Inqaku oza kukwazisa ngaloIivalvu zebhola zePVC
Umsebenzi wevalve yebhola yePVC
Ivalve yebhola, indawo yokuvula neyokuvala (ibhola) iqhutywa sisikhondo sevalve kwaye ijikeleza i-axis yesikhondo sevalve. Ikakhulu isetyenziselwa ukunqumla okanye ukudibanisa okuphakathi kwipayipi. Ikwasetyenziselwa ukulawula nokulawula ulwelo. Phakathi kwazo, i-valve yebhola ye-V etywinwe ngokuqinileyo ine-shear force enamandla phakathi kwe-V-shaped core kunye nesihlalo sevalve yensimbi ye-carbide enesamente. Amandla okucheba afaneleke ngakumbi kumajelo eendaba aqulethe iintsinga kunye namasuntswana aqinileyo.
Ivalve yebhola yeendlela ezininzi kumbhobho ayinakulawula kuphela ukuhlangana, ukuphambuka kunye nokutshintshela kwicala elihambayo le medium, kodwa inokuvala naliphi na itshaneli enye ukuqhagamshela amanye amajelo amabini. Le valve kufuneka ifakwe ngokubanzi ngokuthe tye kumbhobho.
Ukuhlelwa kwevalve yebhola: ivalve yebhola yepneumatic, ivalve yebhola yombane, ivalve yebhola yezandla.
Ulwazi olusisiseko
Ukusetyenziswa kwevalve yebhola ye-pvc ayigqithisi kwi-45 ℃, kwaye indawo ephakathi ayizifanelanga izinyibilikisi eziphilayo kunye nee-oxidants ezomeleleyo. Ngokwale meko, olu hlobo lwevalve yebhola lungasetyenziselwa kuphela ulwelo olungaphantsi kwe-45 ° C kwaye uxinzelelo lungaphantsi kwe-1.0mpa.
Xa kuthelekiswa nezinye iivalvu, ineenzuzo ezilandelayo.
1. Ukuxhathisa ulwelo oluphantsi
Ivalve yebhola ineyona ndlela incinci yokuxhathisa ulwelo phakathi kwazo zonke iivalvu. Nkqu nevalve yebhola yedayamitha encitshisiweyo inokuxhathisa okuncinci kakhulu. Ivalve yebhola yePVC yimveliso entsha yevalvu yebhola eyenziwe ngokweemfuno zolwelo lwemibhobho eyonakalisayo. Izinto eziluncedo kwimveliso: ubunzima obulula, ukuxhathisa okuqinileyo kwe-corrosion, i-compact kunye nenkangeleko enhle, ubunzima bomzimba obulula, ukufakwa lula, ukuxhathisa okuqinileyo kwe-corrosion, uluhlu olubanzi lwesicelo, izinto ezicocekileyo kunye ne-non-toxic, ukunxiba-resistant, kulula ukuqhawula, ukugcinwa okulula.
Ukongeza kwizinto zeplastiki zePVC, iivalve zebhola zeplastiki zikwabandakanya iPPR, iPVDF, iPPH, iCPVC, njl.
2. Ivalve yebhola yePVCinokumelana nokugqwesa okugqwesileyo.
Umsesane wokutywina wamkela F4. Ukumelana nokugqwesa okugqwesileyo kunye nokwandisa ubomi benkonzo. Ukujikeleza okuguquguqukayo kwaye kulula ukuyisebenzisa.
3. Njengevalve yebhola edibeneyo, iIvalve yebhola yePVCinamanqaku okuvuza ambalwa, amandla aphezulu, kunye nevalve yohlobo loqhagamshelo kulula ukudibanisa kunye nokuqhaqha.
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. Imisebenzi enamandla:
Uhlobo oluhlakaniphile, uhlobo olulinganayo kunye nohlobo lokutshintsha zonke zikhona, kwaye umthamo uncinci: umthamo ulingana kuphela malunga ne-35% yeemveliso ezifanayo.
5. Abantu abakhaphukhaphu nabangabizi kakhulu:
Ubunzima bumalunga ne-30% kuphela yeemveliso ezifanayo, kwaye ukusebenza kunokwethenjelwa: iibheringi kunye namacandelo ombane athunyelwa ngaphandle kweemveliso zegama legama.
6. Mhle kwaye unesisa:
Iqokobhe le-aluminiyam edibeneyo yokuphosa, ethambileyo kwaye egudileyo, amandla aphezulu kunye nokumelana nokunxiba: ingxubevange yobhedu ekhethekileyo yegiya yeentshulube, amandla aphezulu kunye nokunganyangeki kakuhle.
7. Isiqinisekiso sokhuseleko:
I-1500v yokumelana ne-voltage, i-wire lock ekhethekileyo yentambo yokutshixa ilula: unikezelo lwamandla ombane omnye, i-wiring yangaphandle ilula kakhulu.
8. Kulula ukuyisebenzisa:
Ukuhlolwa kwe-oil-free spot, i-waterproof kunye ne-rust-proof, ukufakwa kuyo nayiphi na i-angle, isixhobo sokukhusela: umda ophindwe kabini, ukhuseleko lobushushu, ukukhuselwa kokugqithiswa.
9. Izantya ezininzi:
Ixesha elipheleleyo lokuhamba li-5 ukuya kwimizuzwana ye-60, enokuthi ihlangabezane neemfuno zeemeko ezahlukeneyo zokusebenza. Intambo yomgangatho okhethekileyo yenziwe ngocingo oluchasene nokushisa kunye ne-flame-retardant, olungagugi xa lufudumala, kwaye lukhuselekile kwaye luthembekile.

Ziziphi izakhono zokugcinwa kwevalve yebhola ye-pvc
★ Ukuba ivalve yebhola iyavuza ngenxa yesiphatho esiyekeleyo, cinezela isiphatho kwivise, uze ujike isiphatho ngasekhohlo ukusiqinisa. Kufuneka kuqatshelwe ukuba kufuneka uqaphele xa uqinisa isibambo, ungasebenzisi amandla amaninzi, ngaphandle koko i-valve yebhola iya konakala lula.
★ Ukuba uxhulumaniso phakathi kwevalve yebhola ye-pvc kunye nombhobho wamanzi awuqinanga, ukutywinwa akulungile, kwaye kukho ukuvuza kwamanzi, ungasongela i-valve ye-tape yezinto ezikrwada kwindawo apho umbhobho wamanzi udibanisa ibhola, kwaye ufake. ivalve yebhola emva kokujija ukuthintela ukuvuza kwamanzi.
★ Ukuba kukho ukuvuza kwamanzi ngenxa yokuqhekeka okanye isiphene sevalve yebhola, ivalve yebhola endala kufuneka iqhaqwe kwaye iphinde ifakwe.
Kufuneka kuqatshelwe ukuba i-valve yebhola ye-pvc kufuneka iqhutywe ngokuchanekileyo xa ichithwa kwaye idibanisa, kwaye ezi ngongoma zilandelayo kufuneka zenziwe kakuhle.
★ Emva kokuba ivalve yebhola ivaliwe, lonke uxinzelelo olukwivalve yebhola kufuneka lukhutshwe ngaphambi kokuba luqhawulwe, kungenjalo ingozi ingenzeka. Abantu abaninzi abayihoyanga le nto. Hlulisa ngokukhawuleza emva kokuba ivalve ivaliwe. Kusekho uxinzelelo apho. Le nxalenye yoxinzelelo ayikhululwa, engabangeli ukhuseleko lomntu.
★ Emva kokuba i-valve yebhola ichithwa kwaye ilungiswe, kufuneka ifakwe kwicala elichasene ne-disassembly kwaye iqiniswe, ngaphandle koko iya kuvuza.
Ukuba ufuna ivalve yebhola yepvc ihlale ixesha elide, kufuneka unciphise inani lokutshintsha kangangoko. Xa kukho ukuvuza kwamanzi, kufuneka uyilungise ngexesha ngokweengcebiso ezintathu kwinqaku, kwaye ubuyele ekusebenziseni okuqhelekileyo ngokukhawuleza.
