Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pressure transmitters, in particular to a buffer docking type pressure transmitter. Background Art
[0002] The pressure transmitter can convert the physical pressure parameters of gas, liquid, etc. sensed by the pressure measuring element sensor into a standard electrical signal (such as 4~20mADC, etc.) to provide secondary instruments such as indicator alarms, recorders, and regulators for measurement, indication, and process adjustment.
[0003] The patent, with publication number "CN221685757U," is titled "Specialized Oxygen Pressure Transmitter." The device described in this publication features staggered, inclined baffles within a spiral tube to decelerate the gas. However, this design suffers from the following drawbacks: while the baffles can block the gas flow, the blocked gas and the subsequent gas discharged into the spiral tube create convection currents. Over time, this convection current can easily damage the baffles, compromising their gas-blocking effectiveness. This utility model addresses this issue by designing a buffered docking pressure transmitter. Utility Model Content
[0004] The purpose of the utility model is to provide a buffer docking type pressure transmitter to solve the problems raised by the above background technology.

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example 1
[0028] like Figure 1 、 Figure 2 、 Figure 4As shown, the device includes a pressure transmitter body 1, a connector 2 and a partition 3. The connector 2 is fixed through the bottom of the pressure transmitter body 1, the partition 3 is fixed at the middle end of the connector 2, and a buffer assembly 4 is provided inside the connector 2. The buffer assembly 4 includes a U-shaped rod 401 that slides through the bottom of the partition 3, and a slider 402 made of rubber fixed on the top of the U-shaped rod 401 is slidingly connected to the connector 2. A mounting block 403 made of rubber is fixed at the upper end of the connector 2, and an L-shaped hole 404 is integrally provided inside the mounting block 403. A U-shaped hole 405 is integrally provided on the left side of the connector 2, and exhaust holes 406 are integrally provided on the left and right sides of the partition 3. A first spring 407 is fixed on the front and back sides of the top of the partition 3, and the end of the first spring 407 away from the partition 3 is fixedly connected to the bottom of the slider 402.
[0029] A circular guide groove 5 is integrally provided at the lower end of the interior of the connector 2. The center of the guide groove 5 is concentric with the center of the connector 2. The U-shaped rod 401, the exhaust hole 406 and the first spring 407 are staggered. The exhaust hole 406, the U-shaped hole 405 and the L-shaped hole 404 are through-hole designs. Connecting blocks 6 are slidably connected on the left and right sides of the guide groove 5. A connecting sleeve 7 is fixedly sleeved on the outside of the connecting block 6, and the center of the connecting sleeve 7 is concentric with the center of the connector 2. A threaded sleeve 8 is fixed at the lower end of the interior of the connecting sleeve 7. A sealing ring 9 provided at the bottom of the threaded sleeve 8 is fixedly connected to the connecting sleeve 7.
[0030] The staff first rotates the connecting sleeve 7 so that the connecting sleeve 7 drives the threaded sleeve 8 together with the connecting block 6 to rotate along the center direction of the guide groove 5, and then connects the threaded sleeve 8 to the external pipe through a threaded connection, and the sealing ring 9 seals the state after the connector 2 is connected to the external pipe. When the gas is discharged from the external pipe into the interior of the connector 2, the gas passes through the exhaust hole 406 to push the slider 402 to drive the U-shaped rod 401 to move along the direction of the mounting block 403, thereby misaligning the slider 402 with the lower end of the U-shaped hole 405, and the first spring 407 is deformed. In the above manner, the instantaneous impact force of the gas discharged into the interior of the connector 2 is buffered. At this time, the gas is discharged from the U-shaped hole 405 through the L-shaped hole 404 into the interior of the pressure transmitter body 1.
[0031] Example 2
[0032] like Figure 2 、 Figure 3 、 Figure 5As shown, a connecting pin 10 is fixedly provided at the middle end of the U-shaped rod 401, and the connecting pin 10 and the first spring 407 are in an offset design. The connecting pin 10 passes through the partition 3 and the slider 402, and a mounting hole 11 is integrally provided inside the connecting pin 10. The mounting hole 11 is designed to be L-shaped and is a through hole. A cavity 12 is integrally provided at the lower end of the mounting block 403, and a slide plate 13 is slidably connected inside the cavity 12. A clearance hole 14 is integrally provided at the lower right end of the mounting block 403, and the slide plate 13 is made of rubber. Second springs 15 are fixedly provided on the left and right sides of the top of the slide plate 13, and the end of the second spring 15 away from the slide plate 13 is fixedly connected to the mounting block 403. A connecting hole 16 is integrally provided at the upper right end of the connector 2, and limit blocks 17 are fixedly provided on the left and right sides of the lower end of the connector 2.
[0033] According to the operating method in Example 1, when the gas is discharged into the interior of the connector 2, the gas passes through the exhaust hole 406 and the mounting hole 11 in a diversion manner in sequence. The gas passing through the mounting hole 11 is discharged into the position between the mounting block 403 and the slider 402. At this time, the gas in this area pushes the slide 13 to move upward along the direction of the cavity 12, and the second spring 15 is deformed, so that the gas between the mounting block 403 and the slider 402 is discharged from the give way hole 14 through the connecting hole 16 into the interior of the pressure transmitter body 1. By means of gas diversion, the impact force of the gas discharged into the interior of the connector 2 is reduced, that is, the buffering effect of the gas discharged into the interior of the pressure transmitter body 1 is further improved. After using the device, the staff separates the external pipe from the connector 2, and the slide plate 13 is reset by the rebound force of the second spring 15, that is, the slide plate 13 blocks the hole 14. At the same time, the rebound force of the first spring 407 drives the slider 402 to reset the U-shaped rod 401 and the connecting pin 10, and then the slider 402 blocks the U-shaped hole 405, and the limit block 17 limits the reset position of the U-shaped rod 401.
[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
