Abstract
The utility model relates to an electromagnetic optical combined door pump, which is particularly used to control the starting-up and shutdown for a motor coach door. The utility model is formed by combination of a door pump, a main valve and an electromagnetic pilot valve, wherein, a piston rod in the door pump is connected with the door; the main valve and the electromagnetic pilot valve are combined into a whole to be fixed on a rear end cover of the door pump. The powering-on or powering-off of the electromagnetic pilot valve can control the flow direction of air entering into the door pump to realize the starting-up and shutdown movements for the motor coach door. Compared with structural form of adopting a direct operated electromagnetic pilot valve to control the flow direction of the air entering into the door pump, the utility model has the advantages of low power consumption, small size and low failure rate.
Description
The utility model relates to a kind of electromagnetic pilot type composite door pump, particularly controls the electromagnetic pilot type composite door pump that the motorcoach car door opens and closes.
In the device that existing control motorcoach car door opens and closes, all form by a door pump and electromagnetic valve.The door pump connects car door, and when the piston rod in the door pump was reciprocating, car door did to open and close motion.The flow direction of solenoid control access door pump internal pressure gas, promptly when the electromagnetic valve dead electricity, the piston rod in the door pump stretches out and makes closing of the door; When electromagnetic valve gets when electric, the piston rod in the door pump is return and is made car door opening.The weak point of this device is, adopts the flow direction of the pressed gas in the direct-acting electromagnetic valve direct control access door pump, and the required power consumption of electromagnetic valve is bigger, and volume also increases thereupon, in use often takes place because of the long phenomenon that burns out coil current"on"time.
The purpose of this utility model provides a kind of electromagnetic pilot type composite door pump, and it has the advantage that volume is little, low in energy consumption, fault rate is low.
For achieving the above object, the utility model is made up of door pump, main valve and electromagnetic priority valve, the door pump is made up of the door pump housing, front and rear cover, piston rod and seal ring, front and rear cover is separately fixed at the rear and front end of a pump housing, piston on the piston rod is installed in the pump housing, its bar stretches out by front end cover and connects car door, and seal ring is installed on the piston; Main valve is by main valve body, main valve plug, form by spool, retracing spring, end cap and seal ring, main valve plug and be installed in the main valve body respectively by spool, end cap is fixed on the bottom of main valve body, main valve body is fixed on the rear side housing of a pump housing (1), ending between spool and the end cap and retracing spring is being housed respectively outside the main valve plug, have induction opening, deflation hole and two delivery ports on main valve body, two delivery ports communicate with door pump loculus and big chamber respectively; Electromagnetic priority valve is made up of coil, moving iron core, retracing spring, exhaust cap, static iron core, valve body, end cap and sealing member, the bottom of valve body is fixed on the top of main valve body, end cap is fixed on the valve body upper end, static iron core, moving iron core, retracing spring are installed in respectively in valve body and the end cap, coil is installed in the outside of moving iron core, exhaust cap is installed in the top of end cap, at the two ends of valve body, end cap, static iron core and moving iron core sealing member is housed respectively.When the coil in the electromagnetic priority valve get electric after, the pressed gas warp that enters from admission port ends the lower end of spool and the loculus of delivery port access door pump, gas in big chamber is discharged from deflation hole through another delivery port of main valve plug, and piston rod is return, and car door is promptly opened.Behind coil losing electricity, moving iron core is blocked exhaust cap by retracing spring, the pressed gas that enters from the main valve induction opening, one road access door pump loculus, another road enters the top of main valve plug through the static iron core of priority valve, main valve plug is moved down block deflation hole and opens by spool, the pressed gas that enters from induction opening again can by by the upper end of spool through the big chamber of delivery port access door pump.Because the area difference that gas acted on is stretched out piston rod, car door is promptly closed.
The utility model is owing to adopt electromagnetic priority valve to control the motion of main valve plug, to realize the flow direction of control access door pump internal pressure gas, compare with the version that adopts the gas flow of direct-acting electromagnetic valve control access door pump internal pressure, required power consumption can reduce greatly, and volume also can reduce thereupon; In addition, also can significantly reduce the burnout phenomenon that causes because of coil electrify time is long.
Provide embodiment of the present utility model and accompanying drawing below, and be described further in conjunction with the accompanying drawings.
