Problems solved by technology

Usually, the condition of use is to keep the fire burning for a period of time after the main fire is extinguished, and then turn off the fire when it is confirmed that the stove is not needed. At this time, it often happens that only the fire valve is turned off, and the gas valve of the main fire pipe is forgotten, resulting in gas leakage. ACCIDENT
There is also a device that links two gas valves by setting an electronic circuit, but its stability and reliability are poor

Embodiment 1

[0020] like figure 1 As shown, a mechanical safety valve includes a gas distribution valve 1 and a main fire valve 2. The gas distribution valve 1 includes a housing 11 and a valve core 12 arranged in the housing 11. The housing 11 is ten Glyph, including the connected gas inlet 111, first outlet 112, second outlet 113, the other end is closed, the second outlet 113 is connected to the main fire valve 2, the valve core 1 is cylindrical, and is arranged at the intersection of the housing 11 , the valve core 12 is also provided with a handle 13 protruding from the closed end of the housing 11;

[0021] like figure 2 , 3 As shown, an air groove 121 is arranged between the upper and lower bottom surfaces of the valve core 12. The air groove 121 is located on one side of the central axis 122 of the valve core 12, and the depth does not exceed the central axis 122. The upper bottom surface of the valve core 12 An air hole 123 communicating with the air groove 121 is provided, an...

Abstract

The invention relates to a mechanical safety valve. The mechanical safety valve comprises a fuel gas distribution valve and a main fire valve, wherein the fuel gas distribution valve comprises a shelland a valve element arranged in the shell, wherein the shell is in a cross shape and comprises a gas inlet, a first outlet and a second outlet which communicating with the shell, the other end of theshell is closed, and the second outlet is connected with a main fire valve; the valve element is cylindrical, the cross part of the shell is provided with a cylindrical cavity matched with the valveelement, and a rotating handle extending out of the closed end of the shell is further arranged on the valve element; and an air groove is formed between the upper bottom surface and the lower bottomsurface of the valve element, the air groove is located on one side of the central axis of the valve element, and the depth does not exceed the central axis; and an air hole communicating with the airgroove is formed in the upper bottom surface of the valve element, and the rotating handle is arranged on the lower bottom surface of the valve element. According to the valve, a pure mechanical structure is adopted, compared with an electronic control, the stability and reliability are higher, and the valve is safer.

Description

technical field [0001] The invention relates to a mechanical safety valve, in particular to a gas distribution valve. Background technique [0002] In a common commercial stove, it usually includes a main fire pipe and a kindling pipe. The main fire pipe is used to generate a large fire for cooking. waste. The conventional main fire pipe and the ignition pipe are connected to the gas source through a three-way pipe, and each is provided with an independent gas valve. Usually, the condition of use is to keep the fire burning for a period of time after the main fire is extinguished, and then turn off the fire when it is confirmed that the stove is not needed. At this time, it often happens that only the fire valve is turned off, and the gas valve of the main fire pipe is forgotten, resulting in gas leakage. ACCIDENT. There is also a device for linking two gas valves by setting an electronic circuit, but its stability and reliability are relatively poor. Contents of the in...
