Palibe kukakamizidwa koipa. Fluorine alimbane mavavu pulasitiki ayenera kugwiritsidwa ntchito mmene angathere mu payipi pali kuthamanga zoipa, ngati pali kuthamanga zoipa, zosavuta kutsogolera fluorine alimbane pulasitiki wosanjikiza wa mkati khoma la valavu anayamwa (kudzitukumula), kuwola. , zomwe zimabweretsa kutseguka kwa valve, kutseka kulephera. 3, kuthamanga ntchito, kuthamanga kusiyana sayenera upambana osiyanasiyana kololeka. Makamaka, mavuvuwo amasindikizidwa ndi ma valve owongolera pulasitiki a fluorine ndi ma valve odulidwa. Chifukwa mavuvu achitsulo amapangidwa ndi zinthu za PTFE, kupanikizika kogwira ntchito komanso kutsika pang'ono ndikosavuta kupangitsa kuti zitsulo zing'ambika. Mabelu osindikizidwa ndi valavu yoyendetsera pulasitiki ya fluorine, kupanikizika kogwira ntchito, kutsika kochepa, kungasinthidwe kukhala zosindikizira zinayi za fluorine. 4, valavu ya pulasitiki ya fluorine yomwe imagwiritsidwa ntchito ndi sing'anga si yoyenera kwa tinthu tating'onoting'ono tolimba, makhiristo, zotsalira, ndi zina zotero, pofuna kuteteza valavu poyera, kuletsa ntchito ya mtima wa valve, kuthamanga kwa chipata cha valve chotchinga pulasitiki wosanjikiza. kapena fluorine. Sing'anga imakhala ndi tinthu tating'ono tolimba, makhiristo, zonyansa, zikagwiritsidwa ntchito, valavu ya valve, valve yothamanga kwambiri imatha kusinthidwa kukhala Hastelloy. 5, yokhala ndi valavu yoyang'anira pulasitiki ya fluorine iyenera kukhala yogwirizana ndi mayendedwe oyenera a pulatifomu (mtengo wa Cv) kugwiritsa ntchito koyenera kwa valavu. Muzosankha, ziyenera kukhazikitsidwa pa siteji yoyenera kuyenda (mtengo wa Cv) ndi magawo ena ogwira ntchito kuti awerengere valavu ayenera kusankha m'mimba mwake ndi digiri yotsegulira valavu, monga kusankha kwa valve m'mimba mwake ndi yaikulu kwambiri, imayenera kupanga valavu yaitali. -nthawi yogwira ntchito poyang'ana digiri yaing'ono yotsegulira, kuphatikizapo kupanikizika kwapakatikati, kuti zikhale zosavuta kupanga pakati pa valve, ndodo imakhudzidwa ndi mphamvu yapakati ndiyeno valve imayambitsa kugwedezeka, tsinde la valve likukhudzidwa ndi sing'anga yonse. chaka chonse, ndipo ngakhale mpando wa valve udzasweka. Makasitomala pakugwiritsa ntchito mitundu yonse ya mavavu apulasitiki okhala ndi fluorine, ayenera kuyesa kumvetsetsa, kumvetsetsa kugwiritsa ntchito miyezo yaukadaulo, yosavuta kusankha, kugwiritsa ntchito bwino, kusintha moyo wautumiki wa valavu.
