Embodiment Construction
[0012] Referring to the accompanying drawings, the blast furnace body cooling water pipeline pressure test method, its specific technical scheme is:
[0013] 1. Installation of equipment: Install a pipe in the water supply pipe and return water pipe of the blast furnace respectively and set up a quick cut-off ball valve 2 corresponding to the size, and then install a bypass pipe 3 to connect the water supply and return water pipes. Install a quick shut-off ball valve of the corresponding size. The valve core of the quick shut-off ball valve is a metal semi-circular ball with good sealing performance. The opening of the valve is 0°-90°. 0° is a fully closed state, 90° is a fully open state, and a pressure gauge 4 is installed on the water supply and return water pipes to observe the internal water pressure of the pipes, and an exhaust valve 5 is installed at the top of the blast furnace cooling water system. It is responsible for the exhaust work when the pipeline is filled wit...
