Technical Field

[0001] This utility model relates to the field of pressure detection technology, specifically a pressure probe with temperature detection function. Background Technology

[0002] A pressure probe, also known as a pressure sensor or pressure transmitter, is an instrument used to detect the pressure of liquids or gases. It converts the sensed pressure into electrical signals, which can be read, displayed, or further processed by a data acquisition system.

[0003] The publication number CN223179578U provides a pressure probe with temperature detection function, including: a pressure sensor, a support tube, a sealing assembly, and a connecting tube.

[0004] The aforementioned pressure probe addresses the lack of sealing detection functionality in existing pressure probes. However, when installing temperature sensors, the probe length varies for different specifications, causing the detection end to shift and affecting temperature detection. It is inconvenient to adjust to accommodate probes of different lengths. Furthermore, during pressure sensor assembly and disassembly, the internal medium is prone to leakage under pressure, making automatic sealing difficult. Utility Model Content

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.

[0018] Example 1 Combination Figures 1-4 A pressure probe with temperature detection function includes a pressure sensor 1 and a temperature sensor 2.

[0019] See Figure 2 Furthermore, the adjustment mechanism 4 includes a detection tube 6, which is fixedly installed on the outside of the connecting seat 3. A screw tube 7 is connected inside the detection tube 6. A first screw groove 8 is opened at the outer end of the screw tube 7. Several slots 9 are opened on the outer wall of the screw tube 7 near the outer end. A pressure plate 10 is movably installed on the outer side of the screw tube 7. Several locking blocks 11 are fixedly installed on the outer side of the pressure plate 10. A fixed plate 12 is fixedly installed on the outside of the detection tube 6. Four guide rods 13 penetrate the interior of the fixed plate 12 and are connected to the pressure plate 10. A first spring 14 is sleeved on the outside of the guide rods 13. The outer ends of the pressure sensor 1 and the temperature sensor 2 are used to connect to the data acquisition system. The pressure sensor 1 is model FST800-215, and the temperature sensor 2 is model CWDZ11A.

[0020] The temperature sensor 2 is threadedly connected to the first screw groove 8, and the screw tube 7 is threadedly connected inside the detection tube 6. The probe of the temperature sensor 2 extends into the interior of the connecting seat 3 through the screw tube 7 and the detection tube 6 to detect the internal temperature.

[0021] The pressure plate 10 is located outside the outer end of the screw tube 7 and is rotatably arranged. Several locking blocks 11 and several locking slots 9 are arranged in a ring. The locking blocks 11 and the locking slots 9 are engaged. The pressure plate 10 slides outward through the first spring 14 to engage the locking blocks 11 and the locking slots 9, thus preventing the screw tube 7 from rotating loose.

[0022] The guide rod 13 is fixedly connected to the pressure plate 10. The guide rod 13 slides through the inside of the fixed plate 12. The guide rod 13 is used to position the pressure plate 10 and prevent the pressure plate 10 from rotating.

[0023] Specifically, the pressure plate 10 is slid inward to disengage the locking block 11 from the slot 9, and the rotating screw tube 7 is slid outward so that the detection end of the temperature sensor 2 probe is located in the middle of the connecting seat 3. The pressure plate 10 is driven by the first spring 14 to lock the locking block 11 into the slot 9. The pressure plate 10 is positioned by four guide rods 13 to prevent the screw tube 7 from rotating and loosening.

[0024] Example 2 See Figure 3 Furthermore, based on Embodiment 1, the top of the connecting seat 3 is provided with a second threaded groove 15, and the pressure sensor 1 is threadedly connected to the second threaded groove 15. The sealing mechanism 5 includes a fixing frame 16, which is fixedly installed inside the connecting seat 3. A slide rod 17 is movably installed through the connecting seat 3, and a second spring 18 is sleeved on the outside of the slide rod 17. A sealing disc 19 is fixedly installed at the top of the slide rod 17. Several first through holes 20 are opened through the inner and outer walls of the sealing disc 19, and several second through holes 21 are opened through the top of the sealing disc 19.

[0025] The top view of the fixed frame 16 is arranged in a "+" shape. The slide rod 17 passes through the inside of the fixed frame 16 and is slidably arranged. The slide rod 17 is positioned inside the connecting seat 3 by the fixed frame 16, and the sealing plate 19 is automatically pushed upward by the second spring 18.

[0026] The second spring 18 is located between the fixed frame 16 and the sealing plate 19. The top and bottom of the sealing plate 19 are interconnected through the first through hole 20 and the second through hole 21. The sealing plate 19 slides down and disengages from the bottom end of the second screw groove 15. The gas inside the connecting seat 3 enters the probe of the pressure sensor 1 through the first through hole 20 and the second through hole 21 to detect the pressure.

[0027] Specifically, the bottom end of the probe of pressure sensor 1 contacts the top of the sealing plate 19. The sealing plate 19 descends and disengages from the bottom end of the second screw groove 15. The gas inside the connecting seat 3 enters the probe of pressure sensor 1 through the first through hole 20 and the second through hole 21 for pressure detection. The probe of pressure sensor 1 disengages from the sealing plate 19. The sealing plate 19 slides upward to seal the first through hole 20, reducing the discharge of internal gas.

[0028] In actual operation, the bottom end of the connecting seat 3 is connected and fixed to the equipment to be tested, the pressure sensor 1 is connected to the second screw groove 15, the temperature sensor 2 is used to detect the pressure of the internal medium, the temperature sensor 2 is connected to the first screw groove 8, and the temperature sensor 2 is used to detect the temperature of the internal medium. During adjustment, the temperature sensor 2 is connected and fixed to the first screw groove 8, so that the probe of the temperature sensor 2 extends into the interior of the connecting seat 3 to detect the temperature. Before installation, the length of the probe of the temperature sensor 2 is observed in advance. When the length of the probe of the temperature sensor 2 is long, the pressure plate 10 is slid inward to make the locking block 11 disengage from the slot 9. The screw tube 7 is rotated and slid outward under the action of the thread so that the detection end of the probe of the temperature sensor 2 is located in the middle of the connecting seat 3. After the adjustment is completed, the pressure plate 10 is slid outward under the action of the first spring 14 so that the locking block 11 is locked into the slot 9. The pressure plate 10 is positioned by four guide rods 13 to prevent the screw tube 7 from rotating and loosening. When making a sealing connection, the pressure sensor 1 is fixed to the second screw groove 15. During connection, the bottom end of the probe of the pressure sensor 1 contacts the top of the sealing plate 19. The probe slides downward through the thread of the second screw groove 15, causing the sealing plate 19 to descend. At the same time, the second spring 18 contracts. When the sealing plate 19 disengages from the bottom end of the second screw groove 15, the gas inside the connecting seat 3 enters the probe of the pressure sensor 1 through the first through hole 20 and the second through hole 21 for pressure detection. When removed, the probe of the pressure sensor 1 disengages from the sealing plate 19, and the slide rod 17 drives the sealing plate 19 to slide upward through the second spring 18, sealing the first through hole 20 and thus reducing the internal gas discharge.

[0029] By setting the adjustment mechanism 4, the solenoid 7 slides inside the detection tube 6 via the thread, which facilitates the adjustment of the detection position of the probe of the temperature sensor 2. It is suitable for probes of different lengths. The pressure plate 10 slides outward via the first spring 14, so that the locking block 11 engages with the locking groove 9, preventing the solenoid 7 from automatically rotating and loosening, thus improving stability. By setting the sealing mechanism 5, the probe of the pressure sensor 1 contacts the top of the sealing plate 19, causing the sealing plate 19 to slide downward. Through the first through hole 20 and the second through hole 21, the second screw groove 15 can be automatically opened, allowing the detection medium to enter the probe of the pressure sensor 1 for detection. The sealing plate 19 slides upward via the second spring 18, which can automatically seal the pressure sensor 1 after disassembly, reducing the discharge of internal medium.

The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field.
