Technical Field
[0001] This utility model relates to the field of installation and disassembly technology of pressure transmitters for argon pipeline testing, specifically to a pressure transmitter for argon pipeline testing that is easy to install. Background Technology
[0002] Argon is a colorless and odorless monatomic gas. Its density is 1.4 times that of air and 10 times that of helium. As an inert gas, argon does not react chemically with other substances at room temperature and is insoluble in liquid metals at high temperatures, making it particularly advantageous for welding non-ferrous metals.
[0003] A pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. It can convert the physical pressure parameters of gas, liquid, etc. sensed by the pressure measuring element sensor into standard electrical signals (such as 4~20mA DC), which are then supplied to secondary instruments such as indicators, alarms, recorders, and controllers for measurement, indication, and process regulation.
[0004] Most pressure transmitters currently on the market use flange connections and bolt fastening, which makes it difficult to install quickly and disassemble them quickly after installation. Loose installation can lead to insufficient measurement accuracy, reduce installation efficiency, and result in poor flexibility and inconvenience. Therefore, this paper proposes an easy-to-install pressure transmitter for argon pipeline inspection to solve the above problems. Utility Model Content

[0030] The present invention will be further described in detail below with reference to embodiments:
[0031] Example 1: As Figure 1-5 As shown, this utility model provides a pressure transmitter for easy installation of argon pipeline testing, including a pressure transmitter body 1. A sealing unit 2 is provided on the bottom side of the pressure transmitter body 1, a fastening unit 3 is provided on the inner side of the sealing unit 2, an installation unit 4 is provided on the inner side of the fastening unit 3, and an anti-slip unit 5 is provided on the bottom side of the installation unit 4. The installation unit 4 includes a semi-threaded rod 41, which is located on the inner side of the fastening unit 3. A second buckle 42 is provided on the inner side of the semi-threaded rod 41, and a gear 43 is fixedly connected to the inner side of one end of the semi-threaded rod 41. A rack 44 is meshed on one side of 43. A groove 45 is provided on the inner side of the rack 44. The inner side of the groove 45 is slidably connected to the inside of the fastening unit 3. By placing the groove 45 on the inner side of the mounting plate 31, the rack 44 and the gear 43 mesh with each other. At the same time, rotating the semi-threaded rod 41 drives the rack 44 on one side of the gear 43 to move on the inner side of the mounting plate 31. This causes the anti-slip block 55 to contact the bottom surface of the argon pipeline 24, thereby locking the buckle 42 onto the semi-threaded rod 41 and completing the fixation of the pressure transmitter body 1.
[0032] Example 2: As Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the sealing unit 2 includes a connecting pipe 21, which is fixedly connected to the bottom surface of the pressure transmitter body 1. One end of the connecting pipe 21 is fixedly connected to a positioning block 22, and the bottom surface of the positioning block 22 is fixedly connected to a sealing block 23. An argon gas pipeline 24 is provided on the bottom side of the sealing block 23. An inner groove 25 is opened on the inner side of the argon gas pipeline 24, and the inner side of the inner groove 25 is sleeved with the inner side of the argon gas pipeline 24. The fastening unit 3 includes a mounting plate 31, which is fixedly connected to the outside of the positioning block 22. A threaded rod 32 is threadedly connected to the inner side of the mounting plate 31, and a buckle 33 is provided on the inner side of the threaded rod 32. One end of the threaded rod 32 is rotatably connected to a moving plate 34. A T-shaped rod 35 is installed through the inner side of the moving plate 34, and a spring 36 is sleeved on the outer side of the T-shaped rod 35. One end of the spring 36 is fixedly connected to a positioning anti-tilt block 37. During the movement of the rack 44, the positioning block 22 on the bottom side of the connecting pipe 21 is driven to engage with the inner groove 25 inside the argon pipeline 24, thus completing the installation between the pressure transmitter body 1 and the argon pipeline 24. At the same time, the threaded rod 32 is controlled to drive the moving plate 34 to move downward, and the positioning anti-tilt block 37 is driven to contact the top surface of the inner side of the argon pipeline 24. This causes the spring 36 to be compressed, and through the elastic force, the positioning anti-tilt block 37 is pressed tightly against the inner side of the argon pipeline 24, further improving the seal between the pressure transmitter body 1 and the argon pipeline 24.
[0033] Example 3: As Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the anti-slip unit 5 includes a positioning groove 51, which is disposed on the bottom side of the semi-threaded rod 41. A fixing groove 52 is fixedly connected to the inner side of the positioning groove 51. An installation groove 53 is opened on the inner side of the positioning groove 51. A threaded hole 54 is opened on the inner side of the installation groove 53. An anti-slip block 55 is slidably connected to the inner side of the installation groove 53. A fixing bolt 56 is rotatably connected to the inner side of the anti-slip block 55. The inner side of the fixing bolt 56 is rotatably connected to the inside of the threaded hole 54. During installation and disassembly, the anti-slip block 55 can protect the inner side of the argon pipeline 24. At the same time, after long-term use, it can be removed from the inner side of the threaded hole 54 by fixing bolt 56, and the worn anti-slip block 55 can be disassembled and replaced, thereby improving the service life of the device.
[0034] The working principle of this easy-to-install pressure transmitter for argon pipeline inspection will be explained in detail below.
[0035] like Figure 1-5As shown, by placing the slide groove 45 inside the mounting plate 31, the rack 44 and gear 43 mesh with each other. Simultaneously, rotating the semi-threaded rod 41 moves the rack 44 on one side of the gear 43 inside the mounting plate 31, causing the anti-slip block 55 to contact the bottom surface of the argon pipeline 24. This engages the latch 42, securing the semi-threaded rod 41 to prevent loosening. Simultaneously, as the rack 44 moves, the positioning block 22 on the bottom side of the connecting pipe 21 engages with the inner groove 25 inside the argon pipeline 24, completing the installation between the pressure transmitter body 1 and the argon pipeline 24. Then, the threaded rod 32 is controlled again to move the moving plate 34 downwards. Simultaneously, the positioning anti-tilt block 37 contacts the top surface of the inner side of the argon pipeline 24, thereby compressing the spring 36. Through the elastic force, the positioning anti-tilt block 37 is pressed tightly against the inner side of the argon pipeline 24, further improving the seal between the pressure transmitter body 1 and the argon pipeline 24. Then, the control buckle 33 clamps the threaded rod 32, thus completing the installation and fixing of the pressure transmitter body 1. During installation and disassembly, the anti-slip block 55 can protect the inner side of the argon pipeline 24. After long-term use, the anti-slip block 55 can be removed from the inside of the threaded hole 54 by the fixing bolt 56, and then the worn anti-slip block 55 can be disassembled and replaced, thereby extending the service life of the device.
[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
