In addition, the utility model is provided with leakage preventer, can prevent effectively that from there is leakage problem in supply channel, when perhaps having people's malice to use terminal watering equipment, and the waste of water resources.
Description of drawings
Fig. 1 the utility model structural representation.
As shown in Figure 1, water tank 1, liquid-level switch 2, water pump 3, filter 4, bypass valve 5, water supply electromagnetic valve 6, drain solenoid valve 7, sense water switch 8, anti-leak switch 9, drain solenoid valve 10, terminal watering equipment 11, vent valve 12.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, pump control unit in the rail vehicle water supply system described in the utility model, comprise: a water tank 1, a water pump that is used for supplying water on car 3 is set in supply channel, at the water outlet place of water tank 1 filter 4 is set, filter 4 is used for the water that filter cleaning enters water pump 3.
Be provided with a liquid-level switch 2 at water tank 1 by the position that reaches the bottom, on the water outlet of water tank 1 and the supply channel between the water pump 3, also be provided with a sense water switch 8, liquid-level switch 2 is used for detecting the liquid level of water tank 1, whether sense water switch 8 is used for detecting supply channel has water to flow, no matter be that water tank 1 the inside does not have water, still feeling water switch 8 detects less than water, the electric control unit of system all can receive the anhydrous signal that is sent by liquid-level switch 2 and sense water switch 8, thereby control of pump 3 quits work, and prevents that water pump 3 from moving under anhydrous state.
When the terminal watering equipment on the car 11 uses, water pump 3 will be worked, and on car, supply water, but when the terminal watering equipment 11 on the car is closed, if this moment, water pump 3 quits work, so, the water in the supply channel will be in static state, if in the winter time, the water that remains static in the supply channel will freeze so, thereby influences the water on the car.Water in supply channel freezes, must guarantee that the water in the supply channel can be in mobile state all the time, like this, will guarantee water pump 3 energy continuous firings, so the utility model has added a bypass line between the water outlet of water pump 3 and water tank 1, be provided with a bypass valve 5 on bypass line, bypass valve 5 has certain cracking pressure.After terminal watering equipment 11 is closed on the car, because water pump 3 is also working on, so water pump 3 constantly pumps water, hydraulic pressure in the supply channel is constantly raise, after the cracking pressure that reaches bypass valve 5, bypass valve 5 is opened, and the water in the supply channel is back in the water tank, so just can guarantee water pump 3 continuous firing always.According to the water supply capacity of the water pump 3 of current track vehicle, the cracking pressure of bypass valve 5 is set at 120KPa, can make the stable water pressure of supply channel the inside, remains on 120KPa always.
When system's dead electricity, when water pump 3 can not be worked, at this moment, in supply channel, also have some waters, in the time of in the winter time, these waters also can cause supply channel to freeze, so the water in the supply channel must be bled off.In order to address this problem, the utility model is provided with a water supply electromagnetic valve 6 on the water outlet of water tank 1 and the supply channel between the water pump 3, be used to control the switching of supply channel, is normally closed solenoid valve, when water pump 3 work, locate electric conducting state, terminal watering equipment 11 supplies water on car.
Also between the water outlet of water supply electromagnetic valve 5 and water tank 1, increased a discharge pipe line, a drain solenoid valve 7 is set on discharge pipe line, drain solenoid valve 7 is a normally open solenoid valve, when water pump 3 work, locate electric closed condition, at this moment, discharge pipe line disconnects, when system's dead electricity, drain solenoid valve 7 dead electricity conductings, the water in the supply channel will be discharged outside the car by discharge pipe line.For the water in the supply channel is more prone to discharge, second drain solenoid valve 10 is set in supply channel, it also is a normally open solenoid valve, conducting after system's dead electricity is discharged the water in the supply channel outside the car.
The utility model is provided with an anti-leak switch 9 on the pipeline between the terminal watering equipment 11 on water pump 3 water outlets and the car, be used for detecting supply channel and continue streamflow regime, and then judge whether terminal watering equipment 11 has leakage phenomenon, signal is connected between anti-leak switch 9 and the electric control unit.
When anti-leak switch 9 detects the continuous effluent time when being higher than set time (generally can be set at 3 minutes), anti-leak switch 9 will send leakage signal to the electric control unit on the car, electric control unit will control of pump 3 quit work, simultaneously, health department on the car is unavailable, electric control unit is reported to the police, after the Recovery time of setting, and the system recovery proper functioning.
Also be provided with one in the electric control unit and be used for the manual reseting device that control system is recovered proper functioning, after the system recovery proper functioning, the time that anti-leak switch 9 detects continuous effluent once more is higher than set time (3 minutes), will send leakage signal once more, then electric control unit will judge that pipeline has leakage, thereby electric control unit control of pump 3 quits work, health department on the car is unavailable simultaneously, electric control unit is reported to the police, and system can not resume work automatically again, carry out hand reset but need the staff to operate manual reseting device (button resets or power-off restoration), proper functioning could be recovered by system.If truly have leakage in the pipeline, will wait until that the staff overhauls after, hand reset, system resumes work again, effectively avoided because pipeline leakage, or artificial malice is used the waste of the water resources that is caused.
As mentioned above, given in conjunction with the accompanying drawings and embodiments scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
