Problems solved by technology

[0003] When the sensor of the currently used ultrasonic flowmeter is damaged, it is necessary to cut off the gas transmission work of the pipeline where the flowmeter is located, then empty the gas in the pipeline and replace it before replacing the sensor, or disassemble the entire flowmeter After that, it is repaired and replaced. This operation method makes the process of replacing or maintaining the sensor of the ultrasonic flowmeter complicated and cumbersome, which greatly slows down the work efficiency.

Embodiment 1

[0040] Example 1, such as Figure 1-6 As shown, a sensor 2 online replacement device suitable for high pressure conditions, on the original transportation pipeline, is provided with a base 1 connected to the transportation pipeline, a sensor 2 that penetrates into the transportation pipeline from the inside of the base 1, and a sensor 2 connected to the base 1 screw and clamp the sensor 2 on the hollow inner hexagon 22 on the base 1, the rear end of the sensor 2 is provided with an external thread 21, and the base 1 is provided with a fastening threaded hole 11.

[0041] The device in this embodiment includes a manual ball valve 3 and a pipe sleeve assembly. One side of the manual ball valve 3 is detachably connected to the base 1 through a fixed seat 31, and the other side is connected to the pipe sleeve assembly. When the manual ball valve 3 is open, the manual ball valve 3 A through opening is formed inside, and the through opening forms an air chamber with the inner cavity...

Embodiment 2

[0054] Example 2, such as Figure 8 As shown, an online replacement method for sensor 2 applicable under high pressure conditions, the method described in this embodiment relies on the device in Embodiment 1, and will not be repeated here. This embodiment includes the following steps:

[0055] S1: Assemble the manual ball valve 3: install the manual ball valve 3 on the base 1 through the fixing seat 31, first fix the fixing seat 31 and the base 1 through the second fastening threaded hole 32 and the fastening threaded hole 11 with bolts and Tighten, and then screw the manual ball valve 3 on the fixed seat 31;

[0056] S2: Combined sleeve assembly: push one end of the No. 1 inner sleeve 5 stretching thread 51 from the front end of the outer sleeve 4 into the outer sleeve 4, and push one end of the stretching thread 51 from the rear end with the limit pad 55 Push out to ensure that the No. 1 inner sleeve 5 will not rotate in the outer sleeve 4; push one end of the square rotati...

Abstract

The present invention provides a device and method for on-line replacement of sensors suitable for high-pressure conditions. Through the manual ball valve and the sleeve assembly installed on the outside of the sensor and the base, the assembly of the manual ball valve, the combined sleeve assembly, the assembly of the sleeve assembly, Check before disassembly and inject nitrogen, connect the sensor with the sleeve assembly, disassemble the sensor, check after disassembly, replace the sensor, check after installation, and restore the sensor. Build a sealed space outside the sensor, and pass through the No. 1 inner sleeve and the No. 2 inner sleeve. The inner sleeve and the inner core rod are coordinated with each other, the sensor and the hollow inner hexagon are disassembled and installed, and the sensor is replaced online under pressure. The gas transmission process does not need to be interrupted, and the gas in the transportation pipeline does not need to be vented or replaced. high working efficiency.

Description

technical field [0001] The invention relates to the field of gas flow meter devices, in particular to an online sensor replacement device and method suitable for high pressure conditions. Background technique [0002] The sensor of the ultrasonic flowmeter is generally inserted into the base fixed on the transportation pipeline, and then the hollow inner hexagon is screwed on the base to clamp the sensor. The sensor itself is provided with a sealing ring. Good airtightness. [0003] When the sensor of the currently used ultrasonic flowmeter is damaged, it is necessary to cut off the gas transmission work of the pipeline where the flowmeter is located, then empty the gas in the pipeline and replace it before replacing the sensor, or disassemble the entire flowmeter After it is down, it is repaired and replaced. This operation method makes the process of replacing or maintaining the sensor of the ultrasonic flowmeter complicated and cumbersome, which greatly slows down the wo...
