Embodiment Construction
[0037] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:
[0038] Such as figure 1 As shown, a train water supply device includes a clean water tank 1, a water tank I5, a water tank II6, and an injector 14.
[0039] The top of the clean water tank 1 communicates with the atmosphere to maintain normal pressure without pressure bearing requirements, so the clean water tank is light in weight.
[0040] The water tank I5 is connected to the clean water tank 1 through a water suction pipeline, and is used for temporarily storing the clean water flowing out of the clean water tank 1 . The water suction pipeline is used to transport the clean water from the clean water tank 1 to the water tank I5, and a water filter 7 and a two-way valve I8 are arranged on the water suction pipeline.
[0041] The water tank I5 and the water tank II6 are connected through an intermediate pipeline. There is a one-way valve I9 on...

The invention discloses a water supply device for a train and a control method thereof, comprising a clean water tank, a water tank I, a water tank II, an ejector, connecting pipelines and valve parts. The water tank is connected to the water tank II, the water tank II is connected to the water appliance through the water supply pipeline, and the upper part of the water tank I is connected to the vacuum port of the injector and the train air source through the evacuation pipeline and the water supply pipeline I respectively, The upper part of the water tank II is respectively connected to the atmosphere and the train air source through the exhaust pipeline and the water supply pipeline II; the water tank I is provided with a liquid level switch I and a liquid level switch II from top to bottom, and the water tank II There are liquid level switch III, liquid level switch IV and liquid level switch V from top to bottom; it can supply water uninterruptedly, reliable in operation, low in use and maintenance cost, and has no special pressure bearing requirements for the clean water tank, and can be installed at the bottom of the train as required.
Description
technical field [0001] The invention relates to a water supply device and a control method thereof, in particular to a train water supply device which utilizes compressed air for continuous water supply on a train. Background technique [0002] The train water supply system is used to provide clean water for train toilets, kitchens, electric boilers, etc. The traditional train water supply system generally adopts a large clean water tank at the bottom of the train and a small clean water tank on the top of the train. The water pump is used to pump the water from the large clean water tank at the bottom of the train to the small clean water tank on the top of the train. A method for supplying water from a small water tank to each water point. With the development of high-speed trains, in order to reduce the section of the train and lower the center of gravity of the vehicle, there is not enough space on the roof to place a small clean water tank that meets the needs. For th...
