Zithini iiValve zePneumatic Actuator

Iivalvu ze-Actuator ze-Pneumatic, ezidla ngokubizwa ngokuba ziivalvu zomoya, zizixhobo zokulawula ulwelo oluzenzekelayo ezisebenza ngomoya ocinezelweyo. Zisebenzisa i-actuator yomoya ukuvula, ukuvala, okanye ukuguqula ukusebenza kwevalvu, okuvumela ulawulo oluchanekileyo lokuhamba, uxinzelelo, kunye nobushushu beegesi, ulwelo, kunye nomphunga kwiipayipi. Xa kuthelekiswa neevalvu zemveli, iValve yePneumatic Actuator inika amaxesha okuphendula akhawulezayo, ukusebenza okulula, kunye nokukwazi ukulawula kude, okwenza ukuba zilungele iindawo ezinzima, ukusetyenziswa rhoqo, kunye neenkqubo ezizenzekelayo ezifuna ukungenelela okuncinci komntu.

Indlela iiValve zePneumatic Actuator ezisebenza ngayo

Iivalvu ze-Pneumatic Actuator zisebenza ngokomgaqo "wokusebenza koomatshini okuqhuba uxinzelelo lomoya." Le nkqubo ibandakanya amanyathelo amathathu abalulekileyo:

1. Ukwamkelwa kweSignali:Inkqubo yokulawula (umz., i-PLC okanye i-DCS) ithumela isignali yomoya (ngesiqhelo i-0.2–1.0 MPa) ngemigca yomoya ukuya kwi-actuator.
2. Ukuguqulwa kwamandla:Ipiston okanye idiaphragm ye-actuator iguqula amandla omoya acinezelweyo abe ngamandla oomatshini.
3. Ukusebenza kweValve:La mandla aqhuba i-valve core (umz., ibhola, idiski, okanye isango) ukuba ijikeleze okanye ihambe ngomgca, ilungisa ukuhamba okanye ivale i-medium.
   Iivalvu ezininzi zePneumatic Actuator ziquka iindlela zokubuyisela i-spring ezibuyisela i-valve kwindawo ekhuselekileyo ngokuzenzekelayo (ivuleke ngokupheleleyo okanye ivaliwe) ngexesha lokungasebenzi komoya, nto leyo ephucula ukhuseleko lwenkqubo.

Izinto eziphambili zePneumatic Actuator Valves

Iivalvu ze-Actuator ze-PneumaticZiqulathe izinto ezintathu eziphambili ezisebenzisana ukuqinisekisa ulawulo olusebenzayo lolwelo.

Isixhobo sokuqhuba umoya

I-actuator ngumthombo wamandla we-Pneumatic Actuator Valve, eguqula uxinzelelo lomoya lube yintshukumo yoomatshini. Iindidi eziqhelekileyo ziquka:
