Ufake i-valve entsha yebhola ye-PVC futhi ulindele ukuthi isebenze iminyaka. Kodwa ukwehluleka kungazelelwe kungabangela isikhukhula, kulimaze amathuluzi, futhi kuvalwe imisebenzi.

Ivalvu yebhola ye-PVC yekhwalithi ephezulu ingahlala iminyaka engama-20 ezimeni ezifanele. Nokho, ukuphila kwayo kwangempela kunqunywa izici ezifana nokuchayeka kwe-UV, ukuthintana namakhemikhali, izinga lokushisa lamanzi, ukucindezela kwesistimu, nokuthi isetshenziswa kangaki.

Leso sibalo seminyaka engama-20 siyisiqalo, akusona isiqinisekiso. Impendulo yangempela ithi "kuya ngokuthi." Bengikhuluma ngalokhu noBudi, umphathi wokuthenga engisebenza naye e-Indonesia. Ubona i-spectrum egcwele. Amanye amakhasimende anawoama-valve ethuukusebenza kahle ezinhlelweni zezolimo emva kweminyaka eyi-15. Abanye baye baba nama-valve ehluleka phakathi neminyaka emibili. Umehluko akuwona neze ivalvu ngokwayo, kodwa indawo ehlala kuyo. Ukuqonda lezi zici zemvelo kuwukuphela kwendlela yokubikezela ukuthi ivalvu yakho izohlala isikhathi esingakanani futhi uqiniseke ukuthi ifinyelela amandla ayo aphelele.

Ingakanani iminyaka yokuphila ye-valve yebhola ye-PVC?

Ufuna inombolo elula yohlelo lwakho lwephrojekthi. Kodwa ukusekela umugqa wakho wesikhathi kanye nesabelomali ekuqageleni kuyingozi, ikakhulukazi uma i-valve ihluleka isikhathi eside ngaphambi kokuba uyilindele.

Isikhathi sokuphila se-valve yebhola ye-PVC sisukela eminyakeni embalwa kuya ngaphezu kwamashumi amabili eminyaka. Lokhu akulungisiwe. Isikhathi sokuphila sincike ngokuphelele endaweni yayo yokusebenza kanye nekhwalithi yezinto zayo.

Cabanga ngokuphila kwevalvu njengesabelomali. Iqala eminyakeni engu-20, futhi zonke izimo ezinzima “zichitha” enye yaleyo mpilo ngokushesha. Izindleko ezinkulu kakhulu ukukhanya kwelanga kwe-UV nokusetshenziswa njalo. Ivalvu evulwa futhi ivalwe izikhathi ezingamakhulu ngosuku izoguga izigxivizo zayo zangaphakathi ngokushesha kakhulu kunaleyo ephendulwa kanye ngenyanga. Ngokufanayo, ivalvu efakwe ngaphandle elangeni eliqondile izoba brittle futhi ibe buthakathaka ngokuhamba kwesikhathi. Imisebe ye-UV ihlasela izibopho zamangqamuzana kuPVC. Ngemva kweminyaka embalwa, ingaba ntekenteke kangangokuthi ukungqongqoza okuncane kungase kuyibhidlize. Ukuhambisana kwamakhemikhali, amazinga okushisa aphezulu, nokucindezela okweqile nakho kunciphisa ukuphila kwayo. Ai-valve yekhwalithieyenziwe nge-100% ye-PVC eyintombi enezihlalo eziqinile ze-PTFE izohlala isikhathi eside kakhulu kune-valve eshibhile enama-filler, kodwa ngisho ne-valve engcono kakhulu izohluleka kusenesikhathi uma isetshenziswe ezimweni ezingalungile.

Izinto Ezinciphisa I-PVC Valve Lifespan

Athembeke kangakanani ama-valve ebhola e-PVC?

I-PVC ibukeka njengepulasitiki, futhi ipulasitiki ingazizwa ibuthakathaka. Ukhathazeka ngokuthi ingase iphuke noma ivuze ngaphansi kwengcindezi, ikakhulukazi uma iqhathaniswa nevalve yensimbi esindayo.

Amavalvu ebhola ekhwalithi ephezulu e-PVC athembeke ngokwedlulele ezinhlelweni zawo ezihlosiwe. Ukwakhiwa kwazo kwepulasitiki kusho ukuthi azivikeleki ngokuphelele ekugqwaleni nakuma-mineral buildup okwenza ama-valve ensimbi ahluleke noma abambe ngokuhamba kwesikhathi.

Ukwethembeka akukhona nje ngokuqhuma. Kumayelana nokuthi i-valve iyasebenza uma uyidinga. UBudi wangixoxela indaba ngomunye wamakhasimende akhe embonini yezokulima emanzini. Babevame ukusebenzisa ama-valve ebhola ethusi, kodwa amanzi anosawoti omncane abenza bagle. Ngemva konyaka, ama-valve ayeseqinile ngenxa yokugqwala kangangokuthi ayengakwazi ukuphenduka. Kwadingeka bashintshwe. Bashintshele kumavalvu ethu ebhola e-PVC. Eminyakeni emihlanu kamuva, lawo mavalvu afanayo e-PVC aphenduka kahle njengosuku afakwa ngalo. Lokhu ukuthembeka kweqiniso kwe-PVC. Ayigqwali. Ayivaleki ngesikali noma idiphozithi yamaminerali. Inqobo nje uma isetshenziswa ngaphakathi kwemikhawulo yayo yengcindezi/izinga lokushisa futhi ivikelekile ku-UV, ukusebenza kwayo ngeke kwehliswe. Ivalvu yekhwalithi ye-PVC enobusheleleziIzihlalo ze-PTFEfuthi enokwethenjelwaEPDM O-izindandathoinikeza izinga lesikhathi eside, ukwethembeka okungabikezelwa ukuthi insimbi ngokuvamile ayikwazi ukufana nezinhlelo zamanzi.

Ama-valve ebhola alungele isikhathi esingakanani?

Uqhathanisa i-valve ye-PVC neyethusi. Eyensimbi izwakala isinda kakhulu, ngakho-ke kufanele ibe ngcono, akunjalo? Lokhu kucabanga kungaholela ekukhetheni i-valve engalungile yomsebenzi.

Ama-valve ebhola mahle amashumi eminyaka uma esetshenziswa ngendlela efanele. Ku-PVC, lokhu kusho ukufakwa kwamanzi abandayo ngaphandle kokuchayeka kwe-UV okuqondile. Ngensimbi, kusho amanzi ahlanzekile, angagqwali. AI-valve ye-PVCngokuvamile idlula ai-valve yensimbiezindaweni ezinolaka.

"Kuzothatha isikhathi esingakanani?" empeleni umbuzo othi "Kulungele ini?" I-valve yebhola yensimbi engagqwali esezingeni eliphezulu iyamangalisa, kodwa akuyona inketho enhle yechibi lokubhukuda elinamanzi ane-chlorine, elingahlasela insimbi ngokuhamba kwesikhathi. I-valve yethusi iyisinqumo esihle senhloso evamile, kodwa izohluleka ezinhlelweni ezinomanyolo othile noma amanzi ane-asidi. Yilapho i-PVC ikhanya khona. Kuyisinqumo esingcono kakhulu sohlu olukhulu lwezinhlelo zokusebenza ezisekelwe emanzini, okuhlanganisa ukuchelela, ukufuywa kwezilwane zasemanzini, amachibi, kanye nokufaka amapayipi okuvamile. Kulezi zindawo, ngeke igle, ngakho igcina ukusebenza kwayo kahle iminyaka. Nakuba ingalungile emanzini ashisayo noma izingcindezi eziphezulu, inketho ephakeme ye-niche yayo ethile. Ivalvu ye-PVC esetshenziswe ngendlela efanele "izoba yinhle" isikhathi eside kunevalvu yensimbi esetshenziswe ngokungalungile. Amakhasimende kaBudi aphumelele kakhulu yilawo afanisa impahla yevalvu namanzi, hhayi nje ukubona amandla.

Ingabe ama-valve ebhola ahamba kabi?

I-valve yakho iyekile ukusebenza. Uyazibuza ukuthi ivele yaguga noma kukhona okudale ukuthi ihluleke. Ukwazi ukuthi kungani ihlulekile kuyisihluthulelo sokuyivimbela ngokuzayo.

Yebo, ama-valve ebhola ahamba kabi ngenxa yezizathu ezimbalwa ezicacile. Ukwehluleka okuvame kakhulu ama-seal agugile ngenxa yokusetshenziswa njalo, ukuwohloka kwe-UV okubangela ukonakala, ukuhlaselwa kwamakhemikhali ezintweni ezisetshenziswayo, noma ukulimala komzimba okubangelwa umthelela noma ukuqina ngokweqile.

Ama-valve amabhola awamane ayeke ukusebenza ngenxa yobudala; ingxenye ethile iyehluleka. Iphuzu elivame kakhulu lokuhluleka yizimpawu zangaphakathi. Izihlalo ze-PTFE ezivala ibhola zingaguga ngemva kwezinkulungwane zemijikelezo evulekile/evalayo, okuholela ekuvuzeni okuncane. Amasongo e-EPDM O-esiqwini nawo angaguga, abangele ukuvuza esibambo. Lokhu ukuguga okuvamile. Isizathu sesibili esikhulu ukulimala kwemvelo. Njengoba sixoxile, ukukhanya kwe-UV kuwumbulali, okwenza umzimba we-valve ube brittle. Ikhemikhali engalungile ingenza i-PVC ithambe noma ibhubhise ama-O-rings. Indlela yesithathu abahamba ngayo kabi ngokufaka okungafanele. Iphutha elivame kakhulu engilibonayo abantu baqinisa kakhulu ama-valve e-PVC anentambo. Basonga itheyiphu yentambo eningi kakhulu bese besebenzisa i-wrench enkulu, engaqhekeza umzimba we-valve khona lapho ekuxhumekeni. Ukuqonda lezi zindlela zokwehluleka kukusiza ukuthi uvikele utshalomali lwakho futhi uqinisekise ukuthi luhlala njalo.

Isiphetho

I-valve yekhwalithi ye-PVC ingahlala amashumi eminyaka. Ukuphila kwayo kuncike kancane esikhathini nangaphezulu ekusetshenzisweni okufanele, ukuvikela ekukhanyeni kwe-UV, kanye nedizayini yesistimu efanele yokusetshenziswa kwayo.
