High-pressure deep-water gates are hydraulic control devices used in high-head pressure environments, primarily in fields such as water conservancy and hydropower, municipal construction, and water supply and drainage. Their core structure and functional characteristics are as follows:
Core Structure
?Gate Body?: Composed of an arc-shaped panel and primary and secondary beam grids, made of zinc-sprayed steel plates or cast iron, with copper or stainless steel corrosion-resistant materials embedded in the sealing surface. ?
Embedded Components?: Include side sealing seats, bottom sills, and support hinge seats, with a sealing system using P-type rubber sealing elements. ?
Transmission System?: Used in conjunction with hoisting machinery, driven by mechanisms such as gears and worm gears to raise and lower the gate. ?
Performance Parameters
?Head Withstanding Capacity?: Forward design head can reach 50 meters, reverse pressure resistance 20 meters, with a sealing index of ≤1L/h·m. ?
Sealing Design?: Bidirectional sealing structure, with the top of the guide rail higher than the centerline of the gate body to prevent displacement of high-pressure water flow from affecting sealing performance.
