Description
Изобретение касаетс хранени легкоиспар ющихс жидкостей, в частности резервуаров , имеющих плавающую крышу и направл ющую стойку.The invention relates to the storage of highly evaporating liquids, in particular tanks having a floating roof and a guide post.
Известен герметизирующий затвор к плавающей крыше, включающий кольцевой диск, уплотн ющую прокладку и диафрагму 1.A sealing closure to a floating roof is known, which includes an annular disk, a sealing gasket and a diaphragm 1.
Известен также герметизирующий затвор , корпус которого выполнен в виде разъемной кольцевой обоймы, содержащей диски и диафрагму 2.Also known sealing shutter, the body of which is made in the form of a detachable ring holder containing the disks and the diaphragm 2.
Цель изобретени - повышение надежности эксплуатации нутем улучшени герметизации .The purpose of the invention is to increase the reliability of operation with the improved sealing.
Это достигаетс тем, что затвор дополнительно снабжен скобами из упругого материала и укрепленными на них прижимными роликами дл взаимодействи с поверхностью диска.This is achieved by the fact that the shutter is additionally provided with staples of elastic material and pressure rollers fixed on them to interact with the disk surface.
На фиг. 1 изображен предлагаемый герметизирующий затвор, поперечный разрез; на фиг. 2 - затвор при смещении плавающей крыши относительно направл ющей стойки, поперечный разрез.FIG. 1 shows the proposed sealing shutter, a cross-section; in fig. 2 - shutter at the displacement of the floating roof relative to the guide post, cross section.
Герметизирующий затвор состоит из трех упругих скоб 1, на концах верхнего плеча которых расположен прижимной ролик 2, укрепленный на вращающейс оси 3, кольцевого диска 4 с диафрагмой 5, контактирующей с направл ющей стойкой 6 плавающей крыщи 7. Нижнее плечо скобы прикреплено к патрубку с помощью болтов 8.The sealing bolt consists of three elastic brackets 1, at the ends of the upper arm there is a pressure roller 2 fixed on the rotating axis 3, an annular disk 4 with a diaphragm 5 in contact with the guide post 6 of the floating roof 7. The lower arm of the bracket is attached to the nipple using bolts 8.
Затвор работает следующим образом.The shutter works as follows.
При движении плавающей крыши 7 диафрагма 5 скользит по направл ющей стойке 6, сохран контакт с ней. Упругие скобы 1 через прижимные ролики 2 прижимают кольцевой диск 4 к уплотнительной поверхности 9 патрубка 10, герметизиру пространство под диском. При смещении плавающей крыши 7 относительно стойки 6 уплотнительна поверхность 9 патрубка 10 перемещаетс относительно кольцевого диска 4. При этом прижимной ролик 2 катитс по поверхности диска.When the floating roof 7 moves, the diaphragm 5 slides along the guide post 6, maintaining contact with it. Elastic brackets 1 through the pinch rollers 2 press the annular disk 4 to the sealing surface 9 of the nozzle 10, sealing the space under the disk. When the floating roof 7 is displaced relative to the post 6, the sealing surface 9 of the nozzle 10 moves relative to the annular disk 4. At the same time, the pressure roller 2 rolls along the surface of the disk.
Преимуществом данного герметизирующего затвора также вл етс простота обслуживани и ремонта.The advantage of this sealing gate is also ease of maintenance and repair.
