Rotary gas distribution valve

Abstract

The invention relates to a rotary gas distribution valve which comprises a valve shell, a valve core and a motor, and is characterized in that the valve core comprises an upper disk, a middle disk and a lower disk; the upper surface of the middle disk is connected with a small disk; a first connecting block is arranged between the upper disk and the small disk; and the first connecting block comprises two sector blocks with the cross sections being in sector shapes. The upper end and the lower end of the first connecting block are respectively connected with the upper disk and the small disk. A half disk is connected onto the small disk. An axial hole is arranged in the center of the half disk, the axial hole extends downwards and is communicated with the spacing between the middle disk and the lower disk. The valve shell is in a cylindrical shape, and the outer circles of the upper disk, the middle disk and the lower disk are movably matched with the valve shell. A large gear ring is arranged on the upper disk. The axial hole is arranged in the center of the large gear ring, a radial hole is arranged on the outer circle of one sector bock in the first connecting block, and the radial hole is communicated with the axial hole on the large gear ring. A small gear ring is arranged on the outer shaft of the motor, and the small gear ring is meshed with the large gear ring. The rotary gas distribution valve is good in reliability and low in maintenance cost, and is applicable to a multi-compartment heat storage burning device.

Description

technical field [0001] The present invention relates to a gas distributing valve (device), in particular, it can make two or more kinds of gases (exhaust gas, purified gas, air) flow in the same distributing valve (device) from one inlet pipe regularly. Distributed to one or more pipelines or compartments, after purification, they are collected from one or more pipelines or compartments and discharged into one pipeline, and can be introduced from the exhaust gas or external air. A gas distribution valve in which a stream of gas enters more than one pipe or compartment. It can be widely used in two-compartment or multi-compartment (above three-compartment) compartment regenerative incineration device, two-compartment or multi-compartment (above three-compartment) compartment regenerative catalytic oxidation device, two-compartment or multi-compartment (above three-compartment) compartment Activated carbon, zeolite, activated carbon fiber adsorption and desorption gas purificat...

AI Technical Summary

Problems solved by technology

Due to the complexity of these process actions, it is necessary to preset programs in the controller to control multiple valve actuators, making the reliability poor

And because multiple valves, valve actuators, and PLC control systems are required, not only the equipment investment is large, but also the repair and maintenance costs are high
