Kusiyana pakati pa hard seal butterfly valve ndi soft seal butterfly valve

Zisindikizo zolimba zimapangidwa ndi zitsulo, monga ma gaskets achitsulo, mphete zachitsulo, ndi zina zotero, ndipo kusindikiza kumatheka chifukwa cha mikangano pakati pa zitsulo.Chifukwa chake, ntchito yosindikiza ndiyosauka, koma valavu yathu ya ZFA idapangidwavalavu yagulugufe yamitundu yambiri yosanjikiza katatuakhoza kukwaniritsa zero leak.Zisindikizo zofewa zimapangidwa ndi zipangizo zotanuka, monga mphira, PTFE, ndi zina zotero. Kwa zipangizo zina zomwe zimakhala ndi kutentha kwakukulu komanso kuthamanga kwambiri, zomwe sizingakwaniritse zofunikira za ndondomekoyi, ma valve a butterfly otsekedwa mwamphamvu amatha kuthetsa vutoli.
Kusiyana pakati pa mavavu agulugufe osindikizidwa mwamphamvu ndi ma valve agulugufe osindikizidwa mofewa:
1. Kusiyana kwamapangidwe: Mavavu agulugufe ofewa amakhala agulugufe apakati komansoawiri eccentric agulugufe mavavu, pamene hard seal agulugufe mavavu ambiri eccentric agulugufe mavavu ndiatatu eccentric agulugufe mavavu.
2. Kutentha kwa kutentha: Chisindikizo chofewa chimagwiritsidwa ntchito kumalo otentha, Rubber -20 ℃ ~ + 120 ℃, PTFE -25 ℃ ~ + 150 ℃.Chisindikizo cholimba chingagwiritsidwe ntchito kutentha kochepa, kutentha kwabwino, kutentha kwakukulu ndi malo ena, LCB kwa -29 ° C -+180 ° C, WCB ≤425 ° C, Stainless Steel≤600 ° C.
3. Kupanikizika: Kusindikiza kofewa kutsika-kuthamanga kwachibadwa PN6-PN25, chisindikizo cholimba chingagwiritsidwenso ntchito pakatikati ndi kupanikizika kwakukulu monga PN40 ndi pamwamba.
4. Kusindikiza: Vavu yagulugufe yofewa komanso valavu yagulugufe yolimba yolimba katatu imakhala ndi ntchito yabwino yosindikiza.Katatueccentric butterfly valveimatha kusunga chisindikizo chabwino cha zero pakuthamanga kwambiri komanso kutentha kwambiri.Komabe, ndizovuta kuti mavavu agulugufe wamba omata mwamphamvu kuti asatayike.
5. Moyo wautumiki: Ma valve a butterfly osindikizidwa ofewa amatha kukalamba ndi kuvala, ndipo moyo wawo wautumiki uyenera kukhala waufupi.Mavavu agulugufe osindikizidwa mwamphamvu amakhala ndi moyo wautali wautumiki.
Poganizira zomwe zili pamwambazi, valavu ya butterfly yapakati ndi yoyenera kugwiritsidwa ntchito m'madzi abwino, zimbudzi, madzi a m'nyanja, madzi amchere, nthunzi, gasi, chakudya, mankhwala, mafuta a petroleum, kutsegula ndi kutseka kwa mpweya wabwino komanso kuchotsa fumbi, ndi zidulo zosiyanasiyana kutentha ambiri, kupanikizika ndi nkhani zosawononga TV.Alkali ndi mapaipi ena amafunikira kusindikizidwa kwathunthu, kuyesa kutayikira kwa zero, ndi kutentha kwa -10 ~ 150 ℃.Valavu yagulugufe yotsekedwa mwamphamvu ndi yoyenera pazochitika zomwe zimakhala ndi kutentha kwakukulu, kuthamanga kwambiri komanso zowononga zowonongeka, monga kuwongolera ndi kugwedeza zipangizo zamapaipi amafuta, gasi, asidi ndi alkali monga kutenthetsa m'tawuni, gasi, madzi, mafuta, petrochemical, makampani opanga mankhwala, zitsulo, ndi mphamvu zamagetsi.ndi minda ina.Ndiwolowa m'malo mwa ma valve a zipata ndi ma valve a globe.
