Description

Technical Field

[0001] The utility model belongs to the technical field of metrological detection equipment, and particularly relates to a metrological pressure probe with a temperature measuring device. Background Art

[0002] A metrological pressure probe is a sensor device used to measure pressure. Its main function is to convert pressure changes into electrical signals for output. A metrological pressure probe usually consists of a sensing element, a signal processing circuit, and an output interface. It can accurately measure pressure values within different ranges and convert the measurement results into standard signals for output, such as current signals or digital signals, for data recording or use in an automatic control system. The application of a temperature sensor inside the metrological pressure probe can provide important auxiliary information. Temperature changes can affect the output of the pressure sensor because the sensitivity and performance of the sensor may vary with temperature. The built-in temperature sensor can help measure and compensate for this effect, thereby improving the accuracy and stability of pressure measurement.

[0003] However, when installing a temperature sensor in the existing metrological pressure probe, a threaded method is usually used for fixation. After long-term use, the threads are prone to loosening, resulting in a decrease in the connection sealing performance between the installed temperature sensor and the metrological pressure probe, causing inaccurate temperature detection and affecting the compensation and adjustment of data, which is very inconvenient to use.

[0027] In order to further elaborate on a metering pressure probe with a temperature measuring device according to the present utility model and achieve the intended invention purpose, the following details the specific implementation manner, structure, features, and effects of a metering pressure probe with a temperature measuring device proposed according to the present utility model in combination with preferred embodiments. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0028] The following will further introduce in detail a metering pressure probe with a temperature measuring device according to the present utility model in combination with specific embodiments:

[0029] As Figures 1 to 4 shown, an embodiment of the present utility model provides a metering pressure probe with a temperature measuring device, and the metering pressure probe includes:

[0030] A pressure probe 1, with a first connecting pipe 1-1 communicating with the bottom of the pressure probe 1;

[0031] An installation pipe 2, with one side of the installation pipe 2 communicating with the pressure probe 1 and two opposite guiding grooves 2-1 opened on the other side; a clamping groove 2-2 is opened inside the guiding groove 2-1; a limiting shell 3 is arranged around the installation pipe 2;

[0032] A fixing component, including: an installation column 5 and a fixing pin 6; the fixing pin 6 is fixedly connected to the top and bottom of the middle section of the installation column 5; the fixing component is arranged on the other side of the installation pipe;

[0033] A temperature sensing probe 4, fixedly connected to one side of the installation column 5 and arranged on one side of the installation pipe 3.

[0034] In the technical solution provided by the embodiment of the present utility model, the pressure probe 1 is a pressure probe body for measuring pressure. The temperature sensing probe 4 is used to detect temperature changes and is fixedly connected to one side of the installation column 5. The outer diameter of the installation column 5 is smaller than the inner diameter of the installation pipe 2. When the installation column 5 is connected to the installation pipe 2, the temperature sensing probe 4 is inserted into the installation pipe 2. The installation column 5 is fixedly connected to the installation pipe 3 through the fixing pin 6. The specific process is as follows: After the two fixing pins 6 are respectively inserted into the guiding grooves 2-1, they are inserted into the clamping groove 2-2 based on the guiding action of the guiding grooves 2-1 (the clamping groove 2-2 communicates with the guiding grooves 2-1, and in this embodiment, the clamping groove 2-2 and the guiding grooves 2-1 are in a U shape, and the parallel parts of the U shape are the clamping groove 2-2 and part of the guiding grooves 2-1, and the length of the clamping groove 2-2 is shorter than the length of the parallel part of the guiding grooves 2-1), and then the limiting shell 3 abuts against the fixing pin 6 and is fixed in the clamping groove 2-2 to improve the installation stability of the temperature sensing probe 4.

[0035] As a preferred embodiment of the above, the temperature sensing probe 4 uses a thermistor sensor. In this embodiment, the temperature sensing probe 4 is further limited to using a thermistor sensor. Compared with other sensor types (such as RTDs and thermocouples), thermistors have higher sensitivity and can respond to temperature changes more quickly. This is particularly beneficial for applications that require rapid monitoring of temperature changes. The resistance characteristics of thermistors generally exhibit good linearity within their operating range, which makes temperature measurement results more accurate and reliable. At the same time, thermistors are also highly stable and can maintain relatively consistent performance during long-term use. The built-in temperature sensor can help measure and compensate for the effects of temperature differences, thereby improving the accuracy and stability of the pressure probe 1 body measurement.

[0036] As a preferred embodiment of the above, the stopper housing 3 is threadedly connected to the mounting tube 2. In this embodiment, the stopper housing 3 is further threadedly connected to the mounting tube 2. In this embodiment, the mounting tube 2 is provided with external threads 2-3, which overlap with the slot 2-2. When the stopper housing 3 is rotated, the external threads 2-3 act to tighten the stopper housing 3 against the fixing pin 6, preventing the fixing pin 6 from shaking and improving the stability of the temperature sensor 4 installation.

[0037] As a preference of the above embodiment, the other side of the pressure probe 1 is connected to a second connecting pipe 1 - 2 , and the surface of the second connecting pipe is provided with an external thread.

[0038] As a preferred embodiment of the above, the other side of the mounting post is fixedly connected to a fixing plug 7. In this embodiment, the mounting post 5 is further defined, and the fixing plug 7 is used to rotate the mounting post 5 so that the fixing pin 6 can be more easily inserted into the slot 8, thereby making it easier to connect the mounting post 5 to the mounting tube 2.

[0039] As a further preferred embodiment of the above, the fixing assembly further includes a reset ring 8, which is sleeved on the mounting post 5 and located between the fixing pin 6 and the fixing plug 7. In this embodiment, the fixing assembly is further defined, and the reset ring 8 is sleeved on the mounting post 5 and is slidably connected to the mounting post 5.

[0040] As a further preferred embodiment of the above embodiment, the fixing assembly further includes a spring 9, which is sleeved onto the mounting post 5 and fixedly connected at both ends to the reset ring 8 and the fixing plug 7. This embodiment further defines the fixing assembly, wherein the spring sleeve 8 is sleeved onto the mounting post 5 and fixedly connected at both ends to the reset ring 8 and the fixing plug 7. The compression energy storage function of the spring 8 provides elastic support for the fixing plug 7, further preventing the fixing pin 6 from shaking and improving the stability of the temperature sensor 4.

[0041] As a further preference of the above embodiment, the fixing assembly further includes a plurality of sealing rings 10, which are fixedly connected to the surface of the mounting post 5 and are arranged around one side of the mounting post 5 where the temperature sensing probe 4 is connected. In this embodiment, the fixing assembly is further defined. On one side of the mounting post 5 where the temperature sensing probe 4 is connected, between the temperature sensing probe 4 and the fixing pin 6, a plurality of sealing rings 10 are fixedly connected around the surface of the mounting post 5. The sealing rings 10 can be selectively arranged at the edge of the mounting post 5.

[0042] As a further preference of the above embodiment, a movable groove 7-1 is formed on one side of the fixing plug 7, a rotating shaft 7-2 is fixedly connected inside the movable groove 7-1, and a movable ring 7-3 is sleeved on the surface of the rotating shaft 7-2. In this embodiment, the formation of the movable groove 7-1 on the fixing plug 7 is further defined. The rotating shaft 7-2 is fixedly connected inside the movable groove 7-1, and the movable ring 7-3 is sleeved on the surface of the rotating shaft 7-2. The arrangement of the movable ring 7-3 in this embodiment makes it more convenient to control the fixing plug 7.

[0043] As a further preference of the above embodiment, a first magnet 7-4 is fixedly connected to the surface of the movable ring 7-3, a second magnet 7-5 is fixedly connected inside the movable groove 7-1, and the first magnet 7-4 and the second magnet 7-5 have opposite magnetic poles. In this embodiment, the magnets are further defined to be arranged on the surface of the movable ring 7-3 and inside the movable groove 7-1. By arranging magnets with opposite magnetic poles on the surface of the movable ring 7-3 and inside the movable groove 7-1, the movable ring 7-3 can be adsorbed and fixed.

[0044] The working principle of the present utility model is as follows: First, the staff manually rotates the mounting post 5 to align the fixing pin 6 with the guiding groove 2-1, and then pushes the fixing plug 7. The fixing plug 7 cooperates with the mounting post 5 to drive the reset ring 8 into contact with the mounting tube 2 and compress the spring 9. While the mounting post 5 moves, it drives the temperature sensing probe 4 to insert into the mounting tube 2. Then, when the fixing pin 6 is inserted to the bottom of the guiding groove 2-1, the fixing plug 7 is rotated clockwise to drive the mounting post 5 to rotate the fixing pin 6 and make it fit against the inner wall of the card slot 2-2. After that, the fixing plug 7 is released, and the spring 9 will reset the fixing plug 7 and the mounting post 5, so that the fixing pin 6 is completely inserted into the card slot 2-2, completing the rapid installation of the temperature sensing probe 4. At the same time, the entire operation of the fixing plug 7 can be completed through the movable ring 7-3. Finally, after the movable ring 7-3 of the fixing plug 7 is released, the movable ring 7-3 automatically adsorbs to the magnet on the movable groove 7-1. Finally, the limiting shell 3 is rotated, and through the external thread 2-3 on the surface of the mounting tube 2, the limiting shell 3 is pressed against the fixing pin 6 to prevent the fixing pin 6 from shaking, which can improve the installation stability of the temperature sensing probe 4.
