Description

Изобретение касаетс  вентил торостроени .This invention relates to a toroid valve.

Известны вентил торы дл  перекачивани  взрывоопасных сред, содержащие корпус и расположенное в нем рабочее колесо, выполненные из материалов, исключающих искрообразование , например из пластмассы. Рабочее колесо установлено на валу приводного электродвигател .Ventilators for pumping explosive atmospheres are known, comprising a housing and an impeller located therein, made of sparking materials such as plastics. The impeller is mounted on the drive motor shaft.

Описываемый вентил тор отличаетс  от известных тем, что, внутренние .полости вентил тора и электродвигател  соединены кольцевым зазором до 0,3 мм, выполненным между корпусом и валом, на длине до 25 мм.The fan described here differs from those known in that the internal cavities of the fan and the electric motor are connected by an annular gap of up to 0.3 mm between the case and the shaft, up to 25 mm in length.

Это позвол ет использовать дл  привода взрывонезащищенный электродвигатель.This makes it possible to use an explosion-proof motor for the drive.

На чертеже схем атично изображен описываемый вентил тор.The schematic drawing shows the fan described in detail.

В корпусе /, изготовленном из материалов, исключающих искрообразование, находитс  рабочее колесо 2, насаженное непосредственно на вал 3 взрывонезащищенного электродвигател , и втулка 5, образующа  с наружной ловерхностью ступицы 6 рабочего колеса кольцевой зазор а. Зазор а соедин ет по валу электридвигател  через уплотнение 7 внутреннюю полость вентил тора с внутренней -ПОЛОСТЬЮ электродвигател .In the case / made of materials that exclude sparking, there is an impeller 2 mounted directly onto the shaft 3 of an explosion-proof electric motor, and a sleeve 5 forming an annular gap with the outer surface of the impeller hub 6. The gap a connects the shaft of the electric motor through the seal 7 to the internal cavity of the fan with the internal cavity of the electric motor.

К электровентил тору подсоедин ют трубопроводы , соедин ющие его с помещением, из которого необходимо откачивать взрывоопасную среду, и с пространством, в которое перекачивают эту среду. Электровентил тор быть установлен в помещении, не содержащем взрывоопасных сред. В случае взрыва в электродвигателе взрывна  волна проходит по зазору между валом и корпусомPipelines are connected to the fan assembly connecting it to the room from which the explosive atmosphere must be pumped, and to the space into which this medium is being pumped. Electric fan to be installed in a room that does not contain explosive atmospheres. In the event of an explosion in an electric motor, an explosive wave travels through the gap between the shaft and the housing.

электродвигател  через уплотнение и, попада  в зазор между корпусом вентил тора и валом электродвигател , гаситс  в нем, не распростран  сь на перекачиваемую среду.the motor through the seal and, falling into the gap between the fan casing and the motor shaft, is quenched in it, not spreading on the pumped medium.
