Valve

Abstract

Disclosed is a valve, comprising: a housing (1), the housing (1) being internally provided with a passage passing through the housing (1); an inner valve seat (2), the inner valve seat (2) being disposed in the passage and sealedly connected to the housing (1); a flange (3), the flange (3) being located at one end of the housing (1); a valve core (4), the valve core (4) being movably arranged in the passage and located on the side of the inner valve seat (2) away from the flange (3); and a driving member (5), wherein the driving member (5) passes through the housing (1), and drives the valve core (4) to move towards the flange (3) to press against the inner valve seat (2) to close the passage or drives the valve core (4) to be separated from the inner valve seat (2) to open the passage. When the valve is closed, the valve core (4) applies a pressing force towards a container to the inner valve seat (2), such that the sealing effect is better.
