Accompanying drawing explanation
Fig. 1 is structure diagram of the present utility model.
Detailed description of the invention
A kind of electromagnetic valve reversing valve core position monitoring device, including pressure resistant type proximity switch 3, transition block 1, spool leading-off rods
2, control system,
Transition block is arranged between calutron and valve body, and transition block two ends are designed with seal face, meets and installs and electricity
Hydraulic oil seal requirement under magnetic reversing valve designs pressure；Transition block is provided with pilot hole；
Spool leading-off rods is arranged in the pilot hole of transition block, and one end is connected with one end of spool, one end and electromagnetism push rod
Can contact connect, the middle part of spool leading-off rods is provided with sensing step；
Pressure resistant type proximity switch is arranged in transition block, and sensitive surface connects with the sensing step of spool leading-off rods, pressure resistant type
The output cable access control system of proximity switch.
Transition block is provided with the installing hole of pressure proximity switch vertically disposed with pilot hole, and pressure proximity switch is contained in peace
In dress hole, the output cable of pressure resistant type proximity switch is arranged on outside installing hole.It is provided with sense between pressure proximity switch and installing hole
Answer face upper-lower position governor motion.Meet the hydraulic oil seal needs under solenoid directional control valve design pressure, meet pressure close to opening
Closing fixed installation, the sensitive surface position meeting pressure proximity switch is the most adjustable；When sensing step enters pressure proximity switch sense
In answering district, there is signal intensity in pressure proximity switch；Pressure proximity switch signal can be controlled system acquisition；
Control system includes that signal receives and controls electricity with processing system, alarm lamp and/or buzzer and operation output
Road.
Clear in order to state, it is assumed that after spool leading-off rods sensing table top enters pressure resistant type proximity switch induction zone, pressure resistant type
Proximity switch output signal " 1 "；Otherwise output signal " 0 ".This electromagnetic valve be three-position electromagnetic reversal valve be A, O, B tri-respectively
Position, is mounted with two set spool monitoring devices, when No. 1 calutron obtains electric, and No. 2 calutrons are in power failure state, and No. 1 electromagnetic installing
The electromagnetism push rod put promotes spool leading-off rods and spool to move to right to B location, the now spool leading-off rods sense of No. 2 spool monitoring devices
Answering table top to enter the induction zone of pressure resistant type proximity switch, pressure proximity switch output signal " 1 " is arrived by controlling system acquisition, such as control
System acquisition processed is " 0 " to output signal, then logic thinks that spool does not arrive B location, is stuck in other position, so sending report
Alert, it is possible to carry out timely termination of pumping with pump operated and the interlocking of other operation logic or stop other operation, to avoid as harm
Occur.
When No. 2 calutrons obtain electric, No. 1 calutron promotes valve for power failure state, the electromagnetism push rod of No. 2 calutrons
Core leading-off rods and spool move to right to location A, and now the spool leading-off rods sensing table top entrance pressure resistant type of No. 1 spool monitoring device connects
The induction zone of nearly switch, pressure proximity switch output signal " 1 " is arrived by controlling system acquisition, as control system collects output letter
Number be " 0 ", then logic thinks that spool does not arrive location A, is stuck in other position, so sending warning, it is possible to pump operated
And the interlocking of other operation logic carries out timely termination of pumping or stops other operation, to avoid as harm generation.
When 1 and No. 2 calutron is all in power failure state, spool return under the action of the spring in i.e. O position, position, spool band
Outside the induction zone of the pressure resistant type proximity switch that the spool leading-off rods reset of dynamic 1 and No. 2 spool monitoring device is at correspondence, 1
Arrived, as control system does not gather by controlling system acquisition with the pressure proximity switch output signal " 0 " of No. 2 spool monitoring devices
To corresponding signal or pressure proximity switch output signal show spool at location A or B location, then logic thinks that spool does not has
It is reset to O position, is stuck in other position, so sending warning, it is possible to carry out with pump operated and the interlocking of other operation logic
In time termination of pumping or stop other operation, occurs for harm avoiding.
The function form of two solenoid directional control valves does not has O position, installs and uses ibid；If equipment controls to have only to prison
A set of spool monitoring device the most only need to be installed in one position of side valve core, installs and uses ibid.
Above-mentioned warning includes alarm lamp and buzzer, it is simple to operator receive warning in time.
By installing and using on solenoid directional control valve, effectively avoid the valve caused because of card valve or other reason
The infringement that the equipment that core causes when cannot put in place cannot stop action or other fault causes.
