Problems solved by technology
However, due to the lack of a clear staggered arrangement, it is easy to cause the airflow to flow to the closer channel, resulting in the accumulation of airflow and pressure increase in the local channel.

Embodiment Construction
[0032] Below in conjunction with accompanying drawing, the present invention is described further below:
[0033] The present invention includes: an annular sheet body 1, the sheet body 1 is provided with mounting holes 2, a plurality of bosses 7 are distributed on the front of the sheet body 1, the bosses 7 are T-shaped structures, and the bosses 7 are evenly distributed along the circumferential direction , the boss 7 is provided with at least two circles or more, if there are four circles, the gap between the adjacent bosses 7 forms an airflow channel with multiple bends, the sheet body 1 is an annular sheet metal part, and the boss 7 is It is formed by stamping the reverse side of the sheet body 1 to the front side, that is, the flame retardant sheet is a stamping part.
[0034] as attached figure 1 to the attached Figure 4 As shown, it is the first embodiment of the present invention, the bosses 7 of different circles on the sheet body 1 are arranged in parallel in the...

The invention relates to a flame retardant sheet for an explosion-proof valve, which comprises a ring-shaped sheet body, on which mounting holes are arranged, and several bosses are distributed on the front of the sheet body, the bosses are in a T-shaped structure, and the bosses are along the circumferential direction. Evenly distributed, the bosses are provided with at least two circles, and the gap between the adjacent bosses forms an airflow channel with multiple bends. The bosses of different circles on the sheet are arranged side by side in the radial direction, and the bosses are arranged in the same radial direction. The direction is arranged in the same direction from the outer edge to the inner edge, and the bosses are arranged symmetrically and crosswise on the same circle; compared with the prior art, the present invention has a novel and simple structure, which can prolong the distance and time of airflow and flame passing, and at the same time The airflow and the walls of the flame-retardant sheet can be fully contacted for heat exchange, thereby reducing the temperature of the airflow and completely extinguishing the flame, which solves the problems that the flame-retardant sheet of the existing explosion-proof valve cannot quickly, effectively, and reliably extinguish the flame and relieve pressure.
Description
[Technical field] [0001] The invention relates to the technical field of explosion-proof valves, in particular to a flame-retardant sheet of an explosion-proof valve. [Background technique] [0002] At present, when the diesel engine is running, heat will be generated in the crankcase due to the movement of the crankshaft, connecting rod and piston, etc. When the diesel engine fails, the temperature and pressure in the crankcase will rise sharply, causing oil and gas deflagration, resulting in High pressure airflow and high temperature flame, and the explosion-proof valve is set on the crankcase box, which can release the pressure in the crankcase, while releasing the pressure, it can prevent the flame from passing through and then close to prevent air from entering. [0003] Chinese Invention Patent No. 200710300274.2 discloses a "flame-retardant sheet for explosion-proof valve". The flame-retardant sheet for explosion-proof valve is a circular sheet-shaped sheet body. The ...
