[0033] The working principle of the new wedge-shaped flowmeter provided by the utility model is as follows:

[0034] The first step: when in use, the two fixing rings 5 ​​are both stuck on the straight tube 1 and located on both sides of the wedge block 4, and the two fixing rings 5 ​​are in contact with the wedge block 4 to limit and fix the wedge block 4. At the same time, the two sets of limit card blocks 11 are also stuck on the wedge block 4, and the two limit mounting plates 7 are respectively in contact with the two sides of the wedge block 4. Then, the two fixing rings 26 are also stuck on the straight tube 1 and in contact with the two fixing rings 5.

[0036] The third step: when disassembling, it is only necessary to pull out the limiting plug block 2 134, take out the elastic column 135, and then pull the limiting ring 133 to make the limiting plug cylinder 131 separate from the fixing ring 2 6, and then pull the fixing ring 2 6 to make the fixing ring 2 6 separate from the fixing ring 1 5, and then lift the fixing ring 1 5 to make the fixing ring 1 5, the limiting mounting plate 7 and the limiting block 11 separate from the wedge block 4, and then the wedge block 4 can be taken out to complete the disassembly work, so that the structure is simple, and it is convenient to disassemble and fix the wedge block 4, thereby improving the work efficiency.
