Известны ограничители расхода жидкости пр мого действи , подвижный плунжер которых перемещаетс под действием статического и динамического напоров. Так1ие ограничители не могут работать на загр зненной среде.Limiters for direct flow of fluid are known, the movable plunger of which moves under the action of static and dynamic pressure. These limiters cannot operate on a polluted environment.
Предложенный ограничитель расхода пр мого действи позвол ет устранить этот недостаток . С этой целью вводитс заслонка, воспринимающа действие статического и динамического напоров потока и св занна через рычаг с плунжером.The proposed direct flow restrictor eliminates this disadvantage. For this purpose, a damper is introduced, perceiving the action of static and dynamic head of the flow and connected through a lever with a plunger.
На чертеже схематически представлен описываемый ограничитель.The drawing schematically shows the described limiter.
Он состоит из корпуса /, входного и выходного патрубков 2, 3, седел 4, плунжера 5, пружины 6, заслонки 7, рычага 8, оои 9 и груза 10.It consists of a housing /, inlet and outlet pipes 2, 3, seats 4, plunger 5, spring 6, valve 7, lever 8, ooi 9 and load 10.
При нормальном расходе плунжер 5 находитс в крайнем нижнем положении вследствие превыщени момента на оси 9 от груза иAt normal consumption, the plunger 5 is in its lowest position due to the excess of torque on the axis 9 from the load and
пружин над моментом от действи гидродинамических сил на заслонку 7.springs above the moment from the action of hydrodynamic forces on the valve 7.
При превыщении расхода выше нормы усили на заслонку создают превышение момента над моментом от пружины и груза, и плунжер 5 перекрывает проходные отверсти .When the flow exceeds the norm, the force on the valve creates an excess of torque over the moment from the spring and the load, and the plunger 5 blocks the bore holes.
Предмет изобретени Subject invention
Ограничитель расхода пр мого действи , содержащий корпус и подвижный плунжер, перемещающийс от действи на него динамического и статического напоров движущейс среды, отличающийс тем, что, с целью повышени надежности при работе на загр зненной среде, действие на плунжер динамического и статического напоров осуществлено через заслонку, установленную в потоке и механически св занную с плунжером, например, через рычаг, при этом подвижный плунжер выполнен стержневым.A direct flow restrictor, comprising a housing and a movable plunger moving from a dynamic and static head against a moving medium, characterized in that, in order to increase reliability when operating on a contaminated medium, the dynamic and static head is applied to the plunger mounted in the flow and mechanically connected to the plunger, for example, through a lever, wherein the movable plunger is rod-shaped.
