Related with current house design, there is the potential safety hazard in the installation use of current lampblack absorber. At present, in many high-rise apartments, families of multiple households share the same flue, exhaust pipes of range hoods are connected to the same flue, when fire occurs in the flue, the fire easily enters the room along the pipeline of the range hoods through the flue, and fire disasters are caused, so that the high-rise apartment is extremely unsafe.

To this defect, install the fire prevention check valve on the flue usually, current fire prevention check valve, its defect that exists is: only the middle position of the fireproof check valve is provided with a fusing mechanism, when the flame avoids the middle position, the flame still easily enters the flue, and the fire is not tight enough.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to sell the not enough of product technique on the existing market, provide a many fuse-type fire prevention check valve.

In order to achieve the above object, the present invention takes the following measures:

a multi-fusing type fireproof check valve comprises a check valve air door seat, wherein an oil smoke exhaust hole is formed in the middle of the check valve air door seat, an air door plate for shielding the oil smoke exhaust hole is installed on the check valve air door seat on one side of the oil smoke exhaust hole through a rotating shaft hinge assembly, supporting plates are welded on the check valve air door seats on two adjacent sides of the rotating shaft hinge assembly, supporting rods are welded on the supporting plates on two sides, one ends of the supporting plates on the two sides, which are close to the rotating shaft hinge assembly, are connected with supporting rods in a welding mode, sliding grooves are formed in the supporting plates on the two sides in an inclined mode from one end of each supporting rod to the other end of each supporting rod, pressing rods for extruding and shielding the air door plates on the oil smoke exhaust hole are connected in the sliding grooves in a sliding mode, two ends of each pressing rod are connected to two ends of a tension spring, a separation blade is arranged at one end, the first fusing hook is hooked on the pressure rod, the second fusing hook is hooked with a connecting rod arranged in parallel with the pressure rod, a third fusing hook and a fourth fusing hook which are respectively hooked at two ends of the connecting rod are fixed on the check valve air door seat, and the melting points of the first fusing hook, the second fusing hook, the third fusing hook and the fourth fusing hook are not more than 150 ℃;

the pull rod is sleeved with a spring, one end of the spring is pressed on the support rod, and the other end of the spring is pressed on the first fusing hook.

The utility model has the advantages that: the practicality, low in production cost, novel structure, safe in utilization when meetting the condition of a fire, the effectual adjacent burning things which may cause a fire disaster that has prevented enters into from the chimney passageway indoor, the design of many fusing structures, the fireproof effect is better.

Detailed Description

A multi-fuse type fireproof check valve comprises a check valve air door seat 1, wherein an oil smoke exhaust hole is formed in the middle of the check valve air door seat 1, an air door plate 3 used for shielding the oil smoke exhaust hole is installed on the check valve air door seat 1 on one side of the oil smoke exhaust hole through a rotating shaft hinge component 2, supporting plates 4 are welded on the check valve air door seats 1 on two adjacent sides of the rotating shaft hinge component 2, one ends of the supporting plates 4 on two sides, which are close to the rotating shaft hinge component 2, are welded with supporting rods 5, sliding grooves 4-1 are formed in the supporting plates 4 on two sides in an inclined mode from one end of the supporting rods 5 to the other end, pressing rods 6 used for extruding and shielding the air door plates 3 on the oil smoke exhaust hole are connected in the sliding grooves 4-1 in a sliding mode, two ends of the pressing rods 6 are connected to two ends of tension springs 7, one end, which is, a pull rod 8 penetrates through the middle position of the support rod 5, a first fusing hook 9-1 and a second fusing hook 9-2 are respectively fixed at two ends of the pull rod 8, the first fusing hook 9-1 is hooked on the pressure rod 6, a connecting rod 10 arranged in parallel with the pressure rod 6 is hooked on the second fusing hook 9-2, a third fusing hook 9-3 and a fourth fusing hook 9-4 which are respectively hooked at two ends of the connecting rod 10 are fixed on the check valve air door seat 1, and the melting points of the first fusing hook 9-1, the second fusing hook 9-2, the third fusing hook 9-3 and the fourth fusing hook 9-4 are not more than 150 ℃.

Wherein the third fusing hook 9-3 and the fourth fusing hook 9-4 are respectively positioned at the position of one fourth of the edge of the air valve seat 1 of the check valve. The structure is designed so that the middle position of the air door seat 1 of the check valve is provided with a fusing mechanism (a first fusing hook 9-1 and a second fusing hook 9-2), and the middle fusing mechanism is still provided with a fusing mechanism (a third fusing hook 9-3 and a fourth fusing hook 9-4) from the middle fusing mechanism to the middle of the two side edges.
