Problems solved by technology

[0004] From the above, it can be seen that the thermostatic valve used for gas water heaters tends to cause the flow of hot water to become smaller during temperature adjustment, resulting in repeated flameout and ignition problems in gas water heaters; gas water heaters have repeated flameouts and ignitions when the flow rate is small, resulting in intermittent cold and hot water. phenomenon, very inconvenient

Embodiment 1

[0039] refer to Figure 1 to Figure 5 , in this embodiment, the regulating spool adopts a switch spool, which is provided with a water inlet 31 and a water outlet 32, the water inlet 31 communicates with the secondary cold water passage 15, and the water outlet 32 ​​communicates with the first constant temperature water passage 16, A small hole 16a is provided between the first constant temperature water channel 16 and the second constant temperature water channel 17 to realize the communication between the two. By adjusting the second handwheel 39, the opening of the water inlet 31 can be adjusted, including half-open, fully open and closed, so as to switch between different gear positions.

[0040] In this embodiment, the regulating spool can be set to three gears, namely spring and autumn gears, summer gear and winter gear, and the corresponding opening degrees of the water inlet 31 are half open, fully open and closed. The specific working principle is as follows:

Embodiment 2

[0046] refer to Figure 6 to Figure 11 , in this embodiment, the regulating spool includes a switching spool and a water mixing module 34 . The switching valve core is provided with a water inlet 31 and two water outlets 32 , and the water inlet 31 communicates with the secondary cold water channel 15 . The water mixing module 34 is fixed on one end of the switch valve core, and is provided with two water mixing channels, which are respectively a normal pressure water mixing channel 35 and a pressurized water mixing channel 36, and one end of the two water mixing channels is connected to the two water outlets of the switching valve core. 32 are communicated one by one, and the other end communicates with the second constant temperature water channel 17, and the water mixing module 34 is provided with a gap 37 communicating with the first constant temperature water channel 16, and the gap 37 communicates with the two mixing water channels.

Abstract

A constant-temperature water outlet structure special for a gas water heater comprises a valve body, a thermostatic cartridge and a regulating cartridge. The valve body is provided with a hot water passage, a main cool water passage, an auxiliary cool water passage, a first constant-temperature water passage and a second constant-temperature water passage. The thermostatic cartridge is mounted in the valve body, and is communicated with the main hot water passage, the main cool water passage and the first constant-temperature water passage to realize mixing of cool water and hot water to output primary constant-temperature water. The regulating cartridge is mounted in the valve body and is communicated with the first constant-temperature water passage, the auxiliary cool water passage and the second constant-temperature water passage to control to start or stop mixing of cool water and hot water and output secondary constant-temperature water or primary constant-temperature water. The constant-temperature water outlet structure can prevent the gas water heater from the problem of frequent ignition due to frequent extinction caused by small flow of hot water, prevent temperature of outlet water from being unstable, and can meet people's requirements on water temperature at different seasons.

Description

technical field [0001] The invention relates to the field of constant temperature water outlet structures, in particular to a constant temperature water outlet structure dedicated to gas water heaters. Background technique [0002] At present, the working principle of the water-vapor linkage valve of the gas water heater is realized through a mechanical structure. When there is water flow through, the valve will open, thereby driving the push rod on the valve to move to push the gas valve. When the flow of water is greater, The greater the valve opening volume, the greater the gas output. [0003] Generally, the thermostatic valve used for gas water heaters needs to gradually reduce the hot water opening of the valve core when the temperature is lowered, resulting in a decrease in the hot water output of the gas water heater; when the hot water output of the gas water heater decreases Hours, due to the action of the water vapor linkage valve of the gas water heater, the gas...
