What is the meaning of electric butterfly valve DN400 wholesale? Dongfeng electric butterfly valve professional consumer manufacturers have short supply cycle and guaranteed quality
The proficiency of construction personnel in the operation of electric butterfly valves will also affect the service life. There must be differences between a worker who often uses plugging and a worker who has never used plugging.
It doesn't matter if it hasn't been used. Just follow the normal operation of our instruction book and there will be no problem. Stop inflating according to the rated pressure of our rules. Never use it under overpressure, and there will be any problem when it is used. Put the water blocking into the pipe mouth that needs to be blocked. The length of the pipe put in is the length of the water blocking. Stop inflating through the air inlet valve. When the pressure reaches a certain value, the construction can be started. After the construction is completed, turn over the air inlet valve to vent, so that the water blocking project is completed. The working principle of pipe water plugging is to use high-quality pipe water plugging to shrink through inflation. When the gas pressure in the water plugging reaches the rule request, the water plugging fills the entire pipe section, and the water leakage is blocked by the friction between the pipe water plugging wall and the pipe, so as to reach the goal of no water seepage in the target pipe section. The pipeline shall be blocked completely and sent into the pipeline. If personnel are required to go down for operation, flanges must be installed to ensure the safety of personnel. Connect the end of the gas nozzle blocked by the pipeline with pipes, pressure gauges, air pumps and other inflation tools, and then inflate according to the scale on the pressure gauge. During inflation, if the pipe is blocked and contracted to one side, the air pressure will not rise. At this time, if the inflation continues, it will explode. At this time, check whether the sludge in the pipeline can be cleared and cleaned. The inner wall must be flat, and there should be no burr, otherwise it will be punctured.
