Intshayelelo kwiiValve zeBhola zoMbane
Iivalvu zebhola zombaneimele inkqubela phambili ebalulekileyo kulawulo lwanamhlanje lokuhamba komzi-mveliso, idibanisa ukusebenza okuthembekileyo kwekota-turn yeivalvu yebholangezakhono zokuchaneka kunye nokuzisebenzela ngokuzenzekelayo ze-actuator yombane. Ezi valves zizinto ezibalulekileyo kwiinkqubo ezifuna ukusebenza kude, inkqubo yokuzenzekela, okanye ukuhlanganiswa kwiinkqubo zolawulo ezintsonkothileyo. Esi sikhokelo sibanzi sihlola imigaqo yokusebenza, uyilo loyilo, ukukhethwa kwamacandelo, kunye nokusetyenziswa okwahlukeneyo kweevalvu zebhola zombane kumashishini ahlukeneyo, kubonelela iinjineli kunye neengcali zobugcisa ngolwazi olufunekayo ukwenza izigqibo zokukhetha ezinolwazi.
Umgaqo Wokusebenza: Indlela Eyintloko
Ukusebenza okusisiseko kwevalvu yebhola yombane kugxile kwisenzo sayo sokujikeleza esingama-90 degrees. Icandelo eliphambili levalvu liyinxalenye yokuvalwa okungqukuva (ibhola) enembobo ejikelezayo kwi-axis yayo. Xa imbobo ihambelana necala lombhobho, imidiya ihamba ngokukhululekileyo; xa ijikeleziswa ngama-90 degrees, umphezulu oqinileyo ongqukuva uvala indlela yokuhamba ngokupheleleyo.
Lo mgaqo ulula kodwa osebenzayo uphuculwa ngokusebenzisa umbane ozenzekelayo:
* Ukuhlanganiswa kwe-Actuator:I-actuator yombane ifumana imiqondiso yokulawula (ngesiqhelo i-4-20 mA okanye i-0-10 V DC) evela kwinkqubo yokulawula. Ezi miqondiso ziyalela i-actuator ukuba ijikelezise ibhola kwiindawo ezithile.
* Ukuhanjiswa kweGear:Injini ye-actuator iqhuba uloliwe wegiya oguqula amandla ombane abe kujikelezo oluchanekileyo loomatshini, nto leyo enika i-torque efunekayo ukuze ivalvu isebenze ngokuthembekileyo.
* Impendulo yesikhundla:Iivalvu zebhola zombane zanamhlanje ziquka iindlela zokuva indawo ezibonelela ngempendulo ngexesha langempela kwiinkqubo zolawulo, ziqinisekisa ukuba ivalvu ivuliwe ngokupheleleyo, ivaliwe ngokupheleleyo, okanye ikwindawo ephakathi.
Olu dibaniso lobuchule boomatshini kunye nolawulo lombane lwenza iivalvu zebhola zombane zibe luncedo kakhulu kwiinkqubo ezizenzekelayo apho ukusebenza ngesandla kungenzeki okanye kungenakwenzeka.
