Embodiment 1
[0028] This preferred embodiment provides a water outlet and inlet valve assembly for a water heater. Such as figure 1 and figure 2 As shown, the valve assembly includes a housing 1 and a valve core 2 arranged in the housing 1; the upper part of the housing 1 is provided with a casing port 11 for drainage and air intake, and the lower part is provided with an air inlet 12 and a drain port 13 ; The casing port 11 is provided with a hollow air pipe 3; the valve core 2 includes two spherical structures with passages inside, the first spherical structure 21 is used to communicate or shut off the intake passage, and the second spherical structure 22 is used for Connect or shut off the water outlet channel. The first spherical structure 21 and the second spherical structure 22 are fixedly connected (forming a gourd-like structure).
[0029] The spool 2 is composed of two parts, one part is used to connect or shut off the intake passage and the other part is used to connect or sh...
Embodiment 2
[0036] This preferred embodiment provides a water outlet and inlet valve assembly for a water heater, the structure of which is basically the same as that of the first preferred embodiment. The valve assembly includes a housing and a valve core arranged in the housing; a sleeve port for drainage and air intake is provided on the upper side of the housing, and an air inlet and a water discharge port are provided on the lower side; the valve core includes two internal passages respectively The spherical structure, the first spherical structure is used to connect or shut off the air intake passage, and the second spherical structure is used to connect or shut off the water outlet passage.
[0037] The difference is that: the specific structure of the intake channel on the first spherical structure is not limited, and it only needs to realize the connection or closure of the intake channel when the valve core rotates to different angles; the connection between the first spherical s...
Embodiment 3
[0039] This preferred embodiment provides a water heater. Such as Figure 4 As shown, the water heater includes a casing 6, an inner tank 7 and the water outlet and inlet valve assembly as described in the preferred embodiment 1 or 2. The air pipe 3 and the water outlet hole 4 are located in the inner tank 7 , and the casing 1 and the valve core 2 are at least partly located outside the casing 6 .
