Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model gas-tight test pressure observation device.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
See Fig. 1, gas-tight test pressure observation device of the present utility model include main connecting tube 1, arm 2, ball valve 3 and
Pressure gauge with bottom connection 4, described arm 2 is vertically welded in the middle part of main connecting tube 1, and described ball valve 3 one end is connected with arm 2, the other end
Being connected with described pressure gauge with bottom connection 4, described main connecting tube 1 one end is provided with a ready-packaged joint 5, and the other end is provided with a union joint 6, institute
Stating ready-packaged joint 5 to be also connected with the source outlet of nitrogen pipeline, described union joint 6 is by black glue pressure-bearing flexible pipe with preliminary examination pipeline even
Connect, described union joint 6 outer wall is formed one and is easy to the cannelure 7 hose connection with black glue pressure-bearing, and this union joint 6 is near main
One end of connecting tube 1 is set with a retainer ring 8, and described retainer ring 8 is circumferentially with multiple elastic pressure away from one end of main connecting tube 1
Sheet 9, described retainer ring 8 and multiple elastic pressuring plate 9 are made into integration, and are formed for black between multiple elastic pressuring plate 9 and union joint 6
The annular space that glue pressure-bearing flexible pipe inserts, described retainer ring 8 and multiple elastic pressuring plate 9 outer wall are also formed with external screw thread threaded
There is a nut 10.
The measurement scope of addressed pressure gauge with bottom connection 4 is 0-0.6MPa.
During test, the ready-packaged joint 5 of main connecting tube 1 one end is arranged on the source outlet ready-packaged joint of nitrogen pipeline
On, the union joint 6 of main connecting tube 1 other end is by black glue pressure-bearing flexible pipe and the pipeline (preliminary examination pipeline) being ready for air seal test
Air inlet is connected, the most black glue pressure-bearing flexible pipe plug-in mounting put in place after (the most black glue pressure-bearing flexible pipe is inserted to elastic pressuring plate 9 and union joint
After annular space between 6), rotate nut 10 to the side deviating from main connecting tube 1 so that nut 10 turns to multiple elastic pressuring plate 9
On, black glue pressure-bearing flexible pipe is then pressed on union joint 6 outer wall under the restriction of nut 10 by the most multiple elastic pressuring plates 9 further
On.Connect the locking pin of rear locking quick-mounting joint, first open nitrogen pipeline and give vent to anger valve, then open preliminary examination pipeline intake valve
Door, closes nitrogen pipeline and gives vent to anger valve, carry out pressurize test after pressure stability.During air seal test, by observing radially
It is intact that Pressure gauge 4 judges whether experimental line seals, if pressure gauge with bottom connection 4 registration five minutes is unchanged, proves to detect circuit
Sealing is intact.Air seal test terminates heel row and goes out gas, and this device is taken in locker.
In sum, content of the present utility model is not limited in the above embodiments, and those skilled in the art can
To propose other embodiment within technological guidance's thought of the present utility model, but these embodiments are included in this practicality newly
Within the scope of type.
