Model utility content
In order to achieve the above object, solve the destabilization problems of longer testpieces, the utility model proposes a kind of solenoid valve control circuit, the control signal that coordinated loading control system exports can be amplified, and complete in air test, problem testing ground being installed additional the integrated of circuit and avoid customization cable to reequip.
The utility model solenoid valve control circuit, be arranged between control system and pressurized strut, comprise control signal input end, DC voltage input end and multiple DC voltage output end, described control signal input end is the voltage input of described control system, it connects relay, relay acts on switch, and switch-linear hybrid is between VDC with multiple voltage output end in parallel.
Preferably, tutorial light is provided with between described control signal input end and the first relay.
In such scheme preferably, described tutorial light is in parallel with described first relay.
In such scheme preferably, fus is in series with after multiple voltage output end parallel connection.
In such scheme preferably, independent switch is in series with respectively before multiple voltage output end parallel connection.
In such scheme preferably, relay is 2 drive 2 closed form relays.
Whole circuit has the functions such as input, output, instruction, protection.When coordinated loading control system normally also prepares to test, tutorial light is bright, control box accepts the instruction that control system sends, when external large power supply continued power, after the relay adhesive of circuit part can be controlled in case, the normal voltage provided by external large power supply outputs to control box output through the fus of control circuit, by the connection of solenoid valve cable, fluid-control one-way solenoid valve in pressurized strut in hydraulic protecting module is opened, and pressurized strut can normally work; If when electromagnetic valve instruction is low level, then the tutorial light of control box front panel does not work, and represents the non-Access Control input signal of cabinet, does not possess the ability of output voltage.Fluid-control one-way solenoid valve in pressurized strut cannot be opened, and pressurized strut cannot be worked.
The utility model by former control voltage is carried out control relay adhesive switch as input signal, thus can re-enter the VDC of 24v to pressurized strut, effectively prevent because of the decay of primary voltage the impact that pressurized strut produces.
