Ukukhetha phakathi kwe-CPVC ne-PVC kungenza noma kuphule isistimu yakho yokufaka amapayipi. Ukusebenzisa izinto ezingalungile kungaholela ekuhlulekeni, ekuvuzeni, noma ngisho nasekuqhumeni okuyingozi ngaphansi kwengcindezi.

Umehluko omkhulu ukubekezelela izinga lokushisa - i-CPVC iphatha amanzi ashisayo afika ku-93 ° C (200 ° F) kuyilapho i-PVC ilinganiselwe ku-60 ° C (140 ° F). Amavalvu e-CPVC nawo ayabiza kancane futhi anokumelana namakhemikhali kangcono ngenxa yesakhiwo sawo esine-chlorine.

Uma uwabuka nje, la mavalvu epulasitiki abukeka acishe afane. Kodwa umehluko wabo wamangqamuzana udala izikhala ezibalulekile zokusebenza okufanele wonke umklami nomfakisi aziqonde. Emsebenzini wami namakhasimende amaningi afana noJacky, lo mehluko uvame ukuvela lapho ngisebenzelana nezicelo zamanzi ashisayo lapho okujwayelekile.I-PVCizohluleka. I-chlorine eyengeziwe ngaphakathiI-CPVCiyinikeza izakhiwo ezithuthukisiwe ezithethelela intengo yayo ephezulu ezimweni ezithile, kuyilapho i-PVC evamile ihlala iyinketho engokongayo yezinhlelo zamanzi ezijwayelekile.

Kwenzekani uma usebenzisa i-PVC esikhundleni se-CPVC?

Umzuzwana wokonga izindleko ungaholela ekuhlulekeni okuyinhlekelele. Ukukhetha i-PVC lapho i-CPVC idingeka khona kuyingozi ekubhidlikeni, ukuqhekeka, nokulahlekelwa kwengcindezi eyingozi kumasistimu ashisayo.

Ukusebenzisa i-PVC emanzini ashisayo (ngaphezulu kuka-60°C/140°F) kuzobangela ukuba ipulasitiki ithambe futhi yonakale, okuholela ekuvuzeni noma ekuhlulekeni ngokuphelele. Ezimweni ezimbi kakhulu, i-valve ingaqhuma ekucindezelweni lapho yenziwe buthaka ukushisa, okungase kubangele ukulimala kwamanzi kanye nezingozi zokuphepha.

Ngikhumbula icala lapho iklayenti likaJacky lafaka khona amavalvu e-PVC kusistimu yomshini wokuwasha izitsha ukuze konge imali. Phakathi namasonto ambalwa, ama-valve aqala ukugoqa nokuvuza. Izindleko zokulungisa zidlule kude noma yikuphi ukongiwa kokuqala. Isakhiwo samangqamuzana e-PVC asikwazi ukumelana namazinga okushisa aqhubekayo - amaketanga epulasitiki aqala ukuphuka. Ngokungafani namapayipi ensimbi, lokhu kuthambisa akubonakali kuze kube yilapho kwenzeka ukwehluleka. Yingakho amakhodi wokwakha elawula ngokuqinile lapho impahla ngayinye ingasetshenziswa khona.

Yiziphi izinzuzo ze-valve yebhola ye-PVC?

Yonke iphrojekthi ibhekene nezingcindezi zesabelomali, kodwa awukwazi ukuyekethisa ekuthembekeni. Ama-valve e-PVC ashaya ibhalansi ephelele lapho izimo zivuma.

Amavalvu e-PVC anikeza ukusebenza kahle kwezindleko okungenakuhlulwa, ukufakwa kalula, nokumelana nokugqwala okuphakeme uma kuqhathaniswa nezinye izindlela zensimbi. Ashibhe ngo-50-70% kune-CPVC kuyilapho enikeza ukusebenza okuhle kakhulu emanzini abandayo.

Kuzinhlelo zamanzi abandayo, alikho inani elingcono kune-PVC. Ukuxhumana kwabo kwe-solvent-weld kudala amalunga asheshayo, anokwethenjelwa kunokufakwa kwensimbi okufakwe imicu, okunciphisa izindleko zabasebenzi. Ngokungafani nensimbi, azilokothi zigqwale noma zakhe amadiphozithi amaminerali. E-Pntek, senze unjiniyela wethuAma-valve e-PVCenemizimba eqinisiwe egcina ubuqotho bayo ngisho nangemva kwamashumi eminyaka yokusetshenziswa. Okwamaphrojekthi afana noJackyizinhlelo zokuchelela zezolimolapho izinga lokushisa lingeyona into ekhathazayo, i-PVC ihlala iyisinqumo esihlakaniphe kakhulu.

Kungani i-CPVC ingasasetshenziswa?

Ungase uzwe izimangalo zokuthi i-CPVC isiphelelwa yisikhathi, kodwa iqiniso liyahlukahluka kakhulu. Intuthuko yezinto ezibonakalayo ayizange isuse izinzuzo zayo eziyingqayizivele.

I-CPVC isasetshenziswa kabanzi kodwa ithathelwe indawo yi-PEX nezinye izinto kwezinye izinhlelo zokusebenza zokuhlala ngenxa yezindleko. Kodwa-ke, isalokhu ibalulekile ezinhlelweni zamanzi ashisayo ezentengiselwano lapho izinga lokushisa eliphezulu (93°C/200°F) ledlula ezinye izindlela.

Ngenkathi i-PEX isizuze ukuthandwa ngamapayipi asekhaya, i-CPVC igcina izikhundla eziqinile ezindaweni ezintathu ezibalulekile:

1. Izakhiwo zezentengiselwano ezinamasistimu amanzi ashisayo aphakathi nendawo
2. Izicelo zezimboni ezidingayoukumelana kwamakhemikhali
3. Ukubuyisela kabusha amaphrojekthi afana nengqalasizinda ekhona ye-CPVC

Kulezi zimo, ikhono le-CPVC lokusingatha kokubili ukushisa nokucindezela ngaphandle kwezinkinga zokugqwala kwensimbi kuyenza ingenakubekezelelwa. Umbono wokuthi iyashabalala imayelana nokushintsha kwemakethe yezindawo zokuhlala kunokuphelelwa yisikhathi kwezobuchwepheshe.

Ingabe ukufakwa kwe-PVC ne-CPVC kuyahambisana?

Ukuxuba izinto kubukeka njengesinqamuleli esilula, kodwa inhlanganisela engafanele idala amaphuzu abuthakathaka abeka wonke amasistimu engozini.

Cha, azihambelani ngokuqondile. Nakuba bobabili zisebenzisa i-solvent welding, badinga amasimende ahlukene (usimende we-PVC ngeke ubophe kahle i-CPVC futhi ngokuphambene nalokho). Kodwa-ke, ukufakwa koshintsho kuyatholakala ukuze kuxhumeke ngokuphephile lezi zinto ezimbili.

Umehluko wokwakheka kwamakhemikhali kusho ukuthi usimende wabo we-solvent abakwazi ukushintshaniswa:

• I-PVC Cement incibilikisa indawo ye-PVC ukuze ihlanganiswe
• Usimende we-CPVC unamandla ukulandisa ngesakhiwo sawo esiqinile

Ukuzama ukuphoqa ukuhambisana kuholela emalungeni abuthakathaka angase aphumelele ukuhlolwa kwengcindezi ekuqaleni kodwa ahluleke ngokuhamba kwesikhathi. Kwa-Pntek, sihlala sincoma:

1. Ukusebenzisa usimende olungile ohlotsheni lwempahla ngayinye
2. Ukufaka okokufaka okufanele koguquko lapho kudingeka ukuxhumana
3. Ukulebula ngokucacile zonke izingxenye ukuvimbela ukuhlangana

Isiphetho

Amavalvu ebhola e-PVC nawe-CPVC asebenza izindima ezihlukile kodwa ezibalulekile ngokulinganayo—i-PVC yezinhlelo zamanzi abandayo ezingabizi kakhulu kanye ne-CPVC yokufuna izicelo zamanzi ashisayo. Ukukhetha kahle kuqinisekisa ukusebenza okuphephile, okuhlala isikhathi eside. Hlala uqondanisa i-valve nezinga lokushisa elithile lesistimu yakho kanye nezidingo zamakhemikhali ukuze uthole imiphumela emihle.
