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...

Abstract

The invention discloses a blast furnace body cooling water pipe pressure test method. The technical scheme of the method comprises the following steps: mounting equipment, opening a valve, starting a water pump, adjusting the valve, closing the valve and carrying out a pressure test. According to the blast furnace body cooling water pipe pressure test method disclosed by the invention, the method is simple, a temporary water replenishing pipe is not required for water replenishing, the watering speed of the pipe is high, the pipe boosting can be completely adjusted through the opening degree of the valve and the operation can be strictly carried out according to the specifications, so that the mounting time is saved, the mounting materials are saved and the project construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pressure testing of blast furnace cooling water pipelines in metallurgical systems, in particular to a pressure testing method for blast furnace body cooling water pipelines, which is used for pressure testing of blast furnace body cooling water pipelines. Background technique [0002] In the pipeline construction of the existing metallurgical industry, the pressure test of the cooling water pipeline of the blast furnace body is to install a temporary supplementary water pipeline, and at the same time install a valve on the furnace pipeline. Huge, and considering the special construction conditions on site, the temporary pipelines installed are easily damaged. This kind of pressure testing method is labor-intensive, time-consuming and material-intensive, and at the same time, because the pressure of the water supply source is generally very small, the secondary pressurization time is very long.
