Intelligentfuel gas pressure regulator and application method

Abstract

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.

Description

technical field [0001] The invention relates to a gas pipeline pressure regulating device, in particular to an intelligent gas pressure regulator and a use method. Background technique [0002] Urban intelligent construction is a project vigorously promoted by the government, among which "smart pipe network" is an important part of the urban intelligent project. Construct a remote control system with intelligent judgment and adaptive adjustment capabilities, realize remote control of medium and low pressure pipeline networks, gradually realize functions such as gas distribution, protection, and feedback, realize data fusion of various systems, and improve production and operation efficiency. "The goal of construction. [0003] The gas pressure regulator is a device that keeps the outlet gas at a specified pressure by automatically changing the gas flow through the regulating valve. The gas pressure regulator is a special valve on the gas pipeline, which can keep the downst...

Problems solved by technology

[0007] (1) The disadvantage of the membraneless voltage regulator is that the response speed is slow, and the voltage regulation function is lost after power failure;

[0008] (2) The disadvantages of pneumatic control regulators are that there are many equipment accessories, complex structure, large volume, slow response speed, and failure after the equipment is powered off.
