Abstract
Description
Technical Field
[0001] This utility model relates to the field of resistance temperature detector (RTD) technology, and in particular to a flange sleeve type RTD. Background Technology
[0002] A flange-mounted resistance temperature detector (RTD) is a temperature sensor that combines a flange mounting structure with a protective sleeve design. It accurately measures the temperature of a medium by measuring changes in resistance value and is suitable for harsh conditions such as high pressure and corrosive environments. For example, a flange-mounted RTD disclosed in application number 202421178020.3 scrapes and cleans impurities adhering to the outer protective sleeve to prevent environmental impurities from adhering to the outer protective sleeve and reducing heat conduction efficiency, thereby affecting the normal temperature measurement of the RTD itself.
[0003] However, the above structure cannot effectively adjust the position of the connector during use, which makes it unsuitable for installation in different positions, reducing its installation efficiency and scope of application. Furthermore, it cannot provide effective protection and fit, reducing its temperature testing efficiency and usage efficiency. Therefore, we propose a flange sleeve type thermal resistor. Utility Model Content
[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a flange sleeve type thermal resistor that can effectively adjust the position of the connecting parts, thereby adapting to installation in different positions, improving its installation efficiency and application range, and providing effective protection and fit, thus improving its temperature testing efficiency and usage efficiency.
[0005] To achieve the above objectives, a flange-type resistance temperature detector (RTD) is provided, comprising: a RTD body, a fitting groove on the right side of the RTD body, a connecting rod fitting inside the fitting groove, an outer sleeve of the connecting rod, a threaded tube fitted around the RTD body near the right side, and a plurality of evenly distributed mating rods connected to the right side of the threaded tube by bolts, the right end of the mating rods being connected to the left side of the ring by bolts.
[0006] According to the flange sleeve type thermal resistor, a protective tube is sleeved on the main body of the thermal resistor near the left side, and sealing blocks are respectively sleeved on the left and right sides of the protective tube.
[0007] According to the flange sleeve type thermal resistor, a threaded hole is provided on the sealing block located on the right side, and an external thread matching the internal thread of the threaded tube is provided on the outer wall of the threaded tube.
[0008] According to the flange sleeve type thermal resistor, the outer wall of the protective tube is connected with a number of evenly distributed bonding tubes, and the outer wall of the protective tube is provided with a number of evenly distributed first insertion holes corresponding to the bonding tubes.
[0009] According to the flange sleeve type thermal resistor, the outer wall of the protective tube is connected to a number of evenly distributed bonding plates, and the outer wall of the bonding plates is provided with a number of evenly distributed second insertion holes.
[0010] According to the flange sleeve type thermal resistor, the two sealing blocks are arranged symmetrically about the central axis of the protective tube, and the sealing blocks are provided with perforations that match the thermal resistor body.
[0011] The above solution has at least one of the following beneficial effects: This technical solution, through the cooperation between components such as threaded pipe, connecting rod, ring plate and connecting rod, enables the effective adjustment of the position of the connector, thereby making it adaptable to installation in different positions, improving its installation efficiency and applicability, and providing effective protection and fit, thus improving its temperature testing efficiency and usage efficiency.

A threaded hole is formed on the right-side sealing block 7, and an external thread matching the internal thread of the threaded tube 2 is formed on its outer wall.
