Udinga ukukhetha i-valve, kodwa izinketho zethusi ne-PVC zinezikhala ezinkulu zamanani. Ukukhetha okungalungile kungaholela ekugqwaleni, ekuvuzeni, noma ekuchitheni imali kakhulu.

Umehluko omkhulu yizinto ezibonakalayo: I-PVC iyipulasitiki engasindi engavikelekile ngokuphelele ekugqwaleni futhi ilungele amanzi abandayo. I-Brass iyingxube yensimbi esindayo, eqinile ekwazi ukumelana namazinga okushisa aphezulu nezingcindezi kodwa ingagqwala ngokuhamba kwesikhathi.

Lona cishe umbuzo ovame kakhulu engiwutholayo. Bengixoxa ngakho noBudi, umphathi wokuthenga engisebenza naye e-Indonesia. Udinga ukunikeza ithimba lakhe labadayisi izimpendulo ezicacile, ezilula kumakhasimende abo, kusukela kubalimi kuya kwabasebenza ngamapayipi amanzi kuya kumakhi ahlanganisa ndawonye. Abameli bakhe abahamba phambili abathengisi nje izingxenye; baxazulula izinkinga. Futhi isinyathelo sokuqala sokuxazulula inkinga ukuqonda umehluko oyisisekelo phakathi kwamathuluzi. Uma kukhulunywa ngethusi uma kuqhathaniswa ne-PVC, umehluko mkhulu, futhi ukukhetha okulungile kubalulekile ohlelweni oluphephile, oluhlala isikhathi eside. Ake sihlukanise lokho odinga ukukwazi.

Imaphi ama-valve ebhola ethusi noma e-PVC angcono?

Ubheka ama-valve amabili, eyodwa iyipulasitiki eshibhile kanti enye iyinsimbi ebizayo. Ingabe eyensimbi iyifanele ngempela imali eyengeziwe? Ukukhetha okungalungile kungaba iphutha elibizayo.

Ayikho into engcono emhlabeni jikelele. I-PVC iyisinqumo esingcono sezindawo ezonakalisayo kanye nazo zonke izinhlelo zokusebenza zamanzi abandayo ezijwayelekile. I-Brass ingcono kumazinga okushisa aphezulu, ukucindezela okuphezulu, nalapho amandla omzimba ebaluleke kakhulu.

Umbuzo wokuthi yikuphi "okungcono" njalo ufika emsebenzini othize. Kumakhasimende amaningi akwa-Budi akha amapulazi ezilwane zasemanzini ngasogwini, i-PVC ingcono kakhulu. Umoya onosawoti kanye namanzi bekungagqwala amavalvu ethusi, kubangele ukuthi abambe noma avuze phakathi neminyaka embalwa. EyethuAma-valve e-PVCazithintwa ngokuphelele usawoti futhi zizohlala amashumi eminyaka. Kodwa-ke, uma ikhasimende liyi-plumber efaka i-heater yamanzi ashisayo, i-PVC akuyona inketho. Yayizothamba ihluleke. Kuleso simo, ithusi liwukuphela kwesinqumo esifanele ngenxa yokubekezelela ukushisa okukhulu. I-PVC iphinde ivikeleke ekwenziweni kwe-dezincification, inqubo lapho izinhlobo ezithile zamanzi zingakhipha i-zinc ethusi, iyenze ibe brittle. Emisebenzini eminingi yamanzi abandayo, i-PVC inikeza ukwethembeka okungcono kwesikhathi eside kanye nenani.

I-PVC vs. Brass: Yikuphi Okungcono?

Imaphi ama-valve ezinyawo zethusi noma e-PVC angcono?

Iphampu yakho ilokhu ilahlekelwa amandla ayo, okukuphoqa ukuthi uyiqale kabusha njalo. Udinga i-valve yonyawo engeke yehluleke, kodwa izoba ngaphansi kwamanzi futhi ingabonakali.

Eziningi zezinhlelo zokusebenza zepompo yamanzi, i-valve yonyawo lwe-PVC ingcono kakhulu. Ilula, enciphisa ukucindezelwa kwepayipi, futhi ngokungafani nethusi, ivikeleke ngokuphelele ekugqwaleni nokugqwala okubangela ukwehluleka okuningi kwe-valve yonyawo.

I-valve yonyawo iphila impilo enzima. Ihlala phansi komthombo noma ithangi, ihlale icwile emanzini. Lokhu kwenza ukugqwala kube isitha sakho sokuqala. Nakuba ithusi libonakala liqinile, lokhu kucwiliswa njalo kulapho kusengozini khona kakhulu. Ngokuhamba kwesikhathi, amanzi azogqwala insimbi, ikakhulukazi umshini othambile wangaphakathi we-spring noma wehinge, okubangela ukuba ibambe ivuleke noma ivaleke. I-valve ihluleka ukubamba i-prime noma ivimbele amanzi ukuthi angagelezi nhlobo. Ngenxa yokuthi i-PVC iyipulasitiki, ayikwazi ukugqwala. Izingxenye zangaphakathi zamavalvu ethu ezinyawo ze-Pntek nazo zenziwe ngezinto ezingagqwali, ngakho zingakwazi ukuhlala ngaphansi kwamanzi iminyaka futhi zisasebenza kahle. Enye inzuzo enkulu isisindo. I-valve yezinyawo zethusi esindayo ibeka ingcindezi enkulu epayipini lokumunca, okungenzeka libangele ukuthi ligobe noma liphuke. A engasindiI-valve yonyawo ye-PVCkulula kakhulu ukuyifaka nokusekela.

Isetshenziselwa ini i-valve yebhola ye-PVC?

Unephrojekthi enemigqa eminingi yamanzi. Udinga indlela ethengekayo nethembekile yokulawula ukugeleza kokukodwa ngaphandle kokukhathazeka ngezinkinga zesikhathi esizayo zokugqwala noma ukubola.

I-valve yebhola ye-PVC isetshenziselwa ukunikeza ukulawula okusheshayo kokuvula/ukuvala ezinhlelweni zamanzi abandayo. Kuyiyona ndlela ongakhetha kuyo ngokunisela, amachibi okubhukuda, i-aquaculture, kanye namapayipi ajwayelekile lapho izindleko zakhona eziphansi kanye nemvelo yokungagqwali ibalulekile.

Ake sibheke imisebenzi ethile lapho i-PVC ihamba phambili. Ngobaukuchelela nokulima, lama-valve aphelele. Zingagqitshwa emhlabathini noma zisetshenziswe ngemigqa kamanyolo ngaphandle kwengozi yokugqwala okuvela kumswakama noma amakhemikhali. Ngobaamachibi okubhukuda kanye nezipa, PVC amapayipi indinganiso yemboni ngesizathu. Ayithinteki ngokuphelele i-chlorine, usawoti, namanye amakhemikhali e-pool angabhubhisa ngokushesha izingxenye zensimbi. Ngihlale ngitshela uBudi ukuthiukulima kwezilwane zasemanziniimakethe ilingana kahle. Abalimi bezinhlanzi badinga ukulawulwa kwamanzi okunembile, futhi abakwazi ukuba nensimbi engena emanzini futhi balimaze isitokwe sabo. I-PVC ayisebenzi, iphephile, futhi inokwethenjelwa. Okokugcina, kunoma yimuphi umsebenzi ojwayelekile wamanzi abandayo, njengokuvala okuyinhloko kwesistimu yokufafaza noma i-drain elula, i-valve yebhola ye-PVC inikeza isisombululo esingabizi kakhulu, somlilo kanye nokukhohlwa owaziyo ukuthi sizosebenza uma usidinga.

Isetshenziselwa ini i-valve yebhola lethusi?

Ufaka amapayipi amanzi ashisayo noma umoya ocindezelwe. Ivalvu yepulasitiki ejwayelekile ingaba yingozi futhi ingaqhuma. Udinga i-valve eqine ngokwanele ukwenza umsebenzi.

A i-valve yebhola yethusiisetshenziselwa izinhlelo zokusebenza ezinzima ezidinga ukubekezelela ukushisa okuphezulu, izilinganiso zokucindezela okuphezulu, nokuqina komzimba okukhulu. Ukusetshenziswa kwawo okuvame kakhulu olayini bamanzi ashisayo, amapayipi egesi yemvelo, kanye nezinhlelo zomoya ezicindezelwe yizimboni.

I-Brass iyihhashi lokusebenza lemisebenzi i-PVC engeke ikwazi ukuyiphatha. Amandla ayo amakhulu kakhuluukumelana nokushisa. Nakuba i-PVC ithamba ngaphezu kuka-140°F (60°C), ithusi lingakwazi ukuphatha kalula amazinga okushisa angaphezu kuka-200°F (93°C), okuyenza kube ukuphela kwenketho yezishisi zamanzi ashisayo neminye imigqa yoketshezi olushisayo. Inzuzo elandelayoingcindezi. I-valve yebhola ye-PVC evamile ngokuvamile ilinganiselwa ku-150 PSI. Ama-valve amaningi ebhola ethusi alinganiselwe ku-600 PSI noma ngaphezulu, okuwenza abebalulekile ezinhlelweni zokucindezela okuphezulu njengeimigqa yomoya ecindezelwe. Ekugcineni, kukhonaamandla ezinto ezibonakalayo. Okwamapayipiigesi yemvelo, amakhodi wokwakha ahlala edinga ama-valve ensimbi njengethusi. Uma kwenzeka umlilo, i-valve yepulasitiki ingancibilika futhi ikhulule igesi, kuyilapho i-valve yethusi izohlala injalo. Kunoma isiphi isicelo lapho ukushisa, umfutho ophezulu, noma ukuphepha komlilo kuwukukhathazeka, ithusi liyisinqumo esilungile nesiwuchwepheshe kuphela.

Isiphetho

Ukukhetha phakathi kwe-PVC nethusi kumayelana nesicelo. Khetha i-PVC ngokumelana nokugqwala okungenakunqotshwa emanzini abandayo bese ukhetha ithusi lamandla ayo ngokumelene nokushisa nokucindezela okuphezulu.
