Ufake ivalvu entsha yebhola yePVC kwaye ulindele ukuba isebenze iminyaka. Kodwa ukusilela ngequbuliso kunokubangela izikhukula, konakalise izixhobo, kwaye kumise imisebenzi.

Ivalvu yebhola yePVC esemgangathweni ophezulu inokuhlala iminyaka engama-20 kwiimeko ezifanelekileyo. Nangona kunjalo, ubomi bayo bokwenyani buxhomekeke kwizinto ezifana nokuvezwa yi-UV, ukudibana kweekhemikhali, ubushushu bamanzi, uxinzelelo lwenkqubo, kunye nokuba isetyenziswa kangaphi.

Elo nani leminyaka engama-20 lisiqalo, hayi isiqinisekiso. Impendulo yokwenyani ithi “kuxhomekeke.” Bendithetha ngale nto noBudi, umphathi wokuthenga endisebenza naye eIndonesia. Uyabona yonke into. Abanye abathengi banayoiivalvu zethuisebenza ngokugqibeleleyo kwiinkqubo zezolimo emva kweminyaka eli-15. Abanye baye baphulukana neevalvu ngaphantsi kweminyaka emibini. Umahluko awukho kwivalvu ngokwayo, kodwa yindawo ehlala kuyo. Ukuqonda ezi zinto zendalo yindlela ekuphela kwayo yokuqikelela ukuba ivalvu yakho iya kuhlala ixesha elingakanani kwaye uqinisekise ukuba ifikelela kwisakhono sayo esipheleleyo.

Ingakanani ixesha lokuphila kwevalvu yebhola yePVC?

Ufuna inombolo elula yesicwangciso sakho seprojekthi. Kodwa ukusekela ixesha lakho kunye nohlahlo-lwabiwo mali kuqikelelo kuyingozi, ingakumbi ukuba ivalvu iyasilela kudala ngaphambi kokuba ulindele.

Ixesha lokuphila kwevalvu yebhola yePVC liqala kwiminyaka embalwa ukuya kwiminyaka engamashumi amabini. Oku akukamiselwanga. Ixesha lokuphila lixhomekeke ngokupheleleyo kwindawo yokusebenza kwayo kunye nomgangatho wezinto zayo.

Cinga ngobomi bevalvu njengohlahlo-lwabiwo mali. Iqala xa ineminyaka engama-20, kwaye yonke imeko enzima "ichitha" inxalenye yaloo bomi ngokukhawuleza. Eyona ichitha kakhulu kukukhanya kwelanga kwe-UV kunye nokusetyenziswa rhoqo. Ivalvu evulwa kwaye ivalwe amaxesha amaninzi ngemini iya kuguga izitywino zayo zangaphakathi ngokukhawuleza kakhulu kuneyo ijikwa kube kanye ngenyanga. Ngokufanayo, ivalvu efakwe ngaphandle elangeni ngqo iya kuba buthathaka kwaye ibe buthathaka ngokuhamba kwexesha. Imitha ye-UV ihlasela iibhondi zemolekyuli kwi-PVC. Emva kweminyaka embalwa, inokuba buthathaka kangangokuba ukungqubana okuncinci kunokuyiphula. Ukuhambelana kweekhemikhali, amaqondo obushushu aphezulu, kunye noxinzelelo olugqithisileyo nako kunciphisa ubomi bayo.ivalvu esemgangathweniyenziwe nge-PVC eyi-100% emsulwa enezihlalo ze-PTFE eziqinileyo iya kuhlala ixesha elide kunevalvu engabizi kakhulu enezizalisi, kodwa nevalvu engcono kakhulu iya kusilela kwangethuba ukuba isetyenziswe kwiimeko ezingalunganga.

Izinto Ezinciphisa Ubomi beValve yePVC

Zithembeke kangakanani iivalvu zebhola zePVC?

I-PVC ifana neplastiki, kwaye iplastiki ingaziva ibuthathaka. Uxhalabile ukuba ingaphuka okanye ivuze xa iphantsi koxinzelelo, ingakumbi xa ithelekiswa nevalvu yesinyithi esinzima.

Iivalvu zebhola zePVC ezikumgangatho ophezulu zithembeke kakhulu kwiindlela ezicetywayo. Ukwakhiwa kwazo ngeplastiki kuthetha ukuba azinawo umhlwa kunye nokwakheka kweeminerali okubangela ukuba iivalvu zesinyithi zingasebenzi okanye zibambeke ngokuhamba kwexesha.

Ukuthembeka akupheleli nje ekuqhumeni. Kumalunga nokuba ivalvu isebenza na xa uyidinga. UBudi undixelele ibali ngomnye wabathengi bakhe kwishishini lezolimo zasemanzini. Babesebenzisa iivalvu zebhola yobhedu, kodwa amanzi anetyuwa encinci abangele ukuba zibole. Emva konyaka, iivalvu zaziqinile ngenxa yokubola kangangokuba zazingenakujikwa. Kwafuneka zitshintshwe. Batshintshela kwiivalvu zethu zebhola zePVC. Kwiminyaka emihlanu kamva, ezo valve zePVC zijikeka kakuhle njengangomhla ezafakwa ngawo. Oku kukuthembeka kokwenyani kwePVC. Ayigqwali. Ayivalwa zizikali okanye iidiphozithi zezimbiwa. Lo gama nje isetyenziswa ngaphakathi kwemida yayo yoxinzelelo/ubushushu kwaye ikhuselwe kwi-UV, ukusebenza kwayo akuyi kuncipha. Ivalvu yePVC esemgangathweni ethambileyoIzihlalo ze-PTFEkwaye ithembekileIiringi ze-EPDM Oinika inqanaba lokuthembeka kwexesha elide, eliqikelelwayo elingenakufanekiswa nentsimbi kwiindawo zamanzi.

Iivalvu zebhola zilungele ixesha elingakanani?

Uthelekisa ivalvu yePVC neyethusi. Eyesinyithi ivakala inzima, ngoko ke kufuneka ukuba ingcono, akunjalo? Le ngcinga inokukhokelela ekubeni ukhethe ivalvu engalunganga kulo msebenzi.

Iivalvu zebhola zilungile amashumi eminyaka xa zisetyenziswa ngokuchanekileyo. Kwi-PVC, oku kuthetha ukusetyenziswa kwamanzi abandayo ngaphandle kokuvezwa ngqo kwi-UV. Kwisinyithi, kuthetha amanzi acocekileyo, angaboliyo.ivalvu yePVCihlala ixesha elide kuneivalvu yesinyithikwiindawo ezinobundlobongela.

“Ilungele ixesha elingakanani?” ngumbuzo wokuba “Ilungele ntoni?” Ivalvu yebhola yentsimbi engagqwaliyo ephezulu iyamangalisa, kodwa ayilokhetho lulungileyo kwidama lokudada elinamanzi ane-chlorine, anokuhlasela isinyithi ngokuhamba kwexesha. Ivalvu yobhedu lukhetho oluhle kakhulu oluqhelekileyo, kodwa iya kusilela kwiinkqubo ezinezichumisi ezithile okanye amanzi ane-asidi. Kulapho iPVC ikhanya khona. Lukhetho olulungileyo kuluhlu olukhulu lwezicelo ezisekelwe emanzini, kubandakanya ukunkcenkceshela, ukulima amachibi, amachibi, kunye nemibhobho ngokubanzi. Kule meko, ayizukubola, ngoko igcina ukusebenza kwayo kakuhle iminyaka. Nangona ingalunganga kumanzi ashushu okanye uxinzelelo oluphezulu, lukhetho oluphezulu kwindawo yayo ethile. Ivalvu yePVC esetyenziswe ngokuchanekileyo iya kuba “lungile” ixesha elide kakhulu kunevalvu yesinyithi esetyenziswe gwenxa. Abathengi abaphumeleleyo kakhulu beBudi ngabo bafanisa izinto zevalvu namanzi, kungekuphela nje ekuqondeni amandla.

Ngaba iivalvu zebhola ziyawohloka?

Ivalvu yakho iyekile ukusebenza. Uzibuza ukuba ingaba igugile okanye kukho into ethile ebangele ukuba ingasebenzi. Ukwazi isizathu sokuba ingasebenzi yeyona nto ibalulekileyo ekuthinteleni ukuba ingasebenzi kwixesha elizayo.

Ewe, iivalvu zebhola ziyawohloka ngenxa yezizathu ezininzi ezicacileyo. Ezona ngxaki zixhaphakileyo zizitywino ezigugileyo ngenxa yokusetyenziswa rhoqo, ukonakala kwe-UV okubangela ukuqhekeka, ukuhlaselwa ziikhemikhali kwizinto, okanye umonakalo womzimba ngenxa yokutsha okanye ukuqina kakhulu.

Iivalvu zebhola aziyeki nje ukusebenza ngenxa yobudala; inxalenye ethile iyasilela. Eyona ndawo ixhaphakileyo yokusilela ziiseal zangaphakathi. Izitulo zePTFE ezivala ibhola zinokuguga emva kwamawaka eemijikelo ezivulekileyo/ezivaliweyo, nto leyo ekhokelela ekuvutheni okuncinci. Iiringi ze-EPDM O ezikwisiqu nazo zinokuguga, zibangele ukuvuza esiphandeni. Oku kukuguga okuqhelekileyo. Isizathu sesibini esikhulu kukonakala kwendalo. Njengoko sixoxile, ukukhanya kwe-UV kuyabulala, okwenza umzimba wevalvu ube buthathaka. Ikhemikhali engalunganga ingenza iPVC ithambe okanye itshabalalise iiringi ze-O. Indlela yesithathu ezihamba ngayo kakubi kukufakelwa okungafanelekanga. Eyona mpazamo ixhaphakileyo endiyibonayo kukuba abantu baqinisa iivalvu zePVC ezinemisonto kakhulu. Basonga iteyiphu yemisonto emininzi kakhulu baze basebenzise isikrufu esikhulu, esinokuqhekeza umzimba wevalvu kanye kwindawo eqhagamshelweyo. Ukuqonda ezi ndlela zokusilela kukunceda ukhusele utyalo-mali lwakho kwaye uqinisekise ukuba luhlala luhleli.

Isiphelo

Ivalvu yePVC esemgangathweni inokuhlala amashumi eminyaka. Ubomi bayo buxhomekeke kancinci kwixesha kodwa buxhomekeke kakhulu ekusetyenzisweni ngokufanelekileyo, ukhuseleko ekukhanyeni kwe-UV, kunye noyilo olufanelekileyo lwenkqubo yokusetyenziswa kwayo.
