Claims (1)
冷却室を形成し、且つ高温高圧側を形成する傘部
表面部にこれを覆うように耐熱性、耐食性に優れ
、且つ熱伝導率の小さいスキン材を溶着して被覆
層を形成すると共に被覆層と上記傘部表面部との
間に複数に分割された断熱空間部を形成したこと
を特徴とするポペツト弁。 A cooling chamber is formed inside the poppet valve's cap to cool it, and a skin with excellent heat resistance, corrosion resistance, and low thermal conductivity is used to cover the cap's surface, which forms the high temperature and high pressure side. A poppet valve characterized in that a covering layer is formed by welding materials together, and a plurality of heat-insulating spaces are formed between the covering layer and the surface of the umbrella portion.
