Abstract:
A valve, comprising a valve body (200), a valve plate (420), and an actuating mechanism (100). The valve body (200) comprises two plates (211, 212) that are parallel and symmetrical to each other and correspondingly provided with medium inlet/outlet holes; sealing rings a (311, 312) are symmetrically arranged on the inner surfaces of the two plates (211, 212) of the valve body, and the medium inlet/outlet holes of the two plates (211, 212) of the valve body are completely located in circumferentially closed holes of the sealing rings a (311, 312); the valve plate (420) has a smooth surface and is tightly sandwiched between the sealing rings a (311, 312) when the valve is in a closed state; fastening structures surround the radial peripheries of the sealing rings a (311, 312) and are provided on the two plates (211, 212) of the valve body (200) so as to clamp the two plates (211, 212) and/or the sealing rings a (311, 312) of the valve body (200); and the degree of clamping of at least a part of each fastening structure can be adjusted in a direction perpendicular to the surface of the valve body (200). By means of a simple and reasonable structure design, compacting forces of corresponding parts of the sealing rings can be conveniently and timely adjusted outside the valve and the sealing rings can be replaced outside the valve, such that internal leakage of the valve would not occur, and multiple existing valves can be replaced with the valve.
