If the points for attention in the installation, use and maintenance of the pneumatic ball valve are not completely summarized by the editor, you are welcome to supplement them at any time. Of course, many old customers trust the products provided by Dongfeng Pump Valve very much, so you can pay more attention when you have time.

At high temperature, creep and fracture are the sixth specific key factor of material damage, especially for alloy steel. When the temperature is below 425 ° C for a long time, the carbonized phase in the steel may change to high-purity graphite, while for austenitic stainless steel, only when the elastic modulus exceeds 0.7%, can it be used below 528 ° C. Therefore, when used at high temperature, the main parameters such as compressive strength, creep and high temperature time limit of valve body material shall be measured and calculated respectively. For the design of valve internals, additional consideration shall be given to the tensile strength of materials at high temperature, linear expansion coefficient of auxiliary components, thermal tensile strength difference of guide components, elastic deformation, brittle fracture, etc.
