Background
During the exploitation process of the oil-water well, the pressure of oil in the oil-water well needs to be regularly measured by using a pressure gauge. But because temperature is lower in winter, when the staff used the pressure gauge to measure the pressure of oil-water well, oil took place to freeze in the easy immersion pressure gauge of fluid, and then damaged the pressure gauge and caused the measuring result inaccurate.
At present, in an extremely cold environment with the air temperature below 0 ℃, when the pressure of flowing liquid is measured, a small hole is formed on a measured pipeline or a container, a short screw joint head with the length of 15-20cmDN15 is welded, and then a valve and a pressure gauge or a pressure sensor are installed. The measured medium directly enters the nipple head through a pipeline or a container, then the valve is opened, and the measured medium touches the pressure gauge or the sensor through the valve to transfer pressure.

The conventional solution is to keep the temperature, wind the electric tracing band, use hot water to circularly trace heat or remove the pressure gauge, mount the pressure gauge when measuring the pressure, and then use hot water or steam to scald the pressure measuring short joint. The methods have the disadvantages of poor effect, high cost and complicated work, and can not accurately and timely reflect the pressure of a measured medium, so that the antifreezing pressure measuring joint for the oil-water well is provided.
