Ungxamele ukuvala amanzi, kodwa isiphatho sevalvu sivakala ngathi sifakwe isamente endaweni yayo. Unoloyiko lokuba ukongeza amandla angakumbi kuya kusihlutha nje isiphatho.

Entsha kracaIvalve yebhola yePVCKunzima ukujika kuba amatywina ayo angaphakathi aqinile enza ulungelelwano olugqibeleleyo, nobungqina bokuvuza. Ivalve endala idla ngokuba yomelele ngenxa yokwakheka kweeminerali okanye ukushiywa kwindawo enye ixesha elide.

Lo ngumbuzo endiwuphendulayo neqabane ngalinye elitsha, kuquka neqela likaBudi e-Indonesia. Iqhelekile kangangokuba impendulo yinxalenye yoqeqesho lwethu olusemgangathweni. Xa umthengi evakalelwa kukuba ukuqina kokuqala, ingcinga yabo yokuqala inokuba kukuba imveliso inesiphene. Ngokuchaza ukuba olu lukhuni luphawu lomgangatho ophezulu, isitywina esiqinileyo, sijika isikhalazo esinokubakho kwindawo yokuzithemba. Olu lwazi luncinci lunceda abathengi beBudi ukuba bathembe iimveliso zePntek abazifakelayo, okomeleza ubambiswano lwethu lokuwina.

Kutheni iivalvu zebhola zePVC zinzima kangaka ukuzijika?

Ukhuphe ivalve entsha kwaye umqheba uyaxhathisa ithuba lakho. Uqala ukubuza ukuba uthenge imveliso ekumgangatho ophantsi eya kuthi ingaphumeleli xa uyifuna kakhulu.

EntshaIivalvu zebhola zePVCKunzima ukujika ngenxa yengxabano phakathi kwezihlalo ze-PTFE ezomileyo, ezinokunyamezela kunye nebhola entsha ye-PVC. Obu bunzima bokuqala buqinisekisa ukuba itywina eligqibeleleyo, elingenabungqina bokuvuza liya kwenziwa.

Makhe ndingene nzulu kwinkqubo yokuvelisa, njengoko oku kuchaza yonke into. Siyila iivalvu zethu zePntek ngenjongo enye yokuqala: ukumisa ukuhamba kwamanzi ngokupheleleyo. Ukufezekisa oku, sisebenzisa kakhuluukunyamezela okuqinileyo. Amacandelo aphambili yibhola yePVC egudileyo kunye namakhonkco amabini abizwaIzihlalo ze-PTFE. Unokuyazi i-PTFE ngegama layo lohlobo, iTeflon. Xa ujika isiphatho, ibhola ijikeleza ngokuchasene nezi zihlalo. Kwivalve entsha, le miphezulu icoceke ngokugqibeleleyo kwaye yomile. Ujiko lokuqala lufuna amandla angaphezulu kuba woyisa ukungqubana okumileyo phakathi kwala malungu matsha kraca. Kufana nokuvula ingqayi entsha; ijiji yokuqala isoloko inzima kakhulu kuba kukwaphula itywina eligqibeleleyo. Ivalve ejika ngokulula kakhulu ukusuka ekuqaleni inokuba nonyamezelo olukhululekileyo, olunokukhokelela ekuvuzeni okucothayo phantsi koxinzelelo. Ke, obo bunzima bokuqala bobona bungqina bugqwesileyo bevalve eyenziwe kakuhle, ethembekileyo.

Ungazi njani ukuba i-valve ye-PVC imbi?

Ivalve yakho ayisebenzi kakuhle. Awuqinisekanga ukuba ibambekile kwaye idinga amandla athile, okanye ukuba yophukile ngaphakathi kwaye ifuna ukutshintshwa ngokupheleleyo.

Ivalve yePVC imbi ukuba ivuza kumqheba okanye emzimbeni, ivumela amanzi ukuba adlule xa ivaliwe, okanye ukuba isiphatho siyajika singayeki ukuhamba. Ukuqina ngokwakho akulophawu lokusilela.

Kubathengi beekontraka zeBudi, ukwazi umahluko phakathi kwevalve eqinileyo kunye nevalve embi kubalulekile ukwenza isigqibo esifanelekileyo sokulungisa. Ivalve embi ineempawu ezicacileyo zokungaphumeleli ezihamba ngaphaya nje kokuba nzima ukujika. Kubalulekile ukujonga ezi mpawu zikhethekileyo.

Ukuqina kwivalve entsha kuqhelekile. Nangona kunjalo, ukuba ivalve endala ebikade ijika ngokulula iba lukhuni ngokugqithisileyo, ihlala ikhombe kuyoukwakhiwa kwamaminerali angaphakathi. Nangona ingekho "imbi" ngengqiqo yokwaphulwa, ibonisa ivalve ekupheleni kobomi bayo obuluncedo kwaye kufuneka icwangciselwe ukutshintshwa.

Sesiphi esona sixhobo sokuthambisa sevalvu yebhola?

Ithuku lakho likuxelela ukuba ubambe inkonkxa yesithambiso sokutshiza sevalve eqinileyo. Kodwa uyathandabuza, unexhala lokuba imichiza inokuyenza buthathaka iplastiki okanye ingcolise umgca wamanzi.

I-lubricant kuphela ekhuselekileyo nesebenzayo kwiivalvu zebhola ze-PVC yi-100% ye-silicone-based grease. Ungaze usebenzise iimveliso zepetroleum ezifana ne-WD-40, njengoko ziya kwenza i-PVC ibe brittle kwaye ibangele ukuba iqhekeke.

Eli lelona cebiso libalulekileyo lokhuseleko endinokulinika, kwaye ndiyaqinisekisa ukuba umbutho kaBudi uphela uyawuqonda. Ukusebenzisa i-lubricant engalunganga kubi kunokusebenzisa i-lubricant kwaphela. Iimveliso zekhaya eziqhelekileyo ezifana ne-WD-40, i-petroleum jelly, kunye ne-oyile yenjongo jikelele isekelwe kwi-petroleum. Ezi khemikhali azihambelani nePVC. Zisebenza njengesinyibilikisi, ngokucothayo ziqhekeza ubume bemichiza yeplastiki. Oku kwenza i-PVC ibe brittle kwaye ibuthathaka. Ivalve ethanjiswe ngolu hlobo inokujika ibe lula namhlanje, kodwa inokuqhekeka kwaye igqabhuke phantsi koxinzelelo ngomso. Izinto kuphela ezikhuselekileyo kumzimba wePVC, i-EPDM O-rings, kunye nezihlalo ze-PTFE.I-100% igrisi ye-silicone. I-Silicone i-inert yekhemikhali, oku kuthetha ukuba ayiyi kusabela okanye yonakalise izixhobo zevalve. Kwiinkqubo ezithwala amanzi okusela, kubalulekile ukuba i-lubricant ye-silicone nayo iqinisekiswe "NSF-61” ukuqinisekisa ukuba kukhuselekile ukutya.

Ingaba iivalve zebhola ziyaxinga?

Akufuneki ukuba usebenzise ivalve ethile yokuvala iminyaka. Ngoku kukho imeko engxamisekileyo, kodwa xa usiya kuyijika, isibambo sikhenkceke ngokupheleleyo endaweni, sisala ukuhamba konke konke.

Ewe, iivalve zebhola ziyaxinga, ngakumbi ukuba aziqhutywa ixesha elide. Izizathu eziphambili ziyi-mineral scale ukusuka kumanzi anzima e-cementing ibhola kwindawo okanye izitywina zangaphakathi ezinamathele.

Oku kwenzeka ngalo lonke ixesha, kwaye yingxaki ebangelwa kukungasebenzi. Xa ivalve ihlala kwindawo enye iminyaka, ngakumbi kwindawo enamanzi aqinileyo njengoninzi lwase-Indonesia, izinto ezininzi zinokwenzeka ngaphakathi. Owona mba uxhaphakileyo nguloukwakhiwa kweeminerali. Amanzi aneeminerali ezinyibilikisiweyo ezifana ne-calcium kunye ne-magnesium. Ngokuhamba kwexesha, ezi zimbiwa zinokufaka phezu kwebhola kunye nezihlalo, zenze uqweqwe oluqinileyo olufana nekhonkrithi. Esi sikali sinokuyiqinisa ngokoqobo ibhola kwindawo evulekileyo okanye evaliweyo. Esinye isizathu esiqhelekileyo kukuncamathela okulula. Izihlalo ezithambileyo ze-PTFE zinokubambelela ngokucothayo okanye zincamathele kwibhola yePVC ekuhambeni kwexesha ukuba zicinezelwe kunye ngaphandle kokushukuma. Ndihlala ndimxelela uBudi ukuba acebise "ukugcinwa kothintelo"Kubathengi bakhe." Kwiivalve ezibalulekileyo zokuvala, kufuneka baguqule isiphatho kanye okanye kabini ngonyaka.Ukujika ngokukhawuleza kwindawo evaliweyo kunye nokubuyisela ukuvula konke okufunekayo ukuqhawula nasiphi na isikali esincinci kunye nokuthintela amatywina ekubambeni.

Ukuqukumbela

Intsha eqinileyoIvalve yePVCibonisa umgangatho wetywina. Ukuba ivalve endala iyaxinga, kusenokwenzeka ukuba isuke kulwakhiwo. Sebenzisa kuphela i-silicone lubricant, kodwa ukutshintshwa kudla ngokuba sisisombululo esilumkileyo sexesha elide.
