the packing layer is tightly pressed by the pretightening force provided by the packing gland and the gland bolt, so that the packing layer is tightly attached to the valve plate.
Preferably, the packing layers are arranged around the valve plate.
Preferably, the filler layer is a plurality of layers, especially 3 layers.
Preferably, the packing gland is mated with the packing layer interface.
Preferably, the packing layer is a graphite packing layer, for example, a 10 x 10mm graphite packing layer is manufactured.
Preferably, the packing box and the packing gland are of a one-step processing and forming structure.
Preferably, the gland bolts are 3 sets of M10 bolts.
Through the technical scheme, the utility model has the following beneficial effects:
after the packing layer is tightly abutted against the packing gland, the pre-tightening force is provided by the gland bolts, so that the packing layer is tightly abutted against the valve plate to achieve the sealing purpose, the strength of the packing box and the packing gland is improved, the specification standard of the packing layer is optimized again, the packing layer is added on the periphery of the valve plate, the valve plate is sealed more reliably, the purpose of reliable sealing is achieved, the on-site ash leakage is reduced, the technical problem that the ash discharge valve leaks a large amount of fly ash from the sealing position of the valve plate is solved, the leakage of fly ash in the ash bucket of the bag-type dust collector can be effectively prevented, the running environment of on-site equipment is improved, and the packing valve is simple in structure and reliable in sealing.

Detailed Description
The packing sealing device of the ash discharge valve as shown in fig. 1, 2, 3 and 4 comprises a gland bolt 1, a packing gland 2, a valve plate 3, a packing box 4 and a packing layer 5. The packing layer 5 is positioned in the packing box 4; preferably, the packing layers 5 are multiple layers, such as adding three packing layers 5; the packing layer is tightly pressed by the pretightening force provided by the packing gland 2 and the gland bolt 1, so that the packing layer 5 is tightly attached to the valve plate 3, and the sealing purpose is achieved.
Preferably, the packing layer 5 is a graphite packing layer with a thickness of 10 x 10 mm.
Preferably, the packing box 4 and the packing gland 2 are of a one-step processing and forming structure of a milling machine.
Preferably, the gland bolts are 3 sets of M10 bolts.
The utility model improves the existing valve plate seal, so that the seal is more reliably expressed in:
1. the original asbestos rope filler with the diameter of 2mm is transformed into a graphite packing with the diameter of 10mm, so that the sealing effect is enhanced.
2. The original stuffing box structure is optimized, and a 50mm thick steel plate is directly processed and formed on a milling machine, so that the defects of low strength and easy deformation of the original stuffing box are overcome. The stuffing box is shown in front view from above and right in fig. 3, left side view and bottom plan view.
3. The original 2 groups of packing gland bolts are optimized and transformed into 3 groups of M10 bolts, so that the packing is more uniformly stressed and the sealing effect is better.
