Abstract
The utility model relates to a high temperature gas pressure taking device. The utility model is characterized in that the pressure taking device mainly comprises a pressure guiding joint 10 which is provided with a pressure taking pipe 11, and an oil cylinder 7 which is connected with the pressure guiding joint 10, wherein the inner part of the oil cylinder is provided with a shoulder hole 12 which is provided with a metal diaphragm seat 8 which is provided with a through hole 13. A metal diaphragm 9 is arranged on the metal diaphragm seat 8, and silicone oil 6 which is arranged on a silicone oil passage 5 of the inner part of the oil cylinder and a hole of the pressure taking pipe 11 of the pressure guiding joint are spaced by the metal diaphragm 9. Because the utility model adopts the metal diaphragm type silicone oil to transfer pressure, a pressure taking diaphragm of a pressure sensor is sufficiently contacted with the silicone oil, the pressure is transferred to the pressure taking diaphragm of the pressure sensor in a lossless way and the accuracy of pressure measurement is high. The pressure taking diaphragm of the pressure sensor is not directly contacted with high temperature media, therefore the service life of the pressure sensor is extended and the pressure sensor is prevented from being damages because of the stress of the concretion and the icing of the media. The utility model solves the unsafe problems of leakage and bursting of the pressure guiding pipe because of the problem of manufacturing engineering. Besides, the utility model also has the advantages of easy manufacture, convenient installation, etc.
