Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring equipment technology, specifically to a rapid-loading temperature, pressure, and flow detection probe. Background Technology

[0002] In the fields of industrial production and environmental monitoring, accurate measurement of temperature, pressure, and flow is crucial. Traditional temperature, pressure, and flow detection devices typically employ independent sensor components, such as temperature sensors and pressure sensors. These devices have certain limitations in installation and use. For example, different types of sensors need to be installed separately, which not only increases the difficulty and cost of installation but also makes sensor installation and maintenance more difficult in complex or confined working environments. Furthermore, traditional devices often fail to meet requirements for sealing and stability when facing harsh conditions such as high temperature and high pressure.

[0003] Inadequacy of existing technology

[0004] 1. Low integration: Most existing detection equipment is designed for a single function, meaning that each parameter (temperature, pressure, flow rate) requires a separate sensor, resulting in a large overall size of the equipment and inconvenient installation, especially in space-constrained situations such as inside a flue, where this defect is particularly obvious.

[0005] 2. Poor sealing performance: When working in extreme environments such as high temperature and high pressure, the sealing performance of traditional detection devices is often poor, which can easily cause leakage, affect measurement accuracy, and may even lead to safety accidents.

[0006] 3. Limited adjustment flexibility: For some application scenarios that require adjustment of the detection position or angle according to the actual working conditions, traditional equipment often lacks an effective adjustment mechanism. Once installed, it is very inconvenient to adjust the angle, which limits its application range.

[0007] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0008] To address the problems existing in the prior art, this utility model provides a rapid-loading temperature, pressure, and flow detection probe.

[0009] To achieve the above objectives, the specific solution of this utility model is as follows:

[0010] This utility model provides a rapid loading temperature, pressure, and flow detection probe, comprising:

[0011] Total pressure tube, back pressure tube, temperature sensor, outer tube, mounting base;

[0012] The mounting base is provided with a first channel and a second channel;

[0013] The full pressure pipe and the back pressure pipe are respectively installed in the first channel and the second channel;

[0014] The front openings of the full pressure tube and the back pressure tube are arranged back to back with opposite directions.

[0015] The temperature sensor is installed inside the temperature sensor sleeve on the mounting base;

[0016] The outer sleeve is fitted over the outside of the total pressure tube, the back pressure tube, and the temperature sensor. One end of the outer sleeve is mounted on the mounting base, and the other end is provided with a front sealing plate.

[0017] The front ends of the full pressure pipe and the back pressure pipe extend out from the front sealing plate (the front ends of the full pressure pipe, the back pressure pipe, and the temperature sensor extend into the chimney for detection).

[0018] Furthermore, the mounting base is provided with a first opening and a second opening that communicate with the first channel and the second channel, respectively;

[0019] The mounting base is provided with a first annular groove and a second annular groove corresponding to the first opening and the second opening, respectively.

[0020] Furthermore, the mounting base is disposed in the measuring cavity, which is provided with a full pressure channel and a back pressure channel;

[0021] The first annular groove and the second annular groove are respectively connected to the full pressure channel and the back pressure channel, so that the rotation angle of the mounting base in the measuring cavity can also ensure that the first annular groove and the second annular groove are connected to the full pressure channel and the back pressure channel respectively.

[0022] Furthermore, a sealing gasket, a first sealing ring, and a second sealing ring are also installed on the outer wall of the mounting base for sealing between the mounting base and the measuring cavity;

[0023] The sealing gasket and the first sealing ring are located on both sides of the first annular groove; the first sealing ring and the second sealing ring are located on both sides of the second annular groove.

[0024] Furthermore, a rear sealing shaft is also provided at the rear end of the mounting base;

[0025] The rear sealing shaft is located outside the measuring cavity. The rear sealing shaft is used to rotate the mounting base, thereby changing the angle of the full pressure tube and the back pressure tube mounted on the mounting base.

[0026] Furthermore, a plurality of screws are arranged around the mounting base on the measuring cavity, and the heads of the screws are used to press the mounting base;

[0027] Loosen the screw, rotate the mounting base to the corresponding detection angle via the rear sealing shaft, and then tighten the screw. The head of the screw presses against the mounting base to secure it.

[0028] Furthermore, the full pressure pipe, back pressure pipe, outer sleeve, and mounting base are sealed and welded together.

[0029] The front sealing plate is sealed and welded to the outer sleeve;

[0030] The full pressure pipe, back pressure pipe and front sealing plate are sealed and welded together.

[0031] Furthermore, the first and second sealing rings are made of high-temperature resistant fluororubber.

[0032] The technical solution of this utility model has the following beneficial effects:

[0033] 1. High integration:

[0034] This invention's quick-load temperature, pressure, and flow detection probe integrates the total pressure tube, back pressure tube, and temperature sensor onto a single mounting base, reducing the overall size of the device and improving ease of installation and use. Especially in space-constrained environments, such as inside flues, this design significantly reduces installation difficulty and cost.

[0035] 2. Excellent sealing performance:

[0036] The total pressure tube, back pressure tube, outer tube, and mounting base are sealed by welding to ensure airtightness under high temperature and high pressure environments. The front sealing plate is also sealed by welding to the outer tube, total pressure tube, and back pressure tube, further enhancing the probe's sealing performance, preventing leakage, and improving measurement accuracy and safety.

[0037] 3. Flexible angle adjustment:

[0038] The mounting base has a rear sealing shaft at its tail, which can be rotated to adjust the angle of the total pressure tube and the back pressure tube. Screws on the measuring chamber can be loosened to release the mounting base, adjusted to the desired angle, and then tightened again to secure it. This design allows the probe to adapt to different testing needs, improving the applicability and flexibility of the equipment.

[0039] 4. Reliable connection and sealing:

[0040] The mounting base is provided with a first annular groove and a second annular groove, which are respectively connected to the full pressure channel and the back pressure channel in the measuring chamber. Even if the mounting base rotates in the measuring chamber, it can maintain communication with the full pressure channel and the back pressure channel. A sealing gasket, a first sealing ring and a second sealing ring are also installed on the outer wall of the mounting base. These sealing elements are located on both sides of the annular groove, ensuring the sealing performance between the mounting base and the measuring chamber.

[0041] 5. High-temperature resistant materials:

[0042] The first and second sealing rings are made of high-temperature resistant fluororubber material, which can maintain good sealing performance in high-temperature environments, extend the service life of the probe, and improve the reliability and stability of the equipment.
