Description
ный распределитель 9 подаетс в одну из насадок 11 (на фиг. 3 - правую). По окончании гидравлического удара напорный клапан 7 закрываетс , а ударный клапан 5 открываетс . В конце хода открыти клапана 5 его шток 6, воздейству на переключатель 10, с помощью электромагнитов 12 переводит распределитель 9 из одного крайнего положени в другое (в данном случае - правое), при этом подготавливаетс к работе лева насадка 11.A distributor 9 is fed to one of the nozzles 11 (in FIG. 3, the right one). At the end of the water hammer, the pressure valve 7 closes and the shock valve 5 opens. At the end of the opening stroke of the valve 5, its rod 6, acting on the switch 10, by means of electromagnets 12, transfers the distributor 9 from one extreme position to another (in this case the right one), while the left nozzle 11 is prepared for operation.
При определенной скорости (ниже допустимой ) движени рабочей жидкости в напорной магистрали 3 напорный клапан 7 закрыт, вследствие чего не происходит истечение жидкости из насадок 11. При возникновении следующего гидравлического удара клапан 5 закрываетс , при этом электрическа схема не переключаетс , так как переключатель 10 снабжен фиксатором (на чертеже не показано ) и поэтому срабатывает при повторном воздействии штока 6; напорный клапан 7 открываетс , происходит впрыск через левую насадку 11. После окончани гидравлического удара клапан 5 вновь открываетс и в конце хода открыти , воздейству на переключатель 10, с помощью электромагнитов 12 переводитAt a certain speed (below the allowable) movement of the working fluid in the pressure line 3, the pressure valve 7 is closed, as a result of which there is no outflow of fluid from the nozzles 11. When the next water hammer occurs, the valve 5 closes and the electrical circuit does not switch because switch 10 is provided the latch (not shown) and therefore triggered by repeated exposure to the rod 6; the pressure valve 7 opens, the injection takes place through the left nozzle 11. After the end of the water hammer, the valve 5 opens again and opens the switch at the end of the stroke, acts on the switch 10, translates by electromagnets 12
распределитель 9 в левое положение. Таким образом обеспечиваетс поочередный впрыск рабочей жидкости в два р да за один проход агрегата.valve 9 to the left position. In this way, alternate injection of the working fluid in two rows in a single pass of the unit is ensured.
