24 port rotary valve

Abstract

The invention discloses a 24-way rotary valve. The 24-way rotary valve is provided with a fixed disc; a rotary disc is arranged on the fixed disc; the fixed disc is provided with a plurality of concentrically annular grooves; the plurality of concentrically annular grooves which are mutually communicated with are communicated with the corresponding material pipes to form into a plurality of material channels; every channel is communicated with 24 valve position openings in the surface of the fixed disc and 24 valve position holes in the bottom of the fixed disc; the valve position holes are connected with corresponding technical pipes. The 24-way rotary valve also comprises material holes, material grooves which are formed in lower portions of the material holes and enable the surrounding of material holes to be mutually communicated, a shaft sleeve which sleeves the lower portion of a main spindle and inclined holes which are obliquely formed in the fixed disc; a surrounding of material holes are formed in the upper surface of the fixed disc; the bottom of the shaft sleeve is provided with a plurality of shaft sleeve holes; the shaft sleeve holes are communicated with the material grooves; upper ends of the inclined holes are connected with fan-shaped pipes on the exterior of the fan-shaped pipes; lower ends of the inclined holes are communicated with the material holes. According to the 24-way rotary valve, the grooves are not required to be formed again in the rotary valve, materials are directly conveyed through the center of the fixed disc, the space of the rotary disc is saved, and the material conveying efficiency is greatly improved.

Description

technical field [0001] The invention relates to a rotary valve, in particular to a 24-way rotary valve. Background technique [0002] In the prior art, the upper surface of the fixed plate of the rotary valve is covered with concentric annular grooves, and channels are provided at the bottom of each groove to pass through the fixed plate and communicate with the material pipe. On the periphery of the groove, there is a valve position port on the surface, the valve position hole at the bottom communicates with the process pipe, and there is a material cross-pipe on the turntable to form a channel that communicates with the valve position on the upper surface of the fixed plate. Each step is 1 time. A material span provides material for a unit of time. The surface of the fixed plate is full of grooves, and there is obviously no place to add another groove. It is too expensive and takes too long to make a new rotary valve. Contents of the invention [0003] The object of th...

Problems solved by technology

The surface of the fixed plate is full of grooves. I want to add another groove, but obviously there is no place. I have to make a new rotary valve. The price is too high and the time is too long
