Beschreibung
Zusammenfassung:	The invention discloses a sealing structure and method of a bypass pressure release valve. The sealing structure comprises a valve closing body capable of being driven by an electromagnetic unit, and a protective cover movably coating the outer periphery of the valve closing body, wherein a radial sealing piece is arranged between the valve closing body and the protective cover; the inner periphery part of the radial sealing piece is fixedly connected with the valve closing body; the outer periphery part of the radial sealing piece slidingly fits the protective cover, and cooperates with the protective cover to achieve the interference fit under the condition of no current and in a period of time of just electrification of the electromagnetic unit so as to realize the sealing; and then, the outer periphery part of the radial sealing piece and the protective cover are in clearance fit to release the sealing. The sealing structure is proper in sealing length, can effectively prevent excessive wear of the sealing piece, is excellent in sealing effect, is excellent in positioning effect of the sealing piece, and can be combined with electromagnetic force of the electromagnetic unit to enable the opening of the bypass pressure release valve to become smoother.
