Hard sealed high temperature and high pressure ball valve What are the characteristics? The hard-sealed high-temperature and high-pressure ball valve is first hard-sealed and sealed with Stirling Carbide. Good sealing performance, long life, and wear resistance, the important is high temperature and high pressure. Second, the material of the ball valve is also very important. General hard-sealed high temperature and pressure ball valves are mostly made of stainless steel or chrome molybdenum steel. The use of carbon steel material temperature is less than 425 degrees. Therefore, if you want high temperature, you must use the above two materials. After high pressure. General high-pressure ball valves use forged steel. Because the forged steel material has good airtightness and no air hole. Can withstand high pressure. How does an industrial fan achieve cooling and ventilation? Through the rotation of huge fan blades, a large amount of airflow is pushed to the ground, forming a certain height of airflow layer horizontal movement on the ground, thereby promoting overall air circulation, which can achieve all-round ground coverage and air three-dimensional circulation. The industrial large fan adopts aerodynamic principles and advanced technology to manufacture streamlined fan blades, which require low power for operation and can generate a large area of natural breeze system, thereby playing a role in cooling and ventilation.
