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 practicability. The drawing below shows a uniquely designed jujube-shaped ball valve. Classified by appearance, there are mainly two types of ball valves: one is the jujube-shaped ball valve you see here, 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 automatically closes 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 safer. Specifically, when the pulverized coal injection lance is inserted into the tuyere of the blast furnace from the inner hole of the quick-connect chuck seat of the ball valve, the steel ball inside the ball valve is pushed up by the lance. Then, through the quick-connect chuck fixed on the pulverized coal injection lance and with sealing packing properly installed, it realizes quick connection with the quick-connect 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 for daily inspection, replacement and maintenance. The steel ball and the valve body 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 equipment for blast furnace pulverized coal injection. Among them, this utility model relates to an equipment technical solution of an arc swirl spray wheel for blast furnace pulverized coal injection. This solution consists of a pulverized coal injection pipe and a lance head. The top of the lance head is equipped with a spherical pulverized coal atomizing disc, and there is a pulverized coal airflow circulation gap between the atomizing disc and the end of the lance pipe. With this design, the pulverized coal airflow flows through the pulverized coal injection lance pipe to the lance head, and then is shunted by the atomizing disc and sprayed out in an umbrella shape, forming an atomized pulverized coal flow. These tiny atomized pulverized coal flows instantly mix with the hot blast of the blast furnace, enabling the pulverized coal to be fully burned. This technology has the advantages of reasonable structure, convenient use, improved pulverized coal combustion rate and mixing ratio between pulverized coal and blast furnace hot blast.
