Udinga ukuvala amanzi, kodwa isibambo sevalvu ngeke sinyakaze. Usebenzisa amandla amaningi, ukhathazekile ukuthi uzowaphula ngokuphelele, okukushiya unenkinga enkulu nakakhulu.

Amavalvu amasha ebhola le-PVC kunzima ukuwajika ngenxa yesivalo esiqinile, esomile phakathi kwezihlalo ze-PTFE nebhola elisha le-PVC. Lokhu kuqina kokuqala kuqinisekisa isivalo esingavuzi futhi kuvame ukudamba ngemva kokujika okumbalwa.

Lona mhlawumbe umbuzo ovame kakhulu amakhasimende kaBudi anawo nge-valve entsha sha. Ngihlala ngimtshela ukuthi achaze ukuthi lokhuukuqina empeleni kuwuphawu lwekhwalithiKusho ukuthi ivalvu yenziwe nge-ukubekezelelana okuqinile ukudala uphawu oluphelele noluhle. Izingxenye zangaphakathi zintsha futhi azikagqokwa okwamanje. Esikhundleni sokuba yinkinga, kuyinkomba yokuthi ivalvu izokwenza umsebenzi wayo wokuvimba amanzi ngokuphelele. Ukuqonda lokhu kusiza ekuphatheni okulindelwe futhi kwakha ukuzethemba kumkhiqizo kusukela ekuthinteni kokuqala.

Ungayenza kanjani i-PVC ball valve ibe lula?

Ubhekene nevalvu eqinile. Ulingeka ukubamba isikrufu esikhulu, kodwa uyazi ukuthi lokho kungaphula isibambo noma umzimba we-PVC, kuguqule inkinga encane ibe ukulungiswa okukhulu.

Ukuze wenze ukujika kwevalvu ye-PVC kube lula, sebenzisa ithuluzi elifana ne-channel-lock pliers noma i-valve wrench ekhethekile ukuze uthole amandla engeziwe. Bamba isibambo ngokuqinile eduze kwesisekelo saso bese usicindezela ngokuqinile, ngokulinganayo ukuze usiphendule.

Ukusebenzisa amandla ngokweqile kuyindlela esheshayo yokuphulaI-valve ye-PVC. Isihluthulelo yi-leverage, hhayi amandla amakhulu. Ngihlala ngicebisa uBudi ukuthi abelane ngalezi zindlela ezifanele namakhasimende akhe onkontileka. Okokuqala, uma ivalvu intsha futhi ingakafakwa, kuwumkhuba omuhle ukuphendula isibambo emuva naphambili izikhathi ezimbalwa. Lokhu kusiza ukusetha ibhola ngokumelene nezimbozo ze-PTFE futhi kunganciphisa kancane ukuqina kokuqala. Uma ivalvu isivele ifakiwe, indlela engcono kakhulu ukusebenzisa ithuluzi ukuze kube nenzuzo yemishini.isikrufu sebhandeKuhle kakhulu ngoba ngeke kuphazamise isibambo, kodwa izinti zokukhiya iziteshi zisebenza kahle. Kubaluleke kakhulu ukubamba isibambo eduze komzimba wevalvu ngangokunokwenzeka. Lokhu kunciphisa ukucindezeleka esibambweni ngokwaso futhi kusebenzisa amandla ngqo esiqwini sangaphakathi, kunciphisa ingozi yokuqhekeka kwepulasitiki.

Kungani ivalvu yami yebhola kunzima kangaka ukuyijika?

Ivalvu endala eyayivame ukuba yinhle manje isibanjiwe. Uzibuza ukuthi iphukile yini ngaphakathi, futhi umcabango wokuyinqamula uyikhanda elibuhlungu ongalidingi.

I-valve yebhola iba nzima ukuyiphendula ngokuhamba kwesikhathi ngenxa yokwakheka kwamaminerali emanzini aqinile, ukungcola okuhlala emshinini, noma izivalo zomile futhi zinamathele ngemva kweminyaka eminingi zisendaweni eyodwa.

Uma ivalvu iba nzima ukuyijika kamuva empilweni yayo, ngokuvamile kungenxa yezici zemvelo, hhayi iphutha lokukhiqiza. Leli iphuzu elibalulekile okufanele ithimba likaBudi liqonde lapho liphendula izikhalazo zamakhasimende. Bangakwazi ukuthola inkinga ngokusekelwe eminyakeni yevalvu kanye nokusetshenziswa kwayo. Kunezizathu ezimbalwa ezivamile ezenza lokhu kwenzeke:

Ukuqonda lezi zimbangela kusiza ukuchazela ikhasimende ukuthi ukulungiswa kwama-valve, kanye nokufakwa esikhundleni sawo ekugcineni, kuyingxenye evamile yomjikelezo wokuphila kwesistimu yamapayipi.

Ngingakwazi yini ukugcoba i-valve yebhola le-PVC?

Ivalvu iqinile, futhi umuzwa wakho wokuqala uwukufafaza i-WD-40 kuyo. Kodwa uyanqikaza, uzibuza ukuthi ngabe ikhemikhali izolimaza ipulasitiki noma ingcolise amanzi akho okuphuza.

Akufanele neze usebenzise i-lubricant esekelwe kuphethiloli njenge-WD-40 ku-valve ye-PVC. La makhemikhali azolimaza ipulasitiki ye-PVC kanye nezivalo. Sebenzisa i-lubricant esekelwe ku-silicone engu-100% kuphela uma kudingeka ngempela.

Lesi yisixwayiso esibalulekile sokuphepha engisinikeza bonke ozakwethu. Cishe zonke izinto zokugcoba ezivamile zasekhaya, amafutha, kanye namafutha ziyasebenza.okusekelwe kuphethiloliAma-petroleum distillates abangela ukusabela kwamakhemikhali ngepulasitiki ye-PVC okwenza kube buthaka futhi kube buthakathaka. Ukuwasebenzisa kungaholela ekutheni umzimba we-valve uqhekeke ngaphansi kwengcindezi emahoreni noma ezinsukwini kamuva. Okuwukuphela kokuthambisa okuphephile nokuhambisanayo kwe-PVC, EPDM, kanye ne-PTFE yilokhuAmafutha e-silicone angu-100%Ayisebenzi ngamakhemikhali futhi ngeke ilimaze izingxenye zevalvu. Uma uhlelo lungolwamanzi okuphuza, i-silicone lubricant nayo kumele ibeIsitifiketi se-NSF-61kufanele kubhekwe njengokuphephile ekudleni. Kodwa-ke, ukuyisebenzisa kahle kudinga ukunciphisa ukucindezela komugqa futhi kuvame ukuhlakaza ivalvu. Ezimweni eziningi, uma ivalvu endala iqine kangangokuthi idinga ukugcotshwa, kuyisibonakaliso sokuthi isondela ekupheleni kokuphila kwayo, futhi ukushintshwa kuyindlela ephephile nethembekile.

Iyiphi indlela yokuguqula ivalvu yebhola le-PVC?

Usevalvini, usukulungele ukuyijika. Kodwa iyiphi indlela evulekile, futhi iyiphi indlela evaliwe? Unethuba elingu-50/50, kodwa ukuqagela okungalungile kungabangela ukukhuphuka kwamanzi okungalindelekile.

Ukuze uvule ivalvu yebhola ye-PVC, phendula isibambo ukuze sihambisane nepayipi. Ukuze usivale, phendula isibambo ngekota (ama-degree angu-90) ukuze siqonde ngqo epayipini.

Lona umthetho oyisisekelo kakhulu wokusebenzaivalvu yebhola, futhi umklamo wayo omuhle kakhulu unikeza isibonakaliso esibonakalayo esisheshayo. Indawo yesibambo ilingisa indawo yembobo ebholeni ngaphakathi. Lapho isibambo sigijima ngendlela efanayo nepayipi, amanzi angageleza. Lapho isibambo siwela ipayipi ukuze senze isimo "se-T", ukugeleza kuyavinjelwa. Nginika ithimba likaBudi umusho olula wokufundisa amakhasimende abo: “Emgqeni, amanzi ageleza kahle.” Lo mthetho olula ususa konke ukuqagela futhi uyindinganiso evamile yamavalvu ebhola aphenduka ngekota, kungakhathaliseki ukuthi enziwe nge-PVC, ithusi, noma insimbi. Indlela oyijika ngayo—ngokwewashi noma ngokwewashi—ayinandaba kakhulu nendawo yokugcina. Ukujika kwama-degree angu-90 yikho okwenza amavalvu ebhola asheshe futhi kube lula ukuwasebenzisa ekuvaleni okuphuthumayo.

Isiphetho

UkuqinaI-valve ye-PVCngokuvamile kuwuphawu lokuvala okusha, okuqinile. Sebenzisa i-leverage eqinile, hhayi ukulimaza amafutha okugcoba. Ukuze usebenze, khumbula umthetho olula: ukuhambisana kuvulekile, u-perpendicular uvaliwe.
