Umgangatho oPhakamileyo webhola edadayo yokukhangela ivalve yaseTshayina umnikezeli wefektri Umenzi
Yintoni ivalve yokukhangela ibhola edadayo?
Ivalve yokutshekisha luhlobo lwesivalo ngenjongo yokuba uni-directional, ngokunjalo njengeevalvu ezingabuyiyo.
AIvalve yokukhangela ibhola edadayoyivalve elula nethembekileyo enebhola engqukuva njengeyona ndawo ishukumayo ukuvala umva.Ngenxa yokuhamba kwayo okulula kunye noyilo olungenalo ukugcinwa kwevalve ngokuqhelekileyo ichazwe kwaye isetyenziswe kwizikhululo zokunyusa amanzi amdaka angaphantsi kwamanzi.Isihlalo sevalve esigcweleyo senziwe ngokukodwa sivumela ibhola ukuba ihlale ivuza-iqinile ngaphandle kokungena kwi-wedge kwisihlalo sevalve.Xa kusenziwa ivacuum okanye ivalve yokuchasa amanzi, kusetyenziswa ibhola "edadayo" endaweni "ezikileyo".
Ivalve yokukhangela ibhola edadayoqulathe ibhola ehlala esitulweni, enomngxuma omnye wokuphumela.Isebenza ngebhola ehla inyuka ngaphakathi kwevalve.Isihlalo senziwe ngoomatshini ukuze silingane ibhola, kwaye igumbi limiliselwe ukukhokela ibhola kwisihlalo ukuze itywine kwaye imise ukujikeleza okubuyela umva.Xa uxinzelelo olusemva kwesihlalo ludlula olo lungaphezu kwebhola, ulwelo luvumelekile ukuba luhambe ngevalve.Kodwa xa uxinzelelo olungaphezulu kwebhola lugqithise uxinzelelo olungaphantsi kwesihlalo, ibhola ibuyela ekuphumleni esihlalweni, yenze itywina elithintela ukubuya ngasemva.
Iimpawu eziphambili zevalve yokujonga ibhola yeFloat
Iimpawu kunye nezibonelelo zeIbhola Hlola iValve
- *Ivalve yokukhangela ibhola yi-aIvalve elula nethembekileyo enebhola engqukuva njengeyona ndawo ishukumayo ukuthintela ukubuya umva,uyilo olungenalo ugcino, olulungele izikhululo zokuphakamisa amanzi amdaka angaphantsi kwamanzi.
- *Isitulo sevalve esigcweleyo siyilwe ngokukodwa sivumela ibhola ukuba ihlale ivuza-iqinile ngaphandle kokungena kwi-wedge kwivalve.
- *NortechIbhola Hlola iValveziyazicoca, njengoko ibhola ijikeleza ngexesha lokusebenza nto leyo esusa umngcipheko wokungcola okuxinga ebholeni.
- *I-bore epheleleyo kunye negudileyo iqinisekisa ukuhamba okupheleleyo kunye nokulahlekelwa kwengcinezelo ephantsi kwaye isusa umngcipheko weediphozithi ezantsi ezinokuthi zithintele ukuvalwa okuqinileyo.Ibhola eliqhelekileyo liyilwe nge-NBR ye-rubber ene-metal core, kwaye ukuqina kwerabha kulungiselelwe ukukhusela ibhola ekubeni ixinge esitulweni.Iibhola ze-polyurethane zifanelekile kwimidiya ye-abrasive kwaye xa iibhola ezahlukeneyo zobunzima zifunekayo ukukhusela ingxolo kunye nehamile yamanzi.

uMboniso weMveliso: Ivalve yokukhangela ibhola edadayo
Ukusetyenziswa kwevalve yokukhangela ibhola edadayo
Olu hloboIvalve yokukhangela ibhola edadayoisetyenziswa kakhulu kwizicelo zamanzi amdaka, kwizityalo zamandla kunye neshishini lenkqubo.Ivalve yokujonga ibhola ikulungele ukusetyenziswa kumajelo angcolisekileyo (ukuya kuthi ga kwi-120˚F) njengoko ivelufa emile okwebhola ithintela ukugcwala kokungcola.Ngokuqhelekileyo isikhululo sokuphakamisa amanzi amdaka siya kuba nevalve yokujonga ibhola ukuthintela ukubuya umva.Ikwasetyenziswa ngokubanzi kwizitishi zokumpompa ezingafane zizinyaswe, kuba zifuna ulondolozo olunyiniweyo kuphela.
