Description

Technical Field

[0001] The utility model relates to the technical field of pressure transmitters, in particular to a high-precision pressure transmitter. Background Art

[0002] A pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. Most pressure transmitters on the market are intelligent and highly accurate. They can not only be used to measure the viscosity of the medium, but also to detect the corrosion resistance of the product. They have a wide range of uses.

[0003] At present, most existing pressure transmitters are connected to pipes at specified positions through threads. After the connection is completed, the position of the pressure transmitter display is fixed. Due to the variety of pipeline directions and spatial layouts in different installation areas, it is easy for the display on the pressure transmitter to face the pipeline position, resulting in the operator being unable to conveniently observe the data on the pressure transmitter display, thereby causing inconvenience in the use of the pressure transmitter. To this end, we propose a high-precision pressure transmitter to solve the above problem. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 A high-precision pressure transmitter comprises a pressure transmitter body 1, a connecting sleeve 2 is provided at the bottom end of the pressure transmitter body 1, and a docking tube 3 is inserted inside the connecting sleeve 2, a display screen is provided on the pressure transmitter body 1, and there are many precision components inside it, so it has the characteristics of high precision, and the specific working principle of the pressure transmitter body 1 is the existing technology, which will not be described in detail here. A threaded tube 4 is connected to the bottom end of the docking tube 3, a limit rod 5 is inserted laterally inside the connecting sleeve 2, and the end of the limit rod 5 is connected to a connecting rod 6, and the outer wall of the docking tube 3 is evenly provided with symmetrical grooves 12 that are compatible with the limit rod 5. By opening multiple groups of symmetrical grooves 12, the installation direction of the pressure transmitter body 1 can be adjusted.

[0023] Further, refer to Figure 1 and Figure 4 It can be seen that the connecting rod 6 is provided with an arc structure, and anti-slip particles are evenly distributed on the outside of the connecting rod 6. The connecting rod 6 provided with an arc structure can facilitate the staff to pull the limit rod 5 horizontally to move. Combined with the anti-slip particles distributed on the outside of the connecting rod 6, it can effectively prevent the staff from slipping during the process of pulling the connecting rod 6.

[0024] Further, refer to Figure 3 It can be seen that the inner side of the connecting rod 6 is laterally connected to the linkage rod 7, and the inner wall of the connecting sleeve 2 is provided with a guide groove adapted to the linkage rod 7. During the lateral movement of the connecting rod 6, the linkage rod 7 is forced to slide along the inner wall of the guide groove, thereby realizing the guiding operation of the connecting rod 6.

[0025] Further, refer to Figure 2 and Figure 3 It can be seen that the inner wall of the guide groove is laterally connected with a connecting spring 8, and the other end of the connecting spring 8 is fixedly connected to the linkage rod 7. Through the elastic characteristics of the connecting spring 8 itself, the stability of the limit rod 5 can be guaranteed when it is stuck in the symmetrical groove 12 opened inside the docking tube 3.

[0026] Further, refer to Figure 3 It can be seen that the top end of the docking tube 3 is connected to the rotating ring 13 through a bearing. Since the rotating ring 13 is connected to the docking tube 3 through a bearing, when the connecting sleeve 2 rotates, the rotating ring 13 can be driven to rotate at the same time. The inner side of the connecting sleeve 2 is connected to the sealing ring 10. The top end of the rotating ring 13 is provided with a sealing groove that is compatible with the sealing ring 10. The combination of the sealing ring 10 and the sealing groove can effectively ensure the sealing groove when the device is in use, and when the connecting sleeve 2 rotates, it can effectively prevent the sealing ring 10 from rotating directly on the inner wall of the sealing groove to cause wear.

[0027] Further, refer to Figure 1 and Figure 2It can be seen that the top of the connecting sleeve 2 is symmetrically connected to the docking block 11, and the side of the docking block 11 is connected to the outer wall of the pressure transmitter body 1 through bolts 14. The two sets of docking blocks 11 arranged in an L-shaped structure and combined with the setting of bolts 14 can facilitate the staff to disassemble the pressure transmitter body 1 and the connecting sleeve 2 to achieve the reuse of intact parts.

[0028] Further, refer to Figure 2 and Figure 3 It can be seen that a guide ring 9 is connected to the outer side of the butt joint 3, and an annular groove compatible with the guide ring 9 is opened on the inner wall of the connecting sleeve 2. The guide ring 9 and the annular groove arranged by the T-shaped structure can limit the connecting sleeve 2 during the rotation process. While ensuring that the connecting sleeve 2 can rotate normally, it can effectively prevent the connecting sleeve 2 from shifting up and down, thereby further improving the sealing performance of the device during use.

[0029] Working principle: When using the utility model, the staff can first transport the device to the installation area, and then install the device on the designated pipeline by rotating the threaded tube 4. After the installation is completed, if the display screen position on the pressure transmitter body 1 is blocked by the pipeline, the staff can pull the two sets of connecting rods 6 to move horizontally, so that the two sets of limiting rods 5 are forced to move away from each other and withdrawn from the symmetrical grooves 12 opened inside the butt tube 3. Then the staff can rotate the pressure transmitter body 1, so that the connecting sleeve 2 can be rotated at the same time. When the pressure transmitter body is When the connecting sleeve 1 is rotated to the appropriate direction, the staff can stop pulling the two sets of connecting rods 6, so that the limiting rod 5 is stuck in the corresponding symmetrical groove 12 inside the connecting pipe 3 to realize the limiting operation of the connecting sleeve 2. At this time, it is convenient for the staff to check the numbers displayed on the display screen of the pressure transmitter body 1. In addition, during the rotation of the connecting sleeve 2, the rotating ring 13 is simultaneously forced to rotate at the top of the connecting pipe 3. In combination with the sealing ring 10 and the sealing groove provided inside the rotating ring 13, water seepage can be effectively prevented from occurring in the device. The above is the entire working principle of the present utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated on.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
