The invention provides a pressure remote monitoring device, and belongs to the technical field of pressure regulator remote control devices. The pressure remote monitoring device comprises a remote pressure regulating part and a pressure regulating execution part. The remote pressure regulating part comprises a base, a gas storage tank, a controller, a pressure transmitter, a first electromagneticvalve and a second electromagnetic valve, wherein the gas storage tank is installed above the base; a high-pressure pipe opening and a low-pressure pipe opening are formed in one side of the gas storage tank; and the first electromagnetic valve and the second electromagnetic valve are installed outside the high-pressure pipe opening and the low-pressure pipe opening correspondingly. The controller reads the pressure of the pressure transmitter, and the gas pressure of an input port of a pressure regulator is obtained; and the controller controls the first electromagnetic valve or the second electromagnetic valve to be opened, the gas storage tank is remotely loaded with the gas pressure and used for remotely controlling a director, the director is used for controlling and regulating the pressure regulator, and the gas pressure of the output end of the pressure regulator is remotely regulated. The pressure remote monitoring device is more convenient, stable and efficient to regulate.
Description
technical field [0001] The invention relates to the field of remote control devices for pressure regulators, in particular to a remote pressure monitoring device. Background technique [0002] With the large-scale construction of long-distance natural gas pipelines and the widespread popularization of natural gas applications, the urban gas transmission and distribution system has been gradually upgraded from the previous medium and low pressure systems to multi-level systems such as high pressure, sub-high pressure, medium pressure, and low pressure. During the transmission and distribution process of the system, the control of the front and rear pressures in the pipeline has become more prominent and important, and the role of the pressure regulator in the entire transmission and distribution process is particularly important. [0003] In the process of gas transmission and distribution, in order to improve the transmission efficiency of gas, the gas is usually pressurized...
