Abstract

The invention discloses a pressure regulator capable of being remotely controlled, and relates to the technical field of gas pipe networks. The pressure regulator disclosed by the invention is composed of three parts, that is, a main regulation component, a commander and a control component, wherein the control component controls the commander to set a pressure, thereby realizing remote regulation; the commander is designed to carry out spring regulation and gas regulation simultaneously, and capable of realizing local regulation and remotely-controlled regulation; and during running, a predetermined pressure is set in the spring regulation, and then the remote regulation is carried out on the basis of the predetermined pressure, so that maintenance for the pressure of a gas pipe network above the predetermined pressure in the case of a fault of the control component is ensured, downstream gas supply is ensured, and the pressure regulator is safer and more reliable. The pressure regulator disclosed by the invention has the remarkable advantages of being compact in structure, convenient to install and use, good in sealing performance, long in service life, convenient to maintain, capable of being remotely regulated and locally regulated, high in accuracy, wide in pressure regulation range and the like.

Description

technical field [0001] The invention relates to the technical field of gas pipeline network, in particular to a remote-controllable pressure regulator. Background technique [0002] In recent years, with the rapid development of my country's national economy, the requirements for fluid transmission and distribution equipment are getting higher and higher. Especially with the rapid development of my country's natural gas industry and urban gas consumption, the requirements for the accuracy and range of pressure regulators are getting higher and higher. Conventional regulators can only be operated on site and do not have the function of remote pressure regulation. Conventional regulators need to be operated on site by rotating the pilot screw to adjust the regulator, and the precision and range of pressure regulation are controlled by the pilot. The pressure spring is affected, the precision is poor, and the pressure adjustment range is narrow. When it is necessary to change...
