Ujahe ukuvala amanzi, kodwa isibambo sevalvu sizwa sengathi sifakwe usimende endaweni. Unovalo lokuthi ukwengeza amandla engeziwe kuzovele kunqamule isibambo.

Okusha shaI-valve yebhola ye-PVCKunzima ukuphenduka ngoba izigxivizo zayo zangaphakathi eziqinile zakha ukulingana okuphelele, okungavuzi. Ivalvu endala ivamise ukuqina ngenxa yokwakheka kwamaminerali noma ukushiywa endaweni eyodwa isikhathi eside kakhulu.

Lona umbuzo engiwuphendulayo kubo bonke ozakwethu abasha, okuhlanganisa nethimba lika-Budi e-Indonesia. Kuvame kakhulu ukuthi impendulo iyingxenye yokuqeqeshwa kwethu okujwayelekile. Uma ikhasimende lizwa lokho kuqina kwasekuqaleni, umcabango walo wokuqala kungaba ukuthi umkhiqizo unesici. Ngokuchaza ukuthi lokhu kuqina kuwuphawu lwekhwalithi ephezulu, uphawu oluqinile, siphendulela isikhalazo sibe iphuzu lokuzethemba. Lolu lwazi oluncane lusiza amakhasimende akwa-Budi ukuthi athembe imikhiqizo ye-Pntek ayifakayo, okuqinisa ubambiswano lwethu lokuwina-wini.

Kungani ama-valve ebhola e-PVC enzima kangaka ukuwavula?

Usanda kukhipha i-valve entsha ebhokisini futhi isibambo siyamelana nesikhathi sakho. Uqala ukungabaza uma uthenge umkhiqizo wekhwalithi ephansi ongeke uphumelele lapho uwudinga kakhulu.

OkushaAma-valve ebhola e-PVCkunzima ukuzijika ngenxa yokungqubuzana phakathi kwezihlalo ze-PTFE ezomile, ezibekezelela kakhulu kanye nebhola elisha le-PVC. Lokhu kuqina kokuqala kuqinisekisa ukuthi uphawu oluphelele, olungavuzi luzokwenziwa.

Ake ngingene ngijule ohlelweni lokukhiqiza, njengoba lokhu kuchaza yonke into. Siklama amavalvu ethu e-Pntek ngenjongo eyodwa eyinhloko: ukumisa ukugeleza kwamanzi ngokuphelele. Ukufeza lokhu, sisebenzisa kakhuluukubekezelelana okuqinile. Izingxenye ezibalulekile yibhola le-PVC elibushelelezi namasongo amabili abizwaIzihlalo ze-PTFE. Ungase wazi i-PTFE ngegama layo lomkhiqizo, i-Teflon. Uma uphendula isibambo, ibhola lizungeza lezi zihlalo. Ku-valve entsha, lezi zindawo zihlanzeke ngokuphelele futhi zome. Ukujika kokuqala kudinga amandla engeziwe ngoba unqoba ukungqubuzana okumile phakathi kwalezi zingxenye ezintsha sha. Kufana nokuvula imbiza entsha; i-twist yokuqala ihlale ilukhuni kakhulu ngoba iphula uphawu oluphelele. I-valve ephenduka kalula kusukela ekuqaleni ingase ibe nokubekezelela okuxekethile, okungaholela ekuvuzeni okunensayo ngaphansi kwengcindezi. Ngakho-ke, lokho kuqina kokuqala kuwubufakazi obungcono kakhulu bokuthi i-valve eyenziwe kahle, ethembekile.

Ungazi kanjani ukuthi i-valve ye-PVC ayilungile?

I-valve yakho ayisebenzi kahle. Awunaso isiqiniseko sokuthi ingabe isamile futhi idinga amandla athile, noma uma iphukile ngaphakathi futhi idinga ukushintshwa ngokuphelele.

Ivalvu ye-PVC yimbi uma ivuza esibanjeni noma emzimbeni, ivumela amanzi ukuthi adlule lapho ivaliwe, noma uma isibambo siphenduka ngaphandle kokumisa ukugeleza. Ukuqina ngokwakho akulona uphawu lokwehluleka.

Kumakhasimende osonkontileka beBudi, ukwazi umehluko phakathi kwevalve eqinile nevalve embi kubalulekile ekwenzeni isinqumo esifanele sokulungisa. I-valve embi inezimpawu ezicacile zokuhluleka ezidlula nje ukuba nzima ukuyijika. Kubalulekile ukubheka lezi zimpawu ezithile.

Ukuqina ku-valve entsha kuvamile. Kodwa-ke, uma i-valve endala ejwayele ukujika kalula iba lukhuni ngokwedlulele, ivamise ukukhombaukwakheka kwamaminerali angaphakathi. Nakuba “ingeyimbi” ngomqondo wokuphuka, ikhombisa ukuthi ivalvu isekupheleni kokusebenza kwayo futhi kufanele ihlelelwe ukushintshwa.

Iyiphi i-lubricant engcono kakhulu yama-valve ebhola?

Umzwelo wakho wemvelo ukutshela ukuthi uthathe ithini le-spray lubricant ye-valve eqinile. Kodwa uyangabaza, ukhathazekile ngokuthi ikhemikhali ingase yenze buthaka ipulasitiki noma ingcolise umzila wamanzi.

Okuwukuphela kwendlela yokugcoba ephephile nesebenzayo yamavalvu ebhola e-PVC igrisi esekelwe ku-silicone engu-100%. Ungalokothi usebenzise imikhiqizo ye-petroleum efana ne-WD-40, njengoba izokwenza i-PVC ibe brittle futhi ibangele ukuthi iqhekeke.

Lesi iseluleko esibaluleke kakhulu sokuphepha engingasinikeza, futhi ngiyaqinisekisa ukuthi yonke inhlangano kaBudi iyasiqonda. Ukusebenzisa okokugcoba okungalungile kubi kakhulu kunokungasebenzisi nhlobo okokugcoba. Imikhiqizo yasendlini evamile njenge-WD-40, i-petroleum jelly, namafutha enhloso evamile isekelwe ku-petroleum. Lawa makhemikhali awahambisani ne-PVC. Basebenza njenge-solvent, kancane kancane bephula ukwakheka kwamakhemikhali epulasitiki. Lokhu kwenza i-PVC ibe brittle futhi ibe buthakathaka. Ivalvu egcotshwe ngale ndlela ingase ibe lula namuhla, kodwa ingase iqhekeke futhi iqhume ngaphansi kwengcindezi kusasa. Okuwukuphela kwento ephephile emzimbeni we-PVC, ama-EPDM O-rings, kanye nezihlalo ze-PTFEI-silicone grease engu-100%.. I-Silicone ayisebenzi ngamakhemikhali, okusho ukuthi ngeke isabele noma ilimaze izinto ze-valve. Kuzinhlelo ezithwala amanzi okuphuza, kubalulekile ukuthi i-silicone lubricant nayo iqinisekiswe "I-NSF-61” ukuqinisekisa ukuthi iphephile ekudleni.

Ingabe ama-valve ebhola ayabhajwa?

Awudingi ukusebenzisa i-valve ethile yokuvala iminyaka. Manje kunesimo esiphuthumayo, kodwa uma uyosijika, isibambo siqandiswe ngokuphelele endaweni, senqaba nhlobo ukunyakaza.

Yebo, ama-valve ebhola ayabhajwa, ikakhulukazi uma engasebenzi isikhathi eside. Izimbangela eziyinhloko isikali samaminerali esivela emanzini aqinile afaka ibhola endaweni noma izimpawu zangaphakathi ezinamathele.

Lokhu kwenzeka ngaso sonke isikhathi, futhi kuyinkinga ebangelwa ukungasebenzi. Uma i-valve ihlezi endaweni eyodwa iminyaka, ikakhulukazi endaweni enamanzi aqinile njengengxenye enkulu ye-Indonesia, izinto ezimbalwa zingenzeka ngaphakathi. Udaba oluvame kakhuluukwakheka kwamaminerali. Amanzi aqukethe amaminerali ancibilikisiwe njenge-calcium ne-magnesium. Ngokuhamba kwesikhathi, lawa amaminerali angafaka phezu kwebhola nezihlalo, enze uqweqwe oluqinile olufana nokhonkolo. Lesi sikali singafaka usimende ngokoqobo ibhola endaweni evulekile noma evaliwe. Esinye isizathu esivamile ukunamathela okulula. Izihlalo ezithambile ze-PTFE zinganamathela kancane kancane noma zinamathele ebholeni le-PVC ngokuhamba kwesikhathi uma zicindezelwe ndawonye ngaphandle kokunyakaza. Ngihlale ngitshela uBudi ukuthi ancome “ukugcinwa kokuvimbela” Kumakhasimende akhe.Kumavalvu okuvala abalulekile, kufanele bamane baphendule isibambo kanye noma kabili ngonyaka.Ukujika ngokushesha endaweni evaliwe bese ubuyela emuva ukuze uvule yikho kuphela okudingekayo ukugqabula noma yisiphi isikali esincane futhi uvimbele izingxivizo ekunamatheleni.

Isiphetho

Okusha okuqinileI-valve ye-PVCibonisa uphawu lwekhwalithi. Uma i-valve endala ibambeka, kungenzeka ukuthi isuke ekubunjweni kwayo. Sebenzisa kuphela okokugcoba kwe-silicone, kodwa ukushintshwa ngokuvamile kuyisixazululo esihlakaniphe kakhulu sesikhathi eside.
