Ubona i-valve yebhola ye-PVC, futhi intengo yayo ephansi ikwenza ungabaze. Ingabe ucezu lwepulasitiki lungaba yingxenye ethembekile ohlelweni lwami lwamanzi? Ingozi ibonakala iphezulu.

Yebo, amavalvu ebhola e-PVC asezingeni eliphezulu awagcini nje ngokuba mahle; amahle kakhulu futhi athembeke kakhulu ekusetshenzisweni kwawo okuhlosiwe. Ivalvu eyenziwe kahle eyenziwe nge-PVC engeyona ingozi enezihlalo ze-PTFE eziqinile izonikeza iminyaka yesevisi engenawo amanzi abandayo.

Ngihlala ngibhekana nalo mbono. Abantu babona “ipulasitiki” bese becabanga ukuthi “ishibhile futhi ibuthakathaka.” Ngenyanga edlule nje, bengikhuluma noBudi, umphathi wokuthenga engisebenza naye eduze e-Indonesia. Omunye wamakhasimende akhe amasha, i-farm cooperative, wayenqikaza ukusebenzisa i-Amavalvu e-PVCngesistimu yabo entsha yokunisela. Bebelokhu besebenzisa intengo ebiza kakhuluamavalvu ensimbi. Ngakhuthaza uBudi ukuba abanike amasampula. Ngemva kwamasonto amabili, ikhasimende laphinde lashaya ucingo, limangazwe. Amavalvu ethu ayevezwe kumanyolo kanye nomswakama oqhubekayo ngaphandle kophawu olulodwa lokugqwala okwakuhlasele amavalvu abo ensimbi amadala. Konke kumayelana nokusebenzisa izinto ezifanele zomsebenzi, futhi emisebenzini eminingi, i-PVC iyisinqumo esingcono kakhulu.

I-valve yebhola ye-PVC izohlala isikhathi esingakanani?

Uklama uhlelo futhi udinga ukwazi ukuthi izingxenye zakho zizohlala isikhathi esingakanani. Ukushintsha njalo ama-valve angasebenzi kuwukuchitha isikhathi, imali, futhi kuyinkinga enkulu.

Ivalvu yebhola ye-PVC esezingeni eliphezulu ingahlala iminyaka eyi-10 kuya kwengama-20 kalula, futhi ivame ukuba isikhathi eside kakhulu ngaphansi kwezimo ezifanele. Isikhathi sayo sokuphila sincike kakhulu ekhwalithini yokukhiqiza, ukuchayeka ku-UV, amakhemikhali amanzi, nokuthi isetshenziswa kaningi kangakanani.

Isikhathi sokuphila kwevalvu ye-PVC akuyona inombolo eyodwa nje; kungumphumela wezinto eziningana. Okubaluleke kakhulu ikhwalithi yezinto zokusetshenziswa. Kwa-Pntek, sigcizelela ukusebenzisaI-resin ye-PVC engu-100% emsulwaAma-valve ashibhile asebenzisa i-“regrind,” noma ipulasitiki ephinde yasetshenziswa, engaba buthakathaka futhi ingabikezeleki. Isici sesibili esikhulu ukusetshenziswa. Ingabe ingaphakathi noma ngaphandle? I-PVC ejwayelekile ingaba buthakathaka ngokuhamba kwesikhathi uma ishiswa yilanga ngqo, ngakho-ke sinikezaIzinketho ezingamelani ne-UVkulezo zinhlelo zokusebenza. Ingabe ivalvu iphendulwa kanye ngosuku noma kanye ngonyaka? Imvamisa ephezulu izogqoka izihlalo nezivalo ngokushesha. Kodwa ekusetshenzisweni kwamanzi abandayo okuvamile ngaphakathi kwesilinganiso sayo sokucindezela, ivalvu yebhola ye-PVC eyenziwe kahle iyisici sangempela sesikhathi eside. Ungayifaka bese uyikhohlwa iminyaka.

Izici Ezithinta Isikhathi Sokuphila Sevalvu Ye-PVC

Ama-valve ebhola e-PVC athembeke kangakanani?

Udinga ingxenye ongathembela kuyo ngokuphelele. Ukwehluleka kwevalvu eyodwa kungamisa yonke imisebenzi yakho, kubangele ukubambezeleka futhi kubize imali eningi ukuyilungisa.

Ngenhloso yawo ehlosiwe—ukulawula ukuvala nokuvula amanzi abandayo—ama-valve ebhola e-PVC asezingeni eliphezulu athembeke kakhulu. Ukuthembeka kwawo kuvela ekwakhiweni okulula okunezingxenye ezimbalwa ezihambayo nezinto ezingavikeleki ngokuphelele ekugqwaleni nasekugqwaleni, okuyizindawo eziyinhloko zokuhluleka kwama-valve ensimbi.

Ukuthembeka kwevalvu kungaphezu nje kwamandla ayo; kumayelana nokumelana kwayo nokwehluleka okuvamile. Yilapho i-PVC iphumelela khona. Cabanga ngevalvu yensimbi engaphansi komhlaba emanzi noma egqitshwe ngaphandle. Ngokuhamba kwesikhathi, izobola. Isibambo singagqwala, umzimba ungase wonakale. Ivalvu ye-PVC ayikutholi lokhu. I-Budi yake yathengisa amavalvu ethu ebhizinisini lezolimo zasemanzini elisogwini elalishintsha amavalvu ethusi njalo ezinyangeni ezingu-18 ngenxa yokugqwala kwamanzi anosawoti. Eminyakeni emihlanu kamuva, amavalvu ethu okuqala e-PVC asasebenza kahle. Esinye isihluthulelo sokuthembeka ukwakheka kwezivalo. Amavalvu ashibhile asebenzisa i-O-ring eyodwa yerabha esiqwini. Lena indawo evamile yokuvuza. Saklama amavalvu ethu ngeizindandatho ze-O eziphindwe kabili, enikeza isivalo esiphindaphindayo esiqinisekisa ukuthi isibambo ngeke siqale ukuconsa. Lo mklamo olula noqinile yiwona owenza zithembeke kangaka.

Lapho Ukuthembeka Kuvela Khona

Yiliphi i-brass noma i-PVC foot valve engcono?

Usetha iphampu futhi udinga ivalvu yonyawo. Khetha izinto ezingalungile, futhi ungase ubhekane nokugqwala, umonakalo, noma ngisho nokungcolisa wona kanye amanzi ozama ukuwapompa.

Akukho okungcono kakhulu emhlabeni wonke; ukukhetha kuncike esicelweni.I-valve yonyawo lwe-PVCkungcono emanzini agqwalayo kanye namaphrojekthi abiza kakhulu. Ivalvu yezinyawo zethusi ingcono ngenxa yamandla ayo angokomzimba ngokumelene nokushayisana kanye nokucindezela okuphezulu noma izinga lokushisa.

Ake sichaze lokhu. I-valve yonyawo uhlobo lwe-valve yokuhlola ehlezi phansi komugqa wokudonsa wephampu, igcina iphampu ikulungele. Umsebenzi oyinhloko ukuvimba amanzi ukuthi angaphinde aphume. Lapha, ukukhetha izinto kubalulekile. Inzuzo yokuqala yokuthiI-PVCukumelana kwayo nokugqwala. Uma upompa amanzi omthombo anokuqukethwe okuphezulu kwamaminerali, noma amanzi avela echibini lezolimo, i-PVC iyona ephumelelayo. Ithusi lingahlushwa ukubola, lapho amaminerali emanzini ekhipha i-zinc ku-alloy, okwenza ibe nezimbobo futhi ibe buthakathaka. I-PVC nayo ishibhile kakhulu. Inzuzo eyinhloko yeithusiukuqina kwayo. Iqinile kakhulu futhi ingamelana nokulahlelwa phansi emgodini womthombo noma ukushaywa emadwaleni ngaphandle kokuqhekeka. Emithonjeni ejulile kakhulu noma ekusetshenzisweni kwezimboni okunzima lapho amandla angokomzimba ebaluleke kakhulu, ithusi liyindlela ephephile.

I-PVC vs. I-Brass Foot Valve: Yikuphi Okufanele Ukhethe?

Ingabe ama-valve ebhola e-PVC ayahluleka?

Ufuna ukufaka ingxenye bese uyikhohlwa. Kodwa ukunganaki indlela ingxenye engaphuka ngayo kuyindlela yokudala inhlekelele, okuholela ekuvuza, ekulimaleni, nasekulungisweni okuphuthumayo.

Yebo, njenganoma iyiphi ingxenye yomshini, ama-valve ebhola le-PVC angahluleka. Ukwehluleka cishe njalo kubangelwa ukusetshenziswa kabi, njengokuwasebenzisa namanzi ashisayo noma amakhemikhali angahambisani, umonakalo ongokwenyama njengokuqandisa, noma ukuguguleka okulula ku-valve esezingeni eliphansi.

UkuqondaKanjaniUkwehluleka kuyisihluthulelo sokuvimbela lokhu. Ukwehluleka okubi kakhulu ukuqhekeka komzimba. Lokhu kuvame ukwenzeka ngesinye sezizathu ezimbili: ukuqinisa kakhulu intambo, okubeka ingcindezi enkulu ku-valve, noma ukuvumela amanzi ukuba aqine ngaphakathi kwayo. Amanzi ayakhula uma eqina, futhi azohlukanisa i-valve ye-PVC ivuleke kakhulu. Okunye ukwehluleka okuvamile ukuvuza. Kungavuza esibambweni uma isiquAma-O-ringsukuguga—isibonakaliso sevalvu eshibhile. Noma, ingahluleka ukuvala ngokuphelele. Lokhu kwenzeka lapho ibhola noma izihlalo ziklwejwa yitshe elisepayipini noma ziguga ngokusebenzisa ivalvu yebhola ngendlela engafanele ukuze kugeleze kahle. Ngihlala ngitshela uBudi ukuthi akhumbuze amakhasimende akhe: ayifake kahle, ayisebenzisele ukuvala amanzi abandayo kuphela, bese ethenga ivalvu esezingeni eliphezulu kwasekuqaleni. Uma wenza lezo zinto ezintathu, amathuba okuhluleka aba mancane kakhulu.

Ukwehluleka Okuvamile Nendlela Yokukuvimbela

Isiphetho

Ikhwalithi ephezuluAmavalvu ebhola le-PVCzinhle kakhulu, zithembekile, futhi zihlala isikhathi eside ngenxa yenhloso yazo eklanyelwe zona. Ukuqonda ukuthi zisetshenziswa kanjani ngendlela efanele nokuthi yini ebangela ukwehluleka kuyisihluthulelo sohlelo olungenakukhathazeka.
