Description
Technical Field
The utility model relates to a sealing device technical field especially relates to an axial seal structure.
Background
At present, the mode of generally adopting steam heat transfer in heat exchange device adopts the heat exchanger of steam heat transfer mode, can produce a large amount of comdenstion water in the use, and when the comdenstion water can not in time be discharged, partial heat exchange tube can soak in the comdenstion water, leads to the great reduction of heat transfer effect of heat exchange tube, and how to seal the use that does not influence equipment with the comdenstion water is the problem that needs to solve at present urgently.
The contact surface of the valve body and the valve clack is usually set to be a plane with a larger area, two hard planes are in contact sealing, substances or impurities generated in the waste gas treatment process are easily accumulated on the cover plane under the high-temperature and high-pressure states, so that the contact surface is not tightly matched with the valve clack, the sealing performance is reduced, and on the other hand, the steam pipelines can bring larger expansion force and impact force to a sealing gasket in the pipeline during operation due to high medium temperature, high pressure and high flow speed, so that the sealing element at the butt joint is extremely easy to age, and the sealing element is often replaced inconveniently.
In the utility model with the patent number CN207018689U, a steam pipeline sealing device is disclosed, which is not suitable for the sealing of the rotary heat exchange method proposed in the present embodiment.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides an axial seal structure, aims at solving the problem that the produced comdenstion water of steam heat transfer process was revealed among the prior art.
In order to achieve the above object, the utility model provides an axial seal structure, include: a pipe flange assembly, a lens gasket sealing assembly, a double-clamping sleeve sealing assembly and a rotating part; and the two sides of the rotating part are sequentially connected with a double-clamping sleeve sealing assembly, a lens pad sealing assembly and a connecting pipe flange assembly.
Preferably, the lens gasket sealing assembly comprises a compression nut, a sealing ring, a lens gasket, a threaded joint and a connecting pipe; the compression nut is sleeved outside the connecting pipe; a sealing ring and a threaded joint are arranged in a gap between the compression nut and the connecting pipe; the lens pad is arranged between the sealing ring and the threaded joint.
Preferably, the adapter is detachable.
Preferably, the outlet of the connecting position of the sealing ring and the connecting pipe is sealed by adopting sealing welding.
Preferably, two ends of the rotating part are connected with the double-cutting-sleeve sealing assembly in a detachable sealing connection mode.
The beneficial effects of the utility model specifically include:
