Abstract
Description
本発明のリリーフバルブでは、流体を排出するための排出孔が、ボルト形バルブボディのヘッド部の端面から起立した筒部の側面に配置され、方向変更部材によって排出孔の開放方向を所望の方向に向けることができるので、従来よりリリーフバルブの取り付け位置の自由度が高くなる。
請求項3のリリーフバルブでは、カバー体に排出孔に係止する係止突部が備えられているので、筒部に対するカバー体の回転位置が安定すると共に、カバー体が筒部から離脱することを防ぐことができる。
請求項4のリリーフバルブでは、筒部の端面から突出したカバー体操作突部をカバー体に設けたので、カバー体の回転操作が容易になる。
請求項5のリリーフバルブでは、カバー体の回転位置によらず何れかの排出孔の少なくとも一部が常に開放されるので、弁体が弁孔側から受ける流体圧力が基準圧以上になったときに、確実に流体を排出することができる。
以下、本発明の第1実施形態を図1~図5に基づいて説明する。図1に示すように、本実施形態のリリーフバルブ10は、雄螺子部20Aの基端部に平面形状六角形のヘッド部20Bを有するボルト形バルブボディ20(以下、単に「バルブボディ20」という)を備えている。バルブボディ20の中心部には、中空部屋25が形成されている。ヘッド部20Bの端面20Pには、中空部屋25の一端部が部品挿入口25Aとして開口している。また、中空部屋25の奧面の中心部とバルブボディ20の先端面との間には、弁孔11が貫通形成されている。そして、中空部屋25の奧面における弁孔11の開口縁から円筒状の弁座11Zが突出している。
以下、本発明の第2実施形態を図6に基づいて説明する。本実施形態のリリーフバルブ10Vは、カバー体45を備えていない点及び蓋体40Vが回転可能となっている点が第1実施形態と大きく異なる。具体的には、本実施形態の蓋体40Vは、排出孔14が1つのみ備えられている点以外は前記第1実施形態の蓋体40と同じになっている。そして、この蓋体40Vがバルブボディ20に対して回転可能となるように、環状突壁27が、蓋体40Vの当接フランジ41との間にクリアランスを空けた状態にカシメられている。
本発明は、上記実施形態に限定されるものではなく、例えば、以下に説明するような実施形態も本発明の技術的範囲に含まれ、さらに、下記以外にも要旨を逸脱しない範囲内で種々変更して実施することができる。
