kamene kamayikidwa pa trunnion kamasunga mpirawo pamalo okhazikika, zomwe zimapangitsa kuti ukhale wolamulira bwino komanso wokhazikika poyerekeza ndi mapangidwe a mipira yoyandama, makamaka yayikulu.
Mipando yolumikizira mipando ingaphatikizepo mapangidwe okhala ndi masika kapena othandizira kupanikizika kuti isunge magwiridwe antchito otseka pansi pa mikhalidwe yosiyanasiyana ya kupsinjika.

Mapulogalamu Odziwika
Yoyenera mapaipi okhala ndi mphamvu yapakati mpaka yapamwamba, makina akuluakulu, ndi ntchito zomwe zimafunika kugwira ntchito mokhazikika komanso kutseka kodalirika. Imagwiritsidwa ntchito kwambiri mu mafuta ndi gasi, kukonza mankhwala, kupanga magetsi, ndi mapaipi wamba a mafakitale.

Ma valve a mpira opangidwa ndi chitsulo chopangidwa ndi trunnion nthawi zambiri amasankhidwa pamene mapangidwe a mpira woyandama sali oyenera chifukwa cha kuchuluka kwa kupanikizika, kukula kwa valavu, kapena momwe ntchito ikuyendera. Kapangidwe komaliza kayenera kutsimikiziridwa kutengera zofunikira zenizeni zautumiki ndi zomwe polojekitiyi ikufuna.
