Description

Technical Field

[0001] The utility model relates to the technical field of temperature measurement, in particular to an online temperature measurement system for a medium in a pipeline. Background Art

[0002] In industrial production, it's often necessary to measure the temperature of the medium in a pipeline. Temperature transmitters are typically used for online measurement of the medium's temperature. Temperature transmitters use thermocouples or RTDs as temperature measuring elements. The output signal from the measuring element is sent to the transmitter module. After processing through circuits such as voltage stabilization and filtering, operational amplification, nonlinear correction, V / I conversion, constant current, and reverse protection, it is converted into an electrical signal linearly related to the temperature and output as an RS485 digital signal. These transmitters are primarily used for measuring and controlling temperature parameters in industrial processes. Existing temperature transmitters (such as the pipeline temperature measurement transmitter disclosed in Application No. 201810176208.7) have their temperature measuring end installed in the pipeline, directly contacting the medium in the pipeline, sensing and measuring the medium's temperature. When a temperature transmitter malfunctions and requires maintenance, the pipeline must be disconnected before the transmitter is removed from the pipeline. During the entire maintenance process, the pipeline cannot transport the medium normally, forcing the factory to shut down. This is not only troublesome but also impacts production efficiency.

[0036] In order to better understand the present invention, the following Figure 1 - Figure 3 The working principle of the technical solution of the utility model is described in detail:

[0037] When in use, the first opening and the second opening of the three-way pipe are connected to the pipeline, and the medium in the pipeline flows into the three-way pipe. The two nuts 521 are rotated in sequence so that the two nuts 521 are separated from the sleeve 200 in sequence, thereby making the ear plate 320 separated from the sleeve 200 and driving the valve body 310 to separate from the sleeve 200, so that one end of the valve body 310 is moved away from each of the flow holes 210. At this time, the medium in the three-way pipe enters the sleeve 200 along each of the flow holes 210 and contacts the temperature measuring end of the temperature transmitter body 400. The temperature measuring end senses the temperature of the medium and measures the temperature of the medium. When the temperature needs to be measured, When the transmitter body 400 is to be overhauled, the two nuts 521 are rotated in sequence so that the two nuts 521 are sequentially close to the sleeve 200, thereby allowing the ear plate 320 to approach the sleeve 200, and driving the valve body 310 to approach the sleeve 200, so that one end of the valve body 310 blocks each of the flow holes 210. The temperature transmitter body 400 is then disassembled from the platform 630, and the temperature measuring end of the temperature transmitter body 400 is withdrawn from the slide valve 300. The temperature transmitter body 400 can then be overhauled. During the entire overhaul process, the pipeline can normally transport the medium and the factory can continue normal production, which is not only convenient but also ensures production efficiency.

[0038] The utility model provides an online temperature measurement system for medium in a pipeline, which has the following beneficial effects:

[0039] (1) Turning the two nuts 521 in sequence, so that the two nuts 521 move away from or closer to the sleeve 200 in sequence, thereby moving the ear plate 320 away from or closer to the sleeve 200, and driving the valve body 310 away from or closer to the sleeve 200, so that one end of the valve body 310 moves away from each of the flow holes 210 or blocks each of the flow holes 210 with one end of the valve body 310. When the temperature transmitter body 400 is being repaired, each of the flow holes 210 can be blocked by one end of the valve body 310 to prevent the medium in the pipeline from flowing out of each of the flow holes 210;

[0040] (2) The structure of the bracket 600 makes it easier to disassemble and assemble the sliding valve 300 and the sleeve 200;

[0041] (3) During the maintenance of the temperature transmitter body 400, the pipeline can normally transport the medium and the factory can produce normally, which is not only convenient but also ensures production efficiency.
