Description

Technical Field

[0001] This utility model relates to the field of pressure transmitter technology, specifically a pressure transmitter that is easy to install and disassemble. Background Technology

[0002] A pressure transmitter is an industrial measuring instrument that uses a pressure sensor as its core sensing element to convert the pressure signal (absolute pressure, gauge pressure, differential pressure) of a fluid (liquid, gas, steam) into a standard electrical signal through physical sensing. This enables real-time acquisition, transmission, and remote monitoring of pressure parameters. Its core essence is to "convert non-electrical physical quantities (pressure) into quantifiable and transmissible electrical signals, replacing manual readings and close-range measurements to support precise control of industrial automation systems." Pressure transmitters are widely used in industrial automation, petrochemicals, water supply and drainage engineering, hydraulic and pneumatic systems, intelligent manufacturing, and energy and power industries. When using pressure transmitters, it is necessary to use a type of pressure transmitter that is easy to install and disassemble.

[0003] The existing pressure transmitters require multiple sets of bolts to fix the flange connection during installation. Precise alignment and one-by-one alignment of the bolt holes are required during installation, and bolts must be removed one by one during disassembly. The process is quite cumbersome, which increases the workload of operators. Utility Model Content

[0004] The purpose of this invention is to provide a pressure transmitter that is easy to install and disassemble, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure transmitter that is easy to install and disassemble, comprising a pressure transmitter body.

[0006] Mounting assembly located at the bottom of the pressure transmitter body;

[0007] The mounting assembly includes a mounting mechanism located at the bottom of the pressure transmitter body;

[0008] An auxiliary mechanism is provided at the bottom of the pressure transmitter body, and the auxiliary mechanism is connected to the mounting mechanism.

[0009] Preferably, the mounting mechanism includes a connector, which is fixedly mounted on the bottom of the pressure transmitter body. A flange is fixedly mounted on the bottom of the connector. A positioning rod is slidably mounted on the inner wall of the flange with a positioning hole. An mounting plate is fixedly mounted on the bottom of the positioning rod. A threaded sleeve is mounted on the side wall of the connector. An adjusting block is slidably mounted on the side wall of the connector. A rectangular block is hinged to the side wall of the adjusting block. A snap-fit ​​ring is fixedly mounted on the side wall of the rectangular block. The side wall of the snap-fit ​​ring is slidably connected to the inner wall of the positioning rod with a limiting groove.

[0010] Preferably, the inner wall of the threaded sleeve is threadedly connected to the connector, and the top of the threaded sleeve is in contact with the bottom of the adjusting block.

[0011] Preferably, there are six snap rings, and all six snap rings are of the same shape and size.

[0012] Preferably, the diameter of the positioning rod is the same as the inner wall diameter of the positioning hole on the flange, and the side wall of the positioning rod is slidably connected to the inner wall of the positioning hole.

[0013] Preferably, the auxiliary mechanism includes a sealing gasket, on both sides of which are fixedly installed with fitting sealing rings. The top of the fitting sealing rings contacts the bottom of the flange, and the bottom of the sealing gasket contacts the top of the mounting plate.

[0014] Preferably, the side wall diameter of the fitting sealing ring is the same as the inner wall diameter of the flange, the side wall diameter of the fitting sealing ring is the same as the inner wall diameter of the mounting plate, and the side wall of the fitting sealing ring is slidably connected to the inner wall of the mounting plate.

[0015] This invention provides a pressure transmitter that is easy to install and disassemble. It has the following advantages:

[0016] (1) In this utility model, the positioning rod on the mounting plate will be inserted into the inner wall of the positioning hole on the flange. Then the operator can directly rotate the position of the threaded sleeve. The inner wall of the threaded sleeve is threadedly connected to the connector. Therefore, when the threaded sleeve rotates, it can drive its own position to rise, and further drive the adjusting block to slide on the side wall of the connector. Under the action of the rectangular block, the adjusting block drives the position of the snap ring to rise, causing the bottom of the snap ring to snap and slide onto the inner wall of the arc groove on the positioning rod, effectively limiting the position of the positioning rod, thereby quickly realizing the installation and disassembly of the pressure transmitter body.

[0017] (2) When the operator uses the device, when it is necessary to install the pressure transmitter body, the sealing gasket is first installed in the middle of the flange and the mounting plate. The sealing ring at the upper position is in contact with the inner wall of the flange, and the sealing ring at the lower position will contact the inner wall of the mounting plate, thereby improving the sealing performance after the mounting plate and the flange are connected.

[0024] Example 1: A preferred embodiment of the pressure transmitter provided by this utility model that is easy to install and disassemble is, for example... Figures 1 to 4 As shown: A pressure transmitter that is easy to install and disassemble includes a pressure transmitter body 1.

[0025] Mounting assembly 4 is located at the bottom of the pressure transmitter body 1;

[0026] Mounting assembly 4 includes a mounting mechanism 41 located at the bottom of the pressure transmitter body 1;

[0027] An auxiliary mechanism 42 is provided at the bottom of the pressure transmitter body 1, and the auxiliary mechanism 42 is connected to the mounting mechanism 41.

[0028] The mounting mechanism 41 includes a connector 412, which is fixedly installed at the bottom of the pressure transmitter body 1. A flange 417 is fixedly installed at the bottom of the connector 412. A positioning rod 416 is slidably installed on the inner wall of the flange 417 with a positioning hole. An mounting plate 418 is fixedly installed at the bottom of the positioning rod 416. A threaded sleeve 413 is installed on the side wall of the connector 412.

A snap ring 415 is fixedly installed on the side wall of the rectangular block 414. The side wall of the snap ring 415 is slidably connected to the inner wall of the positioning rod 416 with a limiting groove.

[0029] In this embodiment, the inner wall of the threaded sleeve 413 is threadedly connected to the connector 412, and the top of the threaded sleeve 413 is in contact with the bottom of the adjusting block 411.

[0030] Furthermore, there are six snap rings 415, and all six snap rings 415 are of the same shape and size.

[0032] In the specific implementation process, the positioning rod 416 on the mounting plate 418 will be inserted into the inner wall of the positioning hole on the flange 417. Then the operator can directly rotate the position of the threaded sleeve 413. The inner wall of the threaded sleeve 413 is threadedly connected to the connector 412. Therefore, when the threaded sleeve 413 rotates, it can drive its own position to rise, further driving the adjusting block 411 to slide on the side wall of the connector 412. Under the action of the rectangular block 414, the adjusting block 411 drives the position of the snap ring 415 to rise, causing the bottom of the snap ring 415 to snap and slide onto the inner wall of the arc groove on the positioning rod 416, effectively limiting the position of the positioning rod 416, thereby quickly realizing the installation and disassembly of the pressure transmitter body 1.

The top of the fitting sealing ring 421 is in contact with the bottom of the flange 417, and the bottom of the sealing gasket 422 is in contact with the top of the mounting plate 418.

[0034] In this embodiment, the side wall diameter of the fitting sealing ring 421 is the same as the inner wall diameter of the flange 417, and the side wall diameter of the fitting sealing ring 421 is the same as the inner wall diameter of the mounting plate 418. The side wall of the fitting sealing ring 421 is slidably connected to the inner wall of the mounting plate 418.

[0035] In the specific implementation process, when the operator needs to install the pressure transmitter body 1, the sealing gasket 422 is first installed in the middle of the flange 417 and the mounting plate 418. The upper sealing ring 421 is in contact with the inner wall of the flange 417, and the lower sealing ring 421 is in contact with the inner wall of the mounting plate 418, which improves the sealing performance after the mounting plate 418 and the flange 417 are connected.
