Description: The first-stage valve gasket of a hydrogen compressor is a consumable of the reciprocating compressor valve assembly. It is installed between the first-stage valve and the cylinder valve seat mating surface to seal the joint gap and is suitable for the first-stage hydrogen compression operation.
It fills the gap between the valve and cylinder mating surfaces to prevent hydrogen from leaking out from the flange joint and ensures that the compressed medium inside the cylinder does not cross-leak internally. It also buffers the assembly clamping force, compensates for minor deformation of the mating surfaces, and protects the valve seat and cylinder sealing surfaces.
‑ Flat‑form sealing gasket.
‑ For hydrogen‑compression service: non‑metallic composite sealing material featuring hydrogen‑embrittlement‑resistance, high‑pressure‑resistance and corrosion‑resistance; with proper elasticity for alternating‑pressure operating environment.
