| description | PROBLEM TO BE SOLVED: To provide a control valve that relaxes thermal impact on an abutment part surface of a valve element and an abutment part surface of a valve seat and has a long life.SOLUTION: A control valve includes: a valve body having a flow passage; a valve element abutting on a valve seat provided in the valve body with the vertical movement thereof to open and close the flow passage; and an actuator for vertically moving the valve element, where either one of surfaces of abutment parts of the valve seat and the valve element is provided with coating. A metal with a heat transfer coefficient that is higher than a material of a member coated with the coating is used for the coating.SELECTED DRAWING: Figure 1
【課題】弁体の当接部表面と弁座の当接部表面への熱影響を緩和し、寿命の長い制御弁を提供する。【解決手段】流路を有するバルブボディと、バルブボディに設けられた弁座と上下動により当接して前記流路を開閉する弁体と、弁体を上下動させるアクチュエータとを備えた制御弁であって、弁座と弁体の当接部のいずれかの表面にコーティングが施され、コーティングは、コーティングした部材の材質よりも熱伝導率が高い金属を用いている。【選択図】 図１ |
