Mfundo za kusankha mavavu mankhwala

Mitundu ndi ntchito za mavavu amankhwala

Kutsegula ndi kutseka mtundu: kudula kapena kulankhulana ndi kutuluka kwa madzi mu chitoliro; mtundu wa malamulo: sinthani kuyenda ndi kuthamanga kwa chitoliro;

Mtundu wa Throttle: kupanga madzimadzi kutulutsa kutsika kwakukulu pambuyo podutsa valavu;

Mitundu ina: a. Kutsegula ndi kutseka basi b. Kukhalabe ndi chitsenderezo china c. Kutsekereza nthunzi ndi ngalande.

Mfundo za kusankha vavu mankhwala

Choyamba, muyenera kumvetsetsa ntchito ya valve. Chachiwiri, muyenera kudziwa masitepe ndi maziko osankha valve. Pomaliza, muyenera kutsatira mfundo za kusankha mavavu m'mafakitale mafuta ndi mankhwala.

Mavavu amakhemikali nthawi zambiri amagwiritsa ntchito zida zomwe zimakhala zosavuta kuwononga. Kuchokera kumakampani osavuta a chlor-alkali kupita kumakampani akuluakulu a petrochemical, pali zovuta monga kutentha kwambiri, kuthamanga kwambiri, kuwonongeka, kosavuta kuvala, komanso kutentha kwakukulu ndi kupanikizika. Valavu yomwe imagwiritsidwa ntchito pamtundu uwu wa chiopsezo chachikulu iyenera kutsatiridwa mosamalitsa malinga ndi miyezo yamankhwala pakusankha ndi kugwiritsa ntchito.

M'makampani opanga mankhwala, ma valve okhala ndi njira zowongoka zowongoka nthawi zambiri amasankhidwa, omwe amakhala otsika kukana. Nthawi zambiri amagwiritsidwa ntchito ngati ma valve otseka komanso otseguka. Mavavu omwe ndi osavuta kusintha mayendedwe amagwiritsidwa ntchito powongolera kuyenda. Mavavu omangira ndi ma valve a mpira ndi oyenera kubweza ndi kugawa. , Valavu yokhala ndi zotsatira zopukuta pa kutsetsereka kwa membala wotseka pambali yosindikizira ndi yabwino kwambiri kwa sing'anga yokhala ndi particles zoimitsidwa. Ma valves odziwika bwino amaphatikizapo ma valve a mpira, ma valve a zipata, ma valve a globe, ma valve otetezera, ma valve a pulagi, ma check valves ndi zina zotero. Mitundu yambiri yamagetsi yamagetsi imakhala ndi mankhwala, ndipo pali zinthu zambiri zowononga acid-base. Zida za valve za mankhwala a fakitale ya Taichen makamaka 304L ndi 316. Media wamba imasankha 304 monga zinthu zotsogola. Madzi owonongeka ophatikizidwa ndi zinthu zingapo zamakemidwe amapangidwa ndi chitsulo cha alloy kapena valavu yokhala ndi Fluorine.

Chenjerani musanagwiritse ntchito mavavu amankhwala

① Kaya pali zolakwika monga matuza ndi ming'alu mkati ndi kunja kwa valavu;

②Kaya mpando wa valavu ndi thupi la valavu zalumikizidwa mwamphamvu, ngati valavu ndi mpando wa valve ndizofanana, komanso ngati malo osindikizira ali ndi vuto;

③Kaya kugwirizana pakati pa tsinde la valavu ndi pakati pa valavu kumasinthasintha komanso kodalirika, kaya tsinde la valve ndi lopindika, komanso ngati ulusi wawonongeka.
