Maintenance site of DN800 electric ball valve in the waterworks. Recently, the municipal water supply company overhauled the DN800 electric ball valve in the surge shaft of the raw water transmission pipe of Qiujiashan Water Plant, ensuring the water supply without affecting the water pressure and quality.
On April 15, the head office found that the DN800 electric ball valve in the surge shaft of the raw water transmission pipe of Qiujiashan Water Plant had water leakage due to the old equipment during the daily equipment maintenance. According to the on-site survey by the technicians, the electric ball valve could not be repaired and must be replaced. Knowing this, the company immediately ordered the expansion tube and formulated a thorough and detailed maintenance plan. Qiujiashan Water Plant undertakes the main task of water supply in our city. The maintenance of electric ball valve will make Qiujiashan Water Plant unable to operate for a short time. In order to ensure the public's water use, the company decided that Lingfeng Water Plant will undertake the main task of water supply for a short time during the maintenance period.
However, if the main water supply plant is not properly scheduled during conversion, the water quality will fluctuate. Therefore, the company has formulated a comprehensive scheduling plan to ensure that the water quality during maintenance is not affected as much as possible. The maintenance work was completed from the 23rd of the day to 2:00 in the morning. All departments had clear division of labor and tacit cooperation, and successfully completed the entire maintenance process without affecting the water quality and pressure.
