Mufunika valavu ya mpira yotsika mtengo, koma zosankhazo ndizosokoneza. Kusankha mtundu wolakwika kumatanthauza kuti mutha kukhala ndi kutayikira kosatha, kosasinthika kukalephera.

Kusiyana kwakukulu ndikumanga: avalavu imodziali ndi thupi lolimba, lopanda msoko, pamene avalavu iwiriali ndi thupi lopangidwa kuchokera ku ziwalo ziwiri zopindidwa pamodzi. Onsewa amaonedwa kuti sangakonzedwenso, mavavu otaya omwe amapangidwira ntchito zosavuta.

Izi zitha kuwoneka ngati zazing'ono zamaukadaulo, koma zimakhala ndi tanthauzo lalikulu pa amphamvu ya valve, mlingo wotuluka, ndi zolephera zomwe zingatheke. Ili ndi lingaliro lofunikira lomwe ndimakambirana nthawi zonse ndi anzanga, monga Budi, woyang'anira zogula ku Indonesia. Ayenera kupereka valavu yoyenera kuti agwire ntchito yoyenera, kaya ndi ntchito yosavuta yapakhomo kapena ntchito yovuta ya mafakitale. Kumvetsetsa momwe ma valvewa amamangidwira kudzakuthandizani kusankha yomwe ikugwirizana ndi zosowa zanu, komanso pamene muyenera kupita ku yankho la akatswiri.

Kodi kupanga valavu ya 1-chidutswa cha 2 kumakhudza bwanji ntchito?

Mukuwona msoko pa valve yazigawo ziwiri ndikudandaula kuti ndi malo ofooka. Koma ndiye mukudabwa ngati mawonekedwe osasunthika a chidutswa chimodzi ali ndi zovuta zake zobisika.

Thupi lolimba la valavu imodzi lilibe misonkho, zomwe zimapangitsa kuti likhale lolimba kwambiri. Komabe, nthawi zambiri imakhala ndi doko lochepetsedwa. Valavu yokhala ndi magawo awiri imatha kupereka doko lathunthu koma imayambitsa msoko wopangidwa ndi ulusi, ndikupanga njira yodutsira.

Kusinthanitsa kwa magwiridwe antchito kumabwera mwachindunji momwe amapangidwira. Valve yachidutswa chimodzi ndi yosavuta komanso yamphamvu, koma mpirawo uyenera kulowetsedwa kupyolera mu umodzi wa mapeto, zomwe zikutanthauza kuti kutsegula kwa mpira (doko) kuyenera kukhala kochepa kusiyana ndi kugwirizana kwa chitoliro. Izi zimalepheretsa kuyenda. Valavu yokhala ndi zigawo ziwiri imamangidwa mozungulira mpirawo, kotero kuti doko likhoza kukhala lalikulu lonse la chitoliro. Uwu ndiye mwayi wake waukulu. Komabe, msoko wa thupilo, womwe umagwirizanitsidwa ndi ulusi, ndi chinthu chofunikira kwambiri chomwe chingalephereke. Pansi pa kupsinjika ndi ma spikes kapena nyundo yamadzi, msokowu ukhoza kutuluka. Kwa wogula ngati Budi, kusankha kumatengera zomwe kasitomala akufuna: mtheradi wadongosologawo limodzipa ntchito yotsika kwambiri, kapena kuthamanga kwapamwamba kwa azidutswa ziwiri, ndi chiwopsezo chokhudzana ndi kutayikira.

Kuchita Pang'onopang'ono

Kodi pali kusiyana kotani pakati pa chidutswa chimodzi ndi valavu yamagulu atatu?

Ntchito yanu imafuna kudalirika kwa nthawi yayitali. Valve yotsika mtengo yachidutswa chimodzi ndi yoyesa, koma mukudziwa kuti nthawi yopumira poidula kuti m'malo mwake ikhale tsoka.

Valve yachidutswa chimodzi ndi yosindikizidwa, yotayika yomwe imayikidwa kwamuyaya. Avalavu yowona yamagulu atatundi njira yaukadaulo yomwe imatha kuchotsedwa papaipi kuti ikonzedwe mosavuta kapena kuyisintha popanda kudula chitoliro.

Uku ndiye kufananitsa kofunikira kwambiri pantchito iliyonse yaukadaulo. Filosofi yonse ndi yosiyana. Valve yachidutswa chimodzi idapangidwa kuti iziyika kamodzi ndikutayidwa ikalephera. Valve yokhala ndi magawo atatu idapangidwa kuti ikhale gawo lokhazikika la dongosolo lomwe lingasungidwe kosatha. Nthawi zonse ndimagawana izi ndi Budi kwa makasitomala ake pazaulimi komanso kukonza mafakitale. Kutayikira mu machitidwe awo kungakhale koopsa. Ndi valavu yachidutswa chimodzi, amakumana ndi kutsekedwa kwanthawi yayitali kuti alowe m'malo mosokoneza. Ndi Pntek ya magawo atatuvalavu ya mgwirizano weniweni, akhoza kumasula awiriwomtedza wa mgwirizano, kwezani thupi la valavu kunja, lowetsani mu thupi lolowa m'malo kapena zida zosavuta zosindikizira, ndikuthamanga kachiwiri mu mphindi zisanu. Mtengo wokwera pang'ono umalipidwa kambirimbiri popewa ola limodzi lopumira. Ndi ndalama zogwirira ntchito bwino.

Kodi valve yachidutswa chimodzi ndi chiyani kwenikweni?

Mufunika valavu yotsika mtengo kwambiri kuti mugwire ntchito yosavuta. Mapangidwe amtundu umodzi amawoneka ngati yankho, koma muyenera kudziwa malire ake musanapereke.

Valavu yamtundu umodzi imapangidwa kuchokera ku pulasitiki imodzi yolimba. Mpira ndi mipando imalowetsedwa kumapeto, ndipo tsinde ndi chogwirira zimayikidwa, kupanga chisindikizo chosindikizidwa, chosakonzedwanso popanda thupi.

Njira yomanga iyi imaperekavalavu imodzikufotokozera kwake. Mphamvu yake yayikulu ndiyopanda nsonga za thupi, zomwe zikutanthauza kuti malo amodzi ocheperako amatayikira. Ndiwosavuta komanso yotsika mtengo kupanga. Izi zimapangitsa kukhala chisankho chabwino pazinthu zosafunikira, zotsika kwambiri zomwe sizidzagwiritsidwa ntchito nthawi zambiri, monga chingwe choyambira. Komabe, kufooka kwake kwakukulu ndi "doko lochepetsedwa"Kupanga. Chifukwa zigawo zamkati ziyenera kukwanira pabowo lolumikizira chitoliro, kutsegulira kwa mpira kumakhala kocheperako kuposa kukula kwa chitoliro chamkati. Izi zimapanga mikangano ndikuchepetsa kuthamanga kwa dongosolo lonse. Ndikufotokozera anzanga kuti izi ndi zabwino kwa makasitomala awo ogulitsa omwe akuchita mapulojekiti osavuta a DIY, koma siwosankha bwino pamakina aliwonse omwe kuyenda kwakukulu ndi kugwirira ntchito ndikofunikira.

Kotero, chimatanthauza chiyani valavu ya zidutswa ziwiri?

Vavu iyi ikuwoneka ngati yakhazikika pakati. Siyotsika mtengo, komanso si yothandiza kwambiri. Mukutsala pang'ono kudabwa chifukwa chake ilipo komanso cholinga chake chenicheni.

Valavu yokhala ndi magawo awiri imatanthauzidwa ndi thupi lake, lomwe limapangidwa kuchokera ku zigawo ziwiri zomwe zimalumikizana. Kapangidwe kameneka kamapangitsa kukhala ndi doko lalikulu pamtengo wotsika, koma kumapanga msoko wokhazikika, wosagwiritsidwa ntchito.

Thevalavu iwiriadapangidwa kuti athetse vuto limodzi: kutsekeka kwa valve yachidutswa chimodzi. Popanga thupi m'magawo awiri, opanga amatha kulumikiza valavu kuzungulira mpira wokulirapo wokhala ndi doko lokwanira, lofanana ndi mainchesi amkati a chitoliro. Izi zimapereka mawonekedwe abwino kwambiri othamanga pamtengo wamtengo pansi pa valve yamagulu atatu. Uwu ndiye mwayi wake weniweni. Komabe, ubwino umenewo umabwera pamtengo. Msoko wa ulusi womwe umagwirizanitsa magawo awiriwa ndi chinthu chofooka. Sizinapangidwe kuti zipatulidwe kuti zigwiritsidwe ntchito, choncho ndi valavu "yotaya". Kwa anzanga, ndimayiyika ngati chinthu chamtengo wapatali. Ngati kasitomala awo mwamtheradi akusowakutuluka kwathunthukoma sangakwanitse kugula valavu yamagulu atatu, magawo awiriwa ndi osankha, koma ayenera kuvomereza kuwonjezeka kwa chiwopsezo cha kutayikira pa msoko wa thupi pakapita nthawi.

Mapeto

Mavavu amtundu umodzi ndi awiri onse ndi mapangidwe osagwiritsidwa ntchito. Chisankho chabwino kwambiri chimadalira kusinthasintha kwa kayendedwe kake (ziwiri-ziwiri) motsutsana ndi umphumphu wa thupi (chidutswa chimodzi), ndipo zonsezi ndi zotsika kwa valve ya zidutswa zitatu.
