Differential pressure transmitters are widely used in industries such as industry, chemical industry, petroleum, and electric power, and have important application value and functions.

[0003] For example, the application with publication number CN207622919U discloses a pressure transmitter for pipeline detection, wherein a pressure lead pipe is arranged at the bottom of the pressure transmitter body, a display screen and a control button are installed on one side of the pressure transmitter body, an alarm is installed on the top of the pressure transmitter body, a microprocessor, a pressure sensor and a temperature sensor are installed inside the pressure transmitter body, an isolation diaphragm is arranged inside the pressure sensor, the temperature sensor is connected to the microprocessor through a temperature compensation circuit, and the microprocessor is electrically connected to the display screen, the control button, the alarm, the pressure sensor and the differential pressure sensor respectively. A temperature sensor and is arranged to detect the external temperature, eliminate the influence of temperature on pressure detection, and increase the detection accuracy.

[0004] However, the pressure transmitter in the application cannot provide position limit protection for the pressure gauge of the pressure transmitter. When the pressure gauge is outdoors or the detection pipeline vibrates greatly, the pressure gauge housing is easily damaged, thereby affecting the service life of the pressure gauge. A pressure transmitter for pipeline detection that can protect the pressure gauge is now provided. Utility Model Content

[0016] In a preferred embodiment, a curved hook is movably inserted into the surface of the supporting telescopic rod.

[0017] By adopting the above technical solution, after the transmitter connecting thread is screwed into the measuring pipe, the bent hook is adjusted up and down until the measuring pipe is placed in the concave part of the bent hook, thereby lifting the measuring pipe, maintaining the stability of the overall device, and ensuring the stable placement of the measuring pipe, which is convenient for the detection of pressure values.

When the pressure gauge of the commonly used pressure transmitter is outdoors or the vibration of the detection pipeline is large, the pressure gauge 3 is easy to collide with other objects. The pressure gauge shell is easy to be damaged, which in turn affects the service life of the pressure gauge 3. After the user completes the installation of the overall device, the limit telescopic rod 8 is extended forward to a suitable position to ensure that the anti-collision foam 10 can be close to the pressure gauge 3, which plays a protective role on the pressure gauge 3, and the pressure gauge 3 will not be damaged by collision with other objects outdoors.

[0031] The lower surface of the pressure gauge support plate 1 is fixedly mounted with a transmitter weighing frame 5, and the upper surface of the base of the transmitter weighing frame 5 is movably mounted with a pressure transmitter body 7. The lower surface of the pressure transmitter body 7 is fixedly mounted with a threaded hole, and the hole is movably plugged with a transmitter connecting thread 6. The pressure transmitter is installed as a whole. The pressure transmitter body 7 is placed on the transmitter weighing frame 5 to protect the pressure transmitter body 7. The transmitter connecting thread 6 can be connected to the measuring pipe 12 to detect the detected pipe. The threaded hole tightly connects the pressure gauge 3, the pressure transmitter body 7 and the transmitter connecting thread 6 together, and it is easy to disassemble and assemble.

[0032] Holes are provided on both sides of the transmitter weighing frame 5, and limit bolts 11 are movably inserted in the holes, and a circular ring fastening sleeve 4 is fixedly installed on one side of the limit bolt 11. During the operation of the pressure transmitter, the user can tighten the limit bolt 11 inward to a suitable position, and the curvature of the circular ring fastening sleeve 4 is the same as that of the pressure transmitter body 7. After the limit bolt 11 is tightened, the circular ring fastening sleeve 4 will fit with the pressure transmitter body 7, ensuring that the device will not move or tilt during operation, affecting the detection data.

[0033] The surface of the transmitter connecting thread 6 is movably plugged with a measuring pipe 12. 6 can be connected to the measuring pipe 12 to detect the detected pipe. The diameter of the transmitter connecting thread 6 is large, and the operation is simple and the installation is convenient.

[0034] A support plate limiting ring 13 is welded at the edge of the base of the pressure gauge support plate 1, and a supporting telescopic rod 14 is fixedly inserted on the inner wall surface of the support plate limiting ring 13.

[0037] The implementation principle of the pressure transmitter embodiment for pipeline detection in the present application is as follows:

[0038] When the pressure gauge of the commonly used pressure transmitter is outdoors or the detection pipeline vibrates greatly, the pressure gauge 3 is easy to collide with other objects. The pressure gauge shell is easy to be damaged, which in turn affects the service life of the pressure gauge 3. After the user completes the installation of the entire device, the limit telescopic rod 8 is extended forward to a suitable position to ensure that the anti-collision foam 10 can be close to the pressure gauge 3, which plays a protective role on the pressure gauge 3 and will not be damaged by collisions with other objects outdoors. After the transmitter connecting thread 6 is screwed into the measuring pipeline 12, the curved hook 15 is adjusted up and down until the measuring pipeline 12 is placed in the concave part of the curved hook 15, which can lift the measuring pipeline 12, maintain the stability of the entire device, and ensure the stable placement of the measuring pipeline 12, which is convenient for the detection of pressure values.

[0039] During the operation of the pressure transmitter, the user can tighten the limit bolt 11 inward to a suitable position.

After the overall device is installed, adjust the length of the supporting telescopic rod 14 and place the load-bearing base plate 16 on the ground, which improves the stability and safety of the overall device and the accuracy of data detection.
