Abstract
A combined type anti-jamming sealing device for a fireproof valve is composed of a valve body side plate, supporting strips, spring pieces, blades, a copper sleeve and a blade rotating shaft. The utility model relates to a simple structure, with low costs, rotate nimble, the good anti-sticking sealing device of leakproofness.
Description
Technical Field
The utility model relates to the field of mechanical parts, which is applicable to a fire-proof valve as a core device of a building ventilation and smoke exhaust system.
Background
The fire-proof valve is used as a core device of a building ventilation and smoke exhaust system, and the safety and reliability of the operation of the fire-proof valve are very important. The combined type anti-jamming sealing device is used as an important part of the fire-proof valve, the realization of flexible opening or closing of the blades and the realization of good sealing performance selection reasonability of the valve are very important, and if the device with good rotation flexibility and excellent sealing performance cannot be reasonably designed, the situation that jamming and smoke leakage danger easily occur in the opening and closing process of the fire-proof valve can be caused, and the safety reliability and the personal safety of the operation of other equipment are seriously influenced.
At present, most of domestic fireproof valve manufacturers directly adopt support bars to press and rivet the support bars on a valve body side plate. By adopting the structure, the structure has two disadvantages, namely, the contact area between the supporting strips and the bottom edge of the blade is large, the friction force is large in the rotating process of the blade, the elasticity of the supporting strips is poor, and the flexible rotation of the bottom edge of the blade cannot be realized through deformation, so that the phenomenon of jamming is easy to occur; however, if the form and position tolerance is large in the manufacturing process of the bottom edge of the blade, the gap between the bottom edge of the blade and the supporting strip is too large, and smoke leakage is easily caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming above-mentioned technical defect, provide a simple structure, with low costs, rotate nimble, the good anti-sticking sealing device of leakproofness.
In order to achieve the above object, the utility model adopts the following technical scheme: a combined type anti-jamming sealing device for a fireproof valve comprises a valve body side plate (1), a supporting strip (2), a spring piece (3), a blade (4), a copper sleeve (5) and a blade rotating shaft (6); the valve is characterized in that the spring leaf (3) is buckled on the supporting bar (2), the supporting bar (2) is fixed on the valve body side plate (1) through a press riveting process, the copper sleeve (5) is installed on the supporting bar (2) passing through the opening, the blade (4) is fastened on the blade rotating shaft (6), the blade rotating shaft (6) penetrates through the spring leaf (3) passing through the opening to be installed in the copper sleeve (5), and the blade rotating shaft (6) is driven to rotate through a power system and a transmission mechanism to open or close the blade (4). The spring piece (3) is made of 0.2mm stainless steel and pressed into an arc-shaped surface structure.
Due to the adoption of the technical scheme, the fireproof valve is more flexible to adjust and has better sealing performance.

Detailed Description
The present invention will be further described with reference to the accompanying drawings without limiting the scope of protection.
A combined type anti-jamming sealing device for a fireproof valve comprises a valve body side plate (1), a supporting strip (2), a spring piece (3), a blade (4), a copper sleeve (5) and a blade rotating shaft (6); the valve is characterized in that the spring pieces (3) are buckled on the supporting strips (2), the supporting strips (2) are fixed on the valve body side plate (1) through a press riveting process, the copper sleeve (5) is installed on the supporting strips (2) passing through the opening, the blades (4) are fastened on the blade rotating shafts (6), and the blade rotating shafts (6) penetrate through the spring pieces (3) passing through the opening and are installed in the copper sleeve (5). The blade rotating shaft (6) is driven to rotate through a power system and a transmission mechanism, so that the blade (4) is opened or closed. The spring piece (3) is made of 0.2mm stainless steel and pressed into an arc-shaped surface structure. By adopting the scheme, the contact area with the bottom edge of the blade is reduced to the maximum extent, the friction force is effectively reduced, the blade is flexibly opened and closed, the elasticity of the spring piece is good, the deformation recovery capability is strong, in the rotating process of the blade, the extruded spring piece can rapidly recover the deformation after the blade is adjusted in place, and the blade is always tightly attached to the bottom edge of the blade in the fully closed state, so that the smoke leakage is prevented, and a good sealing effect is achieved.
Therefore, the utility model relates to a simple structure, with low costs, rotate nimble, the good anti-sticking sealing device of leakproofness.
