Stacked beam valve and stacked beam gate

叠梁阀 Stacked beam gate
Product Name: Stacked Beam Valve, Stacked Beam Door
Product model: DLZ
Product specifications: 200 * 200-3000 * 3000
Product application: The laminated beam valve is widely used in industries such as sewage treatment plants, water plants, and power plants. Used for interception purposes.
Product features: The laminated beam valve is installed in the channel and manually inserted into the channel. It has the characteristics of easy insertion and lifting, light weight, reliable sealing, good strength, long service life, and easy maintenance.

Analysis of Stacked Beam Valve and Stacked Beam Lock Technology
1. Basic Definition
Stop Log Valve:
Composed of multiple horizontal beams (usually made of metal or composite materials) vertically stacked, the pipeline is intercepted or adjusted by lowering or lifting them layer by layer, commonly used in water conservancy engineering and sewage treatment plants.
Stop Log Gate:
The structure is similar to that of a laminated beam valve, but emphasizes larger size and higher pressure bearing capacity, and is mostly used in scenarios such as reservoirs and ship locks that require rapid water retention.
2. Comparison of core features
Characteristic stacked beam valve stacked beam gate
Modular crossbeam structure, single piece can independently operate as a whole or split crossbeam, requiring coordinated lifting and lowering
Sealing method: rubber sealing strip or metal hard sealing rubber waterstop+hydraulic compression device
The pressure bearing capacity is usually ≤ 1.6MPa and can reach 2.5MPa or above (such as in ship lock applications)
Installation method: rail type/slot type, manual or mechanical lifting door slot embedded, requiring a matching hoist
3. Typical application scenarios
Stacked beam valve:
Drainage and maintenance of sedimentation tank in water plant
Temporary interception of chemical pipelines (corrosion-resistant material optional)
Stacked beam gate:
Water intake accident of hydropower station blocking water
Emergency flood control and tide blocking in river channels
4. Selection precautions
Material selection:
Freshwater environment: Q235B carbon steel+anti-corrosion coating
Seawater/corrosive medium: 316L stainless steel or duplex steel
Supporting equipment:
Stacked beam valve needs to be equipped with a lifting frame/mobile crane
Stacked beam gates require hydraulic opening and closing machines or winches
Note: The current input information does not provide directly related parameters for the laminated beam valve/gate. If specific models or technical documents are needed, additional application scenarios (such as caliber and pressure) can be added for further recommendation.
