CONTACT ELEMENT OF VALVE DISC AND METHOD TO INSTALL CONTACT ELEMENT Russian patent published in 2012 - IPC B01D3/22 B01D3/30 B01D53/18 

FIELD: instrument making.

SUBSTANCE: invention relates to designs of contact devices for rectification and absorption devices. The contact element of the valve disc comprises a valve with two vertically directed legs equipped with lifting limiters. Lifting limiters are arranged in the form of symmetric tabs. In the area of connection of tabs with legs, in angles of bend, the cross connection of tabs and legs is reduced by 1/4 of their width, and the length of tabs L in the unfolded form makes (0.7÷0.8)·D, where D is the diametre or width of a hole on the disc plane. Tabs of legs are bent in a horizontal plane at the angle of 110-120° between tabs. At the same time at one of the legs the tabs are bent towards the centre of the valve, and on the other one - away from the centre. The method to install a contact element includes insertion of the contact element into the hole of the disc plane. After insertion of the tab into the hole of the disc plane those legs that are bent towards the valve centre are bent in the horizontal plane in direction from the centre with the angle of 110-120° between tabs. The height of the valve lift is controlled with the leg length by bending tabs in the vertical plane by the angle of up to 90°.

EFFECT: reduced labour intensiveness and improved quality of contact element installation into the disc plane with provision of its stable operation.
