Ke 'ano o ka valve proportional

ʻO ka hoʻokaʻawale ʻana e like me ka mode control valve proportional e pili ana i ka hoʻokaʻawale ʻana e like me ke ʻano hoʻololi uila a me ka mīkini hoʻololi i loko o ka pahu hoʻokele pilote o ka valve proportional, a ʻo ka ʻāpana mana uila he ʻano ʻano like ʻole e like me ka proportional electromagnet, torque motor, DC. servo motor, etc.

(1) ʻAno Electromagnetic

ʻO ke ʻano electromagnetic e pili ana i ka valve proportional me ka hoʻohana ʻana i ka electromagnet proportional ma ke ʻano he mea hoʻololi uila-mechanical, a hoʻohuli ka electromagnet proportional i ka hōʻailona o kēia manawa i ka ikaika a me ka neʻe ʻana i ka puka hōʻailona mechanical.A laila e hoʻomalu i ke kaomi, kahe a me nā ʻāpana kuhikuhi.

(2) ʻAno uila

ʻO ke ʻano uila e pili ana i ka valve proportional me ka hoʻohana ʻana i ka motor servo DC e like me ka mea hoʻololi uila-mechanical hoʻololi, a na ka DC servo motor e hoʻokomo i ka hōʻailona uila.E hoʻohuli i ka wikiwiki o ka neʻe ʻana, a laila ma o ka nut screw, gear rack a i ʻole gear reduction device CAM a hoʻololi i ka mīkini, ka mana hoʻopuka a me ka neʻe ʻana, ka mana hou o nā ʻāpana hydraulic.

(3) electrohydraulic

ʻO ke ʻano electro-hydraulic e pili ana i ka valve proportional me ke ʻano o ka torque motor a me ka nozzle baffle e like me ke kahua hoʻokele pilote.E hoʻokomo i nā hōʻailona uila like ʻole i ka motika torque, a me ka neʻe ʻana a i ʻole ka neʻe ʻana i ka angular ma o ka baffle i pili pū me ia (i kekahi manawa ʻo ka armature o ka motika torque ka baffle), e hoʻololi i ka mamao ma waena o ka baffle a me ka nozzle, i hiki ai ke kū i ke kahe o ka aila. Hoʻololi ʻia ka nozzle, a laila hoʻomalu i nā ʻāpana hoʻokomo
