It belongs to the civil air defense ventilation system software and plays an important role in civil air defense engineering. It mainly protects some ventilation pipes. It has four ventilation modes: isolated ventilation, peacetime clean ventilation, wartime poison filtering ventilation and wartime clean ventilation. The following people on the "civil air defense sealed casing performance characteristics and the differences between other types" to understand in detail.
As an important pipeline in civil air defense engineering, ventilation pipe also plays an important role in civil air defense engineering. Like the conventional water supply and drainage pipeline, the ventilation pipe also needs to install corresponding air defense ventilation sealed sleeve products in the normal civil air defense project, so as to carry out reasonable protection for the ventilation pipeline. The pipeline is a professional manufacturer specializing in the production of civil air defense sealing sleeve
Key production of a variety of water supply and drainage civil air defense sealed sleeve and ventilation closed sleeve, can consider a variety of water supply and sewage pipe and ventilation pipe use demand, in which civil air defense ventilation closed sleeve product, as our company's main product, our enterprise has technical energy in its production and manufacturing industry to ensure the quality of products. The civil air defense airtight ventilation sleeve products manufactured by our company refer to the standard atlas of civil air defense engineering construction in various provinces, summarize the requirements and key points in the standard compilation of each province, and integrate the production and use status in most areas of China;
On this basis, we develop and manufacture new products, which can To meet the construction and use needs of various high-standard civil air defense ventilation engineering projects, our enterprise can provide on-site ventilation duct solutions for customers, supply of additional products, and specific guidance for installation and maintenance in the middle and later stages according to the basic construction and use characteristics of on-site engineering projects Small manufacturers do not have professional skills, so our products have been used in a variety of large civil air defense projects.
   Waterproof casing There are many types of Flexible waterproof casing And civil air defense sealed casing is common, the two products are mainly used in different areas, flexible waterproof casing into the pipeline across the wall
Structures subject to vibration or strict waterproof requirements. The position of civil air defense airtight casing to pass through civil air defense area. Flexible connection is used between flexible waterproof casing and pipeline, and rigid connection is selected for civil air defense sealing sleeve.
The structure of civil air defense airtight casing is similar to that of flexible waterproof casing, but only less than that of flexible waterproof casing Rigid waterproof casing There are more wing rings on the outside and a baffle plate to prevent shock wave. The baffle plate is directly welded with wing ring and pipeline. If the civil air defense airtight casing is set between two personal defense areas, wing ring and shock wave baffle must be set on both sides of civil air defense closed sleeve.
The waterproof sleeve is generally applicable to the structures with vibration or tight waterproof requirements where the pipeline crosses the wall, while the steel waterproof sleeve is generally applicable to the structures where the pipeline passes through the wall and requires general waterproof.
