Description
Известны шиберные задвижки с подвижными седлами, подпружиненными на шибер через уплотнительные прокладки.Known gate valves with movable seats, spring-loaded on the gate through the sealing gaskets.
Предложенна задвижка отличаетс от известных тем, что ее подвижные седла снабжены жестко укрепленными на них кулачками , взаимодействуюш,ими с копиром, св занным жестко со штоком подъема шибера. Шток укреплен с зазором, на величину которого движение копира опережает движение шибера. Это позвол ет улучшить услови работы задвижки.The proposed valve differs from the known ones in that its movable saddles are provided with cams rigidly fixed on them, interacting with the copier rigidly connected with the gate of the gate of the gate. The rod is strengthened with a gap, the magnitude of which the movement of the copier is ahead of the movement of the gate. This makes it possible to improve the operating conditions of the valve.
На штоке задвижки укреплены пальцы, действуюш,ие на обратный клапан при крайних положени х шибера.The fingers are fixed on the valve stem, acting on the non-return valve at the extreme positions of the gate.
На чертеже представлена задвижка в закрытом положении, разрез.The drawing shows the valve in the closed position, the cut.
В корпусе / задвижки размеш,ен шибер 2, в котором с зазором укреплен шток 3 с копиром 4, взаимодействуюш,им с кулачками подпружиненных седел 5 и пальцами 6 и 7, действующими на обратный клапан 8.In the housing / gate valves, there is a slide gate 2, in which the stem 3 is fixed with a gap 4 with a gap, it interacts with spring-loaded seats 5 and fingers 6 and 7 acting on the check valve 8 with them.
Дл открыти задвижки перемешаетс шток 3 подъема шибера 2, жестко св занного с копиром 4, раздвигающим седла 5. Среда подаетс в корпус Jl, разгружа шибер 2,To open the gate valve, the stem 3 is lifted by lifting the gate 2, which is rigidly connected to the cam 4, which is pushing the saddles 5. The medium is fed into the housing Jl, unloading the gate 2,
движение которого отстает от движени копира на величину зазора хода штока. В крайнем верхнем положении седла 5 съезл ают с копира 4, уплотн ют шибер, а давление из корпуса / сбрасываетс через обратный клапан 8, на который действует палец 6, укрепленный на штоке. Дл закрыти задвижки операции повтор ютс .the movement of which lags behind the movement of the copier by the amount of the clearance of the stroke of the rod. In the extreme upper position of the saddle 5, it is removed from the copier 4, the gate is compacted, and the pressure from the body / is released through a check valve 8, on which the pin 6, which is mounted on the rod, acts. To close the valve, the operations are repeated.
