Abstract
Disclosed is a water-feeding automatic closing device for railway passenger trains, which enables a valve, a liquid level switch, a signal feedback device and a rapid joint to be connected in sequence to form a water supply and backwater opening and closing system so as to realize water level control of a water tank. The water supply automatically stops after the completion of water feeding and the water-feeding process is fast without water leakage.
Description
Technical field
The utility model relates to a kind of water self closing device of going up, and can guarantee that especially the passenger train water-feeding process do not have the method for supplying water that leaks.
Background technology
At present, the water method is on the passenger train general-duty: the surface water supply pipe is directly received the passenger vehicle tank inlet pipe supply water, treat that passenger vehicle tank drains Guan Youshui overflows, the expression water tank is filled, stops to supply water, and surface water supply pipe and passenger vehicle tank inlet pipe are thrown off.Because whether whether surface water supply stops, be to have water to overflow with passenger vehicle tank drains pipe to be as the criterion.Like this, when water supply is finished, overflow water in residuary water in the coolant inlet pipe and the drain hose, on the roadbed with the railway that leaks in a large number, cause water resource waste; The water that leaks in the winter time on the roadbed also can freeze, and brings potential safety hazard to train operation.
Summary of the invention
In order to overcome existing the leaking of water method great lot of water resources of going up, the utility model provides a kind of passenger train water-feeding self closing device, and this device can be realized stopping automatically after water tank is filled supplying water, and water inlet pipe and water outlet pipe does not have leaked water.
The technical scheme that its technical matters that solves the utility model adopts by on the car and car under two parts form.Represent passenger vehicle on the car, expression platform under the car.
The water inlet start-stop system is formed by main valve (5), liquid level switch (8) two parts in car top.Main valve (5) is installed on the suction culvert on the car (6), and liquid level switch (8) is installed on the water tank (7).According to the height of water tank (7) water level,, utilize the keying of pressure signal or electric signal control main valve (5) by liquid level switch (8).When water tank (7) when water level is lower than setting value, main valve (5) is often opened; When water level was higher than setting value, main valve (5) was normally closed.
The car lower part connects to form water supply, water recovery apparatus with feed cock (1), signal feedback device (2), quick coupling (3), rubber tube (9), control housing (10), backwater valve (11), low flush tank (13).Car is got on the bus down and is linked by coolant inlet pipe (4) on quick coupling (3), rubber tube (9) and the car, and main valve on car (5) is in opening, supplies water; Main valve on car (5) is in closed condition, water inlet can't be flowed between feed cock (1) and main valve (5), pressure raises, signal feedback device (2) sends signal, through control housing (10) feed cock (1) is closed, backwater valve (11) is opened, and stops to supply water, and makes the water that remains in the rubber tube (9) flow back to low flush tank (13) through backwater valve (11).
When supplying water on to car under the car, through quick coupling (3) with car under on water supply rubber tube (9) and the car coolant inlet pipe (4) connect, open feed cock (1), backwater valve this moment (11) is in closed condition.Water inlet is by feed cock (1), through signal feedback device (2), rubber tube (9), coolant inlet pipe (4), to main valve (5).If water tank (7) is when water level is lower than setting value, main valve (5) is in opening, and water inlet flows into water tank through suction culvert (6).Along with the inflow of water inlet, water tank (7) water level raises, and when treating that water level is elevated to setting value, liquid level switch (8) sends signal, and main valve (5) is closed.Water inlet stops to flow between feed cock (1) and main valve (5), pressure raises, signal feedback device (2) sends signal, through control housing (10) feed cock (1) is closed, backwater valve (11) is opened, make the water that remains in the rubber tube (9) flow back to low flush tank (13), throw off quick coupling (3), water process in the end through backwater valve (11).
After low flush tank (13) was filled, liquid level switch (12) sent signal, started water pump (14) through control housing (10), and the water in the low flush tank (13) is discharged.
The beneficial effects of the utility model are, the passenger train water-feeding process do not had fully leak, and water on the SELF CL
Device, alleviating the operation element amount, the conserve water resource is eliminated the traffic safety hidden danger that causes because of outer sluicing freezed in winter.
