Pressure probe

Abstract

The invention relates to a pressure probe, which comprises a probe casing 3 and a probe head 10, wherein the probe head 10 is arranged on the probe casing 3, the probe head 10 forms a sealed cavity with the interior of the probe casing 3 and is provided with a pressure drainage pipe 8, and the probe casing 3 is provided with a cooling water supply pipe 7 and a cooling water outlet 5 which are led to the interior of the probe head 10. The pressure probe has the advantage that by arranging the cooling water supply pipe, the probe can be cooled when the probe works in the high-temperature environment, and the purpose of accurately measuring the pressure in the high-temperature environment is realized.

Description

technical field [0001] The invention relates to a probe, especially a pressure probe. Background technique [0002] A pressure probe is a device for measuring the fluid pressure in a pipeline, and is mainly used for measuring the pressure in a high-pressure pipeline. In recent years, with the development of technology, the pressure and temperature of the fluid in the pipeline have increased significantly. In order to accurately obtain the pressure data of the fluid in the pipeline, or as a scientific research need, or to avoid danger due to pressure out of control, the pressure probe Stable work of the needle is very necessary. At present, many measurements need to be carried out at higher temperatures, the highest temperature can reach 1300 ° C, and most of the pressure measuring probes on the market are used in high pressure and low temperature environments. For pressure measurement with high temperature and high pressure requirements Environment, due to material or stru...

Problems solved by technology

At present, many measurements need to be carried out at higher temperatures, the highest temperature can reach 1300°C, and most of the pressure measuring probes on the market are used in high pressure and low temperature environments. For pressure measurement with high temperature and high pressure requirements environment, existing products have poor high temperature capability due to material or structure reasons, and cannot achieve accurate measurement
