Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, a kind of automotive muffler air-tightness detection device, including plug A1, air gauge 2, plug B3, air source
4, the air gauge 2 is connect with plug A1, and the plug A1 and plug B3 are connect respectively by valve with air source 4, the plug
A1 and plug B3 is made of outer tube 5, inner tube 6, air bag 7, and the outer tube 5 is sleeved on outside inner tube 6, and 5 both ends of outer tube seal, and
It is connect with inner tube 6, the air bag 7 is sleeved on outside outer tube 5, and 7 both ends of air bag are fixed on by hose clamp on outer tube 5, to automobile
When silencer carries out air-leakage test, plug A1 and plug B3 are first stretched into automotive muffler exhaust pipe both ends, and open valve,
The compressed air that air source 4 generates is entered by air inlet 9 between outer tube 5 and inner tube 6, and is passed through gas vent 8 and entered in air bag 7,
Expand air bag 7, after air bag 7 expands, outer surface is close to the inner wall of automotive muffler, plays the role of sealing, plug A1
After interior air pressure with the air bag 7 of plug B3 all reaches setting value, the charging valve of tube wall air bag 7 is opened simultaneously on plug B3
Inner tube 6 on valve, make air source 4 generate compressed air enter in automotive muffler exhaust pipe, when automotive muffler be vented
When air pressure in pipe reaches 30 ± 3KPa, valve is closed, and suds are sprinkled on automotive muffler exhaust pipe, since automobile disappears
Sound device exhaust pipe both ends are blocked respectively by plug A1 and plug B3, so if automotive muffler exhaust pipe is there are air leakage point, then
Can occur bubble at air leakage point, if not occurring bubble, automotive muffler exhaust pipe can also be put into pond, detect gas leakage
Point marks after finding out air leakage point, and carries out repair welding to air leakage point, and air-tightness is rechecked, and completes to automotive silencing
The reparation of device exhaust pipe.
The outer tube 5 is externally provided with multiple gas vents 8, and the compressed air that air source 4 generates enters from gas vent 8 in air bag 7.
The outer tube 5 is equipped with air inlet 9, the compressed air that air source 4 generates from air inlet 9 enter outer tube 5 and inner tube 6 it
Between interlayer in.
The air inlet 9 is connect by valve with air source 4, air bag 7 can be controlled to expand by valve, by squeezing automobile
Muffler tail pipe inner wall is to have the function that sealing.
Inner tube 6 on the plug A1 is connect with air gauge 2, and air gauge 2 passes through the inner tube 6 and automotive silencing on plug A1
The inner cavity connection of device exhaust pipe can obtain the pneumatic parameter inside automotive muffler exhaust pipe, for judging vapour by air gauge 2
The detection air pressure of vehicle muffler tail pipe.
