Below with reference to the attached drawing of specification, specific embodiment of the present utility model is further described, makes this reality With novel technical solution and its benefits are clearer.It is exemplary for describing embodiment below with reference to attached drawing , it is intended to it explains the utility model, and should not be understood as limiting the present invention.

The gas instantaneous water heater as shown in Figure 1, a kind of leak is cut off the water supply, 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, the master controller 3 are that power supply lane controller is protected in the leakage of gas heater ontology.

Wherein, as shown in Figure 2 and Figure 3, the leak water detdction box 1 is mounted in the bottom cover lower plate of the gas heater. The leak water detdction box 1 includes: water storage tank 1-1, electrode pressing plate 1-2 and fixing screws 1-3, is set in the water storage tank 1-1 There is two root posts 1-4, one electrode pressing plate 1- is fixed with by the fixing screws 1-3 at the top of each column 1-4 2.When the water surface in water storage tank 1-1 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.

As shown in figure 4, the water proportioning valve 2 includes: the valve body 2-3 with water inlet 2-1 and water outlet 2-2, it is mounted on institute The adjusting spool 2-4 that the water inlet 2-1 and water outlet 2-2 can be separated in valve body 2-3 is stated, the adjusting spool is driven The stepper motor 2-5 of 2-4, and the water flow sensor 2-6 that is mounted on the valve body 2-3 and for detecting the temperature of water temperature Sensor 2-7.The water proportioning valve is other than having water flow detection, temperature detection and water flow and adjusting, by increasing stepper motor 2-5 Adjusting step number, rotation adjusting spool 2-4 block seal 2-8, so that water proportioning valve is had cutoff function, can close water route realization It cuts off the water supply.

As shown in figure 5, in actual work, when gas instantaneous water heater works normally, leak water detdction box 1 is anhydrous, electrode Circuit is open circuit；When gas instantaneous water heater leak, leak water detdction box 1 fills water, telegraph circuit access, master controller 3 Water leakage is received, the water proportioning valve 2 with cut-off is controlled and inlet pipeline is truncated, water route is closed and cuts off the water supply；Same main control The power-off of device 3 is no longer powered for other components, and gas instantaneous water heater stops working, and display is reminded with Times failure.

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.
