Onani ma valveziyenera kuikidwa pa zipangizo, zipangizo ndi mapaipi pofuna kupewa sing'anga countercurrent.
Kuthamanga kocheperako kotsegulira kwa valve cheke ndi 0.002-0.004mpa.
Onani ma valventhawi zambiri ndi oyenera kuyeretsa media, osati pazofalitsa zomwe zimakhala ndi tinthu tolimba komanso kukhuthala kwakukulu.
Thevalavu ya phaziNthawi zambiri imayikidwa papaipi yoyima ya polowera, ndipo sing'angayo imayenda kuchokera pansi kupita pamwamba.
Mtundu wokweza umakhala ndi ntchito yabwino yosindikiza kuposa mtundu wa swing, ndipo imakhala ndi kukana kwamadzimadzi kokulirapo.Mtundu wopingasa ukhazikike mupaipi yopingasa, ndipo mtundu woyimirira ukhazikitsidwe mupaipi yoyima.
Kuyika malo a swing check valve sikokwanira.Itha kukhazikitsidwa mumipaipi yopingasa, yoyima kapena yokhotakhota.Ngati aikidwa mu mapaipi ofukula, njira yoyendetsera sing'anga iyenera kukhala kuchokera pansi kupita pamwamba.
Swing ma valvesayenera kupangidwa kukhala mavavu ang'onoang'ono a caliber, ndipo amatha kukhala othamanga kwambiri.Kuthamanga mwadzina kumatha kufika 42 MPa, ndipo m'mimba mwake mwadzina kungakhalenso kwakukulu, mpaka 2000 mm.Itha kugwiritsidwa ntchito pa sing'anga iliyonse yogwirira ntchito komanso kutentha kulikonse komwe kumagwirira ntchito molingana ndi chipolopolo ndi chisindikizo.Pakatikati ndi madzi, nthunzi, gasi, sing'anga zowononga, mafuta, mankhwala, ndi zina zotero. Kutentha kogwira ntchito kwa sing'anga ndi - 196 - 800 C.
Swing check valve ndi yoyenera kutsika kwapansi ndi caliber yaikulu, ndipo kuika kwake kuli kochepa.
Kuyika kwa valve yoyang'ana kavalo sikuli malire.Ikhoza kuikidwa mu payipi yopingasa kapena mupaipi yoyima kapena yokhotakhota.
Ma valve oyang'ana mpirandi oyenera mapaipi apakati ndi otsika komanso amatha kupangidwa kukhala wamkulu.
Chigoba cha valve yowunikira mpira chikhoza kupangidwa ndi chitsulo chosapanga dzimbiri, ndipo gawo lopanda kanthu la chisindikizo likhoza kukulungidwa mu mapulasitiki a PTFE engineering.Chifukwa chake, itha kugwiritsidwanso ntchito m'mapaipi a media owononga.Kutentha kogwira ntchito kuli pakati pa - 101 - 150 C, kuthamanga mwadzina ndi kochepera 4.0 MPa, ndipo kuphatikizika mwadzina kuli pakati pa DN200 - DN1200.
Onani ma valveziyenera kukulitsidwa molingana.Opereka ma valve ayenera kupereka deta pa makulidwe osankhidwa kuti apeze kukula kwa ma valve pamene atsegulidwa kwathunthu pa mlingo woperekedwa.
Kwa kuthamanga kwapamwamba ndi kwapakatifufuzani ma valvepansi pa DN50mm,mavavu okwera okwerandi kudzerakukweza ma valveziyenera kusankhidwa.
Kwa kuthamanga kwapansifufuzani ma valvepansi pa DN50mm,valavu yoyang'ana pansindimavavu okwera okweraziyenera kusankhidwa.
Kwa kuthamanga kwapamwamba ndi kwapakatifufuzani ma valvendi DN wamkulu kuposa 50 mm ndi zosakwana 600 mm,kusintha ma valveziyenera kusankhidwa.
Kwa kuthamanga kwapakati ndi kochepafufuzani ma valvendi DN wamkulu kuposa 200 mm ndi zosakwana 1200 mm, osavalama valve a mpiraziyenera kusankhidwa.
Kwa kuthamanga kwapansifufuzani ma valvendi DN wamkulu kuposa 50 mm ndi zosakwana 2000 mm,valavu yoyang'ana pansiziyenera kusankhidwa.
Pamapaipi omwe amafunikira nyundo yochepa kapena yopanda madzi potseka, valavu yotsekera yotseka pang'onopang'ono iyenera kusankhidwa.
