Ufake ivalve entsha yePVC kwaye ulindele ukuba isebenze iminyaka. Kodwa ukusilela ngequbuliso kunokubangela umkhukula, konakalise izixhobo, kwaye kuvalwe imisebenzi.

Ivalve yebhola yePVC ekumgangatho ophezulu ingahlala ukuya kuthi ga kwiminyaka engama-20 kwiimeko ezifanelekileyo. Nangona kunjalo, ubomi bayo bokwenyani bumiselwa yimiba efana nokuvezwa kwe-UV, ukunxibelelana neekhemikhali, ubushushu bamanzi, uxinzelelo lwenkqubo, kunye nokuba isetyenziswa kangaphi.

Elo nani leminyaka engama-20 lisiqalo, ayisosiqinisekiso. Impendulo yokwenyani ithi "kuxhomekeke." Bendithetha ngale nto noBudi, umphathi wokuthenga endisebenza naye eIndonesia. Ubona i-spectrum epheleleyo. Abanye abathengi bayeiivalve zethuukusebenza ngokugqibeleleyo kwiinkqubo zezolimo emva kweminyaka eli-15. Abanye baye baphelelwa ziivalvu ngaphantsi kweminyaka emibini. Umahluko asilovalvu ngokwayo, kodwa yindawo ehlala kuyo. Ukuqonda ezi meko zokusingqongileyo kuphela kwendlela yokuqikelela ukuba ivalve yakho iya kuhlala ixesha elingakanani kwaye uqiniseke ukuba ifikelela kwisakhono sayo esipheleleyo.

Yintoni ubude bobomi bevalve yebhola yePVC?

Ufuna inombolo elula yesicwangciso sakho seprojekthi. Kodwa ukusekela umda wexesha kunye nohlahlo lwabiwo-mali kuqikelelo kuyingozi, ngakumbi ukuba ivalve isilela ixesha elide ngaphambi kokuba uyilindele.

Ubomi obulindelekileyo bevalve yebhola yePVC busukela kwiminyaka embalwa ukuya ngaphezulu kwamashumi amabini eminyaka. Ayilungiswanga le nto. Ubomi buxhomekeke ngokupheleleyo kwindawo yayo yokusebenza kunye nomgangatho wezinto zayo.

Cinga ngobomi bevalve njengoqingqo-mali. Iqala kwiminyaka engama-20, kwaye zonke iimeko ezinzima "zichitha" ezinye zobo bomi ngokukhawuleza. Eyona nkcitho inkulu kukukhanya kwelanga kwe-UV kunye nokusetyenziswa rhoqo. Ivalve evulwayo yaze ivalwe amakhulu amaxesha ngemini iya kuguga amatywina ayo angaphakathi ngokukhawuleza kunaleyo ijikwa kanye ngenyanga. Ngokunjalo, ivalve efakwe ngaphandle ekukhanyeni kwelanga iya kuba brittle kwaye ibe buthathaka ngokuhamba kwexesha. Imitha ye-UV ihlasela iibhondi zemolekyuli kwiPVC. Emva kweminyaka embalwa, inokuba buthathaka kangangokuba ukunkqonkqozwa nje okungephi kunokuyiqhekeza. Ukuhambelana nemichiza, amaqondo obushushu aphezulu, noxinzelelo olugqithisileyo nazo ziyabunciphisa ubomi bayo. Aumgangatho wevalveeyenziwe kwi-100% ye-PVC enyulu enezihlalo ze-PTFE ezomeleleyo ziya kuhlala ixesha elide kunevalve enexabiso eliphantsi elinezihluzi, kodwa nevalve engcono kakhulu iya kusilela kwangoko ukuba isetyenziswe kwiimeko ezingalunganga.

Izinto eziNciphisa i-PVC yeValve Lifespan

Zithembeke kangakanani iivalvu zebhola zePVC?

I-PVC ibonakala njengeplastiki, kwaye iplastiki inokuziva ibuthathaka. Unexhala lokuba inokwaphuka okanye ivuze phantsi koxinzelelo, ngakumbi xa ithelekiswa nevalve yentsimbi enzima.

Iivalvu zebhola zePVC ezikumgangatho ophezulu zithembeke kakhulu kwizicelo ezijolise kuzo. Ukwakhiwa kweplastiki yabo kuthetha ukuba bakhuselekile ngokupheleleyo kwi-rust kunye ne-mineral buildup ebangela ukuba iivalve zentsimbi zingaphumeleli okanye zibambe ngokuhamba kwexesha.

Ukuthembeka akukhona nje ngokugqabhuka. Imalunga nokuba ivalve isebenza xa uyifuna. UBudi undixelele ibali ngomnye wabathengi bakhe kwishishini leaquaculture. Babedla ngokusebenzisa izivalo zebhola yobhedu, kodwa amanzi anetyuwa kancinane abangela ukuba zidle. Emva konyaka, iivalve zaziqinile kangangokuba zazingakwazi ukujikwa. Kwafuneka kutshintshwe. Batshintshela kwiivalvu zethu zebhola zePVC. Kwiminyaka emihlanu kamva, kwa ezo zivalo zePVC zinye zijika ngokutyibilikayo njengosuku ezafakwa ngalo. Oku kukuthembeka kokwenyani kwePVC. Ayirhaleli. Ayivaleki sisikali okanye iidipozithi zeminerali. Logama nje isetyenziswa ngaphakathi kwemida yoxinzelelo / lobushushu kwaye ikhuselwe kwi-UV, ukusebenza kwayo akuyi kuthotywa. Ivalve yePVC esemgangathweni egudileyoIzihlalo ze-PTFEkwaye inokuthenjwaEPDM O-amakhonkcoinikeza inqanaba lexesha elide, ukuthembeka okuqikelelwayo ukuba isinyithi kaninzi asikwazi ukuhambelana kwizicelo zamanzi.

Zilungele ixesha elingakanani iivalvu zebhola?

Uthelekisa ivalve yePVC neyebhedu. Intsimbi ivakala inzima, ngoko ke kufuneka ibengcono, akunjalo? Le ngcinga inokukhokelela ekubeni ukhethe ivalve engalunganga yomsebenzi.

Iivalvu zebhola zilungile amashumi eminyaka xa zisetyenziswa ngokuchanekileyo. Kwi-PVC, oku kuthetha ukufakwa kwamanzi abandayo ngaphandle kokuvezwa ngokuthe ngqo kwe-UV. Kwisinyithi, kuthetha ukuba amanzi acocekileyo, angenakonakala. AIvalve yePVCihlala iphuma aivalve yesinyithikwiindawo ezinobundlobongela.

"Kude kube nini?" ngokwenene ngumbuzo othi "Ilungele ntoni?" I-valve yebhola yensimbi engenasiphelo ephezulu iyamangalisa, kodwa ayisiyonto ilungileyo yokukhetha indawo yokuqubha enamanzi aneklorini, enokuhlasela isinyithi ngokuhamba kwexesha. Ivalve yobhedu lukhetho olukhulu lwenjongo jikelele, kodwa iya kusilela kwiinkqubo ezinezichumisi ezithile okanye amanzi aneasidi. Kulapho iPVC ikhanya khona. Lolona khetho lubalaseleyo kuluhlu olukhulu lwezicelo ezisekelwe emanzini, kubandakanywa ukunkcenkceshela, i-aquaculture, amachibi kunye nemibhobho jikelele. Kwezi ndawo, ayizukonakala, ngoko igcina ukusebenza kwayo kakuhle iminyaka. Nangona ingalunganga kumanzi ashushu okanye uxinzelelo oluphezulu, lukhetho oluphezulu kwi-niche yayo ethile. Ivalve ye-PVC esetyenziswe ngokuchanekileyo iya kuba "ilungele" ixesha elide kunevalve yentsimbi esetyenziswe ngokungalunganga. Abona bathengi baphumeleleyo bakaBudi ngabo bafanisa imathiriyeli yevalvu emanzini, hayi nje ukuqonda amandla.

Ngaba iivalve zebhola zihamba kakubi?

Ivalve yakho iyekile ukusebenza. Uyazibuza ukuba iphelile na okanye kukho into ethile ebangele ukuba isilele. Ukwazi ukuba kutheni isilele sisitshixo sokuyithintela kwixesha elizayo.

Ewe, iivalve zebhola zihamba kakubi ngenxa yezizathu ezininzi ezicacileyo. Ezona ntsilelo zixhaphakileyo zizitywina ezigugileyo ezivela kusetyenziso rhoqo, ukuthotywa kwe-UV okubangela ukonakala, uhlaselo lweekhemikhali kwizinto ezisetyenziswayo, okanye umonakalo womzimba ngenxa yempembelelo okanye ukuqina.

Izivalo zebhola aziyeki nje ukusebenza ngenxa yobudala; inxalenye ethile iyasilela. Eyona nto ixhaphakileyo yokungaphumeleli ngamatywina angaphakathi. Izihlalo ze-PTFE ezitywina ngokuchasene nebhola zinokuguga emva kwamawaka emijikelo evulekileyo/evaliweyo, ekhokelela ekuvuzeni okuncinci. I-EPDM O-rings kwi-stem nayo inokuguga, ibangele ukuvuza kwi-handle. Oku kunxitywa kunye nokukrazuka okuqhelekileyo. Unobangela wesibini omkhulu kukonakala kwendalo. Njengoko besixoxile, ukukhanya kwe-UV ngumbulali, okwenza umzimba wevalve ube brittle. Ikhemikhali engafanelekanga inokuguqula i-PVC ithambile okanye itshabalalise i-O-rings. Indlela yesithathu abahamba ngayo kukufakela okungafanelekanga. Eyona mpazamo ixhaphakileyo ndiyibonayo ngabantu baqinisa kakhulu iivalvu zePVC ezinemisonto. Basonga iteyiphu yentambo eninzi kakhulu kwaye emva koko basebenzise isikrufu esikhulu, esinokukrazula umzimba wevalvu kanye ekudibaneni. Ukuqonda ezi ndlela zokungaphumeleli kukunceda ukhusele utyalo-mali lwakho kwaye uqinisekise ukuba luhlala luhleli.

Ukuqukumbela

Ivalve yePVC esemgangathweni ingahlala amashumi eminyaka. Ubomi bayo buxhomekeke kancinci kwixesha nangaphezulu ekusebenziseni ngokufanelekileyo, ukukhuselwa kwisibane se-UV, kunye noyilo lwenkqubo oluchanekileyo lokusetyenziswa kwayo.
