Description

Technical Field

[0002] As a key control component in gas equipment, the rationality of the gas circuit structure design of the gas valve body directly affects the stability of gas supply, ease of installation, and overall equipment efficiency. Existing gas valve bodies typically employ a multi-independent gas circuit design, with gas distribution often requiring complex internal channels or external connectors. This results in a complex internal gas channel structure, high manufacturing difficulty, and susceptibility to gas leakage due to assembly errors. Furthermore, the gas pipe layout of traditional gas valve bodies is relatively dispersed, with inconsistent horizontal levels among the pipes. This not only occupies significant installation space but also increases the complexity of pipe connections, hindering the compact design of the entire unit. Utility Model Content

[0015] See appendix Figure 1-2This application provides a gas circuit structure for a gas valve body, which includes a valve body 1, a first gas pipe 2, and a second gas pipe 3. The valve body 1 is provided with a valve core cavity 4 and an air inlet 5, and the air inlet 5 is connected to the valve core cavity 4. The front side of the valve body 1 is provided with a front seat 6 protruding forward. The first gas pipe 2 is provided on the front seat 6. A horizontal pipe 7 is provided on the right side of the front seat 6. The second gas pipe 3 is provided on the horizontal pipe 7 and is parallel to the first gas pipe 2. The horizontal height of the second gas pipe 3 is the same as the horizontal height of the first gas pipe 2. The front seat 6 is provided with a first air passage and a second air passage. The first air passage connects the first gas pipe 2 and the valve core cavity 4. The second air passage connects the horizontal pipe 7 and the valve core cavity 4. The second gas pipe 3 is connected to the horizontal pipe 7. This solution optimizes the air path layout by arranging the first air pipe 2 and the second air pipe 3 in parallel and at the same horizontal height, and integrating them on the front seat 6 and the horizontal pipe 7 on the front side of the valve body 1. This results in a compact structure and reduces the space occupied during installation. In addition, the front seat 6 is equipped with a first air passage and a second air passage, which connect the first air pipe 2, the second air pipe 3 and the valve core cavity 4 respectively. This simplifies the air path structure, reduces the processing difficulty, and improves the stability and reliability of gas distribution.

[0016] The valve core cavity 4 has a first air hole 8 and a second air hole 9 on the cavity wall corresponding to the position of the front seat 6. The first air hole 8 and the second air hole 9 are distributed vertically. The first air hole 8 is connected to the first air passage, and the second air hole 9 is connected to the second air passage. This structure makes the air path flow clear, reduces air path crossing and interference, and the vertically distributed air hole structure is conducive to gas stratification control, improving the adjustment accuracy and response speed of the valve body.

An air nozzle 12 is located at the front end of the ignition gas pipe 11. A third gas hole 13 connecting to the third gas pipe 10 is opened on the cavity wall of the valve core cavity 4, realizing independent control of the ignition gas path and improving ignition safety and reliability. Specifically, the port of the third gas pipe 10 has a threaded structure, and the ignition gas pipe 11 has a threaded connector that connects to the threaded structure. The threaded connector has a non-circular fixing part 14, which facilitates the installation and disassembly of the ignition gas pipe and improves maintenance convenience. The non-circular fixing part 14 can be pentagonal or hexagonal to facilitate installation with a wrench.

[0020] The opening of the valve core cavity 4 is located at the top of the valve body 1. A first recessed recess 15 is provided at the opening of the valve core cavity 4. The air inlet 5 is located at the rear side of the valve body 1. A second recessed recess 16 is provided at the air inlet 5. The first recessed recess 15 and the second recessed recess 16 can be used to fix the sealing ring to improve the sealing performance.

[0021] The valve body 1 has a first threaded hole 17 and a second threaded hole 18 at the top and air inlet 5, respectively. The first threaded hole 17 and the second threaded hole 18 facilitate the fixed connection between the valve body and external equipment, thereby improving installation stability and reliability.
