Background
The flanges are divided into a perforated flange and a non-perforated flange, and threaded holes are not formed in the non-perforated flange, so that the flanges are generally welded when in use. The pipeline is pressed and is checked whether the connection of the water pipe is leaked, flanges are required to be assembled at two ends of the pipeline for plugging in the pipeline pressing implementation step, and the non-hole flange plugging is realized through flange pressing.
At present, when pressure is tested, sealing flange plates are assembled at two ends (welded with PE flange plates) of an external pipeline, two ends of the pipeline are sealed, a silica gel plate is used for sealing in the middle, bolts are used for fastening, and a ball valve is arranged. One end of the pipeline is a water inlet, and the other end is a water outlet. And a pressure gauge is arranged at the water inlet end. And slowly injecting water into the pipeline under the non-pressure state through a pressurizing machine. When water is injected, the exhaust hole should be opened; until the pipeline is full of water, the exhaust hole is closed. The pressure of the pipeline is gradually increased, a pressure gauge can be observed), the pipeline is increased to the test pressure and stabilized for 30min, water can be injected to supplement the pressure if the pressure is reduced, then leakage phenomena are checked at the pipeline interface, the fittings and the like, a blind plate and a sealing ring are required to be installed during common flange pressurizing operation, and the sealing ring is required to be added in the middle because the sealing surface of the flange is hard-sealed.
But the existing flange plugging device has the disadvantages that the manufacturing cost of the sealing ring is high in the use process, the sealing surface is easy to damage, the construction cost is increased, and the use effect of the sealing ring in the large-size flange plugging device is poor, so that the sealing effect is insufficient.
