Description

A valve body assembly of a household gas stove

technical field

The utility model relates to a valve body assembly of a gas stove.

Background technique

At present, what are generally used on gas cookers are manual cock valves, which need to manually adjust the amount of gas, and then control the size of the combustion firepower. The valve body with this structure has the problem of uneven flow curve, that is, the output flow is non-linear, and it is impossible to realize the simultaneous adjustment of the inner and outer ring flow of the cooker burner, which brings a very bad experience to the user. There are also plug valves on the market that control the rotation through stepper motors, and some simple firepower adjustment actions can be realized by controlling the stepper motors. There are some problems in these designs. For example, the cock valve adjustment mechanism needs to change the cock angle when adjusting the gas flow, adjust the flow area of the corresponding hole on the cock and the valve body, and realize the adjustment of gas flow and firepower. After the position is adjusted, the gas output The flow rate increases with the increase of external gas pressure, so the requirement for external gas input pressure is very high. Moreover, the adjustment range is narrow. Generally, the plug valve controlled by a stepping motor can only realize 5 or 6 firepower adjustment points, and there is no continuity between each point, and they are all set separately. Moreover, the cock valve needs to be replaced for different gas types, that is to say, the gas cock valve assembly needs to be replaced when changing the type of gas used, which increases the overall cost. The cock structure is also easy to get stuck, and the stepper motor belongs to the open-loop control method, so the structure of the stepper motor control cock valve is prone to missing steps and skipping steps, which will eventually lead to adjustment failure; the cock valve controlled by the stepper motor has a large volume , and only the left and right interface methods, the valve bodies of the left and right interfaces cannot be used in common with each other, and can only support cookers with two burners, and cannot be used for cookers with more than three burners.

detailed description

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1-3, the valve body assembly of the household gas stove in the embodiment of the present utility model includes a main pipeline 10, and a branch pipeline connected to the main pipeline 10, as shown in Figure 1, includes a first Road pipe 20 and second branch pipe 30. The inlet end of the main pipeline 10 is provided with a main pipeline solenoid valve 11 for controlling the on-off of the main pipeline 10 . At the position where each branch pipeline is connected to the main pipeline 10, a branch solenoid valve is provided to control the on-off of each branch. For example, the first branch pipeline 20 is provided with a first branch solenoid valve 21 , and the second branch pipeline 30 is provided with a second branch solenoid valve 31 .

Each branch is provided with a proportional valve, the first branch pipeline 20 is provided with a first proportional valve 22 , and the second branch pipeline 30 is provided with a second proportional valve 32 . The proportional valve is used to control the size of the air flow on the branch pipeline. And each branch has two outlets, the inner ring outlet corresponds to the outer ring mixing chamber, the other outer ring outlet corresponds to the inner ring mixing chamber, and the outlet corresponding to the outer ring mixing chamber is also equipped with an outer ring solenoid valve , used to control the on-off of the outer ring outlet. For example, the first branch pipe 20 is provided with a first outer ring outlet 23 and a first inner ring outlet 24 , and the first outer ring outlet 23 is provided with a first outer ring solenoid valve 25 . The second branch pipe 30 is provided with a second outer ring outlet 33 and a second inner ring outlet 34 , and the second outer ring outlet 33 is provided with a second outer ring solenoid valve 35 .
