Mwayika mosamala valavu yatsopano ya PVC yolumikizidwa, koma ikutuluka pang'onopang'ono kuchokera mu ulusiwo. Kuilimbitsa kumamveka koopsa, chifukwa mukudziwa kuti kupotoza kamodzi kokha kungaswe cholumikiziracho.

Kuti muyike bwino valavu ya mpira wa PVC yolumikizidwa, kulungani ulusi wa amuna ndi tepi ya Teflon ya zigawo 3-4. Nthawi zonse kulungani molunjika ku mbali yomangirira. Kenako, ikanikeni mwamphamvu m'manja, ndipo gwiritsani ntchito wrench kwa mphindi imodzi kapena ziwiri zokha zomaliza.

Ulusi wotuluka ndi chimodzi mwa zinthu zomwe zimavuta kwambiri kukhazikitsa. Nthawi zambiri zimachitika chifukwa cha cholakwika chaching'ono chomwe chingapeweke pokonzekera kapena kulimbitsa. Nthawi zambiri ndimakambirana izi ndi mnzanga ku Indonesia, Budi, chifukwa nthawi zonse makasitomala ake amakumana ndi vuto. Kulumikizana kotetezeka komanso kopanda kutuluka kwa ulusi ndikosavuta. Mukungofunika kutsatira njira zosavuta koma zofunika kwambiri. Tiyeni tikambirane mafunso ofunikira kuti tikonze nthawi iliyonse.

Kodi mungayikitse bwanji zida zolumikizira mapaipi a PVC?

Munagwiritsa ntchito phala lotsekera ulusi lomwe limagwira ntchito bwino pa chitsulo, koma PVC yanu ikadali kutuluka. Choyipa kwambiri, mukuopa kuti mankhwala omwe ali mu phalalo angawononge pulasitiki pakapita nthawi.

Pa PVC yopangidwa ndi ulusi, nthawi zonse gwiritsani ntchito tepi ya Teflon m'malo mwa chitoliro kapena phala. Mangani ulusi wamphongo katatu kapena kanayi mbali yomweyo mudzalimbitsa cholumikizira, kuonetsetsa kuti tepiyo yakhazikika bwino komanso yosalala kuti ipange chisindikizo chabwino.

Kusiyana kumeneku pakati pa tepi ndi phala ndikofunikira kwambiri pa zomangira za pulasitiki.mapaipi opangidwa ndi dopeMuli mankhwala ochokera ku mafuta omwe amatha kuukira PVC mwa mankhwala, zomwe zimapangitsa kuti ikhale yofooka komanso yosweka chifukwa cha kuthamanga kwabwinobwino kwa ntchito.Tepi ya TeflonKumbali ina, ndi yopanda mphamvu. Imagwira ntchito ngati chotseka komanso chopaka mafuta, kudzaza mipata yaying'ono mu ulusi popanda kupanga mphamvu yoopsa yakunja yomwe phala lingathe. Izi zimaletsa kupsinjika pa kukwanira kwa akazi.

Kusankha kwa Sealant pa Ulusi wa PVC

Mukakulunga ulusi, nthawi zonse muziyenda molunjika pamene mukuyang'ana kumapeto kwa cholumikizira. Izi zimatsimikizira kuti pamene mukulimbitsa valavu, tepiyo imakhala yosalala m'malo moikulunga ndi kuimasula.

Kodi mungayikitse bwanji valavu ya mpira pa chitoliro cha PVC?

Muli ndi valavu yolumikizidwa koma chitoliro chanu ndi chosalala. Muyenera kuwalumikiza, koma mukudziwa kuti simungathe kumata ulusi kapena kulumikiza chitoliro chosalala. Kodi cholumikizira choyenera ndi chiyani?

Kuti mulumikize valavu yolumikizidwa ndi chitoliro chosalala cha PVC, choyamba muyenera kulumikiza adapter ya PVC ya amuna yolumikizidwa ndi solvent (glue) pa chitolirocho. Simenti ikatha bwino, mutha kuyika valavu yolumikizidwa pa adaputala.

Simungathe kupanga ulusi pa chitoliro chokhazikika komanso chosalala cha PVC; khoma ndi lochepa kwambiri ndipo lingalephereke nthawi yomweyo. Kulumikizana kuyenera kupangidwa ndi cholumikizira choyenera cha adaputala. Pa ntchitoyi, mufunika chida cholumikiziraAdaputala ya Amuna a PVC(nthawi zambiri imatchedwa adaputala ya MPT kapena MIPT). Mbali imodzi ili ndi soketi yosalala, ndipo inayo ili ndi ulusi wamphongo woumba. Mumagwiritsa ntchito njira yokhazikika ya PVC primer ndi simenti kuti mulumikize mapeto a soketiyo pa chitoliro chanu, ndikupanga chidutswa chimodzi, chosakanikirana. Chofunika apa ndi kuleza mtima. Muyenera kulola zimenezo.mankhwala osungunula ndi kusungunulaKuyika mphamvu molawirira kwambiri kungathe kuswa mgwirizano watsopano wa mankhwala, zomwe zimapangitsa kuti pakhale kutuluka kwa madzi pamalo olumikizirana ndi guluu. Nthawi zonse ndimalangiza makasitomala a Budi kuti adikire maola osachepera 24 kuti akhale otetezeka.

Kodi mungayike bwanji valavu yolumikizidwa?

Munalimbitsa valavu yanu yatsopano yolumikizidwa mpaka itamveka ngati yolimba, kenako munamva ming'alu yonyansa. Tsopano valavu yawonongeka, ndipo muyenera kuyidula ndikuyambanso.

Njira yolondola yomangira ndi "kumanga ndi dzanja kuphatikiza kutembenuza kamodzi kapena kawiri." Ingokanikizani valavu ndi dzanja mpaka itakhazikika, kenako gwiritsani ntchito wrench kuti muyitembenuze kamodzi kapena kawiri komaliza. Imani pamenepo.

Kumangika kwambiri ndiye chifukwa chachikulu chomwe chimalepheretsa zolumikizira za pulasitiki zokhala ndi ulusi. Mosiyana ndi chitsulo, chomwe chimatha kutambasuka ndikuwonongeka, PVC ndi yolimba. Mukagunda valavu ya PVC yokhala ndi ulusi, mumakhala mukuyika mphamvu yayikulu pakhoma la cholumikizira chachikazi, ndikuyesera kuchigawa.kugwirana ndi dzanja kuphatikiza kutembenukira kamodzi kapena kawiri"Lamulo ndi muyezo wagolide pazifukwa zina. Kumanga ndi dzanja kokha kumapangitsa kuti ulusi ugwirizane bwino. Kutembenuza kamodzi kapena kawiri komaliza ndi wrench ndikokwanira kukanikiza zigawo za tepi ya Teflon, ndikupanga chisindikizo chabwino kwambiri, chopanda madzi popanda kuyika mphamvu yoopsa pa pulasitiki. Nthawi zonse ndimauza anzanga kuti "cholimba" sichili bwino ndi PVC. Kugwirizana kolimba komanso kolimba kumapanga chisindikizo chokhazikika, chosatulutsa madzi chomwe chidzakhalapo kwa zaka zambiri.

Kodi mungalumikize bwanji valavu yotseka ku PVC?

Muyenera kuwonjezera chozimitsa pa mzere wa PVC womwe ulipo kale. Simukudziwa ngati muyenera kugwiritsa ntchito valavu yolumikizidwa kapena valavu yokhazikika yomatidwa pa ntchitoyi.

Pofuna kuwonjezera chozimitsa pa mzere wa PVC womwe ulipo kale, valavu yeniyeni ya mpira wa union ndiyo njira yabwino kwambiri. Imalola kukonza mtsogolo. Gwiritsani ntchito mtundu wa solvent-weld (socket) pamakina enieni a PVC, kapena mtundu wa ulusi ngati ukugwirizana ndi zigawo zachitsulo.

Mukafunika kudula mzere kuti muwonjezere kutseka, kuganizira za tsogolo ndikofunikira. Valavu yeniyeni ya union ndiye chisankho chabwino kwambiri apa. Mutha kudula chitoliro, kumata malekezero awiri a union, kenako kuyika thupi la valavu pakati pawo. Izi ndizabwino kwambiri kuposa valavu yokhazikika chifukwa mutha kungotsegula mtedza wa union kuti muchotse thupi lonse la valavu kuti muyeretse kapena kusintha popanda kudulanso chitolirocho. Ngati makina anu ndi 100% PVC, valavu yeniyeni ya union yosungunula (socket) ndi yangwiro. Ngati mukuwonjezera kutseka pafupi ndi pampu kapena fyuluta yokhala ndi ulusi wachitsulo, ndiye kuti ulusiwo ndi wopangidwa ndi ulusi.valavu yeniyeni yogwirizanaNjira ndiyo yoyenera. Choyamba mungamamatire adaputala yolumikizidwa ndi ulusi pa chitoliro cha PVC, kenako muyike valavu. Kusinthasintha kumeneku ndi chifukwa chake ife ku Pntek timagogomezera kwambiri kapangidwe ka union yeniyeni.
