Abstract
Description
本実施形態に係るゲート弁10は、図1Aに示すように、直線状の流路12が形成された弁箱14と、流路12に直交する軸方向に昇降することで流路12を開閉する弁体16と、弁体16を収容する弁室18と、弁体16の基端部16aから軸方向に伸び出た弁棒20とを備える。流路12を流れる流体は、空気や蒸気(水蒸気を含む)等の気体、真空圧等の減圧気体、水や油等の液体、又はゲルや固体粒子と液体との混合物等の流動体であり、ゲート弁10はこれらの流体の流れを開閉できる。
図5Aに示すように、本実施形態のゲート弁40は、弁体16A及び流路12に形成される凹部50の形状において、図1Aのゲート弁10と異なる。なお、ゲート弁40において、図1Aのゲート弁10と同様の構成については同じ符号を付してその詳細な説明を省略する。
図7に示すように、本実施形態のゲート弁60は、流路12側にシール部61が設けられている点で、図1Aのゲート弁10と異なる。なお、ゲート弁60において、図1Aのゲート弁10と同様の構成については同じ符号を付してその詳細な説明を省略する。
図8Aに示すように、本実施形態のゲート弁70は、弁体16Bの構成及び連通路72を有する点において、図5A及び図5Bのゲート弁40と異なる。なお、ゲート弁70において、図5A及び図5Bのゲート弁40と同様の構成については同じ符号を付してその詳細な説明を省略する。

- 請求項5記載のゲート弁であって、前記凹部(30)の曲率が前記凹部(30)に当接する部分の前記弁体(16)の外表面の曲率と略同じであるゲート弁。
- 請求項1記載のゲート弁であって、前記弁室(18)は前記流路(12)に向かって縮径するテーパ面を有し、前記弁体(16)を前記流路(12)に降下させたときに、前記弁室(18)のテーパ面に前記弁体(16)のテーパ部が当接して前記弁室(18)を閉塞するゲート弁。
- 請求項7記載のゲート弁であって、前記弁室(18)は前記弁体(16)の体積と略同じ容積であるゲート弁。
- 請求項1〜8のいずれか1項に記載のゲート弁であって、前記流路(12)に前記弁体(16)と気密又は液密に密着するシール部(61)が設けられているゲート弁。
- 請求項1〜9のいずれか1項に記載のゲート弁であって、弁閉状態において、前記流路(12)の上流側の流体からの圧力により前記弁体(16)を前記弁室(18)側へ押し上げる力と、前記弁室(18)の圧力により前記弁体(16)を前記流路(12)側へ付勢する力とをバランスさせたゲート弁。
- 請求項1〜9のいずれか1項に記載のゲート弁であって、前記弁室(18、48)と前記流路(12)の上流側とを連通させる連通路(72)を備え、弁閉状態において前記弁室(18、48)の圧力により前記弁体(16)を前記流路(12)側へ付勢する、ゲート弁。
