Municipal water supply system
In the criss-crossing municipal water supply network, cast iron gate valves build a main pipeline barrier with excellent corrosion resistance to resist the erosion of groundwater and disinfectants. Its fully open and fully closed design ensures direct transmission and distribution from the water source to the water plant; while the butterfly valves of the branch pipeline network reduce pressure loss by more than 30% with the streamlined valve body, and realize remote pressure regulation in the control room through worm gear transmission. The two work together to build a constant pressure water supply network from the "aorta" to the "capillaries", ensuring stable water flow from the taps of millions of households.
Petrochemical refining process
Facing high temperature, high pressure, flammable and explosive refining scenes, the high-pressure ball valve adopts a metal hard seal structure, which can still maintain zero leakage under a pressure of 1500psi. Its 90° fast opening and closing characteristics can gain golden processing time for emergency conditions; the stop valve uses a replaceable valve seat design to achieve ±0.2% flow accuracy control in the catalyst injection link, and cooperates with the intelligent positioning system to compensate for the influence of thermal expansion. This pair of "safety guards" ensures the parameter stability and intrinsic safety of core processes such as crude oil catalytic cracking.
Cogeneration steam pipeline network
In a 450℃ high-temperature steam environment, the three-eccentric butterfly valve resists thermal stress deformation through a multi-layer graphite sealing structure. Its remote electric actuator adjusts the opening in real time according to the steam enthalpy value to optimize the energy cascade utilization; the check valve adopts a double-flap spring design, which is synchronously closed at the moment of turbine shutdown. Its 0.5-second response speed effectively prevents blade erosion caused by condensate backflow. This pair of "regulation guards" increases steam thermal efficiency by 8% and reduces equipment maintenance costs by 40%.
Fire sprinkler system
When the fire triggers the sprinkler system, the open stem structure of the groove gate valve directly displays the opening and closing status, and its hydraulic drive device ensures that the nominal flow rate is reached within 3 seconds, forming a three-dimensional water curtain coverage; the wet alarm check valve converts the water flow signal into an electrical signal, and synchronously starts the fire pump through the pressure switch and links the alarm host. Its modular design supports NFC inspection and remote testing. This "smart sentinel" combination increases the success rate of extinguishing initial fires by 65%, building a double line of defense for the safety of life and property.
