Monga momwe mukudziwira kale, valavu ya butterfly ndi valve yozungulira kotala yokhala ndi mpando wooneka ngati disc. Diskiyo ndi perpendicular kwa madzimadzi pamene valavu yatsekedwa ndi kufanana ndi madzimadzi pamene valavu yatseguka. Ma valve awa amayendetsedwa ndi lever, magiya kapena makina / pneumatically actuated. Ngakhale kuti ma valve a gulugufe ndi osavuta, anthu ambiri sadziwa mitundu yosiyanasiyana ya ma valve a butterfly yomwe ilipo.

Ndi kusankha ma valve a butterfly, monga mitundu yosiyanasiyana ya thupi, zipangizo ndi njira zogwirira ntchito, pali mitundu yambiri ya ma valve a butterfly yomwe mungasankhe. Choyamba, tiyeni tione mitundu yosiyanasiyana ya thupi, kenako tikambirane za zipangizo ndi mmene tingachitire. Zinthu izi zimakuuzani zomwe valve imachita. Kusankha avalavu ya butterflychifukwa ntchito yanu ikhoza kukhala yovuta, ndiye tiyesetsa kupangitsa zinthu kukhala zosavuta ndi positi iyi yabulogu!

Mtundu wa thupi la butterfly valve
Ma valve a butterfly ndi otchuka chifukwa cha mapangidwe awo otsika. Zimakhala zoonda ndipo nthawi zambiri zimatenga malo ocheperako mupaipi kuposa mavavu a mpira. Mitundu iwiri ikuluikulu ya mavavu agulugufe amasiyana m'mene amamatira ku chitoliro. Maonekedwe a thupi awa ndi masitayelo a lug ndi ma wafer. Kodi pali kusiyana kotani pakati pa ma valve a butterfly a lug ndi wafer? Werengani kuti mudziwe.

Vavu yagulugufe wa lug (yomwe ili pansipa) imagwira ntchito ngati valavu yeniyeni ya mpira. Amalola mapaipi oyandikana nawo kuti achotsedwe pamene dongosololi likugwirabe ntchito. Mavavuwa amachita izi pogwiritsa ntchito magulu awiri a mabawuti, seti imodzi ku flange iliyonse yoyandikana nayo. Maboti otsala amasunga chisindikizo cholimba pakati pa valavu ndi chitoliro. Ma valve agulugufe a Lug ndi abwino kwa mapulogalamu omwe amafunikira kuyeretsedwa pafupipafupi komanso kukonza kwina.

Zida za valve butterfly
Monga mitundu ina ya mavavu, mavavu agulugufe amabwera muzinthu zosiyanasiyana. Kuchokera kuzitsulo zosapanga dzimbiri kupita ku PVC, zosankhazo ndizopanda malire. Komabe, pali zida zina zomwe zimatchuka kwambiri, ndiye tiyeni tiwone!

PVC ndi chitsulo chotayidwa ntchito zosiyanasiyana mavavu gulugufe PVC ndi imodzi mwa mapulasitiki ambiri agulugufe mavavu. Makhalidwe ochepa amawapangitsa kukhala abwino kwa mapulogalamu ambiri otsika mpaka apakatikati. Choyamba, iwo ndi opepuka pomwe amakhalabe ndi umphumphu wochititsa chidwi. Chachiwiri, ali ndi kugwirizana kwakukulu kwa mankhwala kuposa zitsulo zambiri. Pomaliza, onse a PVC ndi CPVC ndi otsika mtengo poyerekeza ndi anzawo achitsulo. Dinani ulalo kuti muwone mitundu yathu yambiri ya PVC Butterfly Valves kapena CMavavu a Gulugufe a PVC!

Chitsulo chachitsulo ndi chitsulo chosankhika pamavavu agulugufe. Chitsulo chotayira chimakhala ndi kukhulupirika komanso kutentha kwambiri kuposa PVC kapena CPVC, zomwe zimapangitsa kukhala chisankho chabwino kwambiri pamachitidwe amakampani omwe amafunikira kulimba kwambiri. Pakati pa zitsulo, chitsulo ndi njira yotsika mtengo, koma izi sizikutanthauza kuti ndizosathandiza. Mavavu agulugufe otayira ndi osunthika motero ndi abwino kugwiritsa ntchito zosiyanasiyana.
