Mfundo yomanga ma valve a butterfly ndi zochitika zomwe zimagwira ntchito

Awiri kusanthula kwakukulu kwavalavu ya butterflymalo oyika: malo oyika, kutalika, ndi mayendedwe olowera ndi potuluka ayenera kukwaniritsa zofunikira pakupanga.Zindikirani kuti mayendedwe apakati ayenera kukhala ogwirizana ndi momwe muvi wasonyezera pa thupi la valve, ndipo kugwirizana kuyenera kukhala kolimba komanso kolimba.Vavu yagulugufe iyenera kuyang'aniridwa bwino musanayike, ndipo dzina la valve liyenera kutsatira muyezo wapadziko lonse wa "General Valve Mark" GB12220.Kwa ma valve omwe ali ndi mphamvu yogwira ntchito yoposa 1.0MPa ndi ntchito yodulidwa pa chitoliro chachikulu, kuyesa mphamvu ndi zolimba ziyenera kuchitidwa musanayike.Ikhoza kugwiritsidwa ntchito pambuyo pa oyenerera.Pakuyezetsa mphamvu, kupanikizika kwa mayeso ndi 1.5 kuwirikiza mwadzina, ndipo nthawiyo siichepera mphindi 5.Nyumba ya valve ndi kulongedza ziyenera kukhala zoyenerera popanda kutayikira.Vavu ya butterfly imatha kugawidwa m'mitundu yofananira, mbale yoyima, mtundu wamba, ndi mtundu wa lever malinga ndi kapangidwe kake.Malingana ndi mawonekedwe osindikizira, akhoza kugawidwa mu mtundu wofewa wosindikizira ndi mtundu wosindikiza mwamphamvu.Chisindikizo chofewa nthawi zambiri chimasindikizidwa ndi mphete ya rabara, ndipo mtundu wa chisindikizo cholimba nthawi zambiri umasindikizidwa ndi mphete yachitsulo.
Kapangidwe ka valavu ya butterfly:
Vavu yagulugufe nthawi zambiri imakhala ndi cholumikizira chamagetsi chamagetsi (0 ~ 90 ° kasinthasintha pang'ono) ndi valavu yagulugufe yonse kudzera mu kulumikizana kwamakina, pambuyo poika ndi kukonza zolakwika.Malinga ndi machitidwe, pali: kusintha mtundu ndi kusintha mtundu.Mtundu wosinthira ndikulumikiza mwachindunji magetsi (AC220V kapena magetsi ena) kuti mumalize kusinthako posinthira mayendedwe akutsogolo ndi kumbuyo.Mtundu wosinthika umayendetsedwa ndi magetsi a AC220V, ndipo umalandira chizindikiro cha 4 ~ 20mA (0 ~ 5 ndi zizindikiro zina zofooka) zamakina owongolera makina kuti amalize kusintha.

Kugwiritsa ntchito ma valve a butterfly:
Ma valve a butterfly ndi oyenera kuwongolera kayendedwe kake.Popeza kuthamanga kwa valavu ya gulugufe mu payipi kumakhala kwakukulu, kulimba kwa mbale ya gulugufe kuti zisapirire kupanikizika kwa sing'anga ya mapaipi kuyenera kuganiziridwanso ikatsekedwa.Kuphatikiza apo, kuchepa kwa kutentha kwa zinthu zapampando wa elastomeric pamatenthedwe okwera kuyeneranso kuganiziridwa.Kutalika kwa dongosolo ndi kutalika kwa valavu ya gulugufe ndizochepa, kutsegula ndi kutseka kufulumira, ndipo kumakhala ndi makhalidwe abwino olamulira madzimadzi.Kapangidwe ka valavu ya gulugufe ndi yabwino kwambiri popanga ma valve akulu akulu.Pamene valavu ya butterfly ikufunika kuti igwiritsidwe ntchito poyendetsa kayendetsedwe kake, chinthu chofunika kwambiri ndikusankha molondola kukula ndi mtundu wa valavu ya butterfly kuti igwire bwino ntchito.
Vavu ya butterfly ndi yoyenera madzi abwino, zimbudzi, madzi a m'nyanja, madzi amchere, nthunzi, gasi, chakudya, mankhwala, mafuta ndi ma acid osiyanasiyana omwe amafunikira kusindikiza, kutayikira kwa zero pamayeso a gasi, kutalika kwa moyo, komanso kutentha kwapakati pa -10 madigiri. ndi madigiri 150.Alkali ndi mapaipi ena.
