Munamatira valavu yanu yatsopano ya PVC mu payipi, koma tsopano yatuluka madzi. Cholumikizira chimodzi choyipa chimatanthauza kuti muyenera kudula payipiyo ndikuyambanso, ndikuwononga nthawi ndi ndalama.

Kuyika bwinoValavu ya mpira wa PVC, muyenera kugwiritsa ntchito pulasitala yeniyeni ya PVC ndisimenti yosungunuliraNjirayi imaphatikizapo kudula chitolirocho, kuchotsa chitolirocho m'madzi, kupukuta pamwamba pa zonse ziwiri, kugwiritsa ntchito simenti, kenako kukankhira ndi kugwira cholumikiziracho mwamphamvu kwa masekondi 30 kuti apange cholumikizira cha mankhwala chokhazikika.

Njirayi ikunena za kupanga mgwirizano wa mankhwala womwe uli wolimba ngati chitolirocho, osati kungolumikiza ziwalo pamodzi. Ndi nkhani yofunika kwambiri yomwe nthawi zonse ndimagogomezera ndi anzanga, monga Budi, woyang'anira zogula ku Indonesia. Makasitomala ake, kuyambira makontrakitala akuluakulu mpaka ogulitsa am'deralo, sangakwanitse kulephera. Kugwirizana kokha kolakwika kumatha kuwononga nthawi ndi bajeti ya polojekiti. Tiyeni tikambirane mafunso ofunikira kuti tiwonetsetse kuti kukhazikitsa kulikonse komwe mukugwira ndi kopambana kwanthawi yayitali.

Kodi mumayika bwanji valavu ya mpira pa chitoliro cha PVC?

Muli ndi zigawo zoyenera, koma mukudziwa kuti palibe mwayi wina ndi simenti ya PVC. Cholakwika chimodzi chaching'ono chimatanthauza kudula gawo la chitoliro ndikuyambanso kuyambira pachiyambi.

Njira yokhazikitsa imagwiritsa ntchito kuwotcherera kwa solvent ndipo imaphatikizapo magawo asanu ofunikira: kudula chitoliro cha sikweya, kuchotsa m'mphepete, kugwiritsa ntchito pulasitala wa PVC pamalo onse awiri, kupaka ndi simenti ya PVC, kenako kukankhira ziwalozo pamodzi ndi kutembenuza kotala ndikuzigwira mwamphamvu.

Kuchita bwino kwa njirayi ndiko kumasiyanitsa ntchito yaukadaulo ndi vuto lamtsogolo. Tiyeni tifotokoze mwatsatanetsatane gawo lililonse. Iyi ndi njira yeniyeni yomwe ndimapereka kwa makasitomala a Budi kuti nditsimikizire chisindikizo chabwino.

1. Dulani & Chotsani Zolakwika:Yambani ndi kudula chitoliro chanu choyera, cha sikweya. Ngodya iliyonse ingapangitse mpata pa cholumikizira. Mukadula, gwiritsani ntchito chida chochotsera ming'alu kapena mpeni wosavuta kuti mumete fuzz iliyonse yapulasitiki kuchokera mkati ndi kunja kwa m'mphepete mwa chitoliro. Ma burrs awa amatha kukanda simenti ndikuletsa chitoliro kuti chisakhale ndi malo okwanira.
2. Choyamba:Valani chovala chaulere chaChoyambira cha PVC(nthawi zambiri imakhala yofiirira) kunja kwa chitoliro ndi mkati mwa soketi ya valavu. Musadumphe sitepe iyi! Primer si yoyeretsa yokha; imayamba kufewetsa pulasitiki, ndikuikonzekera kuti igwiritsidwe ntchito ndi mankhwala.
3. Simenti:Pamene primer ikadali yonyowa, ikani gawo lofanana laSimenti ya PVCPakani pa malo okonzedwa kale. Choyamba ikani pa chitoliro, kenako patsani soketi ya valavu ulusi woonda.
4. Kankhani, Tembenuzani & Gwirani:Kankhirani chitolirocho nthawi yomweyo mu soketi ndi kupotoza pang'ono kotala. Kupotoza kumeneku kumathandiza kufalitsa simenti mofanana. Kenako muyenera kugwira cholumikiziracho mwamphamvu kwa masekondi osachepera 30. Kuchitapo kanthu kwa mankhwala kumabweretsa kupanikizika komwe kudzayesa kukankhira chitolirocho kunja.

Kodi njira yoyenera yokhazikitsira valavu ya mpira ndi iti?

Vavu ili mkati, koma chogwiriracho chagunda khoma. Kapena choipa kwambiri, mwayika valavu yeniyeni yogwirizana pafupi kwambiri ndi cholumikizira china kotero kuti simungathe kuyika chivundikiro pa nati.

"Njira yoyenera" yokhazikitsira valavu ya mpira imaganizira momwe ingagwiritsidwire ntchito mtsogolo. Izi zikutanthauza kuonetsetsa kuti chogwiriracho chili ndi malo okwanira ozungulira madigiri 90 komanso kuti ma union nati pa valavu yeniyeni ya union akupezeka mosavuta kuti akakonzedwe mtsogolo.

Kukhazikitsa bwino sikutanthauza kungokhalachisindikizo chosatulutsa madzi; ndi za magwiridwe antchito a nthawi yayitali. Apa ndi pomwe kukonzekera pang'ono kumapanga kusiyana kwakukulu. Cholakwika chomwe ndimachiwona kwambiri ndikusowa kukonzekera kolowera. Valavu ya mpira iyenera kuzungulira madigiri 90 kuti ipite kuchokera pakutseguka kwathunthu mpaka kutsekedwa kwathunthu. Musanatsegule chidebe cha simenti, gwirani valavu pamalo pake ndikugwedeza chogwirira chake chonse. Onetsetsani kuti sichikugunda khoma, chitoliro china, kapena china chilichonse. Mfundo yachiwiri, makamaka ya Pntek yathuma valve enieni a mgwirizano, ndi mwayi wopeza mgwirizano wa ogwira ntchito. Phindu lonse la kapangidwe ka mgwirizano weniweni ndilakuti mutha kumasula ma union ndikutulutsa thupi lalikulu kuti likonzedwe kapena kusinthidwa popanda kudula chitoliro. Nthawi zonse ndimakumbutsa Budi kuti agogomeze izi kwa makasitomala ake a kontrakitala. Ngati muyika valavu pomwe simungathe kuyika chitoliro pamakina amenewo, mwangosintha valavu yapamwamba, yogwiritsidwa ntchito kukhala yokhazikika, yotayidwa.

Kodi mumalumikiza bwanji valavu ku chitoliro cha PVC?

Valavu yanu ili ndi ulusi, koma chitoliro chanu ndi chosalala. Mukudabwa ngati muyenera kuchimata, kuchilumikiza, kapena ngati njira imodzi ndi yabwino kuposa inayo kuti mulumikizane bwino.

Pali njira ziwiri zazikulu: kuwotcherera zosungunulira (gluing) kuti pakhale chomangira chokhazikika, chosakanikirana, ndi zolumikizira za ulusi za cholumikizira chomwe chingachotsedwe. Pa makina a PVC-to-PVC, kuwotcherera zosungunulira ndiyo njira yamphamvu komanso yodziwika bwino.

Kusankha mtundu woyenera wolumikizira ndikofunikira kwambiri. Makina ambiri a PVC amadalirakuwotcherera zosungunulira, ndipo pachifukwa chabwino. Sizimangolumikiza ziwalozo pamodzi; zimaziphatikiza ndi mankhwala kukhala pulasitiki imodzi yopanda msoko yomwe ndi yamphamvu kwambiri komanso yosatulutsa madzi. Zolumikizira zokhala ndi ulusi zimakhala ndi malo ake, komanso zimakhala ndi zofooka. Ndi zothandiza polumikiza valavu ya PVC ku pampu yachitsulo kapena thanki yomwe ili ndi ulusi kale. Komabe, zolumikizira zapulasitiki zokhala ndi ulusi zimatha kukhala gwero la kutuluka madzi ngati sizimangiriridwa bwino ndi tepi ya Teflon kapena phala. Chofunika kwambiri, kumangitsa kwambiri cholumikizira cha pulasitiki chokhala ndi ulusi ndi cholakwika chofala chomwe chingaswe cholumikizira chachikazi, zomwe zimapangitsa kuti chilephereke.

Kuyerekeza Njira Yolumikizira

Kodi ma valve a mpira wa PVC ndi olunjika?

Simenti yakonzeka, koma mukukayikira, kufunafuna muvi pa valavu. Kumata valavu yolozera kumbuyo kungakhale kulakwitsa kwakukulu, kukukakamizani kuiwononga.

Ayi, valavu yodziwika bwino ya mpira wa PVC imazungulira mbali zonse ziwiri ndipo imatseka kuyenda kwa madzi mofanana kuchokera mbali zonse ziwiri. Ntchito yake siidalira momwe madzi akuyendera. "Malo" okhawo ofunika ndikuyiyika kuti muzitha kugwiritsa ntchito chogwirira ndi union nuts.

Funso ili ndi labwino kwambiri lomwe limasonyeza kuganiza mosamala. Muli ndi ufulu kukhala osamala, chifukwa ma valve ena ndi olunjika.valavu yoyezeraMwachitsanzo, imalola kuyenda mbali imodzi yokha ndipo idzakhala ndi muvi wowonekera bwino wosindikizidwa pamenepo. Ngati itayikidwa kumbuyo, sigwira ntchito. Komabe, ama valavu a mpiraKapangidwe kake ndi kofanana. Ili ndi mpira wokhala ndi dzenje lomwe limatseka mpando. Popeza pali mpando mbali zonse ziwiri zakumtunda ndi zakumunsi, valavu imatseka bwino mosasamala kanthu kuti madzi akuyenda bwanji. Chifukwa chake, simungathe kuyiyika "kumbuyo" pankhani ya kayendedwe ka madzi. Monga ndanenera kale, "njira" yokhayo yomwe muyenera kuda nkhawa nayo ndi momwe mungagwiritsire ntchito valavu. Kodi mutha kutembenuza chogwirira? Kodi mutha kulowa mu unions? Imeneyo ndiye mayeso enieni a kukhazikitsa koyenera kwa valavu yabwino ngati yomwe timapanga ku Pntek.

Mapeto

Kuti muyike bwino valavu ya mpira wa PVC, gwiritsani ntchito pulasitala ndi simenti yoyenera. Konzani njira yolumikizira chogwirira ndi union nut kuti muwonetsetse kuti pali kulumikizana kodalirika, kosataya madzi, komanso koyenera.
