Description

Technical Field

[0001] The utility model relates to the technical field of kitchen stoves, in particular to a double - type intake valve for commercial stoves. Background Art

[0002] Commercial stoves using liquid fuel need to deliver air to the burner head through an air pump and can adjust the fire size of the burner head by changing the intake air volume. Currently, generally two groups of regulating valves are set at the intake end of the air pump to control the intake air volume during high - fire and low - fire respectively. Referring to Figure 1 , a customized three - way joint 200 is installed at the intake end of the air pump 100. One interface of the three - way joint 200 is connected with a high - fire control valve 300 through a pipeline. The high - fire control valve is generally installed at the front side of the stove top for easy operation and adjustment by the chef; the other interface is directly equipped with a low - fire control valve 400. When in use, the low - fire control valve is always open. When the high - fire control valve is opened, the burner head gives out high - fire. When the high - fire control valve is closed, the burner head gives out low - fire, and the size of the low - fire can be controlled by adjusting the low - fire control valve.

[0003] However, this kind of intake valve has some drawbacks in actual application. First, there are many accessories, which increases the cost on one hand and makes the installation cumbersome on the other hand. Second, the low - fire control valve is generally located at the back side of the stove top, making it extremely inconvenient to adjust the low - fire. In addition, the current low - fire control valve has low precision. When using liquid fuels with different consistencies, it is difficult to accurately control the fire size during adjustment, and it has strict requirements on the consistency of the liquid fuel, with low applicability.

[0020] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further specifically described below through embodiments.

[0021] Embodiment: A double - type air intake valve for a commercial stove, as Figure 2-6 shown, includes a valve body 1. The valve body 1 is provided with an air inlet 2 and an air outlet 3. The air inlet 2 is used for air intake and can be externally connected to a silencing and filtering device for air intake. The air outlet 3 is connected to the air inlet end of an air pump through a pipeline.

[0022] Two air passages are arranged in the valve body 1, namely a main air passage 4 and an auxiliary air passage 5. The main air passage 4 is used for adjusting the air intake volume of the large fire, and the auxiliary air passage 5 is used for adjusting the air intake volume of the small fire.

[0023] In the above structure, a valve core 6 is arranged near the air outlet of the valve body 1. The middle of the valve core 6 is a through channel, which is communicated with the main air duct 4. An annular groove 61 is formed on the side surface of the valve core 6. When the valve core 6 is installed in the valve body 1, the space surrounded by the annular groove 61 and the valve body 1 is communicated with the auxiliary air duct 5, and a plurality of ventilation holes 62 are uniformly arranged on the bottom surface of the annular groove 61, so that the auxiliary air duct 5 is communicated with the channel in the middle of the valve core 6, so that both the main air duct 4 and the auxiliary air duct 5 can communicate the air inlet 2 and the air outlet 3.

[0024] In this embodiment, a regulating valve 7 is arranged on the main air duct 4. The regulating valve 7 is a ball valve, which includes a valve ball 71, a valve rod 72 and a regulating handle 73. Specifically, the valve core 6 is vertically communicated with the main air duct 7. The valve ball 71 is located at the inflection point. The channel in the valve ball 71 is L-shaped. The communication or blocking between the valve core 6 and the main air duct 4 can be realized by rotating the valve ball 71; the valve rod 72 is rotatably arranged in the valve body 1, and the bottom end thereof is in a "one" shape, and a matching "one" shaped groove is also correspondingly arranged on the surface of the valve ball 71, so that the valve ball 71 can be driven to rotate when the valve rod 72 rotates; the outer end of the valve rod 72 is connected with the regulating handle 73. In addition, a limiting groove 74 is arranged on the valve rod 72, and a limiting column 75 matching with it is arranged in the valve body 1 to limit the maximum rotation angle of the valve rod 72.
