Abstract

An inlet valve with a shortened lifting lever and a method of shortening the lifting lever, wherein the inlet valve includes a main body with a compression hole and a waterway, a sealing pad and a float, wherein further comprising a shortened lifting lever mechanism that is rotatably connected to the main body. The shortened lifting lever has at least two stages of levers connected in driving manner. The float is coupled to the first stage lever in a linking manner, thus forming a dynamic body to drive the shortened lifting lever to move; the sealing pad is assembled to the last stage lever. The sealing pad closes the compression hole of the main body of the inlet valve or opens the compression hole with the movement of the shortened lifting lever when the float moves up and down.
