Description
Technical field
The utility model is related to a kind of hydraulic turbine, particularly a kind of aeration valve on the hydraulic turbine.
Background technology
Conventional air supplement of turbine valve is the function that automatic inflating device is realized by the principle of differential pressure of atmospheric pressure, negative pressure and spring,
When atmospheric pressure and negative pressure collective effect power are more than the active force of spring, valve shaft downward actuation, valve disc is opened, and is filled into air, is made
Negative pressure pressure reduces.When atmospheric pressure and negative pressure collective effect power are less than the active force of spring, valve shaft is acted upwards, and valve disc is closed
Close.But after valve disc opening, after air supply passage connection, under acting force of the spring effect, the air supply passage area of formation is smaller, and
Tonifying Qi demand is big, it is necessary to the air velocity passed through is higher, and the sound of uttering long and high-pitched sounds can be produced when air velocity exceedes certain value.Meanwhile,
Existing aeration valve is complicated, and parts are more, and maintenance changes extremely inconvenient, and operation maintenance and manufacturing cost are higher.
Utility model content
The purpose of this utility model be just to provide one kind can automatic inflating device, prevent howling produce be used for the hydraulic turbine
Aeration valve.
The purpose of this utility model realized by such technical scheme, a kind of aeration valve on the hydraulic turbine,
Including valve body, the upper surface of the valve body is provided with bonnet, sets flexible in the lower section of the bonnet and in valve body
Air supply mechanism, the air supply mechanism is connected with the bonnet, and tonifying Qi hole, the air supply mechanism and institute are provided with the bonnet
State tonifying Qi hole corresponding and cover the tonifying Qi hole.
Wherein, the air supply mechanism includes valve rod, and the valve rod is vertically arranged and through bonnet central, on the valve rod
And rubber slab is provided with below bonnet, the rubber slab covers the tonifying Qi hole, set respectively at the two ends of the valve rod
There is nut.
In order to prevent rubber slab from falling and control rubber slab deflection, set on the valve rod and below rubber slab
It is equipped with pressing plate.
Wherein, the tonifying Qi hole is four, and is symmetrical arranged two-by-two along horizontal center line and vertical center line.
By adopting the above-described technical solution, the utility model have it is simple in construction, using reliable, with low cost excellent
Point, is not only able to realize in automatic inflating device, it is therefore prevented that the generation of howling using it, and maintenance changes convenient, operation maintenance
And manufacturing cost is relatively low, the manpower and financial resources in power station is saved.
Brief description of the drawings
Brief description of the drawings of the present utility model is as follows：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 top view.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, but the utility model
These embodiments are not limited to, any improvement or replacement on the present embodiment essence spirit still falls within the utility model
Claim scope claimed.
Embodiment 1：As shown in Figure 1, 2, a kind of aeration valve on the hydraulic turbine, including valve body 1, in the valve body 1
Upper surface is provided with bonnet 2, in the lower section of the bonnet 2 and the flexible air supply mechanism of setting, the tonifying Qi machine in valve body 1
Structure is connected with the bonnet 2, and tonifying Qi hole 3 is provided with the bonnet 2, and the air supply mechanism is corresponding with the tonifying Qi hole 3
And cover the tonifying Qi hole 3.
Wherein, above-mentioned air supply mechanism includes valve rod 4, and the valve rod 4 is vertically arranged and through the center of bonnet 2, in the valve
Rubber slab 5 is provided with bar 4 and positioned at the lower section of bonnet 2, the rubber slab 5 covers the tonifying Qi hole 3, the two of the valve rod 4
End is respectively arranged with nut 6.
Further, on the valve rod 4 and pressing plate 7 is provided with below the rubber slab 5.
Wherein, the tonifying Qi hole 3 is four, and is symmetrical arranged two-by-two along horizontal center line and vertical center line.
In the utility model, when atmospheric pressure is more than the elastic force of rubber slab 5 with the cavity of resorption negative pressure collective effect power of valve body 1,
The downward elastic deformation of rubber slab 5, air is communicated with the cavity of resorption of valve body 1 by the tonifying Qi hole 3 on bonnet 2 and is passed through air, and with
Being passed through for air, the negative pressure of the lower chamber of valve body 1 reduces and is less than the elastic force of rubber slab 5 with the collective effect power of atmospheric pressure
When, rubber slab 5 is fitted in the presence of elastic force with tonifying Qi hole 3, is closed tonifying Qi hole 3, is so achieved that aeration valve automatic inflating device
Function.
