Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of new type explosion proof overpressure exhaust valve, including
Exhaust valve ontology 1, connecting rod 3 and explosion-proof reinforcing bar 11, the bottom of exhaust valve ontology 1 are equipped with mounting seat 7, and exhaust is lived
Articulated joint 8 is installed on the side outer wall of door body 1, connecting rod 3 is rotatably installed in the inside of articulated joint 8 by shaft 16, and
Returning spring 15 is installed, one end of connecting rod 3 is equipped with valve lid 2 by fixing piece 14, prevents on the two sides outer wall of connecting rod 3
Quick-fried reinforcing bar 11 is fixed on the inside of exhaust valve ontology 1, and exhaust valve ontology 1 is provided with filtering close on the inner wall of upper opening
