Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline temperature measurement, and in particular relates to a pipeline temperature measurement element installation device. Background Art

[0002] When measuring the temperature of a pipeline, a pipeline temperature measuring device, such as a thermal resistor, a temperature transmitter or a bimetallic thermometer, usually inserts the probe of the temperature measuring device into the pipeline, and the base of the temperature measuring device is threadedly connected to the pipe clamp on the pipeline or the carbon steel base set on the pipeline, and the threads are wrapped with raw tape to prevent liquid leakage in the pipeline.

[0003] However, in the heating field and in humid high-temperature and high-pressure environments, after a period of use, the base will rust, run, bubble, drip, and leak. The probe of the temperature measuring device is easily corroded by the liquid in the pipeline, which poses a great safety hazard under high temperature and high pressure conditions. If the probe is damaged during operation, either it is not replaced and operated with the problem, or it is shut down and drained to replace the temperature measuring device. Shutdown and draining will affect production. In addition, the size of the base on the existing pipeline corresponds to the size of the base of the temperature measuring device. If a different model of temperature measuring device is replaced, the base on the original pipeline cannot adapt to the base of the different model of temperature measuring device. The original base needs to be removed and a new pipeline base that matches the base of the newly replaced temperature measuring device needs to be set, which makes the replacement efficiency low.

[0018] In the figure: 1 is a stainless steel joint, 2 is a water-stop pad, 3 is a stainless steel base, 4 is a stainless steel pipe, 5 is a stainless steel plug, 6 is a bolt, 7 is a rubber cylindrical pad, 8 is a stainless steel joint installation groove, and 9 is a through hole. DETAILED DESCRIPTION

[0019] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0020] like Figure 1-2As shown, the utility model provides a pipeline temperature measuring element installation device, including a stainless steel joint 1 and a stainless steel pipe 4. The stainless steel joint 1 is fixedly connected to the stainless steel pipe 4. The stainless steel pipe 4 is provided with a stainless steel plug 5 at one end away from the stainless steel joint 1. Specifically, the stainless steel joint 1, the stainless steel pipe 4 and the stainless steel plug 5 are an integrated structure. They can be welded into an integrated structure or cast into an integrated structure, so that the connection between them is a leak point. The use of stainless steel is conducive to temperature conduction, prevents corrosion, and improves service life.

[0021] The stainless steel joint 1 is provided with a probe jack for the temperature measuring element, and the interior of the whole formed by the stainless steel joint 1, the stainless steel tube 4, and the stainless steel plug 5 is provided with a receiving groove matching the probe of the temperature measuring element. Since the internal space of the stainless steel joint 1, the stainless steel tube 4, and the stainless steel plug 5 of the utility model only matches the probe size of the temperature measuring element. Since the base sizes of different types of temperature measuring elements vary, but the size of the probe of the temperature measuring element is a specified size, when replacing the temperature measuring element, it is only necessary to replace the temperature measuring element with a probe of the same size, thereby avoiding the situation where the entire mounting base needs to be replaced when replacing the temperature measuring element.

[0022] The pipeline temperature measuring element installation device of the utility model also includes a stainless steel base 3, which is sealed and fixedly connected to the pipeline, and can be specifically welded. The stainless steel joint 1 is sealed and fixedly connected to the stainless steel base 3, and can be specifically threadedly connected to the stainless steel base 3, and is fastened and sealed by a water stop pad 2. After the stainless steel base 3 is assembled with the pipeline, the stainless steel pipe 4 extends into the pipeline from one-half to two-thirds to ensure that the stainless steel pipe 4 can contact the liquid inside the pipeline.

[0023] Specifically, the stainless steel base 3 is provided with a stainless steel joint installation groove 8 at one end close to the stainless steel joint 1, and the installation surfaces of the stainless steel joint 1 and the stainless steel base 3 are a plane after being assembled. The connection between the stainless steel joint 1 and the stainless steel base 3 is provided with a water stop pad 2, which can be a copper pad, to prevent water leakage.

[0024] Specifically, a through hole 9 for the limiting device to pass through is opened on the side of the stainless steel joint 1. The limiting device is assembled in the through hole 9 to limit the probe of the temperature measuring element inserted into the stainless steel joint 1 and the stainless steel pipe 4. Figure 2 As shown, the limiting device can be a bolt 6, and the through hole 9 opened on the side of the stainless steel joint 1 is a screw hole matching the bolt 6. The end of the bolt 6 close to the temperature measuring element probe is provided with a rubber cylindrical pad 7. The bolt 6 is assembled in the through hole 9, and the rubber cylindrical pad 7 is pressed against the temperature measuring element probe for limiting. The temperature measuring element probe is fixed and loosened by adjusting the bolt 6, which is easy to operate and convenient to use.

[0025] When in use, insert the probe of the temperature measuring element into the receiving groove surrounded by the stainless steel joint 1, stainless steel pipe 4, and stainless steel plug 5, so that the probe contacts the stainless steel joint 1, stainless steel pipe 4, and stainless steel plug 5, and adjust the bolt 6 to fix the probe of the temperature measuring element. Since the probe of the temperature measuring element contacts the stainless steel pipe 4 and stainless steel plug 5, and the stainless steel pipe 4 and stainless steel plug 5 contact the liquid in the pipeline, the temperature measurement purpose is achieved. When replacing the temperature measuring element, just loosen the bolt 6 and replace the temperature measuring element with a probe of the same size, without stopping the operation and draining the water to avoid affecting production.
