Description

Technical Field

[0001] This utility model relates to the field of transmitter technology, specifically a temperature transmitter. Background Technology

[0002] The temperature transmitter uses thermocouples and resistance temperature detectors (RTDs) as temperature sensing elements. The output signal from the temperature sensing element is sent to the transmitter module. After processing by circuits such as voltage regulation and filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection, it is converted into a 4-20mA current signal or a 0-5V / 0-10V voltage signal that is linearly related to the temperature and is output as a digital signal.

[0003] Among the publicly disclosed authorized patents, Chinese patent number CN201720274914.6 discloses a temperature transmitter designed to prevent water hammer. The technical problem is that water hammer causes the measuring end of the temperature transmitter to oscillate, resulting in bending; high-temperature environments also reduce the lifespan of electronic components. The technical solution is: this invention sets the measuring end of the temperature transmitter in a rhomboid shape, reducing the pressure impact of water hammer on the internal measuring end of the pipe, preventing bending of the measuring end, and rapidly dissipating upward-conducted heat through the heat sink, insulation plate, and coolant in the cooling shell, thus extending the lifespan of the electronic components.

[0004] In the aforementioned device, to address the water hammer effect inside the pipeline, which can damage the transmitter, a rhombus shape is designed on the outside of the measuring end to improve the stability of the detection end and reduce water pressure. However, since the device is located inside the pipeline, it is impossible to precisely fix the installation position of the monitoring end. When the side of the rhombus is perpendicular to the direction of the water pipe, the water flow will come into contact with the rhombus surface when flowing inside the pipeline, thus failing to activate the function of reducing water pressure. Therefore, we propose a temperature transmitter. Utility Model Content

[0005] To address the shortcomings of existing temperature transmitters, this invention provides a temperature transmitter with the following features: a flow divider is fitted onto the outside of the pipe sleeve. When water flows in different directions inside the pipe, the flow divider rotates under negative pressure, with one corner of the flow divider aligned with the water flow direction. Simultaneously, the two sides of the flow divider can depressurize the water flow, thereby reducing water pressure damage to the pipe sleeve. This solves the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a temperature transmitter, including a water pipe, an installation sleeve is movably fitted inside the water pipe, a pipe sleeve is fixedly connected to the lower end of the installation sleeve, a diamond-shaped sleeve is fixedly connected to the inner wall of the installation sleeve, a connecting rod is movably fitted inside the upper end of the installation sleeve, a transmitter body is installed at the top of the connecting rod, a lower mounting plate is fixedly connected to the lower part of the pipe sleeve, a telescopic sleeve is fitted to the lower end of the lower mounting plate, an arc-shaped plate is installed at the lower end of the telescopic sleeve, a spring is installed between the lower mounting plate and the arc-shaped plate, an installation plate is fixedly connected to the outside of the connecting rod, an upper mounting pad is movably fitted to the outside of the connecting rod, and a threaded sleeve is fixedly connected to the lower part of the upper mounting pad, a sealing pin is movably fitted inside the front end of the upper mounting pad, a sealing sleeve is fitted outside the sealing pin, a connecting sleeve is fitted to the lower end of the pipe sleeve, a flow divider plate is fixedly connected to the top of the connecting sleeve, and a sealing gasket is fitted outside the installation sleeve.

[0007] Preferably, the rhomboid sleeve is rhomboid in shape, and the rhomboid sleeve is movably fitted inside the lower end of the connecting rod, with the mounting plate and the top of the mounting sleeve fitting together.

[0008] Preferably, the sealing pin is movably sleeved inside the connection between the two sets of upper mounting pads, and the threaded sleeve is threadedly connected to the top of the mounting sleeve and the outside of the mounting plate.

[0009] Preferably, the sealing gasket is installed between the mounting sleeve and the water pipe, and the mounting sleeve and the water pipe are threaded together.

[0010] Preferably, a thermometer is installed inside the sleeve, and the thermometer is connected to the transmitter body via a wire.

[0011] Preferably, the connecting sleeve is installed at both ends of the splitter plate, and the splitter plate is triangular.

[0012] Preferably, the lower end of the arc-shaped plate contacts the interior of the water pipe, while the spring is installed between the lower mounting plate and the arc-shaped plate.

[0013] Compared with existing temperature transmitters, this invention has the following advantages:

[0014] 1. This temperature transmitter has a circular sleeve installed inside the water pipe. A flow divider plate with a triangular shape is fitted around the outside of the sleeve. When the water flow impacts the outside of the flow divider plate, the angle of the flow divider plate changes with the flow of water. The flow divider plate also divides the water flow. Therefore, when water flows from different directions, the flow divider plate can divide the water flow and improve the protection of the sleeve.

[0015] 2. This temperature transmitter is limited by the interlocking of the mounting sleeve and the connecting rod. After the upper mounting pad is fitted onto the upper end of the mounting plate, the upper mounting pad is spliced ​​and fixed by the sealing pin. At the same time, the threaded sleeve and the mounting plate move with each other, thereby improving the sealing between the mounting sleeve and the connecting rod. Meanwhile, the sealing sleeve is controlled to be fitted onto the outside of the water pipe, which can then drive the upper mounting pad to tighten downwards and fix it, thereby driving the entire device to be installed outside the water pipe, improving the stability of the detection equipment during installation.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A temperature transmitter includes a water pipe 1, with a mounting sleeve 2 movably fitted inside the water pipe 1. The positions of the water pipe 1 and the mounting sleeve 2 are mutually defined by splicing. A pipe sleeve 3 is fixedly connected to the lower end of the mounting sleeve 2, and the pipe sleeve 3 drives a thermometer to limit the position. A diamond-shaped sleeve 4 is fixedly connected to the inner wall of the mounting sleeve 2, and the diamond-shaped sleeve 4 is snapped into the inside of a connecting rod 5 to improve the stability during installation. A connecting rod 5 is movably fitted inside the upper end of the mounting sleeve 2, and a transmitter body 11 is installed at the top of the connecting rod 5. The transmitter body 11 drives the display of the detection result. A lower mounting plate 12 is fixedly connected to the lower part of the pipe sleeve 3. A telescopic sleeve 15 is fitted to the lower end of the lower mounting plate 12, and an arc-shaped plate 16 is installed at the lower end of the telescopic sleeve 15. A spring 17 is installed between the lower mounting plate 12 and the arc-shaped plate 16. When the pipe sleeve 3 is installed inside the water pipe 1, the arc-shaped plate 16 moves downward under the elastic action of the spring 17. To improve the stability of the pipe sleeve 3 during installation, an mounting plate 6 is fixedly connected to the outside of the connecting rod 5, and an upper mounting pad 8 is movably sleeved on the outside of the connecting rod 5. A threaded sleeve 7 is fixedly connected to the lower part of the upper mounting pad 8. The threaded sleeve 7 limits the space between the mounting sleeve 2 and the mounting plate 6. A sealing pin 9 is movably sleeved inside the front end of the upper mounting pad 8. The sealing pin 9 drives the two sets of upper mounting pads 8 to be spliced ​​and fixed. A sealing sleeve 18 is sleeved on the outside of the sealing pin 9. The sealing sleeve 18 drives the upper mounting pad 8 to be compressed and fixed downwards. A connecting sleeve 13 is sleeved on the lower end of the outside of the pipe sleeve 3. A diverter plate 14 is fixedly connected to the top of the connecting sleeve 13. The angle of the diverter plate 14 changes under the impact of water flow. At the same time, the diverter plate 14 diverts the water flow to both sides, reducing the impact force of the water flow on the pipe sleeve 3. A sealing gasket 10 is sleeved on the outside of the mounting sleeve 2. The sealing gasket 10 improves the sealing performance of the mounting sleeve 2 during installation.

[0025] Please see Figure 5 The rhomboid sleeve 4 is rhomboid in shape and is movably fitted inside the lower end of the connecting rod 5. The mounting plate 6 and the top of the mounting sleeve 2 are in close contact with each other. The rhomboid sleeve 4 is rhomboid in shape. At the same time, when the connecting rod 5 is installed on the upper part of the mounting sleeve 2, the position between the mounting sleeve 2 and the connecting rod 5 is limited by the rhomboid sleeve 4, thereby improving the sealing between the sleeve 3 and the connecting rod 5.

[0026] Please see Figure 3 The sealing pin 9 is movably sleeved inside the connection between the two sets of upper mounting pads 8. The threaded sleeve 7 is threadedly connected to the top of the mounting sleeve 2 and the outside of the mounting plate 6. After the two sets of upper mounting pads 8 are sleeved on the upper part of the mounting plate 6, and the sealing pin 9 is installed between the two sets of upper mounting pads 8, the sealing pin 9 drives the position between the two sets of upper mounting pads 8 to be spliced ​​and limited. At the same time, the mounting plate 6 is rotated, and the mounting plate 6 drives the threaded sleeve 7 to rotate. Then the threaded sleeve 7 can drive the mounting sleeve 2 and the mounting plate 6 to perform threaded movement, thereby improving the stability of the connection rod 5 and the mounting sleeve 2 when they are installed together.

[0027] Please see Figure 5 The sealing gasket 10 is installed between the mounting sleeve 2 and the water pipe 1. The mounting sleeve 2 and the water pipe 1 are threaded together. The sealing gasket 10 is installed between the water pipe 1 and the mounting sleeve 2, thereby improving the sealing performance between the water pipe 1 and the mounting sleeve 2 and controlling the threaded movement between the mounting sleeve 2 and the water pipe 1, thus improving the ease of installation of the equipment mounting sleeve 2.

[0028] Please see Figure 1 A thermometer is installed inside the sleeve 3, and the thermometer is connected to the transmitter body 11 via a wire. The thermometer detects the temperature of the liquid flowing in the water pipe 1, and the thermometer is connected to the transmitter body 11 via a wire. The transmitter body 11 can display the detection results.

[0029] Please see Figure 4 The connecting sleeve 13 is installed at both ends of the flow divider 14. The flow divider 14 is triangular and is sleeved on the outside of the pipe sleeve 3. When there is water flow impact, the water flow will first contact the flow divider 14. The outside of the flow divider 14 is triangular. Then the flow divider 14 disperses the flowing liquid in the direction of water hammer. The direction of the flow divider 14 can be adjusted according to the direction of water hammer to avoid the water flow velocity being too fast, which would cause impact damage to the pipe sleeve 3.

[0030] Please see Figure 6 The lower end of the arc-shaped plate 16 contacts the inside of the water pipe 1, while the spring 17 is installed between the lower mounting plate 12 and the arc-shaped plate 16. The arc-shaped plate 16 is installed at the lower end of the lower mounting plate 12, and under the elastic force of the spring 17, it moves downwards, causing the spring 17 to contact the inner wall of the water pipe 1. This prevents the lower end of the sleeve 3 from shifting when it extends into the water pipe 1.

[0031] Working principle: During use, the sleeve 3 is installed inside the water pipe 1, and the lower end of the arc plate 16 is controlled to contact the inner wall of the water pipe 1. At the same time, a thermometer is installed inside the sleeve 3, and a connecting rod 5 is sleeved on the upper part of the mounting sleeve 2. The upper mounting pad 8 is used to limit the position between the mounting sleeve 2 and the sleeve 3. At the same time, under the impact of water flow, the diverter plate 14 inside the water pipe 1 returns to its initial state, and the inclined part on the outside of the diverter plate 14 is continuously in the direction of water flow, thereby ensuring that the diverter plate 14 is in contact with the direction of water flow. The diverter plate 14 drives the flow to split to both sides, reducing the problem of damage to the sleeve 3 under the action of water pressure.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
