Cast iron copper inlaid square gate

Product Name:Cast iron copper inlaid square gateCopper inlaid cast iron square gate

Product models: ZMQF, SFZ

Product specifications: DN200 * 200-DN3000 * 3000

Structural form: open pole type, bi-directional pressure bearing type

Drive mode: Hand wheel, hand cranked, and flashlight dual-purpose opening and closing machine

Installation form: wall mounted, flange mounted

Applicable media: sewage, seawater, clean waterCast iron copper inlaid square gateIt is mainly composed of a gate seat, gate plate, copper sealing element, 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 is 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, rigidity, wear resistance, corrosion resistance, and pressure bearing capacity are high.

Adopting pre embedded steel plates or pre embedded bolt installation, it is easy to install, debug, use, and maintain, with a long service life.

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.

Complete variety specifications and wide adaptability.

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, motor, pneumatic, hydraulic mechanism to drive the gears, worm gears and other components of the transmission device, and drives the transmission nut or screw to rotate, causing the gate shaft to move vertically up and down, thereby opening or closing the gate, achieving the purpose of water, closing water or adjusting water level.

Main technical performance parameters: 1. Model and specifications:

Square gate: rising pole ZMFDN200~DN2500mm

Main performance indicators: a) The clearance between the sealing surfaces 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.
