ball valve

Over the long years of our company, we have built up profound production experience based on blast furnace pulverized coal injection technology. The ball valve series products we manufacture, whether national standard or non-standard, are all based on quality. With their excellent air tightness, pressure resistance, compact structural design and low failure rate, they perform outstandingly in terms of economic practicality.

This ball valve displayed by our company has a unique shape like a date pit. In terms of form, ball valves are mainly divided into two types: one is the date pit shape, and the other is the square shape. These two forms of ball valves are widely used in the blast furnace pulverized coal injection systems of domestic iron and steel enterprises. They are installed on the straight blowpipe of the blast furnace, and their main task is to connect the pulverized coal injection lance. When the pulverized coal injection lance is inserted into the blast furnace, these ball valves will automatically open; when the pulverized coal injection lance is pulled out from the tuyere of the blast furnace, the steel balls inside the ball valves will automatically close under the action of the pressure in the blast furnace and their own gravity, effectively controlling the overflow of hot gas in the furnace.

In terms of the connection method between the pulverized coal injection lance and the ball valve, we have adopted a unique quick-install chuck design. When the pulverized coal injection lance is inserted into the tuyere of the blast furnace from the inner hole of the quick-install chuck seat of the ball valve, the internal steel balls will be pushed up by the lance, and a quick connection is made between the quick-connect chuck fixed on the pulverized coal injection lance and with sealed packing and the chuck seat of the ball valve. This design not only improves operation efficiency, but also provides a solid guarantee for the stability and safety of the equipment.

For our company, we not only focus on meticulous work in the details of ball valves, but also carry out comprehensive innovation on the entire blast furnace pulverized coal injection equipment. The arc swirl spray wheel for blast furnace pulverized coal injection developed by us has undergone careful layout in the design of its pulverized coal injection pipe and lance head. The pulverized coal airflow circulation gap between the spherical pulverized coal atomizing disc specially set at the top of the lance head and the end of the lance pipe makes the pulverized coal airflow form an umbrella shape when ejected, and mix with the hot blast of the blast furnace instantly, greatly improving the combustion rate of pulverized coal and the mixing ratio with the hot blast of the blast furnace.

In addition, as Xiangye Environmental Protection Company, our company not only focuses on the production of blast furnace pulverized coal injection products such as emission filters and ball valves, but also strictly controls the material selection, workmanship, quality inspection and after-sales service. Our products have not only won a good reputation in the domestic market, but also undertake the design and installation projects of pulverized coal injection systems and pneumatic conveying systems all the year round.

Our technical team, based on years of experience, continuously innovates and optimizes product performance. For example, the -3 type ball valve we launched allows convenient inspection, replacement and maintenance of both its steel balls and sealing seats. Whether it is the steel balls or the valve body, high-quality materials such as carbon steel or stainless steel can be selected according to the needs of users. This flexibility and customized service enable our products to better meet the needs of different customers.

We are not only producers, but also technology leaders. Our innovations and breakthroughs in blast furnace pulverized coal injection technology have achieved the goals of high coal ratio, uniform injection and low-cost operation. This is not only a victory in technology, but also our firm commitment to the environmental protection cause. We firmly believe that through our efforts and innovation, we can bring higher benefits to iron and steel enterprises and contribute more to the environmental protection cause.
