Abstract

FIELD: hydraulic automatic control systems. SUBSTANCE: pilot valve has control stage 1 and controlled stage 2. Gate 3 in control stage has projections 4, 5, is located between nozzles 6, 7, is installed in pilot valve housing on bands 8, 9 and is coupled with movable member of electromechanical transducer 10, with form 11 of movable coil 12 located in circular clearance 13. Nozzles 6, 7 are connected to pressure source through restrictors 14, 15 and channels 16, 17, 18, 19 communicating with end face chambers 20, 21 of spool 22. Return chamber 23 is hermetically sealed by diaphragms 24, 25 and is placed in communication with reservoir through channel 26. Gate 3 is held in neutral position by springs 27, 28. Clearance between end face surfaces can be adjusted by turning in or out along thread 31. EFFECT: enhanced reliability of servomechanism. 1 dwg

Изобретение относится к гидроавтоматике. Сервоклапан содержит управляющую 1 и управляемую 2 ступени. В управляющей ступени заслонка 3 с выполненными на ней выступами 4,5 размещена между соплами 6,7 и установлена в корпусе сервоклапана на лентах 8,9, связана с подвижным элементом электромеханического преобразователя 10, с каркасом 11 подвижной катушки 12, расположенной в кольцевом зазоре 13. Сопла 6,7 подключены к источнику давления через дроссели 14,15 и каналы 16,17,18,19, сообщающиеся с торцевыми камерами 20,21 золотника 22. Сливная камера 23 герметизирована мембранами 24,25 и сообщается с резервуаром через канал 26. Пружинами 27,28 заслонка 3 удерживается в нейтральном положении. Между торцевыми поверхностями отрегулирован зазор, который может быть изменен путем ввинчивания или вывинчивания по резьбе 31. Технический эффект выражается в повышении надежности сервомеханизма в целом.The invention relates to hydraulic power. The servo valve contains control 1 and controlled 2 stages. In the control stage, a shutter 3 with protrusions 4,5 made on it is placed between the nozzles 6,7 and installed in the servo valve body on tapes 8,9, connected to the movable element of the electromechanical converter 10, with the frame 11 of the moving coil 12 located in the annular gap 13 The nozzles 6,7 are connected to the pressure source through the chokes 14,15 and channels 16,17,18,19, communicating with the end chambers 20,21 of the valve 22. The drain chamber 23 is sealed with membranes 24,25 and communicates with the reservoir through the channel 26. The 27.28 springs shutter 3 is held in a neutral cial position. A clearance is adjusted between the end surfaces, which can be changed by screwing or unscrewing the threads 31. The technical effect is expressed in increasing the reliability of the servo mechanism as a whole.
