Pogula mavavu agulugufe, nthawi zambiri timamva mawu agulugufe wokhazikika komanso valavu yagulugufe wopanda pinless.Chifukwa chaukadaulo, valavu yagulugufe yopanda pinless nthawi zambiri imakhala yokwera mtengo kuposa valavu yagulugufe yopanda pinless, zomwe zimapangitsa makasitomala ambiri kuganiza ngati valavu yagulugufe yopanda pinless ndi yokwera mtengo kuposa valavu yagulugufe yopanda pinless.Kodi valavu ya gulugufe ili bwino?Nanga bwanji kufananitsa valavu yagulugufe yokhomedwa ndi valavu yagulugufe yopanda pinless?
Kuchokera pamawonekedwe, kusiyana kofunikira kwambiri pakati pa valavu yagulugufe wokhomedwa ndi valavu yagulugufe wopanda pinless ndi: kaya pali pini yopindika pa valavu.Kulumikizana pakati pa mbale ya valve ndi tsinde la valavu ndi pini ndi valavu ya butterfly ya pini, ndipo mosiyana ndi valavu yagulugufe yopanda pinless.Kwa mavavu agulugufe okhomedwa ndi mavavu agulugufe opanda pinless, ali ndi zabwino ndi zovuta zawo.
Mkhalidwe Weniweni Ndi Motere:
Kuyerekeza kwa mawonekedwe - valavu yagulugufe yokhomedwa imakhala ndi mawonekedwe amtundu wa pini pamawonekedwe, omwe sakhala osalala komanso okongola ngati valavu yagulugufe yopanda pinless, koma ilibe kukhudzidwa kwakukulu pamawonekedwe onse.
Kuyerekeza kwa njira - kapangidwe kake ndi kachitidwe ka pini butterfly valve kudzakhala kosavuta, koma ngati kukonza kumafunika pakagwiritsidwa ntchito nthawi yayitali, zimakhala zovuta kwambiri kusokoneza shaft ndi mbale ya valve.Sikophweka kuchotsa tsinde la valve chifukwa zikhomo nthawi zambiri zimagundidwa zimawunjidwa ndikukanikizidwa mwamphamvu ndi makina osindikizira.Valavu yagulugufe yopanda pinless idzakhala yovuta kwambiri pamapangidwe ndi ukadaulo chifukwa cha njira zosiyanasiyana zotumizira ma torque, koma kukonza ndi kuphatikizira pambuyo pake kumakhala kosavuta komanso kosavuta kukonza.
Kuyerekeza kukhazikika - Mavavu agulugufe okhala ndi zikhomo amakhala okhazikika kuposa omwe alibe mapini chifukwa amamangidwa ndi mapini.Mapangidwe opanda pini amakhudza kulondola kwa zochitika chifukwa cha kuvala kwa mating pamwamba pa shaft ndi chipata pambuyo pakuchitapo kwa nthawi yaitali.
Kufananitsa Kusindikiza - Pomaliza, tiyeni tiwone kufananitsa kwa kusindikiza.Pali mawu akuti pogwiritsira ntchito valavu ya butterfly yokhala ndi pini, sing'angayo imatha kulowa kuchokera pamalo pomwe pini imakhomedwa pakati pa mbale ya valve ndi tsinde la valve.Choopsa chobisika chomwe chimabwera chifukwa cha izi ndikuti piniyo imakhala ndi dzimbiri ndipo imasweka pakapita nthawi yayitali, zomwe zimapangitsa kuti valavu isagwire ntchito, kapena vuto la ejector kutayikira kapena kutulutsa mkati mwa payipi.
Mwachidule, kufananiza valavu yagulugufe yokhomedwa ndi valavu yagulugufe yopanda pinless, kunena moona mtima, mapangidwe aliwonse ali ndi mawonekedwe ake ndi zabwino zake, ndipo sizingatheke kungonena zomwe zili bwino.Malingana ngati tisankha mankhwala oyenera kwambiri pa bajeti yathu yamtengo wapatali komanso momwe timagwirira ntchito, ndi chinthu chabwino kwa ife.
