Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, and it is not used in restriction the utility model.
As Fig. 1 and Fig. 2 jointly shown in, a kind of valve opening detection device is installed on arc-shaped on 1 outer surface of pipeline
Slide rheostat 4 is equipped with butterfly valve on pipeline 1, and the cunning needle 5 of slide rheostat 4 is fixed on the valve rod 3 of butterfly valve, sliding needle 5 and mould
Number converter electrical connection, analog-digital converter and monolithic mechatronics, single-chip microcontroller are electrically connected with display, and the one of slide rheostat 4
A fixed pin and 5V power electric connection, another of slide rheostat 4 fix pin ground connection, and the resistance of slide rheostat 4 is complete
In full access circuit, i.e., the voltage at 4 both ends of slide rheostat is supply voltage 5V.
Wherein, as shown in Fig. 2, ACC be 5V power supply, GND indicate ground terminal, R indicate slide rheostat 4, analog-digital converter,
Single-chip microcontroller, display, 5V power supply and ground terminal are electrically connected on circuit board 6.
When rotating butterfly valve, valve rod 3 drives sliding needle 5 to rotate, then slides the voltage value at needle 5 and change, analog-digital converter inspection
It measures voltage signal and voltage signal is converted into digital signal, then digital signal is fed back into single-chip microcontroller, single-chip microcontroller handles number
Display is fed back to after word signal, display shows that opening for butterfly valve can be obtained in voltage value U, U at sliding needle 5 compared with 5V
Degree.
As shown in Fig. 2, the voltage value U at sliding needle 5 is zero when sliding needle 5 is fully located at the left end of slide rheostat 4, this
When, butterfly valve completely closes；When sliding needle 5 is fully located at the right end of slide rheostat 4, voltage value U is 5V, at this point, butterfly valve is complete
It opens.When sliding needle 5 is in a certain middle position, the voltage value U as display is shown is 3V, obtains butterfly valve compared with 5V voltage
Aperture be 60%.
The valve opening detection device of the utility model can also be used to detect opening for the changeover valves such as ball valve and plunger valve
Degree.
The above is the citing of the utility model preferred forms, wherein the part that do not address in detail is this field
The common knowledge of those of ordinary skill.The protection scope of the utility model is based on the contents of the claims, any to be based on this reality
The equivalent transformation carried out with novel technical inspiration, is also within the protection scope of the utility model.
