定义
A precision-engineered sealing component installed between mating surfaces of control gates to create a leak-proof barrier against liquids, gases, or particulates. It compensates for surface irregularities, thermal expansion, and mechanical vibrations while maintaining system pressure and preventing contamination.
工作原理
Works by compressive deformation to fill microscopic gaps between mating surfaces, creating a mechanical seal through elastic recovery and surface adhesion. The sealing action relies on material compression, surface finish compatibility, and proper bolt loading to maintain continuous contact pressure across the sealing interface.
材料
Typically made from elastomers (EPDMNitrileViton)PTFEgraphitemetal (stainless steelcopper)or composite materials. Material selection depends on temperature range (-40°C to 300°C)pressure (up to 300 psi)chemical compatibilityand media type.
Hardness
50-90 Shore A
Thickness
1.5-6.0 mm
Compression Set
<20%
Pressure Rating
0-300 psi
Tensile Strength
>10 MPa
Temperature Range
-40°C to 250°C
标准
ISO 9001ISO 14001DIN 3750ASME B16.21

常见问题

How often should control gate sealing gaskets be replaced?

Replacement intervals depend on operating conditions: typically 12-24 months for continuous service, or based on visual inspection for compression set, cracking, or chemical degradation.

What are common failure modes for sealing gaskets?

Common failures include compression set, chemical swelling, thermal degradation, bolt relaxation, and improper surface finish leading to leakage paths.
