Ujongene ne-2-intshi yoqhagamshelwano lwePVC? Ubuchule obungalunganga bunokubangela ukuvuza okukhathazayo kunye nokusilela kweprojekthi. Ukufumana ilungelo elidibeneyo kwasekuqaleni kubalulekile kwinkqubo ekhuselekileyo, ehlala ihleli.
Ukuqhagamshela imibhobho emibini ye-intshi ye-PVC, sebenzisa i-2-intshi yokudibanisa i-PVC. Coca kwaye uqalise zombini iziphelo zemibhobho kunye nengaphakathi lokudibanisa, uze usebenzise i-PVC yesamente. Gcoba ngokuqinileyo umbhobho kwi-coupling kunye nekota yokujika kwaye ubambe imizuzwana engama-30.
Ndikhumbula sincokola noBudi, umanejala wokuthenga welinye lawona maqabane makhulu eIndonesia. Wanditsalela umnxeba ngenxa yokuba unokontraka omtsha awayemnike wona wayeneengxaki ezinzima
amalungu avuzayokwiprojekthi enkulu yokunkcenkceshela. Unokontraka wafunga ukuba wayelandela amanyathelo, kodwa unxibelelwano aluyi kubamba phantsi koxinzelelo. Xa sasihamba kwinkqubo yakhe, safumana iqhekeza elilahlekileyo: wayenganiki umbhobho lowoukujija kwekota yokugqibelanjengoko wayeyityhalela kwifitting. Yinkcukacha encinci, kodwa oko kujijitheka yiyona nto iqinisekisa ukuba i-samente ye-solvent isasazeka ngokulinganayo, idala i-weld epheleleyo, eyomeleleyo. Yayisisifundo esihle kwiqela lakhe ngendlela ebaluleke ngayo ubuchule obufanelekileyo. Nokuba ngezona mathiriyeli zigqwesileyo, “njani” yinto yonke.
Indlela yokudibanisa iisayizi ezimbini ezahlukeneyo zePVC?
Ngaba ufuna ukujoyina umbhobho omkhulu ukuya kwencinci? Ukufakwa okungalunganga kudala ibhotile okanye indawo ebuthathaka. Ukusebenzisa i-adapter echanekileyo kubalulekile kwinguqu egudileyo, ethembekileyo.
Ukudibanisa ubukhulu obuhlukeneyo bombhobho wePVC, kufuneka usebenzise i-bushing yokunciphisa okanye i-coupling yokunciphisa. I-bushing ingena ngaphakathi kwi-coupling standard, ngelixa i-coupling yokunciphisa idibanisa ngokuthe ngqo ubungakanani beepayipi ezimbini ezahlukeneyo. Zombini zifuna i-primer esemgangathweni kunye nendlela yesamente.
Ukukhetha phakathi kwe-ai-reducer bushingkunye aukudityaniswa kokunciphisakuxhomekeke kwimeko yakho ethile. Ukudityaniswa kwe-reducer yinto enye enokuvulwa okukhulu kwelinye icala kunye nencinci kwelinye. Kuyinto ecocekileyo, isisombululo esisodwa sokudibanisa, yithi, umbhobho we-intshi ye-2 ngqo kumbhobho we-1.5-intshi. Kwelinye icala, ai-reducer bushingyenzelwe ukuba ilingane ngaphakathi komgangatho omkhulu wokulinganisa. Ngokomzekelo, ukuba une-2-intshi yokudibanisa, unokufaka "i-2-intshi nge-1.5-intshi" i-bushing kwelinye icala. Oku kuguqula udibaniso lwakho oluqhelekileyo lwe-2-intshi lube sisinciphisi. Oku kuluncedo kakhulu ukuba sele unemilinganiselo esemgangathweni esandleni kwaye ufuna nje ukulungelelanisa uxhulumaniso olunye. Ndihlala ndicebisa uBudi ukuba abeke zombini, njengoko iikontraka zixabisa ukuba neenketho kwindawo yomsebenzi.
I-Reducer Bushing vs. I-Reducer Coupling
| Uhlobo oluFanayo | Inkcazo | Eyona meko yokusetyenziswa |

| Umnciphisi Coupling | Isifakelo esinye esineziphelo ezimbini ezinobungakanani obahlukeneyo. | Xa ufuna uxhulumaniso oluthe ngqo, elinye-iqhekeza phakathi kwemibhobho emibini. |
| Nciphisa Bushing | Isifakelo esingena ngaphakathi kodityaniso olukhulu olusemgangathweni. | Xa ufuna ukulungelelanisa indlela ekhoyo okanye ukhetha indlela yemodyuli. |
Indlela yokudibanisa iiPVC ezimbini?
Unayo imibhobho kunye nokufakelwa, kodwa awuqinisekanga kwinkqubo yokuncamathisela. Ilungu elivuzayo lingonakalisa umsebenzi wakho onzima. Ukwazi ubuchule be-welding ye-solvent efanelekileyo ayinakuxoxisana.
Ukudibanisa imibhobho emibini yePVC kubandakanya inkqubo yemichiza ebizwa ngokuba yi-solvent welding. Udinga isicoci/i-primer ukulungisa iplastiki kunye nesamente yePVC ukuze inyibilike kwaye idibanise imiphezulu kunye. Amanyathelo aphambili ngala: sika, deburr, coca, prime, isamente, kwaye uqhagamshele ngetwist.
Inkqubo yokujoyina i-PVC ichanekile, kodwa akukho nzima. Kungokulandela inyathelo ngalinye. Okokuqala, sika umbhobho wakho ngokulinganayo kangangoko usebenzisa i-PVC cutter. Ukunqunyulwa okucocekileyo kuqinisekisa ukuba umbhobho ophantsi uphume ngokugqibeleleyo ngaphakathi kwendawo efanelekileyo. Okulandelayo,deburr ngaphakathi nangaphandle komphetho osikiweyo. Naziphi na iibhula ezincinci zinokukhuhla isamente kwaye zonakalise itywina. Emva kokukhawuleza okomileyo ukukhangela imilinganiselo yakho, lixesha lelona candelo libalulekileyo. Faka isiceloiprimer emfusaukuya ngaphandle kombhobho kunye nangaphakathi kwi-fitting. Iprimer ayisosicoci nje; iqala ukuthambisa iplastiki. Musa ukuyitsiba. Landela ngoko nangoko ngebhityile, nokuba umaleko wesamente yePVC kwimiphezulu yomibini. Tyhiliza umbhobho kwi-fitting ngekota-turn twist de ime. Yibambe ngokuqinileyo imizuzwana engama-30 ukunqanda umbhobho ukuba ungaphuhli umva.
Uqikelelo lwePVC Cement Cure Times
Ixesha lokunyanga libalulekile. Musa ukuvavanya umdibaniso ngoxinzelelo de i-samente ibe nzima ngokupheleleyo. Eli xesha liyahluka ngobushushu.
| Uluhlu lobushushu | Ixesha lokuqala elimisiweyo (Isiphatho) | Ixesha elipheleleyo lokunyanga (uxinzelelo) |
|---|---|---|
| 60°F – 100°F (15°C – 38°C) | 10 - 15 imizuzu | 1 - 2 iiyure |

Obuphi ubungakanani ukudityaniswa 2 intshi PVC?
Unombhobho wePVC we-intshi ezi-2, kodwa yeyiphi imilinganiselo efanelekileyo? Ukuthenga indawo engalunganga kuchitha ixesha kunye nemali. Ingqungquthela yokulinganisa yofakelo lwePVC ilula xa uwazi umthetho.
Kuba umbhobho PVC 2-intshi, kufuneka 2-intshi PVC ukudibanisa. Ufakelo lwePVC luthiywe ngokusekwe kubungakanani bombhobho oqhelekileyo abaqhagamsheleka kuwo. Idayamitha yangaphandle yombhobho inkulu kune-intshi ezi-2, kodwa uhlala uthelekisa umbhobho we-"intshi ezi-2" kunye nokufakwa kwe-"intshi ezi-2".
Le yenye yezona ngongoma zixhaphakileyo zokubhideka ndinceda abathengisi abatsha bakaBudi baqonde. Banabathengi abalinganisa umphandle wombhobho wabo we-intshi ezi-2, bafumanisa ukuba iphantse ibe yi-2.4 intshi, baze bajonge into ehambelanayo nomlinganiselo. Yimpazamo esengqiqweni, kodwa ayisiyiyo indlela iPVC esebenza ngayo. Ileyibhile "2-intshi" ligama lezorhwebo, elaziwa ngokuba yiUbungakanani bombhobho oqhelekileyo (NPS). Ngumgangatho oqinisekisa nawuphi na umenzi we-2-intshi umbhobho uya kufaneleka nawuphi na umenzi we-2-intshi efanelekileyo. Njengomvelisi, sakha izifakelo zethu kwezi zichanekileyoImigangatho ye-ASTM. Oku kuqinisekisa ukusebenzisana kwaye kwenza izinto zibe lula kumsebenzisi-siphelo: thelekisa nje ubungakanani begama. Musa ukuzisa irula kwivenkile yehardware; khangela nje inombolo eprintiweyo kumbhobho kwaye uthenge ukulinganisa ngenani elifanayo.
Ubungakanani bombhobho oqhelekileyo vs. Oyena Mda woMda waNgaphandle
| Ubungakanani bombhobho oqhelekileyo (NPS) | Okwenziweyo Ububanzi boMphandle (malunga.) |
|---|---|
| 1/2 intshi | 0.840 intshi |
| 1 intshi | 1.315 intshi |
| 1-1/2 intshi | 1.900 intshi |
| 2 intshi | 2.375 intshi |
Ukuqukumbela
Ukudibanisa i-intshi ye-PVC eyi-2 kulula kunye nokudibanisa i-intshi ezi-2 kunye ne-welding efanelekileyo ye-solvent. Ngobukhulu obahlukeneyo okanye imathiriyeli, soloko usebenzisa isinciphisi esichanekileyo okanye iadaptha yomsebenzi ongavuziyo.
