Shengli valve: Shenzhen North line safety hazard rectification project report

Guangdong Shenzhen North line water diversion project safety hazard rectification (including Longxi water supply reconstruction) project crosses Longhua District and Longgang District. The total length of the project line is 19.46 kilometers, and the reconstruction pipe length is about 7.6 kilometers. It is divided into 11 construction sections, which is related to the water use of 4.5 million people in Shenzhen. On July 12, 2020, Shenzhen North line safety hazard rectification project trial water

Guangdong Shenzhen North line diversion project safety hazard rectification (including LongQian water supply reconstruction) project crosses Longhua District and Longgang District. The total length of the project line is 19.46 kilometers, and the reconstruction pipe length is about 7.6 kilometers. It is divided into 11 construction sections, which is related to the water use of 4.5 million people in Shenzhen. On July 12, 2020, the test instrument of Shenzhen North line safety hazard rectification project was digitally displayed and can automatically print the test results and data, and the treated water was successful

the general contractor of the project: Sinohydro Bureau 7 Co., Ltd. Our company provides electric double eccentric soft sealing butterfly valve dn2200 dn2800 d942x-10q, double flange force transmission joint dn2200 2800 vssjaf-10c, double flange limit expansion joint dn3400 vssja-10c, composite exhaust valve carx-10q dn400, pipeline sludge discharge valve z45x-10q dn400, fast in and slow out exhaust valve fgp4x-10c dn400 and other valves for this project

participated in the reconstruction project of Shenzhen Shangpu pump station pump room. Five fast in and slow out exhaust valves fgp4x-10c dn400 of our company are installed at the pump outlet of the pump station. The exhaust valve has the function of three-stage slow closing waterproof hammer. The fast in and slow out function of the exhaust valve meets the hydraulic calculation of Wuhan University for the pump station and pipeline, improves the water delivery efficiency of the pipeline, eliminates destructive water hammer, and protects the water delivery safety of the pump and pipeline. The fast in and slow out exhaust valve provided to the pump station can realize full speed exhaust in case of low pressure difference, and limit the exhaust speed in case of high pressure difference. It has three-stage exhaust and suction functions. The destructive water hammer of the pipeline medium is eliminated, and the impact of the pressure fluctuation of the pipeline medium on the pipeline system is effectively prevented because people all over Asia prefer to use wax and other products for quick exhaust

in the safety hazard rectification project of Shenzhen North line, dn3400 PN10 800m steel pipes are arranged in the open air. A double flange limit expansion joint dn3400 vssja-10c is installed in the middle of every 200m of steel pipes, and the total number of double flange limit expansion joints installed is 3. The temperature in Shenzhen is high in summer, and the thermal expansion and cold contraction of large-diameter steel pipes are relatively large. The expansion and contraction of our double flange limit expansion joint can meet the thermal expansion and cold contraction of 800 meter steel pipes to ensure the normal water delivery of the pipes
