Fuel gas mixing bag for producting energy saving lamp

Abstract

The invention belongs to the technical field of energy-saving light production equipment and mainly relates to a fuel gas mixing bag, which mainly comprises a valve body (5), a regulating valve and a gas mixing valve, wherein three independent main pipe cavities are formed in the valve (5), and are connected with an oxygen source, a compressed air source and a fuel gas source to form an oxygen main pipe, a compressed air main pipe and a fuel gas main pipe, which are independent; correspondingly, each of the oxygen main pipe, the compressed air main pipe, the fuel gas main pipe is provided with a row of regulating valves; each three regulating valves which are communicated with the three main pipes respectively form a group and are communicated with a corresponding gas mixing valve; and each gas mixing valve is connected with a fire using point by a mixed gas connector (6) and a pipe. In the invention, the independent valve structure simplifies overall arrangement and shortens the lengths of the main pipes; and the regulating valves arranged in a concentrated manner can perform concentrated control and realization of the mixing of gases in any ratio; and the fuel gas mixing bag has the characteristics of convenient operation and maintenance and convenient installation.

Description

Technical field [0001] The invention belongs to the technical field of energy-saving lamp production equipment, and mainly relates to a gas mixing bag used for the production of energy-saving lamps. Background technique [0002] At present, the flame adjustment method used in the production process of the energy-saving lamp tube is a separate control method, that is, the three gases used for each fire point are connected to the branch pipes from the three gas source main pipes, and each gas passes through the valve. After adjusting the gas output, it is sent to the burner through the gas mixing pipe. There are mainly the following problems when using this method: [0003] 1. When there are many fire points and a large amount of fire, in order to facilitate the welding of branch pipes, the main pipe with large diameter is often very long. [0004] 2. There will be multiple pipe circumferential welds corresponding to each fire point, and multiple threaded connections, resulting in ma...

AI Technical Summary

Problems solved by technology

[0003] 1. When there are many fire points and a large amount of fire, in order to facilitate the welding of branch pipes, the main pipe with large diameter is often very long

[0004] 2. Each fire point corresponds to multiple pipe circumferential welds and multiple threaded connections, resulting in many hidden failure points, high maintenance rate and inconvenient processing

[0005] 3. When other production factors such as air pressure fluctuations change, it is necessary to adjust the height and temperature of the flame, because the adjustment switches are scattered, which is not conducive to rapid adjustment

[0006] 4. The gas mixing effect of this method is not good, which affects the flame energy efficiency and shape stability, and easily forms turbulent flow and eddy current dead angle, resulting in unstable product quality and affecting production efficiency

[0007] 5. The overall layout is messy and inconvenient to operate

[0008] 6. When checking the gas circuit of the machine, the whole machine must be completely shut down before proceeding.

[0009] 7. It is easy to produce toxic and harmful flammable gases
