The present invention will be described in detail below with reference to the accompanying drawings and embodiments creates.
A kind of irrigation Special electromagnetic flowmeter, as shown in Figure 1 to Figure 3, including what is be arranged in measurement pipe 1 and measurement pipe 1
Sensor module；The measurement pipe 1 is equipped with the installing pipe 2 for sensor module to be arranged；The sensor module includes bottom
The sensor main body 3 being arranged on pipe 6 and bottom tube 6；Installing pipe 2 is inserted into 6 bottom of bottom tube, is equipped at the top of bottom tube 6 for solid
Determine the locknut 4 of bottom tube；The installing pipe 2 is equipped with the screw thread for installing locknut 4；The sensor main body 3 is equipped with and is used for
It is bonded the annular partition 7 of bottom tube inner wall, partition 7 is welded on sensor main body, and partition is equipped with seal assembly.
Since the pipeline for being generally used for irrigating is thinner, and need temporarily to assemble electromagnetic flowmeter when in use, because
This common large-scale electromagnetic flowmeter generally can not be applicable in, and this irrigation Special electromagnetic flowmeter can described in the invention
To be pre-assembled on pipeline, measurement pipe 1 can be made to use as normal pipeline by blocking installing pipe 2, be flowed
When measurement, sensor module need to be only installed in installing pipe, it is easy to operate, Electromagnetic Flow may be implemented
The quick assembling of meter.
4 bottom of locknut is fixed in bottom tube 6, and top is equipped with the through-hole for installing sensor main body 3；The locknut
Rubber seal also can be set in the position of upper corresponding through-hole, and the rubber seal of such through hole can guarantee locknut and sensing
The leakproofness of device ontology junction；The sensor main body top passes through through-hole and is equipped with flow converter 5, sensor main body bottom
End protrudes into measurement pipe and is equipped with the test electrode 8 connecting with flow converter.After bottom tube is inserted into installing pipe, by rotating locknut
It is threadedly coupled locknut with installing pipe, sensor module can be thus installed in installing pipe, be assembled up
Very convenient, the test electrode 8 of sensor bottom end gos deep into measurement pipe measuring at this time, and by data transfer to flow
Converter is shown that flow sensor 5 and test electrode 8 are the prior art, is not being repeated herein.
The locknut 4 is equipped with the fitting groove 9 for connecting with installing pipe 2, is connect by fitting groove 9 with installing pipe, can
So that locknut entangles installing pipe, guarantee the leakproofness at locknut edge；Being connect in this way by fitting groove 9 with installing pipe not only ensure that
The leakproofness at locknut edge, and the close of locknut and sensor main body junction is realized by the seal with elastometic washer of through hole
Envelope, thus substantially increases the leakproofness of locknut entirety；
Several sealing rings 13 are equipped on the outside of the bottom tube 6, bottom tube is equipped with the groove 10 for installing sealing ring 13, due to
Bottom tube is sleeved in installing pipe, by the way that several sealing rings 13 are arranged in bottom tube, so that locknut is after installing, bottom tube
First play certain sealing function, since bottom tube is bonded with installation inside pipe wall, by the sealing of several sealing rings so that liquid without

Ring 12；The sealing rubber ring 11 is mounted on partition towards on the side of locknut in concentric circles.It can be incited somebody to action by setting partition
Water gear, different from the side for being equipped with sealing rubber ring, thus significantly reduces the sealed pressure of through hole, passes through simultaneously in partition
Guide ring 12 is set, good impermeable role can be played in guarantee partition, since guide ring itself has support and guiding
Effect also allows partition movement appropriate in bottom tube by the way that guide ring is arranged, to enable sensor body according to reality
Border situation is appropriate to adjust the length for protruding into measurement pipe, so that sensor body be made preferably to work；Guide ring can be using existing
There are the guide ring of the PTFE used on piston rod or piston or polyformaldehyde material,
In actual use, to obtain more preferable leakproofness, partition 7 can be adjacent to locknut setting, be in same on such partition 7
Several sealing rubber rings 11 of heart circle setting can be bonded with locknut, to play multi-stage sealed effect, be substantially increased
The leakproofness of locknut has very big pressure in pipe, after water enters bottom tube, water will be withstood since measurement pipe is when crossing water
Partition withstands on partition on locknut, can thus partition be made further to be adjacent to locknut, so that sealing rubber ring be made preferably to rise
To sealing function.
The invention structure is simple, easy to use, is very suitable for the flow measurement of irrigation pipeline, and this irrigation is dedicated
Electromagnetic flowmeter can be pre-assembled on pipeline, measurement pipe can be made to use as normal pipeline by blocking installing pipe,
When needing to carry out flow measurement, sensor module need to be only installed in installing pipe, easy to operate, Ke Yishi
The quick assembling of existing electromagnetic flowmeter；The sealing that not only ensure that locknut edge is connect with installing pipe by the fitting groove on locknut
Property, and the sealing of locknut Yu sensor main body junction is realized by the seal with elastometic washer of through hole, thus mention significantly
The high leakproofness of locknut entirety.
The invention can be kept off water in the lower section of partition, thus greatly by the way that partition is arranged on sensor main body
The sealed pressure of through hole is alleviated greatly, while by setting guide ring, can play good impermeable role in guarantee partition
While, also move partition suitably in bottom tube, to enable sensor body adjusting appropriate according to the actual situation
The length for protruding into measurement pipe, makes sensor body preferably work, and by the way that seal assembly is arranged on partition, so that partition
When being adjacent to locknut, can further through-hole be blocked and be sealed, further improve the leakproofness of locknut, so as to
To guarantee the normal work of sensor module, flow detection precision is improved.
