Flange welding is sealed, at least two apertures are circumferentially evenly arranged on the endoporus and sealing surface of sealing flange.
As the further scheme of the present invention, the aperture is made of exhausting-gas hole one and exhausting-gas hole two, exhausting-gas hole one and row
Stomata two is connected with annular groove, and the quantity of exhausting-gas hole one and exhausting-gas hole two is generally 3~24, exhausting-gas hole two and horizontal direction
Angle be 10 °~30 °, the center line of exhausting-gas hole one is vertical with the sealing surface of sealing flange, and exhausting-gas hole one is located at elastic packing
The lower section of body, and it is exposed at the outside of elastic sealed body.
As the further scheme of the present invention, the quantity of the taper pin is two, the angle between two taper pins is 90 °~
150 °, two taper pins use the asymmetric arrangement in position.
As the further scheme of the present invention, annular groove is connected with atmospheric isolation and with air admission hole.
The beneficial effects of the invention are as follows：The vacuum hopper cone valve sealing protection adjusting apparatus, simple in structure, design is reasonable,
Substantially reduce seal and surrounding temperature, the operating temperature for ensureing seal in allowed limits, extends its use
Service life.Ensure the accuracy of alignment of cone valve after seal is replaced using the method for taper pin positioning at the same time, when reducing replacement seal
Centering adjustment time.

Embodiment
The present invention is further elaborated with reference to the accompanying drawings and embodiments.
As shown in Figs. 1-2, a kind of vacuum hopper cone valve sealing protection adjusting apparatus, including at least cylinder 1, receiving hopper 5 and
Cone valve 6, cylinder 1 are fixed with locating flange 3 by bolt group 1, and cylinder 1 and the flange of receiving hopper 5 pass through bolt group 2 10
It is fixed；Fixed between the locating flange 3 of the cylinder 1 and the flange of receiving hopper 5 using taper pin 4, sealing flange 8 and tremie pipe 9
Between install gasket 12, gasket 12 is by 3 11 fixing seal of bolt group on the flange of 5 lower part of receiving hopper；Cylinder 1
Piston rod is connected with cone valve 6, the lower end installation elastic sealed body 7 of cone valve 6；The upward convection current of high-temperature gas is had from tremie pipe 9
And radiation, in order to protect elastic sealed body 7, air admission hole 13 is radially provided with along sealing flange 8, is set along 8 circumferencial direction of sealing flange
There is annular groove 14, annular groove 14 is welded by cover board 17 and sealing flange 8, and annular groove 14 connects with atmospheric isolation and with air admission hole
It is logical；At least two apertures are circumferentially evenly arranged on the endoporus 19 and sealing surface 18 of sealing flange 8.The aperture is by exhausting-gas hole
