The self-anchored ductile iron pipe adopts a special mechanical design to weld the ring to the socket end to achieve reliable anchoring performance, while retaining the flexibility of the joint, with good flexural performance, which can replace the function of the constraint block and realize the design without constraint blocks.

Hydraulic control valves are automated valves that precisely regulate fluid dynamics through hydraulic actuation. These valves operate on the principle of using liquid pressure (typically water or oil) to drive an actuator, which controls spool displacement to adjust flow rate, pressure, or direction of the medium within a pipeline. Integrating a pilot control mechanism, main valve body, and hydraulic circuit, hydraulic control valves feature self-feedback and dynamic response capabilities. These valves perform remote/automated fluid management in complex systems, serving as critical control components in industrial automation.

The selection of urban water supply pipelines usually depends on the following factors: Material: Commonly used water supply pipeline materials include steel pipes, cast iron pipes, plastic pipes (such as PVC, PE, PPR), etc. Different materials have different characteristics, such as durability, corrosion resistance, and scope of application.

The core sealing of a gate valve relies on the tight fit between its wedge or parallel disc and the valve seats. In theory, when the disc is fully lowered, it should block the fluid passage. However, in practice, solid particles in the fluid (such as sediment, welding slag, or scale) can easily become trapped between the disc and the seat sealing surfaces. Even very small particles can prevent the disc from fully seating, leaving microscopic gaps on the sealing surface and causing leakage. This phenomenon is particularly common in pipelines with unclean fluids.

Carbon steel pipe is an extensively used industrial piping material. Its core components are iron (Fe) and carbon (C), with carbon content typically ranging between 0.05% and 2.0% – the critical factor determining its mechanical properties.

The following points need to be considered when selecting a water meter: Measurement requirements: Select the appropriate water meter type according to the flow rate and accuracy requirements to be measured. Installation environment: Consider the environment in which the water meter is installed, such as whether special
