  • The role of valves in urban water supply

    Valves play a very important role in urban water supply systems. Generally speaking, valves are used to control the direction, speed and pressure of water flow to ensure that water can flow smoothly to various areas and buildings in the city. Valves can also be used to close or open pipes, maintain and repair water pipes, adjust water pressure, and respond to emergencies (such as leaks or pipe ruptures).

  • The Origin of the Butterfly Valve's Name

  • Ductile iron pipe: A powerful "blood vessel" for the city's underground

    ​Every time you turn on the faucet, have you ever wondered how the tap water travels through the entire city to your home? This is inseparable from a key material - ductile iron pipe. This pipe, which is widely used in municipal engineering, protects the "lifeline" of urban water supply with its excellent performance.

  • What is GT Type Ductile Iron Pipe?

    The sealing principle of the GT type interface of GT type ductile iron pipe is similar to that of the T type interface. As the internal pressure of the pipeline increases, the tighter the contact surface between the rubber ring sealing sleeve and the socket, the better the sealing effect.

  • Why do gate valves always leak?

    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.
