Description

Technical Field

[0001] This utility model relates to the technical field of non-coaxial rotary mechanical valves, and in particular to a gear-type non-coaxial rotary mechanical valve for gas water heaters. Background Technology

[0002] Gas water heaters generally have two types of valves: proportional valves for automatic thermostatic water heaters and mechanical knob valves for non-automatic thermostatic water heaters. Due to the limited internal space of the water heater, mechanical knob valves are usually installed at the bottom of the water heater, and the valve adjustment shaft is located at the lower right corner of the water heater, which greatly affects the appearance of the water heater after installation.

[0003] The existing mechanical knob regulating valve has its knob shaft directly integrated with the valve core, meaning the knob and valve core are coaxial. The knob is located in the lower right corner of the machine's casing, which affects the aesthetics of the overall industrial design. Furthermore, when users operate the knob with their right hand to adjust the heat level, their bodies are generally positioned to the left of the water heater. The observation window for viewing the flame is located in the center of the lower part of the machine, making it inconvenient for users to adjust the knob while observing the flame size. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a gear-type non-coaxial knob mechanical valve for gas water heaters, which allows the knob to be located in the lower center of the water heater casing without changing the overall internal structure and components of the water heater. This design is aesthetically pleasing and allows users to easily adjust the heat output with their right hand while observing the flame.

[0005] This utility model discloses a gear-type non-coaxial rotary mechanical valve for a gas water heater, comprising a gas line adapter, a first solenoid valve, and a second solenoid valve. The first solenoid valve is connected to the gas line adapter, and both the first and second solenoid valves are mounted on the inner wall of the gas water heater. The valve is characterized by further including a knob structure, a valve body, a valve core, and a valve core shaft. The second solenoid valve is mounted on the valve body, which is connected to the outer wall of the gas line adapter. The valve core is installed inside the valve body, and the valve core shaft is mounted on the valve core. A knob structure is provided at the end of the valve core shaft, which drives the rotation of the valve core shaft. By operating the knob structure, the user can easily drive the rotation of the valve core shaft. By changing the relative position of the knob's axis and the valve core through the knob structure, the knob position is located in the lower center of the water heater's outer casing without altering the overall internal structure and components of the water heater. This design is aesthetically pleasing and allows users to easily adjust the flame intensity with their right hand while observing the flame status.

[0006] Preferably, the knob structure includes a gear fixing plate, a first gear, a second gear, a third gear, a gear shaft, and a valve core shaft fixing plate. The gear fixing plate is installed on the inner wall of the gas water heater. The upper part of the valve core shaft rotates through the gear fixing plate. The first gear is installed at the front end of the valve core shaft. The second gear is rotatably installed on the outer wall of the gear fixing plate. The third gear is installed on the outer wall of the gear shaft. The gear shaft is rotatably installed on the gear fixing plate. The first gear, the second gear, and the third gear mesh with each other. By rotating the gear shaft, the operator causes the gear shaft to drive the valve core shaft to rotate through the meshing of the third gear, the second gear, and the second gear, thereby controlling and adjusting the gas valve body and the valve core, so that the knob position is located in the lower center area of ​​the water heater casing.

[0007] Preferably, the first gear and the third gear are set to have the same diameter, and the second gear is set to have a different diameter or the same diameter; by controlling the ratio of the diameters of the first gear, the second gear and the third gear, the rationality of torque transmission is improved and the ease of operation is enhanced.

[0008] Preferably, it also includes sheet metal support fasteners, which are installed on the outer wall of the first solenoid valve and the inner wall of the gas water heater. By setting sheet metal support fasteners to support and fix the first solenoid valve, the cantilever structure of the existing gas valve, which is fixed by a single support foot on the left side, is improved, enhancing the structural reliability of the water heater during transportation and reducing the risk of breakage and gas leakage due to unreasonable local stress on the mechanical valve.

[0009] Preferably, it also includes a knob, which is mounted on the front end of the gear shaft and is located on the outer wall of the gas water heater; the operator controls the mechanical valve by rotating the knob.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by operating the knob structure, the operator can easily drive the rotation of the valve core shaft. By changing the relative position of the knob axis and the valve core through the knob structure, the knob position is located in the lower center of the water heater casing without changing the overall internal structure and components of the water heater. This not only conforms to the aesthetics of the general public, but also makes it convenient for the user to adjust the firepower with their right hand while observing the flame status.
