Water blocking airbag/water blocking airbag/water blocking manufacturer model price pipeline water blocking airbag is also called pipeline blocking airbag, water blocking airbag. Pipe sealing airbags are made of reinforced natural rubber. Each pipe sealing airbag will be tested at . In order to ensure the strength of the pipe sealing air bag structure, we adopt a safety factor three times the rated working pressure of the pipe sealer. The working principle of water blocking is to use a pipe sealing airbag made of high-quality rubber to expand it by inflating it. When the gas pressure in the water blocking airbag reaches the specified requirements, the water blocking airbag fills the entire pipeline section, and the pipe sealing airbag is used. The friction between the wall and the pipe blocks water leakage, thereby achieving the goal of no water seepage in the target pipe section. The manufacturer supplies rubber sealing airbags for water blocking. Some preparations before the operation of virtue quality water sealing and plugging are as follows: Understand the flow conditions of the working pipe section, the source of the upstream water flow and the distribution of the pipe network, the sources and water flow conditions of each branch pipeline, and the working port. Size, coordinate and discuss with the pipeline dispatching department, and schedule plans for water outage, water blockage, and water diversion. Including water diversion plan, water pressure control of relevant pump stations, and branch pipe blocking methods. Use the equipment list, formulate safety protection measures, make corresponding steel flange tees according to the pipe diameter of the construction pipe section (the purpose of the tee is to seal the outlet of the air bag after the construction is completed), and prepare flange blanking plates of corresponding diameters. , the manufacturer supplies rubber sealing airbags, water-blocking airbags, virtue-quality Hebei water-closing test airbags. Since we purchased a pipe sealing airbag with a diversion hole and a pipe sealing airbag without a diversion hole, we used a pipe sealing airbag without a diversion hole. The second test was carried out in a pipe section with a larger diameter, and a pipe with a diversion hole was used to seal the air bag. The staff wear protective masks and safety equipment, and are monitored by dedicated personnel on the ground. They measure the diameter of the pipe into which the blocking air bag enters to ensure that the size is within the range of use of the blocking air bag. Before inserting the pipe blocking air bag, clean the outside of the blocking air bag and the sealing air bag. Inside the pipe where the airbag is about to enter, pull one end of the airbag (the end with the air nozzle) with a traction rope, and slowly put the airbag into the pipe. Pay attention to the mouth of the pipe during the insertion process to avoid damaging the waterbag. .
