Description

Technical Field

[0001] The utility model relates to the technical field of temperature monitoring, in particular to a non-detachable temperature meter detection and calibration device. Background Art

[0002] Currently, there are two ways to install thermometers on pipelines. One is sleeve installation, which has the advantage of easy replacement, but the measured temperature is not accurate enough; the other is direct thread installation, which has the advantage of accurate temperature measurement, but is inconvenient to replace and requires stopping the system to drain water, which makes it inconvenient to perform detection and calibration. For direct contact thermometers, calibration is impossible, and it is impossible to confirm whether the temperature displayed by the thermometer is accurate, which makes it inconvenient to use. Utility Model Content

[0003] Based on the existing technical problems, the utility model proposes a non-detachable temperature meter detection and calibration device.

[0004] The utility model proposes a non-detachable thermometer detection and calibration device, which includes a water tank, and a thermometer is fixedly connected to the upper end surface of the water tank. The thermometer includes a display end and a detection end, the display end is located on the upper surface of the water tank, the detection end is located inside the water tank, and a water connecting pipe is installed on the outer wall surface of the water tank.

[0005] Preferably, the interior of the water receiving pipe is communicated with the interior of the water storage tank, the water receiving pipe comprises a water inlet pipe and a water outlet pipe, and a flexible joint is installed on the end surface of the water outlet pipe.

[0006] With the above technical solution, the water receiving pipe is connected to the pipeline to be tested through a flexible joint, thereby facilitating the flow of the medium in the pipeline into the water storage tank and facilitating installation and disassembly through the flexible joint.

[0007] Preferably, the water inlet pipe and the water outlet pipe are respectively located on both sides of the water tank, and the water outlet pipe is located obliquely above the water inlet pipe.

[0008] Through the above technical solution, the water outlet pipe is located obliquely above the water inlet pipe, so that the medium in the pipeline enters the water tank through the water inlet pipe and is discharged outward from the water outlet pipe. When the medium flows into the water tank from the lower end and passes through the inside, it can be ensured that the medium fully contacts the thermometer, thereby obtaining accurate temperature measurement.

[0009] The beneficial effects of the present invention are:

[0010] 1. By setting a drain valve that connects the water storage tank in this application to an external closed system or pipeline through a water connection pipe, the medium in the system or pipeline flows into the water storage tank through the drain valve, thereby accurately measuring the temperature of the medium in the system. The device is easy to install and simple to operate. It can be used temporarily alone or as an instrument to calibrate the temperature gauge on the pipeline.

[0011] 2. By setting up the upper and lower water outlet pipes and water inlet pipes to connect with the water storage tank, the order of medium in and out is strictly controlled so that the medium flows into the lower end of the detection box and flows out from the upper end, which helps to transfer heat to the thermometer stably and evenly, thereby improving the measurement accuracy.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Reference Figure 1-Figure 2 A non-detachable thermometer detection and calibration device includes a water tank 1, and a thermometer 2 is fixedly connected to the upper end surface of the water tank 1. The thermometer 2 includes a display end and a detection end. The display end is located on the upper surface of the water tank 1, and the detection end is located inside the water tank 1. A water connecting pipe is installed on the outer wall surface of the water tank 1.

[0017] By setting a drain valve that connects the water storage tank 1 in the present application to an external closed system or pipeline through a water connection pipe, the medium in the system or pipeline flows into the water storage tank 1 through the drain valve, thereby accurately measuring the temperature of the medium in the system. The device is easy to install and simple to operate. It can be used temporarily alone or as an instrument to calibrate the temperature gauge on the pipeline.

[0018] In order to connect the medium to be detected to the water tank 1, the interior of the water connecting pipe is connected to the interior of the water tank 1. The water connecting pipe includes an inlet pipe 3 and an outlet pipe 4. A flexible joint 5 is installed on the end surface of the outlet pipe 4. The water connecting pipe is connected to the pipeline to be detected through the flexible joint 5, so that the medium in the pipeline can flow into the water tank 1, and it is convenient to install and disassemble through the flexible joint 5. The inlet pipe 3 and the outlet pipe 4 are respectively located on both sides of the water tank 1, and the outlet pipe 4 is located obliquely above the inlet pipe 3. The outlet pipe 4 is located obliquely above the inlet pipe 3, so that the medium in the pipeline enters the water tank 1 through the inlet pipe 3 and is discharged outward from the outlet pipe 4. When the medium flows into the water tank 1 from the lower end and passes through the interior, it can be ensured that the medium fully contacts the thermometer 2, thereby obtaining accurate temperature measurement.

[0019] By setting up the water outlet pipe 4 and the water inlet pipe 3 distributed up and down to connect with the water tank 1, the order of medium inflow and outflow is strictly controlled so that the medium flows into the lower end of the detection box and flows out from the upper end, which helps to transfer heat to the thermometer 2 stably and evenly, thereby improving the measurement accuracy.

[0020] Working principle:

[0021] When in use, the drain valve of the external closed system or pipeline is inserted into the water inlet pipe 3, and the valve is opened. The medium in the external pipeline enters the water storage tank 1 through the water inlet pipe 3 and gathers at the bottom of the water storage tank 1. The medium in the water storage tank 1 is continuously detected by the detection end of the thermometer 2;

[0022] As the external medium is continuously injected, the liquid level of the medium in the water storage tank 1 gradually rises and is eventually discharged to the outside through the outlet pipe 4 .

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
