Uklama uhlelo futhi udinga ukwethemba izingxenye zakho. I-valve ehlulekile ingasho isikhathi sokungasebenzi kanye nokulungiswa okubizayo, okukwenza uzibuze ukuthi leyo ngxenye ye-PVC engabizi yayikufanele yini.

Ivalvu yebhola ye-PVC esezingeni eliphezulu, eyenziwe ngezinto ezingasetshenziswanga futhi isetshenziswe kahle, ingahlala iminyaka eyi-10 kuya kwengama-20 kalula, futhi ngokuvamile impilo yonke yesistimu yamapayipi efakwe kuyo. Ukuphila kwayo isikhathi eside kuncike kwikhwalithi, ukusetshenziswa, kanye nendawo ezungezile.

Lo mbuzo uyisisekelo salokho esikwenzayo. Ngikhumbula ingxoxo noBudi, umlingani wethu obalulekile wokusabalalisa e-Indonesia. Omunye wamakhasimende akhe, inhlangano enkulu yezolimo, wayenqikaza ukusebenzisa i-Amavalvu e-PVC. Babejwayele ukushintsha amavalvu abo ensimbi agqwalile njalo eminyakeni embalwa futhi babengakholwa ukuthi ivalvu “yepulasitiki” izohlala isikhathi eside. UBudi wabancenga ukuthi bazame ambalwa emigqeni yabo yokunisela eningi kakhulu ngomanyolo. Lokho kwakuyiminyaka eyisikhombisa edlule. Ngaxhumana naye ngenyanga edlule, wangitshela ukuthi lawo mavalvu afanayo asasebenza kahle. Awakashintshi nelilodwa. Yilowo umehluko owenziwa yikhwalithi.

Iyini isikhathi sokuphila sevalvu yebhola le-PVC?

Udinga ukuhlela izindleko zokulungisa nokufaka esikhundleni. Ukusebenzisa ingxenye ehlala isikhathi eside engaziwa kwenza isabelomali sakho sibe ukuqagela okuphelele futhi kungaholela ekuhlulekeni okungalindelekile kamuva.

Impilo yesevisi elindelekile yevalvu yebhola ye-PVC esezingeni eliphezulu ivame ukuba yiminyaka eyi-10 kuya kwengama-20. Kodwa-ke, ezimweni ezinhle kakhulu—endlini, emanzini abandayo, ekusetshenzisweni okungajwayelekile—ingahlala isikhathi eside kakhulu. Izinto ezibalulekile yikhwalithi yezinto ezibonakalayo, ukuchayeka ku-UV, kanye nokucindezeleka kokusebenza.

Isikhathi sokuphila kwevalvu akuyona inombolo eyodwa; kungumphumela wezici eziningana ezibalulekile. Okubaluleke kakhulu yizinto zokusetshenziswa. Kwa-Pntek, sisebenzisa kuphela i-resin ye-PVC engu-100% virgin. Lokhu kuqinisekisa amandla aphezulu kanye nokumelana namakhemikhali. Amavalvu ashibhile avame ukusebenzisa“phinda ugaye” (i-PVC ephinde yasetshenziswa), okungaba buthakathaka futhi kungabikezeleki. Esinye isici esikhulu ukuchayeka elangeni ngenxa ye-UV. I-PVC ejwayelekile ingaba buthakathaka ngokuhamba kwesikhathi uma ishiywa elangeni, yingakho sinikeza amamodeli athile amelana ne-UV okusetshenziswa ngaphandle njengokunisela. Okokugcina, cabanga ngezimbobo. Sisebenzisa izihlalo ze-PTFE eziqinile ezihlinzeka ngesimbobo esibushelelezi, esingashisi kakhulu esimelana nezinkulungwane zokujika. Amavalvu ashibhile anezimbobo zerabha ezijwayelekile azoguga ngokushesha okukhulu. Ukutshala imali ekhwalithini kusengaphambili kuyindlela eqinisekile yokuqinisekisa impilo ende.

Izici Eziyinhloko Ezinquma Isikhathi Sokuphila

Ama-valve ebhola e-PVC athembeke kangakanani?

Udinga ingxenye ongayifaka bese uyikhohlwa. Ivalvu engathembekile isho ukukhathazeka njalo ngokuvuza okungenzeka, ukuvalwa kwesistimu, kanye nokulungiswa okubizayo nokungcolile. Kuyingozi ongeke ukwazi ukuyikhokhela.

Ngenhloso yabo yokulawula ukugeleza kwamanzi abandayo,ama-valve ebhola e-PVC asezingeni eliphezuluzithembeke kakhulu. Ukuthembeka kwazo kuvela ekwakhiweni okulula okunezingxenye ezimbalwa ezihambayo nezinto ezingavikeleki ngokuphelele ekugqwaleni nasekugqwaleni.

Ukuthembeka kwevalvu kumayelana nekhono layo lokumelana nokwehluleka okuvamile. Yilapho i-PVC ikhanya khona ngempela. Ngihlala ngitshela uBudi ukuthi achazele amakhasimende akhe asebenza eduze nogu. Amavalvu ensimbi, ngisho nawethusi, azogcina egqwalile emoyeni onosawoti nomswakama. I-PVC ngeke igqwale. Ayikwazi ukugqwala kanye nokugqwala kwamakhemikhali amaningi atholakala ezinhlelweni zamanzi. Omunye umthombo wokuthembeka ukwakheka. Amavalvu amaningi ashibhile asebenzisa indandatho eyodwa ye-O esiqwini ukuvimbela ukuvuza esibambweni. Lena indawo yokwehluleka eyaziwayo. Saklama eyethu ngama-O-rings amabili. Kungushintsho oluncane, kodwa lunikeza uphawu oluphindaphindayo olukhulisa kakhulu ukuthembeka kwesikhathi eside ngokumelene nokuconsa kwezibambo. Indlela elula yokujika kwekota kanye nomzimba oqinile, ongagqwali kwenza ivalvu ye-PVC esezingeni eliphezulu ibe enye yezingxenye ezithembeke kakhulu kunoma yiluphi uhlelo lwamanzi.

Ukuthembeka Kuvelaphi?

Ama-ball valve kufanele ashintshwe kangaki?

Udinga uhlelo lokulungisa uhlelo lwakho. Kodwa ukufaka ezinye izingxenye ezingaphukile ngokuzikhandla kuwukuchitha imali, kanti ukulinda isikhathi eside kakhulu kungaholela ekwehlulekeni okukhulu.

Amavalvu ebhola awanaso isimiso sokushintsha esinqunyiwe. Kufanele ashintshwe ngombandela, hhayi ngesibali sikhathi. Kuvalvu esezingeni eliphezulu ohlelweni oluhlanzekile, lokhu kungasho ukuthi akudingeki ukuthi ishintshwe ngesikhathi sokuphila kwesistimu.

Esikhundleni sokucabanga ngesimiso, kungcono ukwazi izimpawu zevalvu eqala ukwehluleka. Siqeqesha ithimba likaBudi ukufundisa amakhasimende “ukubheka, ukulalela, nokuzwa.” Uphawu oluvame kakhulu ukuthi isibambo siba siqinile kakhulu noma kube nzima ukusiphendula. Lokhu kungasho ukwakheka kwamaminerali noma uphawu olugugile ngaphakathi. Olunye uphawu noma yikuphi ukukhala noma ukuconsa okuvela eduze kwesiqu sesibambo, okubonisa ukuthi ama-O-rings ayahluleka. Uma uvala ivalvu futhi amanzi esangena, ibhola langaphakathi noma izihlalo cishe ziyaklwebheka noma zonakale. Lokhu kungenzeka uma usebenzisa ivalvu yebhola ukugeleza kwe-throttle esikhundleni sokulawula okulula kokuvula/ukuvala. Ngaphandle kokuthi ivalvu ibonise enye yalezi zimpawu, asikho isizathu sokuyishintsha. Ivalvu esezingeni eliphezulu yenzelwe ukuhlala isikhathi eside, ngakho-ke udinga kuphela ukuthatha isinyathelo lapho ikutshela ukuthi kunenkinga.

Izimpawu Zokuthi Ivalvu Yebhola Idinga Ukushintshwa

Ingabe i-valve yokuhlola i-PVC ingaba yingozi?

Unevalvu yokuhlola evimbela ukugeleza kwamanzi emuva, kodwa ifihliwe phansi komugqa wephampu. Ukwehluleka kungabonakala kuze kube yilapho iphampu yakho ilahlekelwa amanzi ahlanzekile noma angcolile ageleza emuva.

Yebo,I-valve yokuhlola ye-PVCkungaba yingozi nakanjani. Ukwehluleka okuvamile kufaka phakathi ukuguga kwesivalo sangaphakathi, ukuphuka kwehinji yevalvu yokujika, noma ingxenye ehambayo igcwala udoti, okubangela ukuthi yehluleke.

Nakuba sigxile kuma-ball valve, lo mbuzo omuhle ngoba ama-check valve nawo abaluleke kakhulu. Ayingxenye "yokusetha bese uyikhohlwa", kodwa anezingxenye ezihambayo ezingaguga. Ukwehluleka okuvamile kakhulu ku-ivalvu yokuhlola yesitayela sokujikai-flap ayivali kahle esihlalweni. Lokhu kungaba ngenxa yesivalo senjoloba esigugile noma imfucumfucu encane njengesihlabathi ebanjwa kuso. Kuma-valve okuhlola agcwele intwasahlobo, isipilingi sensimbi ngokwaso singagcina sigqwalile noma sikhathele, okubangela ukuba siphuke. Umzimba we-valve, njenge-valve yebhola, uqinile kakhulu ngoba wenziwe nge-PVC. Kodwa izingxenye zangaphakathi zemishini yizona zinto ezibuthakathaka. Yingakho ukuthenga i-valve yokuhlola esezingeni eliphezulu kubaluleke kakhulu. Eklanywe kahle enophawu oluqinile kanye nendlela eqinile yokubopha izonikeza iminyaka eminingi yesevisi ethembekile futhi ivikele uhlelo lwakho ekugelezeni okubuyayo.

Isiphetho

Ivalvu yebhola ye-PVC esezingeni eliphezulu ingahlala amashumi eminyaka, ngokuvamile impilo yonke yesistimu. Zishintshe ngokusekelwe esimweni, hhayi ohlelweni, futhi zizohlinzeka ngensizakalo eyingqayizivele nethembekile.
