    FIRE-RESISTANT AND ANTI-SMOKE
    The invention relates to a fire and smoke valve.
    In the state of the art are known fireproof and anti-smoke valves which in the present application are also called fire dampers. Such a fire valve solution is disclosed in the Applicant's prior patent FI 89 333; this fire damper moves the closure flap from an open position to a closed position under the effect of the elastic force of a spring, which allows to close the conduit in case of fire. The solutions of the state of the art use a thermal fuse placed between a spring and a fire damper, this fuse changing dimensions under the effect of heat and releasing the closure flap of the fire damper to place it in a closed position due to the effect of a spring. The closure flap is thus placed in a fully open position in which a loop connected to the closure flap is located next to a thermal fuse in a conduit, which allows the thermal fuse to turn against the handle in a net and to apply on the fire damper the elastic force of a spring located on a rod to place it in the open position. The closure flap of the fire damper is located on a rod, between a conduit and the rod. When the closing flap rotates, the rod rotates and squeezes the spring. In case of fire, the closing flap or closing flap closes the duct when the temperature of the thermal fuse increases and the thermal fuse changes size, which releases the closing flap which can move under the effect of the spring in a position where it closes the conduit.
    In the solutions of the state of the art, the thermal fuse is usually installed near the attachment point connected to the fire damper so that the fixing point is located in an upper position in the device and the fuse The thermal barrier located next to it locks the closure flap in the open position when the thermal fuse rotates against the closure flap handle or against another such piece. It is thus advantageous to place the thermal fuse as high as possible in the structure, because in a high position, the temperature is higher than that prevailing in the lower part of the room, the building or the duct.
    However, there are cases in which the attachment point of the rod can be placed in another position at the bottom of the conduit. In conventional structures, the thermal fuse is also located in said lower position and near the spring. However, it is not advantageous to close the closure flap or the closure flap, because at the bottom, the temperature is considerably lower than that prevailing in the upper part of the closure flap.
    In these circumstances and to avoid this problem, the present application proposes to use at least two pieces of equipment that allow to attach and fix a thermal fuse connected to a closure flap. The first equipment elements according to the invention, which make it possible to fix the thermal fuse, are situated next to a spring connected to a rod and the second equipment elements are situated on the other side of the transverse axis. Y of a fireproof and anti-smoke valve which is preferably also a closure valve, preferably at one end of a rod, which makes it possible to place the thermal fuse in a position as high as possible in a structure where a spring is located in the lower position and where the spring can be reacted when the temperature has reached the highest level because of a fire.
    Thus, the present application has discovered how to avoid said mounting problem by providing a fire damper which has at least two pieces of equipment of a thermal fuse which optionally connect a thermal fuse to a point of attachment, the point of attachment then being located in the upper part of a fire damper or optionally moving another attachment equipment in the lower part of the fire damper. The thermal fuse is thus raised by turning the fire and smoke damping valve by 180 °. Thus, it is possible in all cases of mounting to place the thermal fuse in an optimal location located as high as possible in the structure of the fire damper.
    The scope of the invention includes an embodiment in which the relative locations of the point of attachment of the spring and the thermal fuse and its attachment equipment may be generally modified and be located on opposite sides rather than on the same side of the body. transverse axis Y of the fire and smoke valve. This is possible in cases where for example the fixing position of the spring is located at both ends of the axis of the closure valve. By moving a handle placed at the point of attachment, it is also possible to fix the valve from below and to place the thermal fuse in the upper part of the valve.
    The fire and smoke protection valve according to the invention is characterized by the features presented in the claims.
