As shown in Figure 1-Figure 3, a kind of leak is cut off the water supply gas heater, comprising: gas heater master controller 3, feature
It is, in the bottom of gas heater, setting is used to detect the leak water detdction box 1 of leak, on the water inlet pipe of gas heater
Normally closed cut-off valve 2 is set, the leak water detdction box 1 and the normally closed cut-off valve 2 all with the gas heater master controller 3
Connection.
When gas heater does not work, the inlet pipeline of gas heater is truncated in normally closed cut-off valve 2, is reached when not working
The purpose of preventing water leakage.When gas water heater working, 3 input current of gas heater master controller is normally closed to normally closed cut-off valve 2
Shut-off valve 2 is opened a way, and complete machine operates normally；When gas heater leak, leak water detdction box 1 feeds back water leakage to the combustion gas
Water heater master controller 3, at this moment, gas heater master controller 3 control 2 open circuit of normally closed cut-off valve, stop water inlet, reach
The purpose of preventing water leakage when work.
Wherein, the leak water detdction box 1 is mounted in the bottom cover lower plate of the gas heater.The leak water detdction box
Son 1 includes: water storage tank 1-1, electrode pressing plate 1-2 and fixing screws 1-3, and two root posts 1-4 is equipped in the water storage tank 1-1,
One electrode pressing plate 1-2 is fixed with by the fixing screws 1-3 at the top of each column 1-4.When in water storage tank 1-1
The water surface be more than water surface dead line, flood two electrode pressing plate 1-2, according to detection two electrode pressing plate 1-2 between change in resistance
Determine leak.
In other embodiments, the electrode pressing plate water level sensor substitution being arranged in water storage tank, is not limited to
The present embodiment.
For the installation convenient for water storage tank 1-1, it is equipped with flange 1-5 at the top of the water storage tank 1-1, in the flange 1-5
It is equipped with installation fixation hole 1-6.In the present embodiment, the flange 1-5 is flanging, and flange 1-5 and the water storage tank 1-1 are one
Forming structure.
The high-temperature water tank that the gas heater in work is encountered due to air is to be easy to produce condensed water, if do not stored up
Sink condenses water submerged electrode, it is most likely that cause to malfunction.The water of condensed water is much smaller than leak water, designs water storage tank,
When the water surface floods water surface dead line, master controller just receives signal, and water inlet pipe is closed in power-off, effectively avoids combustion gas heat
The malfunction of hydrophone master controller.
From the foregoing description of structures and principles it should be understood by those skilled in the art that, the utility model
It is not limited to above-mentioned specific embodiment, it is equal using the improvement of techniques well known and substitution on the basis of the utility model
The protection scope of the utility model is fallen in, the protection scope of the utility model should be limited by each claim and its equivalent
It.The part not illustrated in specific embodiment is the prior art or common knowledge.
