    However, this type of damper cannot close the flow completely, more or less ventilation air leaks through even if the air-driven damper is completely closed. This means that less air arrives at the places you intend to ventilate and the result is that you have to increase the fan capacity to achieve adequate ventilation. An increase in ventilation also increases the need for energy to heat the incoming air.
    With the present invention it is achieved that air flows in so-called flexible tube can be controlled and varied steplessly from zero to maximum air flow with shut-off valve as follows. the air flows can be controlled and regulated steplessly between full flow or zero in flow. The number of fans in the ventilation system can be reduced and replaced by shut-off valves as described, which provides a flexible and optimal control of the ventilation need and is also an advantage from an energy point of view.
    The invention consists of a circular geometry of steel, plastic or other suitable material. The circle is divided via two joints diametrically towards each other and thus forms two halves of the circle. The smaller semicircle has an outer radius that is slightly smaller than the inner radius of the larger semicircle, this means that the smaller semicircle can be folded into the larger semicircle thus forming a semicircle of the two semicircles. In the open position the two semicircles form a circle, in the collapsible position a semicircle.
    The invention as shown in the accompanying drawing. No. 1 consists of a semicircular steel tube (1) with an inner radius X and another semicircular tube (2) with an outer radius which is slightly smaller than the radius X of the tubular tube (1). The two semicircular tubes are connected by joints (3) which have to function to be able to form either a circle of the shut-off valve (when open) or to form a semicircle (when closed) where one semicircle (2) forms an inner semicircle with the outer semicircle (1).
    To open resp. closing the valve, this can be done through a crank device (7) which is connected to the shaft (4) for manual closing resp. opening of the valves. Alternatively, an electric motor (6) can be connected via motor bracket (4), worm gear (5) for opening resp. closing the valves. The electric motor can be controlled remotely and thus the ventilation in a tunnel system can be controlled from, for example, a control room. In larger mines where tunnel systems make up several kilometers, ventilation of the tunnels is a necessity for operations to be conducted, effective ventilation presupposes that it can be controlled and regulated as needed.
    Drawing no. 2 shows the valve (1) in closed position with so-called stabilizers (5) and (6) and shaft (4) which, when rotated, open or close the valve.
    The stabilizers (5) and (6) have the task of stabilizing the valve when opening or closing. One end of the stabilizer is attached to the tunnel roof and the other end to the circle half (1) of the valve resp. thus the valve is stabilized at opening resp. closing, regardless of whether opening or closing takes place manually or mechanically with an electric motor or other mechanical drive device.
    Drawing No. 3 shows the valve (1) in the open position mounted on a flexible tube placed in a tunnel roof (local roof), the drawing also shows the location and attachment of the stabilizers (5) and (6) in the tunnel roof and in the valve.
    Drawing No. 4 shows, like Drawing No. 3, the valve mounted in a tunnel on a flexible tube, in this drawing the valve is shown in closed position. Drawing no. 4 also shows how the flexible tube is squeezed between the two semicircles (1) and (2) and thus the air flow in the flexible tube is switched off. The valve can be adjusted steplessly from fully open as shown in drawing no. 3 to fully closed as shown in drawing no. 4.

    1. A patent shut-off valve consisting of two (2) semicircles, an outer and an inner, articulated joint at the end of the semicircles. CHARACTERIZED IN THAT the inner semicircle can be turned into the outer semicircle via the joints and thus form a semicircle of the two semicircles. CLAIM 2 Shut-off valve according to claim 1 CHARACTERIZED IN THAT the shut-off valve can form either a semicircle or a circle. CLAIM 3 Shut-off valve according to claims 1 and 2 CHARACTERIZED IN THAT the shut-off valve can change geometry steplessly from circle to semicircle.
