Unamathisele ivalvu yakho entsha ye-PVC epayipini, kodwa manje iyavuza. Ijoyinti elilodwa elibi lisho ukuthi kufanele usike ipayipi bese uqala kabusha, uchitha isikhathi nemali.
Ukufaka kahle i-I-valve yebhola ye-PVC, kumele usebenzise i-primer eqondene ne-PVC kanyeusimende we-solventLe ndlela ihilela ukusika ipayipi lihlanzeke, ukususa ukusha, ukugawula izindawo zombili, ukufaka usimende, bese ucindezela futhi ubambe ijoyinti ngokuqinile imizuzwana engama-30 ukuze kudalwe ukushiswa kwamakhemikhali okuhlala njalo.
Le nqubo imayelana nokudala isibopho samakhemikhali esiqinile njengepayipi uqobo, hhayi nje ukunamathela izingxenye ndawonye. Yisihloko esibalulekile engisigcizelela njalo kubalingani bami, njengoBudi, umphathi wokuthenga e-Indonesia. Amaklayenti akhe, kusukela kosonkontileka abakhulu kuya kubathengisi bendawo, abakwazi ukukhokhela ukwehluleka. Inhlanganisela eyodwa embi ingalimaza isikhathi sephrojekthi kanye nesabelomali. Ake sihambe ngemibuzo ebalulekile ukuqinisekisa ukuthi konke ukufakwa okusingathayo kuyimpumelelo ehlala isikhathi eside.
Uyifaka kanjani ivalvu yebhola epayipini le-PVC?
Unezingxenye ezifanele, kodwa uyazi ukuthi awekho amathuba esibili nge-PVC cement. Iphutha elilodwa elincane lisho ukusika ingxenye yepayipi bese uqala phansi.
Inqubo yokufaka isebenzisa ukushisela kwe-solvent futhi ihilela izinyathelo ezinhlanu ezibalulekile: ukusika isikwele sepayipi, ukususa amabhodwe emaphethelweni, ukufaka i-primer ye-PVC ezindaweni zombili, ukumboza nge-PVC cement, bese ucindezela izingxenye ndawonye ngokujika kwekota bese uzibamba ziqine.
Ukulungisa le nqubo yikho okuhlukanisa umsebenzi wobungcweti nenkinga yesikhathi esizayo. Ake sihlaziye isinyathelo ngasinye ngokuningiliziwe. Lena inqubo eqondile engiyinikeza amakhasimende kaBudi ukuqinisekisa uphawu oluphelele.
- Sika futhi Ususe I-Burr:Qala ngokusika okuhlanzekile, okuyisikwele epayipini lakho. Noma yiliphi i-engeli lingadala isikhala esihlanganyelweni. Ngemva kokusika, sebenzisa ithuluzi lokususa ukubhoboza noma ummese olula ukuze usule noma yikuphi ukugoba kwepulasitiki ngaphakathi nangaphandle komphetho wepayipi. Lawa ma-burrs angakhuhla usimende futhi avimbele ipayipi ukuthi lingahlali ngokuphelele.
- Okuyinhloko:Faka ingubo ye-liberal yeI-primer ye-PVC(ngokuvamile kuba nsomi) ngaphandle kwepayipi kanye nangaphakathi kwesokhethi yevalvu. Ungasiqedi lesi sinyathelo! I-primer ayisiyona nje into yokuhlanza; iqala ukuthambisa ipulasitiki, iyilungiselele ukushintshwa kwamakhemikhali.
- Usimende:Ngesikhathi i-primer isemanzi, faka ungqimba olulinganayo lwe-Usimende we-PVCphezu kwezindawo ezilungisiwe. Yifake epayipini kuqala, bese unikeza isokhethi yevalvu ungqimba oluncane.
- Cindezela, Jika bese Ubamba:Faka ipayipi ngokushesha endaweni yokubeka ngokushintsha okuncane kwekota. Lokhu kujika kusiza ukusabalalisa usimende ngokulinganayo. Ngemuva kwalokho kumele ubambe ijoyinti ndawonye ngokuqinile okungenani imizuzwana engama-30. Ukusabela kwamakhemikhali kudala ingcindezi ezozama ukusunduza ipayipi liphume.
Iyiphi indlela efanele yokufaka i-ball valve?
Ivalvu ifakiwe, kodwa isibambo sishaya odongeni. Noma okubi nakakhulu, ufake ivalvu yokuhlanganisa yangempela eduze kakhulu nenye into yokuthi awukwazi ukufaka isikrufu kumantongomane.
"Indlela efanele" yokufaka ivalvu yebhola icabangela ukusetshenziswa kwesikhathi esizayo. Lokhu kusho ukuqinisekisa ukuthi isibambo sinendawo ephelele yokujika engama-degree angu-90 nokuthi ama-union nuts kuvalvu ye-union yangempela ayatholakala ngokuphelele ukuze agcinwe isikhathi esizayo.
Ukufakwa okuphumelelayo kungaphezu nje kwe-uphawu olungavuzi; kumayelana nokusebenza kwesikhathi eside. Yilapho ukuhlela okuncane kwenza khona umehluko omkhulu. Iphutha elivame kakhulu engilibonayo ukuntuleka kokuhlela ukufinyelela. Ivalvu yebhola kumele ijikeleze ama-degree angu-90 ukuze isuke ekuvulekeni ngokuphelele iye ekuvalekeni ngokuphelele. Ngaphambi kokuthi uvule ngisho nethini likasimende, bamba ivalvu endaweni yayo bese ushwiba isibambo ngokusebenzisa uhla lwayo oluphelele lokunyakaza. Qiniseka ukuthi ayishayi odongeni, kwenye ipayipi, noma yini enye. Iphuzu lesibili, ikakhulukazi le-Pntek yethuama-valve e-union yangempela, ukufinyelela kweyuniyoni. Inzuzo ephelele yomklamo weyuniyoni wangempela ukuthi ungavula amayuniyoni bese uphakamisa umzimba oyinhloko ukuze ulungiswe noma ushintshwe ngaphandle kokusika ipayipi. Ngihlala ngikhumbuza uBudi ukuthi agcizelele lokhu kumakhasimende akhe onkontileka. Uma ufaka ivalvu lapho ungakwazi ukuthola khona isikrufu kulawo manothi, usanda kuguqula ivalvu esezingeni eliphezulu, elungisekayo ibe yivalvu ejwayelekile, elahlwayo.
Uxhuma kanjani i-valve epayipini le-PVC?
Ivalvu yakho inezintambo, kodwa ipayipi lakho libushelelezi. Uzibuza ukuthi kufanele ulinamathisele, ulifake intambo, noma ukuthi indlela eyodwa ingcono kunenye ukuze uthole uxhumano oluqinile.
Kunezindlela ezimbili eziyinhloko: ukushisela i-solvent (ukunamathisela) ukuze kube nesibopho esihlala njalo, esihlanganisiwe, kanye nokuxhumeka okunezintambo kwejoyinti elingahlukaniswa. Kumasistimu e-PVC-to-PVC, ukushisela i-solvent kuyindlela enamandla futhi evame kakhulu.
Ukukhetha uhlobo lokuxhuma olufanele kubalulekile. Iningi lezinhlelo ze-PVC lithembele ku-ukushisela i-solvent, futhi ngesizathu esihle. Ayigcini nje ngokunamathisela izingxenye ndawonye; izihlanganisa ngamakhemikhali zibe yingcezu eyodwa yepulasitiki engenamthungo eqinile kakhulu futhi engavuzi. Ukuxhumeka okunezintambo kunendawo yayo, kodwa futhi kunobuthakathaka. Kuwusizo lapho kuxhuma ivalvu ye-PVC kuphampu yensimbi noma ithangi elivele linezintambo. Kodwa-ke, ukuxhumeka kwepulasitiki okunezintambo kungaba umthombo wokuvuza uma kungavaliwe kahle ngeteyipu ye-Teflon noma i-paste. Okubaluleke kakhulu, ukuqinisa kakhulu i-fitting yepulasitiki enesintambo kuyiphutha elivamile elingaphula uxhumano lwabesifazane, okubangela ukwehluleka.
Ukuqhathaniswa Kwendlela Yokuxhumana
| Isici | I-Solvent Weld (Isokhethi) | Okunentambo (MPT/FPT) |
|---|---|---|
| Amandla | Okuhle Kakhulu (I-Fused Joint) | Kuhle (Iphuzu elingase libe buthaka) |
| Ukuthembeka | Kuhle kakhulu | Kuhle (Kuthambekele ekuqiniseni ngokweqile) |
| Ukusetshenziswa Okuhle Kakhulu | Ukuxhumeka kwe-PVC kuya ku-PVC | Ukuxhuma i-PVC kwizintambo zensimbi |
| Uhlobo | Uhlala Njalo | Ingalungiseka (iyasuswa) |
Ingabe ama-valve ebhola e-PVC aqonde ngqo?
Usimende usulungile, kodwa uyanqikaza, ufuna umcibisholo emzimbeni wevalvu. Ukunamathisela ivalvu eqondisa emuva kungaba yiphutha elibizayo, okukuphoqa ukuthi ulibhubhise.
Cha, ivalvu yebhola ye-PVC ejwayelekile iqondiswa kabili futhi izovala ukugeleza ngokulinganayo kusuka kunoma iyiphi indlela. Umsebenzi wayo awuxhomekile ekuqondeni kokugeleza. Okuwukuphela "kwendlela" ebalulekile ukuyifaka ukuze ukwazi ukufinyelela isibambo kanye nama-union nuts.
Lona umbuzo omuhle okhombisa ukucabanga ngokucophelela. Ulungile ngokuqapha, njengoba amanye ama-valve eqondisa ngqo.ivalvu yokuhlola, isibonelo, ivumela ukugeleza ohlangothini olulodwa kuphela futhi izoba nomcibisholo ocacile ophrintiwe kuyo. Uma ifakwe emuva, ngeke isebenze. Kodwa-ke, i-amavalvu ebholaUmklamo ulingana. Inebhola elinembobo ngaphakathi elivala isihlalo. Njengoba kunesihlalo ezinhlangothini zombili eziphezulu nangezansi komfula, ivalvu ivala kahle kungakhathaliseki ukuthi amanzi ageleza ngakuphi. Ngakho-ke, awukwazi ukuyifaka "emuva" maqondana nokugeleza. Njengoba ngishilo ngaphambili, okuwukuphela "kwesiqondiso" okudingeka ukhathazeke ngaso ukuqondiswa okusebenzayo kokusebenzisa ivalvu. Ungakwazi yini ukujika isibambo? Ungakwazi yini ukufinyelela ama-union? Leso isivivinyo sangempela sokufakwa okufanele kwevalvu yekhwalithi efana naleyo esiyikhiqizayo kwa-Pntek.
Isiphetho
Ukuze ufake i-PVC ball valve ephelele, sebenzisa i-primer kanye ne-samente efanele. Hlela ukufinyelela kwe-handle kanye ne-union nut ukuqinisekisa ukuxhumana okuthembekile, okungenamanzi, nokulungisekayo.
