Description
Известны задвижки дл вакуумных коммуникаций , в которых затвор выполнен в .виде гибкой стальной ленты, наматываемой на барабан . Уплотнение затвора осуществл етс поджатием ленты по периметру упругого седла подпружиненным металлическим кольцом.Known valves for vacuum communications, in which the shutter is made in the form of a flexible steel strip wound on a drum. The seal of the closure is carried out by pressing the tape around the perimeter of the elastic saddle with a spring-loaded metal ring.
Предложенна задвижка отличаетс от известных тем, что ,в ее проходном сечении установлено опорное решетчатое седло, на которое опираетс упругий ленточный затвор, при закрытом положении задвижки. Такое выполнение задвижки обеспечивает равномерную нагрузку затвора.The proposed valve differs from the known ones in that, in its flow section, there is a support lattice seat, on which the elastic band gate rests, in the closed position of the valve. This embodiment of the valve ensures uniform load of the shutter.
На чертеже схематически изображена задвижка дл вакуумных систем.The drawing shows schematically a valve for vacuum systems.
В корпусе / задвижки установлен барабан привода 2. Затвор 3 задвижки выполнен, например , в виде гибкой стальной ленты, наматываемой на барабан привода 2. В кольцевой канавке корпуса размещено упругое седло 4, например из резины или фтороплас. Проходное окно задвижки перекрыто опорной решеткой 5, к которой прижимаетс затвор 3, при закрытом положении задвижки.Drive drum 2 is installed in the housing / gate valve. Gate valve 3 is made, for example, in the form of a flexible steel tape wound onto the drive drum 2. In the annular groove of the body, an elastic seat 4, for example of rubber or fluoroplastic, is placed. The gate window of the valve is blocked by the support grille 5, against which the shutter 3 is pressed, in the closed position of the valve.
Затвор к седлу поджимаетс при помощи жесткого кольца 6 нал имными устройствами 7 в виде сильфонов, установленных в корпусе задвижки, по периметру седла 4.The closure to the saddle is tightened with the help of a rigid ring 6 with nalnyh devices 7 in the form of bellows installed in the valve body, along the perimeter of the saddle 4.
Предмет изобретени Subject invention
Задвижка дл вакуумных систем, состо ща из корпуса и затвора, выполненного, например , в виде -гибкой, стальной ленты, наматываемой на барабан привода, и лрижимаемого к уплотнительному кольцу седла при ломощи жесткого подпружиненного кольца, отличающа с тем, что, с целью обеспечени равномерной нагрузки затвора, в проходном сечении задвижки установлено решетчатое седло , на которое опираетс упругий ленточный затвор, при закрытом положении задвижки.A valve for vacuum systems consisting of a housing and a shutter, made, for example, in the form of a -flexible, steel tape, wound onto a drive drum, and pressed to the sealing ring of the saddle with a hard spring-loaded ring, characterized in that uniform load of the valve; in the bore section of the valve, there is a lattice saddle, on which the elastic belt valve rests, with the valve closed.
