[0028] The lower surface of the quick relief port flange 3 is rotatably installed with a quick relief valve plate assembly, which is connected with the quick relief port flange 3;

[0029] The quick relief valve plate assembly is clamped with the limiting assembly;

[0030] Further comprising a pneumatic push rod 12, which is installed below the quick relief valve plate assembly, and the pneumatic push rod 12 is in abutment with the limiting assembly.

[0031] Specifically, the quick relief valve plate assembly comprises a rotating shaft 10, the inner ring of the rotating shaft 10 is fixedly installed on the lower surface of the quick relief port flange 3, and the outer ring of the rotating shaft 10 is fixedly installed with a connecting plate 6, which supports the quick relief valve plate;

[0032] The middle part of the connecting plate 6 is installed with a transition block 8, which is rotatably connected with the quick relief valve plate 5, and the transition block 8 plays a connecting role between the quick relief valve plate and the connecting plate.

[0033] Specifically, further comprising an adjusting screw 9, which is installed around the connecting plate 6, and the adjusting screw 9 is connected with the lower surface of the quick relief valve plate 5, adjusting the fitting degree of the quick relief valve plate and the quick relief port.

[0034] Specifically, the upper surface of the quick relief valve plate 5 is provided with a groove, the size of the groove corresponds to the size of the quick relief port flange 3, and the inside of the groove is installed with a sealing gasket 4, which realizes sealing connection with the opening of the quick relief port flange 3;

[0035] Further, in normal production, it is used to block the quick relief port; in abnormal condition, it is separated from the quick relief port to make the material relief.

[0036] Specifically, the connecting plate 6 is installed with a clamping plate 7 away from the rotating shaft 10.

[0037] Specifically, the limiting assembly comprises a rotating connecting rod 2, the upper end of the rotating connecting rod 2 is hinged with the fixed block 1, and the lower end of the rotating connecting rod 2 is fixedly connected with the swing rod 11;
