Description
Известны задвижки дл трубопроводов с плоским шибером, соединенным со штоком привода и имеюш,им отверстие дл пропускани рабочей среды, где затвором служит сам шибер.Known valves for pipelines with a flat gate, connected to the actuator stem and having a hole for the passage of the working medium, where the gate itself is the gate.
Предлол енна задвижка отличаетс от известных тем, что в шибере установлен свободно перемеш,ающийс затвор, выполненный в виде диска, имеюш,его диаметр больший, чем диаметр нроходных отверстий в корпусе задвижки .An enlarged valve differs from the known ones in that the gate is fitted with a freely stirred valve, which is made in the form of a disk, having a diameter larger than the hole in the valve body.
На чертеже изображена описываема задвижка в разрезе.The drawing shows the described valve in the section.
В корпусе ) задвнжки перемеш,аетс шибер 2, соединенный со штоком 3 привода 4. В шибере установлен свободно неремеш,аюш,нйс диск-затвор 5j имеющ,ий диаметр больший, чем диаметр проходных патрубков а. В теле шибера выполнено отверстие б дл пропускани рабочей среды.In the housing of the rear wheel is mixed, the gate 2 is connected to the stem 3 of the actuator 4. The gate has a freely mounted, non-agitated, Ayush, gate valve 5j having a diameter larger than the diameter of the through-fittings a. A hole b is made in the body of the gate for the passage of the working medium.
При онуш,енном шибере затвор прижимаетс к седлу в корпусе давлением рабочей среды, обеспечива запирание задвижки.With onush valve, the valve is pressed against the seat in the housing by the pressure of the working medium, ensuring the locking of the valve.
При подн том шибере отверстие б совпадает с проходными патрубками а, обеспечива отпирание задвижки.When the gate is raised, the b hole coincides with the bore pipes a, ensuring that the valve is unlocked.
Предмет изобретени Subject invention
Задвижка дл трубопроводов, например, дл нневмо- и вакуум-транспорта, состо ща из корпуса, в котором перемещаетс шибер с отверстием дл прохода рабочей среды, отличающа с тем, что, с целью улучшени уплотн ющих свойств запорной пары, в шибере установлен свободно перемещающийс затвор, выполненный в виде диска, имеющего диаметр больший, чем диаметр проходных отверстий в корпусе задвижки.A valve for pipelines, for example, for non-vacuum and vacuum transport, consisting of a body in which a gate moves with an opening for the passage of the working medium, characterized in that, in order to improve the sealing properties of the locking pair, a freely moving valve is installed in the gate shutter, made in the form of a disc having a diameter larger than the diameter of the bore holes in the valve body.
