Zikafika kudziko lazamalonda agulugufe mavavu, si zida zonse zomwe zimapangidwa mofanana. Pali kusiyana kwakukulu pakati pa njira zopangira ndi zida zomwe zimasintha zomwe zimasintha komanso kuthekera kwambiri. Kuti akonzekere bwino kusankha, wogula ayenera kuphunzira ukadaulo ndi kusiyanasiyana kwamitundu yosiyanasiyana kuti asankhe bwino chipangizo chawo.
1.Kupanga Mavavu a Butterfly
Zomangamanga za valve zimatsimikizira mphamvu zake ndi moyo wautali. Mavavu omwe amapangidwira kuti azithamanga kwambiri, kuthamanga kwambiri, komanso kugwiritsidwa ntchito kwa nthawi yayitali, makamaka kumadera akutali, nthawi zambiri amapangidwa ndi chitsulo cholimba kapena cholimba. Mabaibulo ena omwe amapangidwira ntchito yopepuka kapena kugwiritsa ntchito kwakanthawi kochepa amapangidwa ndi zinthu monga aloyi wopepuka, aluminiyamu, kapena pulasitiki ya PVC. Mavavu apamwamba kwambiri amapangidwa kuti athe kupirira zovuta zolimbana ndi kuthamanga kwambiri, kunyamula zinthu zofunikira kwambiri, komanso kukhala ndi kulimba kofunikira kuti agwiritsidwe ntchito kwa nthawi yayitali. Pazida zomwe zili m'malo ovuta kufikako kapena zokwiriridwa pansi pa nthaka, valavu yokhazikika ndiyofunikira. Ndalama zofikira chipangizo choterechi kuti zilowe m'malo nthawi zambiri zimakhala zakuthambo, choncho kuyika ndalama mu valve yapamwamba kwambiri kuyambira pachiyambi ndi chisankho chanzeru.
2.Enieni Mapulogalamu
Kusankha valavu molingana ndi ntchito inayake ndikofunikira. Zina ndi zopepuka ndipo zimapangidwira njira zazing'ono zamadzi kapena zowongolera mafuta. Malo okhala m'madzi, maiwe, ndi makina owaza ndi zitsanzo zabwino za ntchito yopepuka, yosafunikira kwambiri pamavavu agulugufe.
Mapulogalamu ofunikira kwambiri monga mapaipi a gasi, kayendedwe ka mafuta kapena makina osinthira madzi amzinda wothamanga kwambiri amafunikira ma valve apamwamba kwambiri, odalirika okhala ndi moyo wautali. Zida zolemetsazi zimayesedwa ndi fakitale kuti zigwire ntchito ndi kudalirika, kuti zikwaniritse ndi kupitirira zofunikira za ntchito zofunika kwambiri.
Zolemba za wopanga zimatha kuwulula tsatanetsatane wa mphamvu za valve iliyonse. Kusankha valavu yoyenera pa ntchitoyo n'kofunika kwambiri kuti mugwiritse ntchito nthawi yayitali ndi kuchepetsa mwayi wolephera makina.
3.Mulingo wa Precision
Chinthu chinanso chofunikira pakusankha vavu kuti mugwiritse ntchito ndi kuchuluka kwa kulondola komwe kwapangidwira mu chipangizocho. Valavu iliyonse imakhala ndi zidziwitso za kuchuluka kwa kutayikira, ngati kulipo, pamalo otsekera, momwe gawolo lilili, kuchuluka kwamadzimadzi komwe kumatha kutsegulidwa kwathunthu, komanso momwe valavuyo imakhala yodalirika nthawi yayitali. Zolemba zimafotokozanso za liwiro la ntchito ya valve, yabwino nthawi yomwe magwiridwe antchito amafunikira.
4.Kuwongolera Zosankha
Chotsatira chofunikira pakusankha valavu ya ntchito yoperekedwa ndi njira yoyendetsera. Ma valve ena amaphatikizapo lever kapena chogwirira, chomwe chimapangidwa kuti chizisinthidwe pamanja kuchoka kutseguka kupita kutsekedwa. Chogwirizira chimakhala ndi kotala lakuyenda kuchokera kumapeto mpaka kumapeto, kuti musinthe mwachangu komanso mophweka ma valve. Zina zidapangidwa kuti zizingochitika zokha pogwiritsa ntchito makina osinthira makina monga solenoid kapena kuyenda kwamakina ena.
Ma valve otsogola kwambiri amaphatikiza makina owongolera amagetsi amagetsi. Galimoto iyi imatembenuza tsinde la valavu mwachindunji kapena kusuntha lever pogwiritsa ntchito mkono wa actuator. Kapena imapereka chiwongolero chonse kuchokera kudera lakutali ndipo ingagwiritsidwe ntchito kusinthira kuwongolera kolondola ngati kuli kofunikira.
5.Mphamvu ya Vavu
Chomaliza posankha valavu ndi mphamvu ya chipangizocho. Izi zikuphatikizapo kuchulukirachulukira kwa kuchuluka kwa zinthu zomwe zimadutsa mu valve mu nthawi yoperekedwa, komanso kuchuluka kwa mphamvu yamkati yomwe valve imatha kupirira bwinobwino. Pazida zothamanga kwambiri komanso zolemetsa, valavu yayikulu, yapamwamba imafunikira, yokhala ndi makulidwe oyenera kuti agwirizane ndi chitoliro cholumikizidwa. Onetsetsani kuti muyang'ane zotsutsana ndi zosowa zanu kuti mutsimikizire kuti valve ili ndi mphamvu zokwanira zogwiritsira ntchito.
