M'dziko la kayendetsedwe ka madzimadzi, kusankha kwa valve ndi fyuluta ndizofunika kwambiri kuti zitsimikizidwe kuti machitidwe akuyenda bwino komanso odalirika. Zina mwazosankha zosiyanasiyana zomwe zilipo, ma valve awiri amtundu wa wafer ndi swing check valve flanged amawonekera chifukwa cha mawonekedwe awo apadera. Mukagwiritsidwa ntchito limodzi ndi Y-strainer, zigawozi zimapanga dongosolo lamphamvu kuti lizitha kuyendetsa ndikuletsa kubwerera.
**valavu yoyang'ana mbale ziwiri**
Ma valve oyendera mbale ziwiriadapangidwa kuti azigwiritsidwa ntchito pomwe malo ali ochepa. Mapangidwe ake ophatikizika amalola kuyika kosavuta pakati pa ma flanges, ndikupangitsa kuti ikhale yabwino kugwiritsidwa ntchito m'malo olimba. Valavu imagwira ntchito ndi mbale ziwiri zomwe zimatsegula ndi kutseka molingana ndi kayendetsedwe ka kayendedwe kake, kuteteza bwino kubwerera. Kumanga kwake kopepuka komanso kutsika kwapang'onopang'ono kumapangitsa kukhala chisankho chodziwika bwino m'mafakitale osiyanasiyana, kuphatikiza chithandizo chamadzi ndi machitidwe a HVAC.
**Flange mtundu swing check valve**
Poyerekeza,mavavu oyendera ma flangedndizoyeneranso mapaipi akuluakulu. Vavu ili ndi diski yokhotakhota yomwe imatseguka kuti ipite patsogolo ndikutseka kuti ibwerere kumbuyo. Mapangidwe ake olimba amatha kuthana ndi zovuta zambiri komanso ma voliyumu akulu, ndikupangitsa kuti ikhale yabwino kwa mafakitale. Malumikizidwe a flanged amaonetsetsa kuti ali otetezeka, kuchepetsa chiopsezo cha kutayikira komanso kukulitsa kukhulupirika kwa dongosolo.
**Y fyuluta**
Y-strainerszimathandizira ma cheki mavavuwa ndipo ndi gawo lofunikira pakuteteza mapaipi ku zinyalala ndi zowononga. TheY-straineramasefa kunja zapathengo particles, kuonetsetsa madzimadzi oyenda mu dongosolo amakhala woyera. Izi ndizofunikira makamaka pamakina omwe kukhulupirika kwamadzimadzi kumakhala kofunikira, monga kukonza mankhwala kapena njira zoperekera madzi.
**Pomaliza**
Kuphatikizira ma valve owunika a TWS ndi ma Y-strainer mumayendedwe anu owongolera madzimadzi kumawongolera magwiridwe antchito komanso kudalirika. Ma valve awiri oyendera mbale ndi ma valve oyendera cheke ophatikizidwaY-strainersperekani yankho lathunthu la kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake ndi kusunga umphumphu wa dongosolo. Posankha zigawo zoyenera, mafakitale amatha kuonetsetsa kuti ntchito yabwino komanso moyo wautali wa machitidwe awo oyendetsera madzi.
