AI Technical Summary
The minimum flame setting of the existing gas valve cannot be used for both liquefied petroleum gas (LPG) and natural gas simultaneously, which can easily lead to flameout when the gas supply is mismatched.
A gas valve structure for stoves was designed. By adjusting the gas flow rate of the side gas passage through the flame adjustment screw on the front side of the valve body, and by using a sealing ring and a solenoid valve, flexible adaptation to the gas source can be achieved, ensuring the stability of the gas flow rate.
This solves the compatibility issue of gas valves with different gas sources, avoids flameout, and reduces post-processing costs.

Abstract
Description
[Technical Field]
[0001] This utility model relates to a gas valve structure for a stove. [Background Technology]
[0002] A gas valve is a valve body used to control the on / off state and volume of gas. Currently, most gas valves on the market have a minimum flame setting. However, since there are two types of gas sources on the market, namely liquefied petroleum gas (LPG) and natural gas, the minimum flame setting of the gas valve at the factory cannot be used for both LPG and natural gas simultaneously. For example, if the minimum flame setting of the gas valve is for LPG, but the user is using natural gas, the flame may go out if the user adjusts the flame to the minimum. This is because the densities of the two gas sources are different. Solving this problem requires modifying the gas circuit structure, which is very troublesome.
[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]
[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a gas valve structure for stoves, which can be externally adjusted to solve the compatibility problem between natural gas and liquefied petroleum gas.
[0005] To achieve the above objectives, this utility model provides a gas valve structure for a stove, comprising a valve body having a first gas pipe and a second gas pipe, a valve core cavity being provided within the valve body, the first gas pipe and the second gas pipe being connected to the valve core cavity, a side gas passage being provided within the valve body, the side gas passage being connected to the valve core cavity and the first gas pipe respectively, an installation channel penetrating to the side gas passage being provided on the front side of the valve body, an adjusting screw being screwed onto the installation channel, the end of the adjusting screw being used to block the side gas passage and adjust the gas flow rate of the side gas passage, the adjusting end of the adjusting screw being exposed outside the installation channel.
[0006] In one or more embodiments, the mounting channel is provided with threaded and non-threaded sections from the outside to the inside, and a sealing ring is fitted on the surface of the ignition screw, which cooperates with the non-threaded section to seal.
[0007] In one or more embodiments, the surface of the ignition screw is provided with a positioning groove, and the sealing ring is fitted onto the positioning groove.
[0008] In one or more embodiments, the adjusting end of the ignition screw has one of the following: slotted groove, cross groove, hexagonal groove, and triangular groove.
[0009] In one or more embodiments, the bottom of the valve body is provided with a mounting cavity and an air inlet pipe, the air inlet pipe is connected to the mounting cavity, the valve body is provided with a solenoid valve at the connection between the air inlet pipe and the mounting cavity, the mounting cavity is provided with a transmission part for opening the solenoid valve, the mounting cavity is located below the valve core cavity and is connected to the valve core cavity, and the transmission part is pushed by a valve rod connected to the valve core cavity.
[0010] In one or more embodiments, the bottom of the valve body is provided with a sealing cover for opening the mounting cavity.
[0011] Compared with the prior art, the advantages of this utility model are: users can adjust the gas flow rate of the side gas passage by adjusting the ignition screw on the front side of the valve body, so as to solve the problem of flameout caused by insufficient gas supply due to the low density of natural gas; this structure can facilitate the adjustment of the gas supply of the gas valve and reduce the subsequent processing costs.

Detailed Implementation Methods
[0015] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0016] Please refer to Figure 1-2This application discloses a gas valve structure for a stove, comprising a valve body 1 having a first gas pipe 2 and a second gas pipe 3. A valve core cavity is provided within the valve body, and both the first and second gas pipes communicate with the valve core cavity. A side gas passage 4 is provided within the valve body 1, connecting the valve core cavity and the first gas pipe 2. An installation channel 5 extending through the side gas passage is provided on the front side of the valve body. An adjusting screw 6 is screwed onto the installation channel. The end of the adjusting screw is used to block the side gas passage and adjust the gas flow rate of the side gas passage. The adjusting end 61 of the adjusting screw 6 is exposed. Specifically, when the gas valve is manufactured for LPG, but the user's gas source is natural gas, adjusting the ignition control screw increases the gas flow in the side gas channel. This ensures sufficient natural gas output to maintain the minimum flame setting, preventing flameout due to insufficient gas supply. Conversely, if the gas valve is manufactured for natural gas, adjusting the ignition control screw reduces the gas flow in the side gas channel, preventing a large flame even at minimum flame setting. This resolves the gas valve's compatibility issue with the gas source.
[0017] The installation channel 5 has a threaded section 7 and a non-threaded section 8 from the outside to the inside. A sealing ring 9 is fitted on the surface of the ignition screw. The sealing ring and the non-threaded section 8 cooperate to seal. The threaded connection itself is a connection method with good sealing performance. With the addition of the sealing ring for further sealing, the air leakage problem can be completely solved.
[0018] The surface of the ignition screw 6 is provided with a positioning groove, and the sealing ring is fitted onto the positioning groove. The positioning groove can better fix the sealing ring and prevent the sealing ring from shifting. At the same time, when the sealing ring ages, it can be replaced by unscrewing the ignition screw.
[0019] To make it easier for users to operate the ignition screw, the adjusting end 61 of the ignition screw has one of the following slots: slotted, cross-shaped, hexagonal, or triangular. These slot types are all relatively common, and most users have screwdrivers with these slot types at home.
[0020] See appendix Figure 3 The bottom of the valve body 1 is provided with an installation cavity 10 and an air inlet pipe 11. The air inlet pipe is connected to the installation cavity. The valve body is provided with a solenoid valve 12 at the connection between the air inlet pipe and the installation cavity. The installation cavity is provided with a transmission part 13 for opening the solenoid valve. The installation cavity 10 is located below the valve core cavity and is connected to the valve core cavity. The transmission part 13 is pushed by a valve rod 14 connected to the valve core cavity. When the user operates the valve rod, the valve rod presses down on the transmission part, causing the other end of the transmission part to open the solenoid valve, thereby connecting the gas supply to the air inlet pipe, the installation cavity and the valve core cavity.
[0021] The bottom of the valve body 1 is provided with a sealing cover plate 15 for opening the installation cavity. The sealing cover plate is fixed to the valve body with screws, so that it can be easily repaired and replaced when the transmission part is damaged.
[0022] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
