Connect, the internal diameter of the flange blind hole is identical with the internal diameter of outer wall pipe and inner wall tube, flanged plate side be provided with respectively with the method
The first side opening and the second side opening that tritonope hole both sides communicate, first side opening is connected with pressure gauge, the second side opening connection
There is ball valve, the ball valve other end is connected with compressed air.
Used as the further improvement of such scheme, the flanged plate edge offers several bolts hole, and flanged plate passes through
Several bolts are arranged on outer wall pipe or inner wall tube.
Used as the further improvement of such scheme, the ball valve other end is connected with compressed air hose, the compressed air
Manage external gas booster pump.
The beneficial effects of the utility model are：This test fixture is provided with pressure gauge and ball valve, flange on its flanged plate
Plate may be installed at fuel gas inlet, and ball valve control is passed through gas, and pressure gauges measure pressure value, the utility model can not only be effective
Detect whether Gas Pipe leaks, it is and simple structure, easy to operate, be favorably improved the operating efficiency of test.

Whether detection outer wall pipe leaks：The first mounting O-shaped sealing ring on outer wall pipe, then test fixture is arranged on outer wall pipe
On, compressed air hose is connected on ball valve, ball valve is opened to being pumped in pipe, the pressure value on the pressure gauge of test fixture
Work ball valve is closed when reaching 22.5Bar, then checks whether all Guan Yuguan, pipe bubble occur with the junction of valve using leak test agent
Foam, while the pressure gauge observed on test fixture is also required to, if pressure change less, illustrates that outer wall pipe does not have within 15 minutes
Occur leakage.
Whether detection inner wall tube leaks：First O-ring seal is respectively mounted on inside and outside wall pipe, then test fixture is installed,
Simultaneously by inner gas outlet with silently dismantling so that outer wall pipe gas can be run out of from this.Test fixture installation
Afterwards, compressed air hose is connected on the ball valve on test fixture, ball valve is opened to being pumped in pipe, when pressure value reaches
Ball valve is closed during 22.5Bar, is checked at inner gas outlet and with silently locating whether foam occur using leak test agent, while
The pressure gauge observed on test fixture is needed, if pressure change less, illustrates that letting out does not occur in inner wall tube within 15 minutes
Leakage.
Described above-described embodiment is that the above of the present utility model is further described, but should not be interpreted as this
