The installation size of the embedded parts/electric ball valve on the upstream surface and the service life of the wall of the structure must be equipped with embedded parts if there are pipes passing through it. This requires the use of electric ball valve series products. According to the construction requirements and wall types, including the tightness of the waterproof requirements, different types of products are selected. Generally, manufacturers only provide embedded parts through the wall, and the through wall pipeline needs to be purchased by the construction unit. The outer diameter of the pipeline must match the inner diameter of the casing before it can be used. Of course, these should be implemented according to the relevant national atlas. Take 02S404 national standard flexible electric ball valve as an example, usually according to the provisions of the atlas, For example, for DN100, the size of the conventional type is that the inner diameter of the casing pipe is 146mm, the inner diameter of the gland is 114mm, and the outer diameter of the pipe is 108mm. The pipe can just pass through. This size is matched according to the national atlas standards. It also belongs to the actual diameter pipe threading operation, and there are a lot of enlarged openings. Strictly speaking, it is a special type, which is applicable to the project with very strict requirements. In addition, after the pipeline medium is dredged in the later stage, there will be greater pressure in the pipe, so it is necessary to use the pipes with thicker pipe walls for construction, or DN100:
The inner diameter of the casing pipe remains 146mm, and the gland needs to be processed separately by the lathe. The inner diameter needs to be processed to 133mm, which is suitable for the pipe with an outer diameter of 114mm. In order to improve the service life of the electric ball valve, Shanghai Dongfeng Valve Co., Ltd. suggests that if it is not specially required, it should be painted for anti-corrosion treatment. It is not only beautiful, but also has a long service life. The importance of anti-corrosion paint lies in that after our manufacturer has produced the electric ball valve series products, in order to facilitate the customer's on-site use and avoid installation errors, they will spray anti-corrosion paint on the inner and outer walls of the whole evenly, and then spray the model on the casing. Therefore, the corrosion of pipeline is also related to the service life of electric ball valve. Therefore, painting and anti-corrosion treatment are also crucial. The electric ball valves produced by Hengchang Pipeline are produced in strict accordance with the national production standards. When selecting the electric ball valves, different types of products should be selected according to the construction requirements and wall types, including the tightness of the waterproof requirements. In order to improve the service life of the electric ball valve, it is necessary to paint it for anti-corrosion treatment. It is not only beautiful, but also has a long service life.
