(54) УСТРОЙСТВО ДЛЯ АВТОМАТИЧЕСКОГО ВЫПУСКА(54) DEVICE FOR AUTOMATIC ISSUE

1one

Изобретение относитс к арматуростроению , преимущественно к пневмо-гидроавтоматике .The invention relates to valves, mainly to pneumatic hydraulics.

Известно устройство дл автоматического удалени воздуха, запорный орган .которого .выполнен в виде поплавка, св - занного посредством коромысла с клапаном , наход щимс под давлением скапливающегос над жидкостью воздуха 1.A device is known for the automatic removal of air, the locking member of which is made in the form of a float, which is connected by means of a rocker arm to a valve, which is under the pressure of air accumulating above the liquid 1.

Недостатком такого устройства вл етс низка надежность из-за наличи больщого количества взаимодействующих ю элементов.The disadvantage of such a device is low reliability due to the presence of a large number of interacting elements.

Наиболее -близким по технической сущности вл етс устройство, корпус которого разделен на две камеры, в одной из которых установлен электрод, а в другой, 5 имеющей воздуховыпускные отверсти , смонтирован клапан с соленоидным приводом 2.The closest in technical essence is a device, the casing of which is divided into two chambers, in one of which an electrode is installed, and in the other, 5 having air outlets, a valve with solenoid actuator 2 is mounted.

Недостатком данного устройства вл етс его низка надежность из-за пол ризации электродов.The disadvantage of this device is its low reliability due to polarization of the electrodes.

Цель изобретени - повыщение надежности устройства.The purpose of the invention is to increase the reliability of the device.

ВОЗДУХАAIR

Это достигаетс тем, что в известном устройстве, содержащем корпус с выпускными отверсти ми, в котором расположен клапан, управл емый соленоидным приводом , приводимым в движение при срабатывании чувствительного элемента, в нижней части полости Kopriyca неподвижно закреплен посто нный магнит над которым размещен поплавок с укрепленным в его нижней части посто нным магнитом, обращенным одноименным полюсом к неподвижному посто нному магниту, а чувствительный элемент выполнен в виде геркона и размещен между поплавком и неподвижным магнитом.This is achieved by the fact that in a known device comprising a housing with outlets, in which a valve is located, controlled by a solenoid actuator, which is set in motion when the sensor element is activated, a permanent magnet is fixed in the lower part of the Kopriyca cavity. in its lower part by a permanent magnet, turned by the same pole to a stationary permanent magnet, and the sensitive element is designed as a reed switch and is placed between the float and the stationary magnet itom.

На чертеже показано описываемое устройство .The drawing shows the described device.

Claims

The device consists of a housing 1 made of a non-magnetic material, in the upper part of which a valve 2 is located, air outlets 3 and a solenoid actuator 4. In the lower part of the housing 1 there is a throttle washer 5 on which a permanent lower magnet 6 is rigidly attached. Second magnet 7 mounted on the float 8, the magnets 6 and 7 are facing each other like poles, between which is placed the reed switch 9, enclosed in a capsule of a nonmagnetic material 10. The device works as follows. In the absence of air in the system, the internal cavity of the housing 1 is filled with liquid, the float 8 with the magnet 7 is in the upper position, the contacts of the reed switch 9 de-energize the solenoid actuator 4 and the valve 2 is closed. When air enters the cavity of the housing 1, the liquid is displaced and the float 8 is lowered. In this case, the magnetic field strength changes, as a result of which the reed switch 9 turns on the solenoid actuator 4, the valve 2 opens, the air is released through the openings 3. The use of this device will make the removal of air from the systems more efficient with minimal accumulation. Claims of the Invention A device for automatic venting, in a housing of which there is a valve with outlets, which is controlled by a solenoidal actuator that is set in motion when the sensitive element is activated, characterized in that, in order to increase the reliability of the device, in the lower part of the cavity of the housing This magnet, over which is placed a float with a permanent magnet fixed in its lower part, turned by one nominal pole to a stationary permanent magnet, and th element is a reed switch and is arranged between the float and the stationary magnet.
