Cholinga chogwiritsa ntchito valavu ya cheke ndikupewa kutuluka kwa sing'anga, ndipo valavu yamawonekedwe nthawi zambiri imakhazikitsidwa pamalo opangira pampu. Kuphatikiza apo, valavu yoyang'ana iyeneranso kukhazikitsidwa pamalo opangira compressor. Mwachidule, pofuna kupewa kutuluka kwa sing'anga, valavu yoyang'ana iyenera kukhazikitsidwa pazida, chipangizo kapena paipi.
Nthawi zambiri, mavu ofunguza owongoka amagwiritsidwa ntchito pa mapaipi opingasa okhala ndi mainchesi a nomwenam. Vesi lowongoka lokweza limatha kukhazikitsidwa pamapaipi opingasa ndi ofukula. Valavu pansi nthawi zambiri imangoyikidwa pa mapaipi okhazikika a pampu, ndipo sing'anga imayenda kuchokera pansi mpaka pamwamba.
Swing Check Valve ikhoza kuchitika bwino kwambiri, PN ikhoza kufikira 42mpa, ndipo DN ikhoza kupangidwanso, yomwe ingafikire zoposa 2000mm. Malinga ndi zida zosiyanasiyana za chipolopolo, zimatha kugwiritsidwa ntchito panjira iliyonse yogwira ntchito komanso iliyonse yogwira ntchito. Wapakatikati ndi madzi, nthunzi, gasi, mipweya, mafuta, chakudya, mankhwala, ndi etc.
Malo okhazikitsa mawonekedwe a Swing Check sakhala ndi malire, nthawi zambiri amakhazikitsidwa pa mapaipi opingasa, koma amathanso kukhazikitsidwa pa mapaipi kapena mapaipi ophatikizika.
Nthawi yofunsidwa ya Butter Check ndi kukakamizidwa kochepa komanso mainchesi akulu, ndipo nthawi ya kukhazikitsa ndizochepa. Chifukwa kukakamizidwa kwa Gulugufe Kuyang'ana Kwambiri sikungakhale lalikulu kwambiri, koma mainloni mwadzina ndi omwe amatha kukhala akulu kwambiri, omwe amatha kufikira 2000mm, koma kupanikizika kwadzina. Vesi ya Gulugufe imatha kupangidwa kukhala mtundu wambiri, womwe nthawi zambiri amaikidwa pakati pa ma flanges awiri a paipi momwe amalumikizirana.
Malo okhazikitsa a Gulugufe Check Stuval sakhala ndi malire, imatha kukhazikitsidwa pa mapaipi opingasa, mapaipi kapena mapaipi ophatikizika.
Vesi ya Diaphragm ndiyoyenera ma piipelines omwe amakonda nyundo yamadzi. Diaphragm imatha kuthetsa nyundo yamadzi chifukwa cha kutuluka kwa sing'anga. Popeza kutentha kwa ntchito ndi kugwiritsira ntchito ma vaphragm cheke ndi malire a diaphragm, nthawi zambiri amagwiritsidwa ntchito popanikizika komanso kutentha - kutentha mapaipimu. Nthawi zambiri, kutentha kwa sing'anga kuli pakati -20 ~ 120 ℃, ndipo kuthamanga kwa ntchito ndi kochepa kwambiri.
Velave ya Diaphragm yagwiritsidwa ntchito kwambiri m'zaka zaposachedwa chifukwa cha ntchito yake yopanda madzi, kapangidwe kosavuta komanso mtengo wotsika.
Valavu ya mpira ali ndi magwiridwe antchito abwino, ntchito yodalirika komanso mphamvu yamadzi abwino pokana madzi chifukwa chisindikizo sichili ndi mphira; Ndipo chifukwa Chisindikizo chikhoza kukhala mpira umodzi kapena mipira ingapo, itha kukhala mainchesi yayikulu. Komabe, chisindikizo chake ndi chimbudzi chokutidwa ndi mphira, womwe suyenera kupanikizika kwambiri, koma kokha kwa mapaipi ndi otsika-ochepa.
Popeza zida za chipolopolo cha mpira cheke zitha kupangidwa ndi chitsulo chosapanga dzimbiri, ndipo gawo logwedezeka la chisindikizo lingaphimbe ndi pulasitiki ya PTF
Kutentha kwa mtundu uwu wa cheke ndi pakati -101 ~ 150 ~ Kupanikizika kwa nomweno ndi ≤4.0MPA, ndi mawonekedwe a nomwel ali pakati pa 200 ~ 1200mm.
