Detailed Description
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, and it should be understood that the preferred embodiments are described herein for purposes of illustration and explanation, and not limitation.
As shown in fig. 1 and 2, the two-stage adjustable water inlet flap valve comprises a base 2 provided with a water through hole 1, wherein a first-stage flap valve 3 is arranged on the base 2, so that water passing through the base 2 enters from the first-stage flap valve 3, the first-stage flap valve 3 comprises a first flap valve cover 31, a first flap valve seat 32 and a first-stage through hole 33, the first flap valve seat 32 is arranged on the base 2, so that the first-stage through hole 33 is coaxially arranged on the water through hole 1, water passing through the base 2 enters through the first-stage through hole 33, meanwhile, the height of the first flap valve cover 31 can be adjusted, so that the water flow of the water entering from the first-stage through hole 33 can be controlled, the space of the first-stage through hole 33 is larger than the aperture of the water through hole 1, so that the water passing through the water through hole 1 can be totally entered from the first-stage through hole 33, and the. The first-stage flap door 3 is provided with a second-stage flap door 4, the second-stage flap door 4 comprises a second flap door cover 41, a second flap door seat 42 and a second-stage through hole 43, the second-stage through hole 43 is formed in the first flap door cover 31 and is coaxial with the first-stage through hole 33, and the second flap door 42 is installed on the first flap door cover 31, so that when the first flap door cover 31 is closed, the second flap door cover 41 is opened to enable water to enter from the second flap door cover 41, and the first flap door cover 31 and the second flap door cover 41 are opened simultaneously to enable water to enter from the first flap door cover 31 and the second flap door cover 41 simultaneously, so that impact force of water flow on the flap door is reduced, and water inflow is adjusted. Meanwhile, the aperture of the second-stage through hole 43 is smaller than that of the first-stage through hole 33, so that the second-stage flap valve 4 is arranged on the first-stage flap valve 3, the second-stage flap valve 4 is smaller, the impact force of water borne by the flap valve is smaller, and the design can enable water flow to cause more impact force on the first-stage flap valve 3, so that the impact force on the second-stage flap valve 4 is reduced, and the flap valve is protected.
In this embodiment, the first flap cover 31 is rotatably installed on the first flap seat 32 through a rotating shaft, the first flap seat 32 is provided with a stroke upright post 34 capable of ascending and descending, the top end of the stroke upright post 34 is fixedly connected with the first flap cover 31 and is in transmission connection with a motor, so that the first flap cover 31 can be controlled to be opened at an angle by controlling the ascending and descending of the stroke upright post 34 through a driving motor, and the water inflow can be adjusted.
