Description

Изобретение относитс к устройствам дл коммутации пневматических каналов, может быть использовано в системах автоматического и дистанционного управлени .The invention relates to devices for switching pneumatic channels, can be used in automatic and remote control systems.

Известен электроплевматический преобразователь , содержащий элемент сравнени к штоку которого жестко прикреплен корь электромагнитного управлшощего элемента Xl .An electroplastic transducer is known, which contains an element for comparison with the rod of which the measles of the electromagnetic control element Xl are rigidly attached.

Наиболее близок к предлагаемому эле- ктропневматический преобразователь, содержащий установленную в корпусе мембрану с жестким центром из ферромагнитного материала, на котором закреплены заслон ки двух сопел, установленных в камерах корпуса, которые соединены между собой и выходным каналом; на соплах размещены обмотки управлени , подключенные ко входным каналам 2 .Closest to the proposed electro-pneumatic transducer, which contains a membrane with a rigid center made of ferromagnetic material installed in the housing, on which are mounted the dampers of two nozzles installed in the housing chambers, which are interconnected with the output channel; control nozzles are located on the nozzles connected to the input channels 2.

Самопроизвольное переключение пневматических каналов при исчезновении командного сигнала вследствие случайного временного отключени питани ограничи&ает функциональные возможности и сн№1кает эконо л1чность преобразователей.The spontaneous switching of the pneumatic channels with the disappearance of the command signal due to the accidental temporary disconnection of the power supply limits the functionality and reduces the efficiency of the converters.

Цель изобретени - расширение функциональных возможностей и снижение энергзатрат преобразовател .The purpose of the invention is to expand the functionality and reduce power consumption of the converter.

Поставленна цель достигаетс тем, что сопла преобразовател выполнены в виде посто нных магнитов с встречным размещением разноименных полюсов.The goal is achieved by the fact that the transducer nozzles are made in the form of permanent magnets with counter-placement of opposite poles.

На чертеже показана г1ринципиальна схема устройства.The drawing shows a schematic diagram of the device.

Камеры 1 и 2 корпуса со входными штуцерами 3, соединенными с соплами 4 пневмоконтактов, св заны между собой и с выходным каналом 5. На подвижной системе в виде мембраны 6 с жестким ценром из ферромагнитного материала зскреплены заслонки сопел 4. В корпусе закреплены электромагниты с обмотками управлени 7 и магнитопроводами В, часть которых о азована посто нными магнитами , вл ющимис соплами.The chambers 1 and 2 of the housing with the inlet nozzles 3 connected to the nozzles of 4 pneumatic contacts are connected to each other and to the output channel 5. On the moving system in the form of a membrane 6 with a rigid center made of ferromagnetic material, the nozzles 4 are fixed in the case. control 7 and magnetic circuit B, some of which are powered by permanent magnets, which are nozzles.

Claims

The device works as follows. In the case of short-term switching on a coil of electromagnets, a magnetic flux is created, the direction of which depends on the polarity of the applied voltage. During the interaction of magnetic fluxes generated by permanent magnets, which are part of the magnetic cores 8, and the windings 7 of the electromagnet, the resulting flux is amplified at one end of the magnetic circuit and weakened at the other. In this case, the mobile system moves in the direction of the enhanced magnetic flux and sticks to the permanent magnet. In this case, the flap overlaps one of the nozzles 4, providing switching of channel 5 with the second nozzle. After the removal of the input action, the mobile system remains in the occupied state. Installing it in another fixed state is provided by briefly applying: to the winding 7 of the electromagnet a current of opposite polarity. The use of an electropneumatic converter in the systems of remote switching of pneumatic channels allows creating reliable logic control systems with minimal sweat. Electricity reuse and multipurpose use of communication lines. Claims of the invention An electropneumatic transducer containing a membrane with a rigid center of ferromagnetic material installed in a housing, on which are mounted the dampers of two nozzles installed in the housing chambers that are connected to each other and the output channel on the nozzles are placed control windings connected to the input channels and - due to the fact that, in order to expand its functional capabilities and reduce power consumption, the nozzles are made in the form of permanent magnets: with counter-placement of unlike poles.
