Uncamathelise ivalve yakho entsha yePVC kumbhobho, kodwa ngoku iyavuza. Ilungu elinye elibi lithetha ukuba kufuneka unqumle umbhobho kwaye uqale phantsi, uchithe ixesha kunye nemali.

Ukufakela ngokufanelekileyo iIvalve yebhola yePVC, kufuneka usebenzise i-PVC-specific primer kunyeisamente enyibilikayo. Indlela ibandakanya ukusika umbhobho ucocekile, ugxothwe, uhlambulule imiphezulu yomibini, ugalele isamente, emva koko utyhale kwaye ubambe umdibaniso ngokuqinileyo imizuzwana engama-30 ukwenza i-weld yekhemikhali esisigxina.

Le nkqubo imalunga nokudala iqhina lekhemikhali elinamandla njengombhobho ngokwawo, hayi nje ukuncamathela iindawo ndawonye. Sisihloko esibalulekileyo endihlala ndisigxininisa kumaqabane am, njengoBudi, umphathi wokuthenga e-Indonesia. Abathengi bakhe, ukusuka kwiikontraka ezinkulu ukuya kubathengisi basekhaya, abanako ukufikelela kwiintsilelo. Idibaniso elinye elibi lisenokutshonisa ixesha leprojekthi kunye nohlahlo lwabiwo-mali. Masihambe ngemibuzo engundoqo ukuqinisekisa ukuba ufakelo ngalunye olubambayo luyimpumelelo ehlala ixesha elide.

Uyifaka njani ivalve yebhola kumbhobho wePVC?

Unamalungu afanelekileyo, kodwa uyazi ukuba akukho mathuba esibini ngesamente yePVC. Impazamo enye encinci ithetha ukusika icandelo lombhobho kwaye uqale ukusuka ekuqaleni.

Inkqubo yokufakela isebenzisa i-welding ye-solvent kwaye ibandakanya amanyathelo amahlanu angundoqo: ukusika isikwere sombhobho, ukucima imiphetho, ukusebenzisa i-PVC primer kuzo zombini iindawo, ukugquma nge-samente ye-PVC, kwaye emva koko utyhala iindawo kunye nokujika kwekota kwaye uzibambe ngokuqinileyo.

Ukufumana le nkqubo ngokufanelekileyo kuko okwahlula umsebenzi oqeqeshiweyo kwingxaki ezayo. Masicazulule inyathelo ngalinye ngokweenkcukacha. Le yeyona nkqubo ndiyinikezela kubathengi bakaBudi ukuqinisekisa itywina eligqibeleleyo.

1. Sika & Deburr:Qala ngokucoceka, ukusika isikwere kumbhobho wakho. Nayiphi na i-angle inokudala i-gap kwi-joint. Emva kokusika, sebenzisa isixhobo sokuqhawula okanye imela elula ukucheba nayiphi na i-fuzz yeplastiki ngaphakathi nangaphandle komphetho wombhobho. Ezi burrs zinokukhuhla isamente kwaye zithintele umbhobho ukuba ungahlali ngokupheleleyo.
2. Prime:Faka idyasi yenkululeko yeIsiseko sePVC(idla ngokuba mfusa) ukuya ngaphandle kombhobho kunye nangaphakathi kwisokethi yevalve. Musa ukutsiba eli nyathelo! Iprimer ayisosicoci nje; iqala ukuthambisa iplastiki, ukuyilungiselela i-weld yekhemikhali.
3. Isamente:Ngelixa i-primer isemanzi, sebenzisa umaleko olinganayoPVC isamentekwiindawo eziphakamileyo. Yifake kumbhobho kuqala, emva koko unike isokhethi yevalve idyasi ebhityileyo.
4. Tyhala, Jika kwaye Ubambe:Ngokukhawuleza tyhala umbhobho kwi-socket kunye ne-quarter-turn twist encinci. Le twist inceda ukusasaza isamente ngokulinganayo. Emva koko kufuneka ubambe eli lungu kunye ngokuqinileyo imizuzwana engama-30 ubuncinane. Ukusabela kweekhemikhali kuvelisa uxinzelelo oluya kuzama ukutyhala umbhobho ngaphandle.

Yeyiphi indlela eyiyo yokufakela ivalve yebhola?

Ivalve ingaphakathi, kodwa isiphatho sibetha eludongeni. Okanye okubi ngakumbi, ufake ivalve yomanyano yokwenyani kufutshane nenye into efanelekileyo kangangokuba awukwazi ukufumana isitshixo kwiintongomane.

"Indlela echanekileyo" yokufakela ivalve yebhola iqwalasela ukusetyenziswa kwexesha elizayo. Oku kuthetha ukuqinisekisa ukuba isiphatho sine-90-degree clearance epheleleyo ukuze sijike kwaye amandongomane omanyano kwivalvu yomanyano yokwenene afikeleleke ngokupheleleyo ukulungiselela ulondolozo lwexesha elizayo.

Ufakelo oluyimpumelelo lumalunga nokungaphezulu nje kweitywina elingavuziyo; imalunga nokusebenza kwexesha elide. Apha kulapho isicwangciso esincinci senza umahluko omkhulu. Eyona mpazamo ixhaphakileyo ndiyibonayo kukunqongophala kwesicwangciso sokufikelela. Ivalve yebhola kufuneka ijikethe ama-90 degrees ukusuka ekuvulekeni ukuya ekuvaleni ngokupheleleyo. Ngaphambi kokuba uvule itoti yesamente, bamba ivalve endaweni kwaye ujiwule isiphatho kuluhlu olupheleleyo lwentshukumo. Qinisekisa ukuba ayibethi eludongeni, omnye umbhobho, okanye nantoni na eyenye. Inqaku lesibini, ngakumbi kwiPntek yethuiivalvu zomanyano lokwenyani, kukufikelela kwimanyano. Inzuzo yonke yoyilo lomanyano lwenyani kukuba unokukhulula iimanyano kwaye uphakamise umzimba oyintloko ukuze ulungiswe okanye utshintshe ngaphandle kokusika umbhobho. Ndihlala ndimkhumbuza uBudi ukuba agxininise oku kubathengi bakhe bekontraka. Ukuba ufaka ivalve apho ungenako ukufumana isiklintshi kwezo nuts, ujike nje ipremiyamu, ivalve enokusetyenzwa ibe yinto eqhelekileyo, elahlayo.

Udibanisa njani ivalve kumbhobho wePVC?

Ivalve yakho ineentambo, kodwa umbhobho wakho ugudile. Uyazibuza ukuba kufuneka uyincamathelise, uyithulule, okanye ukuba enye indlela ingcono kunenye kunxibelelwano oluqinileyo.

Kukho iindlela ezimbini eziphambili: i-solvent welding (i-gluing) yesigxina, ibhondi edibeneyo, kunye nokudibanisa okufakwe kwi-joint enokutshatyalaliswa. Kwiinkqubo zePVC ukuya kwi-PVC, ukuwelda kwe-solvent yeyona ndlela inamandla kwaye ixhaphake ngakumbi.

Ukukhetha uhlobo loqhagamshelwano olululo lubalulekile. Uninzi lweenkqubo zePVC zithembeleukuwelda okunyibilikayo, yaye ngesizathu esivakalayo. Ayinamatheli nje amalungu ndawonye; idibanisa ngokwekhemikhali ibe yiplastiki enye, engenamthungo eyomelele ngokumangalisayo kwaye ingavuzi. Unxibelelwano olunemisonto lunendawo yalo, kodwa lukwanobuthathaka. Ziluncedo xa udibanisa i-valve ye-PVC kwimpompo yentsimbi okanye itanki esele inemicu. Nangona kunjalo, imidibaniso yeplastiki ephothiweyo inokuba ngumthombo wokuvuza ukuba ayitywinwanga ngokufanelekileyo ngeteyiphu yeTeflon okanye uncamathisele. Okubaluleke ngakumbi, ukuqinisa ngokugqithiseleyo ukufakwa kweplastiki enemisonto yimpazamo eqhelekileyo enokuthi iqhekeze ukudibanisa kwabasetyhini, kubangele ukusilela.

Uthelekiso lweNdlela yoQhagamshelwano

Ngaba iivalvu zebhola zePVC zijonge ngakumda?

Isamente ilungile, kodwa uyathandabuza, ukhangela utolo kumzimba wevalvu. Ukuncamathelisa ivalve ngasemva kuya kuba yimpazamo enkulu, kukunyanzela ukuba uyitshabalalise.

Hayi, ivalve yebhola yePVC esemgangathweni i-bi-directional kwaye iya kuvala ukuhamba ngokulinganayo kakuhle nakweliphi na icala. Umsebenzi wayo awuxhomekeke kuqhelaniso lokuhamba. Ekuphela "kwesikhokelo" esibalulekileyo kukuyifaka ukuze ukwazi ukufikelela kwisibambo kunye namantongomane omanyano.

Lo ngumbuzo omkhulu obonisa ukucinga ngononophelo. Ulungile ukuba ulumke, njengoko ezinye iivalvu zisalathisa ngokupheleleyo. Akhangela ivalve, umzekelo, ivumela kuphela ukuhamba kwicala elinye kwaye iya kuba notolo olucacileyo olushicilelwe kuyo. Ukuba ifakwe ngasemva, ayizukusebenza. Nangona kunjalo, aivalve yebholauyilo lu-symmetrical. Inebhola enomngxuma ovala isitulo. Kuba kukho isihlalo kumacala omabini angasentla nasezantsi, ivalve ivaleka ngokugqibeleleyo nokuba yeyiphi na indlela amanzi ahamba ngayo. Ngoko ke, awukwazi ukuyifaka "ngasemva" malunga nokuhamba. Njengoko benditshilo ngaphambili, ekuphela "kwesalathiso" okufuneka ukhathazeke malunga nokuqhelaniswa okusebenzayo kokusebenzisa ivalve. Ungajika isiphatho? Ungafikelela kwiimanyano zabasebenzi? Olo luvavanyo lokwenyani lofakelo oluchanekileyo lwevalvu esemgangathweni efana nale siyivelisa ePntek.

Ukuqukumbela

Ukufakela ivalve yebhola yePVC egqibeleleyo, sebenzisa iprimer echanekileyo kunye nesamente. Cwangcisa umqheba kunye nokufikelela kwi-nut yomanyano ukuqinisekisa uqhagamshelo oluthembekileyo, lokuvuza, kunye noncedo.
