Technical field
The utility model relates to city rail vehicle and rises the bow system, and particularly a kind of city rail vehicle rises the bow system with automatic conversion hysteria.
Background technology
At present, the liter of domestic city rail vehicle bow air feed as shown in Figure 1, is provided with manual three-way valve 7 in the system, be close stance under its normal circumstances, when the air pressure that does not have the artificial foot pump 11 of electricity employing rises bow, must operate the handle of manual three-way valve 7 earlier to opening the position; Must be when automatically controlled with the handle of manual three-way valve 7 to close stance, otherwise automatically controlled electromagnetic valve 2 can not be controlled the air pressure of being responsible for wind regime 10 and is used for normally rising bow and falling bow.
Automatically controlled falling under the arciform attitude has pressure if be responsible for the air pressure of wind regime 10, in case the handle of maloperation manual three-way valve 7 to opening the position then will cause and unexpectedly rise bow, thereby has stayed potential safety hazard to system.
The utility model content
At above-mentioned prior art, the utility model aims to provide a kind of city rail vehicle and rises the bow system with automatic conversion hysteria, it can realize the foot-operated automatic conversion that rises bow to automatically controlled liter bow of city rail vehicle, and automatically controlled falling under the arciform attitude, guarantees the maloperation failure to the safe side of hand valve.
For achieving the above object, the basic technical scheme that the utility model is taked is: the automatic conversion hysteria of a kind of city rail vehicle rises the bow system, comprise foot-operated bow pipeline and the automatically controlled liter bow pipeline of rising, should foot-operatedly rise the bow pipeline and comprise the hand valve that is communicated with foot pump, this automatically controlled liter bow pipeline comprises and is responsible for the electrically-controlled valve that wind regime is communicated with that this hand valve is communicated with pantograph through Pneumatic reversal valve, shuttle valve one end; This electrically-controlled valve is communicated with pantograph through the other end of one way sequence valve, shuttle valve; The mouth of this one way sequence valve is communicated with the control pressure chamber of Pneumatic reversal valve, and the response pressure of this one way sequence valve is higher than the liter bow operation pressure of this pantograph.
The mouth of described one way sequence valve and hand valve also is connected with compression indicator.
Described electrically-controlled valve is automatically controlled two position three-way valve, described hand valve be normal open from homing position type threeway push buttonvalve, described Pneumatic reversal valve is the gas control four-way cock.
Described compression indicator is the crosspointer compression indicator.
2 delivery ports of described gas control four-way cock have 1 to be communicated with atmosphere.
Principle of work of the present utility model is described as follows: do not rise bow by the foot-operated bow pipeline that rises when electrically-controlled valve has electricity, produce air pressure by foot pump, make pantograph rise bow through hand valve, Pneumatic reversal valve and shuttle valve one end, can observe the pressure size by compression indicator simultaneously.Can stop to ride if will fall bow this moment, presses the button of hand valve, makes a liter bow pipeline air draft fall bow, and release button then stops air draft.
When electrically-controlled valve gets when electric, the electrically-controlled valve commutation rises the bow operation pressure in case be responsible for wind regime pressure greater than pantograph, then one way sequence valve conducting is responsible for wind regime and is entered the shuttle valve other end, controls the Pneumatic reversal valve commutation simultaneously, the exhaust of foot pump air pressure, hand valve were also lost efficacy simultaneously; When being responsible for wind regime air pressure greater than foot pump air pressure, the shuttle valve commutation rises pantograph by being responsible for wind regime; During the electrically-controlled valve outage, be responsible for wind regime and end, rise bow pipeline Pneumatic pipe cleaner and cross check valve and electrically-controlled valve air draft.Pneumatic reversal valve resets.
The automatic conversion hysteria of city rail vehicle described in the utility model rises the bow system, electrically-controlled valve get electric, be responsible for the automatic conversion that can realize after wind regime pressure reaches certain value that foot-operated extremely automatically controlled liter bends, and under automatically controlled state, the button of hand valve is inoperative, the insecurity of having avoided artificial incorrect operation to bring.
