Изобретение относитс к арматуростроспию .The invention relates to reinforcement.

Известен кл-аиан с электромагнитным приводом, содержащий корпус, в. котором установлен запорный орган, соединенный с сердечником электромагнита , нагруженным пружиной 1 .Known CL-AIAN with an electromagnetic drive, comprising a housing, in. which has a locking organ connected to the core of the electromagnet, loaded with spring 1.

Недостатком известного устройства вл етс неравномерный износ уп-лотнительного элемента из-за неравномерного распределени уплотн ющего усили по периметру уплотнительного элемента, что снижает надежность клапана.A disadvantage of the known device is the uneven wear of the sealing element due to the uneven distribution of the sealing force around the perimeter of the sealing element, which reduces the reliability of the valve.

Известен вакуумный клапан, содержащий установленный в корпусе полый запрр1а |й орган, в полости которого размещен нагруженный упругим элементом шток, св занный с корем элект .ромагнита 2.A vacuum valve is known, which comprises a hollow valve installed in the housing, in which a cavity is loaded with a rod loaded with an elastic element and connected to the core of the electromagnet 2.

Недостатком известного устройства вл етс снижение герметичности, а также увеличение зазора между штоком и запорным органом, так как этиA disadvantage of the known device is a decrease in leak tightness, as well as an increase in the gap between the rod and the locking member, since these

детали взаимодействуют с ударом, что снижает надежность клапана.parts interact with the blow, which reduces the reliability of the valve.

Цель изобретени - повыше1ше надежности клапана.The purpose of the invention is higher valve reliability.

Поставленна цель достигаетс тем, что запорный орган выполнен из двух частей, размещенных одна в другой с возможностью взаимного перемещени , а упругий элемент размещен между торцами штока и внутренней части запорного органа, причем клапан снабжен дополнительной пружиной, уст новленной между корпусом и наружной частью запорного органа со стороны кор электромагнита.The goal is achieved by the fact that the locking member is made of two parts placed one inside the other with the possibility of mutual movement, and the elastic element is placed between the ends of the stem and the inner part of the locking member, and the valve is provided with an additional spring installed between the body and the outer part of the locking member from the core of the electromagnet.

На чертеже показан вакуумный клапан , разрез.The drawing shows a vacuum valve section.

Claims

The body 1 is equipped with a zaporn1 organ consisting of the outer part 2 and the inner part 3 installed with the possibility of reciprocal movement. In the cavity of the outer part 3, a rod 4 is installed, connected to the core 5 of the electromagnet 6. A resilient element 7 is placed between the ends of the rod 4 and the inner part 3, and an additional spring 8 is installed between the case I and the outer part 2 of the locking organ. By applying voltage to the electromagnet 6, the bore 5 is drawn in through the outer part 2 of the valve, compressing the spring 8, moves the inner part 3 of the valve, and the elastic element 7 eliminates the possibility of the impact of the rod 4 and the outer part 2. Punching the bark 5 is returned by the spring 8 to its original position, while the elastic element 7 prevents the rod and the inner part 3 of the blocking body from colliding. The spring force of the spring 8 acts on the center of the inner part 3 through the elastic element 7, which deforms, releasing the inner part 3, the latter being self-aligning with the seat of the housing 1. The proposed valve has a higher reliability, because the sealing force applied in the center of the inner part 3 is distributed evenly around the perimeter. The exception in the possibility of the impact of the end of the stem and the outer part of the closure member allows reducing wear and increasing the reliability and durability of work. Claims of the invention A vacuum valve comprising a hollow closure member installed in the housing, in the cavity of which a rod loaded with an elastic element is connected to the electromagnet core, characterized in that, in order to increase reliability, the closure body B1 is made of two parts placed one inside the other. can be reciprocally moved, and the elastic element is placed between the ends of the stem and the inside of the closure member, the valve being provided with an additional spring installed between the housing and the outside part of the closure organ from the core of the electromagnet.
