[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model.

[0019] As Figs. 1-3As shown, this utility model provides a technical solution: a liquid material conveying device for chemical production, including a material pipeline 1 and a flange pipe 2 installed on the material pipeline 1 upstream of a valve. The flange pipe 2 is set on the horizontal part of the material pipeline 1. The flange pipe 2 is connected to the material pipeline 1 through flanges on both sides. A fixed baffle 3 perpendicular to its own axis is vertically fixed at the center of the flange pipe 2. A flow-blocking plate 4 located inside the flange pipe 2 is provided on both the front and back of the fixed baffle 3.

[0020] A shaft 5 is fixed on the baffle plate 4 and vertically passes through the flange pipe 2. A limiting ring 6 is fixedly connected to the fixed baffle plate 3 at the position corresponding to the baffle plate 4 and is movably sleeved on the shaft 5. The limiting ring 6 is set on the fixed baffle plate 3 near the top and bottom and is symmetrically arranged to ensure the rotational stability of the shaft 5.

[0021] A sealing bearing 7 is fixed on the flange pipe 2 and rotatably connected to the shaft 5. An end cap 8 is fixed at the upper end of the shaft 5. A storage spring 9 is installed between the sealing bearing 7 and the end cap 8 and is movably sleeved on the surface of the shaft 5. The upper and lower ends of the storage spring 9 are provided with connecting parts 901 and are respectively inserted and fixed on the end cap 8 and the sealing bearing 7. After the storage spring 9 is damaged, it can be disassembled and replaced outside the material pipeline 1.

[0022] Working principle:

[0023] By setting a baffle plate 4 that can be torsionally flipped by the force of the accumulator spring 9, the water hammer phenomenon in the liquid material conveying process is weakened. Since the accumulator spring 9 is set outside the flange pipe 2 and does not come into contact with the liquid material in the material pipe 1, it will not be aged or damaged due to corrosion by the liquid material. It has strong durability, and whether it is damaged is obvious at a glance. It is also convenient to replace the damaged accumulator spring 9 individually.
