Okwangoku, inkqubo yevalvu isetyenziswa kakhulu yiii actuators zomoya, ii-activators zombanekunye ne-electro-hydraulic actuators.Ngokweempawu ze-actuator ezintathu, sihlalutya ukusetyenziswa kwazo kwinkqubo yevalvu:

I-Pneumatic System: Inkqubo ye-pneumatic ixhomekeke kwi-Air compressor, ecinezela umoya, ihlambulule, inike i-actuator ye-pneumatic, kwaye iqhube i-valve.Igesi ikhutshwe ngokuthe ngqo kwi-atmosphere kwinkqubo yokuqhuba i-actuator, kwaye inkqubo yegesi yegesi kufuneka ijongane nomthombo wegesi ngokuqhubekayo.Ngoko ke, i-compressor yomoya ngokubanzi kufuneka isebenzise enye, indlela ehamba phambili kunye ne-activator phambi kwesebe lamacandelo okuphatha umoya, njenge-dryer, i-filter decompression, i-oil inkungu, njl. Kufuneka ukugcinwa rhoqo, ukutshintshwa.Kukho iindlela ezininzi zokudibanisa iindlela zomoya, kwaye ukuhlolwa rhoqo kuyafuneka ukukhusela ukuvuza komoya kunye nokuchaphazela uxinzelelo lwenkqubo.Umsebenzi onjalo unzima ngokwenene kuphela kukuqinisekisa ukuba inkqubo ye-pneumatic actuator kufuneka itshintshele kwisenzo esichanekileyo.I actuator yepneumatic yevalve enkulu yobubanzi, oko kukuthi, isilinda, ikhethwa ngokubanzi ngokoxinzelelo lomthombo womoya othile, kodwa i actuator yomoya kaninzi ayishukumi, okanye intshukumo ingekho, okanye intshukumo iyacotha kunye nesenzo. ayigudi Oku kubangelwe koku kulandelayo:

Xa indlela yomoya iqulethe umswakama, ukuba ubushushu bomoya bungaphantsi kwe-zero, amanzi aya kubanda, iqhwa i-actuator ye-pneumatic, ukwenzela ukuba i-actuator ye-pneumatic ayikwazi ukuhamba.

Indlela yegesi ayixutywanga yi-oyile ye-oyile, ngoko ke i-actuator ikwimeko eyomileyo ixesha elide, nto leyo ebangela ukuba ukungqubuzana kunyuke kakhulu.I-activator ixingile okanye ayikwazi kuhamba.

Uxinzelelo lwemveliso ye-compressor yomoya ayanelanga okanye kukho ukuvuza kwindlela yomoya, okubangela ukuba i-actuator ye-pneumatic ingakwazi ukufumana i-torque eyaneleyo yokuvula ivalve ngokukhawuleza okanye ivale ngokupheleleyo.

Umahluko we-coefficient yokwandiswa kwe-thermal yegesi kwindawo epholileyo kunye neshushu ikhokelela kumahluko wexesha lonke lokuhamba le-actuator ye-pneumatic.

Irhasi inokunyanzeliswa, inokubangela ukuba i-actuator ye-pneumatic iqhube kwinkqubo ukuba ingabi lula, intshukumo engalunganga ngequbuliso.

Ukuba isicelo sivalwe ngokukhawuleza, i-actuator ye-pneumatic iya kuxhotyiswa ngokubanzi ngetanki yegesi ngokwayo, kwi-Fast-off, nokuba igesi, umbane ucinyiwe, unokuqinisekisa ngokukhawuleza kunye nokuvala ivalve, kodwa ngenxa yokunciphisa i-valve. umthamo, ixesha lokuvala ngokukhawuleza aliyi kuba lifutshane kakhulu.

Inkqubo yeHydraulic: Inkqubo yesikhululo seHydraulic kunye nenkqubo yokusebenza kwegesi iyafana, idinga ukuvelisa ioyile enoxinzelelo oluphezulu, idinga isihluzo se-oyile, idinga ukubeka ioyile.Umahluko kwakhona inzuzo yenkqubo ye-hydraulic, inkqubo ye-hydraulic yi-circulation yangaphakathi, uxinzelelo lweoyile ngokubanzi malunga ne-40 ~ 120 kg, i-actuator ye-hydraulic incinci kakhulu kune-actuator ye-pneumatic, kwaye ioli ye-hydraulic ayinayo i-compressibility cylinder cylinder esebenzayo. kakuhle ayizukwenzeka i-jam jitter phenomenon.Inkqubo ye-hydraulic inokusombulula ngokupheleleyo ukunqongophala kwe-pneumatic system.

Inzuzo yenkqubo ye-hydraulic ngokwayo kukuqinisekisa ukusebenza okuthembekileyo kwe-valve yeyona ndlela ingcono kakhulu, kodwa ioli yoxinzelelo oluphezulu, njengokugcinwa okungafanelekanga, ukuvuza kweoli kuya kwenzeka rhoqo.Amacandelo enkqubo ye-Hydraulic efana ne-servo valves, izihlungi, iipayipi zoxinzelelo oluphezulu, ezifana neendleko eziphezulu, iindleko eziphezulu zokugcina.

I-actuator yombane: i-actuator yombane ihluke ngokupheleleyo kwi-actuator ye-pneumatic kunye ne-hydraulic actuator, i-actuator yombane ikhululekile ngokupheleleyo kwi-air compressor kunye nesikhululo se-hydraulic, idinga kuphela ukufumana umbane kunye nomqondiso wokuqhuba inkqubo yokudlula.Xa kuthelekiswa nenkqubo ye-pneumatic kunye ne-hydraulic system, i-actuator yombane ihlangene, kulula ukuyifaka, kwaye umsebenzi wokulondoloza uyancipha kakhulu.
