1. A valve comprising:
a valve body;
a valve plate; and
an actuation mechanism, wherein
the valve body includes two plates which are parallel to each other and symmetrical and on which medium access holes are correspondingly opened,
first sealing rings are symmetrically provided on inner surfaces of the two plates of the valve body, and the medium access holes on the two plates of the valve body are completely located within circumferentially closed holes of the first sealing rings, the valve plate is tightly sandwiched between the first sealing rings when the valve is closed,
a fastening structure is installed on the two plates of the valve body and clamps the two plates of the valve body and/or the first sealing rings around radial peripheries of the first sealing rings, and
at least a part of the fastening structure can adjust its clamping degree in a direction perpendicular to a surface of the valve body,
the valve plate has two strip-shaped structures extending from both sides of a first end in a direction opposite to an opening direction of the valve plate, a thickness of the strip-shaped structures is a thickness of the valve plate, and outer edges of the strip-shaped structures are on extension lines of outer edges of the valve plate;
in a fully open state of the valve, a position of the first end of the valve plate corresponds to positions of inner edges of the first sealing rings here, a length of the strip-shaped structures is such that ends of the strip-shaped structures in the direction opposite to the opening direction of the valve plate do not fall within the valve body, and meanwhile, a width of the strip-shaped structures makes the strip-shaped structures completely press the first sealing rings at corresponding positions;
the first sealing rings respectively arranged on the two plates of the valve body are connected as a whole at a first end of the valve body where the strip-shaped structures enter and exit the valve body, and tiled to an edge of the first end of the valve body, or a first sealing material is laid in a cavity of the valve body between the edge of the first end of the valve body and the first sealing rings; and the first sealing rings or the first sealing material corresponding to the position of the first end of the valve body is provided with a first inlet and outlet of the strip-shaped structures.
