Abstract

【課題】　ゲージピンを単にステムの往復動に連動させるだけでなく、構造簡単でありながらステムの往復動を精度よくゲージピンに反映させることで僅少量である弁体のシール摩耗量を正確に測定することができる往復動バルブの提供。 【解決手段】　ピストン１に連結されたステム２と、ステムの先端に取り付けられた弁体３と、バルブ本体４に連結したヨーク４１にヨーク内部からヨーク外部に貫通して形成されたガイド孔５と、ステムの往復動に連動して往復動するゲージピン６とを備え、ゲージピンが、ガイド孔からの突出量の変化を確認できるように、その先端面６０がヨーク外部に突出する状態でガイド孔内に挿通され、ゲージピンは基端面６１がピストンにスプリング６２による付勢力によって常に押圧状態で当接するように支持されている。
