Abstract
The utility model belongs to the field of boilers, particularly relates to design of a water boiling cavity of an electric water boiler for a train, and aims at providing an electric water boiler automatic water-draining device for the train. The electric water boiler automatic water-draining device for the train is low in cost without needing manual operation. The electric water boiler automatic water-draining device for the train comprises the water boiling cavity, a heating element, a water inlet valve and a water outlet valve. The water inlet valve and the water outlet valve respectively are a water inlet electromagnetic valve and a water outlet electromagnetic valve. The water inlet electromagnetic valve and the water outlet electromagnetic valve are controlled by a circuit. A sensor which is used for detecting a water level of the water boiling cavity is installed at the position where the water boiling cavity is arranged, and the sensor is connected with the water inlet electromagnetic valve and the water outlet electromagnetic valve through the circuit. The electric water boiler automatic water-draining device for the train is reliable in performance, and low in cost and does not need manual operation.
Description
Technical field
This is novel belongs to the boiler field, relates in particular to train with the boiling water chamber design of electric water boiler.
Background technology
Boiler applies on passenger train widely, to satisfy passenger and crew member's drinking-water demand.But in use exist three shortcomings: the 1st, can not the cold water in the boiling water chamber be drained before using, boiler can not provide boiling water within a very long time of beginning; The 2nd, need to be manually the water in boiler boiling water chamber be drained, increased the complexity of operation; 3 must bring staff's extra work amount, are unfavorable for increasing work efficiency.
The utility model content
The utility model purpose be to provide a kind of with low cost, need not manually-operated train electric water boiler self-draining arrangement.
This novel mentality of designing is that boiler is when starting working, first every transducing signal is carried out self check, also have residual water to exist in boiler boiling water chamber if detect, open drain solenoid valve and carry out draining, when signal being detected and satisfy original state, time-delay is turn-offed drain solenoid valve after a period of time, after guaranteeing that cold water in the boiling water chamber is drained, begins circulation and produces hot water.The method and equipment have solved the problem that needs artificial drainage, have improved the operating efficiency of boiler, have realized Automatic Control truly.Simplify user's operating procedure, improved operating efficiency.
Concrete technical scheme is: a kind of train electric water boiler self-draining arrangement, comprise boiling water chamber and heating element heater, bottom, boiling water chamber is provided with into and out of water valve, above-mentioned is the water-in and water-out magnetic valve of being controlled by circuit into and out of water valve, in above-mentioned boiling water chamber, setting position is equipped with to detect the sensor of boiling water chamber middle water level, and the sensor and water-in and water-out magnetic valve are by the circuit control connection.
The utlity model has dependable performance, with low cost, need not manually-operated, be easy to regulate, energy savings, the advantages such as human nature service satisfy the society consumer demand.
Description of drawings
Fig. 1 is this new structure schematic diagram.
The specific embodiment
During this novel use, at first boiler energising work, drainage arrangement starts, detecting sensor SW5 signal, if when water level surpassed the SW5 position, entering water electromagnetic valve was closed, drain solenoid valve is opened draining; Arrive the SW5 position when following when drainage arrangement detects water level, timer begins to clock, and after time-delay a period of time t, closes drain solenoid valve.If when drainage arrangement starts, when water level being detected lower than the SW5 position, open the drain solenoid valve draining, regularly clock simultaneously, after time-delay a period of time t, close drain solenoid valve.After remaining water drained in the boiling water chamber, boiler began periodic duty, supplies continuously boiling water.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (1)
1. train electric water boiler self-draining arrangement, comprise boiling water chamber and heating element heater, bottom, boiling water chamber is provided with into and out of water valve, it is characterized in that: above-mentioned into and out of the water-in and water-out magnetic valve of water valve for being controlled by circuit, in above-mentioned boiling water chamber, the pre-position is equipped with to detect the sensor of boiling water chamber middle water level, and the sensor and water-in and water-out magnetic valve are by the circuit control connection.
