Abstract
A water intake automatic switching device of a carriage water tank which is suitable for railway transportation uses a mechanical controlling hydraulic water valve to realize the control of the water level of the water tank, and can assure that the water intake pipe is closed when the water level of the railway carriage is high and opened when the water level is low.
Description
Technical field
The utility model relates to a kind of passenger train water tank water intake recloser, can guarantee that especially suction culvert when the passenger train cistern water level is in a high position closes the method that suction culvert is opened when being in low level with cistern water level.
Background technology
At present, the passenger train water tank does not have automatic water inlet switch device, and whether the passenger vehicle water tank is filled is to have anhydrous overflowing to judge with drain hose.Drain hose has water to overflow, and the expression water tank is filled; Drain hose is anhydrous to be overflowed, and the expression water tank is not filled.The easy like this great lot of water resources waste that causes the water process, and the water on the roadbed that leaks in a large number in the winter time also can freeze, and brings potential safety hazard to train operation.
Summary of the invention
There is not the water inlet recloser in order to overcome existing passenger train water tank, the deficiency that causes water process great lot of water resources to leak, the utility model provides a kind of passenger train water tank water intake recloser, this device can realize that water tank fills back SELF CL suction culvert, and drain hose does not have leaked water.
The technical scheme that its technical matters that solves the utility model adopts is made up of main valve and priority valve two parts.Main valve is set on suction culvert, and the main valve water inlet links to each other with the main valve plug upper and lower cavity, and water outlet is connected with water tank.The main valve plug epicoele is communicated with the priority valve water inlet by the control mouth.Priority valve is installed on the water tank, and the priority valve ball float of its keying state in being in water tank just controlled by liquid level, and the priority valve water outlet is communicated with water tank.When liquid level was lower than setting value, priority valve ball float decline priority valve was opened, and when liquid level was higher than setting value, priority valve ball float rising priority valve was closed.Priority valve is opened when high water tank is lower than setting value, and the valve core of main valve upper cavity pressure is released through priority valve, and upper cavity pressure is less than following cavity pressure, and valve core of main valve is opened under this differential pressure action, and coolant inlet pipe is in opening, and water inlet flows to water tank through the main valve outlet; Priority valve is closed when high water tank is higher than setting value, and valve core of main valve upper and lower cavity equilibrium of pressure, valve core of main valve are under the effect of retracing spring power and close, and coolant inlet pipe is in closed condition.
The beneficial effects of the utility model are, can make the passenger train water tank water intake just realize automatic switch with high water tank, and coolant inlet pipe was in opening when high water tank was lower than setting value, and coolant inlet pipe was in closed condition when high water tank was higher than setting value.Liquid level signal is only adopted in the switching of water tank water intake main valve, and is simple in structure.

The specific embodiment
In Fig. 1, coolant inlet pipe (7) is provided with main valve (2) on the road, and main valve (2) water inlet links to each other with valve core of main valve (4) epicoele by passage a, and main valve (2) water outlet (6) is connected with water tank (9).Valve core of main valve (4) epicoele is communicated with priority valve (8) water inlet by control mouthful (5).Priority valve (8) is installed on the water tank (9), and priority valve (8) water outlet is communicated with water tank (9); The priority valve ball float of priority valve (8) keying state in being in water tank (9) just controlled by liquid level.When liquid level was lower than setting value, the priority valve ball float descended, and priority valve (8) is opened; When liquid level was higher than setting value, the priority valve ball float rose, and priority valve (8) is closed.When high water tank is lower than setting value, priority valve (8) is opened, valve core of main valve (4) upper cavity pressure is released through priority valve (8), the upper cavity pressure of valve core of main valve (4) is less than following cavity pressure, valve core of main valve (4) is opened under this differential pressure action, main valve (2) is in opening, and water inlet flows to water tank (9) through main valve (2) water outlet (6); When high water tank was higher than setting value, priority valve (8) was closed, and valve core of main valve (4) upper and lower cavity equilibrium of pressure, valve core of main valve (4) are under retracing spring (3) power effect and close, and main valve (2) is in closed condition.
In embodiment illustrated in fig. 2, priority valve (8) adopts rotary reversing valve.By being in the keying of the ball float control priority valve (8) in the water tank (9).When liquid level was lower than setting value, the priority valve ball float descended, and priority valve (8) is opened; When liquid level was higher than setting value, the priority valve ball float rose, and priority valve (8) is closed.When high water tank is lower than setting value, priority valve (8) is opened, valve core of main valve (4) upper cavity pressure is released through priority valve (8), the upper cavity pressure of valve core of main valve (4) is less than following cavity pressure, valve core of main valve (4) is opened under this differential pressure action, main valve (2) is in opening, and water inlet flows to water tank (9) through main valve (2) water outlet (6); When high water tank was higher than setting value, priority valve (8) was closed, and valve core of main valve (4) upper and lower cavity equilibrium of pressure, valve core of main valve (4) are under retracing spring (3) power effect and close, and main valve (2) is in closed condition.
In the embodiment shown in fig. 3, priority valve (8) adopts motor-driven change-over valve.By being in the keying of the ball float control priority valve (8) in the water tank (9).When liquid level was lower than setting value, the priority valve ball float descended, and priority valve (8) is opened; When liquid level was higher than setting value, the priority valve ball float rose, and priority valve (8) is closed.When high water tank is lower than setting value, priority valve (8) is opened, valve core of main valve (4) upper cavity pressure is released through priority valve (8), the upper cavity pressure of valve core of main valve (4) is less than following cavity pressure, valve core of main valve (4) is opened under this differential pressure action, main valve (2) is in opening, and water inlet flows to water tank (9) through main valve (2) water outlet (6); When high water tank was higher than setting value, priority valve (8) was closed, and valve core of main valve (4) upper and lower cavity equilibrium of pressure, valve core of main valve (4) are under retracing spring (3) power effect and close, and main valve (2) is in closed condition.
