ball valve

    Our Xiangye Environmental Protection Company has profound and long-standing production experience in the field of pulverized coal injection technology, especially in blast furnace pulverized coal injection technology, which has already become our technical feature. The ball valve series we develop and produce, whether national standard or non-standard, fully demonstrate our technical strength and product quality.
Our Ball Valve, Liaocheng Spray Gun Check Valve features ingenious design, compact structure, excellent air tightness, extremely strong pressure resistance, low failure rate and economic practicality. This type of valve is designed to provide stable and reliable guarantee for the connection between the blast furnace straight blowpipe and the pulverized coal lance during the blast furnace pulverized coal injection process. When the pulverized coal lance penetrates into the blast furnace, the ball valve opens to allow pulverized coal to be injected smoothly; when the pulverized coal lance needs to be withdrawn from the blast furnace, the ball inside the ball valve will automatically close under the combined action of the pressure in the blast furnace and its own gravity, effectively controlling the overflow of hot gas in the furnace.

    Among various ball valves, the jujube-core-shaped ball valve and the square ball valve are the most common, and they are widely used in the blast furnace pulverized coal injection systems of domestic iron and steel enterprises. The internal structures of these two types of ball valves are both elaborately designed, which are not only easy to install and disassemble, but also convenient for inspection, replacement and maintenance. Among them, the steel ball and sealing seat of the -3 type ball valve can be disassembled and inspected according to the user's needs.

    In addition, we not only focus on the R & D and production of ball valves, but also commit to the innovation of blast furnace pulverized coal injection equipment. Among them, the arc swirl spray wheel for blast furnace pulverized coal injection that we specially developed has a unique technical solution. The spray wheel is composed of a pulverized coal pipe and a lance head, and the top of the lance head is equipped with a unique spherical pulverized coal atomizing disc. A cleverly designed gap for pulverized coal airflow circulation is set between the atomizing disc and the end of the lance pipe, so that the pulverized coal airflow can be shunted through the atomizing disc and ejected in an umbrella shape, forming an atomized pulverized coal flow.

  
    This design enables the fine atomized pulverized coal flow to mix with the hot blast of the blast furnace instantly, achieving good combustion effect, thereby improving the combustion rate of pulverized coal and the mixing ratio of pulverized coal and blast furnace hot blast. Our products not only have reasonable structure and convenient use, but also can significantly improve the utilization efficiency of coal, making important contributions to energy conservation, emission reduction and green production of iron and steel enterprises.
    In general, the technological innovation and product quality of our Xiangye Environmental Protection Company in the field of blast furnace pulverized coal injection have been widely recognized in the industry. We firmly believe that only through continuous technological innovation and product upgrading can we meet the needs of customers and make greater contributions to the sustainable development of iron and steel enterprises.
