What are the fittings used in the water supply pipeline?

Urban underground pipelines are not only diverse, but also have complex structures, and furthermore, different types of underground pipelines have different embedding characteristics. As an underground pipeline detection worker, it is necessary to learn the basic knowledge of underground pipelines, master the structural characteristics and embedding rules of different types of pipelines, who is in the position to adopt detection technology methods corresponding to pipelines to achieve high-efficiency and high-quality Underground pipeline detection mission. Therefore, today we will discuss the structure of the water supply pipeline and its fittings.

Characteristics of Water Supply Pipelines

The construction of the water supply pipeline system generally starts from the water source. The water in the water source is sent to the water plant through the main pipeline. After the water plant is purified, it is then sent to the water area by the main pipeline, such as factories, residential areas and enterprises. According to their own needs and conditions, each water district lays out the water supply pipeline system of the district, and sends water to each water point through the system or to each household water point through branch pipes.

The layout of the factory and campus water supply pipelines is determined according to the process flow to construct the layout of the buildings and the terrain conditions of the site, which is generally divided into three systems, namely, grouping system, combined system and mixed system. The system for separating production water, domestic water or fire water is called a grouping system. Domestic water and fir water being combined into one system and production water being combined into an independent system is called a combined system. The production water, domestic water and fire water being combined in a system is called a hybrid system.

The urban water supply network usually adopts a combined system containing domestic water and fire water. Some urban domestic water and fire water are gradually separated to form separate systems. In addition, some cities have renovated the pipeline network and established a reclaimed water system, which is mainly used for greening, firefighting and sanitary equipment.

Pipe Fittings for Water Supply Pipelines

Pipe fittings are devices installed on pipes and equipment, which are used for opening and closing and adjustment. It is generally divided into two categories: water distribution fittings and control fittings. Water distribution pipe fittings, for example, various water nozzles installed in sanitary appliances and water points, used to regulate and distribute water flow. Control fittings are used to adjust water volume, water pressure, judge water flow, and change the direction of water flow, such as gate valves, check valves, and float valves.

In residential and public buildings, there are three or more branch water distribution points connected from the riser, but at the same time, no more than six closed water distribution points. The process requires the production equipment to be equipped with water distribution branch pipes or water distribution pipe sections. The most commonly used water supply pipe fittings are: T-shaped pipe, fork pipe, cross pipe, elbow pipe and so on.

Understanding the importance of pipe fittings can help underground pipeline detection workers better grasp the basic knowledge of underground pipelines.
