させるなどの種々の困難を生じさせていた。Conventional technology In conventional valves, the valve body guide is fixed to the valve body or valve seat, so a gap is formed between the valve body and the valve body guide, and the valve passes through this gap during valve operation. It was common for fluid to leak into the valve other than the passageway when the valve was opened. Therefore, if the fluid is granular or contains granules,
In fluids such as ethylene decomposition gas, where carbon etc. precipitate and solidify due to fluid leaking into the valve, pressure expansion, temperature drop, etc., particulate matter accumulates inside the valve, causing valve malfunction. This has caused various difficulties such as deterioration of sealing performance.
