Description
Technical field
The present invention relates to welding gun technical field more particularly to a kind of magnetic controlled energy-saving welding gun structures.
Background technology
Welding gun is a kind of tool for gas welding, and for shape as rifle, there is nozzle in front end, sprays thermal-flame as heat source.By
Usually all it is intermittent in weld job, therefore the working condition of welding gun is generally also discontinuous operation, traditional welding gun is in itself
Included control valve controls gas, and process is：Work first beginning when, open the control valve of oxygen and combustion gas respectively,
It lights welding gun and generates flame；Secondly the required flame of work is adjusted using oxygen and gas control valve door；Again, work knot
Shu Shi closes fuel gas and oxygen valve door, fray-out of flame respectively.In the state of welding gun discontinuous operation, control valve is adjusted
Lag, both wastes gas, also wastes the working time, and combustion gas effusion also pollutes the environment.In order to which saving gas wastes, using tradition
Mechanical valve control oxygen and combustion gas, after long-term work, link rod part will gas leakage, not only wasted gas but also had security risk.
Invention content
The present invention is easy to cause gas leakage, waste combustion to solve the control valve control lag of welding gun in the prior art
The problem of gas, pollution environment, provide a kind of magnetic controlled energy-saving welding gun structure, oxygen and the control of combustion gas break-make are non-in this kind of welding gun
Often convenient, response quickly, greatly reduce oxygen, combustion gas waste, save gas energy, reduce gas pollution.Control gas
The permanent magnet that the spool of body break-make drives with it does not have the connection in mechanical structure, has prevented the leakage of gas from structure, more
What is added is safe and reliable.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of magnetic controlled energy-saving welding gun structure, including connecting seat, air jet pipe, one end and the connecting seat of the air jet pipe connect
