Problems solved by technology

However, in the current dual gas source gas system, when different gases are connected, the system will not switch to the correct pressure reducing valve, safety ignition device and nozzle, and manual replacement is required, which is inconvenient to use, and the user will The liquefied petroleum gas is connected to the natural gas inlet by mistake, because the calorific value of liquefied petroleum gas is higher than that of natural gas, once the connection is wrong, when the main flame is turned on, the flame will become very large, which is a safety hazard, so this device is added

specific Embodiment approach

[0033] Such as figure 1 As shown, a gas valve includes a valve body, the valve body is provided with a high calorific value gas channel and a low calorific value gas channel; the valve body is provided with a safety ignition device air inlet 405 and respectively connected with the safety ignition A low calorific value gas safety ignition device gas outlet 403 and a high calorific value gas safety ignition device gas outlet 404 connected to the air inlet of the device also include a low calorific value gas channel that can be cut off after the low calorific value gas channel is connected to the high calorific value gas, And the safety ignition device cut-off valve 406 that connects the low-calorific-value gas channel after the low-calorific-value gas channel is connected.

[0034] Such as Figure 2 to Figure 7 As shown, the present invention also includes a control chamber 4602, the right side of the film is arranged in the control chamber 4602, and the sealing rod communicate...

Abstract

The invention discloses a valve body. The valve body is provided with a high-heat gas passage and a low-heat gas passage inside. The valve body is provided with a safety ignition device gas inlet, a low-heat gas safety ignition device gas outlet, a high-heat gas safety ignition device gas outlet and a safety ignition device shut-off valve. The low-heat gas safety ignition device gas outlet and the high-heat gas safety ignition device gas outlet are communicated with the safety ignition device gas inlet. When high-heat gas is fed into the low-heat gas passage, the safety ignition device shut-off valve can shut off the low-heat gas passage. When low-heat gas is fed into the low-heat gas passage, the safety ignition device shut-off valve can allow for communication of the low-heat gas passage. When different gases are fed, a system can switch to corresponding reducing valves, safety ignition devices and nozzles. By the safety ignition device shut-off valve, when a user mistakenly feed liquefied gas into a natural gas inlet, the low-heat gas passage is shut off immediately due to the fact that pressure of the liquefied gas is higher than natural gas, and accordingly potential safety hazard is avoided.

Description

technical field [0001] The invention provides a pressure reducing valve, more specifically a gas valve. Background technique [0002] In a general gas system, the gas pressure is different, the pressure reducing valve is different, the corresponding safety ignition device will be different, and the gas nozzle will be different. However, in the current dual gas source gas system, when different gases are connected, the system will not switch to the correct pressure reducing valve, safety ignition device and nozzle, and manual replacement is required, which is inconvenient to use, and the user will The liquefied petroleum gas was wrongly connected to the natural gas inlet, because the calorific value of liquefied petroleum gas is higher than that of natural gas, once the connection is wrong, when the main flame is turned on, the flame will become very large, which is a safety hazard, so this device is added. Contents of the invention [0003] The object of the present inven...
