As the further scheme of the present invention, described aperture is made up of exhaust port one and exhaust port two, exhaust port one and exhaust port two are all communicated with circular groove, the quantity of exhaust port one and exhaust port two is generally 3 ~ 24, exhaust port two is 10 ° ~ 30 ° with the angle of substantially horizontal, the center line of exhaust port one is vertical with the sealing surface of sealing flange, and exhaust port one is positioned at the below of elastic sealed body, and is exposed at the outside of elastic sealed body.
As the further scheme of the present invention, the quantity of described taper pin is two, and the angle between two taper pins is 90 ° ~ 150 °, and two taper pins adopt the asymmetric layout in position.
As the further scheme of the present invention, circular groove is with atmospheric isolation and be communicated with inlet hole.
The invention has the beneficial effects as follows: this vacuum hopper cone valve seal protection regulating device, structure is simple, reasonable in design, and seal and temperature around thereof are reduced greatly, and the operating temperature ensureing seal in allowed limits, extends its working life.Adopt the method for taper pin location after changing seal, ensure the accuracy of alignment of cone valve simultaneously, reduce centering regulation time when changing seal.
