The first embodiment is as follows: referring to fig. 1 to 8, a valve opening monitoring device is provided, in which the valve is disposed between pipelines, such as a valve disposed on a natural gas pipeline. The valve comprises a valve body having a passage and a valve stem 1 disposed within the valve body. The valve rod 1 rotates relative to the valve body to adjust the opening and closing size of the valve, so that the flow in the channel is adjusted. The valve opening monitoring device includes:

the monitor 4 is fixed on the valve body through a bracket 3, the monitor 4 comprises a shell 41, a through hole 42 is formed in the shell 41, and a plurality of Hall elements 43 are arranged around the through hole 42;

the monitoring device comprises a shaft sleeve 5, a first part 51 and a second part 52 are arranged along the extension direction of the shaft sleeve 5, the first part 51 is sleeved on the valve rod 1, the second part 52 penetrates through the through hole 42 to one side, away from the valve, of the monitoring device 4, and the second part 52 is used for being sleeved with a hand wheel with a preset size; a magnet 6 is arranged on the shaft sleeve 5;

when the opening of the valve is adjusted, the hand wheel drives the shaft sleeve 5 to drive the valve rod 1 to rotate, and the magnet 6 can be opposite to the Hall element 43 under the rotation drive of the shaft sleeve 5, so that the state of the valve is obtained.

Cooperate with magnet 6 on a plurality of hall element 43 and the axle sleeve 5 in through the monitor 4, when magnet 6 was relative with hall element 43, hall element 43 both sides produced hall voltage, make hall element 43 send pulse signal and transmit for the controller, acquire axle sleeve 5 together with the number of revolutions of valve rod 1 from this, and calculate the valve aperture by the number of revolutions of valve rod 1, realize the real-time supervision to the valve state, the record, improve the accuracy of monitoring data, reduce staff's work load, guarantee the security of pipeline use. Specifically, as can be seen from testing, for a certain type of valve, the valve can be fully opened when the valve stem 1 is rotated 30 revolutions. Thus, during the actual monitoring process, the opening degree of the valve is converted according to the number of turns recorded each time the valve rod 1 rotates.

In order to satisfy the fixation of the monitoring instrument 4 on different kinds of valves. The bracket 3 can be of a split structure or an integrally formed structure. Referring to fig. 2, the bracket 3 of the split structure may include two supporting portions 31 and one fixing portion 32. The support portion 31 may be formed by bending a plate member a plurality of times. A burring for coupling with the fixing portion 32 is formed at one end of the supporting portion 31. A stopper connected to the cover plate 2 of the valve is formed at the other end of the support portion 31.

The fixing hole 512 is used for inserting a fixing member to fixedly connect the first portion 51 with the valve stem 1. Further guarantee the axle sleeve 5 can drive in step the valve rod 1 is rotatory. The second part 52 is used for sleeving a hand wheel with a preset size, and for valves of different types, opening and closing can be controlled by using the same hand wheel, so that the opening of the valve can be conveniently adjusted. A groove for fixing the magnet 6 is provided on the fixing platform 53. The hall element 43 is located on the side of the magnet 6 departing from the valve body, a groove is formed in the side of the fixed platform 53 departing from the valve body, the magnet 6 is arranged in the groove, and in a fixed state, the surface of the magnet 6 is flush with the surface of the fixed platform 53.

The casing 41 is internally provided with a PCB connected with the Hall element 43, the PCB is provided with a chip for data recording and calculation, a power supply 44 connected with the PCB, and a water immersion probe 45 connected with the PCB and penetrating through the casing 41 and extending towards the valve. The water logging probe 45 can be used for monitoring the water level of the valve body in the environment, and the use safety of the valve is guaranteed.

Example two: referring to fig. 9, a valve opening monitoring device is basically similar to the first embodiment in structure, and is different in that: when the hall element 43 is opposite to the magnet 6, the hall element 43 and the magnet 6 are arranged along the radial direction of the shaft sleeve 5 so as to meet different use requirements
