Claims (5)
- 弁体と、この弁体を弁座に着座させて流路を閉じるばね手段と、リリーフ管路への接続部とを有し、該リリーフ管路の内部圧力がばね手段による閉弁力を超えたとき、弁体を弁座から離座させるリリーフ弁において、
上記弁座、弁体及びばね手段を有する筒状バルブボディと、
上記筒状バルブボディとは別部材からなる筒状リテイナボディとを有し、
上記筒状リテイナボディは、ストッパフランジと、このストッパフランジより小径で上記筒状バルブボディに螺合結合される螺合結合筒と、ストッパフランジの螺合結合筒の反対側に位置し、上記リリーフ管路の端部に螺合結合される管路結合筒を有し、
上記ストッパフランジにより上記螺合結合筒と筒状バルブボディとの最大螺合位置が規制されることを特徴とするリリーフ弁。 - 請求項1記載のリリーフ弁において、上記筒状バルブボディには、その軸部に、上記弁体を有する弁体アッシの弁軸を摺動自在に支持するガイド筒部が備えられており、上記弁体アッシには、筒状バルブボディ及び筒状リテイナボディの内周面に対して非接触なばね受け座が備えられており、このばね受け座と上記ガイド筒部の周囲のばね受け面との間に、上記筒状バルブボディ及び筒状リテイナボディの内周面に対して非接触な上記ばね手段を構成する圧縮ばねが挿入されているリリーフ弁。
- 請求項2記載のリリーフ弁において、上記ばね受け座は、筒状バルブボディを筒状リテイナボディに螺合結合する前の状態において、その一部が該筒状バルブボディの端部より突出するリリーフ弁。
- 請求項3記載のリリーフ弁において、上記ばね受け座は、弁体アッシの弁軸に螺合されたばね受けリングとロックナットからなっているリリーフ弁。
- 請求項1ないし3のいずれか1項記載のリリーフ弁において、上記筒状リテイナボディの螺合結合筒と筒状バルブボディとの間には、両者の間の気密を保持するOリングが圧縮された状態で介在しているリリーフ弁。
