Mwapanga kale, koma chisindikizo chotuluka madzi chimatanthauza kuwononga nthawi, ndalama, ndi zipangizo. Cholumikizira chimodzi choipa pa mzere wa PVC chingakukakamizeni kudula gawo lonse ndikuyambanso.

Kuti muyike valavu ya mpira pa chitoliro cha PVC, mumagwiritsa ntchito welding ya solvent. Izi zimaphatikizapo kudula chitolirocho bwino, kuchotsa matuza, kugwiritsa ntchito pulasitala wa PVC ndi simenti pamalo onse awiri, kenako kuzikankhira pamodzi ndi kupotoza kotala ndikuzigwira mwamphamvu mpaka chigwirizano cha mankhwala chitakhala.

Izi sizimangophatikiza pulasitiki yokha; ndi njira ya mankhwala yomwe imagwirizanitsa pulasitiki kukhala chinthu chimodzi cholimba. Kuchita bwino sikungakambirane kwa akatswiri. Ndi mfundo yomwe ndimayigogomezera nthawi zonse ndi ogwirizana nawo monga Budi ku Indonesia. Makasitomala ake, kaya ndi makontrakitala akuluakulu kapena ogulitsa am'deralo, amadalira kudalirika. Kulephera kwa mgwirizano sikungotulutsa madzi; ndi kuchedwa kwa polojekiti komanso kuwononga mbiri yawo. Tiyeni tikambirane mafunso ofunikira kuti kukhazikitsa kulikonse kukhale kopambana.

Kodi mumalumikiza bwanji valavu ku chitoliro cha PVC?

Muli ndi valavu m'manja, koma mukuyang'ana chitoliro chosalala. Mukudziwa kuti pali mitundu yosiyanasiyana yolumikizira, koma ndi iti yoyenera ntchito yanu kuti ikutsimikizireni kuti dongosolo lanu ndi lolimba komanso lopanda madzi?

Mumalumikiza valavu ku chitoliro cha PVC m'njira ziwiri: kulumikizana kosatha kwa solvent-weld (socket), komwe kuli bwino kwambiri pa PVC-to-PVC, kapena kulumikizana kogwiritsidwa ntchito bwino kwa ulusi, komwe kuli koyenera kulumikiza PVC ku zitsulo monga mapampu.

Kusankha njira yoyenera ndi sitepe yoyamba yokhazikitsa akatswiri. Kwa makina omwe ali ndi PVC yokha,kuwotcherera zosungunulirandiye muyezo wamakampani. Imapanga cholumikizira chosasunthika, cholumikizidwa chomwe chili cholimba ngati chitolirocho. Njirayi ndi yachangu, yodalirika, komanso yokhazikika. Malumikizidwe olumikizidwa amagwiritsidwa ntchito mukafuna kulumikiza chingwe chanu cha PVC ku china chake ndi ulusi wachitsulo womwe ulipo, kapena mukayembekezera kuchotsa valavu mosavuta pambuyo pake. Komabe, zolumikizira zapulasitiki zolumikizidwa ziyenera kuyikidwa mosamala kuti ming'alu isamangidwe kwambiri. Pa mapaipi ambiri a PVC wamba, nthawi zonse ndimalimbikitsa mphamvu ndi kuphweka kwa kulumikizana kwa solvent-weld. Ngati kukonza bwino ndikofunikira, avalavu yolimba ya mpira wa mgwirizano weniweniimakupatsani zabwino kwambiri padziko lonse lapansi.

Kodi njira yoyenera yokhazikitsira valavu ya mpira ndi iti?

Vavulovuyo yamatidwa bwino kwambiri, koma tsopano chogwiriracho chagunda khoma ndipo sichingathe kutseka. Kapena mwayika valavu yeniyeni yogwirizana nayo mwamphamvu kwambiri pa chigongono kotero kuti simungathe kuigwira ndi wrench.

"Njira yoyenera" yokhazikitsira valavu ya mpira ndikukonzekera momwe ingagwiritsidwire ntchito. Izi zikutanthauza kuti choyamba muyike chogwiriracho kuti muwonetsetse kuti chili ndi malo ozungulira madigiri 90 komanso kuti ma union nuts azitha kugwiritsidwa ntchito mtsogolo.

Kukhazikitsa bwino kumapitirira kungokhalachisindikizo chosatulutsa madzi; ndi za magwiridwe antchito a nthawi yayitali. Apa ndi pomwe mphindi imodzi yokonzekera imasunga ola limodzi lokonzanso. Musanatsegule primer, ikani valavu pamalo ake ndikugwedeza chogwirira. Kodi imayenda momasuka kuchokera potseguka kwathunthu kupita potseka kwathunthu? Ngati sichoncho, muyenera kusintha momwe imayendera. Kachiwiri, ngati mukugwiritsa ntchito chipangizo chapamwamba kwambirivalavu yeniyeni yogwirizanaMonga athu ku Pntek, muyenera kuonetsetsa kuti mwakwanitsa kupeza ma union nuts. Cholinga cha ma valve awa ndikulola kuti thupi la valve lichotsedwe popanda kudula chitoliro. Nthawi zonse ndimakumbutsa Budi kuti auze makasitomala ake izi: ngati simungathe kuyika wrench pa ma nats, mwalephera cholinga chonse cha valavu. Ganizirani ngati kukhazikitsa osati lero lokha, komanso kwa munthu amene ayenera kuikonza zaka zisanu kuchokera pano.

Kodi ma valve a mpira wa PVC ndi olunjika?

Mwakonzeka ndi simenti, koma mukuima kaye, mukuyang'ana muvi woyenda pa valavu. Mukudziwa kuti kumata valavu yolunjika kumbuyo kungakhale kulakwitsa kwakukulu komanso kokwera mtengo.

Ayi, valavu yodziwika bwino ya mpira wa PVC siili yolunjika mbali zonse ziwiri; ndi yolunjika mbali zonse ziwiri. Imagwiritsa ntchito kapangidwe kofanana ndi zotsekera mbali zonse ziwiri, zomwe zimathandiza kuti izitseke kuyenda mofanana kuchokera mbali zonse ziwiri. "Njira" yokhayo yodetsa nkhawa ndi momwe imayendera thupi kuti ipeze chogwirira.

Funso ili ndi labwino kwambiri komanso lofala. Chenjezo lanu ndi loyenera chifukwa ma valve ena, mongama valve owunikirakapena ma valve ozungulira, ndi olunjika bwino ndipo adzalephera ngati atayikidwa kumbuyo. Ali ndi muvi woonekera bwino pa thupi kuti ukutsogolereni.valavu ya mpiraKomabe, imagwira ntchito mosiyana. Pakati pake ndi mpira wosavuta wokhala ndi dzenje kudzera, womwe umazungulira kuti utseke pampando. Popeza pali mpando kumbali zonse ziwiri zakumtunda ndi zakumunsi kwa mpirawo, umapanga chisindikizo cholimba mosasamala kanthu kuti mphamvu ikuchokera kuti. Chifukwa chake, mutha kupumula. Simungathe kuyika valavu ya mpira wamba "kumbuyo" pankhani ya kuyenda. Kapangidwe kosavuta komanso kolimba aka ndi chifukwa chimodzi chomwe amatchuka kwambiri. Ingoyang'anani pakuyiyika kuti chogwirira ndi mayunitsi zikhale zosavuta kuzifikira.

Kodi ma valve a mpira wa PVC ndi odalirika bwanji?

Mwaona valavu yotsika mtengo, yopanda dzina la PVC ikung'ambika kapena kutuluka madzi patatha chaka chimodzi chokha, zomwe zimakupangitsani kukayikira za chinthucho. Mukudabwa ngati muyenera kungogwiritsa ntchito valavu yachitsulo yokwera mtengo.

Ma valve apamwamba a PVC ndi odalirika kwambiri ndipo amatha kukhalapo kwa zaka zambiri. Moyo wawo umadalira mtundu wa zinthu zopangira (virgin vs. PVC yobwezeretsedwanso), kulondola kwa kupanga, ndi kuyika bwino. Valavu yabwino nthawi zambiri imakhala yolimba kuposa makina omwe ili.

Kudalirika kwaValavu ya mpira wa PVCZimatengera zomwe zapangidwa ndi momwe zapangidwira. Ili ndiye maziko a nzeru zathu ku Pntek.

Kodi N’chiyani Chimatsimikiza Kudalirika?

• Ubwino wa Zinthu:Timalimbikira kugwiritsa ntchitoPVC yopangidwa ndi 100% yopanda chivindikiroMa valve ambiri otsika mtengo amagwiritsa ntchito zinthu zobwezerezedwanso kapena zodzaza, zomwe zimapangitsa kuti pulasitiki ikhale yofooka komanso yolephera kugwira ntchito ikapanikizika kapena ikakhudzidwa ndi UV. Virgin PVC imapereka mphamvu zambiri komanso kukana mankhwala.
• Kupanga Molondola:Kupanga kwathu kodzipangira kumatsimikizira kuti valavu iliyonse ndi yofanana. Mpirawo uyenera kukhala wozungulira bwino komanso mipando yake ikhale yosalala bwino kuti ipange chisindikizo cholimba ngati thovu. Timayesa mavalavu athu kuti akhale apamwamba kwambiri kuposa momwe angawonere m'munda.
• Kapangidwe ka Utali Wautali:Zinthu monga thupi lenileni la mgwirizano, mphete za EPDM kapena FKM O, ndi kapangidwe ka tsinde kolimba zonse zimathandiza kuti ntchito ikhale yayitali. Uku ndiko kusiyana pakati pa gawo lotayidwa ndi chuma cha nthawi yayitali.

Valavu ya PVC yopangidwa bwino komanso yoyikidwa bwino si yofooka; ndi njira yolimba, yolimba, komanso yotsika mtengo.
