1. Applicable media: Sewage, seawater, and clean water concealed cast iron copper inlaid gate is mainly composed of gate seat, gate plate, copper inlaid seal, adjusting wedge block, and lifting part. Its structural design is reasonable, with good sealing performance, strong corrosion resistance, long service life, easy installation, and convenient opening and closing. Its structural types include square, rectangular, circular, and can be manually or electrically operated. The guide rail can be symmetrically arranged on both sides of the door frame and connected to the two ends of the door frame with stainless steel bolt positioning pins (for small and medium-sized gates, the guide rail can be poured into one with the door frame). The length of the guide rail is generally 1/2 to 1/3 of the full opening height of the gate, so the overall structural strength is high, rigidity is high, wear resistance, corrosion resistance is good, and pressure bearing capacity is large.
2. It is installed using pre embedded steel plates or pre embedded bolts, which is easy to install, debug, use, and maintain, and has a long service life.

3. The sealing is achieved through the wedging of the wedge block device, and the sealing material is copper alloy or rubber, which is finely processed and matched, resulting in good sealing performance.

4. Complete variety specifications and wide adaptability.

5. Used in conjunction with a hoist, the gate is the working part, and the hoist is the executing part for opening and closing the gate. The hoist is driven by human, electric, pneumatic, hydraulic mechanisms to drive the gears, worm gears, and other components of the transmission device. The drive nut or screw rotates to make the gate shaft move vertically up and down, thereby opening or closing the gate to achieve the purpose of water flow, water closure, or water level adjustment.

3 Main technical performance parameters: 1. Model and specifications:

Clear pole ZMYDN200~DN2500mm

2. Main performance indicators: a) The clearance between the sealing surface of the gate should be ≤ 0.1mm, and the thickness of the sealing seat should be greater than 10mm. b) Sealing surface water leakage per meter length: forward ≤ 0.7L/min · m, reverse ≤ 1.25L/min · mc) nominal pressure ≤ 0.1Mpa; The sealing test pressure is 0.1Mpa. d) Working environment: temperature -20 ℃~120 ℃, humidity: 95%, working medium: water and sewage, pH value: 5-10e. Installation position: normally facing water and in a vertical position. f) The maximum working head: unidirectional compression: forward: 10m, reverse: 5m, bidirectional compression: both are 10mg) opening and closing speed: not less than 0.2m/min, not more than 1.5m/min. h) The distance between the gate frame and the side wall is ≥ 300mm, and the distance from the bottom of the pool is ≥ 150mm to 250mm.

Product application: Widely used in urban water supply and drainage, metallurgy, petroleum, chemical, irrigation, power, textile and other industries for water treatment structures, to achieve flow and liquid level control, which is an important equipment for water supply and drainage and sewage treatment.

This gate is suitable for pipeline openings and intersecting manholes, sedimentation tanks, diversion channels, pump station inlets, and other locations.
