Precautions for the installation of flexible waterproof casing
We have a lot of detailed introductions. Whether it is used in fire protection or in swimming pools, there are corresponding detailed installation introductions. The contribution of waterproof casings to our daily life includes various environments. The water supply pipeline plays an indispensable role and has become an important part of the engineering construction. Then the installation of this product at the water inlet of the water pump. Today, the technician of Yucheng Water Supply Equipment Co., Ltd. will give you a brief introduction. The first and most important point is that it must be carried out in accordance with the standard installation specifications. The end with the bolt pressure plate needs to face the wall. On the outside, keep the bottom end of the product level with the inside of the wall.
The flexible waterproof casing is indirectly connected to the water pump port. The two need to be separated by a valve shock absorber unit. The steel pipes worn should be placed in a balanced manner to ensure that the pressure plate squeezes the rubber sealing ring so that it can be evenly sealed to prevent water leakage. Because the water flow pressure at the water pump mouth is too high, supports and hangers should be installed at the casing to reduce the burden on the casing working room.
The material used for flexible waterproof casing is carbon steel under normal circumstances. In addition, stainless steel needs to be used under special circumstances. Due to the different properties of different materials, the price difference is also relatively large. Waterproof casings made of stainless steel are high-end. Carbon steel flexible waterproof casing has a favorable price and is widely used. It is the most commonly used type by customers. The material is stainless steel flexible waterproof casing, which has very good anti-corrosion, acid and alkali resistance, and is more suitable for chemical pipelines and refilling pools. Pipes that have certain requirements for anti-corrosion. The cost of stainless steel flexible waterproof casing is relatively high due to the high price of the material, and the corresponding demand is very small. Although its performance far exceeds that of carbon steel waterproof casing and stainless steel waterproof casing, it is still rarely used. , most customers cannot accept its price.
