Due to the leakage and damage of pipes in long-term use, timely repair must be carried out. In the new town residential area, the underground drainage system must be closed water test, in the past, the old method of brick, cement and yellow sand head is used, and this method is too wasteful of materials and artificial, especially poor work efficiency. Pipeline plugging airbags particularly suitable for the drainage pipeline plugging, gas test, closed water test, leakage and maintenance test. "Municipal pipeline plugging bag" the call method or the use of different geographical areas, such as: inflatable pipeline occluder, pipeline plugging and water plugging, pipeline plugging airbags, airbag, airbag pipeline pipeline plugging ball, etc.. In order to quickly check the drainage pipe leakage, we developed a rapid and simple construction tools - pipeline plugging air bag, the airbag has good elasticity, high strength and pipe wall tightly, simple operation, time-saving and labor-saving and convenient, is a closed water drainage pipeline construction tools, full water test sewage pipeline plugging and emergency repair ideal, since the product from the market in recent years for its excellent quality by many domestic large-scale construction units and the construction units of praise and favor.

Compared with the first generation pipeline airbag, this tool has the advantages of good air tightness, flexibility, high wear resistance, high acid resistance, anti-aging, cheaper price, better quality, more perfect function, more intuitive detection and so on,. The production pipeline gasbag is easy to operate and the inspection is intuitive. It can timely check and eliminate the quality hidden trouble in the construction process.

Usage method:

Open the pipe inspection port, the closed water blocking (pipeline airbag) from the check port slowly placed the required location, and then to the closed water plugging (pipeline airbag) inflatable, inflated to the appropriate pressure is good. Attention should be paid to avoid the pipe fittings, because: (1) there is a joint in the wall, which affects the tightness of water shutoff. (2) so as not to expand to the side, the air pressure can not hit, if continue to inflate, will be broken. For cast iron drainage pipe, clean sand is required,The inner wall is smooth and no burrs are allowed,Otherwise, it will affect the sealing of water plugging and even pierce the capsule. All kinds of closed water plugging (pipe air bag) must be used in the corresponding pipe,You can't take small generations. After checking, release the gas from the air bag and stop the water from the pipe

3,Get ready:Firstly, the components of the air bag inflatable device are combined,Tool leak check.Hold the water bag in the bucket full of water and hold it down,Inflating the air bag with water pump by air pump,Check if the air bag is leaking.

4,Open the standpipe inspection port,Place the water tight airbag downwards from the mouth to the desired position,Then inflate the gas bag,Make the water tight gasbag close to the inner wall of the pipe, and the water is not leaking.Be careful,Water plugging airbag should be avoided at the riser pipe fittings,Reason:,1There is a joint on the inner wall,Influence on tightness of water shutoff.2So as to prevent the airbag from expanding,The air pressure can't beat up,If you continue to inflate,Water plugging air bag will be broken.Cast iron drain pipe,Sand cleaning is required,Inner wall leveling,Burr is not allowed,Otherwise, it will affect the sealing performance of water shutoff,And even pierce the capsule.All kinds of water proof air bags must be used in the corresponding pipes,You can't take small generations.

5,Irrigation at the floor (also at the entrance) to the floor height,Then the irrigation pipe and pipe interface are checked one by one,If there is a leak,Make a mark,After drainage, repair treatment,Such as rubber ring flexible interface,It can be repaired with water tight bolt at leakage interface.If there is no leak point in the irrigation pipe inspection,Then the water level is stable,Irrigation duration15Minute,keep5The water level is not reduced to qualified for minutes.

6,Deflate the airbag,And then slowly squeeze out the air bag,Be careful not to damage the airbag.

7,Take out the blocked air bag,The water should be discharged quickly,If it drops very slowly,It shows that there is debris blockage in the irrigation pipe section,It should be cleaned up in time.

8,Method of inflating air bag with water blocking,It can also check whether the stool is leaking.The water blocking air bag is arranged at the drainage port of the squatting stool and is inflated,Then irrigation in the squatting stool (upper edge of the water closet),If the water level drops,It indicates that there is leakage at the flushing water inlet interface,Or the water interface of squat stool is not sealed tightly,Or there's a leak in the squat stool itself,Should be directed against.

9,The irrigation test should be carried out in different sections (layers),The test results should be recorded.

10,The irrigation test methods of buried pipeline are basically the same.

11,This water bag is a national patent product,The made.
