ball valve

      In the field of blast furnace pulverized coal injection, we have accumulated many years of rich production experience. All kinds of ball valves we produce, whether national standard or non-standard, have excellent air tightness, strong pressure resistance, compact structure, low failure rate and economical and practical characteristics. The drawing shows a unique design of jujube-shaped ball valve. Classified by shape, there are two main types of ball valves: one is the jujube-shaped ball valve you see, and the other is the square ball valve. These two types of ball valves are widely used in the blast furnace pulverized coal injection systems of domestic iron and steel enterprises, playing a crucial role. They are installed on the straight tuyere of the blast furnace to connect the pulverized coal injection lance. When the pulverized coal injection lance is inserted into the blast furnace, the ball valve opens; when the pulverized coal injection lance is pulled out from the tuyere of the blast furnace, the steel ball inside the ball valve will automatically close under the combined action of the pressure in the blast furnace and its own gravity, thus preventing the hot gas in the furnace from leaking out.

      This ingenious design makes the pulverized coal injection operation more efficient and safe. Specifically, when the pulverized coal injection lance is inserted into the tuyere of the blast furnace from the inner hole of the quick-installation chuck seat of the ball valve, the steel ball inside the ball valve will be pushed up by the lance, and then the quick-connection chuck fixed on the pulverized coal injection lance and sealed with packing will be quickly connected with the quick-connection chuck seat of the ball valve. The smooth completion of this series of actions benefits from the precise design and strict manufacturing process of our products. It is worth mentioning that the steel ball and sealing seat of our Type -3 ball valve are detachable, which brings great convenience to daily inspection, replacement and maintenance. The steel ball and shell can be made of carbon steel or stainless steel according to the user's needs, to ensure that the product can operate stably under various working conditions.

        In addition to ball valves, we are also committed to the research and development of blast furnace pulverized coal injection equipment. Among them, this utility model relates to a technical scheme of arc swirl spray wheel equipment for blast furnace pulverized coal injection. The scheme consists of a pulverized coal injection pipe and a lance head. The top of the lance head is provided with a spherical pulverized coal atomizing disk, and a pulverized coal airflow circulation gap is provided between the atomizing disk and the end of the lance pipe. With this design, the pulverized coal airflow flows through the injection lance pipe to the lance head, and then is shunted by the atomizing disk, spraying out in an umbrella shape to form an atomized pulverized coal flow. These tiny atomized pulverized coal flows instantly mix with the hot blast of the blast furnace, so that the pulverized coal can be fully burned. This technology has the advantages of reasonable structure, convenient use, improving the combustion rate of pulverized coal and the mixing ratio of pulverized coal and blast furnace hot blast.
