Uyila inkqubo kwaye kufuneka uthembele kumalungu akho. Ivalve engaphumeleliyo inokuthetha ixesha lokuphumla kunye nokulungiswa okuxabisa imali eninzi, oko kukwenza ubuze ukuba ngaba loo nxalenye yePVC efikelelekayo ibifanelekile.
Ivalve yebhola yePVC ekumgangatho ophezulu, eyenziwe ngezinto ezinyulu yaze yasetyenziswa ngokuchanekileyo, ingahlala iminyaka eyi-10 ukuya kwengama-20, kwaye kaninzi kubo bonke ubomi benkqubo yemibhobho efakelwe kuyo. Ubomi obude buxhomekeke kumgangatho, usetyenziso, kunye nokusingqongileyo.
Lo mbuzo usentliziyweni yento esiyenzayo. Ndikhumbula incoko noBudi, iqabane eliphambili lokuhambisa iincwadi zethu eIndonesia. Omnye wabathengi bakhe, umasibambisane omkhulu wezolimo, wayethandabuza ukusebenzisa eyethuIivalvu zePVC. Zazisetyenziselwa ukutshintsha iivalvu zazo zentsimbi ezidlekayo rhoqo emva kweminyaka embalwa kwaye babengakholelwa ukuba isivalo “seplastiki” siya kuhlala ixesha elide. UBudi wabacenga ukuba bazame ezimbalwa kweyona migcana yabo yokunkcenkceshela isichumiso esinzima. Oko kwenzeka kwiminyaka esixhenxe eyadlulayo. Ndikhe ndangena naye kwinyanga ephelileyo, kwaye wandixelela ukuba ezo zivalo ziyafana zisasebenza ngokugqibeleleyo. Abazange batshintshe enye. Nguwo umahluko umgangatho owenzayo.
Yintoni ubude bobomi bevalve yebhola yePVC?
Kufuneka ucwangcisele ulondolozo kunye neendleko zokutshintsha. Ukusebenzisa inxalenye enobomi obungaziwayo kwenza uhlahlo lwabiwo-mali lwakho lube luqikelelo olupheleleyo kwaye kunokukhokelela kukusilela okungalindelekanga endleleni.
Ubomi benkonzo obulindelekileyo bomgangatho wevalve yebhola ye-PVC ngokuqhelekileyo i-10 ukuya kwi-20 iminyaka. Noko ke, kwiimeko ezifanelekileyo—kumanzi angaphakathi, abandayo, ukungasetyenziswa rhoqo—kunokuhlala ixesha elide. Izinto eziguquguqukayo eziphambili kumgangatho wezinto eziphathekayo, ukuvezwa kwe-UV, kunye noxinzelelo lokusebenza.
Ubomi bevalve ayilonani elinye; sisiphumo sezinto ezininzi ezibalulekileyo. Eyona nto ibalulekileyo yimathiriyeli ekrwada. E-Pntek, sisebenzisa kuphela i-100% ye-PVC ye-resin enyulu. Oku kuqinisekisa amandla aphezulu kunye nokumelana neekhemikhali. Iivalvu ezingabizi kakhulu zihlala zisetyenziswa"regrind" (i-PVC esetyenzisiweyo), enokuthi ibe brittle kwaye ingalindelekanga. Enye into enkulu kukukhanya kwe-UV kukukhanya kwelanga. I-PVC eqhelekileyo inokuba buthathaka ngokuhamba kwexesha ukuba ishiywe elangeni, yiyo loo nto sibonelela ngeemodeli ezithile ezinganyangekiyo kwi-UV kwizicelo zangaphandle ezifana nokunkcenkceshela. Ekugqibeleni, cinga ngamatywina. Sisebenzisa izihlalo ezomeleleyo ze-PTFE ezibonelela ngetywina eligudileyo, elisezantsi elimelana namawakawaka. Iivalvu ezingabizi kakhulu ezinamatywina erabha asemgangathweni ziya kuguga ngokukhawuleza. Utyalo-mali kumgangatho ongaphambili yeyona ndlela iqinisekileyo yokuqinisekisa ubomi obude.

Zithembeke kangakanani iivalvu zebhola zePVC?
Udinga icandelo onokuthi ulifake kwaye ulibale ngalo. Ivalve engathembekanga ithetha ukuxhalaba rhoqo malunga nokuvuza okunokwenzeka, ukuvalwa kwenkqubo, kunye nokulungiswa okumdaka, okuxabisa imali eninzi. Kuyingozi ongenakukwazi ukuyihlawula.
Ngenjongo yabo yokulawula ukuhamba kwamanzi abandayo,iivalvu zebhola zePVC ezikumgangatho ophezuluzithembeke kakhulu. Ukuthembeka kwabo kuvela kuyilo olulula olunamacandelo ambalwa ahambayo kunye nezinto eziphathekayo ezikhuseleke ngokupheleleyo kwi-rust and corrosion.
Ukuthembeka kwevalvu kumalunga namandla ayo okumelana nokusilela okuqhelekileyo. Kulapho iPVC ikhanya ngokwenene. Ndihlala ndixelela uBudi ukuba acacise oku kubathengi bakhe abasebenza kufuphi nonxweme. Iivalvu zesinyithi, kwanezobhedu, ekugqibeleni ziya konakala kumoya onetyuwa nofumileyo. I-PVC ayifuni nje. Ayikhuselekanga kumhlwa kwaye uninzi lwekhemikhali yokubola efumaneka kwiinkqubo zamanzi. Omnye umthombo wokuthembeka kuyilo. Iivalvu ezininzi ezinexabiso eliphantsi zisebenzisa i-O-ring enye kwisiqu ukuthintela ukuvuza kumqheba. Eli linqanaba elaziwayo lokungaphumeleli. Siye sayila eyethu ngee-O-rings ezimbini. Lutshintsho oluncinci, kodwa lubonelela ngokutywinwa okungafunekiyo okonyusa kakhulu ukuthembeka kwexesha elide ngokuchasene nokuthontsiza. Indlela elula yokuguqula ikota kunye nomzimba onzima, ongagqwaliyo wenza ivalve yePVC esemgangathweni ibe yenye yezona ndawo zithembekileyo kuyo nayiphi na inkqubo yamanzi.
Kuvela phi ukuthembeka?
| Uphawu | Impembelelo kuNtembeko |
|---|---|
| I-Corrosion-proof Body | Amajoni omzimba kumhlwa, oqinisekisa ukuba ayizukuba buthathaka okanye ibambe ekuhambeni kwexesha. |
| Indlela elula | Ibhola kunye nomqheba zilula, kunye neendlela ezimbalwa kakhulu zokudiliza. |
| PTFE Izihlalo | Yenza itywina elomeleleyo, elihlala ixesha elide elingazukuthotywa lula. |
| I-Stem ephindwe kabini i-O-Rings | Ibonelela nge-backup engafunekiyo yokuthintela ukuvuza komqheba, indawo yokusilela eqhelekileyo. |
Kufuneka kutshintshwe kangaphi iivalvu zebhola?
Udinga isicwangciso solondolozo lwenkqubo yakho. Kodwa ngokuthatha indawo yamalungu angophukanga yinkcitho yemali, ngelixa ukulinda ixesha elide kunokukhokelela kukusilela okuyintlekele.
Iivalvu zebhola azinalo ishedyuli esisigxina yokutshintsha. Kufuneka zitshintshwe ngokwemeko, hayi kwisibali-xesha. Kwivalve ekumgangatho ophezulu kwinkqubo ecocekileyo, oku kunokuthetha ukuba akusoze kufuneke kutshintshwe ngexesha lokuphila kwenkqubo.
Endaweni yokucinga ngeshedyuli, kungcono ukwazi iimpawu zevalve eqala ukusilela. Siqeqesha iqela likaBudi ukuba lifundise abathengi ukuba "bajonge, bamamele, kwaye bazive." Olona phawu luxhaphakileyo sisiphatho siqina kakhulu okanye sibe nzima ukusijika. Oku kunokuthetha ukwakhiwa kweeminerali okanye ukunxitywa kwetywina ngaphakathi. Olunye uphawu nakuphi na ukulila okanye ukuvuza ukusuka kwisiqu somqheba, nto leyo ebonisa ukuba i-O-rings iyasilela. Ukuba uvala ivalve kwaye amanzi asathontsiza, ibhola yangaphakathi okanye izihlalo zinokukrweleka okanye zonakele. Oku kunokwenzeka ukuba usebenzisa ivalve yebhola ukuze ugibise ivalve endaweni yolawulo olulula lokuvula/ukuvala. Ngaphandle kokuba ivalve ibonisa enye yezi mpawu, akukho sizathu sokuyibuyisela endaweni yayo. Ivalve esemgangathweni yenzelwe ukuba ihlale, ngoko kufuneka usebenze kuphela xa ikuxelela ukuba kukho ingxaki.
Iimpawu zeValve yeBhola ifuna ukutshintshwa
| Uphawu | Oko Kusenokwenzeka Ukuba Lithetha | Isenzo |
|---|---|---|
| IsiHamba esiQinise kakhulu | Ukulinganisa kwangaphakathi kwamaminerali okanye ukutywinwa okungaphumeleli. | Phanda kwaye kunokwenzeka ukubuyisela. |
| Ukuvuza kwiHandle | Isiqu se-O-rings zigugile. | Tshintsha ivalve. |
| Ayivali Ukuhamba | Ibhola yangaphakathi okanye izihlalo zonakele. | Tshintsha ivalve. |
| Ukuqhekeka okubonakalayo kuMzimba | Umonakalo womzimba okanye ukuthotywa kwe-UV. | Faka enye indawo ngokukhawuleza. |
Ngaba ivalve yokujonga iPVC ingahamba kakubi?
Unayo ivalve yokukhangela ethintela ukuphuma kwasemva, kodwa ifihliwe ezantsi kumgca wempompo. Ukungaphumeleli kunokungaqatshelwa de impompo yakho ilahlekelwe yiprayimari okanye amanzi angcolileyo abuyela ngasemva.
Ewe, aIvalve yokujonga i-PVCngokuqinisekileyo inokuhamba kakubi. Ukusilela okuqhelekileyo kubandakanya ukuguga kwesitywina sangaphakathi, ihenjisi ekuqhawukeni kwevalve kajingi, okanye indawo eshukumayo izele bubutyobo, ibangele ukuba ingaphumeleli.
Ngelixa sijolise kwiivalvu zebhola, lo ngumbuzo omkhulu kuba iivalve zokukhangela zibaluleke kakhulu. Bayinxalenye "yokuyibeka kwaye uyilibale", kodwa banamalungu ashukumayo anokuphelelwa amandla. Eyona ntsilelo ixhaphakileyo kwi aivalve yokujonga isimbo sokujingiyiflap ayitywinwanga ngokugqibeleleyo kwisitulo. Oku kunokubangelwa kukutywinwa kwerabha egugileyo okanye inkunkuma encinci njengesanti ebanjwa kuyo. Kwii-valve ze-spring-loaded check valves, i-spring spring ngokwayo inokugqiba ukugqwala okanye ukukhathala, okubangela ukuba iphule. Umzimba wevalve, njengevalve yebhola, womelele kakhulu kuba wenziwa ngePVC. Kodwa iindawo zangaphakathi zoomatshini ngamanqaku abuthathaka.
