Khangela ivalve yokuphefumla: imbonakalo kunye Scope

Khangela ivelufa ngokuba umoya ijolise kokuyeka xa anoomatshini bokungenisa lokuhamba lomoya reverse xa fan ivuliwe. Xa inkqubo yokungena icinyiwe, awukwazi ukuvumela sicatshulwa zezulu abandayo kwisithuba ongaphandle ngomzila zeemoto, ukongeza, kuba ivumela umoya khusalekileyo esuka zingene midges, uthuli kunye nezinye izinto.

Khangela ivalve yokuphefumla ingafakwa nkqo okanye tye, kuxhomekeke imisebenzi ziphambi kwakhe. Ukuba efakwe kwindawo nkqo, ngoko ke kubalulekile ukuba sihlale sikhumbula ukuba umoya flow ulwalathiso kufuneka ukusuka ezantsi ukuya phezulu. Kuba ezifuna tyaba, kubalulekile ukuba isantya sokuqukuqela yayiziimitha ngaphezu ezintandathu ngomzuzwana, ngelixa nkqo - ngaphezulu kwe ezine.

Khangela ivalve ngokuba umoya na uhlobo iincakuba zixhonywe imigodi wazibeka izindlu. Xa axis i counterweight zezindlu eqhotyoshelweyo ekwaziyo nilime xa yabe fan kwindawo evaliweyo, elikuvumela ukuba ukuvula i kakhulu kakuhle xa ukungena komoya iqala ukusebenza kwayo. Le flanges kokuxhuma zibonelelwa elisecaleni ivelufa standardly bebekwe ngokwahlukeneyo omnye imingxuma, ezilungiselelwe ukubekwa kwayo kwityhubhu ngqwabalala okanye duct.

Khangela umba ukuze uveze, ixabiso apho efumaneka lula, unokuba ngomnye iintlobo ezimbini abe icandelo cross ngokohlobo isangqa okanye uxande. Uhlobo uqhelekileyo uhlobo ngeenxa "ibhabhathane". Yesakhiwo apho iperi isithinzi axis esisigxina leyo uwahlule ivalve ibe ziinxalenye ezimbini. Air njengamaza kwicala elinye kuphela ukususela langutela ngokukhethekileyo wamanzi-zilayishwe. Ukuba umlambo ithunyelwe umva, ukuba zivaliwe. Kulo mzekelo, kukho ethile enkulu: amathuba ephezulu jamming ngenxa qa kwenye zithuba.

Ivelufa check umoya kuba umoya ingasetyenziswa kwiinkqubo zeemoto ekhaya. Ngamanye amaxesha umzobo kwi lokuhlambela kwezi zokuhlala ezimelene ayivuzi ivumba. Kulo mzekelo, indlela elikhulu liphuma imeko isenokuba ukufakelwa zeemoto lwezivalo. Akathabatheli umoya ovela shaft umoya enikwe kwi gumbi, ukuba fan icinyiwe. Xa yasebenza, ukungena komoya kuya kwenzeka kwizikhondo ejection.

Njengoko ivelufa itshekhi isoloko isetyenziswa inertia wobhedu imvelaphi inyuselwa khona ngaphandle. nesakhiwo sayo sijoliswe kwi ithuba ukuvula siyabamfamekisa kwicala elinye kuphela, ngoko ke ukuba ukhubaze ukwesona iza kuvalwa. Kufuneka kuqatshelwe ukuba iimeko ezithile yokusebenza kungakhokelela ekubeni nkqu grille inertial luncangathi. Kufuneka siqwalasele lo mba xa ukuqulunqa umoya. Nenkqubo ilungelo lo mba nga ezizuze iziphumo ezigqwesileyo.

Ngenxa yoko, ivelufa yokukhangela ukuze umoya ukwazi iqwalaselwe njenge isakhiwo isixhobo eqhelekileyo elula ngokwaneleyo ngohlobo nokuba emkhusaneni inertial. Ilungu uhlobo oluthile kufuna iimeko ezizodwa for obandayo icebo.
