Kufuneka uvale amanzi, kodwa isiphatho sevalve asiyi kushukuma. Usebenzisa amandla angakumbi, unexhala lokuba uya kuwaphula ngokupheleleyo, akushiye nengxaki enkulu ngakumbi.
Iivalvu zebhola zePVC ezintsha kunzima ukuzijika ngenxa yetywina eliqinileyo, elomileyo phakathi kwezihlalo zePTFE kunye nebhola entsha yePVC. Oku kuqina kokuqala kuqinisekisa ukutywinwa okungavuzi kwaye kudla ngokuba lula emva kokujika okumbalwa.
Lo ngowona mbuzo uqhelekileyo abanawo abathengi bakaBudi malunga nevalve entsha kraca. Ndihlala ndimxelela ukuba ayicacise loo ntoukuqina ngokwenene luphawu lomgangatho. Kuthetha ukuba ivalve yenziwe kakhuluukunyamezelana okuqinileyo ukwenza isitywina esigqibeleleyo, esilungileyo. Amalungu angaphakathi matsha kwaye akakanxitywa okwangoku. Endaweni yokuba yingxaki, luphawu lokuba ivalve iya kwenza umsebenzi wayo wokumisa amanzi ngokupheleleyo. Ukuqonda oku kunceda ukulawula okulindelweyo kwaye kwakha ukuzithemba kwimveliso ukusuka ekuqaleni.
Indlela yokwenza ivalve yebhola yePVC ibe lula?
Ujongene nevalve enenkani. Ulingeka ukuba ubambe i-wrench enkulu, kodwa uyazi ukuba inokukrazula isibambo se-PVC okanye umzimba, ukuguqula umcimbi omncinci ube yinto enkulu yokulungisa.
Ukwenza ivalve ye-PVC ijike lula, sebenzisa isixhobo esifana nepliers yokutshixa itshaneli okanye isitshixo sevalve esizinikeleyo ukuze ufumane amandla awongezelelekileyo. Bamba isiphatho ngokuqinileyo kufutshane nesiseko saso kwaye usebenzise ngokuzinzileyo, nkqu noxinzelelo lokusijika.
Ukusebenzisa amandla agqithisileyo yeyona ndlela ikhawulezayo yokwaphula aIvalve yePVC. Undoqo kukusebenzisa amandla, hayi amandla akhohlakeleyo. Ndihlala ndicebisa uBudi ukuba abelane ngezi ndlela zifanelekileyo kunye nabathengi bakhe bekontraka. Okokuqala, ukuba ivalve yintsha kwaye ayikafakwa, luqhelo oluhle ukujikisa isiphatho umva naphambili amaxesha ambalwa. Oku kunceda ukuhlalisa ibhola ngokuchasene namatywina e-PTFE kwaye kunokunciphisa kancinci ukuqina kokuqala. Ukuba ivalve sele ifakiwe, eyona ndlela ilungileyo kukusebenzisa isixhobo soncedo lomatshini. Aumtya wokutshixailungile kuba ayizukonakalisa isiphatho, kodwa iipliers zokutshixa isitishi zisebenza kakuhle. Kubaluleke kakhulu ukubamba isiphatho ngokusondeleyo kumzimba wevalve kangangoko kunokwenzeka. Oku kunciphisa uxinzelelo kwisibambo ngokwalo kwaye kusetyenziswa amandla ngokuthe ngqo kwisiqu sangaphakathi, ukunciphisa umngcipheko wokukrazula iplastiki.
Kutheni ivalve yam yebhola inzima kangaka ukuyijika?
Ivalve endala eyayifudula ijijeka ngoku iyabanjwa. Uyazibuza ukuba iphukile ngaphakathi, kwaye ingcinga yokuyinqunqa yintlungu ebuhlungu ongayidingi.
Ivalve yebhola iba nzima ukuyijika ngokuhamba kwexesha ngenxa yokwakheka kweeminerali ezivela kumanzi aqinileyo, ubutyobo olungena kwindlela yokwenza izinto, okanye amatywina ayoma kwaye abambeke emva kweminyaka bekwindawo enye.
Xa ivalve iba nzima ukuyijika kamva ebomini bayo, idla ngokuba ngenxa yezinto ezisingqongileyo, hayi isiphene sokwenza izinto. Le yeyona nto ibalulekileyo ukuze iqela likaBudi liqonde xa lifaka izikhalazo zabathengi. Bangakwazi ukuxilonga umba ngokusekelwe kwiminyaka yobudala kunye nokusetyenziswa kwevalve. Kukho izizathu ezimbalwa eziqhelekileyo oku kwenzeka:
| Ingxaki | Unobangela | Eyona Isisombululo |
|---|---|---|
| Ukuqina kweValve entsha | Umzi-mveliso-mtshaIzihlalo ze-PTFEziqinile ngokuchasene nebhola. | Sebenzisa isixhobo sokuphucula; ivalve iya kukhululeka xa isetyenziswa. |
| Ukwakhiwa kweMineral | I-calcium kunye nezinye iiminerali ezivela kwisikali samanzi anzima kwibhola. | Ivalve ifuna ukunqunyulwa ize itshintshwe. |
| Inkunkuma okanye intlenga | Isanti okanye amatye amancinci asuka kumgca wamanzi axinga kwivalve. | Ukutshintshwa kuphela kwendlela yokuqinisekisa itywina elifanelekileyo. |
| Ukusetyenziswa rhoqo | Ivalve ishiywe ivuliwe okanye ivaliwe iminyaka, ibangela ukuba amatywina abambelele. | Ukuguquka ngamaxesha (kanye ngonyaka) kunokuthintela oku. |
Ukuqonda ezi zizathu kunceda ukucacisela umthengi ukuba ukugcinwa kwevalvu, kwaye ekugqibeleni ukutshintshwa, yinxalenye eqhelekileyo yobomi benkqubo yemibhobho.
Ngaba ndingayithambisa ivalve yebhola yePVC?
Ivalve iqinile, kwaye ithuku lakho lokuqala kukutshiza i-WD-40 kuyo. Kodwa uyathandabuza, uzibuza ukuba ikhemikhali iya kuyonakalisa iplastiki okanye ingcolise amanzi okusela.
Ungaze usebenzise isithambiso esekwe kwi-petroleum njenge-WD-40 kwivalve ye-PVC. Ezi khemikhali ziya konakalisa iplastiki yePVC kunye netywina. Sebenzisa kuphela i-100% i-silicone-based lubricant ukuba kuyimfuneko.
Esi sisilumkiso esibalulekileyo sokhuseleko endisinika onke amaqabane ethu. Phantse zonke izithambiso zokutshiza zekhaya, ioyile, kunye negrisi zinjaloi-petroleum-based. I-Petroleum distillates ibangela ukusabela kweekhemikhali ngePVC yeplastiki eyenza ibe brittle kwaye ibe buthathaka. Ukuzisebenzisa kunokukhokelela ekubeni umzimba wevalvu uqhekeke phantsi kweeyure zoxinzelelo okanye iintsuku kamva. Ekuphela kwento yokuthambisa ekhuselekileyo nehambelanayo yePVC, EPDM, kunye nePTFE yiI-100% igrisi ye-silicone. I-inert yekhemikhali kwaye ayiyi kulimaza izakhi zevalvu. Ukuba inkqubo yeyamanzi okusela, i-lubricant ye-silicone kufuneka ibe nayoNSF-61 eqinisekisiweyoukuba kuthathwe njengokukhuselekileyo ekutyeni. Nangona kunjalo, ukuyisebenzisa ngokuchanekileyo kufuna ukuxinzelela umgca kwaye kaninzi ukuchithwa kwevalve. Kwiimeko ezininzi, ukuba ivalve endala iqinile kangangokuba ifuna ukuthanjiswa, luphawu lokuba sele isondele esiphelweni sobomi bayo, kwaye ukutshintshwa kwayo yeyona ndlela ikhuselekileyo nethembekileyo.
Yeyiphi indlela yokujika ivalve yebhola yePVC?
Ukwivalve, ulungele ukuyijika. Kodwa yeyiphi indlela evulekileyo, kwaye yeyiphi evaliweyo? Unethuba elingama-50/50, kodwa ukuthelekelela okungalunganga kunokubangela ukuphuma kwamanzi okungalindelekanga.
Ukuvula ivalve yebhola yePVC, jika isiphatho ukuze sihambelane nombhobho. Ukuyivala, vula isibambo ikota-turn (90 degrees) ngoko i-perpendicular kumbhobho.
Lo ngowona mgaqo usisiseko ekusebenzeni aivalve yebhola, kunye noyilo lwayo oluqaqambileyo lubonelela ngokukhawuleza okubonakalayo. Isikhundla somqheba silinganisa indawo yomngxuma kwibhola ngaphakathi. Xa isiphatho sihamba kwicala elinye nombhobho, amanzi anokuhamba. Xa isibambo siwela umbhobho ukwenza "T" imilo, ukuhamba kuvaliwe. Ndinika iqela likaBudi ibinzana elilula lokufundisa abathengi babo: "Emgceni, amanzi ahamba kakuhle." Lo mgaqo olula ususa yonke ingqikelelo kwaye ngumgangatho wendalo yonke kwiivalvu zebhola zekota, nokuba zenziwe ngePVC, ubhedu, okanye intsimbi. Indlela oyijika ngayo—njengewotshi okanye ikhawunta-njengexesha—ayinamsebenzi njengendawo yokugqibela. Ukujika kwe-90-degree yinto eyenza i-valve yebhola ngokukhawuleza kwaye kulula ukuyisebenzisela ukucima okungxamisekileyo.
Ukuqukumbela
IqinileIvalve yePVCluhlala luphawu lwetywina elitsha, eliqinileyo. Sebenzisa amandla azinzileyo, ungonakalisi izithambiso. Ukusebenza, khumbula umgaqo olula: i-parallel ivuliwe, i-perpendicular ivaliwe.
