High temperature and high pressure resistant petroleum instrument

Abstract

The invention discloses a high temperature and high pressure resistant petroleum instrument which comprises an instrument body. The instrument body comprises a detection probe, a display screen and adetection chip, the detection probe is in sealing connection with a flange via sealing cushion, and is connected to a petroleum pipeline via the flange; toughened glass is arranged just facing the display screen, and fixed to the front side of a protective cover via a buckle; and the back side of the protective cover is fixedly connected to the instrument body via bolt installing columns, the outer periphery of the instrument body is composed of radiating fins, a high temperature isolated sheath layer and a fireproof filling layer are arranged outside the radiating fins successively, and the fireproof filling layer is laid on the inner wall of the protective cover. The high temperature and high pressure resistant petroleum instrument is simple in structure and convenient to use; the high temperature isolated sheath layer enables the whole petroleum instrument to resist high temperature, and the radiating fins arranged in the outer surface of the instrument body can be used to improve the high temperature resistance of the high temperature isolated sheath layer; and further a balancing air valve stabilizes the air pressure in the whole petroleum instrument, and the petroleum instrument is more resistant to high temperature and high pressure.

Description

technical field [0001] The invention relates to a petroleum meter, in particular to a high temperature and high pressure resistant petroleum meter. Background technique [0002] my country's petrochemical industry is developing in the direction of large-scale, large-scale and internationalization. Since the petrochemical industry requires long-term and continuous production, the American Petroleum Institute standard API610 stipulates that the continuous operation life of the pump set should be at least 3 years. At present, the high-temperature and high-pressure horizontal single-stage cantilever pump can meet the high temperature and high saturation requirements of petrochemical equipment during reuse. Medium requirements for steam pressure; however, there is no supporting high-temperature and high-pressure instrument for supporting use. During use, the state of high-temperature and high-pressure horizontal single-stage cantilever pumps cannot be detected in real time; in or...

Since the petrochemical industry requires long-term and continuous production, the American Petroleum Institute standard API610 stipulates that the continuous operation life of the pump set should be at least 3 years. At present, the high-temperature and high-pressure horizontal single-stage cantilever pump can meet the high temperature and high saturation requirements of petrochemical equipment during reuse. Medium requirements for steam pressure; however, there is no supporting high-temperature and high-pressure instrument for supporting use. During use, the state of high-temperature and high-pressure horizontal single-stage cantilever pumps cannot be detected in real time; in order to meet the market needs to provide high-quality high-temperature and high-pressure oil meter

[0003] Existing petroleum instruments cannot be applied to high temperature and high pressure for a long time, and the long-term high temperature will easily burn out the precision components inside the instrument; and the high-pressure environment will affect the normal use of precision components in the instrument, which not only greatly shortens the use life; also affects the accuracy of meter measurement
