Mukufuna kuwongolera kuyenda kwa madzi mu chitoliro? Kusankha valavu yolakwika kungayambitse kutuluka kwa madzi, kulephera kwa makina, kapena kuwononga ndalama zosafunikira. Vavu ya mpira wa PVC ndi njira yosavuta komanso yodalirika yogwirira ntchito zambiri.

Valavu ya mpira wa PVC imagwiritsidwa ntchito makamaka poyendetsa/kutseka madzi m'makina amadzimadzi. Ndi yabwino kwambiri pa ntchito monga kuthirira, maiwe osambira, mapaipi, ndi mizere ya mankhwala yotsika mphamvu komwe mukufuna njira yachangu komanso yosavuta yoyambira kapena kuyimitsa kuyenda kwa madzi.

Ndimafunsidwa mafunso okhudza zinthu zofunika nthawi zonse, ndipo ndi zinthu zofunika kwambiri zomwe ndi izi. Sabata yatha, Budi, manejala wogula zinthu ku Indonesia, anandiyimbira foni. Mmodzi mwa ogulitsa ake atsopano anali kuyesera kuthandiza mlimi waung'ono ndikapangidwe ka ulimi wothiriraWogulitsayo anasokonezeka kuti angagwiritse ntchito liti valavu ya mpira poyerekeza ndi mitundu ina. Ndinamufotokozera kuti pogawa madera osiyanasiyana mu njira yothirira, palibe njira ina yabwino kuposaValavu ya mpira wa PVCNdi yotsika mtengo, yolimba, ndipo imapereka chizindikiro chowoneka bwino—chogwirira pa chitoliro chotseka, chogwirira pamzere chokhazikika. Kudalirika kosavuta kumeneku ndiko kumapangitsa kuti ikhale valavu yodziwika kwambiri m'mafakitale ambiri.

Kodi valavu ya mpira wa PVC imagwiritsidwa ntchito pa chiyani?

Mumawona valavu ya mpira wa PVC m'sitolo, koma imayikidwa kuti kwenikweni? Kugwiritsa ntchito molakwika, monga pa zakumwa zotentha kwambiri, kungayambitse kulephera nthawi yomweyo.

Vavu ya mpira wa PVC imagwiritsidwa ntchito makamaka powongolera kuyenda kwa madzi ozizira. Ntchito zodziwika bwino zimaphatikizapo dziwe losambira ndi mapaipi a spa, manifolds othirira, mipope ya m'nyumba, malo osungira madzi, ndi njira zotsukira madzi chifukwa cha kukana dzimbiri komanso mtengo wake wotsika.

Chinsinsi chomvetsetsa kagwiritsidwe ntchito ka valavu ya mpira wa PVC ndikudziwa mphamvu zake ndi zofooka zake. Mphamvu yake yayikulu ndi kukana kwake dzimbiri kuchokera ku madzi, mchere, ndi mankhwala ambiri ofala. Izi zimapangitsa kuti ikhale yoyenera kwambiri pamakina osambira omwe amagwiritsa ntchito chlorine kapena makonzedwe aulimi omwe angaphatikizepo feteleza. Ndi yopepuka komanso yosavuta kuyiyika pogwiritsa ntchito simenti yosungunulira, yomwe imachepetsa ndalama zogwirira ntchito. Komabe, choletsa chake chachikulu ndi kutentha. PVC yokhazikika si yoyenera mizere yamadzi otentha, chifukwa imatha kupindika ndikulephera. Nthawi zonse ndimakumbutsa Budi kuti aphunzitse gulu lake kuti afunse kaye za kutentha kwa ntchitoyo. Pa ntchito iliyonse yozizira yotsegula/kutseka madzi, valavu ya mpira wa PVC nthawi zambiri imakhala yankho labwino kwambiri. Imapereka chisindikizo cholimba komanso nthawi yayitali yogwira ntchito ikagwiritsidwa ntchito moyenera.

Madera Ofunika Kwambiri Ogwiritsira Ntchito

Kodi cholinga chachikulu cha valavu ya mpira ndi chiyani?

Muyenera kuwongolera kayendedwe ka madzi, koma pali mitundu yambiri ya ma valve. Kugwiritsa ntchito molakwika valavu, monga kuyesa kupotoza ndi valavu ya mpira, kungayambitse kutha ndi kutuluka madzi msanga.

Cholinga chachikulu cha valavu ya mpira ndikupereka kutseka/kutseka mwachangu komanso kodalirika. Imagwiritsa ntchito mpira wamkati wokhala ndi dzenje kudzera (bowo) lomwe limazungulira madigiri 90 ndi kutembenuza chogwirira kuti iyambe kapena kuyimitsa kuyenda nthawi yomweyo.

Kukongola kwavalavu ya mpirandi kuphweka kwake komanso kugwira ntchito kwake. Kachitidwe kake ndi kowongoka: pamene chogwirira chili chofanana ndi chitoliro, dzenje lomwe lili mu mpira limagwirizana ndi kayendedwe ka madzi, zomwe zimathandiza kuti madzi adutse momasuka. Apa ndiye malo "oyatsira". Mukatembenuza chogwirira madigiri 90, kotero chimakhala cholunjika ku chitoliro, mbali yolimba ya mpira imatseka kutsegula, ndikuletsa kutuluka kwa madzi. Apa ndiye malo "oyatsira". Kapangidwe kameneka ndi kabwino kwambiri potseka chifukwa kamapanga chisindikizo cholimba kwambiri. Komabe, sichinapangidwe kuti "chizimitse," kapena kusiya valavu yotseguka pang'ono kuti ilamulire kuyenda kwa madzi. Izi zingayambitse madzi oyenda mofulumira kuwononga mipando ya valavu pakapita nthawi, zomwe zimapangitsa kuti madzi atuluke. Pakuwongolera koyatsira/kuzima, ndi kwabwino kwambiri. Pakuwongolera kayendedwe ka madzi, valavu yozungulira ndi chida chabwino kwambiri pantchitoyi.

Kulamulira pa/kutseka vs. Kuchepetsa mphamvu

Kodi ma valve a mpira a PVC ndi abwino?

Mukuona mtengo wotsika wa valavu ya mpira wa PVC ndipo mumadzifunsa ngati ndi yabwino kwambiri kuti ikhale yoona. Kusankha valavu yotsika mtengo kungayambitse ming'alu, kusweka kwa chogwirira, komanso kuwonongeka kwakukulu kwa madzi.

Inde, ma valve apamwamba a mpira a PVC ndi abwino kwambiri komanso odalirika kwambiri pa ntchito yawo. Chofunika kwambiri ndi khalidwe labwino. Valavu yopangidwa bwino yopangidwa ndi PVC yopanda zingwe yokhala ndi mipando ya PTFE ndi mphete ziwiri za O-rings zidzapereka chithandizo cha zaka zambiri chopanda kutayikira m'njira yoyenera.

Apa ndi pomwe luso lathu lopanga zinthu ku Pntek limagwira ntchito. Si ma valve onse a PVC omwe amapangidwa mofanana. Ma valve otsika mtengo nthawi zambiri amagwiritsa ntchito "regrind" kapena PVC yobwezeretsedwanso, yomwe ingakhale ndi zodetsa zomwe zimapangitsa kuti thupi la valve likhale lofooka. Angagwiritse ntchito zomatira za rabara zochepa zomwe zimawonongeka mwachangu, zomwe zimapangitsa kuti pakhale kutuluka kwa madzi pa tsinde la chogwirira. Valavu ya PVC "yabwino", monga yomwe timapanga, imagwiritsa ntchitoUtomoni wa PVC wa 100% wosasinthikakuti mukhale ndi mphamvu zambiri. Timagwiritsa ntchito mipando ya PTFE (Teflon) yolimba yomwe imapanga chisindikizo chosalala komanso chokhalitsa motsutsana ndi mpirawo. Timapanganso ma valvu athu okhala ndi ma O-rings awiri kuti apereke chitetezo chowonjezera ku kutuluka kwa madzi. Ndikamalankhula ndi Budi, ndimagogomezera kuti kugulitsa valavu yabwino sikungokhudza chinthu chokhacho; koma kupatsa makasitomala ake mtendere wamumtima ndikupewa kulephera kokwera mtengo komwe kukubwera.

Zizindikiro za Valavu Yabwino ya Mpira wa PVC

Kodi cholinga cha valavu yoyezera ya PVC ndi chiyani?

Mukudziwa kuti valavu ya mpira imasiya kuyenda mukayitembenuza, koma n’chiyani chimasiya kuyenda yokha? Ngati madzi abwerera m’mbuyo, akhoza kuwononga pampu kapena kuipitsa madzi anu popanda inu kudziwa.

Cholinga cha valavu yoyezera ya PVC ndikuletsa madzi kubwerera m'mbuyo okha. Ndi valavu yolowera mbali imodzi yomwe imalola madzi kuyenda patsogolo koma imatseka nthawi yomweyo ngati madzi abwerera m'mbuyo. Imagwira ntchito ngati chipangizo chofunikira kwambiri chotetezera, osati valavu yowongolera ndi manja.

Ndikofunikira kumvetsetsa kusiyana pakati pa valavu ya mpira ndivalavu yoyezera. Vavu ya mpira ndi yowongolera ndi manja—mumasankha nthawi yoyatsira kapena kuzimitsa madzi. Vavu yowunikira ndi yodzitetezera yokha. Tangoganizirani pampu ya sump yomwe ili pansi pa nyumba. Pampu ikayatsa, imatulutsa madzi. Kuyenda kwa madzi kumatsegula valavu yowunikira. Pampu ikazima, mzati wa madzi mu chitoliro umafuna kubwerera m'chipinda chapansi pa nyumba. Chophimba chamkati cha valavu yowunikira chimagwedezeka nthawi yomweyo kapena kutseka, zomwe zimaletsa zimenezo kuti zisachitike. Vavu ya mpira imafuna munthu woti aigwiritse ntchito; valavu yowunikira imagwira ntchito yokha, yoyendetsedwa ndi kuyenda kwa madzi okha. Ndi zida ziwiri zosiyana za ntchito ziwiri zosiyana kwambiri, koma zofunika kwambiri, mu dongosolo la mapaipi.

Valavu ya Mpira vs. Valavu Yowunikira: Kusiyana Komveka

Mapeto

Ma valve a mpira wa PVCndi muyezo wodalirika, wowongolera ndi kuzimitsa pamanja m'makina amadzi ozizira. Kuti mupewe kubwereranso kwa madzi, valavu yowunikira ndiye chipangizo chofunikira kwambiri chotetezera chomwe mukufuna.
