Unamathisele iveluvu yakho entsha ye-PVC epayipini, kodwa manje iyavuza. Ijoyinti elilodwa elibi lisho ukuthi kufanele unqamule ipayipi bese uqala kabusha, umosha isikhathi nemali.

Ukufaka kahle iI-valve yebhola ye-PVC, kufanele usebenzise i-primer eqondene ne-PVC futhiusimende we-solvent. Le ndlela ihilela ukusika ipayipi lihlanzeke, likhishwe, licwebezelise zombili izindawo, lifake usimende, bese liphusha futhi libambe ilunga liqine imizuzwana engu-30 ukuze kwakheke ukushisela kwamakhemikhali unomphela.

Le nqubo imayelana nokudala isibopho samakhemikhali esiqine njengepayipi ngokwalo, hhayi nje ukuhlanganisa izingxenye ndawonye. Kuyisihloko esibalulekile engihlala ngisigcizelela nozakwethu, njengo-Budi, umphathi wokuthenga e-Indonesia. Amakhasimende akhe, kusukela kosonkontileka abakhulu kuya kubathengisi bendawo, awakwazi ukukhokhela ukwehluleka. Ijoyinti elilodwa elibi lingacwilisa umugqa wesikhathi wephrojekthi kanye nesabelomali. Ake sihlole imibuzo ebalulekile ukuze siqinisekise ukuthi konke ukufakwa okuphathayo kuba yimpumelelo ehlala isikhathi eside.

Uyifaka kanjani i-valve yebhola kupayipi le-PVC?

Unezingxenye ezifanele, kodwa uyazi ukuthi awekho amathuba esibili ngosimende we-PVC. Iphutha elilodwa elincane lisho ukusika ingxenye yepayipi bese uqala phansi kusukela ekuqaleni.

Inqubo yokufaka isebenzisa i-solvent welding futhi ihilela izinyathelo ezinhlanu ezibalulekile: ukusika isikwele sepayipi, ukukhipha imiphetho, ukusebenzisa i-PVC primer kuzo zombili izindawo, ukumboza ngosimende we-PVC, bese ucindezela izingxenye ndawonye ngokujika kwekota futhi uzibambe ngokuqinile.

Ukulungisa le nqubo yikho okuhlukanisa umsebenzi wochwepheshe nenkinga yesikhathi esizayo. Ake sihlaziye isinyathelo ngasinye ngokuningiliziwe. Lena inqubo eqondile engiyinikeza amaklayenti kaBudi ukuze ngiqinisekise uphawu oluhle.

1. Cut & Deburr:Qala ngokusikwa okuhlanzekile, kwesikwele epayipini lakho. Noma iyiphi i-engeli ingadala igebe ekuhlanganyeleni. Ngemva kokusika, sebenzisa ithuluzi lokususa noma ummese olula ukuze uphuce noma iyiphi i-fuzz yepulasitiki ngaphakathi nangaphandle konqenqema lwepayipi. Lawa mabhula angakhuhla usimende futhi avimbele ipayipi ukuthi lihlale ngokugcwele.
2. Okuyinhloko:Faka ijazi elikhululekile leI-PVC yokuqala(imvamisa iba nsomi) ukuya ngaphandle kwepayipi nangaphakathi kwesokhethi yevalvu. Ungaseqi lesi sinyathelo! I-Primer ayiyona nje into yokuhlanza; iqala ukuthambisa ipulasitiki, ilungiselele ukushisela amakhemikhali.
3. Usimende:Ngenkathi i-primer isemanzi, sebenzisa ungqimba olulinganayo lwePVC usimendephezu kwezindawo ezishibhile. Yigcobe epayipini kuqala, bese unikeza isokhethi yevalvu ijazi elincanyana.
4. Phusha, Phenduka futhi Ubambe:Ngokushesha cindezela ipayipi esokhethini nge-twist encane yekota. Lokhu kusonta kusiza ukusabalalisa usimende ngokulinganayo. Ngemuva kwalokho kufanele ubambe iqhaza ndawonye ngokuqinile okungenani imizuzwana engama-30. Ukusabela kwamakhemikhali kudala ingcindezi ezozama ukuphusha ipayipi liphume.

Iyiphi indlela efanele yokufaka i-valve yebhola?

I-valve ingaphakathi, kodwa isibambo sishaya odongeni. Noma okubi nakakhulu, ufake i-valve ye-union yeqiniso eduze kakhulu kokunye okufanelekile ukuthi awukwazi ukuthola isikrufu kumantongomane.

"Indlela efanele" yokufaka i-valve yebhola icabangela ukusetshenziswa kwesikhathi esizayo. Lokhu kusho ukuqinisekisa ukuthi isibambo sinemvume egcwele engama-degree angu-90 ukuze sijike nokuthi amantongomane enyunyana kuvalvu yenyunyana yangempela afinyeleleka ngokuphelele ukuze agcinwe isikhathi esizayo.

Ukufakwa okuyimpumelelo kungaphezu nje kwe-auphawu olungavuzi; imayelana nokusebenza kwesikhathi eside. Yilapho ukuhlela okuncane kwenza umehluko omkhulu. Iphutha elivame kakhulu engilibonayo ukuntula ukuhlela ukufinyelela. I-valve yebhola kufanele ijikelezise ngamadigri angu-90 ukuze isuke ekuvulekeni ngokuphelele iye kokuvaleka ngokugcwele. Ngaphambi kokuthi uvule ngisho nekani likasimende, bamba i-valve endaweni bese ushwiba isibambo phakathi nohlu lwaso olugcwele lokunyakaza. Qiniseka ukuthi ayishayi udonga, elinye ipayipi, nanoma yini enye. Iphuzu lesibili, ikakhulukazi iPntek yethuama-valve eqiniso, ukufinyelela inyunyana. Inzuzo yonke yomklamo wenyunyana weqiniso ukuthi ungakwazi ukukhulula izinyunyana futhi uphakamise umzimba omkhulu ukuze ulungiswe noma ushintshwe ngaphandle kokusika ipayipi. Ngihlale ngikhumbuza uBudi ukuthi agcizelele lokhu kumakhasimende akhe osonkontileka. Uma ufaka i-valve lapho ungeke ukwazi ukuthola isikrufu kulawo mantongomane, usanda kuguqula ivalvu eyi-premium, esebenzisekayo ibe esezingeni, elahlayo.

Uxhuma kanjani i-valve kwipayipi le-PVC?

I-valve yakho inezintambo, kodwa ipayipi lakho libushelelezi. Uyazibuza ukuthi kufanele yini uyinamathisele, uyixhume, noma enye indlela ingcono kunenye ukuze ube nokuxhumana okuqinile.

Kunezindlela ezimbili eziyinhloko: i-solvent welding (i-gluing) yebhondi ehlala njalo, ehlanganisiwe, kanye nokuxhumana okunentambo kwelunga elingakwazi ukuhlakazeka. Kuzinhlelo ze-PVC-to-PVC, i-solvent welding iyindlela enamandla futhi evamile.

Ukukhetha uhlobo lokuxhumana olulungile kubalulekile. Iningi lamasistimu e-PVC athembele kuwoukushisela i-solvent, futhi ngesizathu esihle. Ayigcini nje ngokuhlanganisa izingxenye; iwahlanganisa ngamakhemikhali abe yipulasitiki eyodwa, engenamthungo eqine ngendlela emangalisayo futhi engavuzi. Ukuxhumana okunemicu kunendawo yakho, kodwa futhi kunobuthakathaka. Ziwusizo lapho uxhuma i-valve ye-PVC empompini yensimbi noma ithangi elivele linezintambo. Kodwa-ke, ukuxhunywa kwepulasitiki okufakwe imicu kungaba umthombo wokuvuza uma kungavalwanga kahle nge-Teflon tape noma unamathisele. Okubaluleke nakakhulu, ukuqinisa ngokweqile ukufakwa kwepulasitiki okufakwe imicu kuyiphutha elivamile elingase kuqhekeke ukuxhumana kwabesifazane, kubangele ukwehluleka.

Ukuqhathanisa Indlela Yokuxhuma

Ingabe ama-valve ebhola e-PVC aqondise?

Usimende usulungile, kodwa uyangabaza, ufuna umcibisholo emzimbeni we-valve. Ukunamathisela i-valve eqondisayo emuva kungaba iphutha elibizayo, okukuphoqa ukuthi uyibhubhise.

Cha, ivalvu yebhola ye-PVC ejwayelekile inama-bi-directional futhi izovala ukugeleza ngokulinganayo ukusuka kunoma iyiphi indlela. Umsebenzi wayo awuncikile ku-flow orientation. Okuwukuphela "kwesiqondiso" esibalulekile ukuyifaka ukuze ukwazi ukufinyelela isibambo namantongomane enyunyana.

Lona umbuzo omuhle okhombisa ukucabanga ngokucophelela. Uqinisile ukuthi uqaphe, njengoba amanye ama-valve aqondisa ngokuphelele. Ahlola i-valve, isibonelo, ivumela kuphela ukugeleza endaweni eyodwa futhi izoba nomcibisholo ocacile ophrintiwe kuyo. Uma ifakwe emuva, ngeke isebenze. Nokho, aama-valve ebholaidizayini i-symmetrical. Inebhola elinembobo elivaleka esihlalweni. Njengoba kunesihlalo kuzo zombili izinhlangothi ezikhuphuka nomfula, i-valve ivala kahle kungakhathaliseki ukuthi amanzi ageleza ngayiphi indlela. Ngakho-ke, awukwazi ukuyifaka “emuva” ngokuya ngokugeleza. Njengoba ngishilo ngaphambili, ukuphela "kwesiqondiso" okudingeka ukhathazeke ngakho ukuqondiswa okusebenzayo kokusebenzisa i-valve. Ungakwazi yini ukuphendula isibambo? Ungakwazi yini ukufinyelela izinyunyana? Lokho ukuhlolwa kweqiniso kokufakwa okulungile kwevalvu yekhwalithi njengale esikhiqiza ePntek.

Isiphetho

Ukuze uthole ukufakwa okuphelele kwe-valve yebhola ye-PVC, sebenzisa i-primer efanele kanye nosimende. Hlela isibambo kanye nokufinyelela kwamantongomane enyunyana ukuze uqinisekise ukuxhumana okuthembekile, okungavuzi, nokusebenzisekayo.
