SU55102A1 - Valve for switching air regenerators - Google Patents

Description

The basic requirements that reversible devices (in particular, for air) used in furnace installations must meet are the simplicity of the design, the sufficient tightness and the least possible resistance that it must exert to the passage of gases.

Of the existing designs of air valves, the valves of the spherical type have a number of significant advantages over the valves of other systems (moth, slide valves, etc.), but at the same time, conventional valves of the gate type have a number of disadvantages, such as: lack of simplicity and compactness and necessity successive rotations of the flue gases by S0 ° in different directions, as is the case in some of them, which is associated with losses of thrust force.

In order to eliminate the aforementioned deficiencies in the proposed valve for switching air regenerators with the help of two mutually interconnected mutually coupled dampers in opposite directions, the latter are located in the same plane

in two parallel hogs converging behind the slides into a common smoke hog. Parallel hogs are provided in their canals and in the vaults with windows covered with a common box. The box is divided by a partition with windows through which, by alternately moving the gates, air is admitted into the hog.

FIG. 1 is a front view of a valve for switching air regenerators; FIG. 2- side view of it in section; FIG. 3 is a top view of it in section.

The valve consists of two gates 1, lying in the same plane and located in two parallel hogs converging behind the gates into a common smoke hog. The shibers are moved in frames 2, in the upper and lower parts of which there are windows S VI 4, the first serve to pass the air going into the furnace, the second to pass flue gases in the channels of the parallel hogs, in the arches of which there are also windows eleven.

The windows // are covered with a box 5 made up of tightly connected cast parts and separated by a rod 2 with windows 6. In the upper part of the valve, a mechanism 6 is installed to re-slide the slide valves /.

The drawing shows a mechanism actuated by compressed air, but for this purpose, of course, any drive can be used. Cables 7, thrown over the system of guide blocks, are fixed with their ends on the drum 8. When the latter rotates in one direction or another, one of the cables, winding on the drum, lifts the corresponding gate, and at this time the other cable comes off the drum and lowers the second u ber The air (from the fan or self-ventilating) enters through the fitting 9 into the air chamber 10 and, depending on the position of the gates, enters through the windows 3 and // into the corresponding kiln regenerator. The combustion products coming from the furnace pass through the valve along the straight path through the windows 4, without undergoing any additional resistance.

The path of the flue gases is shown in the drawing by a solid arrow, the path of the air is dotted.

Subject and w oreten, and.

A valve for switching air regenerators by means of two mutually connected mutually connected gates in opposite directions, characterized in that the gates are arranged in two parallel hogs converging behind the gates into a common smoke hole and provided with windows 4 in their channels and windows / (i) in the arches covered by a common box 5, which is divided by a partition with windows 3 for admitting air into the hog by alternating movement of the tweezers /.
