Embodiment Construction
[0022] Refer to Figure 1 to Figure 12 , a gas valve with an improved valve core structure, including a valve body 1 and a valve seat 2, a valve core is installed in a cavity formed by the valve body 1 and the valve seat 2, and the valve body 1 is provided with a valve for connecting gas The inlet channel 5 of source and the outlet channel 23 that is used to connect burner head, and nozzle 4 is installed at the end of outlet channel 23. The spool includes an outer spool 14 and an inner spool 12 installed in the outer spool 14, one end of the outer spool 14 is connected with a rotating shaft 3 inserted through the valve seat 2, the outer spool 14 and the rotating shaft 3 A spool spring 7 for resetting the rotating shaft is installed between them, and the end of the inner spool 12 near the rotating shaft is provided with an adjustment port 24, which can be a flat groove or a cross groove corresponding to a general-purpose screwdriver. A through hole 6 communicating with the adj...

The present invention discloses a gas valve with an improved valve core structure, which comprises a valve body, a valve seat, a hollow rotary shaft and a valve core; wherein, the valve core is composed of an external valve core and an internal valve core; the external valve core is provided with an intense-fire gas inlet and a small-fire gas inlet; the internal valve core is provided with two or more flow control holes respectively corresponding to different fuel gases. When the fuel gases need to be switched, a corresponding nozzle is replaced, the internal valve core is directly rotated by a tool such as a screwdriver via the throughhole of the rotary shaft, so that the corresponding flow control hole on the internal valve core is communicated with the small-fire gas inlet on the external valve core, as a result, the fuel gas flow for an intense fire can be restricted by the aperture of the nozzle, and the fuel gas flow for a small-fire can be controlled by the corresponding flow control hole on the internal valve core. The fuel gas valve, which has the advantages of convenient operation and safe and reliable use, is widely applicable to gas cookers, gas barbecue ovens, gas water heaters, etc., and the traditional fuel gas valve can be altered by replacing the valve core, the rotary shaft and the nozzle in order to achieve the purpose of the stable burning of two types of gas sources.
Description
technical field [0001] The invention relates to a gas valve, in particular to a gas valve with an improved valve core structure. Background technique [0002] Because different gases have different characteristics, their heat load, combustion potential, Wobbe number and other parameters are all different. When used on one valve, it is difficult to achieve the ideal combustion effect. Since the traditional valve can only be used for one gas source, if the gas source needs to be changed, the valve must be replaced again to achieve the purpose of stably burning another gas source on the same burner. However, such an operation will make manufacturers and users feel very inconvenient, and at the same time cause a great waste of resources. If the user replaces it by himself, there will be certain safety hazards, which will easily lead to catastrophic accidents. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a g...
