Pore plate adjusting gate valve

The utility model belongs to the technical field of regulating valves, and particularly relates to a pore plate regulating gate valve. The check valve comprises a valve body, wherein a valve cavity for fluid to pass through is arranged on the valve body in a penetrating manner; a valve seat with a window is coaxially arranged in the valve cavity; the valve plate is driven by a valve rod with a power source so as to perform linear reciprocating motion along the radial direction of the valve cavity; a forced sealing wedge block is further arranged in the valve cavity, a fit clearance for the valve plate to be clamped in and positioning the position of the valve plate is formed between the forced sealing wedge block and the valve seat, and therefore after the valve plate is clamped in the fit clearance, the valve plate can be tightly pressed on the fit sealing face of the valve seat by means of pressure of the forced sealing wedge block and the valve seat. The sealing effect of the valve can be ensured, good sea
