Njira zingapo zothanirana ndi vuto losasindikiza bwino la mavavu

Ntchito yosindikiza ya valve ndi imodzi mwazinthu zazikulu zowunikira mtundu wa valve. Kusindikiza kwa valavu kumaphatikizapo mbali ziwiri, zomwe ndi, kutuluka mkati ndi kutuluka kunja. Kutuluka kwamkati kumatanthawuza digiri yosindikiza pakati pa mpando wa valve ndi gawo lotsekera, ndipo kutuluka kwakunja kumatanthauza kutayikira kwa gawo lodzaza la tsinde la valve, kutayikira kwa gasket yapakati ya flange ndi kutayikira kwa thupi la valve chifukwa cha vutolo. wa gawo loponya. Ngati ntchito yosindikiza ma valve ndi yolakwika, musadandaule kwambiri, mongamphira wokhala ndi butterfly valve, valve yokhazikika pachipata & valavu yoyendera mbale ziwiri, mukhoza kuyesa njira zotsatirazi poyamba.

1. Njira yopera

Kupera bwino, kuchotsa zotsalira, kuchepetsa kapena kuthetsa chilolezo chosindikizira, kukonza kusalala kwa malo osindikizira, kupititsa patsogolo ntchito yosindikiza.

2. Use the unbalanced mphamvu kuonjezera kusindikiza kukakamiza njira yeniyeni

Makina osindikizira osindikizira opangidwa ndi thupi la valve ndi otsimikizika, pamene mphamvu yosagwirizana imapanga njira yotsegulira pamwamba pa valve core, mphamvu yosindikizira ya thupi la valve imachepetsedwa ndi mphamvu ziwiri, m'malo mwake, njira yotseka yotseka, mphamvu yosindikiza ya pachimake cha valve ndi kuchuluka kwa mphamvu ziwirizo, zomwe zimawonjezera kwambiri kusindikiza kwapadera, kusindikiza kungathe kupitirira nthawi 5 ~ 10 kuposa yoyamba. General dg 20 valavu imodzi yosindikizira ndizochitika zakale, nthawi zambiri zimatuluka mtundu wotseguka, ngati kusindikiza sikukhutiritsa, kusinthidwa kukhala mtundu wotsekedwa, ntchito yosindikiza idzawirikiza kawiri. Makamaka, valavu yoyendetsera magawo awiri iyenera kugwiritsidwa ntchito molingana ndi mtundu wotsekedwa.

3. Sinthani njira yosindikizira ya mphamvu ya actuator

Kupititsa patsogolo mphamvu yosindikiza ya actuator ku spool ya valve ndi njira yodziwika bwino yotsimikizira kuti valve itsekedwa, kuonjezera kusindikiza kwapadera, ndi kupititsa patsogolo ntchito yosindikiza. Njira zodziwika bwino ndi izi:

① Kugwira ntchito kwa masika osuntha;

② Gwiritsani ntchito kasupe wouma pang'ono;

③ Onjezani zowonjezera, monga ndi malo;

④ Wonjezerani mphamvu ya mpweya;

⑤ Sinthani kukhala actuator yokhala ndi mphamvu yayikulu.

4. Uonani chisindikizo chimodzi, njira yosindikizira yofewa

Kwa valavu yoyang'anira yomwe imagwiritsidwa ntchito posindikiza pawiri, imatha kusinthidwa kukhala chisindikizo chimodzi, nthawi zambiri imatha kupititsa patsogolo kusindikiza kwa nthawi zopitilira 10, ngati mphamvu yosagwirizana ndi yayikulu, miyeso yofananira iyenera kuwonjezeredwa, valavu yosindikiza yolimba imatha kusinthidwa. kusindikiza kofewa,mongaVavu ya butterfly yokhazikika, ndipo amatha kusintha kusindikiza kopitilira nthawi zopitilira 10.

5. Gwiritsani ntchito valve yokhala ndi ntchito yabwino yosindikiza

Ngati ndi kotheka, lingalirani zosinthira ku valavu yokhala ndi ntchito yabwino yosindikiza. Ngati valavu yagulugufe wamba yasinthidwa kukhala valavu yagulugufe ya elliptical, ndiyeno imathanso kugwiritsa ntchito valavu yagulugufe yodulidwa,eccentric butterfly valve, valavu ya mpira ndi valavu yodulidwa mwapadera.

Ku Tianjin Tanggu Water Seal Valve Co., Ltd., timanyadira popereka zinthu zapamwamba zomwe zimakwaniritsa miyezo yapamwamba kwambiri yamakampani. Ndi ma valve athu osiyanasiyana ndi zomangira, mutha kutikhulupirira kuti tikupatsani yankho labwino kwambiri pamadzi anu. Lumikizanani nafe lero kuti mudziwe zambiri zazinthu zathu komanso momwe tingakuthandizireni.
