Description
Система управления устройством регулирования потока вещества Substance flow control device control system
Изобретение относится к промышленным системам автоматического регулирования, обеспечивающим функционирование сложных процессов, в частности, химических процессов, где осуществляют регулирование потока вещества. Изобретение может быть применено с целью повышения удобства управления запорной арматурой и другими подобными логическими элементами на ее основе, например, для автономной работы устройств таких систем, как умный дом, производственные машины для обработки деталей и материалов и т.п. The invention relates to industrial automatic control systems that ensure the functioning of complex processes, in particular, chemical processes, where the flow of matter is regulated. The invention can be applied to improve the convenience of control of valves and other similar logical elements based on it, for example, for autonomous operation of devices of such systems as a smart home, production machines for processing parts and materials, etc.
Известны аналогичные системы управления устройством регулирования потока вещества, среди которых ближайшими являются системы, где применяют соленоиды прямого действия (электромагнитные клапаны), например, описанные в https://www.ita az.com.ua/ua/wiki/solenoid- valve.html. Такие системы содержат расположенные в корпусе электромагнитную катушку (соленоид) и сердечник, расположенный внутри катушки. Сердечник является подвижным запорным элементом, расположенным с возможностью возвратно-поступательного движения вдоль своей оси при подаче управляющего электрического сигнала на электромагнитную катушку. Как правило, электромагнитная катушка работает под рабочим напряжением 12-220 Вольт при относительно большой мощности, что требует подключения системы к сети электропитания или к питанию от аккумуляторов большой емкости и габаритов и поэтому приводит к ограничению применения из-за недостаточной автономность таких систем. Known similar control systems for the device for regulating the flow of matter, among which the closest are systems where solenoids of direct action (electromagnetic valves) are used, for example, described in https: //www.ita az.com.ua/ua/wiki/solenoid-valve. html. Such systems contain an electromagnetic coil (solenoid) located in the housing and a core located inside the coil. The core is a movable shut-off element located with the possibility of reciprocating movement along its axis when a control electrical signal is applied to the electromagnetic coil. As a rule, an electromagnetic coil operates under an operating voltage of 12-220 Volts at a relatively high power, which requires the system to be connected to a power supply network or powered by batteries of large capacity and dimensions and therefore leads to a limitation of use due to insufficient autonomy of such systems.
В основу изобретения поставлена задача создания упрощенной системы управления устройством регулирования потока вещества, которая позволяет уменьшить рабочее напряжение и электрическую мощность, необходимые
для управления и осуществления автономного управления, и которая не требует подключения к сети электропитания или применения крупногабаритных аккумуляторов. The basis of the invention is the task of creating a simplified control system for a device for regulating the flow of a substance, which makes it possible to reduce the operating voltage and electrical power required for control and implementation of autonomous control, and which does not require connection to the power supply network or the use of large-size batteries.
Для решения поставленной задачи предложена альтернативная система управления устройством регулирования потока вещества, содержащим подвижный запорный элемент, расположенный с возможностью возвратно- поступательного движения вдоль своей оси, которая, согласно изобретению, дополнительно содержит постоянный магнит, расположенный коаксиально подвижному запорному элементу с возможностью движения вместе с ним, и позиционер, управляемый электрическим сигналом, причем подвижный запорный элемент приводится в движение позиционером, имеющим степень свободы, коллинеарную вектору линейного перемещения постоянного магнита для возвратно-поступательного движения подвижного запорного элемента. To solve this problem, an alternative control system is proposed for a device for regulating the flow of a substance, which contains a movable closure element located with the possibility of reciprocating movement along its axis, which, according to the invention, additionally contains a permanent magnet located coaxially with the movable closure element with the possibility of movement with it and a positioner controlled by an electrical signal, the movable closure being driven by a positioner having a degree of freedom collinear with the linear vector of the permanent magnet for reciprocating the movable closure.
В такой системе, которая альтернативна соленоидной системе, соленоид и устройство, которое обеспечивает управляющий электрический сигнал последнему, заменены подвижным постоянным магнитом, коаксиальным подвижному запорному элементу (подвижному сердечнику соленоида, как в прототипе). Такой подвижный сердечник приводится в движение позиционером, который имеет степень свободы, коллинеарную вектору линейного перемещения постоянного магнита в соответствии с законами электромагнитного поля, что придает возвратно-поступательное движение подвижному сердечнику и обеспечивает алгоритм работы, по сути, аналогичный известной соленоидной системе. Однако, в отличие от соленоидной системы, в результате замены соленоида, который работает, как правило, от напряжения 12-220 Вольт, на позиционер, который имеет меньшую мощность и меньшее рабочее напряжение (3-5 Вольт), появляется
возможность применения малогабаритных аккумуляторов небольшой емкости, которые обеспечивают работу системы, автономную от сети. In such a system, which is an alternative to the solenoid system, the solenoid and the device that provides a control electrical signal to the latter are replaced by a movable permanent magnet coaxial with a movable closure element (movable solenoid core, as in the prototype). Such a movable core is set in motion by a positioner, which has a degree of freedom collinear with the linear vector of the permanent magnet in accordance with the laws of the electromagnetic field, which imparts a reciprocating motion to the movable core and provides an operation algorithm essentially similar to the known solenoid system. However, unlike the solenoid system, as a result of replacing the solenoid, which usually operates from a voltage of 12-220 Volts, with a positioner, which has less power and a lower operating voltage (3-5 Volts), appears the possibility of using small-sized batteries of small capacity, which ensure the operation of the system, autonomous from the network.
Согласно одному из предпочтительных вариантов выполнения системы, как позиционер может быть использован пневматический привод или гидравлический привод или механический привод или ручной привод или их комбинация, которые приспособлены обеспечить перемещение постоянного магнита и выполнения алгоритма работы, аналогичного соленоидной системе. Выбор типа привода зависит от требований, которым должна соответствовать система. According to one of the preferred embodiments of the system, a pneumatic actuator or a hydraulic actuator, or a mechanical actuator or a manual actuator, or a combination thereof, can be used as a positioner, which are adapted to move a permanent magnet and perform an operation algorithm similar to a solenoid system. The choice of the type of drive depends on the requirements to be met by the system.

Клапан для реализации системы управления устройством регулирования потока вещества создан на основе стандартного электромеханического клапана, например, производства компанииThe valve for the implementation of the control system of the device for regulating the flow of a substance is created on the basis of a standard electromechanical valve, for example, manufactured by the company
Camozzi, http://catalog.camozzi.ua/, в котором отсутствует электромагнитная катушка (соленоид), которая приводит сердечник в возвратно- поступательное движение, что обеспечивает управление потоком воды. Вместо электромагнитной катушки система клапана содержит кольцевой магнит 6, прикрепленный стопорным кольцом 13 к движку 3. Движок 3 имеет вертикальную степень свободы вдоль штока клапана, который выполняет роль подвижного запорного элемента и входит в состав гидрораспределителя 4 как сердечник, а также дополнительную направляющую в виде штифта 12. Движок 3 выполнен как ходовая втулка -
конструктивный элемент, необходимый для того, чтобы магнит 6 имел возможность свободного перемещения и тем самым мог перемещать подвижной запорный элемент клапана. Движок 3 также обеспечивает ручное управление работой клапана. Движок 3 с магнитом 6 приводится в движение электромеханическим приводом 5 (рычажным электромеханическим мотор-редуктором), который выполняет роль позиционера и таким образом перемещает сердечник (подвижный запорный элемент), обеспечивая функционирование клапана для регулирования потока воды. Система дополнительно может содержать блок управления (на чертеже не показан), выполненный для передачи управляющего электрического сигнала позиционеру. Блок управления одновременно может быть и аккумулятором. Camozzi, http://catalog.camozzi.ua/, in which there is no electromagnetic coil (solenoid), which drives the core in a reciprocating motion, which provides control of the water flow. Instead of an electromagnetic coil, the valve system contains an annular magnet 6, attached by a retaining ring 13 to the slider 3. The slider 3 has a vertical degree of freedom along the valve stem, which acts as a movable locking element and is part of the valve 4 as a core, as well as an additional guide in the form of a pin 12. Engine 3 is designed as a travel sleeve - a structural element necessary for the magnet 6 to be able to move freely and thus be able to move the movable closure of the valve. Slider 3 also provides manual control of the valve operation. The motor 3 with the magnet 6 is driven by an electromechanical drive 5 (lever electromechanical gear motor), which acts as a positioner and thus moves the core (movable closure element), ensuring the functioning of the valve to regulate the water flow. The system may additionally comprise a control unit (not shown in the drawing) configured to transmit an electrical control signal to the positioner. The control unit can also be a battery at the same time.
Промышленная применимость. Конструкция системы управления устройством регулирования потока вещества, например, в виде описанного выше клапана управлением водой может быть выполнена из стандартных и известных элементов, которые применяются в подобной отрасли, в частности, и для электромагнитных клапанов. Например, корпус 1 , основание 2 и позиционер 3 могут быть выполнены из пластика, стойка 9, гайка 10, планка 11 и штифт 12 могут быть стальными, а магнит 6 выполнен из сплава железо-никель-алюминиевой основе (AlNiCo, альнико) или на основе сплава неодима, бора и железа (неодимовый магнит) или другого подобного. Industrial applicability. The design of the control system of the device for regulating the flow of a substance, for example, in the form of the above-described water control valve, can be made of standard and known elements that are used in a similar industry, in particular, for solenoid valves. For example, body 1, base 2 and positioner 3 can be made of plastic, post 9, nut 10, bar 11 and pin 12 can be steel, and magnet 6 is made of iron-nickel-aluminum alloy (AlNiCo, alnico) or on based on an alloy of neodymium, boron and iron (neodymium magnet) or the like.
Таким образом, изобретение обеспечивает альтернативную упрощенную систему управления устройством регулирования потока вещества, приводит к уменьшению рабочего напряжения и электрической мощности, необходимых для управления, и к осуществлению автономного управления, а также не требует подключения к сети электропитания или применения крупногабаритных аккумуляторов.
