Vavu yachipata ingagwiritsidwe ntchito pamadzi ambiri.Ma valve a zipata ndi oyenera pansi pazigawo zogwirira ntchito izi: Madzi amchere, madzi otayira ndi madzi osalowerera ndale: kutentha pakati pa -20 ndi +80 ℃, kuthamanga kwa 5 m / s kuthamanga ndi kuthamanga kwa 16 bar.
Kagwiritsidwe: Vavu yachipata cha chisindikizo chofewa chimapeza chisindikizo chimafika ku chisindikizo, pogwiritsa ntchito mphamvu yomwe imachokera ku elastil sluice board, yatsani sing'anga, pomwe mphamvu yogwira ntchito ndi ≤ 1 MPa, kutentha kwa ntchito ndi ≤ 8 ° C.Amagwiritsidwa ntchito kwambiri mu architectonics, edibles, mankhwala, mphamvu zamagetsi, kugwiritsa ntchito ndi kukhetsa makampani amadzi, ndi zina zotero.
Ma valve okhala ndi ma ductile iron resilient amapangidwa kuti azipereka chithandizo chodalirika komanso chokhalitsa pamakina operekera madzi ndi kugawa.Mavavuwa amapangidwa molingana ndi British Standard BS5163 ndipo ndi oyenera kugwiritsidwa ntchito pamwamba pa nthaka komanso pansi pa nthaka.
Thupi la valavulo limapangidwa ndi chitsulo cha ductile, chomwe ndi chinthu champhamvu komanso chokhazikika chomwe chimatha kupirira kuthamanga kwambiri komanso kutentha.Valve imakhalanso ndi mpando wokhazikika, womwe umapereka chisindikizo cholimba komanso umalepheretsa kutuluka.Mpando wokhazikika umapangidwa ndi mphira wa EPDM kapena NBR, womwe umalimbana ndi dzimbiri komanso kuwononga mankhwala.
Chipata cha valve chimapangidwa kuti chiziyenda bwino komanso mosavuta, kupereka torque yochepa yogwiritsira ntchito komanso kuchepetsa chiopsezo cha kuwonongeka kwa valve.Chipatacho chimakutidwanso ndi epoxy kuti apereke chitetezo chowonjezera ku dzimbiri.
Valavu imagwiritsidwa ntchito pogwiritsa ntchito gudumu lamanja kapena gearbox, yomwe imalola kuwongolera kosavuta komanso kolondola kwa kayendedwe ka madzi.Valve ikhoza kukhazikitsidwa pamalo aliwonse, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazinthu zosiyanasiyana.
Ponseponse, ma ductile iron resilient resilient ma valves okhala pachipata ndi njira yodalirika komanso yotsika mtengo yoperekera madzi ndikugawa.Ndiosavuta kukhazikitsa, kugwiritsa ntchito, ndi kukonza, komanso kupereka ntchito yokhalitsa ndi nthawi yochepa.
