Expect characteristic, Curie point is lower (120 DEG C or so), general to require probe in order to guarantee the reliability of transducer
Operating temperature control within 80 DEG C, the high temperature higher than 80 DEG C is affected to the working performance of piezoceramic transducer, very
Extremely sensor is damaged and cannot be worked.Industrial online high temperature ultrasonic wave detection is one of the field under this working condition
Hang-up.In patent 02241098.X, when outer patch ultrasonic probe energy converter is to high-temperature medium Level measurement, probe is exactly to adopt
With heat-radiating rod radiating mode, the problem is preferably resolved to a certain extent, but practical experience is found, at 150 DEG C or more
Using unsatisfactory, transfinite to guarantee the temperature at probe not, need heat-radiating rod very long, heat-radiating rod is too long certainly will to increase ultrasound
The decaying of wave signal reduces signal-to-noise ratio, influences the normal detection of signal, be more difficult to take into account heat dissipation and signal-to-noise ratio at 200 DEG C or more
Both sides requirement, to not can be carried out reliable detection.To find out its cause, it mainly uses radiating principle, heat-radiating rod is generally adopted
With the preferable aluminium of heating conduction or copper material, its simultaneously also can be continuously quick from high temperature measurand to space heat elimination
It absorbs and transmits heat to energy converter, cause the main reason for heat-radiating rod terminal temperature remains high when equalized temperature.
Utility model content
Utility model aims to solve in Ultrasonic Nondestructive high temperature measurand, temperature is higher, it is desirable that
Heat-radiating rod is longer, the poorer this contradictory problems that cannot be considered in terms of of signal-to-noise ratio, provides under a kind of more simple and reliable progress high temperature
The ultrasonic probe of non-destructive testing.
For this purpose, the utility model provides a kind of ultrasonic measurement probe of on-line checking under suitable high temperature, it is characterized in that: extremely
It less include support, energy converter cavity and ultrasonic transducer, ultrasonic transducer is connected in energy converter cavity, ultrasonic waves
There can be guided wave stick between device and support, guided wave nose is fixed with support；Rear end is connect with ultrasonic transducer.
The guided wave stick includes: seal chamber, high temperature guided wave oil, and high temperature guided wave oil is filled in seal chamber.
The seal chamber uses stainless steel material.
The seal chamber front end puts in the vallecular cavity of support and fixes, and ultrasonic transducer surface is close high temperature guided wave oil
Seal the chamber other end.
The guided wave stick uses composite material, and composite material is constituted by leading sound core material and radiator.
The guided wave stick surrounding is provided with fin cooling fin.
The seal chamber surrounding of the guided wave stick is provided with fin cooling fin.
The seal chamber has liquid injection port close to one end of ultrasonic transducer.
The utility model has the beneficial effects that the utility model when to high temperature measurand detect when, the part of measurand
By fin cooling fin to space heat loss through radiation, the thermal Finite conducted by high temperature guided wave oil will not influence sound wave and exists heat
The big variation of the velocity of sound that the conduction of high temperature guided wave oil generates.The utility model structure is simple, it is convenient, at low cost to realize.
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
