Cross magnetic absorption connection.
The connecting tube includes that the pipe jointing part point being connected with each other is connected with valve as a further improvement of the utility model,
Part, valve coupling part are connect with ball valve, and pipe jointing part point is removable to be connected to valve coupling part bottom end, pipe jointing part point
Bottom face is cambered surface.
The sensor module includes thermal flow rate sensor and water mist amendment as a further improvement of the utility model,
Sensor.
The utility model has the beneficial effects that：The utility model is provided with the dismantled and assembled depth tune for being looped around measuring rod periphery
Ring is saved, when needing to adjust the insertion depth of sensor module and measuring rod, can install or remove depth adjustment ring so that
Measuring rod upper and lower translation adjusts distance of the gauge outfit relative to ball valve, to adjust the insertion pipeline of sensor module and measuring rod
Depth, to realize that single flowmeter is applicable in the requirement of different tube diameters.
Description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the assembling schematic diagram of depth adjustment ring and measuring rod.
Specific implementation mode
Thermal mass flow meter as shown in Figure 1, including measuring rod 1, ball valve 2 and gauge outfit 3.Measuring rod 1 passes through ball valve 2,
The bottom end of measuring rod 1 is provided with sensor module, and gauge outfit 3 is arranged on 1 top of measuring rod, and 2 bottom end of ball valve is connected with connecting tube 4.
2 top of ball valve is also threaded with briquetting 8, and sealing ring 9 is pressed in 2 top of ball valve by briquetting 8, to realize 1 outer wall of measuring rod and pipe
Sealing between road, it is air tight.Connecting tube 4 is welded on pipeline 100 when use, ball valve 2 is screwed into 4 top of connecting tube, will survey
Gauge rod 1 is inserted into along the channel direction of ball valve 2 inside pipeline 100, and sensor module detects flow automatically.When needs safeguard the more change of current
Measuring rod 1 can be extracted out when gauge, close ball valve 2 later.
The mass flowmenter of embodiment further includes the depth adjustment ring 5 between gauge outfit 3 and ball valve 2, the depth adjustment
Ring 5 is removable to be looped around 1 periphery of measuring rod, and bottom can abut briquetting 8.Depth adjustment ring 5 to adjust measuring rod 1 into
Enter the depth inside pipeline, such as depth adjustment ring 5 can be removed when measuring the pipeline gas flow of Large Diameter Pipeline, then
Measuring rod 1 can move deeper to be inserted into duct orientation；And depth tune can be then packed into when measuring small-caliber pipeline gas flow
Ring 5 is saved, makes measuring rod 1 is opposite to translate up, the depth of pipeline is inserted into reduce measuring rod 1 and sensor module.So, lead to
Crossing the depth adjustment ring 5 of embodiment then realizes the requirement that single flowmeter is applicable in different tube diameters.
It is further preferred that depth adjustment ring 5 is there are two more than, more than two depth adjustment rings are set along short transverse
It sets, depth adjustment ring is more, then the range for the depth adjustment that measuring rod is inserted into is wider, and single flowmeter adapts to more multi-pipe-diameter
Measure pipeline.
It is further preferred that with reference to Fig. 2, the card slot 11 of twice or more is arranged along short transverse for the outer wall of measuring rod 1,
Depth adjustment ring 5 is embedded in card slot 11.The setting of card slot 11 facilitates the positioning of depth adjustment ring 5.
It is further preferred that and embodiment (not shown) in, depth adjustment ring 5 includes two semi-rings, two semi-rings
End set magnetic part, and connected by magnetic absorption between two semi-rings, facilitate the dismounting of depth adjustment ring 5.
It is further preferred that with reference to figure 1, above-mentioned connecting tube 4 includes that the pipe jointing part point 41 being connected with each other is connected with valve
Part 42, valve coupling part 42 are connect with ball valve 2, and pipe jointing part point 41 is removable to be connected to 42 bottom end of valve coupling part, pipe
The bottom face of coupling part 41 is cambered surface.User is in use, the cambered surface of pipe jointing part point 41 is bonded pipeline 100, and is welded on pipe
On road, and valve coupling part 42 facilitates the dismounting of flowmeter entirety with 41 removable structures of pipe jointing part point, meanwhile, user
41 can also divided using the preceding pipe jointing part by replacing different curvature radius cambered surface, so that flowmeter is easier and pipeline
Installation connection is also more convenient to connect with the Pipe installing of different tube diameters.
It is further preferred that sensor module, which includes thermal flow rate sensor 6 and water mist, corrects sensor 7, pass through setting
Two sensors can relatively accurately measure the flow of the gas-liquid two-phase mixed flow containing a large amount of water mists.Fluid flow detects
202582624 U of CN are can refer to the modified principle of water mist.
The above is the utility model preferred embodiment, is not constituted to scope of protection of the utility model
Limitation.
