Ungxamile ukuvala amanzi, kodwa isiphatho sevalvu sivakala ngathi sifakwe isamente endaweni yaso. Uyoyika ukuba ukongeza amandla amaninzi kuya kusiqhawula isiphatho.
Intsha kracaIvalvu yebhola yePVCKunzima ukuyijika kuba izivalo zayo zangaphakathi eziqinileyo zenza ukuba ilingane kakuhle, ingavuzi. Ivalvu endala idla ngokuba lukhuni ngenxa yokwakheka kweeminerali okanye ishiywe kwindawo enye ixesha elide.
Lo ngumbuzo endiwuphendulayo kuwo onke amaqabane amatsha, kuquka neqela likaBudi e-Indonesia. Kuqhelekile kangangokuba impendulo iyinxalenye yoqeqesho lwethu oluqhelekileyo. Xa umthengi evakalelwa kukuba ukuqina kokuqala, ingcinga yakhe yokuqala isenokuba kukuba imveliso ayinaso isiphene. Ngokuchaza ukuba oku kuqina luphawu lomgangatho ophezulu, oluqinileyo, siguqula isikhalazo esinokubakho sibe yindawo yokuzithemba. Olu lwazi luncinci lunceda abathengi bakaBudi ukuba bathembe iimveliso zePntek abazifakayo, nto leyo eqinisa ubudlelwane bethu obuphumeleleyo.
Kutheni kunzima kangaka ukujika iivalvu zebhola zePVC?
Usandul’ ukuvula ivalvu entsha ebhokisini kwaye isiphatho siyamelana nethuba lakho. Uqala ukuzibuza ukuba uthenge imveliso ekumgangatho ophantsi engayi kukwenzakalisa xa uyidinga kakhulu.
EntshaIivalvu zebhola zePVCKunzima ukuzijika ngenxa yokungqubana phakathi kwezihlalo zePTFE ezomileyo nezinyamezelayo kunye nebhola entsha yePVC. Oku kuqina kokuqala kuqinisekisa ukuba kuya kwenziwa isitywina esigqibeleleyo nesingenakuvuza.
Makhe ndingene nzulu kwinkqubo yokwenziwa, njengoko oku kuchaza yonke into. Siyila iivalvu zethu zePntek ngenjongo enye ephambili: ukunqanda ukuhamba kwamanzi ngokupheleleyo. Ukufezekisa oku, sisebenzisa kakhuluukunyamezelana okuqinileyoIzinto eziphambili yibhola yePVC egudileyo kunye neeringi ezimbini ezibizwa ngokuba yiIzihlalo ze-PTFE. Usenokuba uyazi i-PTFE ngegama layo lophawu, iTeflon. Xa ujika isiphatho, ibhola ijikeleza ezi zihlalo. Kwivalvu entsha, ezi ndawo zicocekile kwaye zomile ngokugqibeleleyo. Ukujika kokuqala kufuna amandla angakumbi kuba uyoyisa ukungqubana okungaguqukiyo phakathi kwezi ndawo zintsha. Kufana nokuvula ijagi entsha; ukujika kokuqala kuhlala kunzima kuba kukwaphula isitywina esigqibeleleyo. Ivalvu ejika ngokulula kakhulu kwasekuqaleni inokuba nokunyamezelana okukhululekileyo, okunokukhokelela ekuvuzeni kancinci phantsi koxinzelelo. Ke, ukuqina kokuqala bubungqina obuhle onabo bevalvu eyenziwe kakuhle nethembekileyo.
Ungazi njani ukuba ivalvu yePVC ayilunganga?
Ivalvu yakho ayisebenzi kakuhle. Awuqinisekanga ukuba ibambekile kwaye ifuna amandla athile, okanye ukuba iphukile ngaphakathi kwaye kufuneka itshintshwe ngokupheleleyo.
Ivalvu yePVC ayilunganga ukuba ivuza kwisiphatho okanye emzimbeni, ivumela amanzi ukuba adlule xa ivaliwe, okanye ukuba isiphatho sijika singayeki ukuhamba kwamanzi. Ukuqina kwayo ayilophawu lokusilela.
Kubathengi bekontraka kaBudi, ukwazi umahluko phakathi kwevalvu eqinileyo kunye nevalvu embi kubalulekile ekwenzeni isigqibo esifanelekileyo sokulungisa. Ivalvu embi ineempawu ezicacileyo zokungaphumeleli ezidlula nje ekubeni nzima ukuyijika. Kubalulekile ukujonga ezi mpawu zithile.
| Uphawu | Ithetha ukuthini | Kufuneka isenzo |
|---|---|---|
| Amathontsi avela kwiSikhondo seSiphatho | Iisitywino sangaphakathi se-O-ringayiphumelelanga. | Kufuneka itshintshwe. |
| Uqhekeko Olubonakalayo Emzimbeni | Umzimba wevalvu uyachaphazeleka, ngokuqhelekileyo ngenxa yokubethwa okanye ukubanda. | Kufuneka itshintshwe ngoko nangoko. |
| Amanzi Ayathontsiza Xa Evaliwe | Ibhola okanye izihlalo zangaphakathi zifunyenwe okanye zonakele. Itywina liphukile. | Kufuneka itshintshwe. |
| Isiphatho Sijikeleza Ngokukhululekileyo | Unxibelelwano phakathi kwesiphatho kunye nesiqu sangaphakathi luphukile. | Kufuneka itshintshwe. |
Ukuqina kwevalvu entsha kuyinto eqhelekileyo. Nangona kunjalo, ukuba ivalvu endala eyayisoloko ijika ngokulula iba lukhuni kakhulu, idla ngokubonisaukwakheka kwezimbiwa zangaphakathiNangona ingekho “mbi” ngengqiqo yokuba yaphukile, ibonisa ukuba ivalvu iphelelwe lixesha kwaye kufuneka icwangciselwe ukutshintshwa.
Yeyiphi i-lubricant efanelekileyo kwiivalvu zebhola?
Ingqondo yakho ikuxelela ukuba uthathe ibhotile yesithambisi sokutshiza ukuze wenze ivalvu eqinileyo. Kodwa uyathandabuza, uxhalabile ukuba le khemikhali ingenza iplastiki ibe buthathaka okanye ingcolise umngxuma wamanzi.
Eyona nto ikhuselekileyo nesebenzayo kwiivalvu zebhola zePVC yigrisi esekwe kwi-silicone eyi-100%. Ungaze usebenzise iimveliso zepetroli ezifana ne-WD-40, kuba ziya kwenza iPVC ibe buthathaka kwaye ibangele ukuba iqhekeke.
Le yeyona ngcebiso ibalulekileyo yokhuseleko endinokuyinika, kwaye ndiyaqinisekisa ukuba lonke iqumrhu laseBudi liyayiqonda. Ukusebenzisa i-lubricant engalunganga kubi kunokusebenzisa i-lubricant kwaphela. Iimveliso eziqhelekileyo zasekhaya ezifana ne-WD-40, i-petroleum jelly, kunye neeoyile ezisetyenziswa ngokubanzi zisekelwe kwi-petroleum. Ezi khemikhali azihambelani ne-PVC. Zisebenza njengesinyibilikisi, ziqhekeza kancinci ulwakhiwo lwekhemikhali yeplastiki. Oku kwenza i-PVC ibe buthathaka kwaye ibe buthathaka. Ivalvu ethanjiswe ngale ndlela inokuba lula namhlanje, kodwa inokuqhekeka kwaye iqhume phantsi koxinzelelo ngomso. Ekuphela kwento ekhuselekileyo kumzimba we-PVC, ii-EPDM O-rings, kunye nezihlalo ze-PTFE zeziIgrisi ye-silicone eyi-100%I-silicone ayinayo ikhemikhali, oko kuthetha ukuba ayizukuyichaphazela okanye yonakalise izinto zevalvu. Kwiinkqubo ezithwala amanzi okusela, kubalulekile ukuba i-silicone lubricant nayo iqinisekiswe "I-NSF-61"ukuqinisekisa ukuba ikhuselekile ekutyeni."
Ngaba iivalvu zebhola ziyabambeka?
Akuzange kufuneke usebenzise ivalvu ethile yokuvala kangangeminyaka. Ngoku kukho imeko engxamisekileyo, kodwa xa usiya kuyijika, isiphatho siyabanda ngokupheleleyo endaweni yaso, asivumi ukuhamba kwaphela.
Ewe, iivalvu zebhola ziyabambeka ngokupheleleyo, ingakumbi ukuba azisetyenziswanga ixesha elide. Izizathu eziphambili zizinto ezibangelwa ngamanzi aqinileyo aqinisa ibhola endaweni yayo okanye ukunamathela kwezitywini zangaphakathi.
Oku kwenzeka ngalo lonke ixesha, kwaye yingxaki ebangelwa kukungasebenzi. Xa ivalvu ihleli kwindawo enye kangangeminyaka, ingakumbi kwindawo enamanzi aqinileyo njenge-Indonesia, zininzi izinto ezinokwenzeka ngaphakathi. Eyona ngxaki ixhaphakileyo yileukwakheka kwezimbiwaAmanzi aqulathe iiminerali ezinyibilikisiweyo ezifana necalcium kunye nemagnesium. Ekuhambeni kwexesha, ezi minerali zinokungena phezu kwebhola kunye nezihlalo, zenze uqweqwe oluqinileyo olufana nekhonkrithi. Esi sikali sinokuyiqinisa ibhola kwindawo evulekileyo okanye evaliweyo. Esinye isizathu esiqhelekileyo kukunamathela okulula. Izihlalo zePTFE ezithambileyo zinokunamathela kancinci okanye zinamathele kwibhola yePVC ekuhambeni kwexesha ukuba zicinezelwe kunye ngaphandle kokuhamba. Ndisoloko ndixelela uBudi ukuba acebise "ulondolozo lokuthintela"kubathengi bakhe. Kwiivalvu ezibalulekileyo zokuvala, kufuneka bajike nje isiphatho kube kanye okanye kabini ngonyaka. Ukujika ngokukhawuleza kwindawo evaliweyo nokubuyela ekuvulekeni yikho konke okufunekayo ukuze kwaphulwe naluphi na udidi oluncinci kwaye kuthintelwe ukuba izitywini zinganamatheli.
Isiphelo
Intsha eqathaivalvu yePVCibonisa uphawu olusemgangathweni. Ukuba ivalvu endala iyabhajwa, kusenokwenzeka ukuba ibangelwa kukwakheka kwayo. Sebenzisa i-silicone lubricant kuphela, kodwa ukuyitshintsha kudla ngokuba sisisombululo esilumkileyo sexesha elide.
