The present invention relates to a multi-segment ring packaging sealing device which comprises the following components: an axle sleeve which is formed with an axle hole; a shaft sealing casing which is formed with an accommodation chamber and a middle hole which gets through the accommodation chamber and is used for the pivoting installation of the axle shaft; and a sealing module which is installed in the accommodation chamber in group and comprises a first sealing ring group, a second sealing ring group and a plurality of elastic components. The first sealing ring group and the second sealing ring group are sleeved outside the axle sleeve. The plurality of elastic components are distributed between the first sealing ring group and the second sealing ring group and provide elastic forcefor position compensation so that the first sealing ring group and the second sealing ring group respectively abut against two axially opposite side surfaces in the accommodation chamber. The first sealing ring and the second sealing ring respectively comprise at least one group of sealing ring. Each sealing ring is a multi-segment ring which is obtained through continuously connecting at least three segments of sing ring parts and is installed with an elastic ring body which is installed at the outer margin through encircling. The elastic action of the single ring part is provided for radicalcompensation. Additionally an air duct is formed through the inner hole edge of the sealing ring for preventing the leakage of the fluid through the hole edge in the manufacturing process and ensuring the safety.
Description
technical field [0001] The present invention relates to a packing sealing device, in particular to a multi-stage ring-type packing which can be applied to rotating equipment in sealing occasions with low pressure in the manufacturing process, and improves the anti-leakage function of the manufacturing process fluid on the manufacturing process side of the equipment. Install the sealing device. Background technique [0002] In order to prevent the fluid in the manufacturing process from leaking to the atmosphere side through the gap between the equipment parts and the transmission shaft, the equipment generally installs a set of shaft sealing devices at the end of its casing, so that the transmission shaft can be rotatably pivoted in it, and by The sealing rings in the shaft sealing device are fitted and rubbed against each other, so as to prevent the leakage of fluid during the manufacturing process. [0003] At present, the known cartridge type sealing device mainly has a ...
