Ivalvu yokulawula isihlalo esisodwa sikagesi

I-valve yokulawula isihlalo esisodwa sikagesi i-valve yokulawula isihlalo esisodwa esiphezulu esiphezulu, enezici zesakhiwo esilula, ukusebenza kahle kokuvala uphawu, izinga lokugeleza okukhulu nokusetshenziswa okuthembekile. Uhlelo olusebenzayo nolwanele lwesiqondiso esiphezulu lunqoba ukudlidliza lapho ukuvulwa kukuncane, futhi impilo yesevisi ephumelelayo yinde.

Ivalvu yokulawula isihlalo esisodwa kagesi iqukethe i-actuator kagesi kanye nevalvu yokulawula enesihlalo esisodwa. Kukhona uhlelo lwe-servo ku-actuator kagesi, asikho isidingo sokuhlonyiswa nge-servo amplifier, isignali yokufaka namandla angalawula ukusebenza, uxhumano lulula, i-spool yomshini olawulayo ithatha umhlahlandlela ophezulu, ofaneleka kakhulu izidingo eziqinile zokuvuza, futhi umehluko wengcindezi phakathi kwengaphambili nangemuva kwe-valve uphansi. , Futhi kukhona i-viscosity ethile kanye nemidiya equkethe i-fiber.

Izici ze-valve yokulawula isihlalo esisodwa sikagesi:

1. Ukuvela kwe-valve yokulawula isihlalo esisodwa sikagesi kusemuva kune-valve yokulawula umoya, kodwa ububanzi bokusetshenziswa kwayo bukhulu kakhulu. Ngenxa yokuthi awukho umthombo womoya odingekayo, kulula kakhulu ukuyifaka nokusebenzisa, futhi ingasebenza inqobo nje uma ukunikezwa kwamandla nesignali yokulawula kuxhunyiwe.

2. I-valve yokulawula isihlalo esisodwa sikagesi ithatha isakhiwo somzimba we-valve elinganiselayo, esinamandla amancane angenakulinganisa we-axial, umehluko omkhulu ovunyelwe wokucindezela kanye nokuzinza okuhle.

3. Umkhono ushintshashintsha kakhulu, kulula ukuwuhlanganisa nokuwuhlakaza, futhi kulula ukuwunakekela.

4. I-valve yokulawula kagesi yakhiwe izingxenye ezimbili: i-actuator kagesi kanye ne-valve yokulawula. Ama-activator kagesi anezinhlobo ezimbili ze-linear stroke kanye ne-angular stroke, ehlanganiswe namavalvu okulawula ukushaywa kwe-angular ngokulandelanayo. Isibonelo, ama-valve okulawula isihlalo esisodwa, ama-valve okulawula izihlalo ezimbili, ama-sleeve control valve, njll.
