Same vibration.Therefore, the valve mechanism of the prior art and operation principle is caused to there are problems that having disadvantages that and be difficult to overcome：
1, since shell tilts, and there are high vibrations, and the sealing life between Blower Housing and rotary shaft to be caused to be dropped
It is low.
2 since Blower Housing tilts, and there are high vibrations to cause between Blower Housing and rotary shaft in sealing structure
Rotary part and stationary parts gap it is excessive, cause leakage rate to increase.
3, material gas is often all toxic gas, leaks into air and pollutes environment, increases haze.
4, material inherently resource, leakage result in wasting.
5, the leakage rate of wind turbine can be increased slowly over time, can not know that leakage rate is increased or let out suddenly in time
Leakage quantity is exceeded suddenly.
6, people could have found after can only increasing leakage rate, then take measures, can not prejudge in advance again, can not accomplish
It is preventive from possible trouble.
7, wind turbine leakage rate will reduce greatly the working efficiency of wind turbine.
Invention content
Technical problem to be solved by the utility model is to provide one kind can eliminate due to rotary shaft and Blower Housing it
Between non-perpendicularity and Blower Housing high vibration fan it is running seal cause adverse consequences make Blower Housing
The sealing structure of stabilized seal is kept in vibration.
Technical solution used by the utility model is：A kind of sealing for making Blower Housing keep stabilized seal in vibration
Structure, be for being fixedly connected with the impeller by Blower Housing, the impeller being arranged in Blower Housing and one end, it is another
On the wind turbine that end stretching Blower Housing and the shaft for connecting bearing with bearing cap by bearing block are constituted, in the Fan casing
Junction between body, shaft and bearing cap is provided with elastic sealing structure, and the elastic sealing structure includes：Pass through spiral shell
Silk is fixedly connected on the sealed connecting component on the Blower Housing, and fixing sleeve is in the shaft and closes at the bearing cap
Revolving part is sealed, and the sealing for being sleeved on sealing revolving part outside and being fixed on the bearing cap being slidably matched is static
Part is provided with elastic sealing element between the sealed connecting component and sealing static element.
The elastic sealing element be one end be fixedly connected on the sealed connecting component, the other end be fixedly connected on it is described
Seal the metal bellows on static element.
The elastic sealing element be one end be fixedly connected on the sealed connecting component, the other end be fixedly connected on it is described
Gum sleeve or canvas sleeve on sealing static element or plastic bushing.
The utility model makes Blower Housing keep the sealing structure of stabilized seal in vibration, has the following advantages that：
Although 1, shell tilts, and there are high vibrations, completely by soft flexible part (metal bellows, rubber
Sebific duct, canvas or plastic tube) it is absorbed, it is ensured that sealing stable operation improves the service life of sealing structure.
2, due to sealing can stable operation, the rotary part of sealing and stationary parts gap can be controlled, effectively
Reduce leakage, or even is made zero leakage.
3, material gas is all often toxic gas, and zero leakage, which does not just leak into air, pollutes environment, also not
Haze can be increased.
4, material inherently resource, zero leakage would not cause to waste.
5, the leakage rate of wind turbine will not be increased slowly over time and voluntarily.
6, leakage can prejudge in advance, take and take measures, accomplish to be preventive from possible trouble.
7, wind turbine gas material zero leakage, to improve the working efficiency of wind turbine.
8, the transformation prior art is very convenient, and interchangeability is strong, and input is small.
9, it can accomplish non-maintaining, reduction maintenance cost after being transformed.

Specific implementation mode
Blower Housing is set to keep the close of stabilized seal in vibration the utility model with reference to embodiment and attached drawing
Seal structure is described in detail.
As shown in Fig. 2, the utility model makes Blower Housing keep the sealing structure of stabilized seal in vibration, it is to be used for
It is fixedly connected with the impeller 12 by Blower Housing 13, the impeller being arranged in Blower Housing 13 12 and one end, the other end
It stretches out Blower Housing 13 and is connected on the wind turbine of the composition of shaft 11 of bearing 19 by bearing block 18 and bearing cap 17, described
Junction between Blower Housing 13, shaft 11 and bearing cap 17 is provided with elastic sealing structure, the elastic sealing structure
Include：It is fixed by screws the sealed connecting component 21 on the Blower Housing 13, fixing sleeve is in the shaft 11
And the sealing revolving part 15 at the bearing cap 17 is closed on, and what is be slidably matched be sleeved on the outside of the sealing revolving part 15 and solid
