1, first of all, the air bag inflator accessories used for pipeline water blocking are combined to check the leakage of tools. Put the airbag in a bucket full of water and hold it. Inflate the air bag with a cylinder. The air pressure should not exceed 0.02MPa (0.015MPa-0.02MPa easily). Check the airbag for leaks.

2. Open the pipe inspection port, slowly lower the tube plug air bag from the mouth to the desired position, and then inflate the water plug air bag to the appropriate pressure is good. Note that the riser fittings should avoid blocking the airbag.

The reasons are: (1) There are joints in the inner wall of the area, which affect the tightness of water plugging;

(2) In order to prevent the water blocking bag from expanding to one side, the air pressure will not rise, and if it is inflated, the water blocking bag will burst. For cast iron drainage pipes, it is necessary to clean the sand, the inner wall is smooth, and no burrs are allowed, otherwise it will affect the sealing of the water seal and even Pierce the capsule. Various specifications of water blocking air bags must be used in the corresponding pipeline, can not be large.

Hebei Samai Technology Co., Ltd. mainly produces sewage water blocking air bags, pipeline blocking air bags, high pressure air bags, repair air bags and disembark air bags and Marine guard strings and other rubber products. The sealing area of the product can reach 100%, the sealing ability is good, and the operation is simple and convenient. Our factory is committed to the research and development of all kinds of industrial air bag products, products are widely used in construction, pipeline drainage engineering, municipal engineering, mining, port, chemical industry, water supply, machinery, military and many other fields and have made achievements. Products are sold to major provinces and cities in China as well as export trade at home and abroad. Welcome the majority of enterprises, users and consumers to contact us, we will be in line with the use of good products, to provide users with good service for the purpose, dedicated to serve you!
