When an impact force perpendicular to the direction of the water pipe occurs, the base 1, the fixed clamp 2 and the fixed rod 41 move in the direction perpendicular to the water pipe. When the fixed rod 41 and the sliding rod 42 squeeze the piston rod 64, the oil in the inner oil cavity 63 flows into the upper part of the inner oil cavity 63 and the outer oil cavity 62 through the second one-way valve 67.

After that, the high-pressure nitrogen in the outer oil cavity 62 pushes the oil to flow into the inner oil cavity 63 through the first one-way valve 66. The damping spring 68 rebounds and drives the piston rod 64 to rise. The oil squeezed on the upper part of the inner oil cavity 63 flows into the lower part of the inner oil cavity 63 through the first one-way valve 66. The above process is repeated to continuously absorb the impact force, providing protection for the fire water pipe.
