[0038] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0039] Reference Figures 1-3 As shown in the figure, this utility model embodiment proposes a petrochemical temperature measuring device, including a valve body 1, a valve core 2, a packing 3, an actuator 4, a mounting tube 5, and a thermometer 6, wherein:

[0040] The valve body 1 is used to connect to the storage tank, and the valve body 1 is provided with a valve hole 11;

[0041] The valve core 2 is slidably installed in the valve hole 11, and the valve core 2 extends into the medium stored in the storage tank;

[0042] The packing 3 fills the valve hole 11 and is located between the valve core 2 and the inner wall of the valve hole 11. The packing 3 is self-lubricating. The packing 3 has a double layer to improve the sealing effect and ensure the reliability of the seal.

[0043] The actuator 4 is mounted on the valve body 1 and connected to the valve core 2; the actuator 4 drives the valve core 2 to move along the axial direction;

[0044] The mounting tube 5 is obliquely inserted into the valve core 2. The mounting tube 5 is obliquely connected to the valve core 2 so that the mounting tube 5 does not extend beyond the maximum circumferential space of the valve body 1, making the device itself more compact and easier to install and arrange. In this embodiment, the angle between the mounting tube 5 and the valve core 2 is 10°. Of course, this angle can be set as needed.

[0045] The thermometer 6 is installed at the end of the mounting tube 5 away from the valve core 2.

[0046] The petrochemical temperature measuring device proposed in this embodiment drives the valve core 2 to slide along the valve hole 11 via the actuator 4. The valve core 2 extends into the medium stored in the storage tank. The mounting tube 5 is obliquely connected to the valve core 2, and the thermometer 6 is installed at the end of the mounting tube 5 away from the valve core 2. The valve core 2 transmits the medium temperature sequentially to the mounting tube 5 and the thermometer 6. The thermometer 6 does not directly contact the medium, avoiding shortening the sensor life due to direct contact, reducing replacement frequency, and lowering maintenance costs. The thermometer 6 moves with the valve core 2, allowing it to measure the temperature at different locations, covering a large area, and achieving global monitoring.

[0047] In some embodiments, the petrochemical temperature measuring device further includes a guide sleeve 7, which is installed in the valve hole 11. The guide sleeve 7 has a guide hole 71 along the axial direction, and the valve core 2 is slidably installed in the guide hole 71. The guide hole 71 guides the sliding of the valve core 2, and the guide sleeve 7 can guide and stabilize the valve core 2, enabling it to operate smoothly and improving the stability of the device.

[0048] In some embodiments, since the valve core 2 needs to extend into the medium, the medium may form scale and solidify on the outer wall of the valve core 2, creating foreign matter that adheres to the outer wall of the valve core 2. To avoid the scale and solidified foreign matter causing the valve core 2 to slide and become stuck, the following solution is designed: The petrochemical temperature measuring device further includes an annular scraper 8, which is installed in the valve hole 11 and used to scrape off the scale and solidified foreign matter on the peripheral wall of the valve core 2 during its movement. The annular scraper 8 fits against the outer wall of the valve core 2, scraping off the scale and solidified foreign matter on the peripheral wall of the valve core 2 during its movement, preventing the valve core 2 from getting stuck during its movement in the valve hole 11, improving reliability, and guiding and stabilizing the valve core 2, further enabling it to operate smoothly.

[0049] In some embodiments, the actuator 4 includes a mounting bracket 41 and a cylinder 42. The mounting bracket 41 is bolted to the valve body 1, and the cylinder 42 is mounted on the mounting bracket 41, with its output shaft connected to the valve core 2. The output shaft of the cylinder 42 extends and retracts, thereby driving the valve core 2 to descend and rise, completing the temperature measurement of the medium at different depths.

[0050] In some embodiments, the petrochemical temperature measuring device further includes a connecting block 9, which is connected to the output shafts of the valve core 2 and the cylinder 42 respectively. The connection between the valve core 2 and the cylinder 42 is achieved through the connecting block 9, eliminating the need for the output shafts of the valve core 2 and the cylinder 42 to be coaxial, thus improving installation convenience and ensuring a more convenient and reliable connection.

[0051] In some embodiments, the petrochemical temperature measuring device further includes a scale bar 10 and a pointer 20. The scale bar 10 is mounted on the mounting bracket 41 and parallel to the axial direction of the valve core 2. The pointer 20 is mounted on the connecting block 9, with its end pointing to a scale line on the scale bar 10. The pointer 20 moves with the connecting block 9 and the valve core 2. During the movement, the end of the pointer 20 points to a scale line on the scale bar 10, which can clearly indicate the height at which the valve core 2 rises and falls, thereby determining the medium temperature at different heights and improving the convenience of recording measurement data.

[0052] In some embodiments, the petrochemical temperature measuring device further includes a pressure cap 30, which is installed on the valve body 1 and abuts against the packing 3. The pressure cap 30 extends into the valve hole 11 and abuts against the packing 3. Then, the pressure cap 30 and the valve body 1 are fastened together by bolts to achieve compaction and sealing of the packing 3 and improve the sealing effect.

[0053] In some embodiments, the valve core 2 is provided with a blind hole 21, the end of which is closed and extends into the medium. The blind hole 21 extends from the end of the valve core 2 near the actuator 4 to the end of the valve core 2 away from the actuator 4. This hollow design of the valve core 2 can improve thermal conductivity and enhance the accuracy of temperature measurement data.

[0054] The working principle of the petrochemical temperature measuring device in this embodiment is as follows: the actuator 4 drives the valve core 2 to slide along the valve hole 11. The valve core 2 extends into the medium stored in the storage tank. The mounting tube 5 is obliquely connected to the valve core 2. The thermometer 6 is installed at the end of the mounting tube 5 away from the valve core 2. The valve core 2 transmits the medium temperature sequentially to the mounting tube 5 and the thermometer 6. The thermometer 6 does not directly contact the medium, avoiding shortening the sensor life due to direct contact, reducing the replacement frequency, and lowering maintenance costs. The thermometer 6 moves with the valve core 2, which can measure the temperature at different locations, covering a large area and realizing global monitoring. The annular scraper 8 is attached to the outer wall of the valve core 2. During the movement of the valve core 2, it scrapes off the scale and solidified foreign matter on the peripheral wall of the valve core 2, preventing the valve core 2 from getting stuck during the movement in the valve hole 11, improving reliability, and guiding and stabilizing the valve core 2, further enabling it to operate smoothly.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
