Ufake ngokucophelela ivalve entsha ye-PVC enentambo, kodwa iconsa kancane isuka emicu. Ukuyiqinisa kakhulu kuzwakala kuyingozi, njengoba wazi ukuthi ukujika okukodwa okuningi kungahlephula ukufaneleka.

Ukuze ufake ngempumelelo i-valve yebhola ye-PVC enentambo, bopha izintambo zesilisa ngezendlalelo ezingu-3-4 ze-Teflon tape. Ngaso sonke isikhathi bopha ngendlela yokuqinisa. Bese, uyibophe ngesandla uyiqinise, futhi usebenzise isikrufu ukujika okukodwa noma okubili kokugcina.

Intambo evuzayo ingenye yezinkinga ezivame kakhulu nezikhungathekisayo zokufaka. Cishe njalo kubangelwa iphutha elincane, eligwemekayo ekulungiseleleni noma ekuqiniseni. Ngivame ukuxoxa ngalokhu nozakwethu e-Indonesia, e-Budi, ngoba kuyinkinga ebuhlungu njalo amakhasimende akhe abhekana nayo. Uxhumano oluvikelekile, olungavuziyo oluluchungechunge kulula ukulufinyelela. Udinga nje ukulandela izinyathelo ezimbalwa ezilula, kodwa ezibucayi kakhulu. Ake siphendule imibuzo ebalulekile ukuze silungise ngaso sonke isikhathi.

Ungakufaka kanjani ukufakwa kwepayipi le-PVC elinentambo?

Usebenzise intambo yokunamathisela isivalo esebenza kahle ensimbi, kodwa ukufaka kwakho kwe-PVC kusavuza. Okubi nakakhulu, ukhathazeka ngokuthi amakhemikhali akunamathisele angase alimaze ipulasitiki ngokuhamba kwesikhathi.

Nge-PVC ewuchungechunge, sebenzisa njalo i-Teflon tape esikhundleni se-dope yepayipi noma unamathisele. Gcoba izintambo zesilisa izikhathi ezingu-3-4 ngendlela efanayo uzoqinisa ukufaneleka, uqinisekise ukuthi i-tape ibeka isicaba futhi ibushelelezi ukuze udale uphawu oluphelele.

Lo mehluko phakathi kwe-tape nokunamathisela ubalulekile ekufakweni kwepulasitiki. Eziningi ezivamileamapayipi amapayipiziqukethe izinhlanganisela ezisekelwe ku-petroleum ezingahlasela i-PVC ngamakhemikhali, iyenze ibe brittle futhi ingase iqhekeke ngaphansi kwengcindezi evamile yokusebenza.I-teflon tape, ngakolunye uhlangothi, ayisebenzi ngokuphelele. Isebenza njenge-sealant kanye ne-lubricant, igcwalisa izikhala ezincane emicu ngaphandle kokudala ukucindezela kwangaphandle okuyingozi okunganamathisela. Lokhu kuvimbela ukucindezeleka kokufaneleka kwabesifazane.

I-Sealant Choice ye-PVC Threads

Uma ugoqa izintambo, hlala uhambe ngendlela yewashi njengoba ubheka ekugcineni kokufaka. Lokhu kuqinisekisa ukuthi njengoba uqinisa i-valve, i-tape ihlehliswa phansi kunokuba ihlanganiswe futhi iqaqa.

Indlela yokufaka i-valve yebhola kupayipi le-PVC?

Une-valve yebhola enentambo kodwa ipayipi lakho libushelelezi. Udinga ukuwaxhuma, kodwa uyazi ukuthi awukwazi ukunamathisela izintambo noma ukuxhuma ipayipi elibushelelezi. Yikuphi ukulinganisa okulungile?

Ukuze uxhume i-valve yebhola enentambo epayipini le-PVC elibushelelezi, kufanele uqale u-solvent-weld (unamathisele) i-adaptha enentambo yesilisa ye-PVC epayipini. Ngemva kokuthi usimende selaphe ngokugcwele, ungakwazi ukufaka i-valve enentambo ku-adaptha.

Awukwazi ukudala imicu kupayipi le-PVC elijwayelekile, elibushelelezi; udonga luncane kakhulu futhi luzohluleka ngokushesha. Ukuxhumana kufanele kwenziwe ngokufakwa kwe-adaptha efanele. Kulo msebenzi, udinga aI-adaptha yesilisa ye-PVC(okuvame ukubizwa ngokuthi i-adaptha ye-MPT noma ye-MIPT). Olunye uhlangothi lunesokhethi elibushelelezi, kanti olunye lulolonge izintambo zesilisa. Usebenzisa i-primer ye-PVC ejwayelekile kanye nenqubo kasimende ukushisela isiphetho sesokhethi ngamakhemikhali epayipini lakho, udale ucezu olulodwa, oluhlanganisiwe. Okubalulekile lapha ukubekezela. Kufanele ukuvumele lokhoukwelashwa kwe-solvent-weldngokuphelele ngaphambi kokufaka noma iyiphi i-torque emicu. Ukusebenzisa amandla kusenesikhathi kunganqamula isibopho samakhemikhali esisha, kudale ukuvuza kwelunga elinamathiselwe. Ngihlale ngeluleka amaklayenti kaBudi ukuthi alinde okungenani amahora angama-24 ukuze aphephe.

Indlela yokufaka i-valve enentambo?

Uqinise i-valve yakho entsha enentambo kuze kube yilapho izwakala iqinile, wezwa nje ukuqhekeka okugulayo. Manje i-valve yonakele, futhi kufanele uyinqume futhi uqale phansi.

Indlela elungile yokuqinisa ithi "qinisa isandla kanye nokujika okukodwa kuya kokubili." Vele ujike i-valve ngesandla ize iqine, bese usebenzisa isikrufu ukuze uyinike ithuba elilodwa noma amabili okugcina. Ima lapho.

Ukuqinisa ngokweqile kuyimbangela yokuqala yokwehluleka kokufakwa kwepulasitiki okufakwe imicu. Ngokungafani nensimbi, enganwebeka futhi ikhubaze, i-PVC iqinile. Uma uginqa phansi kuvalvu ye-PVC enentambo, ubeka amandla amakhulu angaphandle ezindongeni zokufakelwa kwabesifazane, uzama ukuyihlukanisa ivuleke. I-“qinisa isandla kanye nokuphenduka okukodwa kuya kwamabili"Umthetho uyindinganiso yegolide yesizathu. Ukuqinisa isandla kukodwa kwenza imicu ibambene kahle. Ukujika okukodwa noma okubili kokugcina ngesikrufu kwanele nje ukucindezela izendlalelo zeteyiphu ye-Teflon, okudala uphawu oluqinile, olungafaki amanzi ngaphandle kokufaka ingcindezi eyingozi kupulasitiki. Ngihlale ngitshela ozakwethu ukuthi "ukuqina" akuncono nge-PVCs. iminyaka.

Indlela yokuxhuma i-valve yokuvala ku-PVC?

Udinga ukungeza ukuvala kulayini okhona we-PVC. Awunaso isiqiniseko sokuthi kufanele usebenzise ivalve enentambo noma ivalve ejwayelekile enamathiselwe kulolu hlelo lokusebenza.

Ukwengeza ukuvala kulayini we-PVC okhona, i-valve yebhola lenyunyana yeqiniso iyindlela engcono kakhulu. Ivumela ukulungiswa kwesikhathi esizayo. Sebenzisa inguqulo ye-solvent-weld (isokhethi) kumasistimu ahlanzekile e-PVC, noma inguqulo enentambo uma uxhumeka eduze kwezingxenye zensimbi.

Uma udinga ukusika umugqa ukuze wengeze ukuvala, ukucabanga ngekusasa kubalulekile. I-valve yebhola ye-union yangempela iyona engcono kakhulu lapha. Ungasika ipayipi, unamathisele iziphetho ezimbili zenyunyana, bese ufaka umzimba we-valve phakathi kwazo. Lokhu kungcono kakhulu kunevalvu ejwayelekile ngoba ungavele uvule amantongomane enyunyana ukuze ususe wonke ama-valve ukuze ahlanzwe noma afakwe esikhundleni ngaphandle kokuphinda usike ipayipi. Uma isistimu yakho iyi-PVC engu-100%, ivalve ye-solvent-weld (isokhethi) ye-union yeqiniso iphelele. Uma ungeza ukuvala eduze kwepompo noma isihlungi esinezintambo zensimbi, bese kuba yintamboi-valve ye-union yeqinisoindlela yokuhamba. Unganamathisela i-adaptha enentambo epayipini le-PVC kuqala, bese ufaka i-valve. Lokhu kuvumelana nezimo yingakho thina kwaPntek sigcizelela kakhulu ukwakheka kwenyunyana yeqiniso.

Isiphetho

Ukuze ufake kahle intamboI-valve yebhola ye-PVC, sebenzisa i-Teflon tape, hhayi ukunamathisela. Qinisa ngesandla kuqala, bese wengeza ukujika okukodwa noma amabili ngaphezulu ngesikrufu sophawu oluhle.
