Ujonge umbhobho, kwaye kukho isiphatho esiphumayo. Kufuneka ulawule ukuhamba kwamanzi, kodwa ukwenza ngaphandle kokwazi ngokuqinisekileyo kunokukhokelela ekuvuzeni, ekonakaleni, okanye ekuziphatheni okungalindelekanga kwenkqubo.

Ukusebenzisa umgangathoIvalvu yebhola yePVC, jika isiphatho ngekota-turn (90 degrees). Xa isiphatho sihambelana nombhobho, ivalvu ivulekile. Xa isiphatho sithe nkqo kumbhobho, ivalvu ivaliwe.

Oku kungabonakala kulula, kodwa lolona lwazi lubalulekileyo kuye nabani na osebenza ngemibhobho. Ndisoloko ndixelela iqabane lam, uBudi, ukuba ukuqinisekisa ukuba iqela lakhe lokuthengisa liyakwazi ukuchaza ngokucacileyo ezi ziseko kubakhi abatsha okanye abathengi be-DIY yindlela elula yokwakha ukuthembana. Xa umthengi eziva eqinisekile ngemveliso, nokuba incinci kangakanani, kunokwenzeka ukuba amthembe umsasazi owamfundisayo. Linyathelo lokuqala kwintsebenziswano ephumelelayo.

Isebenza njani ivalvu yePVC?

Uyazi ukuba ukujika isiphatho kuyasebenza, kodwa awazi ukuba kutheni. Oku kwenza kube nzima ukuchaza ixabiso laso ngaphandle kokuba siswitshi sokuvula/sokucima okanye ukusombulula ingxaki ukuba kukho into engahambanga kakuhle.

Ivalvu yebhola yePVC isebenza ngokujikeleza ibhola elingqukuva elinomngxuma odlula kuyo. Xa ujika isiphatho, umngxuma uhambelana nombhobho ukuze uphume (uvuleke) okanye ujike uvale umbhobho (uvaliwe).

Ingqondo yobukrelekreleivalvu yebholabubulula bayo kunye nokusebenza kwayo kakuhle. Xa ndibonisa iqela likaBudi isampulu, ndisoloko ndibonisa iindawo ezibalulekileyo. Ngaphakathi kwivalvuumzimba, kukho iibholaenomngxuma, owaziwa ngokuba yi-port. Le bhola ihleli kakuhle phakathi kwezitywina ezimbini eziqinileyo, esizenzayo kwaPntekI-PTFEixesha elide. Ibhola iqhagamshelwe kwi-outerphathangeposi ebizwa ngokuba yiisiqu. Xa ujika isiphatho ngama-90 degrees, isiqu siyayijikeleza ibhola. Le ntshukumo yokujika ikota yeyona nto yenza iivalvu zebhola zikhawuleze kwaye zibe lula ukuzisebenzisa. Luyilo olulula, oluqinileyo olubonelela ngokuvala okupheleleyo nokuthembekileyo kunye neendawo ezimbalwa ezishukumayo, yiyo loo nto iyindlela eqhelekileyo yeenkqubo zolawulo lwamanzi kwihlabathi liphela.

Ungazi njani ukuba ivalvu yePVC ivuliwe okanye ivaliwe?

Usondela kwivalvu kwinkqubo yemibhobho entsonkothileyo. Awunakuqiniseka ukuba ivumela amanzi ukuba angene okanye hayi, kwaye ukuqikelela okungalunganga kunokuthetha ukutshizwa okanye ukuvala umgca ongalunganga.

Jonga indawo yesiphatho xa kuthelekiswa nombhobho. Ukuba isiphatho sihambelana (sihamba kwicala elifanayo nombhobho), ivalvu ivulekile. Ukuba sithe nkqo (senza imilo "T"), sivaliwe.

Lo mthetho obonakalayo ngumgangatho weshishini ngesizathu: ucacile kwaye awushiyi ndawo yamathandabuzo. Indlela yesiphatho ifana ngokoqobo nemeko yezibuko ngaphakathi kwevalvu. Ndisoloko ndixelela uBudi ukuba iqela lakhe lifanele ligxininise lo mthetho ulula—“Into ehambelanayo ithetha iPass, iPerpendicular ithetha iPlugged.” Olu ncedo luncinci lokukhumbula lunokuthintela iimpazamo ezibizayo kubalimi begadi, iingcali zedama lokubhukuda, kunye namaqela olondolozo lwemizi-mveliso ngokufanayo. Luphawu lokhuseleko olwakhelwe ngqo kuyilo. Ukuba ubona isiphatho sevalvu kwi-engile ye-45-degree, kuthetha ukuba ivalvu ivulekile kancinci, ngamanye amaxesha enokusetyenziswa ekuthomalaliseni ukuhamba kwamanzi, kodwa uyilo lwayo oluphambili lolweendawo ezivulekileyo ngokupheleleyo okanye ezivaliweyo ngokupheleleyo. Ukuze uvale kakuhle, soloko uqinisekisa ukuba imile nkqo ngokupheleleyo.

Ungayiqhagamshela njani ivalvu kumbhobho wePVC?

Unayo ivalvu nombhobho wakho, kodwa ukufumana isitywino esikhuselekileyo nesingenako ukuvuza kubalulekile. Ilungu elinye elibi linokuphazamisa ukuthembeka kwenkqubo yonke, nto leyo ekhokelela ekungasebenzi kakuhle nasekuphindeni kusetyenziswe imali eninzi.

Kwivalvu yokuwelda yesolvent, faka i-primer yePVC, uze ufake isamente kwisiphelo sepayipi nakwisokhethi yevalvu. Zityhale kunye uze ujike ngekota. Kwiivalvu ezinemisonto, songa imisonto ngeteyipu yePTFE ngaphambi kokuba uyiqinise.

Ukudibanisa ngendlela eyiyo akunakuxoxiswana ngako ukuze kubekho inkqubo ethembekileyo. Le yindawo apho izixhobo ezisemgangathweni kunye nenkqubo echanekileyo zizinto ezibalulekileyo. Ndicebisa iqela likaBudi ukuba lifundise abathengi balo ezi ndlela zimbini:

1. Ukuwelda kweSoluli (kwiivalufa zeSokhethi)

Le yeyona ndlela ixhaphakileyo. Idala umanyano oluhlala luhleli noludibeneyo.

1. Lungiselela:Yenza isikwele esicocekileyo nesilinganayo kumbhobho wakho uze ususe naziphi na iziqwenga.
2. Inkulu:Faka iprimer yePVC ngaphandle kombhobho nangaphakathi kwesokethi yevalvu. Iprimer ihlambulula umphezulu ize iqalise ukuthambisa iPVC.
3. Isamente:Faka ngokukhawuleza umaleko wesamente yePVC kwiindawo ezilungisiweyo.
4. Qhagamshela:Yityhale ngoko nangoko ipayipi kwisokethi yevalvu uze uyijike ikota ukuze isabalalise isamente ngokulinganayo. Yibambe imizuzwana engama-30 ukuze uthintele ukuba ipayipi ingaphumi.

2. Uqhagamshelo olunemisonto (lweeValve ezinemisonto)

Oku kuvumela ukuqhaqhwa, kodwa ukutywinwa kubalulekile.

1. Iteyiphu:Songa iteyiphu yePTFE (iteyiphu yeTeflon) izihlandlo ezi-3-4 ujikeleze imisonto yesilisa kwicala elijikajikayo.
2. Qinisa:Yijije ivalvu ngesandla, uze usebenzise isikrufu kwenye indawo enye ukuya kweyesibini. Musa ukuyiqinisa kakhulu, kuba ungayiqhekeza iPVC.

Ungayijonga njani ukuba ivalvu yePCV iyasebenza?

Ucinga ukuba ivalvu ayisebenzi, nto leyo ebangela iingxaki ezifana noxinzelelo oluphantsi okanye ukuvuza. Uva ngokukhangela "ivalvu yePCV" kodwa awuqinisekanga ukuba oko kusebenza njani kumbhobho wakho wamanzi.

Okokuqala, cacisa eli gama. Uthetha ivalvu yePVC (yeplastiki), hayi ivalvu yePCV yenjini yemoto. Ukujonga ivalvu yePVC, jika isiphatho. Ifanele ihambe kakuhle ngama-90° kwaye iyeke ngokupheleleyo ukuhamba xa ivaliwe.

Lo ngumahluko obaluleke kakhulu endiqinisekisa ukuba iqela likaBudi liyawuqonda. I-PCV imele i-Positive Crankcase Ventilation kwaye yinxalenye yokulawula ukukhutshwa komoya emotweni. I-PVC imele i-Polyvinyl Chloride, iplastiki eyenziwe ngayo iivalvu zethu. Umthengi uyazixuba ziqhelekile.

Nantsi uluhlu olulula lokujonga ukubaivalvu yePVCisebenza ngokuchanekileyo:

1. Jonga isiphatho:Ingaba ijika ibe ngama-90 degrees apheleleyo? Ukuba iqinile kakhulu, izitywini zisenokuba zindala. Ukuba ikhululekile okanye ijikeleza ngokukhululekileyo, isiqu esingaphakathi sisenokuba siphukile.
2. Hlola ukuvuza:Khangela amathontsi avela emzimbeni wevalvu okanye apho isiqu singena khona kwisibambo. KwaPntek, indibano yethu ezenzekelayo kunye novavanyo loxinzelelo kunciphisa le mingcipheko kwasekuqaleni.
3. Vavanya i-Cloff:Vala ivalvu ngokupheleleyo (isiphatho sime nkqo). Ukuba amanzi asangena emgceni, ibhola yangaphakathi okanye izitywini zonakele, kwaye ivalvu ayisakwazi ukuvala kakuhle. Kufuneka itshintshwe.

Isiphelo

Ukusebenzisaivalvu yePVCilula: isiphatho esihambelanayo sithetha ukuba sivulekile, sithe nkqo sivaliwe. Ufakelo olufanelekileyo lwe-solvent-weld okanye olunemisonto kunye nokuhlolwa kokusebenza
