The invention discloses an intelligent
fuel gas pressure regulator and an application method. The
pressure regulator comprises a valve body, a valve element, a valve rod and a disconnecting device. The valve body comprises an inlet cavity and an outlet cavity. The valve element and the valve rod are arranged in the valve body. The
pressure regulator further comprises a valve element pushing device, a leakage sensor and a displacement sensor. The leakage sensor is arranged on a valve body upper membrane shell, and the displacement sensor is arranged on a bottom cover of the valve body. The valve element pushing device comprises a bourdon tube, an electric
actuator, a spring seat, a spring and a leas screw, wherein the spring is arranged on the spring seat, and the spring seat is arranged in the bourdon tube; the electric
actuator is fixed to the top of the bourdon tube, and an output shaft of the electric
actuator is connected with the lead screw; and a nut is fixed to the spring seat and is in threaded connection with the lead screw. According to the intelligent
fuel gas pressure
regulator and the application method, the structure of the
regulator is reasonable, the components of the electric actuator, the leakage sensor, the displacement sensor and the like are arranged,
remote control, fault self-diagnosis and outage self-regulation are integrated, and the
regulator has the characteristics of being safe, practical, high in
reaction speed, and high in pressure stabilizing precision.
