Udinga ivalvu engeke ivuze noma iphuke, kodwa i-PVC ibonakala ishibhile kakhulu futhi ilula. Ukukhetha ingxenye engalungile kungasho indawo yokusebenzela egcwele amanzi kanye nesikhathi esibizayo sokuphumula.

Ikhwalithi ephezuluAmavalvu ebhola le-PVCzithembeke kakhulu ngezinhlelo zazo ezihlosiwe. Ukuthembeka kwazo kuvela ekwakhiweni kwazo okulula kanye nokungavikeleki ngokuphelele ekugqwaleni nasekugqwaleni, okuyizindawo eziyinhloko zokwehluleka kwamavalvu ensimbi ezinhlelweni eziningi zamanzi.

Umbuzo wokuthembeka uphakama ngaso sonke isikhathi. Muva nje bengikhuluma noKapil Motwani, umphathi wokuthenga engisebenza naye eNdiya. Uhlinzeka ngezinto zokwakha emabhizinisini amaningi okufuya izinhlanzi kanye nezimfanzi ogwini lolwandle. Babevame ukusebenzisaamavalvu ethusi, kodwa ukufuthwa kwamanzi anosawoti njalo nomoya omanzi bekuzowagqwala esikhathini esingaphansi kweminyaka emibili. Izibambo bezizobamba noma izidumbu zizothola ukuvuza kwemigodi. Lapho ezishintshela ku-Pntek yethuAmavalvu ebhola le-PVC, inkinga yanyamalala. Eminyakeni emihlanu kamuva, lawo ma-valve e-PVC afanayo asebenza kahle. Yilolo hlobo lokuthembeka olubalulekile ezweni langempela.

I-valve yebhola ye-PVC izohlala isikhathi esingakanani?

Ufaka uhlelo futhi udinga ukwethemba izingxenye zalo iminyaka eminingi. Ukuthi uhlale ukhipha futhi ushintsha ama-valve ahlulekile kuyinkinga enkulu kanye nezindleko ofuna ukuzigwema.

Ivalvu yebhola ye-PVC eyenziwe kahle ingahlala iminyaka eyi-10 kuya kwengama-20 kalula, noma isikhathi eside ezimweni ezifanele. Izici ezibalulekile ezinquma isikhathi sayo sokuphila yikhwalithi yezinto ze-PVC, ukuchayeka kwi-UV, ukuhambisana kwamakhemikhali, kanye nokuvama kokusetshenziswa.

Ukuphila isikhathi eside kwevalvu akuyona inombolo eyodwa; kungumphumela oqondile wekhwalithi yayo kanye nokusetshenziswa kwayo. Isici esikhulu kunazo zonke yile nto ngokwayo. Sisebenzisa kuphelaI-PVC engu-100% emsulwaAbakhiqizi abaningi abashibhile basebenzisa“ukugaya kabusha”—izingcezu zepulasitiki ezisetshenziswe kabusha—okungenisa ukungcola futhi okwenza umkhiqizo wokugcina ube buthakathaka futhi uthambekele ekuhlulekeni. Esinye isici esiyinhloko ukukhanya kwelanga. I-PVC ejwayelekile izobuthakathaka ngenxa yokuvezwa yi-UV isikhathi eside, yingakho sikhiqiza izinhlobo ezingamelani ne-UV zokusetshenziswa kwangaphandle njengokunisela. Okokugcina, cabanga ngezivalo zangaphakathi. Amavalvu ethu asebenzisa okubushelelezi, okuhlala isikhathi esideIzihlalo ze-PTFEokungaphatha izinkulungwane zemijikelezo, kanti amavalvu ashibhile avame ukusebenzisa irabha ethambile engadabula noma yonakale ngokushesha, okwenza ivalvu yehluleke ukuvala. Ivalvu esezingeni eliphezulu ayiyona nje ingxenye; iwukutshalwa kwezimali kwesikhathi eside ekuthembekeni.

Izici Ezithinta Isikhathi Sokuphila Sevalvu Ye-PVC

Yiliphi i-brass noma i-PVC ball valve engcono?

Ubona ivalvu yethusi kanye nevalvu ye-PVC ziseceleni. Umehluko wentengo mkhulu kakhulu, kodwa iyiphi empeleni eyisinqumo esingcono sephrojekthi yakho? Isinqumo esingalungile singabiza kakhulu.

Akukho lutho olungcono kakhulu emhlabeni wonke; ukukhetha okungcono kuncike ngokuphelele ekusetshenzisweni. I-PVC ihamba phambili ezindaweni ezigqwalisayo futhi ingabizi kakhulu. Ithusi lingcono kakhulu emazingeni okushisa aphezulu, ukucindezeleka okuphezulu, kanye nezimo ezidinga amandla amakhulu omzimba.

Lona omunye wemibuzo evame kakhulu ebuzwa yithimba likaKapil Motwani. Impendulo cishe itholakala njalo ngokubuza mayelana nesicelo.Ama-PVCamandla amakhulu ukungangeni kwawo kwamakhemikhali. Ayikwazi ukugqwala ngokuphelele. Ezinhlelweni ezisebenzisa amanzi omthombo, umanyolo, amanzi anosawoti, noma ama-asidi athambile, i-PVC izohlala isikhathi eside kakhulu kunethusi. Ithusi lingahlushwa yinto ebizwa ngokuthiukususwa kwe-zincification, lapho ikhemikhali ethile yamanzi ikhipha khona i-zinc ku-alloy, okwenza ibe nezimbobo futhi ibe buthakathaka. I-PVC nayo ilula kakhulu futhi ishibhile kakhulu. Kodwa-ke,ithusiiyona ephumelela kakhulu uma kukhulunywa ngokuqina. Ingamelana namazinga okushisa aphezulu kanye nokucindezeleka kune-PVC, futhi imelana kakhulu nokushaywa ngokomzimba. Uma udinga ivalvu yomugqa wamanzi ashisayo, umugqa womoya ocindezelekile, noma endaweni lapho ingase ishaywe khona, ithusi liyindlela ephephile. Eziningi zezicelo zamanzi abandayo, i-PVC inikeza inani elingcono lesikhathi eside.

I-PVC vs. Ithusi: Ukuqhathanisa Ikhanda Nekhanda

Ingabe ama-valve e-PVC alungile?

Ufuna ikhwalithi, kodwa izindleko eziphansi zama-valve e-PVC zibonakala zinhle kakhulu ukuba zingaba yiqiniso. Ukhathazekile ngokuthi ukonga amadola ambalwa manje kuzoholela ekuhlulekeni okukhulu kamuva.

Yebo, amavalvu e-PVC asezingeni eliphezulu mahle kakhulu futhi anikeza inani eliyingqayizivele ekusetshenzisweni kwawo okuhlosiwe. Ivalvu ye-PVC eyenziwe kahle eyenziwe ngezinto ezihlanzekile ezinezivalo ezinhle iyingxenye eqinile nethembekile kakhulu yezinhlelo eziningi zokuphathwa kwamanzi.

Ingabe ama-valve ebhola e-PVC ayahluleka?

Ufuna ukufaka ingxenye ongasoze wacabanga ngayo futhi. Kodwa yonke ingxenye inephuzu layo eliphukile, futhi ukungazi ukuthi kungaholela ezinhlekeleleni ezingavinjelwa.

Yebo, ama-valve ebhola le-PVC angahluleka, kodwa ukwehluleka cishe njalo kubangelwa ukusetshenziswa kabi noma ukufakwa okungafanele, hhayi ukukhubazeka kwe-valve yekhwalithi. Izimbangela ezivame kakhulu zokwehluleka ukubanda, ukuchayeka kumakhemikhali angahambisani noma amanzi ashisayo, kanye nomonakalo ongokwenyama.

Izindlela Zokuhluleka Ezivamile Nokuvimbela

Isiphetho

Amavalvu ebhola e-PVC asezingeni eliphezulu athembeke kakhulu. Ukumelana kwawo nokugqwala kuwanika inzuzo enkulu kunensimbi ezindaweni eziningi zokusetshenziswa kwamanzi. Ngokukhetha umkhiqizo osezingeni eliphezulu, uqinisekisa ukusebenza kwesikhathi eside nokwethenjelwa.
