Claims (3)
- 軸心方向に沿って貫通する流路が設けられ且つ前記流路の途中に弁体が設けられて前記流路の一方向にのみ流体の流通が可能に構成された逆止め弁ユニットが本体の穴内に装着されて構成される逆止め弁装置であって、
前記逆止め弁ユニットの軸心方向の両端部の外形が円錐状に形成されており、前記円錐状の両端部が、前記本体自体または前記穴に設けられた雌ねじに螺合する固定部材に設けられた2つの円錐状の穴に挿入されており、
前記円錐状に形成された円錐面の開き角度が前記円錐状の穴の錐面の開き角度よりも小さくなっており、これにより、前記固定部材が前記雌ねじに締め込まれることによって前記円錐状に形成された円錐面の先端部が前記円錐状の穴の錐面に当接し、そこにメタルシールが形成されてなる、
ことを特徴とする逆止め弁装置。 - 前記本体には、前記穴が貫通して設けられており、前記穴には少なくともその両開口部に前記雌めじが設けられ、2つの前記雌ねじにはそれぞれ前記固定部材が締め込まれ、2つの前記固定部材によって前記逆止め弁ユニットが固定されてなる、
請求項1記載の逆止め弁装置。 - 前記逆止め弁ユニットには、一端が前記弁体に当接して前記弁体を弁座に押し付けるためのコイルスプリングが設けられ、
前記本体および前記固定部材のいずれにも、前記コイルスプリングの他端が当接するための凹部が設けられ、
2つの前記円錐状に形成された円錐面の開き角度が互いに同じであり、かつ、2つの前記円錐状の穴の錐面の開き角度が互いに同じであり、
前記本体の穴内への前記逆止め弁ユニットの挿入方向を変えることで流体の流通方向を逆転させることができるように構成されている、
請求項1記載の逆止め弁装置。
