Introduction: Flexible waterproof casing occupies more and more market share for its excellent sealing performance. There are two sealing situations of flexible waterproof casing, which are briefly introduced below. Type a flexible waterproof casing is sealed by rubber ring at one end (rubber ring seal is divided into type I and type II)

flexibility Waterproof casing With excellent sealing performance, it occupies more and more market share. Flexible waterproof casing There are two kinds of airtight situation, the following is a brief introduction.
Type a flexible waterproof casing is sealed with rubber ring at one end (rubber ring seal is divided into type I and type II, type I is composed of two o rubber sealing rings and type II is a conical rubber sealing ring).
Type B flexible waterproof casing (rubber ring seal is divided into type I and type II, type I is composed of two o rubber sealing rings and type II is a conical rubber sealing ring). In addition, a ring retaining ring is welded inside the flexible waterproof casing at the upstream end, and sealing material is added to the retaining ring after the pipeline construction.
The sealing effect of type I rubber seal ring is not as good as that of type II cone rubber seal ring. Type a flexible waterproof casing and type B flexible waterproof casing can achieve tight waterproof effect, but to achieve strict waterproof effect, type B flexible waterproof casing is recommended.
Flexible water-proof casing is used for the pipe crossing the wall. If it is applied to the pool wall, it should also have a good sealing effect. How is the flexible waterproof casing sealed? The sealing of flexible waterproof casing is divided into two sealing methods, one is annular double sealing strip sealing, which is also common. In addition, the conical rubber ring sealing method is more effective than the ring rubber ring sealing, which is mainly used in the office environment with strict waterproof regulations. The 02s404 flexible waterproof casing type II produced by Shanghai Luoying pipeline Manufacturing Co., Ltd. is produced in strict accordance with the standard. The material and specification requirements fully meet the national standard, and the use quality is guaranteed. In recent years, Xinli flexible waterproof casing has been applied in many large projects in China.
Flexible sealing sleeve material
1. The flexible airtight casing is manufactured according to the national standard 04fs02, and the material is q235-a.
2. Flexible filler materials: asphalt hemp fiber, polystyrene board, PVC foam plastic board.
3. Sealing paste: polysulfide sealing paste, polyamide sealing paste.
Flexible waterproof casing (a) and flexible waterproof casing (b) are two types of flexible waterproof casing made of stainless steel plate
Type a flexible waterproof casing shows that:
1. When the upstream surface is corrosive medium, sealing materials can be selected to block the gap.
2. In case of non concrete wall surface at the casing crossing wall, part of the wall should be changed into concrete wall, and the pouring scope should be 200 larger than the wing ring diameter (DS), and the casing must be poured into the wall at one time
3. The thickness of the concrete wall at the pipe crossing shall not be less than 300, or the wall shall be thickened on one side or both sides. The diameter of the thickened part shall be at least DS + 200
4. The net weight of waterproof casing shall be calculated by L = 300. If the wall thickness exceeds 300, it shall be calculated again.
Above are the two sealing forms of flexible waterproof casing. I hope it will help you.
