Ukukhetha ivalve yebhabhathane, isikhokelo sokusetyenziswa ngokufanelekileyo kunye nokugcinwa

Iivalvu zebhabhathane zizixhobo zokulawula ukuqukuqela kwekota ezisebenzisa idiskhi yesinyithi ejikeleza kwi-axis yesiqu esisigxina. Ziivalvu ezikhawulezayo zokulawula ukuqukuqela ezivumela i-90 degrees of rotation ukuba ihambe ukusuka ekuvulekeni ngokupheleleyo ukuya kwindawo evaliweyo. Xa i-disc i-perpendicular kwi-centerline yombhobho, i-valve isendaweni evaliweyo.Xa i-disc ihambelana ne-centerline yombhobho, i-valve iya kuvuleka ngokupheleleyo (ivumela ukuhamba kwamanzi amaninzi). indlela yokulawula (idiski) iphantse ilingane nobubanzi bangaphakathi bombhobho osecaleni. Ezi zivalo ziza ngobukhulu obahlukeneyo kunye noyilo olumisela ukusebenza kwabo kwizicelo zenkqubo yoshishino; izicelo zevalvu yococeko; iinkonzo zomlilo; iinkqubo zokufudumeza, umoya, kunye ne-air conditioning (HVAC); kunye ne-slurries.Ukuthetha ngokubanzi, iivalve zebhabhathane zibalulekile kulawulo lokuhamba kunye nokuhlukaniswa kokuhamba. Intshukumo yediski iqala, icotha okanye imise ukuhamba kolwelo.Izicelo ezifuna ukuchaneka okuphezulu zixhomekeke kwiivalvu zebhabhathane ezisebenzayo ezibeka iliso kwiimeko zemibhobho, ukuvula okanye ukuvala ivalve njengoko kuyimfuneko ukugcina umyinge wokuhamba okufanayo. enye yezi mpawu zilandelayo zokuhamba: • Phantse umgca - isantya sokuhamba silingana nentshukumo ye-angular yediski. iivalve butterfly ukusebenza. • Ukuvuleka okukhawulezayo - Olu phawu lokuhamba lubonakaliswa xa kusetyenziswa iivalve zebhabhathane ezomeleleyo.Isantya sokuqukuqela kolwelo siphezulu xa idiski ihamba isuka kwindawo evaliweyo. Njengoko ivalve isondela kwindawo evuleke ngokupheleleyo, ukuqukuqela kuyehla ngokuthe ngcembe kukho utshintsho oluncinane. • Ukwahlulwa kokuqukuqelayo -Iivalvu zebhabhathane zinokubonelela ngenkonzo yokuvula/yokuvala ulwelo.Ukwahlulwa kokuqukuqela kuyafuneka nanini na indawo ethile yesixokelelwano semibhobho ifuna ukulungiswa. Iivalve zebhabhathane zifanelekile kwizicelo ezahlukeneyo ngenxa yoyilo lwazo olukhaphukhaphu kunye nokusebenza ngokukhawuleza.Iivalve zebhabhathane ezithambileyo zilungele ubushushu obuphantsi, izicelo zoxinzelelo oluphantsi, ngelixa iivalve zebhabhathane ezihleli ngentsimbi zinesakhono sokutywina xa zibamba iimeko zolwelo olurhabaxa.Le nkqubo iyasebenza. kumaqondo obushushu aphezulu kunye noxinzelelo kwaye ihambisa ulwelo olubonakalayo okanye oludlekayo.Iinzuzo zevalvu yebhabhathane zibandakanya: • Ulwakhiwo olukhaphukhaphu kunye nolubambeneyo - Ivalve yebhabhathane isebenzisa idiski yentsimbi ebhityileyo njengendlela yokulawula ukuhambahamba.Iidiski zincinci kwaye zithatha indawo encinci, kodwa zomelele ngokwaneleyo ukulawula ukuhamba kwamanzi. Ezi zivalo zinomzimba ohlangeneyo ozenza zilungele ukusetyenziswa kwiinkqubo zemibhobho kwiindawo ezimxinwa. kunevalve yebhola yobukhulu obufanayo kuba itya imathiriyeli encinci ukuyivelisa. • Utywino oluKhawulezayo noluSebenzayo - Iivalvu zebhabhathane zibonelela ngokutywinwa ngokukhawuleza xa zisebenza, zizenza zilungele ukusetyenziswa kokuhamba okuchaneka okuphezulu. iya kubonelela ngokutywinwa okwaneleyo kwezicelo zoxinzelelo oluphantsi - ukuya kuthi ga kwi-250 yeepounds nge-intshi yesikwere (psi).Ivalve yokucima i-double inika ukutywinwa okugqwesileyo kweenkqubo ukuya kuthi ga kwi-1,440 psi. • Ukuhla koxinzelelo oluphantsi kunye nokuBuyiselwa koxinzelelo oluphezulu - iivalvu zebhabhathane zinexinzelelo oluphantsi nangona idiski isoloko ikhona kulwelo.Uxinzelelo oluphantsi loxinzelelo lubalulekile ekulawuleni ukumpompa kunye neemfuno zamandla zesixokelelwano.Iivalve zebhabhathane ziyilelwe ukuvumela Ulwelo lokubuyisela amandla ngokukhawuleza emva kokuba luyishiyile ivalve. • Iimfuno zogcino oluphantsi -Iivalvu zebhabhathane zineenxalenye zangaphakathi ezimbalwa.Azinazo iipokotho ezinokubamba ulwelo okanye inkunkuma, ke ngoko, zifuna ungenelelo logcino oluncinci.Ufakelo lwazo lulula njengoko lufuna ukucinezela phakathi kweeflange zemibhobho ekufutshane.Akukho nkqubo yofakelo inzima yokufakela. ezifana nokuwelda iyafuneka. • Umsebenzi olula - Ngenxa yobukhulu bawo obubambene kunye nobunzima obulula, iivalvu zebhabhathane zifuna itorque encinci ukusebenza. ukubonelela ngetorque eyaneleyo yokusebenza kwazo. Oku kuguqulela kwiindleko zokusebenza eziphantsi - ii-actuator ezincinci zisebenzisa amandla amancinci kwaye zixabisa ngaphantsi ukongeza kwivalve. • Iivalve ze-Butterfly zichaphazeleka kwi-cavitation kunye ne-blocked flow - kwindawo evulekileyo, i-valve ayinikezeli i-port epheleleyo.Ubukho be-disc kwindlela yokuhamba kwamanzi kwandisa i-debris buildup ejikeleze i-valve, ukwandisa amandla okuba ne-cavitation.Ii-valve zebhola. Yenye indlela yezicelo zolwelo ezifuna amazibuko apheleleyo. • Ukutya okukhawulezileyo kwiinkonzo zolwelo lwe-viscous - ulwelo lugungxula izivalo zebhabhathane njengoko zihamba phakathi kwazo.Ekuhambeni kwexesha, iidiski ziye ziwohloke kwaye azisakwazi ukunika itywina.Amazinga okubola aya kuba phezulu ukuba uphatha iinkonzo ze-viscous fluid.Isango kunye nevalve yebhola inomhlwa ongcono ukuxhathisa kuneevalve zebhabhathane. • Ayilulungelanga uxinizelelo oluphezulu-ivalve kufuneka isetyenziswe kuphela xa kugutyungelwa kuxinzelelo oluphantsi, kukhawulelwe kumaqondo angama-30 ukuya kuma-80 okuvuleka. I-valve flap kwindawo evuleke ngokupheleleyo ithintela ukucocwa kwenkqubo kwaye inqande ukugquma komgca oqulethe ivalve yebhabhathane. Indawo yofakelo lwevalve yebhabhathane idla ngokuba phakathi kwee-flanges.Iivalve zebhabhathane kufuneka zifakwe ubuncinane ezine ukuya ezintandathu iidayamitha zemibhobho ukusuka kwimibhobho yokukhupha, iingqiniba, okanye amasebe ukunciphisa iziphumo zesiphithiphithi. Ngaphambi kofakelo, iipayipi zicocekile kwaye ukhangele iiflanges zokukhanya / ukuhla.Qinisekisa ukuba imibhobho ihambelana.Xa ufaka i-valve, gcina i-disc kwindawo evulekileyo.IiFlanges zingadinga ukwandiswa ukuze ugweme umonakalo kwindawo yokuhlala.Sebenzisa i-pilot. imingxuma okanye izilingi ezijikeleze umzimba wevalvu xa uphakamisa okanye uhambisa ivalve.Kuphephe ukuphakamisa ivalve kwi-actuator okanye kumqhubi wayo. Ukulungelelanisa i-valve kunye nebholi yokufaka yombhobho okufutshane.Qinisa iibholithi ngesandla, emva koko sebenzisa i-torque wrench ukuqinisa iibholithi ngokucothayo nangokulinganayo, uqikelele ukucoceka phakathi kwabo kunye neflange.Jika ivalve kwindawo evuleke ngokupheleleyo kwaye usebenzise i-torque wrench yokuqinisa iibholithi ukujonga ukuxinezeleka okulinganayo kwiibholithi. Ukugcinwa kweevalvu kubandakanya ukuthambisa amacandelo omatshini, ukuhlolwa kunye nokulungiswa kwee-activators.Iivalvu ezifuna ukuthanjiswa kwamaxesha athile ziquka izixhobo ezifakwe igrisi.Igrisi eyaneleyo ye-lithium-based grease kufuneka isetyenziswe ngamaxesha acetyiswayo ukuze kuncitshiswe irusi kunye nokubola. Kwakhona kubalulekile ukuhlola rhoqo i-actuator ukuchonga naziphi na iimpawu zokuguga okanye ukukhululeka koqhagamshelwano lombane, i-pneumatic okanye i-hydraulic enokuthi ichaphazele ukusebenza kwevalvu. Ukongezelela, umsebenzisi kufuneka ahlambulule zonke iindawo zevalve yebhabhathane kunye ne-silicone-based lubricant.Isihlalo kufuneka sihlolwe naziphi na iimpawu zokugqoka kwaye zitshintshwe xa kuyimfuneko.Iidiski ze-valve ze-Butterfly ezisetyenziswa kwizicelo ezomileyo ezifana nenkonzo yomoya ecinezelweyo ifuna ukuthambisa. Iivalvu zebhabhathane ezijikeleza ngokungaqhelekanga kufuneka ziqhutywe kanye ngenyanga. Ukukhetha iValve kunokubonakala ngathi kukhetho kunye nomsebenzi wokukhwelana, kodwa kukho iinkcukacha ezininzi zobugcisa ekufuneka ziqwalaselwe.Eyokuqala ibandakanya ukuqonda uhlobo lolawulo lwe-fluid olufunekayo kunye nohlobo lwenkonzo yamanzi. ezinye izinto ezikwaziyo ukumelana nomhlwa. Abasebenzisi kufuneka baqwalasele umthamo, uxinzelelo kunye nokutshintsha kobushushu benkqubo yombhobho kunye nenqanaba lokuzenzekelayo elifunekayo.Ngelixa iivalve zebhabhathane ezisebenzayo zibonelela ngolawulo oluchanekileyo lokuhamba, zibiza kakhulu kunezo zisebenza ngesandla.Iivalve zebhabhathane azilawuleki kwaye aziboneleli. izibuko eligcweleyo. Ukuba umsebenzisi akaqinisekanga malunga nokuhambelana kweekhemikhali zenkqubo okanye ukhetho lwe-actuation, inkampani ye-valve efanelekayo inokuncedisa ekuqinisekiseni ukhetho oluchanekileyo.
