Abstract
The invention discloses a measuring device of a blocking position of a gas pipeline. The measuring device comprises a gas tank, and a first Pt thermometer and an exhaust pressure-resistance valve are connected to the gas tank. The gas tank is connected with the gas pipeline through a pressure-resistance flexible pipe, a second Pt thermometer is arranged on the gas pipeline, and a first pressure-resistance valve and a second pressure-resistance valve are respectively arranged on the pressure-resistance flexible pipe. A pressure sensor is connected to the pressure-resistance flexible pipe between the two pressure-resistance valves. The invention further discloses a measuring method of the measuring device. The measuring method comprises the steps that firstly, the initial pressure and temperature of gas in the gas tank are measured; secondly, the initial pressure and temperature of gas in the gas pipeline are measured; thirdly, the two pressure-resistance valves are opened, the gas in the gas pipeline flows towards the gas tank, and the pressure and temperature of the gas in a balanced state are measured; fourthly, the two pressure-resistance valves are closed, and the exhaust pressure-resistance valve of the gas tank is opened to discharge the gas; fifthly, an algorithm module in a computer is utilized to obtain the blocking position of the gas pipeline. The measuring device of the blocking position of the gas pipeline and the measuring method of the measuring device can accurately determine the blocking position of the gas pipeline.
