Njengamanje, isistimu ye-valve isetshenziswa kakhulu yiama-actuator we-pneumatic, ama-actuator kagesikanye nama-electro-hydraulic actuators.Ngokwezici zama-actuator amathathu, sihlaziya ukusetshenziswa kwawo ohlelweni lwe-valve:

I-Pneumatic System: Uhlelo lwe-pneumatic luncike ku-Air compressor, ecindezela umoya, iwuhlanze, inikeze i-actuator yomoya, futhi ishayele i-valve.Igesi ikhishwa ngokuqondile emkhathini ngenqubo yokushayela i-actuator, futhi isistimu yendlela yegesi idinga ukubhekana nomthombo wegesi ngokuqhubekayo.Ngakho-ke, i-compressor yomoya ngokuvamile idinga ukusebenzisa eyodwa, umgwaqo omkhulu kanye ne-actuator ngaphambi kwegatsha lezingxenye zokuphatha umoya, njenge-dryer, i-filter decompression, inkungu yamafutha, njll. Udinga ukulungiswa okuvamile, ukushintshwa.Kunamajoyinti amaningi endlela yomoya, futhi nokuhlolwa njalo kuyadingeka ukuze kuvinjwe ukuvuza komoya futhi kuthinte ingcindezi yesistimu.Umsebenzi onzima onjalo empeleni uwukuqinisekisa kuphela ukuthi isistimu ye-pneumatic actuator idinga ukushintshela esenzweni esifanele.I-actuator ye-pneumatic ye-valve yobubanzi obukhulu, okungukuthi, isilinda, ngokuvamile ikhethwa ngokuvumelana nomfutho othile womthombo womoya, kodwa i-actuator yomoya ngokuvamile ayinyakazi, noma isenzo singekho, noma isenzo sihamba kancane futhi isenzo. ayibushelelezi Lokhu kuvame ukubangelwa yilokhu okulandelayo:

Lapho indlela yomoya iqukethe umswakama, uma izinga lokushisa lomoya lingaphansi kwe-zero, amanzi azoqhwaza, eqandisa i-actuator ye-pneumatic, ukuze i-actuator ye-pneumatic ayikwazi ukunyakaza.

Umzila wegesi awugcotshwa yinkungu yamafutha, ngakho-ke i-actuator isesimweni esomile isikhathi eside, okubangela ukungqubuzana kwande kakhulu.I-actuator ibambekile noma ayikwazi ukunyakaza.

Ingcindezi yokuphuma kwe-compressor yomoya ayanele noma kukhona ukuvuza emgudwini womoya, okwenza i-actuator yomoya ingakwazi ukuthola i-torque eyanele yokuvula i-valve ngokushesha noma ivale ngokuphelele i-valve.

Umehluko we-coefficient yokwanda okushisayo kwegesi endaweni epholile neshisa kakhulu iholela emehlukweni waso sonke isikhathi sokuhamba se-actuator yomoya.

Igesi inokuminyana, ingase ibangele ukuthi i-activator ye-pneumatic isebenze enqubeni ingabi bushelelezi, ukunyakaza okungalungile okungazelelwe.

Uma isicelo sivaleka ngokushesha, i-actuator ye-pneumatic izoba nethangi legesi ngokwalo, ekuvaleni okusheshayo, ngisho noma igesi, ugesi unqanyuliwe, usengaqinisekisa ukuvala nokuvala i-valve ngokushesha, kodwa ngenxa yomkhawulo. umthamo, isikhathi sokuvala ngokushesha ngeke sibe sifushane kakhulu.

IHydraulic System: Uhlelo lwesiteshi seHydraulic kanye nendlela yokusebenza yegesi iyafana, idinga ukukhiqiza uwoyela onengcindezi ephezulu, idinga isihlungi sikawoyela, idinga ukubeka uwoyela.Umehluko futhi inzuzo yesistimu ye-hydraulic, i-hydraulic system ukuhamba kwangaphakathi, ingcindezi kawoyela ngokuvamile imayelana ne-40 ~ 120 kg, i-hydraulic actuator incane kakhulu kune-actuator yomoya, futhi uwoyela we-hydraulic awunakho ukucindezelwa kwe-hydraulic cylinder esebenzayo. ngokushelelayo ngeke kwenzeke i-jam jitter phenomenon.Uhlelo lwe-hydraulic lungaxazulula ngokuphelele ukushoda kwesistimu ye-pneumatic.

Inzuzo yesistimu ye-hydraulic ngokwayo ukuqinisekisa ukusebenza okuthembekile kwe-valve kokukhetha okungcono kakhulu, kodwa uwoyela ophezulu wengcindezi, njengokugcinwa okungalungile, ukuvuza kwamafutha kuzovame ukwenzeka.Izingxenye zesistimu ye-Hydraulic ezifana nama-valve e-servo, izihlungi, amapayipi okucindezela okuphezulu, njengezindleko ezibizayo, zokugcinwa okuphezulu.

I-actuator kagesi: I-actuator kagesi ihluke ngokuphelele ku-actuator yomoya kanye ne-hydraulic actuator, i-actuator kagesi ikhululekile ngokuphelele ebugqilini be-air compressor kanye nesiteshi se-hydraulic, idinga kuphela ukuthola amandla kanye nesignali ukushayela uhlelo lokudlula.Uma kuqhathaniswa nesistimu ye-pneumatic kanye ne-hydraulic system, i-actuator kagesi ihlangene, kulula ukuyifaka, futhi umsebenzi wokulungisa uyancipha kakhulu.
