Imported pneumatic valve (Pneumatic valve) is the use of compressed air energy, driven pneumatic gear, so as to open the valve to close or adjust the valve opening of the valve, including pneumatic devices and valve body. Imported pneumatic devices (pneumatic actuators) are divided into single-acting and double-acting, pneumatic actuators are generally required with pneumatic parts (air filters, pressure reducing valves, oil mist), according to the need to select the limit switches and positioners. Imports of pneumatic valve actuator disc, fork and connecting pin and other components are made of alloy steel, more wear-resistant, and the joints are made of special materials, bushings, metal-free contacts, the number of life switch Up to 1 million times or more. And after running air consumption is small, so the initial and operating costs have advantages. Fast response, the fastest switch response time can be 3 seconds.
Refractory clay bricks use hard clay clinker, soft clay as the main raw material, according to certain particle size requirements for the ingredients, after molding, drying, firing at a high temperature of 1300 ~ 1400 ℃. Clay brick belongs to the weak acid refractory products, can resist the erosion of acidic slag and acidic gases, the resistance to alkaline substances is slightly worse. Clay bricks have good thermal properties and are resistant to rapid cooling and heating.
