Problems solved by technology

If NG gas is used on the LPG stove, the fire is very small and cannot be used for heating; it may not even burn, causing gas leakage and deflagration accidents
If LPG gas is used on the NG stove, it will generate a large flame, and there is a danger of igniting the surrounding items; at the same time, it will also produce incomplete gas, generate too much CO, and cause CO poisoning

Embodiment 1

[0033] Please refer to figure 1 , Embodiment 1 of the present invention is: a column-type gas identification device, including a column-type housing 1, the upper end of the column-type housing 1 is a gas inlet 2, and the two sides are respectively provided with a low-pressure gas outlet 31 and a high-pressure gas outlet 32, wherein the position of the high-pressure gas outlet 32 ​​is higher than that of the low-pressure gas outlet 31. Below the cavity inside the housing is a sealed cavity 4, and the sealed cavity 4 is filled with inert gas. Above the sealing chamber 4 is the first sealing piston 5. The first sealing piston 5 is also columnar, which just fits the inner wall of the housing cavity and can move up and down along the inner wall of the cavity to ensure airtightness and at the same time the friction force is very small , can be ignored. A groove 6 is provided on the side of the first sealing piston, and a gas passage 7 is provided from the upper end of the first se...

Embodiment 2

[0071] Please refer to Figure 5 The difference between the second embodiment of the present invention and the first embodiment is that a spring is used instead of an inert gas. Such as Figure 5 As shown, a spring 12 is provided in the sealing chamber 4. In order to ensure the normal deformation of the spring, it is preferable that one end of the spring 12 is connected to the first sealing piston. Of course, as long as the spring size is suitable and can deform normally, it may not be connected to the first sealing piston. , but only deformed by the piston pressure. Further, in order to ensure that the spring deforms in the vertical direction, a spring guide shaft 13 with one end connected to the first sealing piston can also be provided in the sealing chamber 4, and the spring 12 is arranged around the spring guide shaft. The other end of the spring guide shaft passes through the housing from the bottom of the sealing cavity. When the first sealing piston is compressed and...

Embodiment 3

[0082] Please refer to Figure 8 The difference between the third embodiment of the present invention and the first and second embodiments is that the deformation mode of the inert gas and the spring is changed to a hydraulic structure. In this embodiment, the casing 1 is a U-shaped column structure, one end of the U-shaped column is the gas inlet 2, the other end is the gas outlet 16, and the liquid sealing chamber 14 is located below the first sealing piston 5, and the liquid The sealing chamber 14 is also U-shaped, one end of which is connected to the first sealing piston 5 , and the other end is connected to the second sealing piston 15 . Affected by the gas pressure above the first sealing piston 5 , the first sealing piston 5 can be pushed down, thereby pushing the liquid in the liquid sealing chamber 14 and the second sealing piston 15 to move accordingly. For the rationality of the gas outlet, the high-pressure gas outlet and the low-pressure gas outlet can be arrange...

Abstract

The invention discloses a column-type gas recognition device which comprises a columnar shell, wherein the shell is composed of a gas inlet formed in the upper end of the shell, a low-pressure gas outlet and a high-pressure gas outlet; the low-pressure gas outlet and the high-pressure gas outlet are formed in the two sides of the shell respectively; the low-pressure gas outlet is lower than the high-pressure gas outlet; a sealing cavity is formed below a cavity in the shell; a first sealing piston is arranged above the sealing cavity; a circle of groove is formed in the side surface of the first sealing piston; and a low-pressure gas channel is formed from the top end of the first sealing piston to the groove. According to the column-type gas recognition device disclosed by the invention, the piston moves up and down by utilizing different pressures of different gases, so that different gases are regulated to be discharged from different outlets and are automatically recognized.

Description

technical field [0001] The invention relates to the field of life, in particular to a column type gas identification device. Background technique [0002] Gas is an indispensable source of energy in people's daily life, and gas stoves and gas water heaters have been widely used household appliances. At present, the commonly used gas in my country includes NG (Natural Gas) natural gas and LPG (Liquefied Petroleum Gas) liquefied petroleum gas. Due to the different working methods of different gases, most household appliances can only use one of them. If NG gas is used on the LPG stove, the fire is very small and cannot be used for heating; it may not even burn, causing gas leakage and deflagration accidents. If LPG gas is used on the NG stove, it will generate a large flame, and there is a danger of igniting the surrounding objects; at the same time, it will also produce incomplete gas, produce too much CO, and cause CO poisoning. Therefore, in order to be applicable to natu...
