Referring to fig. 1, an embodiment of the present invention provides a fluid pipeline connecting assembly 100, which includes a connecting sleeve 110, a weight 120 and a baffle 130. The fluid conduit connection assembly 100 may be used to transport fluids such as mortar, putty slurry, and the like.

As shown in fig. 1 and 2, the connecting sleeve 110 is provided with a conveying passage 113, two ends of the conveying passage 113 are respectively provided with a feeding hole 111 and a discharging hole 112, an inner wall of the connecting sleeve 110 is provided with a mounting portion 115, the baffle 130 is rotatably connected to the mounting portion 115, and in the rotating process, the baffle 130 alternatively opens or closes the conveying passage 113, and the counterweight 120 is slidably disposed on the baffle 130 for providing a rotating moment to the baffle 130. The mounting portion 115 is a portion of the connecting sleeve 110 for mounting the baffle 130. When the baffle 130 opens the conveying channel 113, the slurry flowing into the feeding hole 111 can flow into the conveying channel 113 and flow out of the discharging hole 112; when the baffle 130 closes the transfer passage 113, the slurry flowing from the inlet hole 111 is blocked by the baffle 130 and cannot flow into the transfer passage 113.

In the present embodiment, the connecting sleeve 110 is a substantially rectangular housing structure, the conveying channel 113 is defined by the inner wall of the connecting sleeve 110, and the feeding hole 111 and the discharging hole 112 are respectively disposed on two opposite wall surfaces of the connecting sleeve 110. In addition, the connecting sleeve 110 may also be a casing with other polygonal shapes, a cylindrical casing, an oval casing or a casing with other shapes, and may be specifically configured according to implementation requirements. In this embodiment, the baffle 130 may be provided at a position of the conveying passage 113 adjacent to the feeding hole 111. The baffle 130 can alternatively rotate to a first position and a second position, in the first position, as shown in fig. 2, the baffle 130 can abut against the inner wall of the connecting sleeve 110 and cover the whole feeding hole 111 to block the whole feeding hole 111, thereby closing the conveying passage 113; in the second position, as shown in fig. 3, the shutter 130 may be rotated away from the feed opening 111 to open the conveyance path 113. The shape of the baffle 130 can be adapted to the shape of the longitudinal section of the conveying channel 113.

When the inlet aperture 111 is not in flow or the flow rate of the incoming fluid is too low to be sufficient to blow the baffle 130, the baffle 130 is normally in the first position; when the inlet hole 111 is filled with fluid at a certain flow rate, the baffle 130 opens the conveying channel 113 under the impact force of the fluid, and the fluid in the inlet hole 111 can flow into the conveying channel 113 and flow out from the outlet hole 112.
