Indlela yokukhetha ivalve yombane efanelekileyo? Uhlalutyo lweempawu zokusebenza zevalve yombane engaqhushumbayo

Indlela yokukhetha ivalve yombane efanelekileyo? Uhlalutyo lweempawu zomsebenzi wevalve yombane engaqhushumbayo ivelufa yombane kumbhobho isetyenziswa ikakhulu ukwenza ukuthintela, ukusasaza kunye nokutshintsha indlela osebenza ngayo ophakathi, ifuna kuphela ukujikelezisa idigri ezingama-90 zolawulo kunye nomzuzu omncinci wokuqengqeleka unokuvalwa. ngokuqinileyo, khetha ufakelo oluchanekileyo lombane ukuthintela i-torque incinci kakhulu, ayikwazi ukutshintsha ivalve yombane, khetha ufakelo lombane kufuneka unikele ingqalelo: I-torque yokusebenza yeyona parameter iphambili yokukhetha isixhobo sevalve yombane. I-torque ephumayo yesixhobo sombane kufuneka ibe yi-1.2 ~ 1.5 amaxesha e-torque ephezulu ye-valve yokusebenza i-tripod. Kukho ulwakhiwo ezibini eziphambili zesixhobo sevalve yombane: enye ayiqwalaselwanga ngediski yokutyhala, itorque ephuma ngokuthe ngqo; Olunye luqwalaselo lwediski yethrust, itorque ephumayo ngokutyhalela idisc stem nut kwimveliso. Inani lamakhonkco aqengqelekayo eshafti ephumayo yesixhobo sevalve yombane inxulumene nedayamitha yegama lesiqu sevalve kunye nenani lemisonto. Ibalwa ngokwe-M=H/ZS (M linani lilonke lamakhonkco aqengqelekayo ekufuneka isixhobo sombane saneliswe ngawo, H bubude obuvulayo besiqu sevalve, S yipitch yevalve stem drive thread kunye noZ linani lomsonto wesikhondo sevalve). Isiqu sedayamitha se-multi-turn type open stem valve, ukuba isixhobo sombane sivumile ukudlula isiqu esikhulu sedayamitha asikwazi ukudlula kwisikhondo sevalve yevalve, ayinakudityaniswa kwivalve yombane. Ngoko ke, i-diameter yangaphakathi ye-hollow output shaft yesixhobo sombane kufuneka ibe mkhulu kunobubanzi bangaphandle besiqu sevalve yevalve yentonga evulekileyo. Kwiivalvu zentonga emnyama kwisebe kunye neevalve ezijikelezayo ezininzi, nangona i-valve stem diameter ayifuni kuqwalaselwa, i-valve stem diameter kunye nobungakanani bendlela engundoqo kufuneka iqwalaselwe ngokupheleleyo ekukhetheni, ukwenzela ukuba indibano. inokusebenza ngokuqhelekileyo. Ukuba isantya sokuvula kunye nokuvala i-valve yesantya sokuphuma sikhawuleza kakhulu, kulula ukuvelisa i-percussion phenomenon yamanzi. Ngoko ke, isantya esifanelekileyo sokuvula kunye nokuvala kufuneka sikhethwe ngokwemiqathango eyahlukeneyo yokusetyenziswa. Uhlalutyo lweempawu zokusebenza zevalve yombane engenakugqabhuka Uhlalutyo lweempawu zokusebenza zevalve yombane engaqhushumbayo yahlulahlulwe ikakhulu ibe: ivelufa yombane engenakugqabhuka; Ivalve yombane yebhabhathane engenakudubula; Ivalve yebhabhathane engenaziqhushumbisi yombane; Ivalve yombane enefluorine engaqhumi; Ivalve yebhabhathane ekwaziyo ukuqhuma yombane; Ivalve yebhola yohlobo lweV yombane engaqhushumbayo; Ivalve yebhabhathane ethambileyo etywiniweyo yombane enobungqina bokudubula; Ivalve yebhabhathane yebhabhathane ethintela ukuqhuma kombane; Ivalve yebhabhathane yombane yolungelelwaniso olungaqhushumba; Ivalve yebhola yombane enokuqhuma kunye nokunye kubomi bangoku sele ikwindawo ethandwa kakhulu, kwaye ukusetyenziswa oku ngasentla masikwazi ukusebenza kakuhle ukuqonda kunye nokuqhelana nayo, inemisebenzi emininzi, ukuze thina Ukusetyenziswa okusebenzayo kakhulu akuyi kuzenza iimpazamo, indawo yokusetyenziswa kwayo kufuneka sinikele ingqalelo kuyo ayifanele ibekwe kwindawo yobushushu obuphezulu, kwaye ngokweyona mimandla ifanelekileyo yendawo yokusetyenziswa okusebenzayo, siyimfuneko kakhulu ukugqiba nokuqonda iimpawu ezizezakho, azinakubekwa kwilanga elithe ngqo, ukwenzela ukuba imeko yomonakalo wemeko yomatshini, okanye umgca wangaphakathi wenzeke ngaphezu kwengxaki ebangela ukusetyenziswa ngokubanzi koku kungasentla. I-actuator yombane yobungqina bokuqhuma kunye nebhola yevalve yebhola, i-actuator ithatha uyilo oludibeneyo, igalelo le-220V unikezelo lwamandla lunokuba ngokuthe ngqo ekutshintsheni uhlengahlengiso lobungakanani, kunye nemodyuli eyakhelweyo ye-servo, isignali yokulawula igalelo (4 ~ 20mADC okanye 1 ~ 5VDC) kunye ne-single- amandla esigaba anokulawula ukusebenza. Ivalve yebhola yombane ekwaziyo ukuqhuma ibakala i-dⅡBT4, ibakala lokhuseleko le-IP67, elinesixhobo sokulawula intsimi. Ivalve yebhola yokuqhuma kombane ibonakala ngoku: akukho mandla, isiphatho se-clutch sinokusebenza ngesandla. Xa inikwe amandla, i-clutch iphinda izise ngokuzenzekelayo. Umkhombandlela wokuhamba unokuba yinto engafanelekanga, uluhlu olulungelelaniswayo, lunokusetyenziselwa uxinzelelo oluphezulu kunye nezihlandlo ezinkulu zobubanzi, ukulawula i-viscosity ephezulu, kunye nefiber kunye ne-fine particle media. Ivalve yebhabhathane elingagqabhuki ngombane yenziwe ngeevalve ezintathu zebhabhathane eccentric kunye neactuator yombane. Ifom ye-valve ye-butterfly enobungqina bombane: isakhiwo se-eccentric ezintathu kunye nesakhiwo esisodwa se-eccentric, ifom yokutywina: itywina lesinyithi kunye nesakhiwo sokutywinwa esithambileyo. Ivalve yebhabhathane enobungqina bokuqhambuka kombane yahlulwe yaba ziindidi ezimbini: uhlobo lweflange kunye nodidi lwebamba. Kwiqondo lobushushu elingaphantsi kwe-150 degrees inokukhethwa PTFE ivalve yebhabhathane yetywina, iimeko zobushushu obuphezulu zinokukhethwa ezintathu eccentric hard valve valve umzimba. Ivalve yebhabhathane elawulayo yombane enokuqhushumba ingasetyenziswa ngokubanzi ekutyeni, ekukhuselweni kwendalo, kushishino lokukhanya, i-petroleum, ishishini lemichiza, izixhobo zokufundisa, ukwenza iphepha, amandla ombane kunye namanye amashishini enkqubo yolawulo oluzenzekelayo yoshishino. Ivalve yebhabhathane engagqabhukiyo yombane ekutyeni, amayeza, imichiza, i-petroleum, amandla ombane, i-textile, iphepha kunye nolunye unikezelo lwamanzi kunye ne-drainage, umbhobho werhasi wokulawula ukuhamba kunye nokudibanisa phakathi. Ngaba uyayazi indlela yokusebenzisa ngokuchanekileyo ivalve yombane yokuthintela uqhushumbo ukuze ubomi kunye nokusebenza kwesixhobo kusetyenziswe kakuhle? Ukuba awuyazi, nantsi indawo yokukroba. 1. Ukuba usebenzisa iivalvu zombane ezingagqabhukiyo, kufuneka uqale uqinisekise ngokuphindaphindiweyo ukuba zonke izakhiwo nomhlaba zihambelana enye kwenye phambi kokuba ubaleke. Abathengi abaninzi bachaphazelekayo ngokuhlolwa okungakhathaliyo, okuchaphazela ubomi benkonzo kunye nomsebenzi wezixhobo. I-2, emva kokusebenza kwe-valve yombane yobungqina bokuqhuma, ungabi nzima kakhulu ukulawula izixhobo, kodwa ngokukhawuleza ukulawula ukuba amandla angaphandle makhulu kakhulu, akakwazi ukwandisa umsebenzi wesixhobo uya kwenza iinxalenye ze izixhobo ngenxa yamandla amaninzi angaphandle kunye nokuphazamiseka, ngaloo ndlela kuchaphazela izixhobo. Iimpawu zomsebenzi we-valve yombane yobungqina bokuqhuma: i-1, iphucula i-predecessor yetekhnoloji yokudibanisa i-pin, ukwenzela ukuba umsebenzi wokutywina unokwethenjelwa ngakumbi, ubomi benkonzo ende, ukugcinwa okulula kwe-2, ukusetyenziswa kwe-electroplating, inayiloni kunye nezinye iingubo ezahlukeneyo, ukumelana nokugqwala. iphuculwe, inokuhlangabezana neemfuno zemigodi eyahlukeneyo. 3, inkangeleko yevalve usebenzisa isitshizi ukutyabeka, ukuze imveliso inkangeleko umsebenzi anticorrosion inkqubela, inkangeleko entle. I-4, umsebenzi wesixhobo sokuqhuba umbane, iimpawu zayo zezi zilandelayo: 1) Incinci kwaye ilula, kulula ukuyichitha kunye nokulungiswa, kwaye inokufakwa kuyo nayiphi na i-Angle 2) Igobolondo le-aluminium i-alloy die-cast inokunciphisa ukuphazamiseka kwe-electromagnetic 3) Uyilo oludibeneyo lwe-worm. I-shaft ye-gear output ukuphepha i-gap yoxhumo oluphambili kunye nokuchaneka okuphezulu kwe-4) I-shaft ephumayo ye-worm gear ephoswe nge-alloy yobhedu inamandla aphezulu kunye nokumelana nokunxiba kakuhle 5) I-Microswitch ngokungena ngokupheleleyo, i-agile ngakumbi kwaye ivaliwe, ikhuselekile ngakumbi sebenzisa i-6) Imiqondiso eyahlukeneyo yokuphuma: uhlobo lokutshintsha, uhlobo lomlawuli, uhlobo oluhlakaniphile lwe-7) Ngokhuseleko olushushu, umsebenzi wokukhusela umthwalo, ukhuseleko luqinisekisiwe.
