Abstract
The utility model relates to a thermometric element shock resistance device, which comprises a thermometric element, a mounting part and a protective sleeve. The mounting part is fixedly mounted on a technical pipeline wall; the protective sleeve is connected with the mounting part; the sum of the length of the protective sleeve and the length of the mounting part is larger than the length of the thermometric element inside the technical pipeline; and the inner diameter of the protective sleeve is the same with that of the mounting part. The thermometric element shock resistance device has a simple structure, is convenient to mount, and is simpler to operate. As the protective sleeve is used for realizing shock resistance protection on the thermometric element; the service life of the thermometric element is prolonged; and the maintenance work load and maintenance cost of instruments are reduced. Besides, as the end part of the protective sleeve is notched or tapped, the medium liquidity is increased; the excellent contact between the thermometric element and a medium is guaranteed; and the temperature measuring timeliness and accuracy are guaranteed.
Description
Technical field
The utility model relates to the shock proof device of a kind of temperature element, specifically is the shock resistance sleeve pipe of a kind of temperature element such as thermopair, thermal resistance.
Background technology
Industrial temperature element mainly contains thermopair and thermal resistance two big classes, and its effect is that temperature signal is converted to the Detection ﹠ Controling that electric signal carries out temperature.Temperature element is widely used in systems such as blast furnace, heat generator, heating furnace, sintering, system oxygen.The temperature element installation quality directly has influence on the stability and the control accuracy of control system work.Particularly the temperature element on the process pipe at the pipe medium pressure height, when flow is big, can be subjected to bigger impact, particularly when medium produces water hammer or pneumatic hammer effect because of pulsation, can directly cause the damage of temperature element, and what the influence construction was produced normally carries out.
The utility model content
The purpose of this utility model is to provide a kind of protective device of process pipe temperature element, makes temperature element such as thermopair, thermal resistance avoid being subjected to direct intense impact, plays the effective protection to temperature element.
The utility model is achieved in that
A kind of temperature element anti-impact device; comprise temperature element; installing component and protective casing; it is characterized in that: described installing component is fixedly mounted on the process pipe wall; protective casing is connected with installing component is coaxial; the length sum of protective casing and installing component is greater than the length of temperature element in process pipe inside, and protective casing is identical with the internal diameter of installing component.
In order to make temperature element have better thermometric effect, further scheme is: cutting away from the end dislocation of process pipe wall at protective casing has otch, the temperature-sensitive point of the corresponding temperature element of incision.
The preferable quantity of otch is 3 to 5.
Also can be at the end dislocation perforate of protective casing away from the process pipe wall, the temperature-sensitive point of the corresponding temperature element of tapping.
In addition, owing to temperature element uses in high-temperature medium, so protective casing should use exotic material.
In addition, in use, should guarantee that protective casing cut-out direction and MEDIA FLOW to consistent, be convenient to media flow, make things convenient for thermometric, and can guarantee that thermometric is accurate.
Described temperature element is an occasionally thermal resistance of thermoelectricity.
Described installing component and protective casing, installing component are installed by the mode of welding with the process pipe outer wall and are connected.
In addition, for ease of enforcement, the utility model also provides the installation method of described temperature element anti-impact device, comprises the steps:
Parameter values such as step 1, the specifications and models of determining temperature element and length;
After installing by above-mentioned steps, according to field environmental condition and the actual installation temperature element that requires, connect measurement line, carry out electric part and install, and temperature element installed by installing component, installing component installs and fixes temperature element by screw thread or flange.
Principle of work of the present utility model is: because the temperature-sensitive position of temperature element is in tip position; in the medium pipeline during high pressure media flow; its impact force action is on the protective casing of temperature element outside; play protective effect to temperature element; medium guarantees the accuracy that temperature element is measured by the otch or the aperture circulation of protective casing termination in addition.
The disclosed temperature element anti-impact device of the utility model is simple in structure; be convenient to install, and installing component welded together with protective casing earlier when installing, then installing component, protective casing integral body are being stretched into medium pipeline; saved operation like this, and operation is simpler.The utility model utilizes protective casing to realize the shock resistance of temperature element is protected, and has prolonged the serviceable life of temperature element, reduces instrument maintenance workload and maintenance cost.In addition,, increased the flowability of medium, guaranteed that temperature element contacts with the good of medium, guaranteed the promptness and the accuracy of thermometric in the end cut or the perforate of protective casing.
