Chinhu chikuru chinoshandiswa nepneumatic actuator ndichovharuvhu inogadzirisaChinoisa positi. Chinoshanda pamwe chete ne pneumatic actuator kuwedzera simba rekunyatsoona nzvimbo yevharuvhu, gadzirisa mhedzisiro yesimba risina kuenzana uye kukweshana kwemudziyo, uye ita shuwa kuti vharuvhu inopindura chiratidzo chemutongi. svika panzvimbo yakakodzera.

Mamiriro anotevera anoda kuti pave nechinhu chinotsvaga ruzivo:
Kana kumanikidzwa kwepakati nepakati kwakakwira uye paine musiyano mukuru wekumanikidzwa; 2. Kana caliber yevharuvhu inotonga yakakura (DN>100);
3. Vharuvhu inodzora tembiricha yakakwira kana yakaderera;
4. Kana zvichikosha kukurumidzisa basa revharuvhu rinodzora;
5. Kana zviratidzo zvakajairwa zvichishandiswa kufambisa ma actuator ane ma spring ranges asina kujairika ( spring ranges dziri kunze kwe20-100KPa);
6. Pose panoshandiswa kudzora kupatsanurana kwenzvimbo;
7. Kana vharuvhu yatendeutswa, nzira dzekuvhara mhepo nedzekuvhura mhepo dzinochinjana;
8. Kana kamera yekuisa positi ichifanira kuchinjwa kuitira kuti ichinje hunhu hwekufamba kwevharuvhu;
9. Kana paine chiito chakaenzana, hapana piston actuator kana spring execution mechanism;
10. Mavharuvhu emagetsi-pneumatic anofanira kugoverwa kana uchishandisa masaini emagetsi kudzora maactuator emhepo.

Vharuvhu yemagetsi: Vharuvhu yesolenoid inofanira kuiswa musystem kana chirongwa chekutonga kana kuti nzvimbo mbiri dzichidiwa. Kudyidzana pakati pevharuvhu yesolenoid nevharuvhu inotonga kunofanira kufungwa nezvazvo pakusarudza vharuvhu yesolenoid pamwe chete nesosi yemagetsi yeAC neDC, voltage, uye frequency. Inogona kuva nekushanda "kwakavhurika kazhinji" kana "kwakavharika kazhinji".
Mavharuvhu maviri esolenoid anogona kushandiswa panguva imwe chete kana zvichidikanwa kuwedzera kugona kwevharuvhu yesolenoid kuitira kuderedza nguva yekushanda, kana kuti vharuvhu yesolenoid inogona kushandiswa sevharuvhu yepilot pamwe chete nepneumatic relay ine simba guru.

Pneumatic relay: Pneumatic relay imhando yepower amplifier inogona kuendesa chiratidzo chekumanikidzwa kwemhepo kunzvimbo iri kure kubvisa lag inokonzereswa nekupararira kwepombi yechiratidzo. Pakati pe regulator ne field regulating valve, pane rimwe basa rekuwedzera kana kuderedza kuwedzera kwechiratidzo. Inonyanya kushandiswa pakati pe field transmitter ne regulator device iri mu central control room.

chishanduri:
Chinoshandura magetsi chakakamurwa kuita chinoshandura magetsi negesi uye chinoshandura magetsi negesi. Basa rayo nderekushandura hukama huripo pakati pemasaini emagetsi negesi. Chinonyanya kushandiswa kushandura 0~10mA kana 4~20mA kana 0 ~ 100KPa kuita signal yemagetsi ye0 ~ 10mA kana 4 ~ 20mA.

chinodzora mafirita emhepo:

Chinhu chinoshandiswa nemidziyo yemagetsi inoshandiswa muindasitiri ivharuvhu rekudzikisa kumanikidzwa kwemhepo. Basa rayo guru nderekudzikamisa kumanikidzwa padanho rinodiwa uku uchisefa nekuchenesa mweya wakamanikidzwa unobva mucompressor yemhepo. Silinda yemhepo, michina yekupfapfaidza, masosi emhepo, uye michina yekudzikamisa kumanikidzwa kwemidziyo midiki yemhepo ndeimwe yemimwe yemidziyo yemhepo nemavharuvhu esolenoid ayo inogona kushandiswa maari.

Vharuvhu yekuchengetedza (vharuvhu inozvivharira yega)

Vharuvhu rinozvivharira roga inzira inoita kuti vharuvhu irambe iri panzvimbo yayo. Kana mhepo ikatadza kushanda, mudziyo unogona kudzima chiratidzo chemhepo kuti uchengetedze chiratidzo chekumanikidzwa kwekamuri re membrane kana cylinder padanho rayo risati rakundikana uye nzvimbo yevharuvhu padanho rayo risati rakundikana. Kudzivirira nzvimbo.

chinzvimbo chinotumira mavharuvhu
Kana vharuvhu rinodzora riri kure nekamuri rekudzora, zvinodikanwa kuti pave nechinhu chinotumira nzvimbo yevharuvhu, icho chinoshandura kuburitswa kwevharuvhu kuita chiratidzo chemagetsi uye chinochitumira kuimba yekudzora zvichienderana nemutemo wakafanotaurwa, kuitira kuti unzwisise nzvimbo yekuchinja yevharuvhu pasina kuenda kunzvimbo yacho. Chiratidzo chinogona kunge chiri chiratidzo chinoenderera mberi chinomiririra chero kuvhurwa kwevharuvhu kana kuti chinogona kuonekwa sekushanda kwekudzosera kumashure kwenzvimbo yevharuvhu.

Chinja chekutaurirana panguva yekufamba
Chinogumira chinja chinhu chinotumira chiratidzo panguva imwe chete uye chinoratidza nzvimbo mbiri dzakanyanya dzechinogumira chinja chezavharuvhu. Imba yekudzora inogona kutaura mamiriro echinogumira vharuvhu zvichibva pachiratidzo ichi uye kutora matanho akakodzera.
