Refractory disc set for three-disc closure

专利摘要:
The invention relates to foundry, in particular, to closures for discharging molten metal from a metallurgical vessel. The purpose of the invention is to increase the life of the kit. The valve kit consists of fixed inlet 1 and outlet 5 discs, a movable locking disc 3 in which channels 2. 6 and 4 are made, respectively. In the upper part of the drain channel 6 conical expansion 9 is made, and the axes of channels 2 and 6 are offset by the value of X. 4 Cp. f-ly, 8 ill.

Claims (5)
[1]
1. Flameproof disc set for disk valves, preferably for adjusting the melt feed during continuous casting, containing the inlet and
exhaust fixed discs with drain channels and locking movable disc with a through-passage, located between the fixed discs, the discharge channel of the exhaust disc is made with an extension to
the direction of locking the movable disk, characterized in that, in order to increase the service life of the kit, the axis of the discharge channel of the exhaust disk is offset relative to the axis of the drain channel, the inlet disk in the direction of closing the locking disk, and the expansion of the drain channel of the exhaust disk is made conical in its upper part.
[2]
2. The kit according to claim 1, characterized in that the displacement of the axes of the drain channels is 0.1-0.5 of the diameter of the drain channel of the intake disc.
[3]
3. The kit according to claim 1, characterized in that the conical expansion is performed on opposite sides of the discharge channel in the direction of movement of the movable disk.
[4]
4. Set of paragraphs. 1 and 3, characterized in that the width of the conical extensions. at least equal to the magnitude of the axial displacement.
[5]
5. Set of PP. 1 and 2, characterized in that the diameter of the drain channel of the intake disc is smaller than the diameter of the drain
the channel of the intake disk by an amount equal to two axial displacements m.
