Nurtured in the crucible of technology and industry, the various ball valves meticulously developed by our company, whether standard or non-standard, embody unique technical essence and practical value. These ball valves feature excellent air tightness, indestructible pressure resistance, and a compact structural design, resulting in low failure rates and cost-effectiveness, making them reliable assistants in the blast furnace pulverized coal injection systems of steel enterprises.

      In the drawings, we showcase the uniquely shaped date-pit ball valve. Morphologically, ball valves come in two forms: one is the date-pit shape, and the other is the square shape. Both types of ball valves have been widely applied in the practices of domestic steel enterprises. They are installed on blast furnace tuyeres, serving the critical task of connecting the coal injection lance. When the coal injection lance is inserted into the blast furnace, the ball valve opens, and when the lance is withdrawn from the blast furnace tuyere, the internal ball automatically closes under the pressure of the blast furnace and its own gravity, ensuring that the internal heat does not escape.

       The secret behind this automatic control lies in the precision design of the ball valve. When the coal injection lance is inserted into the blast furnace tuyere through the quick-installation chuck seat of the ball valve, the internal ball is lifted by the lance, and then a quick connection is achieved with the sealing packing on the coal injection lance via the quick-connect chuck. The smooth execution of this series of actions is attributed to our meticulous attention to detail and profound understanding of technology.

       It is particularly worth mentioning that the steel ball and sealing seat of our Type -3 ball valve are detachable, which greatly facilitates daily inspection, replacement, and maintenance. Both the steel ball and the housing can be made from high-quality materials such as carbon steel or stainless steel according to user requirements. This not only ensures the durability of the product but also reflects our deep understanding of user needs and thoughtful service.

       In addition, our company actively engages in research on blast furnace pulverized coal injection equipment. Among these efforts, the invention of an arc-swirl nozzle wheel for blast furnace pulverized coal injection refines the atomization process of the pulverized coal airflow from the lance pipe to the lance tip. Through the design of a spherical pulverized coal atomization disk and the airflow passage gaps, the pulverized coal airflow is ejected in an umbrella shape, forming an atomized pulverized coal stream. These fine coal streams instantly mix with the blast furnace hot air, not only improving the combustion rate of the pulverized coal but also enhancing the mixing ratio of the coal with the hot air.

       As a company that pioneered blast furnace pulverized coal injection technology in China, we have accumulated years of production experience. Xiangye Environmental Protection Company is not only a professional manufacturer of blast furnace pulverized coal products such as dispersion filters and ball valves but also a leader in the industry. We are rigorous in material selection, meticulous in craftsmanship, strict in quality control, and responsible in after-sales service—all to ensure the market competitiveness of our products.

       In addition to product development and production, we also undertake the design and installation of pulverized coal injection systems and pneumatic conveying systems on a long-term basis. Our team possesses extensive experience and profound technical expertise, enabling us to provide comprehensive services to our clients. Whether it is the precision manufacturing of ball valves or the overall design and installation of blast furnace pulverized coal injection systems, we are capable of delivering the most professional and reliable services. At Xiangye Environmental Protection Company, we not only provide products but also solutions. Our goal is to help clients achieve high coal ratios, uniform injection, and low-cost operation, contributing to the green and sustainable development of steel enterprises.
