Udizayina isistimu futhi udinga ukwethemba izingxenye zakho. I-valve ehlulekile ingasho isikhathi sokuphumula esibizayo kanye nokulungiswa, kukwenze ubuze ukuthi leyo ngxenye ye-PVC ethengekayo bekufanele yini.

Ivalvu yebhola ye-PVC yekhwalithi ephezulu, eyenziwe ngezinto ezingasetshenziswanga futhi yasetshenziswa ngendlela efanele, ingahlala kalula iminyaka eyi-10 kuye kwengama-20, futhi ngokuvamile kuyo yonke impilo yesistimu yamapayipi efakwe kuyo. Ubude bayo buncike kukhwalithi, isicelo, nendawo.

Lo mbuzo usenhliziyweni yalokho esikwenzayo. Ngikhumbula ingxoxo no-Budi, uzakwethu oyinhloko wokusabalalisa e-Indonesia. Elinye lamakhasimende akhe, umfelandawonye omkhulu wezolimo, lalingabaza ukusebenzisa eyethuAma-valve e-PVC. Ayejwayele ukushintsha amavalvu ensimbi agqwalile njalo ngemva kweminyaka embalwa futhi ayengakholwa ukuthi ivalvu “yepulasitiki” yayizohlala isikhathi eside. UBudi wabaqinisekisa ukuthi bazame abambalwa emigqeni yabo yokunisela enzima kakhulu ngomanyolo. Lokho kwenzeka eminyakeni eyisikhombisa edlule. Ngingene naye ngenyanga edlule, wangitshela ukuthi lawo mavalvu afana ncamashi asasebenza kahle. Abakashintshi nelilodwa. Yilokho umehluko wekhwalithi ewenzayo.

Ingakanani iminyaka yokuphila ye-valve yebhola ye-PVC?

Udinga ukuhlela izindleko zesondlo kanye nokushintsha. Ukusebenzisa ingxenye enobude bempilo obungaziwa kwenza ibhajethi yakho ibe ukuqagela okuphelele futhi kungaholela ekuhlulekeni okungalindelekile emgwaqeni.

Impilo yesevisi elindelekile yevalvu yebhola ye-PVC yekhwalithi ngokuvamile iyiminyaka eyi-10 kuye kwengama-20. Nokho, ezimweni ezikahle—amanzi asendlini, abandayo, ukusetshenziswa njalo—kungahlala isikhathi eside. Okuguquguqukayo okubalulekile ikhwalithi yezinto ezibonakalayo, ukuchayeka kwe-UV, kanye nengcindezi yokusebenza.

Ukuphila kwe-valve akuyona inombolo eyodwa; kuwumphumela wezici eziningana ezibalulekile. Okubaluleke kakhulu yimpahla eluhlaza. Kwa-Pntek, sisebenzisa kuphela inhlaka ye-PVC emsulwa engu-100%. Lokhu kuqinisekisa amandla aphezulu kanye nokumelana namakhemikhali. Ama-valve ashibhile avame ukusetshenziswa"regrind" (i-PVC egaywe kabusha), okungaba brittle futhi okungalindelekile. Esinye isici esikhulu ukuchayeka kwe-UV kusuka elangeni. I-PVC evamile ingaba ntekenteke ngokuhamba kwesikhathi uma ishiywe elangeni, yingakho sinikeza amamodeli athile amelana ne-UV ezisetshenziswa zangaphandle njengokunisela. Ekugcineni, cabanga ngezimvu zamanzi. Sisebenzisa izihlalo eziqinile ze-PTFE ezihlinzeka ngophawu olubushelelezi, oluqinile olumelana nezinkulungwane zamajika. Amavalvu ashibhile anezivalo zenjoloba ezijwayelekile azoguga ngokushesha okukhulu. Ukutshala imali kwikhwalithi kusengaphambili kuyindlela eqinisekile yokuqinisekisa impilo ende.

Izici Eziyinhloko Ezinquma Ubude Besikhathi Sokuphila

Athembeke kangakanani ama-valve ebhola e-PVC?

Udinga ingxenye ongayifaka futhi ukhohlwe ngayo. I-valve engathembekile isho ukukhathazeka njalo mayelana nokuvuza okungase kube khona, ukuvalwa kwesistimu, nokulungiswa okungcolile, okubizayo. Kuyingozi ongeke ukwazi ukuyikhokhela.

Ngenhloso yawo yokulawula ukugeleza kwamanzi abandayo,ama-valve ebhola e-PVC aphezuluzithembeke ngokwedlulele. Ukuthembeka kwabo kuvela ekwakhiweni okulula okunezingxenye ezimbalwa ezihambayo kanye nezinto ezibonakalayo ezingavikeleki ngokuphelele ekugqwaleni nokugqwala.

Ukuthembeka kwe-valve kumayelana nekhono layo lokumelana nokwehluleka okuvamile. Yilapho i-PVC ikhanya khona ngempela. Ngihlale ngitshela uBudi ukuthi achazele amakhasimende akhe asebenza eduze nogu ngalokhu. Amavalvu ensimbi, ngisho nalawo ethusi, ekugcineni azogqwala emoyeni onosawoti, onomswakama. I-PVC ngeke nje. Ayikwazi ukugqwala kanye nokugqwala kwamakhemikhali amaningi atholakala ezinhlelweni zamanzi. Omunye umthombo wokwethenjelwa ukuklama. Amavalvu amaningi ashibhile asebenzisa i-O-ring eyodwa esiqwini ukuvimbela ukuvuza esibambo. Leli yiphuzu lokuhluleka elidume kabi. Saklama eyethu ngama-O-rings akabili. Kuwushintsho oluncane, kodwa kunikeza uphawu olungasasebenzi okwandisa ngokuphawulekayo ukwethembeka kwesikhathi eside ngokumelene namadriphu okubamba. Indlela elula yokuguqula ikota kanye nomzimba oqinile, ongagqwali kwenza ivalvu yekhwalithi ye-PVC ibe enye yezingxenye ezithembeke kakhulu kunoma iyiphi isistimu yamanzi.

Kuvelaphi Ukwethembeka?

Ama-valve ebhola kufanele ashintshwe kangaki?

Udinga uhlelo lokulungisa uhlelo lwakho. Kodwa ukususa ngokuqhubekayo izingxenye ezingaphukile kuwukumosha imali, kuyilapho ukulinda isikhathi eside kungaholela ekuhlulekeni okuyinhlekelele.

Ama-valve ebhola awanalo uhlelo olungaguquki lokushintsha. Kufanele zishintshwe ngombandela, hhayi ngesibali sikhathi. Ngevalvu yekhwalithi ephezulu kusistimu ehlanzekile, lokhu kungase kusho ukuthi ayidingi ukushintshwa phakathi nesikhathi sokuphila sohlelo.

Esikhundleni sokucabanga ngeshejuli, kungcono ukwazi izimpawu ze-valve eqala ukwehluleka. Siqeqesha ithimba likaBudi ukuthi lifundise amakhasimende “ukubheka, ukulalela, nokuzwa.” Uphawu oluvame kakhulu ukuthi isibambo siqine kakhulu noma sibe nzima ukusijika. Lokhu kungasho ukwakheka kwamaminerali noma ukufaka uphawu ngaphakathi. Olunye uphawu yinoma yikuphi ukukhala noma ukuconsa kusuka eduze kwesiqu sesibambo, okubonisa ukuthi ama-O-ring awaphumeleli. Uma uvala i-valve futhi amanzi asageleza, ibhola langaphakathi noma izihlalo cishe ziklwebhekile noma zilimale. Lokhu kungenzeka uma usebenzisa i-valve yebhola ukunyakazisa ukugeleza esikhundleni sokulawula okulula kokuvula/ukuvala. Ngaphandle uma ivalvu ikhombisa eyodwa yalezi zimpawu, asikho isizathu sokuyishintsha. Ivalvu yekhwalithi yakhelwe ukuthi ihlale isikhathi eside, ngakho-ke udinga kuphela ukuthatha isinyathelo uma ikutshela ukuthi kunenkinga.

Isayina Ivalvu Yebhola Idinga Ukushintshwa

Ingabe i-valve yokuhlola i-PVC ingahamba kabi?

Une-valve yokuhlola evimbela ukugeleza emuva, kodwa ifihliwe phansi komugqa wepompo. Ukwehluleka kungase kungabonakali kuze kube yilapho iphampu yakho ilahlekelwa amanzi abalulekile noma angcolile ageleza emuva.

Yebo, aI-valve yokuhlola ye-PVCnakanjani ingahamba kabi. Ukwehluleka okuvamile kufaka phakathi uphawu lwangaphakathi olugugayo, ihinge ekuqhekekeni kwevalvu yokushwibeka, noma ingxenye enyakazayo egcwele udoti, okuyenza yehluleke.

Nakuba sigxile kuma-valve ebhola, lona umbuzo omuhle ngoba ama-valve okuhlola nawo abaluleke kakhulu. Bayingxenye "yokuyibeka futhi uyikhohlwe", kodwa banezingxenye ezihambayo ezingaguga. Ukwehluleka okuvame kakhulu ku-ai-valve yokuhlola isitayela sokujikai-flap ayivali kahle ngokumelene nesihlalo. Lokhu kungaba ngenxa yophawu lwenjoloba egugile noma imfucumfucu encane njengesihlabathi esibanjwa kuyo. Kuma-valve okuhlola alayishwe entwasahlobo, isiphethu sensimbi ngokwaso singagcina sigqwalile noma sikhathale, sibangele ukuba siphuke. Umzimba we-valve, njenge-valve yebhola, uqinile kakhulu ngoba wenziwe nge-PVC. Kodwa izingxenye zangaphakathi zemishini zingamaphuzu abuthakathaka. Yingakho ukuthenga i-valve yokuhlola ikhwalithi kubaluleke kakhulu. Eklanywe kahle enophawu oluqinile kanye ne-hinge eqinile izohlinzeka ngeminyaka eminingi yesevisi enokwethenjelwa futhi ivikele isistimu yakho ekugelezeni emuva.

Isiphetho

I-valve yebhola ye-PVC yekhwalithi ephezulu ingahlala amashumi eminyaka, ngokuvamile impilo yonke yesistimu. Zishintshe ngokusekelwe esimweni, hhayi ishejuli, futhi zizohlinzeka ngesevisi ehlukile, ethembekile.
