Ufake i-valve entsha yebhola ye-PVC futhi ulindele ukuthi isebenze iminyaka eminingi. Kodwa ukwehluleka okungazelelwe kungabangela izikhukhula, konakalise imishini, futhi kuvalwe ukusebenza.

Ivalvu yebhola ye-PVC esezingeni eliphezulu ingahlala iminyaka efinyelela kwengu-20 ezimweni ezifanele. Kodwa-ke, isikhathi sayo sokuphila sinqunywa yizici ezifana nokuchayeka kwi-UV, ukuthintana kwamakhemikhali, izinga lokushisa kwamanzi, ingcindezi yesistimu, nokuthi isetshenziswa kangaki.

Leso sibalo seminyaka engu-20 siyindawo yokuqala, hhayi isiqinisekiso. Impendulo yangempela ithi “kuya ngokuthi kuncike kuphi.” Bengikhuluma ngalokhu noBudi, umphathi wokuthenga engisebenza naye e-Indonesia. Uyabona konke. Amanye amakhasimende anakhoamavalvu ethuisebenza kahle ezinhlelweni zezolimo ngemva kweminyaka eyi-15. Abanye baye baba nama-valve angasebenzi kahle ngaphansi kweminyaka emibili. Umehluko awuyona i-valve uqobo, kodwa indawo ehlala kuyo. Ukuqonda lezi zici zemvelo kuyindlela kuphela yokubikezela ukuthi i-valve yakho izohlala isikhathi esingakanani ngempela nokuqinisekisa ukuthi ifinyelela amandla ayo aphelele.

Iyini isikhathi sokuphila sevalvu yebhola le-PVC?

Ufuna inombolo elula yohlelo lwakho lwephrojekthi. Kodwa ukusekela isikhathi sakho kanye nesabelomali ekuqageleni kuyingozi, ikakhulukazi uma ivalvu yehluleka isikhathi eside ngaphambi kokuba ulindele.

Isikhathi sokuphila sevalvu yebhola le-PVC sisukela eminyakeni embalwa kuya eminyakeni engaphezu kwamashumi amabili. Lokhu akukalungiswa. Isikhathi sokuphila sincike ngokuphelele endaweni yokusebenza kwayo kanye nekhwalithi yezinto zayo.

Cabanga ngokuphila kwevalvu njengesabelomali. Iqala eminyakeni engama-20, futhi zonke izimo ezinzima "zichitha" ingxenye yaleyo mpilo ngokushesha. Izinto ezisetshenziswa kakhulu ukukhanya kwelanga kwe-UV kanye nokusetshenziswa njalo. Ivalvu evulwa futhi ivalwe izikhathi ezingamakhulu ngosuku izoguga izivalo zayo zangaphakathi ngokushesha kakhulu kuneyo ephendulwa kanye ngenyanga. Ngokufanayo, ivalvu efakwe ngaphandle elangeni eliqondile izophuka futhi ibe buthakathaka ngokuhamba kwesikhathi. Imisebe ye-UV ihlasela izibopho zama-molecule ku-PVC. Ngemva kweminyaka embalwa, ingaba buthakathaka kangangokuthi ukushayisana okuncane kungayiphula. Ukuhambisana kwamakhemikhali, amazinga okushisa aphezulu, kanye nokucindezela okukhulu nakho kunciphisa impilo yayo.i-valve yekhwalithiezenziwe nge-PVC engu-100% engeyona eyemvelo enezihlalo ze-PTFE eziqinile zizohlala isikhathi eside kakhulu kunevalvu eshibhile enezigcwalisi, kodwa ngisho nevalvu engcono kakhulu izohluleka kusenesikhathi uma isetshenziswa ezimweni ezingalungile.

Izici Ezinciphisa Isikhathi Sokuphila Sevalvu Ye-PVC

Ama-valve ebhola e-PVC athembeke kangakanani?

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

Amavalvu ebhola e-PVC asezingeni eliphezulu athembeke kakhulu ekusetshenzisweni kwawo okuhlosiwe. Ukwakhiwa kwawo kwepulasitiki kusho ukuthi awakwazi ukugqwala nokuqongelela kwamaminerali okubangela ukuthi amavalvu ensimbi ahluleke noma abambeke ngokuhamba kwesikhathi.

Ukuthembeka akukhona nje ukuqhuma. Kumayelana nokuthi ivalvu iyasebenza yini uma uyidinga. UBudi ungitshele indaba ngomunye wamakhasimende akhe embonini yezolimo zasemanzini. Babesebenzisa amavalvu ebhola lethusi, kodwa amanzi anosawoti omncane abangela ukuba agqwale. Ngemva konyaka, amavalvu ayeqinile kakhulu ngenxa yokugqwala kangangokuthi ayengenakuphendulwa. Kwadingeka ashintshwe. Bashintshela kumavalvu ethu ebhola le-PVC. Eminyakeni emihlanu kamuva, lawo mavalvu e-PVC afanayo aphenduka kahle njengosuku afakwa ngalo. Lokhu ukuthembeka kwangempela kwe-PVC. Ayigqwali. Ayivalwa yizikali noma amadiphozithi amaminerali. Uma nje isetshenziswa ngaphakathi kwemingcele yayo yokucindezela/yokushisa futhi ivikelwe ku-UV, ukusebenza kwayo ngeke kwehle. Ivalvu ye-PVC esezingeni eliphezulu ebusheleleziIzihlalo ze-PTFEfuthi ethembekileAma-EPDM O-ringsinikeza izinga lokuthembeka kwesikhathi eside, okubikezelwayo okungavamile ukufana nensimbi ekusetshenzisweni kwamanzi.

Ama-ball valve alungele isikhathi esingakanani?

Uqhathanisa ivalvu ye-PVC nelethusi. Eyensimbi izwakala inzima, ngakho-ke kumelwe ukuthi ingcono, akunjalo? Lokhu kucabanga kungakuholela ekukhetheni ivalvu engalungile kulo msebenzi.

Ama-valve ebhola asebenza kahle amashumi eminyaka uma esetshenziswa kahle. Ku-PVC, lokhu kusho ukusetshenziswa kwamanzi abandayo ngaphandle kokuvezwa ngqo yi-UV. Kunsimbi, kusho amanzi ahlanzekile, angaboli.I-valve ye-PVCkuvame ukuhlala isikhathi eside kuneivalvu yensimbiezindaweni ezinolaka.

“Ilungele isikhathi esingakanani?” empeleni umbuzo othi “Ilungele ini?” Ivalvu yensimbi engagqwali ephezulu iyamangalisa, kodwa akuyona inketho enhle yechibi lokubhukuda elinamanzi ane-chlorine, elingahlasela insimbi ngokuhamba kwesikhathi. Ivalvu yethusi iyindlela enhle yokukhetha inhloso ejwayelekile, kodwa izohluleka ezinhlelweni ezinezivundisi ezithile noma amanzi ane-acidic. Yilapho i-PVC ikhanya khona. Yiyona ndlela engcono kakhulu yokusebenzisa uhla olukhulu lwezinhlelo ezisekelwe emanzini, okuhlanganisa ukuchelela, ukufuya amachibi, amachibi okubhukuda, kanye namapayipi ajwayelekile. Kulezi zimo, ngeke ibole, ngakho-ke igcina ukusebenza kwayo okubushelelezi iminyaka eminingi. Nakuba ingalungile emanzini ashisayo noma ukucindezela okuphezulu, iyinketho engcono kakhulu yendawo yayo ethile. Ivalvu ye-PVC esetshenziswe kahle izoba “ilungele” isikhathi eside kakhulu kunevalvu yensimbi esetshenziswe ngendlela engafanele. Amakhasimende aphumelela kakhulu eBudi yilawo afanisa izinto zevalvu namanzi, hhayi nje ukuqonda amandla.

Ingabe ama-ball valve ayawohloka?

Ivalvu yakho iyeke ukusebenza. Uzibuza ukuthi ivele yaguga noma kukhona okuthile okubangele ukuthi yehluleke. Ukwazi ukuthi kungani yehlulekile kuyisihluthulelo sokuyivimbela ngesikhathi esizayo.

Yebo, ama-ball valve ayawohloka ngenxa yezizathu eziningana ezicacile. Ukwehluleka okuvame kakhulu yizivalo ezigugile ngenxa yokusetshenziswa njalo, ukuwohloka kwe-UV okubangela ukuphuka, ukuhlaselwa ngamakhemikhali ezintweni, noma umonakalo ongokwenyama ngenxa yokushaywa noma ukuqina ngokweqile.

Ama-valve ebhola awagcini nje ngokuyeka ukusebenza ngenxa yokuguga; ingxenye ethile iyahluleka. Indawo evame kakhulu yokuhluleka yizivalo zangaphakathi. Izihlalo ze-PTFE ezivala ibhola zingaguga ngemva kwezinkulungwane zemijikelezo evulekile/evaliwe, okuholela ekuvuzeni okuncane. Ama-EPDM O-rings esiqwini nawo angaguga, okubangela ukuvuza esibambweni. Lokhu kungukuguguleka okuvamile. Imbangela yesibili enkulu umonakalo wemvelo. Njengoba sixoxile, ukukhanya kwe-UV kuyabulala, okwenza umzimba we-valve ube buthaka. Ikhemikhali engalungile ingenza i-PVC ibe thambile noma ibhubhise ama-O-rings. Indlela yesithathu ehamba kabi ngayo ukufakwa okungafanele. Iphutha elivame kakhulu engilibonayo ukuthi abantu baqinisa ama-valve e-PVC anezintambo ngokweqile. Basonga i-thread tape eningi kakhulu bese besebenzisa i-wrench enkulu, engaphula umzimba we-valve khona kanye lapho kuxhumaniswa khona. Ukuqonda lezi zindlela zokuhluleka kukusiza ukuvikela utshalomali lwakho futhi uqinisekise ukuthi luhlala isikhathi eside.

Isiphetho

Ivalvu ye-PVC esezingeni eliphezulu ingahlala amashumi eminyaka. Isikhathi sayo sokuphila sincike kakhulu esikhathini kodwa sincike kakhulu ekusetshenzisweni okufanele, ekuvikelweni ekukhanyeni kwe-UV, kanye nomklamo wesistimu ofanele wokusetshenziswa kwayo.
