Usuqedile, kodwa uphawu oluvuzayo lusho ukuchitha isikhathi, imali, nezinto zokwakha. Ijoyinti elilodwa elibi emugqeni we-PVC lingaphoqa ukuthi usike ingxenye yonke bese uqala phansi.

Ukuze ufake i-ball valve epayipini le-PVC, usebenzisa i-solvent welding. Lokhu kuhilela ukusika ipayipi kahle, ukususa uthuli, ukufaka i-primer ye-PVC kanye ne-samente kuzo zombili izindawo, bese uzicindezela ndawonye nge-quarter twist bese uzibamba ngokuqinile kuze kube yilapho isibopho samakhemikhali siqina.

Lokhu akukhona nje ukunamathelisa; kuyinqubo yamakhemikhali ehlanganisa ipulasitiki ibe yingcezu eyodwa eqinile. Ukukwenza kahle akunakuxoxiswana ngakho kochwepheshe. Yiphuzu engihlala ngigcizelela kubalingani abanjengoBudi e-Indonesia. Amakhasimende akhe, kungakhathaliseki ukuthi angamakhontrakthi amakhulu noma abathengisi bendawo, ancike ekuthembekeni. I-joint ehlulekile akuyona nje into evuzayo; kuyiphutha lephrojekthi futhi iyisikhubekiso edumeleni labo. Ake sixoxe ngemibuzo ebalulekile ukuze senze ukufakwa ngakunye kube yimpumelelo.

Uxhuma kanjani i-valve epayipini le-PVC?

Une-valve esandleni, kodwa ubheke ipayipi elibushelelezi. Uyazi ukuthi kunezinhlobo ezahlukene zokuxhuma, kodwa iyiphi efanele umsebenzi wakho ukuqinisekisa uhlelo oluqinile, olungavuzi?

Uxhuma i-valve epayipini le-PVC ngenye yezindlela ezimbili: uxhumano oluhlala njalo lwe-solvent-weld (isokhethi), olungcono kakhulu kwi-PVC-kuya-PVC, noma uxhumano olunentambo olulungisekayo, olufanele ukuhlanganisa i-PVC nezingxenye zensimbi ezifana namaphampu.

Ukukhetha indlela efanele kuyisinyathelo sokuqala sokufakwa kochwepheshe. Kumasistimu asebenza nge-PVC ngokuphelele,ukushisela i-solventkuyindinganiso yemboni. Kwakha ijoyinti elingenamthungo, elihlanganisiwe eliqinile njengepayipi uqobo. Inqubo iyashesha, ithembekile, futhi ihlala njalo. Ukuxhumeka okunezintambo kusetshenziswa uma udinga ukuxhuma umugqa wakho we-PVC kokuthile ngezintambo zensimbi ezikhona, noma uma ulindele ukuthi udinga ukususa ivalvu kalula kamuva. Kodwa-ke, ukufakwa kwepulasitiki okunezintambo kumele kufakwe ngokucophelela ukuze kugwenywe ukuqhekeka ekuqineni ngokweqile. Kumapayipi amaningi e-PVC ajwayelekile, ngihlala ngincoma amandla kanye nobulula bokuxhumeka kwe-solvent-weld. Uma ukuseviswa kubalulekile,i-valve yebhola yomanyano weqinisoikunikeza okuhle kakhulu kokubili.

Iyiphi indlela efanele yokufaka i-ball valve?

Ivalvu inamathele kahle, kodwa manje isibambo sishaya udonga futhi asikwazi ukuvala. Noma ufake ivalvu yokuhlanganisa eqinile kakhulu endololwaneni kangangokuthi awukwazi ukufaka isikrufu kuyo.

"Indlela efanele" yokufaka ivalvu yebhola ukuhlela ukusebenza kwayo. Lokhu kusho ukuthi kufanele ifakelwe okomile kuqala ukuqinisekisa ukuthi isibambo sinendawo yokujika engu-90 degrees kanye nokuthi ama-union nuts ayatholakala ngokuphelele ukuze agcinwe isikhathi esizayo.

Ukufakwa okuphumelelayo kudlulela ngale nje kwe-uphawu olungavuzi; kumayelana nokusebenza kwesikhathi eside. Yilapho umzuzu wokuhlela usindisa khona ihora lokusebenza kabusha. Ngaphambi kokuthi uvule i-primer, beka i-valve endaweni yayo ehlosiwe bese ushwiba isibambo. Ingabe ihamba ngokukhululeka kusukela ekuvulekeni ngokuphelele kuya ekuvalekeni ngokuphelele? Uma kungenjalo, udinga ukulungisa ukuma kwayo. Okwesibili, uma usebenzisa ikhwalithi ephezului-valve yomanyano yangempelaNjengathi ePntek, kufanele uqinisekise ukuthi uyakwazi ukufinyelela ama-union nuts. Inhloso yala ma-valve ukuvumela ukususwa komzimba we-valve ngaphandle kokunquma ipayipi. Ngihlala ngikhumbuza uBudi ukuthi atshele amakhasimende akhe lokhu: uma ungakwazi ukufaka isikrufu kuma-nuts, usuyinqobile yonke injongo ye-valve. Cabanga ngakho njengokufaka hhayi nje kwanamuhla, kodwa nakumuntu okumele ayilungise eminyakeni emihlanu kusukela manje.

Ingabe ama-valve ebhola e-PVC aqonde ngqo?

Usulungele ukusimende, kodwa uyama, ubheka umcibisholo ogelezayo emzimbeni wevalvu. Uyazi ukuthi ukunamathisela ivalvu eqondisa emuva kungaba yiphutha elibi kakhulu nelibizayo.

Cha, ivalvu yebhola ye-PVC ejwayelekile ayiqondi; iqondisa kabili. Isebenzisa umklamo olinganayo onezivalo ezinhlangothini zombili, okuvumela ukuthi uvale ukugeleza ngokulinganayo kusuka kunoma iyiphi indlela. "Indlela" okuwukuphela kwayo okufanele ukhathazeke ngayo ukuqondiswa kwayo ngokomzimba kokufinyelela kwezibambo.

Lona umbuzo omuhle kakhulu futhi ovamile. Isexwayiso sakho sifanelekile ngoba amanye ama-valve, njengeama-valve okuhlolanoma ama-globe valve, aqonde ngqo futhi azohluleka uma efakwe emuva. Anomcibisholo ohlukile emzimbeni ukuze akuqondise.ivalvu yebholaNokho, isebenza ngendlela ehlukile. Ingaphakathi layo liyibhola elilula elinembobo kulo, elijikeleza ukuze livalwe esihlalweni. Njengoba kunesihlalo ohlangothini oluphezulu nolungezansi lwebhola, lidala ukuvala okuqinile kungakhathaliseki ukuthi ingcindezi ivela ngakuphi. Ngakho-ke, ungaphumula. Awukwazi ukufaka ivalvu yebhola ejwayelekile "ebuyela emuva" maqondana nokugeleza. Lo mklamo olula noqinile ungenye yezizathu zokuthandwa kangaka. Mane ugxile ekulibekeni ukuze kube lula ukufinyelela isibambo kanye nama-union.

Ama-valve ebhola e-PVC athembeke kangakanani?

Ubone ivalvu ye-PVC eshibhile, engabizwa ngegama, iqhekeka noma ivuza ngemva konyaka owodwa kuphela, okwenza uzibuze ngezinto zokwakha. Uzibuza ukuthi kufanele yini usebenzise ivalvu yensimbi ebiza kakhulu.

Amavalvu ebhola e-PVC asezingeni eliphezulu athembeke kakhulu futhi angahlala amashumi eminyaka. Isikhathi sawo sokuphila sinqunywa yikhwalithi yezinto zokusetshenziswa (i-virgin vs. i-PVC esetshenzisiwe), ukunemba kokukhiqiza, kanye nokufakwa okufanele. Ivalvu esezingeni eliphezulu ivame ukuhlala isikhathi eside kunesistimu ekuyo.

Ukuthembeka kwe-I-valve yebhola ye-PVCkuncike ekutheni yenziwe ngani nokuthi yenziwe kanjani. Lokhu kuyingqikithi yefilosofi yethu kwa-Pntek.

Yini Enquma Ukuthembeka?

• Ikhwalithi Yezinto Ezibalulekile:Siphikelela ekusebenziseniI-PVC engu-100% emsulwaAma-valve amaningi ashibhile asebenzisa izinto eziphinde zasetshenziswa noma zokugcwalisa, okwenza ipulasitiki ibe buthakathaka futhi ithambekele ekuhlulekeni ngaphansi kwengcindezi noma ukuchayeka ku-UV. I-Virgin PVC inikeza amandla aphezulu kanye nokumelana namakhemikhali.
• Ukunemba Kokukhiqiza:Ukukhiqizwa kwethu okuzenzakalelayo kuqinisekisa ukuthi yonke ivalvu iyafana. Ibhola kumele libe yindilinga ngokuphelele futhi izihlalo zibe bushelelezi ngokuphelele ukuze kwakheke uphawu oluqinile njengebhamuza. Sihlola amavalvu ethu ngengcindezi ukuze afinyelele ezingeni eliphakeme kakhulu kunalelo abazolibona ensimini.
• Umklamo Wokuphila Isikhathi Eside:Izici ezifana nomzimba wobumbano wangempela, ama-EPDM noma ama-FKM O-rings, kanye nomklamo wesiqu oqinile konke kunegalelo empilweni yenkonzo ende. Lona umehluko phakathi kwengxenye elahliwe kanye nempahla yesikhathi eside.

Ivalvu ye-PVC eyenziwe kahle, efakwe kahle ayiyona isixhumanisi esibuthakathaka; iyisisombululo esiqinile, esingagqwali, futhi esingabizi kakhulu.
