Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, the present embodiment discloses a flush limiting valve, which may include a liquid inlet pipe 10, a liquid outlet pipe 20, and a sealing cavity 30 respectively communicated with the liquid inlet pipe 10 and the liquid outlet pipe 20, wherein a pipe orifice of the liquid inlet pipe 10 is higher than a pipe orifice of the liquid outlet pipe 20, the sealing cavity 30 is provided with a hinge shaft 41, the hinge shaft 41 horizontally penetrates through the sealing cavity 30, the hinge shaft 41 is located in the sealing cavity 30 and is provided with a baffle 42, the opening and closing of the liquid outlet pipe 20 is controlled by rotating the baffle 42, the hinge shaft 41 is located outside the sealing cavity 30 and is connected with a connecting rod 43, and one end of the connecting rod 43, which is far away from the hinge shaft 41, is connected with a floating ball through a chain.

It should be noted that: liquid inlet pipe 10, drain pipe 20 and sealed chamber 30 are stainless steel material, and it can integrated into one piece or welding form, and the floater material is the aluminum alloy material, and weight is no longer than 28 g. The baffle 42 is made of stainless steel material and is sleeved on the hinge shaft, the shape of the baffle 42 is matched with that of the pipe orifice of the liquid outlet pipe 20, and when the baffle 42 covers the pipe orifice of the liquid outlet pipe 20, the liquid outlet pipe 20 is in a closed state; when the shutter 42 is away from the mouth of the outlet 20, the outlet 20 is in an open position.

As shown in fig. 4, the floating ball device further includes a floating ball chamber 50 and a handle 44, the floating ball chamber 50 is used for placing a floating ball, the floating ball chamber 50 is fixedly connected with the sealing cavity 30, the floating ball chamber 50 is a rectangular through groove, four corners of the bottom of the floating ball chamber 50 are respectively provided with a triangular limiting piece 52, the triangular limiting pieces 52 limit the floating ball to move downwards, a strip-shaped hole 51 is formed in a side surface of the floating ball chamber 50 connected with the sealing cavity 30, the connecting rod 43 is clamped in the strip-shaped hole 51, the handle 44 is fixedly connected with the hinge shaft 41, and the handle 44 is inserted into the floating ball chamber 50.
