A SIvalufa yeDisc etywiniweyo rhoqoyamkelwa ngokubanzi ngomsebenzi wayo ogqwesileyo wokutywina, ukuqina, kunye nokuziqhelanisa nonikezelo lwamanzi kunye neenkqubo zemibhobho yoshishino. Esi sikhokelo esinzulu sichaza ukuba yintoni i-valve ye-disc etywinwe ngokuthambileyo, isebenza njani, iingenelo zayo kwiivalvu zemveli ezihlala ngentsimbi, izicelo eziphambili, ukhetho lwezinto eziphathekayo, imigangatho, kunye neengcebiso zokugcina. Ingaba uyinjineli, umphathi weprojekthi, okanye ingcali yokuthengwa kwempahla, eli nqaku liza kukunceda ukhethe ngokuzithemba ivalve efanelekileyo yokuthembeka kokusebenza kwexesha elide.
A Ivalufa yeDiskhi etywiniweyo ethambileyoluhlobo lwevalve yokuvala esebenzisa i-resilient seal material-efana ne-EPDM, i-NBR, okanye i-PTFE-kwi-disc ukufezekisa ukutywinwa okuqinileyo, okungenamaqamza. Ngokungafaniyo noyilo lwesinyithi ukuya kwisinyithi, ukutywinwa okuthambileyo kuqinisekisa ukuvuza okuncinci naphantsi kweemeko zoxinzelelo oluphantsi.
Ezi zivalo zisetyenziswa ngokuqhelekileyo kumanzi acocekileyo, amanzi amdaka, i-HVAC, kunye neenkqubo zolwelo lwamashishini apho ukutywinwa okuthembekileyo kunye ne-torque ephantsi yokusebenza kubalulekile.
Umgaqo wokusebenza usekelwe kwintshukumo ethe nkqo okanye ene-angle yediski ecinezela indawo ethambileyo yokutywina ngokuchasene nesihlalo sevalve ukumisa ukuhamba. Xa ivuliwe, i-disc iphakamisa, ivumela ulwelo ukuba ludlule ngokuxhathisa okuncinci.
Iivalvu zediski ezitywiniweyo zibonelela ngeenzuzo ezininzi zokusebenza, zizenza zibe lolona khetho lukhethwayo kwiinkqubo ezininzi zemibhobho:
| Uphawu | Ivalufa yeDiskhi etywiniweyo ethambileyo | Metal-Seated Disc Valve |
|---|---|---|
| Ukutywinwa kokuSebenza | Igqwesile (iqiniswe ngamaqamza) | Phakathi |
| ITorque esebenzayo | Phantsi | Phezulu |
| Nxiba ukuxhathisa | Phakathi | Phezulu |
| Imidiya eqhelekileyo | Amanzi, amanzi amdaka, ulwelo oluphakathi | Ubushushu obuphezulu okanye ulwelo olurhabaxa |
Iivalve zediski ezitywiniweyo zisetyenziswa ngokubanzi kumashishini amaninzi ngenxa yokuguquguquka kwazo:
Abavelisi bayathandaGongchuangukubonelela ngeevalvu zediski ezitywiniweyo ezilungiselelwe ukusebenza kwexesha elide kwiiprojekthi zeziseko ezingundoqo ezifunwayo.
| Icandelo | Izinto eziqhelekileyo | Umsebenzi |
|---|---|---|
| Umzimba weValve | Intsimbi yentsimbi, iNtsimbi yentsimbi | Inkxaso yolwakhiwo |
| Icwecwe | I-Ductile Iron ene-Rubber Coating | Flow control and sealing |
| Uluhlu lokutywina | EPDM, NBR | Ukuthintela ukuvuza |
Xa ukhetha i-valve yediski etywiniweyo, qwalasela ezi zinto zilandelayo:
Ukufumana iinkcukacha ezicacileyo zemveliso, bhekisa kubavelisi abaqeqeshiweyo abafana nababoneleli ngediskhi etywiniweyo.
Iivalvu zedisc ezitywiniweyo ezikumgangatho ophezulu kufuneka zihambelane nemigangatho eyaziwayo:
Ukugcinwa okufanelekileyo kunokwandisa kakhulu ubomi bevalve yediski etywiniweyo:
Ewe. Xa ziveliswa ngezinto zerabha eziqinisekisiweyo ezifana ne-EPDM, iivalve ze-disc ezitywiniweyo zikhuselekile kwiinkqubo zamanzi okusela.
Zifanelekile kwiinkqubo zoxinzelelo oluphakathi. Kuxinzelelo oluphezulu kakhulu, uyilo oluhlala ngesinyithi lunokufaneleka ngakumbi.
Ngokufakela kunye nokugcinwa okufanelekileyo, ubomi benkonzo bunokudlula iminyaka eyi-10-15 kwizicelo zamanzi eziqhelekileyo.
Ukukhetha okulungileyoIvalufa yeDiskhi etywiniweyo ethambileyoibalulekile ekuqinisekiseni ukuthembeka kwenkqubo, ukusebenza kakuhle, kunye nokonga iindleko zexesha elide. Ngokuqonda isakhiwo sayo, izixhobo, izicelo, kunye nemigangatho, unokwenza izigqibo ezinolwazi malunga nonikezelo lwamanzi kunye neeprojekthi zemizi-mveliso.
Ukuba ujonge izisombululo ezithembekileyo zevalve yedisk etywiniweyo kumvelisi onamava afanaGongchuang, uzive ukhululekile ukubaQhagamshelana nathinamhlanje ngenkxaso yobugcisa kunye neengcebiso ezenziwe ngokwezifiso.
