By arranging the cooling water supply pipe, the pressure probe can be cooled when working under the high-temperature environment, and the purpose of accurately measuring pressure under the high-temperature environment is realized.
Description
Technical field
The utility model relates to a kind of probe, especially a kind of pressure probe.
Background technology
Pressure probe is a kind of device of measuring channel fluid pressure, is mainly used in the measurement of pressure piping internal pressure.In recent years, along with the development of technology, the pressure and temperature of pipeline inner fluid is all significantly improved, in order to obtain accurately the pressure data of pipeline inner fluid, or need as scientific research, or avoid because pressure runaway is caused danger, the steady operation of pressure-measuring probe is very important.At present, a lot of measurements is at higher temperature, to carry out, the highest temperature can reach 1300 ℃, and now the pressure-measuring probe on market is applied in the environment of high pressure, low temperature mostly, for the pressure measurement environment that has high temperature, high pressure requirement, existing product is due to reasons such as material or structures, and high temperature capabilities is poor, can not realize Measurement accuracy.
Summary of the invention
The purpose of this utility model is to provide high, the resistant to elevated temperatures pressure probe of a kind of measuring accuracy.
Technical solution of the present utility model is as follows: pressure probe comprises probe housing, probe, described probe is arranged on probe housing, probe forms the cavity of sealing and is provided with pressure guiding pipe with probe housing is inner, described pressure guiding pipe one end is provided with pressure entrance, described pressure entrance is arranged on pop one's head in also upper and exterior, the other end of pressure guiding pipe is arranged on pressure-measuring-point through probe housing, on probe housing, by screw thread, set nut is installed, described probe housing is provided with and leads to probe inner cooling water supply pipe and coolant outlet.Described pressure guiding pipe is a plurality of, also can in same plane, direction, be one or more groups pressure guiding pipe of 90 ° of distributions for 2 pressure entrances.Described pin housing and probe, pressure guiding pipe and probe housing and probe, cooling water supply pipe and probe housing are by being welded to connect.Described probe adopts high temperature alloy manufacture, and as GH3044, GH3128 etc., the head of probe is circular arc.
The utility model, in when work, when measures ambient temperature is very high, injects cold water by cooling water supply pipe to probe interior, and discharges by coolant outlet, forms circulation, probe is carried out cooling, has guaranteed probe reliably working under the environment of High Temperature High Pressure.Meanwhile, each several part of the present utility model is by being welded to connect, compact conformation, reliable operation; Described pressure guiding pipe is a plurality of or 2 pressure entrances are one or more groups pressure guiding pipe of 90 ° of distributions in same plane, direction, can make pressure probe adapt to multiple environment for use, realizes stagnation pressure and the static pressure of measuring respectively same cross section in runner; The set nut arranging on probe housing can make the accurate align with tube inner fluid of the pressure entrance of pressure guiding pipe carry out flow path direction, measures accurately; Probe adopts high temperature alloy manufacture, and resistance to elevated temperatures is good, when temperature is higher than the permissible value of probe material in pipeline, can passes into chilled water and carry out coolingly, can further improve its heat resistance.The head of probe adopts circular surface, can reduce flow resistance, guarantees the accurate of measurement.
