Ngaba ujongene noqhagamshelo lwe-PVC oluzii-intshi ezi-2? Indlela engalunganga inokubangela ukuvuza okubangela ukudideka kunye nokungaphumeleli kweprojekthi. Ukudibanisa i-joint kwasekuqaleni kubalulekile kwinkqubo ekhuselekileyo nehlala ixesha elide.

Ukuze udibanise imibhobho emibini ye-PVC eyi-intshi ezimbini, sebenzisa i-PVC coupling eyi-intshi ezimbini. Coca kwaye ucofe zombini iziphelo zemibhobho kunye nangaphakathi kwe-coupling, uze ufake isamente ye-PVC. Tyhala umbhobho ngokuqinileyo kwi-coupling ngokujika ikota uze ubambe imizuzwana engama-30.

Ndikhumbula ndithetha noBudi, umphathi wokuthenga omnye wamaqabane ethu amakhulu eIndonesia. Wanditsalela umnxeba kuba inkampani entsha awayeyinikezile yayineengxaki ezinkulu ngayo.
amalungu avuzayokwiprojekthi enkulu yokunkcenkceshela. Umenzi-kontrakta wafunga ukuba uyalandela amanyathelo, kodwa uqhagamshelo aluyi kubambelela phantsi koxinzelelo. Xa sihamba kwinkqubo yakhe, safumana into engekhoyo: wayenganiki mbhobho lowoinguqu yokugqibela yekotanjengoko wayeyityhala kwindawo yokufakela. Yinto encinci kakhulu, kodwa loo nto yiyo eqinisekisa ukuba isamente yesinyibilikisi isasazeka ngokulinganayo, idala i-weld epheleleyo neyomeleleyo. Yayisisifundo esihle kwiqela lakhe malunga nokuba ubuchule obufanelekileyo bubaluleke kangakanani. Nokuba kukho izixhobo ezilungileyo, "indlela" yinto yonke.

Ungadibanisa njani ubungakanani obuhlukeneyo bePVC?

Ngaba ufuna ukuhlanganisa umbhobho omkhulu nomncinci? Ukufakelwa okungalunganga kudala ingxaki okanye indawo ebuthathaka. Ukusebenzisa i-adaptha efanelekileyo kubalulekile ukuze kubekho utshintsho oluthambileyo noluthembekileyo.

Ukuze udibanise ubungakanani obahlukeneyo bombhobho wePVC, kufuneka usebenzise i-reducer bushing okanye i-reducer coupling. I-bushing ingena ngaphakathi kwi-standard coupling, ngelixa i-reducer coupling idibanisa ngokuthe ngqo ubungakanani obubini obahlukeneyo bombhobho. Zombini zifuna indlela ye-primer eqhelekileyo kunye nesamente.

Ukukhetha phakathii-reducer bushingkunyeukudibanisa okunciphisiweyokuxhomekeke kwimeko yakho ethile. I-reducer coupling yinto enye enendawo enkulu kwelinye icala kunye nencinci kwelinye. Sisisombululo esicocekileyo nesincinci sokudibanisa, masithi, umbhobho we-intshi ezi-2 ngqo kumbhobho we-intshi eziyi-1.5. Kwelinye icala,i-reducer bushingYenzelwe ukulingana ngaphakathi kwesixhobo esikhulu esiqhelekileyo. Umzekelo, ukuba unesixhobo sokudibanisa esiziisentimitha ezi-2, ungafaka i-bushing "yeesentimitha ezi-2 nge-1.5" kwicala elinye. Oku kuguqula isixhobo sakho sokudibanisa esiziisentimitha ezi-2 sibe sisixhobo sokunciphisa. Oku kuluncedo kakhulu ukuba sele unezixhobo ezisemgangathweni ezikhoyo kwaye kufuneka nje uhlengahlengise uqhagamshelo olunye. Ndisoloko ndicebisa uBudi ukuba agcine zombini, njengoko abakhi bezindlu beyawuxabisa amathuba okuba neendawo zomsebenzi.

Ungazidibanisa njani iiPVC ezimbini?

Unayo imibhobho kunye nezinto zokufakela, kodwa awuqinisekanga ngenkqubo yokuncamathisela. Ijoyinti evuzayo inokonakalisa umsebenzi wakho onzima. Ukwazi indlela efanelekileyo yokuwelda isinyibilikisi akunakuxoxiswana ngayo.

Ukudibanisa imibhobho emibini yePVC kubandakanya inkqubo yeekhemikhali ebizwa ngokuba yi-solvent welding. Udinga isicoci/i-primer ukulungiselela iplastiki kunye nesamente yePVC ukuze zinyibilike kwaye zidibanise umphezulu. Amanyathelo aphambili ngala: ukusika, ukususa i-burr, ukucoca, ukuphakamisa, isamente, kunye nokudibanisa nge-twist.

Inkqubo yokudibanisa i-PVC ichanekile, kodwa ayinzima. Imalunga nokulandela inyathelo ngalinye. Okokuqala, sika umbhobho wakho ngokuchanekileyo kangangoko usebenzisa isixhobo sokusika i-PVC. Ukusika okucocekileyo kuqinisekisa ukuba amazantsi ombhobho aphuma ngokugqibeleleyo ngaphakathi kwesixhobo sokudibanisa. Okulandelayo,susa umphetho ongaphakathi nongaphandle komphetho osikiweyoNaziphi na iibher ezincinci zingasusa isamente kwaye zonakalise isitywino. Emva kokufaka ngokukhawuleza ukuze ujonge ubungakanani bakho, lixesha lokuba ufake indawo ebalulekileyo. Fakaiprimer emfusaukuya ngaphandle kombhobho nangaphakathi kwesixhobo sokufaka. I-Primer ayisiyonto yokucoca nje kuphela; iqala ukuthambisa iplastiki. Musa ukuyitsiba. Landela ngoko nangoko ngomaleko omncinci, olinganayo wesamente ye-PVC kwiindawo zombini. Tyhala umbhobho kwisixhobo sokufaka ngokujika ikota ide ime. Yibambe ngokuqinileyo imizuzwana engama-30 ukuthintela umbhobho ukuba ungatyhaleli ngaphandle.

Amaxesha Aqikelelweyo Onyango Lwesamente yePVC

Ixesha lokunyanga libalulekile. Musa ukuvavanya ijoyinti ngoxinzelelo ide isamente iqine ngokupheleleyo. Eli xesha liyahluka ngokweqondo lobushushu.

Indlela yokudibanisa imibhobho emibini yobubanzi obahlukeneyo?

Ukudibanisa imibhobho yobukhulu obahlukeneyo kubonakala kunzima. Ukudibanisa okungekho semgangathweni kunokubangela ukuvuza okanye ukuthintela ukuhamba kwamanzi. Ukusebenzisa ukufakelwa okufanelekileyo kwenza utshintsho lube lula, luqine, kwaye lusebenze kakuhle kuyo nayiphi na inkqubo.

Ukuze uqhagamshele imibhobho enobubanzi obahlukeneyo, sebenzisa isixhobo esithile sokutshintsha esifana ne-reducer coupling. Kwizinto ezahlukeneyo, ezifana ne-PVC ukuya kwi-copper, udinga i-adaptha ekhethekileyo, efana ne-I-adaptha yamadoda ye-PVC eqhagamshelwe kwisixhobo sobhedu esinomgca sabasetyhini.

Ukudibanisa imibhobho kumalunga nokuba "nebhulorho" efanelekileyo phakathi kwayo. Ukuba uhlala usebenzisa izinto ezifanayo, njengePVC, i-reducer coupling yeyona bhulorho ingqamene ngqo phakathi kweedayamitha ezimbini ezahlukeneyo. Kodwa kuthekani ukuba ufuna ukudibanisa iPVC kumbhobho wesinyithi? Kulapho ke ufuna uhlobo olwahlukileyo lwebhulorho:
iiadaptha ezinemisonto. Ubungayitshixa i-adapter ye-PVC ngemisonto yesilisa okanye yesifazane kumbhobho wakho we-PVC. Oku kukunika isiphelo esinemisonto onokusidibanisa nesixhobo sesinyithi esifanelekileyo. Lulwimi oluqhelekileyo lokudibanisa izinto ezahlukeneyo zemibhobho. Isitshixo kukuba ungaze uzame ukuncamathisela i-PVC ngqo kwisinyithi. Ayizukusebenza. Uqhagamshelo olunemisonto yeyona ndlela ikhuselekileyo. Xa usenza olu qhagamshelo, sebenzisa rhoqoIteyiphu yePTFE (iteyiphu yeTeflon)kwimisonto yendoda ukunceda ukuvala ilungu kunye nokuthintela ukuvuza.

Izisombululo zoLungiso oluQhelekileyo

Yeyiphi i-coupling yobukhulu be-2 intshi ye-PVC?

Unombhobho we-PVC ozii-intshi ezi-2, kodwa loluphi uhlobo lokufakela oluchanekileyo? Ukuthenga indawo engafanelekanga kuchitha ixesha nemali. Indlela yokulinganisa ubungakanani bezixhobo ze-PVC ilula xa sele uwazi umthetho.

Kwipayipi yePVC eyi-intshi ezi-2, udinga i-PVC coupling eyi-intshi ezi-2. Izixhobo zePVC zibizwa ngokusekwe kubungakanani bepayipi eziqhagamshelwa kuyo. Ububanzi bangaphandle bepayipi bukhulu kune-intshi ezi-2, kodwa uhlala ufanisa ipayipi "ye-intshi ezi-2" kunye ne-"intshi ezi-2".

Le yenye yezona ngongoma zixhaphakileyo endinceda abathengisi abatsha baseBudi ukuba baziqonde. Banabathengi abalinganisa umphandle wombhobho wabo oyi-intshi ezimbini, bafumanise ukuba uphantse ube yi-intshi eziyi-2.4, baze bajonge into ehambelana nomlinganiselo. Yimpazamo enengqondo, kodwa asikuko indlela esebenza ngayo ubungakanani bePVC. Ileyibhile "ye-intshi ezimbini" ligama lorhwebo, elaziwa ngokuba yiUbungakanani bePayipi eNominal (NPS)Yindlela esemgangathweni eqinisekisa ukuba umbhobho we-2-intshi womenzi uya kufaneleka nakweyiphi na i-2-intshi yomenzi. Njengomenzi, sakha izixhobo zethu ngokwezi zichanekileyo.Imigangatho ye-ASTMOku kuqinisekisa ukusebenzisana kwaye kwenza izinto zibe lula kumsebenzisi wokugqibela: fanisa ubungakanani obuqhelekileyo. Musa ukuzisa irula evenkileni yezixhobo zentsimbi; khangela nje inombolo eprintiweyo kumbhobho uze uthenge i-fitting enenombolo efanayo.

Isiphelo

Ukudibanisa i-PVC ye-intshi ezi-2 kulula nge-coupling ye-intshi ezi-2 kunye ne-solvent welding efanelekileyo. Kwiisayizi okanye izinto ezahlukeneyo, soloko usebenzisa i-reducer fitting okanye i-adapter efanelekileyo ukuze ukhuseleke ekuvuzeni.
