What is the meaning of dn300 electric butterfly valve wholesale? Shanghai Dongfeng Pump Valve Factory is committed to the production and installation of fire pipeline seismic support and cable bridge. It has rich experience in the industry and is worthy of users' trust. The Ministry of Housing and Urban Rural Development issued the standard "Code for Seismic Design of Building Mechanical and Electrical Engineering" in 2015. The announcement approved the "Code for Seismic Design of Building Mechanical and Electrical Engineering" as the standard, with the number of GB50981-2014, Implemented since August 1, 2015
Before that, all buildings had not considered electromechanical seismic design, so China's construction electromechanical industry had standards in the field of seismic resistance, thus improving the operation of electromechanical systems
According to the Construction Law of the People's Republic of China and the Law of the People's Republic of China on Earthquake Prevention and Disaster Reduction, the policy of "prevention first" is implemented. When the electromechanical engineering facilities such as water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, communication, etc. of buildings after seismic reinforcement encounter an earthquake of local seismic fortification intensity
