Water incoming valve capable of shortening lifting rod and method for shortening lifting rod
The invention discloses a water incoming valve capable of shortening a lifting rod and a method for shortening the lifting rod. The water incoming valve comprises a water incoming valve body, a sealing pad, a floating barrel and a lifting rod shortening mechanism rotatably connected to the water incoming valve body, the water incoming valve ody is provided with a depressurizing hole and a water incoming and outgoing passage, the lifting rod shortening mechanism comprises levers of at least two stages, the levers are in transmission connection stage by stage, the floating barrel is in linkage fit with the first-stage lever of the lifting rod shortening mechanism to form a power body used for driving the lifting rod shortening mechanism to act, and the sealing pad is mounted on the last-stage lever of the lifting rod shortening mechanism and moves along with the lifting rod shortening mechanism when the floating barrel moves up and down so as to close or open the depressurizing hole of the water incoming valve body. The method includes providing the lifting rod shortening mechanism. Length of a lifting rod can be reduced greatly while a lever ratio is acquired, so that increasing of size of the water incoming valve is avoided.
