Claims

[Claims for Utility Model Registration] A ceramic valve seat 1a is fixed to the base 16.
A plurality of pipes 5.6 connected to the valve seat 1a are connected to a plurality of vertical passages 18 at the periphery of the valve seat 1a, and a vertical passage 19 at the center of the valve seat 1a is connected to a processing tank connected to the base 16. A ceramic valve plate 1b is slidably stacked on the valve seat 1a, and has a passage 40 formed on the lower surface that communicates the vertical passage 19 in the center with one of the vertical passages 18 in the periphery. The lower plate 21 attached to the base 16 presses the spring 27 toward the valve plate 1b via the thrust bearing 28, and the circular convex portion 22 at the center of the valve plate 1b is radially moved by the hole at the center of the lower plate 21. The valve plate 1b is mounted on the upper plate 23 which bears a bearing and is fixed to the base 16.
A deceleration motor 24 is attached to drive the valve plate 1b, and a plurality of equally spaced slits 34 and a plurality of horizontally elongated openings 362 to 36d are provided in the control plate 31 attached to the valve plate 1b. matching and non-matching and valve plate 1b
A photoelectric detector 37a detects the rotational position of. A rotary valve for an embedding device provided with 37b and 38a to 38d.
