Description

Technical Field

[0001] The utility model relates to the technical field of valve tools, in particular to a valve body structure and a gas valve. Background Art

[0002] The valve body structure of a gas valve generally includes a valve body and an air inlet pipe and an air outlet pipe connected to the side wall of the valve body. The valve body has a valve cavity for installing a valve core. The air inlet pipe has an air inlet channel connected to the valve cavity, and the air outlet pipe has an air outlet channel connected to the valve cavity. The valve core can control the opening and closing of the air inlet channel and / or the air outlet channel. Among them, the air outlet pipe is generally directly arranged on the side wall of the valve body and extends outward in a direction away from the valve body. However, in a specific installation environment, due to the internal layout and size of the stove, it is easy for the burner to be unsuitable for the above-mentioned gas valve body. During installation, the gas valve and the burner need to be installed in a staggered manner. For example, it is easy to arrange the burner air inlet pipe parallel to the axis of the valve cavity, or to arrange the burner air inlet pipe parallel to the valve body structure air outlet pipe and staggered. In this case, refer to Figure 1 and Figure 2 To facilitate the delivery of gas from the gas valve's outlet passage to the burner, an adapter 600 is typically installed at the outlet end of the gas outlet pipe. This adapter 600 redirects the gas flow and guides it to the burner's air inlet. However, this structure requires not only the valve body but also the adapter 600 to be installed when using the gas valve, making installation more cumbersome. Furthermore, over extended use, the airtightness between the adapter 600 and the outlet pipe can easily deteriorate, posing a safety hazard. Utility Model Content

[0042] Reference Figures 3 to 7One embodiment of the present invention provides a valve body structure, comprising a valve body 100, an air inlet pipe 200, an air outlet pipe 300, and a first auxiliary air outlet pipe 310. The valve body 100 has a valve cavity 110. The air inlet pipe 200 is connected to the side wall of the valve body 100 and has an air inlet channel 210 communicating with the valve cavity 110. The air outlet pipe 300 is connected to the side wall of the valve body 100 and extends outward in a direction away from the valve body 100. The air outlet pipe 300 has an air outlet channel 301 communicating with the valve cavity 110. The first auxiliary air outlet pipe 310 is connected to the end of the air outlet pipe 300 away from the valve body 100 and has a first auxiliary air outlet channel 311 communicating with the air outlet channel 301. The axis of the first auxiliary air outlet channel 311 forms an angle a with the axis of the air outlet channel 301, where 0°<a<180°. The valve body 100 , the air inlet pipe 200 , the air outlet pipe 300 and the first auxiliary air outlet pipe 310 are an integrated structure.

[0043] By adopting the valve body structure of the embodiment of the present invention, a first auxiliary air outlet pipe 310 is arranged at the end of the air outlet pipe 300 away from the valve main body 100, and the air outlet pipe 300 is provided with an air outlet channel 301 connected to the valve cavity 110, and the first auxiliary air outlet pipe 310 is provided with a first auxiliary air outlet channel 311 connected to the first valve cavity 110, and the axis of the air outlet channel 301 and the axis of the first auxiliary air outlet channel 311 have an angle a, 0°<a<180°, thereby enabling the first auxiliary air outlet channel 311 to change the flow direction of the gas in the air outlet channel 301. During use, the valve body structure of the embodiment of the present invention allows the valve body 100 to be installed on one side of the burner, with the first auxiliary gas outlet channel 311 facing the burner. As a result, the gas in the gas outlet channel 301 can flow into the first auxiliary gas outlet channel 311, which then guides the gas toward the burner. Therefore, there is no need to install an adapter 600 to change the flow direction of the gas in the gas outlet channel 301. The gas can be bent and delivered to the burner during use. Furthermore, because the valve body 100, the air inlet pipe 200, the air outlet pipe 300, and the auxiliary air outlet pipe 300 are an integrated structure, not only is the gas valve more convenient to install, but it also avoids airtightness issues between the adapter 600 and the air outlet pipe 300, thereby improving the airtightness of the gas valve.

[0044] It can be understood that there is an angle a between the axis of the above-mentioned first auxiliary gas outlet channel 311 and the axis of the gas outlet channel 301, 0°<a<180°. Specifically, the angle a between the axis of the first auxiliary gas outlet channel 311 and the axis of the gas outlet channel 301 can be 90°, or 30°, 45°, 60°, etc. The present invention does not make a specific limitation on this, and it only needs to be 0°<a<180°. In this way, the first auxiliary gas outlet channel 311 can change the flow direction of the gas in the gas outlet channel 301.

[0045] It can be understood that the above-mentioned valve body 100, air inlet pipe 200, air outlet pipe 300 and first auxiliary air outlet pipe 310 are an integrated structure. Specifically, the valve body 100, air inlet pipe 200, air outlet pipe 300 and first auxiliary air outlet pipe 310 can be an integrated molded structure, for example, by mold casting. In addition, the valve body 100, air inlet pipe 200, air outlet pipe 300 and first auxiliary air outlet pipe 310 can also be formed into an integrated structure by welding or other secondary molding methods, and the present invention does not make specific limitations on this.

[0046] It can be understood that in order for the valve body structure to be suitable for use in an environment where the burner has an ejector pipe, a nozzle 500 connected to the first auxiliary gas outlet channel 311 can be installed at the end of the first auxiliary gas outlet pipe 310 away from the gas outlet pipe 300, and the gas in the first auxiliary gas outlet pipe 310 is directly sprayed into the ejector pipe of the burner through the nozzle 500.

[0047] Reference Figures 3 to 7 In some embodiments, the axial direction of the first auxiliary air outlet channel 311 is arranged parallel to the axial direction of the valve cavity 110 .

[0048] By adopting the above structure, the axis of the first auxiliary gas outlet channel 311 is arranged parallel to the axis of the valve cavity 110, so that the valve body structure can be suitable for the use environment where the burner air inlet pipe and the valve cavity 110 are arranged parallel to each other. At this time, the first auxiliary gas outlet channel 311 can change the flow direction of the gas in the gas outlet channel 301, and guide the gas in the gas outlet channel 301 to turn and flow to the burner in a direction parallel to the axis of the valve cavity 110. Therefore, there is no need to additionally install the adapter 600 for changing the flow direction of the gas in the gas outlet channel 301, and the gas can be bent and transported to the burner during use. This not only makes the installation of the gas valve more convenient, but also avoids the airtightness problem between the adapter 600 and the gas outlet pipe 300, thereby improving the airtightness of the gas valve.

[0049] Reference Figures 3 to 7In some embodiments, the side wall of the valve body 100 is further provided with an installation port 120 for installing the valve stem assembly 140. The installation port 120 is connected to the valve cavity 110 and is coaxially arranged with the valve cavity 110. The first auxiliary air outlet pipe 310 is connected to the air outlet pipe 300 and extends in a direction away from the installation port 120.

[0050] By adopting the above structure, the valve core 130 is installed in the valve cavity 110 during use, and the valve stem assembly 140 for controlling the operation of the valve core 130 is installed at the installation port 120. By connecting the first auxiliary air outlet pipe 310 to the air outlet pipe 300 and extending it in a direction away from the installation port 120, the first auxiliary air outlet channel 311 can guide the gas in the air outlet channel 301 to turn and flow toward the burner. As a result, when in use, the valve stem assembly 140 is located on the side of the valve body away from the burner, thereby avoiding interference between the burner and the valve stem assembly 140, making it convenient for the user to operate the valve stem assembly 140.

[0051] Reference Figures 8 to 12 In some embodiments, the valve body structure further includes a second auxiliary air outlet pipe 320, which is integrally connected to the end of the first auxiliary air outlet pipe 310 away from the air outlet pipe 300. The second auxiliary air outlet pipe 320 has a second auxiliary air outlet channel 321 connected to the first auxiliary air outlet channel 311, and an angle b is formed between the axis of the second auxiliary air outlet channel 321 and the axis of the first auxiliary air outlet channel 311, where b=90°.

[0052] In the above structure, by providing a second auxiliary gas outlet pipe 320, the second auxiliary gas outlet pipe 320 is integrally connected to the end of the first auxiliary gas outlet pipe 310 away from the gas outlet pipe 300, and the axis of the second auxiliary gas outlet channel 321 and the axis of the first auxiliary gas outlet channel 311 have an angle b, b = 90°, so that when in use, the valve body 100 can be installed on one side of the burner, and the second auxiliary gas outlet channel 321 can be directed towards the burner, thereby, the second auxiliary gas outlet channel 321 can change the flow direction of the gas in the first auxiliary gas outlet channel 311, that is, through The second auxiliary gas outlet channel 321 can change the flow direction of the gas in the gas outlet channel 301 again, guiding the gas in the gas outlet channel 301 to turn again and flow toward the burner, so that the valve body structure can be suitable for more complex installation environments, and there is no need to additionally install an adapter 600 for changing the flow direction of the gas in the gas outlet channel 301. The gas can be bent and transported to the burner during use, which not only makes the installation of the gas valve more convenient, but also avoids the airtightness problem between the adapter 600 and the gas outlet pipe 300, thereby improving the airtightness of the gas valve.

[0053] It is understandable that there is an angle b between the axis of the second auxiliary air outlet channel 321 and the axis of the first auxiliary air outlet channel 311, b = 90 degrees, which is only for Figures 8 to 12 As an exemplary illustration, the angle b between the axis of the second auxiliary gas outlet channel 321 and the axis of the first auxiliary gas outlet channel 311 can be 90°, 30°, 45°, 60°, etc., and the present invention does not make any specific limitation on this. As long as 0°<b<180°, the second auxiliary gas outlet channel 321 can change the flow direction of the gas in the first auxiliary gas outlet channel 311.

[0054] It can be understood that the above-mentioned second auxiliary air outlet pipe 320 is integrally connected to the first auxiliary air outlet pipe 310. Specifically, the second auxiliary air outlet pipe 320 and the first auxiliary air outlet pipe 310 can be an integrally formed structure, for example, by mold casting. In addition, the second auxiliary air outlet pipe 320 and the first auxiliary air outlet pipe 310 can also be formed into an integral structure by welding or other secondary molding methods. The present invention does not make specific limitations on this.

[0055] It can be understood that in order for the valve body structure to be suitable for use in an environment where the burner has an ejector pipe, a nozzle 500 connected to the second auxiliary gas outlet channel 321 can be installed at the end of the second auxiliary gas outlet pipe 320 away from the first auxiliary gas outlet pipe 310, and the gas in the second auxiliary gas outlet pipe 320 is directly sprayed into the ejector pipe of the burner through the nozzle 500.

[0056] Reference Figures 7 to 12 In some embodiments, the axis of the second auxiliary air outlet channel 321 is arranged parallel to the axis of the air outlet channel 301 .

[0057] By adopting the above structure, the axis of the second auxiliary gas outlet channel 321 is arranged parallel to the axis of the gas outlet channel 301, so that the valve body structure can be suitable for the use environment where the burner head air inlet pipe 200 and the gas outlet pipe 300 of the valve body structure are parallel and staggered. At this time, the first auxiliary gas outlet channel 311 can change the flow direction of the gas in the gas outlet channel 301, guiding the gas in the gas outlet channel 301 to turn and flow toward the first auxiliary gas outlet channel 311, and the second auxiliary gas outlet channel 321 can guide the gas in the first auxiliary gas outlet channel 311 to turn again and flow in a direction parallel to the axis of the first gas outlet channel 301 to the burner head. Therefore, there is no need to additionally install the adapter 600 for changing the flow direction of the gas in the gas outlet channel 301, and the gas can be bent and transported to the burner head during use. This not only makes the installation of the gas valve more convenient, but also avoids the airtightness problem between the adapter 600 and the gas outlet pipe 300, thereby improving the airtightness of the gas valve.

The valve body structure further includes a second auxiliary gas outlet pipe 320, and the axis of the second auxiliary gas outlet channel 321 forms an angle b with respect to the axis of the first auxiliary gas outlet channel 311, b=90°. At this time, the gas outlet channel 301 can guide the gas in the valve cavity 110 to flow outward, and the first auxiliary gas outlet channel 311 can change the flow direction of the gas in the gas outlet channel 301, guiding the gas outlet channel 301 to flow outward.
