Kuya kufuneka uvale amanzi, kodwa isiphatho sevalvu asizukushukuma. Usebenzisa amandla angakumbi, uxhalabile ukuba uza kuwaphula ngokupheleleyo, nto leyo ekushiya unengxaki enkulu nangakumbi.
Iivalvu ezintsha zebhola zePVC kunzima ukuzijika ngenxa yesitywino esomileyo nesiqinileyo phakathi kwezihlalo zePTFE kunye nebhola entsha yePVC. Oku kuqina kokuqala kuqinisekisa isitywino esingavuziyo kwaye kudla ngokuncipha emva kokujika okumbalwa.
Mhlawumbi lo ngumbuzo oqhelekileyo abathengi bakaBudi abanawo malunga nevalvu entsha. Ndisoloko ndimxelela ukuba achaze ukuba okuukuqina ngokwenene luphawu lomgangathoOku kuthetha ukuba ivalvu yenziwe nge-ukunyamezelana okuqinileyo ukwenza uphawu olugqibeleleyo nolulungileyo. Iindawo zangaphakathi zintsha kwaye azikasetyenziswa okwangoku. Endaweni yokuba yingxaki, luphawu lokuba ivalvu iya kwenza umsebenzi wayo wokumisa amanzi ngokupheleleyo. Ukuqonda oku kunceda ukulawula ulindelo kwaye kwakha ukuzithemba kwimveliso ukususela ekuqaleni.
Ungayenza njani i-PVC ball valve ijike lula?
Ujongene nevalvu elukhuni. Ulingeka ukuba ubambe isikrufu esikhulu, kodwa uyazi ukuba oko kunokuqhekeza isiphatho okanye umzimba wePVC, kuguqule ingxaki encinci ibe kukulungiswa okukhulu.
Ukuze kube lula ukujika ivalvu yePVC, sebenzisa isixhobo esifana ne-channel-lock pliers okanye i-valve wrench eyenzelwe wena ukuze ufumane amandla angaphezulu. Bamba isiphatho ngokuqinileyo kufutshane nesiseko saso uze usifake uxinzelelo oluqinileyo nolulinganayo ukuze usijike.
Ukusebenzisa amandla agqithisileyo yeyona ndlela ikhawulezayo yokwaphulaivalvu yePVC. Isitshixo kukusebenzisa amandla angaphezulu, kungekhona amandla angaqhelekanga. Ndisoloko ndicebisa uBudi ukuba abelane ngezi ndlela zifanelekileyo nabathengi bakhe abathengisa izinto. Okokuqala, ukuba ivalvu intsha kwaye ayikafakwa, ngumkhwa olungileyo ukujika isiphatho sibuyele umva izihlandlo ezimbalwa. Oku kunceda ukuhlalisa ibhola ngokuchasene nezitywini ze-PTFE kwaye kunokunciphisa kancinci ukuqina kokuqala. Ukuba ivalvu sele ifakiwe, eyona ndlela ilungileyo kukusebenzisa isixhobo ukuze ufumane inzuzo yoomatshini.isikrufu sentamboifanelekile kuba ayizukonakalisa isiphatho, kodwa iipliers ezitshixa itshaneli zisebenza kakuhle. Kubaluleke kakhulu ukubamba isiphatho kufutshane nomzimba wevalvu kangangoko kunokwenzeka. Oku kunciphisa uxinzelelo kwisiphatho ngokwaso kwaye kusebenzisa amandla ngqo kwisiqu sangaphakathi, kunciphisa umngcipheko wokuqhekeka kweplastiki.
Kutheni ivalvu yam yebhola kunzima kangaka ukuyijika?
Ivalvu endala eyayisakuba yintle ngoku isusiwe. Uzibuza ukuba ingaba yaphukile ngaphakathi na, kwaye ingcinga yokuyinqumla yintloko ebuhlungu ongayidingiyo.
Ivalvu yebhola iba nzima ukuyijika ngokuhamba kwexesha ngenxa yokwakheka kweeminerali emanzini aqinileyo, ukungcola okuhlala kwindlela yokusebenza, okanye izitywini zomile kwaye zinamathele emva kweminyaka zikwindawo enye.
Xa ivalvu iba nzima ukuyijika kamva ebomini bayo, idla ngokuba ngenxa yeemeko zendalo, kungekhona isiphene sokwenziwa kwayo. Eli linqaku elibalulekileyo ekufuneka iqela likaBudi liqonde xa lijongana nezikhalazo zabathengi. Banokuyixilonga ingxaki ngokusekwe kubudala bevalvu kunye nokusetyenziswa kwayo. Kukho izizathu ezimbalwa eziqhelekileyo zokuba oku kwenzeke:
| Ingxaki | Unobangela | Isisombululo esiBalaseleyo |
|---|---|---|
| Ukuqina kweValve entsha | I-fektri entshaIzihlalo ze-PTFEziqinile xa zithelekiswa nebhola. | Sebenzisa isixhobo sokulawula amandla; ivalvu iya kuba lula xa isetyenziswa. |
| Ukwanda kwezimbiwa | I-calcium kunye nezinye iiminerali ezivela emanzini aqinileyo zenza isikali kwibhola. | Ivalvu kusenokwenzeka ukuba kufuneka inqunyulwe ize itshintshwe. |
| Inkunkuma okanye iNkunkuma | Isanti okanye amatye amancinci avela kumjelo wamanzi ayanamathela kwivalvu. | Ukutshintshwa yindlela ekuphela kwayo yokuqinisekisa ukutywinwa okufanelekileyo. |
| Ukusetyenziswa Okungaqhelekanga | Ivalvu ishiywa ivuliwe okanye ivaliwe kangangeminyaka, nto leyo ebangela ukuba izitywini zinamathele. | Ukujika rhoqo (kanye ngonyaka) kunokuthintela oku. |
Ukuqonda ezi zizathu kunceda ukuchazela umthengi ukuba ukulungiswa kweevalvu, kunye nokutshintshwa kwazo ekugqibeleni, yinxalenye eqhelekileyo yobomi benkqubo yemibhobho.
Ngaba ndingayithambisa ivalvu yebhola yePVC?
Ivalvu iqinile, kwaye imvakalelo yakho yokuqala kukufafaza i-WD-40 kuyo. Kodwa uyathandabuza, uzibuza ukuba ingaba le khemikhali iza konakalisa iplastiki okanye ingcolise amanzi akho okusela.
Akufuneki usebenzise i-lubricant esekelwe kwi-petroleum efana ne-WD-40 kwi-PVC valve. Ezi khemikhali ziya konakalisa iplastiki ye-PVC kunye nezitywini. Sebenzisa i-lubricant esekelwe kwi-silicone eyi-100% kuphela ukuba kuyimfuneko.
Esi sisilumkiso esibalulekileyo sokhuseleko endisinika bonke amaqabane ethu. Phantse zonke ii-lubricants eziqhelekileyo zasekhaya, ii-oyile, kunye nee-greases ziyasebenza.esekelwe kwi-petroleumIi-petroleum distillates zibangela ukusabela kweekhemikhali ngeplastiki yePVC eyenza ukuba ibe buthathaka kwaye ibe buthathaka. Ukuzisebenzisa kunokubangela ukuba umzimba wevalvu uqhekeke phantsi koxinzelelo kwiiyure okanye kwiintsuku kamva. Eyona nto ilungileyo nefanelekileyo kwiPVC, EPDM, kunye nePTFE yileIgrisi ye-silicone eyi-100%Ayisebenzi ngokweekhemikhali kwaye ayizukulimaza izinto zevalvu. Ukuba inkqubo yenzelwe amanzi okusela, i-silicone lubricant nayo kufunekaIsiqinisekiso se-NSF-61ukuba ithathwe njengekhuselekileyo ekutyeni. Nangona kunjalo, ukuyisebenzisa ngokuchanekileyo kufuna ukunciphisa uxinzelelo kumgca kwaye rhoqo kuqhawulwe ivalvu. Kwiimeko ezininzi, ukuba ivalvu endala iqinile kangangokuba ifuna ukuthambisa, luphawu lokuba isondela esiphelweni sobomi bayo, kwaye ukutshintshwa kwayo lolona khetho lukhuselekileyo noluthembekileyo.
Yeyiphi indlela yokujika ivalvu yebhola yePVC?
Ukwivalvu, ulungele ukuyijika. Kodwa yeyiphi indlela evulekileyo, kwaye yeyiphi indlela evaliweyo? Unethuba elingama-50/50, kodwa ukuqikelela okungafanelekanga kunokubangela ukugaleleka kwamanzi okungalindelekanga.
Ukuze uvule ivalvu yebhola yePVC, jika isiphatho ukuze silingane nombhobho. Ukuze usivale, jika isiphatho sibe yikota (90 degrees) ukuze sime nkqo kumbhobho.
Lo ngumthetho osisiseko kakhulu wokusebenzaivalvu yebhola, kwaye uyilo lwayo oluqaqambileyo lubonelela ngesikhombisi esibonakalayo ngoko nangoko. Indawo yesiphatho ifana nendawo yomngxuma ebholeni ngaphakathi. Xa isiphatho sihamba kwicala elifanayo nombhobho, amanzi anokugeleza. Xa isiphatho siwela umbhobho ukuze senze imo "ye-T", ukuhamba kwamanzi kuyavalwa. Ndinika iqela likaBudi ibinzana elilula lokufundisa abathengi babo: "Emgceni, amanzi ageleza kakuhle." Lo mthetho ulula ususa yonke into yokuqikelela kwaye ngumgangatho oqhelekileyo weevalvu zebhola ezijika ikota, nokuba zenziwe ngePVC, ithusi, okanye intsimbi. Indlela oyijika ngayo—ngokwewotshi okanye ngokuchasene newotshi—ayinamsebenzi kangako njengendawo yokugqibela. Ukujika kweedigri ezingama-90 yeyona nto yenza iivalvu zebhola zikhawuleze kwaye kube lula ukuzisebenzisa xa kucinywa ngokukhawuleza.
Isiphelo
Iqinileivalvu yePVCludla ngokuba luphawu lwesitywino esitsha nesiqinileyo. Sebenzisa i-leverage engaguqukiyo, ungonakalisi ii-lubricants. Ukuze usebenze, khumbula umthetho olula: i-parallel ivuliwe, i-perpendicular ivaliwe.
