Muli ndi valavu yoyenera ndi chitoliro, koma cholakwika chimodzi chaching'ono pakuyika chingayambitse kutayikira kosatha. Izi zimakukakamizani kudula chilichonse ndikuyambanso, kuwononga nthawi ndi ndalama.

Kuti muyike valavu ya mpira pa chitoliro cha PVC, choyamba muyenera kusankha mtundu woyenera wolumikizira: kaya valavu ya ulusi pogwiritsa ntchito tepi ya PTFE kapena socket valve pogwiritsa ntchito PVC primer ndi simenti. Kukonzekera koyenera ndi njira ndizofunikira kuti chisindikizo chisadutse.

Kupambana kwa ntchito iliyonse yopangira mapaipi kumatsikira pamalumikizidwe. Kupeza izi ndi zomwe ndimakambirana nthawi zambiri ndi abwenzi ngati Budi ku Indonesia, chifukwa makasitomala ake amakumana ndi izi tsiku lililonse. Vavu yotuluka imakhala pafupifupi konse chifukwa valavu palokha ndi yoyipa; ndi chifukwa cholumikizira sichinapangidwe bwino. Nkhani yabwino ndiyakuti kupanga chisindikizo changwiro, chokhazikika ndikosavuta ngati mungotsatira njira zingapo zosavuta. Chosankha chofunikira kwambiri chomwe mungapange ndikusankha kugwiritsa ntchito ulusi kapena guluu.

Momwe mungalumikizire valavu ya mpira ku PVC?

Mukuwona ma valve opangidwa ndi socket alipo. Kusankha yolakwika kumatanthauza kuti ziwalo zanu sizingagwirizane, kuyimitsa polojekiti yanu mpaka mutapeza valavu yoyenera.

Mumalumikiza valavu ya mpira ku PVC m'njira ziwiri. Mumagwiritsa ntchito maulumikizidwe a ulusi (NPT kapena BSP) pamakina omwe angafunikire kupasuka, kapena ma socket (solvent weld) olumikizana okhazikika, omata.

Chinthu choyamba nthawi zonse ndikufananiza valavu yanu ndi dongosolo lanu la chitoliro. Ngati mapaipi anu a PVC ali kale ndi ulusi wachimuna, muyenera valavu yachikazi. Koma pa ntchito zambiri zatsopano zapaipi, makamaka za ulimi wothirira kapena maiwe, mudzagwiritsa ntchito mavavu a socket ndi simenti yosungunulira. Nthawi zonse ndimawona kuti ndizothandiza pamene gulu la Budi likuwonetsa makasitomala tebulo kuti amveketse chisankho. Njirayi imayendetsedwa ndi valve yomwe muli nayo. Simungathe kumata valavu yokhala ndi ulusi kapena kulumikiza valavu ya socket. Njira yodziwika bwino komanso yokhazikika yolumikizira PVC-to-PVC ndisoketi, kapenazosungunulira weld, njira. Izi sizimangomamatira mbalizo; imasakaniza valavu ndi chitoliro kukhala pulasitiki imodzi, yopanda msoko, yomwe imakhala yamphamvu kwambiri komanso yodalirika ikachitidwa molondola.

Kuwonongeka kwa Njira Yogwirizanitsa

Kodi pali njira yolondola yoyika valavu ya mpira?

Mukuganiza kuti valve imagwira ntchito mofanana kumbali iliyonse. Koma kuyiyika molakwika kumatha kuletsa kuyenda, kupanga phokoso, kapena kupangitsa kuti zisatheke kugwira ntchito pambuyo pake.

Inde, pali njira yolondola. Valavu iyenera kuyikidwa ndi chogwirira chofikira, mtedza wa mgwirizano (pa valve yeniyeni ya mgwirizano) yoyikidwa kuti ichotsedwe mosavuta, ndipo nthawi zonse imakhala yotseguka panthawi ya gluing.

Zing'onozing'ono zingapo zimalekanitsa unsembe wa akatswiri kuchokera kwa amateur. Choyamba,kusamalira orientation. Musanayambe kumata chilichonse, ikani valavu ndikuonetsetsa kuti chogwiriracho chili ndi chilolezo chokwanira kuti chitembenukire madigiri 90. Ndawonapo ma valve atayikidwa pafupi ndi khoma kotero kuti chogwiriracho chimangotsegula pakati. Zikumveka zosavuta, koma ndi kulakwitsa wamba. Chachiwiri, pa ma valve athu a True Union, timaphatikizapo mtedza wa mgwirizano. Izi zidapangidwa kuti muzitha kuzimasula ndikukweza ma valve kuchokera papaipi kuti mugwiritse ntchito. Muyenera kukhazikitsa valavu yokhala ndi malo okwanira kuti mumasulire mtedzawu. Chofunikira kwambiri, komabe, ndi momwe ma valve alili panthawi yoyika.

Njira Yofunika Kwambiri: Sungani Vavu Yotsegula

Mukakhala gluing (zosungunulira kuwotcherera) valavu socket, valavuayenerakhalani pamalo otseguka kwathunthu. Zosungunulira mu primer ndi simenti zidapangidwa kuti zisungunuke PVC. Ngati valavu yatsekedwa, zosungunulirazi zimatha kutsekeka mkati mwa valavu ndikuwotcherera mpirawo mpaka mkati. Valovu idzatsekedwa kotheratu. Ndikuuza Budi kuti ichi ndi chifukwa choyamba cha "kulephera kwa valve yatsopano." Si vuto la valve; ndi cholakwika khazikitsa kuti ndi 100% kupewa.

Momwe mungamangirire valavu ya mpira wa PVC?

Mumathira guluu ndikumangiriza zigawozo, koma cholumikizira chimalephera kukakamiza. Izi zimachitika chifukwa "gluing" kwenikweni ndi mankhwala omwe amafunikira masitepe apadera.

Kuti mumamatire bwino valavu ya mpira wa PVC, muyenera kugwiritsa ntchito njira ziwiri zoyambira ndi simenti. Izi zimaphatikizapo kuyeretsa, kugwiritsa ntchito pulayimale yofiirira pamalo onse awiri, kenako ndikugwiritsa ntchito simenti ya PVC musanayilumikizane ndi zopindika.

Izi zimatchedwa kuwotcherera zosungunulira, ndipo zimapanga mgwirizano wamphamvu kuposa chitoliro chokha. Kudumpha masitepe ndi chitsimikizo cha kutayikira kwamtsogolo. Nayi njira yomwe timaphunzitsira ogawa a Budi kutsatira:

1. Dry Fit Choyamba.Onetsetsani kuti chitoliro chatsika mkati mwa socket ya valve.
2. Yeretsani Magawo Onse.Gwiritsani ntchito nsalu yoyera, youma kupukuta dothi kapena chinyezi kuchokera kunja kwa chitoliro ndi mkati mwa soketi ya valve.
3. Ikani Primer.Gwiritsani ntchito dauber kuti mugwiritse ntchito chovala chomasuka cha PVC choyambira kunja kwa chitoliro ndi mkati mwa socket. The primer imayeretsa pamwamba ndikuyamba kufewetsa pulasitiki. Iyi ndiye sitepe yodumphidwa kwambiri komanso yofunika kwambiri.
4. Ikani simenti.Pamene choyambira chikadali chonyowa, ikaninso simenti ya PVC pamalo oyambira. Osagwiritsa ntchito mochulukira, koma tsimikizirani kufalikira kwathunthu.
5. Gwirizanitsani ndi Kupotoza.Nthawi yomweyo kukankhira chitoliro mu socket mpaka pansi. Pamene mukukankhira, perekani kotala-kutembenukira. Kuyenda uku kumafalitsa simenti mofanana ndikuchotsa thovu lililonse lotsekeka.
6. Gwirani ndi Kuchiza.Gwirani mfundozo mwamphamvu kwa masekondi pafupifupi 30 kuti chitoliro chisatuluke. Osakhudza kapena kusokoneza mgwirizano kwa mphindi zosachepera 15, ndipo mulole kuti achire mokwanira molingana ndi malangizo a wopanga simenti musanakanikize dongosolo.

Kodi mumapangitsa bwanji kuti valavu ya mpira wa PVC ikhale yosavuta?

Vavu yanu yatsopano ndi yolimba kwambiri, ndipo mukuda nkhawa ndikudula chogwiriracho. Kuuma uku kungakupangitseni kuganiza kuti valavu ili ndi vuto pamene ilidi chizindikiro cha khalidwe.

Valavu yatsopano, yapamwamba kwambiri ya PVC ndi yolimba chifukwa mipando yake ya PTFE imapanga chisindikizo changwiro, cholimba pa mpira. Kuti izi zitheke, gwiritsani ntchito wrench pa nati ya square pamunsi pa chogwirira kuti muthe kuthyolako bwino.

Ndimamva funso ili nthawi zonse. Makasitomala amalandira Pntek yathumavavundi kunena kuti ndizovuta kwambiri kuzitembenuza. Izi ndi dala. Mphete zoyera mkati, mipando ya PTFE, imapangidwa mwatsatanetsatane kuti ipange chisindikizo cholimba. Kuthina kumeneko ndi komwe kumalepheretsa kutulutsa. Ma valve otsika mtengo okhala ndi zisindikizo zotayirira amatembenuka mosavuta, koma amalephera msanga. Ganizirani ngati nsapato zatsopano zachikopa; Ayenera kuthyoledwa. Njira yabwino yochitira izi ndi kugwiritsa ntchito wrench yaying'ono yosinthika pagawo lokhuthala, lalikulu la chogwiriracho, pansi pomwe. Izi zimakupatsani mwayi wochulukirapo popanda kuyika kupsinjika pa T-handle yokha. Mukatsegula ndi kutseka kangapo, zimakhala bwino kwambiri.Osagwiritsa ntchito WD-40 kapena mafuta ena opangira mafuta.Zogulitsazi zimatha kuukira ndi kufooketsa pulasitiki ya PVC ndi zisindikizo za EPDM O-ring, zomwe zimapangitsa kuti valve iwonongeke pakapita nthawi.

Mapeto

Kuyika koyenera, kugwiritsa ntchito njira yoyenera yolumikizira, kuwongolera, ndi njira yolumikizira, ndiyo njira yokhayo yotsimikizira aValve ya mpira wa PVCimapereka moyo wautali, wodalirika, wopanda kutayikira.
