Abstract
The invention discloses a temperature sensor, which comprises a cable, a conical plug and a thermocouple. The cable is connected with the thermocouple. The thermocouple consists of two thermocouple wires and a metallic shell, wherein the thermocouple wires are packaged in the metallic shell and one end of the metallic shell is connected with the conical plug. The invention additionally discloses an installation method of the temperature sensor. The structure of the temperature sensor solves the problem in sealing between the temperature sensor and the conical sealing plug, the installation and sealing structure of the temperature sensor solves the problem in leading out the cable of the temperature sensor in a container, the temperature sensor has the characteristics of simple structure, convenience in installation and good sealing performance, and especially the sealing performance can be kept to be good when the internal pressure of the container is changed between low pressure and high pressure.
Description
Technical field
Embodiments of the invention relate to a kind of temperature sensor that is used for thermometric, and more particularly the embodiment of the invention relates to a kind of temperature sensor that is used for the inner thermometric of superhigh-pressure high-temp pressure vessel.
Background technology
The part in high temperature pressure vessel with liquid as actuating medium; Because the direct interior actuating medium temperature of measuring vessel; At present people replace through measuring the actuating medium temperature that gets into before the container; And the actuating medium in the entering container is owing to carry out exchange heat with container etc., the temperature of actuating medium with get into inconsistent before the container.So this metering system lacks accuracy.At present, do not find the documents and materials measured about middle high temperature, high pressure vessel internal work medium temperature.
Summary of the invention
Work is to pressurize as medium and heat with liquid to the part high pressure vessel.For direct surveying work medium temperature; Must draw pressure vessel at the internal tank mounting temperature sensor and with its cable; Owing to must effectively seal under the environment of superhigh-pressure high-temp, otherwise possibly cause container internal pressure to descend, and security incident might take place owing to revealing.Therefore, need a kind of temperature sensor of design.The planform of this temperature sensor can realize the sealing of the mounting interface of ultrahigh pressure vessel temperature sensor below 300 ℃.
The present invention is achieved in that
A kind of temperature sensor comprises cable, conical plug and thermopair, and cable is connected with thermopair, and thermopair is made up of two galvanic couple silks and betal can, and the galvanic couple silk is encapsulated in the betal can, and an end of betal can is connected with tapered plug.
Described betal can is connected with the mode of conical plug through welding.
The part that described betal can is positioned at tapered portion beyond the Great Wall is a closed state.
Described betal can is circular.
Described tapered plug is a metal material.
Described tapered plug is installed in container exit.
Thereby described cable is connected the thermometric of realizing container inner medium with the outer electronic installation of container.
The present invention also further discloses the installation method of said temperature sensor, is specially:
Thermopair is stretched in the container; The conical plug outside of temperature sensor is equipped with the conical surface seal plug; Between tapered plug and conical surface seal plug, cone washer is installed; Be movably installed with pressing plate at internal tank, the conical plug of pressing plate extrusion temperature sensor makes cone washer deform, thereby seals the conical plug of temperature sensor and the gap between the conical surface seal plug.When conical plug received the working medium pressure of internal tank, it was tightr to fit between the conical plug of temperature sensor and the conical surface seal plug, has guaranteed the conical plug of temperature sensor and the sealing between the conical surface seal plug.Realized the more effective self-energized seal of the big more sealing of pressure simultaneously.
And conical surface seal can be installed a plurality of sensors beyond the Great Wall simultaneously.Adopt the O-ring seals sealing between conical surface seal plug and the pressure vessel installation site, the sealing when being used to boost the process mesolow.Utilize the metal conical surface seal during high pressure.With pressing plate locking, realize the sealing on all composition surfaces after the aggregate erection.
This structure of temperature sensor has solved temperature sensor and conical surface seal plug sealing problem; And the temperature sensor installation sealing structure has solved the problem that the cable of temperature sensor in the container is drawn; Have simple in structure; All can keep good sealing when changing between inherent low pressure of characteristics, particularly container easy for installation, good airproof performance and the high pressure.
The temperature sensor and the encapsulating method thereof that are used for superhigh-pressure high-temp internal tank thermometric make that the temperature sensor big more sealing of pressure under pressure is effective more, realize self-energized seal.The sealing method efficiently solves the sealing problem that temperature sensor under the superhigh-pressure high-temp is drawn mounting interface, and sealing effectiveness is good.
