Inqaku lokukwazisa malunga neevalvu zebhola zePVC
Umsebenzi wevalve yebhola yePVC
Ivalve yebhola, i-valve apho indawo yokuvula kunye nokuvala (ibhola) iqhutywe yi-valve stem kwaye ijikeleze i-axis ye-valve stem.Isetyenziselwa ikakhulu ukunqumla okanye ukudibanisa okuphakathi kwipayipi.Ingasetyenziselwa ukulungiswa kwamanzi kunye nokulawula.Phakathi kwazo, i-valve yebhola ye-V ene-hard-sealed i-V ine-shear eqinile phakathi kwe-core ye-V kunye nesihlalo sesinyithi se-alloy eqinile.Amandla okucheba afaneleke ngakumbi kumajelo eendaba aqulethe iintsinga kunye namasuntswana aqinileyo.
Ivalve yebhola eneendlela ezininzi kumbhobho ayinakulawula kuphela ukudityaniswa, ukwahluka, nokuqukuqela komzila ophakathi, kodwa ikwavale naliphi na itshaneli ukuqhagamshela amanye amajelo amabini.Olu hlobo lwevalve kufuneka lufakwe ngokubanzi ngokuthe tye kumbhobho.
Ukuhlelwa kwevalve yebhola: ivalve yebhola yepneumatic, ivalve yebhola yombane, ivalve yebhola yezandla.
Ulwazi olusisiseko
Ngokubanzi, ukusetyenziswa kweivalve yebhola yepvcakufunekanga idlule kwi-45 ℃, kwaye i-medium ayifanelekanga kwizinyibilikisi eziphilayo kunye nee-oxidants ezinamandla.Ngokwale meko, olu hlobo lwevalve yebhola lukhawulelwe ukusebenzisa amanzi angaphantsi kwe-45 ° C kwaye uxinzelelo lungaphantsi kwe-1.0mpa.
Xa kuthelekiswa nezinye iivalvu, ineenzuzo ezilandelayo.
1. Ukuxhathisa ulwelo oluphantsi
Ivalve yebhola yeyona inobuxhakaxhaka bolwelo phakathi kwazo zonke iivalvu, nkqu nevalve yebhola ecuthiweyo, ukuxhathisa kwayo ulwelo kuncinci kakhulu.Ivalve yebhola yePVC yimveliso entsha yevalvu yebhola ephuhliswe ngokweemfuno zolwelo lwemibhobho eyonakalisayo.Izibonelelo zemveliso: ubunzima obulula, ukuxhathisa okuqinileyo kwe-corrosion, i-compact kunye nenkangeleko enhle, ubunzima obulula kunye nokufakwa lula komzimba, ukuxhathisa okuqinileyo kwe-corrosion, uluhlu olubanzi lwesicelo, izinto ezicocekileyo kunye ne-non-toxic, ukumelana nokunxiba, ukuchithwa lula, ukulungiswa okulula.
Ukongeza kwizinto zeplastiki zePVC, iivalve zebhola zeplastiki zikwabandakanya iPPR, iPVDF, iPPH, iCPVC, njl.
2. Ivalve yebhola yePVC inokumelana nokugqwesa okugqwesileyo.
Umsesane wokutywina wamkela F4.Ukumelana nokugqwesa okugqwesileyo kunye nokwandisa ubomi benkonzo.Ukujikeleza okuguquguqukayo kwaye kulula ukuyisebenzisa.
3. Njengevalve yebhola edityanisiweyo, ivalve yebhola yePVC inamanqaku ambalwa okuvuza, amandla aphezulu, kwaye uhlobo loqhagamshelo lwebhola ivelufa kulula ukudibanisa kunye nokuqhawula.
Ufakelo kunye nokusetyenziswa kwevalve yebhola: Xa iiflange kwiziphelo zozibini zidityaniswe nombhobho, iibholithi kufuneka ziqiniswe ngokulinganayo ukuthintela i-flange ukuba ingakhubazeki kwaye ibangele ukuvuza.Jika isiphatho njengewotshi ukuze uvale, kwaye ngokuphambanayo uvule.Ingasetyenziselwa kuphela ukusika kunye nokuhamba-hamba, kwaye ukulungiswa kokuhamba akufanelekile.Ulwelo olunamasuntswana aqinileyo lunokukrwela ngokulula umphezulu webhola.
4.Umsebenzi owomeleleyo:
Uhlobo olukrelekrele, uhlobo olulinganayo, uhlobo lokutshintsha yonke into, ubungakanani obuncinci: umthamo ulingana kuphela malunga ne-35% yeemveliso ezifanayo.
5.Ukukhanya kunye nabantu abancinci:
Ubunzima bumalunga ne-30% yeemveliso ezifanayo, kwaye ukusebenza kunokwethenjelwa: iibheringi kunye namacandelo ombane athatha iimveliso zebrand eyaziwayo kumazwe angaphandle.
6.Intle kwaye inesisa:
I-aluminiyam i-alloy die-casting shell, ilungile kwaye igudileyo, amandla aphezulu kunye nokumelana nokunxiba: i-alloy yobhedu ekhethekileyo yevili lembungu, ukomelela okuphezulu, ukuxhathisa okulungileyo.
7.Isiqinisekiso sokhuseleko:
I-1500v ukumelana ne-voltage, i-wire lock ekhethekileyo yokutshixa umgca wentambo ilula: ukunikezelwa kombane wesigaba esisodwa, i-wiring yangaphandle ilula ngokukodwa.
8.Kulula ukuyisebenzisa:
I-oil-free kunye nebala-ihlolwe, ingenamanzi kunye ne-rust-proof, efakwe kuyo nayiphi na i-angle, isixhobo sokukhusela: umda ophindwe kabini, ukukhuselwa kokushisa, ukukhuselwa kokugqithiswa.
9.Izantya ezininzi:
Ixesha elipheleleyo lokuhamba ngamasekhondi angama-5 ukuya kwe-60, ukuhlangabezana neemfuno zeemeko ezahlukeneyo zokusebenza, iingcingo ezikhethekileyo-ezikhethekileyo: sebenzisa iingcingo ezinqanda ukushisa kwe-flame-retardant, ezingagugi xa zitshisa, kwaye zikhuselekile kwaye zithembekile.
ipharamitha yobugcisa
Ulwelo olusebenzayo: amanzi, umoya, i-oyile, ulwelo lwekhemikhali elonakalisayo
Umzekelo: iinkqubo zemibhobho yamanzi acocekileyo kunye namanzi okusela akrwada, imibhobho yokuhambisa amanzi amdaka kunye nenkqubo yogutyulo lwelindle, iinkqubo zemibhobho yamanzi acocekileyo namanzi olwandle,

Ziziphi iingcebiso zokulungisa iivalve zebhola zepvc
★ Ukuba ivalve yebhola iyavuza ngenxa yesiphatho esiyekeleyo, unokusibamba isiphatho ngevise, uze usijikelezise ngasekunene ukuqinise isiphatho.Kufuneka kuqatshelwe ukuba kufuneka uqaphele xa uqinisa isibambo, ungasebenzisi amandla amaninzi, ngaphandle koko kulula ukuphula i-valve yebhola.
★ Ukuba indawo apho i-valve yebhola ye-pvc idityaniswe kumbhobho wamanzi ayiqinile, kwaye akukho sitywina esilungileyo kwaye kukho ukuvuza kwamanzi, unokusongela i-tape yezinto ezikrwada kwindawo apho umbhobho wamanzi udityaniswe khona nebhola. ivalve, kwaye ufake ivalve yebhola emva kokujija, ukuze kungabikho kuvuza kwamanzi.
★ Ukuba ukuvuza kwamanzi kubangelwe kukuqhekeka okanye isiphene sevalve yebhola, ivalve yebhola endala kufuneka iqhaqwe, kwaye ke kufuneka kufakwe entsha.
Kufuneka kuqatshelwe ukuba i-valve yebhola ye-pvc kufuneka iqhutywe ngokuchanekileyo ngexesha lokuchithwa, kwaye la manqaku amancinci alandelayo kufuneka enziwe.
★ Emva kokuvala i-valve yebhola, kuyimfuneko ukukhulula lonke uxinzelelo kwi-valve yebhola ngaphambi kokuqhawula, ngaphandle koko isengozini.Abantu abaninzi abayihoyanga le nto.Ivalve ikhutshwa ngoko nangoko emva kokuba ivaliwe.Kusekho umlinganiselo othile woxinzelelo ngaphakathi.Le nxalenye yoxinzelelo ayikhululwa kwaye ayihambisani nokhuseleko lomntu.
★ Emva kokuba i-valve yebhola ichithwa kwaye ilungiswe, kufuneka ifakwe kwicala elichasene ne-disassembly kwaye iqiniswe kwaye igxininiswe, ngaphandle koko kuya kubakho ukuvuza kwamanzi.
Ukuba ufuna i-valve yebhola ye-pvc ihlale ixesha elide, kuyimfuneko ukunciphisa inani lokutshintsha kangangoko kunokwenzeka.Xa kukho ukuvuza kwamanzi, kufuneka ulungise ngexesha ngokweengcebiso ezintathu kwinqaku, kwaye ubuyisele ukusetyenziswa okuqhelekileyo ngokukhawuleza.
