Eccentric hemisphere valve , which shall be reinstalled after cleaning;
3. Generally, the purging pressure shall not exceed the working pressure of the pipeline system, and shall not be less than 25% of the working pressure. Large pipelines shall not be less than 0.6 mpa;
4. The medium used for purging shall be selected according to the design requirements or the use and construction conditions of valves and pipes;
5. During purging, except for non-ferrous metal and non-metallic pipes, the pipe wall should be hammered (stainless steel pipes should use a wooden hammer to dynamically balance the electric regulating valve), especially for welds, dead corners and pipe bottom parts, but the pipes should not be damaged;
