Heavy oil inflow prevention device to heavy oil pressure detector

摘要

The present invention relates to a pressure detecting device for detecting heavy oil pressure, and more particularly, a pressure detecting instrument connected to the heavy oil conveying pipe through a pressure pipe so that heavy oil does not penetrate into the pressure detecting instrument to detect the heavy oil pressure. The present invention relates to a device for preventing the inflow of heavy oil into a heavy oil pressure detection instrument that enables to stably detect heavy oil pressure.;As the constitution, the present invention connects the heavy oil feed pipe 110 and the heavy oil pressure detector 160 to the pressure pipe 120, and the pressure pipe 120 is filled with antifreeze by the antifreeze port 140. In the heavy oil pressure detection device capable of detecting the heavy oil pressure, the pressure pipe 120 between the antifreeze port 140 and the heavy oil conveying pipe 110 is separated by a flexible diaphragm 24, the diaphragm 24 is characterized in that it is supported by the upper and lower body 10 (11) forming the passage 14, 15 on one side and the hollow portion 12, 13 on the other side.
