１項記載の減圧弁の予防保全機構。[Claims for Utility Model Registration] 1. The elastic force of a pressure setting spring is applied to the upper surface of the diaphragm, and the secondary pressure is applied to the lower surface,
In a pressure reducing valve that maintains a constant outlet pressure by opening and closing the valve port to control the flow rate based on the balance of both forces, the axial direction of the adjusting screw that adjusts the elastic force of the pressure setting spring is 1. A preventive maintenance mechanism for a pressure reducing valve, characterized in that its displacement, that is, its position, is confirmed by comparing it relative to a scale attached independently to its adjustment screw. 2. The preventive maintenance mechanism for a pressure reducing valve according to claim 1, wherein the position of the adjusting screw is confirmed by a position detection sensor attached independently of the adjusting screw.
