WATER INTAKE VALVE WITH SHORTENED LIFT LEVER AND METHOD OF SHORTENING LIFT LEVER OF WATER INTAKE VALVE

摘要

Disclosed is a water intake valve with a shortened lift lever, comprising a water intake valve main body (1) provided with a relief hole (11) and a water intake/discharge channel, a sealing gasket (3) and a float (2), and further comprising a lift lever shortening mechanism rotatably connected to the water intake valve main body (1), wherein the lift lever shortening mechanism comprises at least two stages of lever, the at least two stages of lever being connected rotatably together stage by stage; the float (2) is coupled and fitted with a first stage lever (4) of the lift lever shortening mechanism, forming a power body used for driving the action of the lift lever shortening mechanism; the sealing gasket (3) is mounted at the final stage lever (5) of the lift lever shortening mechanism and closes or opens the relief hole (11) of the water intake valve main body (1) along with the movement of the lift lever shortening mechanism when the float (2) acts downward or upward. The invention further relates to an operating method for the water intake valve with a shortened lift lever.
