Pali kusiyana koonekeratu pakati pa ma slide gate mavavu ndimpeni mavavu pachipatamalingana ndi kamangidwe, ntchito ndi zochitika zogwiritsira ntchito:

1. Mapangidwe apangidwe

Chipata cha valve yolowera chipata chimakhala chophwanyika, ndipo malo osindikizira nthawi zambiri amapangidwa ndi alloy yolimba kapena mphira. Kutsegula ndi kutseka kumatheka ndi kutsetsereka kopingasa kwa chipata pampando wa valve. Mapangidwewo ndi ovuta, ndipo ntchito yosindikiza imadalira kulondola koyenera pakati pa chipata ndi mpando wa valve.

Chipata cha valavu ya chipata cha chitsulo chopangira chitsulo chimakhala ngati tsamba, chomwe chimatha kudula ulusi, tinthu tating'onoting'ono ndi zonyansa zina mkatikati. Ili ndi mawonekedwe ophatikizika. Malo osindikizira pakati pa chipata ndi mpando wa valve nthawi zambiri amapangidwa ngati kukhudzana kwachitsulo cholimba, chomwe chimakhala ndi kukana kolimba.

2. Kusindikiza ntchito

Valavu yachipata chotsetsereka imakhala ndi ntchito yabwino yosindikiza ndipo ndiyoyenera makamaka pazochitika zomwe zimakhala ndi zofunika kwambiri zotayikira (monga media media). Zitsanzo zina zimakhala ndi mawonekedwe osindikizira awiri.

Kusindikiza kwa valavu ya chipata cha mpeni wa flange kumayang'ana kwambiri zotsutsana ndi kuvala ndipo ndizoyenera zofalitsa zomwe zimakhala ndi tinthu tating'onoting'ono, slurry, ndi zina zotero. Malo osindikizira amatha kukonzedwa ndikupera, koma kutayikirako kumakhala kwakukulu pang'ono kusiyana ndi valavu ya chipata cha slide plate.

3. Zochitika za Ntchito

Ma valve olowera pachipata amagwiritsidwa ntchito kwambiri poyeretsa zinthu monga gasi ndi mafuta, kapena pamapaipi omwe amafunikira kusindikizidwa mwamphamvu.

Vavu yamagetsi yamagetsi ndi yabwino kwambiri pazofalitsa zomwe zimakhala ndi zonyansa monga zimbudzi, zamkati, ndi ufa wa malasha, ndipo zimagwiritsidwa ntchito m'magawo monga zitsulo, migodi, ndi kuteteza chilengedwe.

Vavu ya Jinbin imagwira ntchito bwino popanga ndikusintha makonda a mavavu a pachipata cha mpeni wokhala ndi m'mimba mwake. Vavu yachipata chachikulu cha mpeni (yokhala ndi mainchesi ≥DN300) imagwiritsidwa ntchito kwambiri m'mapaipi akumafakitale chifukwa cha kapangidwe kake komanso magwiridwe antchito.

Chipata chopangidwa ndi mpeni chimatha kudula mosavuta ulusi, tinthu tating'onoting'ono kapena zinthu zowoneka bwino (monga slurry, zamkati) pakati, kuteteza zonyansa kuti zisachulukane ndikutsekereza valavu. Ndizoyenera kwambiri kunyamula media okhala ndi zinthu zolimba zoyimitsidwa, kuchepetsa kuchuluka kwa kukonza mapaipi.

2. Thupi la valve limagwiritsa ntchito ndondomeko yowongoka, yomwe imakhala ndi kukana kwamadzi otsika komanso kutsegula pang'ono ndi kutseka kwa chipata. Ikaphatikizidwa ndi magetsi kapena ma pneumatic actuators, imatha kutsegulira ndi kutseka mwachangu, kuchepetsa kuvutikira kwa ma valve akulu akulu ndikupangitsa kuti ikhale yoyenera pazowongolera zokha.

3. Malo osindikizira nthawi zambiri amapangidwa ndi aloyi yolimba kapena chitsulo chosamva kuvala, chomwe chimakhala ndi mphamvu zotsutsana ndi kukokoloka. Ngakhale atagwiritsidwa ntchito kwa nthawi yayitali pamayendedwe okwera kwambiri kapena pama media okhala ndi tinthu tating'onoting'ono, amatha kukhalabe osindikiza bwino ndikuchepetsa ndalama zosinthira.

4. Thupi la valve liri ndi mawonekedwe ophweka, ndi opepuka kulemera kuposa mitundu ina ya ma valve omwe ali ndi mainchesi ofanana, ndipo ali ndi zofunikira zochepa zothandizira mapaipi panthawi yoika. Mpando wa chipata ndi valavu ukhoza kugawidwa ndikusinthidwa mosiyana. Panthawi yokonza, palibe chifukwa chosinthira valve yonseyo, kuchepetsa ndalama zothandizira.

5. Ikhoza kusinthasintha ndi kutentha kwakukulu, kuthamanga kwambiri ndi zowononga zowonongeka (monga madzi otayira a mankhwala, acidic slurry). Posankha zipangizo zosagwirizana ndi dzimbiri (monga zitsulo zosapanga dzimbiri, zokhala ndi mphira), zimatha kukumana ndi zovuta zogwirira ntchito za mafakitale osiyanasiyana ndipo zimakhala ndi mphamvu zambiri.

Ngati muli ndi zosowa zina, chonde titumizireni pansipa ndipo mudzalandira yankho mkati mwa maola 24!
