1. The turbine head shall not be used for lifting, and no auxiliary lever shall be added during operation.
2. The valve shall not be subject to large external force after installation.
3. When the local minimum temperature is lower than 4 ° C, insulation protection should be done; As the end valve, it should be heated with a pipe or jacket to prevent the temperature of the pipe wall from falling below 0℃.
4. It is strictly prohibited to install and use in the pipeline under vibration or rapid changes in medium temperature.
5. The operating conditions shall be consistent with the requirements in the performance specifications.
1. Structure size conforms to GB/T12221, small size, light weight, easy to operate.
2.90 ° operation opens quickly; The plate has high strength, large flow area, small flow resistance and energy saving.
3. The medium can flow from both sides of the flange disc valve in any direction, which can achieve the purpose of connecting or cutting off.
4. The operation torque is small, labor saving and lightweight.
5. The number of opening and closing experiments is more than ten thousand times, with a long life.
6. Complete sealing is achieved, and the gas leakage is zero.
