Inflatable Rubber Water Stopper

We offered Inflatable Rubber Water Stopper for testing of the South Africa World Cup stadiums in 2010, and won the praise of the customers.Working principle of Inflatable Rubber Water Stopper:
The Inflatable Water Stopper is made of high quality rubber sealing gasbag, and the Inflatable Rubber Water Stopper will be expanded by filling with compressed air, when the gas pressure of sealing gasbag reach formulary requirement, the Inflatable Rubber Water Stopper will fill in the whole pipeline section, and blocks the leaking because of the friction, thus achieved the goal without ooze water in pipe.
Usage method of Water Stopper:
Before operation of pipeline work of flow condition, measure the diameter of the sealing pipe; Hold on the side of the Inflatable Rubber Water Stopper with air cock, slowly put the Inflatable Rubber Water Stopper into pipes. Before inflate the Inflatable Rubber Water Stopper, insert it completely in pipe, and connect the barometer and pump, then opened slowly the valve of pressure control table. The air pressure is controlled in safety area outside of pressure marked red. Taut drawing rope in sleepers on rope binding firm, through pressure control list, observation data, while it reaches the formulary requirement, close the vales of pressure control, and inflating is end.
