Problems solved by technology

Since the traditional valve can only be used for one gas source, if the gas source is changed, the valve must be replaced, or the internal parts of the valve must be replaced to achieve the stability of another gas source on the same burner The purpose of burning, 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 a certain risk, which will easily lead to catastrophic accidents.

Embodiment Construction

[0017] Referring to Figure 1, figure 2 , a gas valve for two gases shared by the present invention, comprising a valve body 1, a nozzle 2 is installed on the valve body 1, a valve core 3 is installed in the valve body 1, and a valve seat 6 is installed at one end of the valve body 1, The valve seat 6 confines the valve core 3 in the valve body 1 . A rotating shaft 4 is connected to the valve core 3, and the rotating shaft 4 is connected to the valve core through a positioning pin 7. A knob 5 is installed on one end of the rotating shaft 4. As shown in the figure, the valve body 1 is provided with an air source inlet channel 11 and b gas source intake passage 12.

[0018] refer to image 3 , The valve core 3 is provided with an air source channel 31 , wherein one end of the air source channel 31 is sealed by a sealing screw 8 . A gas source chamber 311 and a b gas source chamber 312 are arranged in the gas source channel 31 , a nozzle hole 32 is arranged between the two cham...

Abstract

The invention discloses a two-gas sharing gas valve, comprising a valve body with a built-in valve core, characterized in that the valve body is provided with a, b air supply intake passage, the valve core is provided with an gas supply passage, two chambers are arranged in the gas supply passage, a spray nozzle aperture is provided between the two chambers. The a, b gas supply inlets are arranged on two sides of the valve core, wherein the a gas supply inlet communicates with one of the chambers, when using the a gas supply, it communicates with the a gas supply intake passage. The b gas supply inlet communicates with the other chamber, when using the b gas supply, it communicates with the b gas supply intake passage. No service parts will be replaced when replacing gas supplies by employing structure of the invention, which is easy and safe to use. Meanwhile, unnecessary waste is avoided, thereby decreasing occurence ratio of failure greatly.

Description

technical field [0001] The invention relates to a gas valve, in particular to a gas valve which can be shared by two kinds of gas sources. Background technique [0002] Because different gases have different characteristics, their parameters such as heat load, combustion potential, Wobbe number, etc. are all different, so different valves must be used for different gases, so that the gas can be fully combusted and the maximum utilization of the gas can be achieved. thermal energy. Since the traditional valve can only be used for one gas source, if the gas source is changed, the valve must be replaced, or the internal parts of the valve must be replaced to achieve the stability of another gas source on the same burner The purpose of burning, 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 a certain risk, which will easily lead to catas...
