As the process of valve manufacturing is one of the important contents of product design, the process of valve manufacturing must put forward a requirement for the process of valve design

Recently, China Machinery Industry Federation and China General Machinery Industry Association, entrusted by the state energy administration, hosted the "appraisal meeting for key valves of large diameter natural gas pressure regulating device and new products of compressor anti surge valve" in Tianjin. The valve is the key valve of the pressure regulating device with the highest pressure and the largest diameter in China.

In the process of using the valve, there are often some troubling problems, such as the valve is not closed tightly, how to do
