Vavu yooneka ngati V yoyambira

Valavu ya mpira wamtundu wa V ndi valavu ya mpira yotsekedwa mwamphamvu, yosindikizidwa ndi tetrafluoro.

Imatengera mawonekedwe a mpando wa valve wonyamulidwa ndi kasupe wa masamba, mpando wa valve ndi thupi la mpira sizidzayambitsa mavuto monga kupanikizana kapena kupatukana, ndipo kusindikiza ndi kodalirika ndipo moyo wautumiki ndi wautali.

Spool ya valve yopangidwa ndi V yopangidwa ndi V imapangidwa ngati kusiyana kwa V yokhala ndi chosinthira chapadera, chokhala ndi mphamvu yothamanga kwambiri, kuchepa kwapang'onopang'ono, ndi zizindikiro zolondola zotseka ndi ntchito zolamulira.

Mayendedwe ake ndi pafupifupi ofanana maperesenti.

Magawo otsegulira ndi otseka amatenga mawonekedwe a mpira wooneka ngati V, omwe amathetsa vuto la kuyika kosavuta kwa sing'anga mu valavu.

Vavu ya mpira wa V-mtundu ndi yoyenera mapaipi osiyanasiyana okhala ndi Class150～600, PN1.6～10.0MPa, ndi kutentha kwa ntchito ≤200℃. Amagwiritsidwa ntchito kusintha kuthamanga ndi kutuluka kwa sing'anga mu payipi.

Zida zosiyanasiyana zimasankhidwa, zomwe zingagwiritsidwe ntchito pazinthu zosiyanasiyana monga madzi, nthunzi, mafuta, nitric acid, acetic acid, oxidizing sing'anga, urea, etc.

Chifukwa palibe kusiyana pakati pa pachimake cha valve ndi mpando wa valve, imakhala ndi mphamvu yometa ubweya wambiri komanso yodziyeretsa yokha, makamaka yoyenera kuwongolera kuyimitsidwa ndi tinthu tating'ono tomwe timakhala ndi tinthu tating'onoting'ono ta fibrous kapena ting'onoting'ono.

Chifukwa chake, mankhwalawa angagwiritsidwe ntchito kwambiri pamakina owongolera amafuta, mankhwala, kupanga mapepala, mphamvu yamagetsi, zitsulo, mankhwala, chitetezo cha chilengedwe ndi magawo ena amakampani.
