Mwaika mosamala valavu yatsopano ya PVC, koma ikutsika pang'onopang'ono kuchokera ku ulusi. Kuchilimbitsa kwambiri kumakhala kowopsa, monga mukudziwa kuti kutembenuka kumodzi kumatha kusokoneza koyenera.

Kuti muyike bwino valavu ya mpira wa PVC, kukulunga ulusi wamphongo ndi zigawo za 3-4 za tepi ya Teflon. Nthawi zonse kukulunga kumbali yomangitsa. Kenako, kulungani m'manja, ndipo gwiritsani ntchito wrench kwa nthawi imodzi kapena ziwiri zomaliza.

Ulusi wotayikira ndi chimodzi mwazolephera zodziwika bwino komanso zokhumudwitsa pakuyika. Nthawi zambiri zimachitika chifukwa cholakwitsa pang'ono, chomwe chingapeweke pokonzekera kapena kumangitsa. Nthawi zambiri ndimakambirana izi ndi mnzanga ku Indonesia, Budi, chifukwa ndi mutu wokhazikika makasitomala ake amakumana nawo. Kulumikizana kotetezedwa, kopanda kutayikira ndikosavuta kupeza. Mukungoyenera kutsatira njira zingapo zosavuta, koma zovuta kwambiri. Tiyeni tiyankhe mafunso ofunikira kuti tikonze nthawi iliyonse.

Momwe mungayikitsire zitoliro za PVC za ulusi?

Munagwiritsa ntchito phala losindikizira ulusi lomwe limagwira ntchito bwino pazitsulo, koma kuyika kwanu kwa PVC kumatulukabe. Choipa kwambiri, mumadandaula kuti mankhwala omwe ali mu phala angawononge pulasitiki pakapita nthawi.

Pa PVC ya ulusi, nthawi zonse gwiritsani ntchito tepi ya Teflon m'malo mwa chitoliro kapena phala. Manga ulusi wachimuna 3-4 nthawi yomweyo mulimbitsa koyenera, kuonetsetsa kuti tepiyo imakhala yosalala komanso yosalala kuti mupange chisindikizo changwiro.

Kusiyana kumeneku pakati pa tepi ndi phala ndikofunika kwambiri pazitsulo zapulasitiki. Ambiri wambamabomba a pipeali ndi mankhwala opangidwa ndi petroleum omwe amatha kuwononga PVC ndi mankhwala, ndikupangitsa kuti ikhale yolimba komanso yokhoza kusweka ngati ikugwira ntchito bwino.Teflon tepi, kumbali ina, imakhala yopanda pake. Zimagwira ntchito ngati zosindikizira komanso zopangira mafuta, zomwe zimadzaza timipata tating'onoting'ono ta ulusi popanda kupangitsa kuti pakhale mphamvu yowopsa yakunja yomwe phala lingathe. Izi zimalepheretsa kupsinjika kwa mkazi.

Mukamakulunga ulusi, nthawi zonse muzipita molunjika pamene mukuyang'ana kumapeto kwake. Izi zimatsimikizira kuti mukamangitsa valavu, tepiyo imakhala yosalala m'malo momangirira ndi kumasulidwa.

Momwe mungayikitsire valavu ya mpira pa chitoliro cha PVC?

Muli ndi valavu ya mpira koma chitoliro chanu ndi chosalala. Muyenera kuwalumikiza, koma mukudziwa kuti simungathe kumata ulusi kapena ulusi wosalala. Chokwanira bwino ndi chiyani?

Kuti mulumikize valavu ya mpira ku chitoliro chosalala cha PVC, muyenera choyamba chosungunulira chosungunulira (kumata) adaputala yamphongo ya PVC pa chitoliro. Simenti ikachira, mutha kukhazikitsa valavu ya ulusi pa adaputala.

Simungathe kupanga ulusi pachitoliro chokhazikika, chosalala cha PVC; khomalo ndi lochepa kwambiri ndipo likhoza kulephera nthawi yomweyo. Kulumikizana kuyenera kupangidwa ndi ma adapter oyenera. Kwa ntchito iyi, muyenera aPVC Male Adapter(nthawi zambiri amatchedwa adapter ya MPT kapena MIPT). Mbali imodzi ili ndi zitsulo zosalala, ndipo mbali inayo ili ndi ulusi wamphongo. Mumagwiritsa ntchito pulayimale ya PVC yoyambira ndi simenti kuti muwotchere kumapeto kwa socket pa chitoliro chanu, ndikupanga chidutswa chimodzi, chosakanikirana. Chinsinsi apa ndi kuleza mtima. Inu muyenera kuzilola izomankhwala osungunulira-weldkwathunthu musanagwiritse ntchito torque iliyonse ku ulusi. Kugwiritsa ntchito mphamvu molawirira kwambiri kumatha kusokoneza mgwirizano watsopano wamankhwala, kupangitsa kuti malo olumikizidwawo atayike. Nthawi zonse ndimalangiza makasitomala a Budi kuti adikire kwa maola 24 kuti akhale otetezeka.

Momwe mungayikitsire valavu ya ulusi?

Munamangitsa valavu yanu yatsopano ya ulusi mpaka inamveka yolimba, koma kumva kung'ung'udza kowawa. Tsopano valavu yawonongeka, ndipo muyenera kuidula ndikuyambanso.

Njira yoyenera yomangirira ndi "yolimba m'manja kuphatikiza kutembenuka kumodzi kapena kuwiri." Ingopukutani valavuyo ndi dzanja mpaka itakhazikika, kenaka gwiritsani ntchito wrench kuti mutembenuke kamodzi kapena kawiri komaliza. Imani pamenepo.

Kumangitsa kwambiri ndiye chifukwa choyamba chakulephera kwa zopangira pulasitiki. Mosiyana ndi zitsulo, zomwe zimatha kutambasula ndi kupunduka, PVC ndi yolimba. Mukagwetsera pansi pa valavu ya PVC, mumayika mphamvu yakunja pazipupa zachikazi, kuyesera kuti mutsegule. The “zolimba m'manja kuphatikiza mokhota imodzi kapena ziwiri"Kulimbitsa dzanja kokha kumapangitsa kuti ulusiwo ugwirizane bwino." Kutembenuka komaliza kapena kuwiri ndi wrench kumangokwanira kukakamiza zigawo za tepi ya Teflon, kupanga chisindikizo changwiro, chopanda madzi popanda kuika kupsinjika koopsa pa pulasitiki. zaka.

Momwe mungalumikizire valavu yotseka ku PVC?

Muyenera kuwonjezera chotseka pamzere womwe ulipo wa PVC. Simukutsimikiza ngati muyenera kugwiritsa ntchito valavu yokhala ndi ulusi kapena valavu yomatira kuti mugwiritse ntchito.

Powonjezera chotseka pamzere womwe ulipo wa PVC, valavu yowona ya mpira ndiye njira yabwino kwambiri. Zimalola kukonza mtsogolo. Gwiritsani ntchito mtundu wa solvent-weld (socket) pamakina enieni a PVC, kapena mtundu wa ulusi ngati mukulumikiza pafupi ndi zitsulo.

Pamene mukufunika kudula mzere kuti muwonjezere kutseka, kuganizira zamtsogolo ndikofunikira. Valavu yowona ya mpira ndiye chisankho chapamwamba apa. Mutha kudula chitoliro, kumata malekezero awiri a mgwirizano, kenaka yikani thupi la valve pakati pawo. Izi ndizabwino kwambiri kuposa valavu yokhazikika chifukwa mutha kungochotsa mtedza wa valavu kuti muchotse valavu yonse kuti muyeretse kapena kuyisintha popanda kudulanso chitoliro. Ngati makina anu ndi 100% PVC, chosungunulira-weld (socket) valavu yeniyeni ya mgwirizano ndi yangwiro. Ngati mukuwonjezera kutseka pafupi ndi mpope kapena fyuluta ndi ulusi wachitsulo, ndiye kuti ulusivalavu ya mgwirizano weniwenindiyo njira yopita. Mutha kumata adaputala ya ulusi pachitoliro cha PVC kaye, kenako ndikuyika valavu. Kusinthasintha uku ndichifukwa chake ife ku Pntek timagogomezera kwambiri mgwirizano weniweni.
