Description
Задвижка илИ клаиаи привод тс li движение иггоком -1 (фиг. :П двухполостного иоршневого привода, заключенного и корпус 2. Привод питаетс маслом, нагнетаемым шестеренчатым пасосом 3, который вращаетс реверсивным электродвигателем 4. Насос нерекачивает масло ИР, нолостн А привода в иолость Б или обратно по маслоироводам 5 и 6.The valve or valve is driven by the movement of an Iggoc -1 (Fig.: A two-cavity actuator, a prisoner and a casing 2. The actuator is fed with oil, pumped by gear pasos 3, which is rotated by a reversing electric motor 4. The pump doesn’t pump the oil I, but the actuator B and B or back on the oil masks 5 and 6.
В крайних ноложени х норнш 7 электродвигатель 4 отключаетс концевыми выключател ми 8, которые привод тс в действие новодком 9. При избыточном давлении на шток 1 в полост х А или Б нривода иредохранительиыс клананьг 10 и И открываютс и пронускают масло из полости 12 в сливной резервуар 13 по трубке 14. Во врем срабатывани клаианов 10 и 11 они воздействуют на блок-контакты 15 п 16, которые отключают электродвигатель. Клапан 11 открываетс дл выпуска масла, вытесн емого штоком Н1)и движениг норган 7 вверх, который регулируетс так, чтобы тгри птом блок-контакт 16 не срабатывал .In extreme positions, the 7th motor 4 is turned off by limit switches 8, which are actuated by the pump 9. When the rod 1 in the cavities A or B of the actuator has an excessive pressure, the fuse 10 and And open and pass the oil from the cavity 12 to the drain tank 13 in handset 14. During operation of the clauses 10 and 11, they act on the auxiliary contacts 15 and 16, which turn off the electric motor. The valve 11 is opened to release the oil displaced by the stem H1) and the movement of the norgan 7 upwards, which is adjusted so that the crimping contact 16 does not work.
При движении поршн вниз открываетс обратный клапан 17, пропускающий масло в нолость Б через иолость 18 и трубку 19. Основное же назначение обратных клапанов 17 и 20- компенсаци утечкп масла из полостей новыптепного давлени .When the piston moves downwards, a non-return valve 17 opens, allowing oil to flow into the cavity B through the cavity 18 and pipe 19. The main purpose of the non-return valves 17 and 20 is to compensate for the leakage of oil from the cavities of the new pressure.
