Pneumatic diaphragm igenga valve
Urashobora kumenya amakuru amwe yerekeranye na valve igenga izina ryayo. Ijambo ryibanze "amabwiriza" nuko urwego rwacyo rushobora guhinduka uko bishakiye hagati ya 0 na 100%.
Inshuti witonze zigomba gusanga hari igikoresho kimanitse munsi yumutwe wa buri valve igenga. Ababimenyereye bagomba kumenya ko uyu ariwo mutima wa valve igenga, umwanya wa valve. Binyuze muri iki gikoresho, amajwi yinjira mu mutwe (firime pneumatike) arashobora guhinduka. Kugenzura neza umwanya wa valve.
Imyanya ya Valve irimo imyanya yubwenge hamwe nubukanishi. Uyu munsi turaganira kumwanya wanyuma wubukanishi, ni kimwe nu mwanya werekana ku ishusho.
Ihame ryakazi ryimashini ya pneumatike ya valve umwanya
Valve imyanya yububiko
Ishusho isobanura ahanini ibice bigize imashini ya pneumatike ya valve umwanya umwe umwe. Intambwe ikurikira nukureba uko ikora?
Inkomoko yumwuka iva mu kirere gifunitse cya sitasiyo yo guhumeka ikirere. Hariho akayunguruzo ko mu kirere kagabanya valve imbere yisoko yumwuka winjira mumwanya wa valve kugirango usukure umwuka wafunzwe. Inkomoko yumwuka uva hanze yumuvuduko ugabanya valve yinjira mumwanya wa valve. Ingano yumwuka winjira mumutwe wa valve igenwa ukurikije ibimenyetso bisohoka mugenzuzi.
Ibimenyetso by'amashanyarazi bisohoka mugenzuzi ni 4 ~ 20mA, naho ibimenyetso bya pneumatike ni 20Kpa ~ 100Kpa. Guhindura kuva mumashanyarazi kugera kubimenyetso bya pneumatike bikorwa binyuze mumashanyarazi.
Iyo ibimenyetso byamashanyarazi bisohoka mugenzuzi bihinduwe mubimenyetso bya gaze bihuye, ibimenyetso bya gaze bihinduka noneho bigakorerwa kumurongo. Lever 2 izenguruka kuri fulcrum, naho igice cyo hepfo ya lever 2 kigenda iburyo cyegera nozzle. Umuvuduko winyuma wa nozzle uriyongera, kandi nyuma yo kongererwa imbaraga na pneumatic amplifier (ibice bifite ikimenyetso kiri munsi yikimenyetso ku ishusho), igice cyisoko ryikirere cyoherezwa mubyumba byikirere bya diaphragm ya pneumatike. Igiti cya valve gitwara intoki hasi hanyuma ihita ifungura buhoro buhoro. kuba muto. Muri iki gihe, inkoni yo gutanga ibitekerezo (inkoni izunguruka ku ishusho) ihujwe nigiti cya valve igenda ikamanuka ikikije umuzenguruko, bigatuma impera yimbere yizengurutsa ikamanuka. Kamera ya eccentric ihujwe nayo izunguruka ku isaha, naho uruziga ruzunguruka ku isaha kandi rwerekeza ibumoso. Kurambura ibitekerezo. Kuva igice cyo hepfo cyibitekerezo isoko irambura leveri 2 ikagenda ibumoso, izagera ku mbaraga zingana hamwe nigitutu cyikimenyetso gikora ku nzogera, bityo valve igashyirwa kumwanya runaka kandi ntigenda.
Binyuze mu ntangiriro yavuzwe haruguru, ugomba kuba ufite gusobanukirwa neza na mashini ya valve ihagaze. Iyo ufite amahirwe, nibyiza kuyisenya rimwe mugihe uyikora, kandi wongere umwanya wa buri gice cyumwanya hamwe nizina rya buri gice. Kubwibyo, ikiganiro kigufi cyibikoresho bya mashini biza kurangira. Ibikurikira, tuzagura ubumenyi kugirango dusobanukirwe byimbitse kugenzura amabwiriza.
