[0003] However, in some occasions with higher sealing performance, such as the sealing occasions with strict requirements for gas-liquid isolation, that is, when the rotating shaft is rotating, it is required that the grease in the sealing cavity will not leak out, and the It is required that the outside gas will not enter the sealed cavity, which puts forward higher requirements for the sealing device. At present, there is no effective product in this field that can meet the above requirements

Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] The structure of the gas-liquid isolation device provided by the present invention is as follows: figure 1 and figure 2 As shown, it includes at least a moving ring and a static ring. The moving ring is fixed on the shaft sleeve 2 and rotates with the shaft sleeve. The shaft sleeve is fixed on the rotating shaft 1. The static ring is fixed on the equipment end cover 3. The static ring Set on the moving ring and the two rotate relative to each other.
[0020] The moving ring and the static ring are both provided with two, which are respectively the first moving ring 6, the second moving ring 7, the first static ring 8 and the second static ring 9, and the section of the moving ring is C-shaped. , including the first inner ring 19, the first connecting ring 20 and the first outer ring 21, the three are integrated structure, wherein the first inner ring is sle...

The invention provides a gas-liquid isolating device. The gas-liquid isolating device at least comprises movable rings and fixed rings. The movable rings are fixed to a shaft sleeve and rotate along with the shaft sleeve, and the shaft sleeve is fixed to a rotating shaft; the fixed rings are fixed to a device end cover, the movable rings are sleeved with the fixed rings, and each movable ring and the corresponding fixed ring oppositely rotate. The two movable rings include the first movable ring and the second movable ring, and the two fixed rings include the first fixed ring and the second fixed ring. The first movable ring is sleeved with the first fixed ring, the second movable ring is sleeved with the second fixed ring, the first movable ring and the second movable ring are distributed left and right, and a compression spring A is arranged between the first movable ring and the second movable ring. A ring sliding mechanism is installed at the left end of the first movable ring. A connecting sleeve is installed on the device end cover, the first fixed ring and the second fixed ring are sleeved with the connecting sleeve, the first fixed ring, the second fixed ring and the device end cover are fixed through the connecting sleeve, and a sealing cavity is jointly formed among the first fixed ring, the second fixed ring and the device end cover. By means of the gas-liquid isolating device, the sealing performance is quite excellent, and gas-liquid isolating can be achieved.
Description
technical field [0001] The invention provides a gas-liquid isolation device, in particular to a sealing device capable of isolating gas and liquid, and belongs to the technical field of sealing. Background technique [0002] The labyrinth seal is to set a number of annular sealing teeth arranged in sequence around the rotating shaft. A series of interception gaps and expansion cavities are formed between the teeth. device for the purpose. Since there is a gap between the rotating shaft of the labyrinth seal and the end cover of the equipment, there is no solid contact, and thermal expansion is allowed, so it is suitable for high temperature, high pressure, and high speed frequency occasions. This sealing form is widely used in steam turbines, gas turbines, and compressors. , The shaft end of the blower and the seal between stages. In some occasions where the use requirements are relatively strict, the sealing device must not only achieve zero leakage of lubricating oil in ...
