When the valve plate 109 is closed, the bidirectional valve seat 102 makes the medium not overflow to the inside, and the valve plate 109 prevents the medium from flowing in at the outlet end of the valve body 101, when the bidirectional valve seat 102 is worn, the bidirectional valve seat 102 can be directly replaced, without replacing the entire valve, so that the use cost is lower, and maintenance is facilitated. In this way, the technical problem that the valve in the prior art is used in some occasions, and slag liquid is left inside, thereby affecting the use effect of the valve, is solved.

[0021] And the valve plate 109 seals the bidirectional valve seat 102 without damaging the bidirectional valve seat 102, and the bidirectional valve seat 102 is pressed to widen the sealing line and increase the sealing when the valve plate 109 is closed.
