The control to pressure gas conveyed to a large cavity and a small cavity of a door pump is realized by switching on or off the power supply of the electromagnetic guide valve with small power, and thus the purpose of operating the opening and closing for the bus door is obtained.
Description
The utility model relates to a kind of electromagnetic pneumatic control valve of improved passenger door opening and closing.
Be used for the control of passenger door opening and closing at present, the pneumatic means that generally adopts two independent manual three-way valves of installing and straight ejector half electromagnetic valve to form, wherein manual three-way valve is as the prime control of pressure gas, straight ejector half electromagnetic valve is then by switching on and off the power supply of electromagnetic valve coil, controlled pressure make leave with rage to, the reciprocating motion of generator gate pump piston, again by the piston push rod drive transmission device, the opening and closing car door.
But above-mentioned car door opening and the control device of closing because two valves are discrete installation, carry out gas circuit by exterior line between two valves and connect, and the position is bigger so the The whole control device takes up space, debugging, maintenance trouble.And the loose pipe joint that shakes easily in the bus driving, make the pressure gas leakage, the reliability of influence door pump work.In addition, straight ejector half electromagnetic valve utilizes the electromagnetic force of hot-wire coil, directly inhales moving main valve plug, so power consumption is bigger, influences the application life of storage battery on the car.
The purpose of this utility model at first is to provide a kind of integrated combined type car door electromagnetic pneumatic control valve, be characterized in being combined in same valve body with hand-operated valve and electromagnetic valve are integrated, and in valve inner formation gas channels and input and output hole, make the car door electromagnetic pneumatic control valve after the improvement have compact conformation, Installation and Debugging make things convenient for advantage.
Next is ingredient---the electromagnetic valve of above-mentioned integrated combined type car door electromagnetic pneumatic control valve, change into by the pilot-type solenoid valve of small power electromagnetic pilot valve and main valve be combined into and replacing, obviously fall advantage of low power consumption thereby car door electromagnetic pneumatic control valve after the improvement is had again.
The utility model is achieved in that hand-operated valve and pilot-type solenoid valve is integrated is combined in the same valve body, by being arranged on pressure gas passage and the input and output hole in the valve body, realizes the control of moving towards of pressure gas.During use, hand-operated valve is pulled to " opening " position, if the small power electromagnetic pilot valve is in power failure state, the gas circuit blocking of then leading to this pilot valve, and, then pass through hand-operated valve inner chamber, gas main channel and delivery outlet by the pressure gas that input hole adds, be sent to a pump loculus, under the effect of pressure gas, the door pump piston is in reset position.After the small power electromagnetic pilot valve obtains electricity, inhale moving this valve core, make the pressure gas of hand-operated valve inner chamber enter small power electromagnetic pilot valve inner chamber through the gas main channel, lead to main valve through the gas passage branch road again, depress valve core of main valve and back down the main stop valve core,, be sent to the big chamber of a pump from delivery outlet so gas main channel upward pressure gas just directly enters the main valve inner chamber, the door pump piston just is under big chamber and the acting in conjunction of loculus internal pressure gas like this, and the pressure official post piston of generation leaves muscle-setting exercise.Move back and forth by small power electromagnetic pilot valve dead electricity or the door pump piston that obtains electric control, motor-driven through the transmission of piston push rod, close or open car door.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing 1 is the utility model " integrated combined type car door electromagnetic pneumatic control valve " structure cut-away view.
Referring to accompanying drawing 1, hand-operated valve, small power electromagnetic pilot valve, main valve is integrated is combined on the same valve body (1).Hand-operated valve is positioned at the left side of valve body (1), places side by side the small power electromagnetic pilot valve of assembling and the right side that main valve is positioned at valve body (1) with hand-operated valve.Pull manual valve handle (8) to " opening " position, at the elastic force that overcomes back-moving spring (7), depress hand-operated valve behind the spool (3), the pressure gas that is added by input hole (2) is through manual valve insertion (4), gas main channel (6), be sent to a pump loculus from delivery outlet (21), under the effect of pressure gas, the door pump piston moves to reset position, motor-driven through the transmission of piston push rod then, closed door.After small power electromagnetic pilot valve electromagnetic coil (10) obtains electricity, the electromagnetic attraction of electromagnetic coil (10) overcomes the elastic force of back-moving spring (12), electromagnetic valve core (11) moves up, make originally and to be got lodged in pressure gas on the gas main channel (6) by the small power electromagnetic pilot valve, through small power electromagnetic pilot valve inner chamber (13), gas passage branch road (14), only need a spot of pressure gas to act on the main valve plug (15), can overcome the elastic force of back-moving spring (20) and depress main valve plug (15) and back down main valve by spool (19), pressure gas on gas main channel so (6), inner chamber (17) through main valve is sent to the big chamber of a pump from delivery outlet (18).Thus, just under big chamber and the acting in conjunction of loculus internal pressure gas, the pressure official post piston of generation leaves muscle-setting exercise to the door pump piston, through the transmission mechanism of piston push rod, opens car door then.
If manual valve handle (8) is pulled to the off-position, hand-operated valve is blocked from the next pressure gas of air inlet (2) by spool (3), and then the no pressure gas of delivery outlet (21) exports a pump loculus to, and the gas main channel does not have pressure gas in (6) yet.Therefore, no matter the electromagnetic coil (10) of small power electromagnetic pilot valve electric or dead electricity, delivery outlet (18) does not equally have pressure gas yet and transfers to the big chamber of a pump.So the effect of pressure gas opposite house pump piston has not existed, the electromagnetic pneumatic control valve has lost closing of the door and control of turning ability.
(5), (9), (16) are respectively the steam vent of hand-operated valve, small power electromagnetic pilot valve, main valve in the accompanying drawing 1, as under back-moving spring (7), (12), (20) effect, spool (3), (11), (19) are in when blocking pressure gas operating mode, the exhaust passage of three valve pocket internal pressure gas is to guarantee the reliability of back-moving spring to the spool effect.
Above-mentioned integrated combined type car door electromagnetic pneumatic control valve, when pulling manual valve handle to the position of " opening ", as long as be switched on or switched off the power supply of small power electromagnetic pilot valve electromagnetic coil, the spool that acts on main valve with a spot of pressure gas gets final product the trend of controlled pressure gas at gas passage, realizes the opening and closing of car door.
Integrated combined type car door electromagnetic pneumatic control valve after the improvement, compact conformation, light and handy, the power consumption reduction, easy for installation of volume, hand-operated valve, the discrete installation of electromagnetic valve have in the past been overcome, weak point such as exterior line connects brought bulky, power consumption big, the debugging complicated, fault is many.
The utility model is specially adapted to the operation control that passenger door opens and closes, also applicable in the pneumatic basic controlling device of other electronic controls.
