Uzama uku-oda ama-valve, kodwa omunye umhlinzeki uwabiza nge-PVC kanti omunye uwabiza nge-UPVC. Lokhu kudideka kukwenza ukhathazeke ngokuthi uqhathanisa imikhiqizo ehlukene noma uthenga izinto ezingalungile.

Kuma-valve ebhola aqinile, akukho mehluko osebenzayo phakathi kwe-PVC ne-UPVC. Womabili la magama abhekisela kulokho okufanayoizinto ze-polyvinyl chloride ezingafakwanga ipulasitiki, eqinile, engagqwali, futhi efanelekile ezinhlelweni zamanzi.

Lona omunye wemibuzo evame kakhulu engiyitholayo, futhi udala ukudideka okungadingekile ochungechungeni lokuhlinzeka. Muva nje bengikhuluma noBudi, umphathi wokuthenga ovela kumsabalalisi omkhulu e-Indonesia. Abathengi bakhe abasha abancane babebambekile, becabanga ukuthi badinga ukuthola izinhlobo ezimbili ezahlukene zamavalvu. Ngamchazela ukuthi kumavalvu aqinile esiwakhiqizayo ePntek, kanye nasembonini eminingi, amagama asetshenziswa ngokushintshana. Ukuqonda ukuthi kungani kuzokunika ukuzethemba ezinqumweni zakho zokuthenga.

Ingabe kukhona umehluko phakathi kwe-PVC ne-UPVC?

Ubona amagama amabili afingqiwe ahlukene bese ucabanga ukuthi amelela izinto ezimbili ezahlukene. Lokhu kungabaza kunganciphisa ijubane lamaphrojekthi akho njengoba uzama ukuqinisekisa imininingwane efanele.

Empeleni, cha. Uma kuqhathaniswa namapayipi aqinile namavalvu, i-PVC ne-UPVC ziyafana. Igama elithi “U” ku-UPVC limelela elithi “unplasticized,” okuyinto esevele iyiqiniso kuwo wonke amavalvu e-PVC aqinile.

Ukudideka kuvela emlandweni wepulasitiki. I-Polyvinyl chloride (PVC) iyisisekelo sezinto zokwakha. Ukuze iguquguquke emikhiqizweni efana namapayipi engadini noma ukufakelwa kwentambo kagesi, abakhiqizi banezela izinto ezibizwa ngokuthi ama-plasticizer. Ukuze bahlukanise uhlobo lokuqala, oluqinile noluguquguqukayo, kwavela igama elithi “unplasticized” noma “UPVC”. Kodwa-ke, ngezinhlelo zokusebenza ezifana nezinhlelo zamanzi ezicindezelwe, awusoze wasebenzisa uhlobo oluguquguqukayo. Wonke amapayipi e-PVC aqinile, izinto zokufakelwa, nama-valve ebhola, ngokwemvelo yawo, awazange aguqulwe ngepulasitiki. Ngakho-ke, ngenkathi ezinye izinkampani zibiza imikhiqizo yazo ngokuthi “UPVC” ngokuthi icacile, kanti ezinye zisebenzisa “i-PVC” evamile, zibhekisela ezintweni ezifanayo eziqinile neziqinile. Kwa-Pntek, sibabiza nje ngokuthiAmavalvu ebhola le-PVCngoba yigama elivame kakhulu, kodwa wonke ngokwezobuchwepheshe angama-UPVC.

Ingabe ama-valve ebhola e-PVC alungile?

Uyabona ukuthi i-PVC iyipulasitiki futhi ibiza kancane kunensimbi. Lokhu kukwenza uzibuze ukuthi ikhwalithi yayo futhi uzibuze ukuthi ingabe ihlala isikhathi eside ngokwanele yini ukuze isetshenziswe isikhathi eside.

Yebo, amavalvu ebhola e-PVC asezingeni eliphezulu alungele injongo yawo ehlosiwe. Avikelekile ekugqwaleni nasekugqwaleni, alula, futhi anikeza impilo ende yesevisi ezindaweni ezibandayo, ngokuvamile enza kahle kakhulu kunevalvu yensimbi.

Inani lawo alikho nje kuphela emananini awo aphansi; lisekusebenzeni kwawo ezindaweni ezithile. Amavalvu ensimbi, njengethusi noma insimbi, azogqwala noma agqwale ngokuhamba kwesikhathi, ikakhulukazi ezinhlelweni ezinamanzi ahlanziwe, amanzi anosawoti, noma amakhemikhali athile. Lokhu kugqwala kungabangela ukuthi ivalvu ibambe, okwenza kube nzima ukuyijika esimweni esiphuthumayo. I-PVC ayikwazi ukugqwala. Ayisebenzi ngamakhemikhali ezithasiselweni eziningi zamanzi, usawoti, nama-asidi athambile. Yingakho amakhasimende kaBudi embonini yezolimo zasemanzini ogwini e-Indonesia esebenzisa amavalvu e-PVC kuphela. Amanzi anosawoti angabhubhisa amavalvu ensimbi eminyakeni embalwa nje, kodwa amavalvu ethu e-PVC ayaqhubeka nokusebenza kahle iminyaka eyishumi noma ngaphezulu. Kunoma yikuphi ukusetshenziswa ngaphansi kuka-60°C (140°F), i-I-valve yebhola ye-PVCakuyona nje inketho "eshibhile"; ngokuvamile kuyisinqumo esithembeke kakhulu nesihlala isikhathi eside ngoba asisoze sabamba ukugqwala.

Yiluphi uhlobo lwe-ball valve olungcono kakhulu?

Ufuna ukuthenga ivalvu "engcono kakhulu" ukuqinisekisa ukuthi uhlelo lwakho luthembekile. Kodwa njengoba kunezinto eziningi kangaka ezitholakalayo, ukukhetha engcono kakhulu kuzwakala kungaphezu kwamandla futhi kuyingozi.

Ayikho ivalvu eyodwa "engcono kakhulu" yebhola kuyo yonke imisebenzi. Ivalvu engcono kakhulu yileyo enezinto zayo kanye nomklamo wayo ohambisana kahle nokushisa kwesistimu yakho, ingcindezi, kanye nendawo yamakhemikhali.

“Okuhle Kakhulu” kuhlale kuhlobene nohlelo lokusebenza. Ukukhetha okungalungile kufana nokusebenzisa imoto yezemidlalo ukuthutha amatshe ayigugu—kuyithuluzi elingalungile lomsebenzi. Ivalvu yensimbi engagqwali inhle kakhulu emazingeni okushisa aphezulu kanye nokucindezela, kodwa ibiza kakhulu ohlelweni lokujikeleza kwamanzi echibini, lapho ivalvu ye-PVC ingcono ngenxa yayoukumelana ne-chlorineNgihlala ngiqondisa ozakwethu ukuthi bacabange ngezimo ezithile zephrojekthi yabo. I-valve ye-PVC iyiqhawe lezinhlelo zamanzi abandayo ngenxa yokumelana kwayo nokugqwala kanye nezindleko. Ngamanzi ashisayo, udinga ukuthuthuka kuI-CPVC. Ngegesi noma uwoyela ocindezelwe kakhulu, ithusi liyindlela yendabuko nethembekile. Ngezicelo zokudla noma amakhemikhali abola kakhulu, insimbi engagqwali ivame ukudingeka. Ukukhetha "okungcono kakhulu" ngempela yileyo enikeza ukuphepha okudingekayo kanye nokuphila isikhathi eside ngezindleko eziphansi kakhulu.

Umhlahlandlela Wezinto Zevalvu Yebhola

Uyini umehluko phakathi kwe-PVC U ne-UPVC?

Ngesikhathi nje ucabanga ukuthi uyayiqonda i-PVC uma uyiqhathanisa ne-UPVC, ubona i-“PVC-U” kudokhumenti yobuchwepheshe. Leli gama elisha lengeza olunye ungqimba lokudideka, okwenza ungabaza ukuqonda kwakho.

Akukho mehluko nhlobo. I-PVC-U ingenye nje indlela yokubhala i-uPVC. Igama elithi “-U” liphinde lisho ukuthi ayifakwanga ipulasitiki. Kuyindlela yokuqamba amagama evame ukubonwa ezindinganisweni zaseYurophu noma zamazwe ngamazwe (njenge-DIN noma i-ISO).

Cabanga ngakho njengokusho ukuthi “amadola ayi-100” uma kuqhathaniswa nokuthi “amadola ayi-100.” Lawa ngamagama ahlukene ento efanayo. Ezweni lamapulasitiki, izifunda ezahlukene zakha izindlela ezihlukile zokulebula lokhu. ENyakatho Melika, igama elithi “PVC” liyigama elivamile lepayipi eliqinile, kanti elithi “UPVC” ngezinye izikhathi lisetshenziselwa ukucaca. EYurophu nangaphansi kwezindinganiso zomhlaba wonke, elithi “PVC-U” liyigama lobunjiniyela elisemthethweni kakhulu lokuchaza “okungafakwanga ipulasitiki.” Kumthengi onjengoBudi, lokhu kuyisici esibalulekile solwazi eqenjini lakhe. Lapho bebona ithenda yaseYurophu echaza amavalvu e-PVC-U, bazi ngokuqiniseka ukuthi amavalvu ethu e-PVC ajwayelekile ahlangabezana nesidingo ngokuphelele. Konke kuncike ezintweni ezifanayo: i-polymer eqinile, eqinile, engafakwanga ipulasitiki efanelekile kumavalvu ebhola. Ungabanjwa yizinhlamvu; gxila ezimpahleni zezinto kanye nezindinganiso zokusebenza.

Isiphetho

I-PVC, i-UPVC, kanye ne-PVC-U konke kubhekisela ezintweni ezifanayo eziqinile, ezingenapulasitiki ezifanele ama-valve ebhola lamanzi abandayo. Umehluko wamagama umane nje uyimithetho yesifunda noma yomlando.
