Detailed description of the invention
Fig. 1 is the structure chart of butterfly valve automatic detection device in the embodiment of the present invention.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As shown in Figure 1, the butterfly valve automatic detection device in the present embodiment, comprising:
Butterfly valve 1, is fixed on station；It can carry out the detection of multiple butterfly valves 1 simultaneously as needed, so then setting is corresponding
The station of quantity, while realizing the clamping stagnation detection of multiple butterfly valves 1, so that detection efficiency is higher；
Cylinder 2 matches with the quantity of butterfly valve 1, and each butterfly valve 1 is correspondingly connected with a cylinder 2, and cylinder 2 is fixed on butterfly valve 1
2 fixed plate of cylinder on, the valve rod of the piston rod of cylinder 2 and butterfly valve 1 is sequentially connected, and is provided on cylinder 2 for detecting cylinder 2
The magnetic switch 3 of movement；If there is the case where clamping stagnation during 1 self-test of butterfly valve, resistance can be generated to the movement of cylinder 2
Power increases the time that cylinder 2 acts, and the time between switching signal that corresponding magnetic switch 3 obtains is also longer；
Control unit 4 is electrically connected with magnetic switch 3, for obtaining the switching signal of magnetic switch 3 and calculating switching signal
Time cycle；The control unit 4 includes controller 41 and the memory 42 being electrically connected with controller 41, display 43, alarm
Device 44, controller 41 is electrically connected to obtain the switching signal of the transmission of magnetic switch 3 with magnetic switch 3, and is obtained according to switching signal
Take the time interval of 2 one, cylinder movements back and forth；Controller 41 in the present embodiment uses PLC controller 41, and display 43 is then
Can various data to be stored in display-memory 42, display 43 can also show the status information in 1 test process of butterfly valve；
Alarm 44 can be using voice guard 44, alarm lamp etc., for prompting the unqualified information of butterfly valve 1；
Air supply channel 5 is connected between cylinder 2 and gas source, and air pressure regulator 6 is provided on air supply channel 5, and the gas supply is logical
Road 5 can provide power gas source for cylinder 2, and then guarantee that cylinder 2 works normally, the adjustable air supply channel 5 of air pressure regulator 6
Gas supply air pressure, guarantee matching carry out butterfly valve 1 test job；
Vacuum tank 8 is connected with butterfly valve 1；
Vacuum line 7 is connected with vacuum tank 8, air supply channel 5 respectively, and on vacuum line 7 sub- vacuum tank 8 to confession
It is disposed with vacuum generator 9, vacuum pumping valve 10 on gas channel 5, and then guarantees that the vacuum degree in vacuum tank 8 meets test and wants
It asks.
1 automatic testing method of butterfly valve are as follows: detection obtains the switching signal of magnetic switch 3, and then obtains 2 one, cylinder back and forth
T is compared by the time T of action cycle with the qualified time threshold value T0 of setting；
If T > T0 judges that butterfly valve 1 is unqualified；When butterfly valve 1 is unqualified, stop the detection of the butterfly valve 1, while into
Row alarm.
If T≤T0, continue to test, until the time T that ought continuously set number M acquisition is respectively less than and is equal to T0,
Then judge that butterfly valve 1 is qualified.
Specific process are as follows: signal is ' 1 ' after the magnetic switch of cylinder 2 is powered, and is set when the vacuum degree of vacuum tank 8 reaches
Definite value exhaust hood 2 acts, and movement moment magnetic switch signal is ' 0 ' and starts timing.Until cylinder 2 acts again, magnetic at this time
Property switch become ' 1 ' by ' 0 ' again and stop timing.Controller 41 can be automatic according to the switching signal of acquisition after one stroke
It calculates the 1 actuating length time of butterfly valve and all data is respectively stored in inside corresponding data register, wait controller 41
Acquisition calculates.Controller 41 will calculate the time value obtained compared with the progress data calculating of standard time value in real time, and it is qualified to calculate
Data be written data sheet, if there is unqualified data, controller 41 is issued an order immediately to be stopped timing and cuts off gas source to stop
It only tests, display 43 and alarm 44 prompt operator's 1 clamping stagnation test failure of butterfly valve at this time.During the test
If 1000 data are all qualified, it may be selected to generate data sheet after the completion of test so that the later period is checked.
