Pipe is equipped with argon gas air vent；
The detachable blocking component of described second is equipped with exhaust passage, one end of the exhaust passage and the protection
Gas welding area is connected, and the other end is connected with exhaust area.
The utility model has the beneficial effects that：
The advantages of novel argon-filled protection device, is applicable in different tube diameters, and recycling is high, facilitates portable, reduces argon gas and protects
Area is protected, argon gas dosage is greatly reduced, argon filling area purity of argon is high, guarantees construction quality, will not be in pipe by tow cable
Pollute and block, it is ensured that in actual operation, stainless steel pipes argon filling gas shielded weldering welding quality, it is convenient and efficient simultaneously
And greatly guarantee the purity of argon gas.
