Udinga ukukhetha ivalvu, kodwa izinketho zethusi ne-PVC zinezinselelo ezinkulu zamanani. Ukukhetha okungalungile kungaholela ekugqwaleni, ekuvuzeni, noma ekusebenziseni imali eningi kakhulu.

Umehluko omkhulu yizinto ezenziwe ngazo: I-PVC iyipulasitiki elula engagqwali ngokuphelele futhi ilungele amanzi abandayo. Ithusi liyingxube yensimbi esindayo neqinile engamelana namazinga okushisa aphezulu kanye nokucindezeleka kodwa ingagqwala ngokuhamba kwesikhathi.

Lona mhlawumbe umbuzo ovame kakhulu engiwutholayo. Bengixoxa nje noBudi, umphathi wokuthenga engisebenza naye e-Indonesia. Udinga ukunikeza ithimba lakhe lokuthengisa izimpendulo ezicacile nezilula kumakhasimende abo, kusukela kubalimi kuya kubaphangi bamapayipi kuya kubakhi bamachibi okubhukuda. Abameleli bakhe abahle kakhulu abagcini nje ngokuthengisa izingxenye; baxazulula izinkinga. Futhi isinyathelo sokuqala sokuxazulula inkinga ukuqonda umehluko oyisisekelo phakathi kwamathuluzi. Uma kukhulunywa ngethusi uma kuqhathaniswa ne-PVC, umehluko mkhulu kakhulu, futhi ukukhetha okulungile kubalulekile ohlelweni oluphephile noluhlala isikhathi eside. Ake sihlaziye kahle lokho okudingeka ukwazi.

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

Ubheka ama-valve amabili, elinye liyipulasitiki eshibhile kanti elinye liyinsimbi ebizayo. Ingabe elensimbi lifanele ngempela imali eyengeziwe? Ukukhetha okungalungile kungaba yiphutha elibizayo.

Akukho lutho olungcono kakhulu emhlabeni wonke. I-PVC iyindlela engcono kakhulu ezindaweni ezigqwalisayo nazo zonke izinhlobo zamanzi abandayo ajwayelekile. Ithusi lingcono emazingeni okushisa aphezulu, ukucindezeleka okuphezulu, kanye nalapho amandla angokomzimba eza kuqala.

Umbuzo wokuthi yikuphi "okungcono" uhlala uncike emsebenzini othize. Kwabaningi bamakhasimende kaBudi abakha amapulazi okufuya izilwane zasolwandle ogwini, i-PVC ingcono kakhulu. Umoya namanzi anosawoti kungadla ama-valve ethusi, okubangela ukuba abambe noma avuza phakathi neminyaka embalwa.Amavalvu e-PVCazithinteki nhlobo usawoti futhi zizohlala amashumi eminyaka. Kodwa-ke, uma ikhasimende linguplamba ofaka isifudumezi samanzi ashisayo, i-PVC ayiyona inketho. Ingathamba futhi yehluleke. Kuleso simo, ithusi liwukuphela kwesinqumo esifanele ngenxa yokubekezelela kwayo ukushisa okuphezulu. I-PVC nayo ayivikelekile ekususweni kwe-zinc, inqubo lapho izinhlobo ezithile zamanzi zingakhipha i-zinc kuthusi, okwenza liqhekeke. Emisebenzini eminingi yamanzi abandayo, i-PVC inikeza ukuthembeka okungcono kwesikhathi eside kanye nenani.

I-PVC vs. Ithusi: Yikuphi Okungcono?

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

Iphampu yakho ilahlekelwa yi-prime yayo njalo, okuphoqa ukuthi uyiqale kabusha njalo. Udinga ivalvu yonyawo engeke yehluleke, kodwa izobe ingaphansi kwamanzi futhi ingabonakali.

Eziningi zezicelo zepompo yamanzi, ivalvu yezinyawo ye-PVC ingcono kakhulu. Ilula, okunciphisa ukucindezeleka epayipini, futhi ngokungafani nethusi, ayigonyelwa ngokuphelele ukugqwala nokugqwala okubangela ukwehluleka kwevalvu yezinyawo eziningi.

Ivalvu yonyawo iphila impilo enzima. Ihlala phansi komthombo noma ethangini, ihlale icwiliswe emanzini. Lokhu kwenza ukugqwala kube yisitha sayo sokuqala. Nakuba ithusi libonakala liqinile, lokhu kucwiliswa okuqhubekayo yilapho lisengozini khona kakhulu. Ngokuhamba kwesikhathi, amanzi azogqwala insimbi, ikakhulukazi isiphethu sangaphakathi esithambile noma indlela yokubopha, okubangela ukuba ivuleke noma ivalwe. Ivalvu yehluleka ukubamba i-prime noma ivimbe amanzi ukuthi angagelezi nhlobo. Ngenxa yokuthi i-PVC iyipulasitiki, ayikwazi ukugqwala. Izingxenye zangaphakathi zamavalvu ethu onyawo e-Pntek nazo zenziwe ngezinto ezingagqwali, ngakho-ke zingahlala ngaphansi kwamanzi iminyaka eminingi futhi zisebenze kahle. Enye inzuzo enkulu isisindo. Ivalvu yonyawo olunzima lwethusi ibeka ukucindezeleka okukhulu epayipini lokumunca, okungenzeka libangele ukuthi ligobe noma liphuke. IlulaI-valve yonyawo lwe-PVCKulula kakhulu ukuyifaka nokusekela.

I-valve yebhola ye-PVC isetshenziselwa ini?

Unephrojekthi enemigqa eminingi yamanzi. Udinga indlela engabizi futhi ethembekile yokulawula ukugeleza kwamanzi kuyo ngayinye ngaphandle kokukhathazeka ngezinkinga zesikhathi esizayo ezivela ekugqwaleni noma ekuboleni.

I-valve yebhola ye-PVC isetshenziselwa ukunikeza ukulawula okusheshayo kokuvula/ukuvala izinhlelo zamanzi abandayo. Yindlela ekhethwayo yokunisela, amachibi okubhukuda, ukufuya izilwane zasemanzini, kanye namapayipi ajwayelekile lapho izindleko zayo eziphansi kanye nokumelana nokugqwala kubaluleke kakhulu.

Ake sibheke imisebenzi ethile lapho i-PVC iphumelela khona.ukunisela kanye nokulima, lawa mavalvu aphelele. Angagqitshwa emhlabathini noma asetshenziswe kanye nemigqa yomanyolo ngaphandle kwengozi yokugqwala ngenxa yomswakama noma amakhemikhali.amachibi okubhukuda nama-spa, Amapayipi e-PVC ayindlela ejwayelekile embonini ngesizathu esithile. Ayithintwa nhlobo yi-chlorine, usawoti, kanye namanye amakhemikhali echibi angabhubhisa ngokushesha izingxenye zensimbi. Ngihlala ngitshela uBudi ukuthiukulima izinhlanziImakethe ifanelana kahle. Abafuyi bezinhlanzi badinga ukulawulwa kwamanzi okuqondile, futhi abakwazi ukuba nensimbi egeleza emanzini bese ilimala imfuyo yabo. I-PVC ayisebenzi, iphephile, futhi ithembekile. Okokugcina, kunoma yimuphi umsebenzi wamanzi abandayo, njengokuvala okuyinhloko kohlelo lokufafaza noma ipayipi elilula, ivalvu yebhola le-PVC inikeza ikhambi elingabizi, elinomlilo bese ukhohlwa owaziyo ukuthi lizosebenza uma ulidinga.

Isetshenziswa kanjani ivalvu yebhola lethusi?

Ufaka amanzi ashisayo noma umoya ocindezelwe entanjeni. Ivalvu ejwayelekile yepulasitiki ingaba yingozi futhi ingaqhuma. Udinga ivalvu enamandla ngokwanele ukwenza umsebenzi.

A ivalvu yebhola lethusiisetshenziselwa izinhlelo zokusebenza ezidinga ukubekezelela ukushisa okuphezulu, izilinganiso zokucindezela okuphezulu, kanye nokuqina okukhulu ngokomzimba. Ukusetshenziswa kwayo okuvame kakhulu kwemigqa yamanzi ashisayo, amapayipi egesi yemvelo, kanye nezinhlelo zomoya ezicindezelwe zezimboni.

Ithusi liyihhashi elinzima lemisebenzi i-PVC engenakukwazi ukuyisingatha. Amandla alo amakhulu yi-ukumelana nokushisa. Nakuba i-PVC ithambisa ngaphezu kuka-140°F (60°C), ithusi lingamelana kalula namazinga okushisa angaphezu kuka-200°F (93°C), okwenza kube yilona kuphela ukhetho lwama-heater amanzi ashisayo kanye neminye imigqa yoketshezi olushisayo. Inzuzo elandelayo yileingcindezi. Ivalvu yebhola ye-PVC ejwayelekile ivame ukulinganiselwa ku-150 PSI. Amavalvu amaningi ebhola lethusi alinganiselwa ku-600 PSI noma ngaphezulu, okwenza abaluleke kakhulu ezinhlelweni zokucindezela okuphezulu njengeimigqa yomoya ecindezelweEkugcineni, kukhonaamandla ezinto ezibonakalayo. Kokufaka amapayipiigesi yemvelo, imithetho yokwakha ihlala idinga ama-valve ensimbi njengethusi. Uma kwenzeka umlilo, i-valve yepulasitiki ingancibilikisa futhi ikhiphe igesi, kuyilapho i-valve yethusi ingahlala ingashintshi. Kunoma yikuphi ukusetshenziswa lapho ukushisa, umfutho ophezulu, noma ukuphepha komlilo kuyinkinga, ithusi liyisinqumo esifanele nesiwukuphela kochwepheshe.

Isiphetho

Ukukhetha phakathi kwe-PVC nethusi kumayelana nokusetshenziswa. Khetha i-PVC ngenxa yokumelana kwayo nokugqwala okunganqobeki emanzini abandayo bese ukhetha ithusi ngenxa yamandla ayo ekushiseni nasekucindezelweni okuphezulu.
