Detailed description of the invention
The embodiment to valve air tight test device of the present invention that sees figures.1.and.2 is described further.
A kind of valve air tight test device, including tank 1, high pressure breather line 2 it is provided with in tank 1, the union joint 21 connected for valve it is provided with on described high pressure breather line 2, the present embodiment arranges on every high pressure breather line 2 multiple union joint 21, can disposably connect multiple valve, the drive mechanism driving high pressure breather line 2 to stretch out tank 1 it is provided with in described tank 1, described tank 1 is provided above visual safety device, described visual safety device is lamella lucida or protection network 6, and the present embodiment preferably uses protection network 6.
High pressure breather line 2 is taken out by tank 1, valve is made to be fastened on union joint 21, entirety is put into tank 1 the most again, protection network 6 covers above tank 1, in high pressure breather line 2, be passed through gases at high pressure, staff by protection network 6 can be safer observation valve air-tightness the most intact, protection network 6 has certain elasticity, when being impacted, certain cushioning effect can be played.
The preferred described drive mechanism of the present embodiment is cylinder 4, described tank 1 is provided above supporting gantry 3, described cylinder 4 is positioned on support gantry 3, described cylinder 4 connects high pressure breather line 2, described safety device connects cylinder 4, is provided with hollow pipe 5 between piston and the high pressure breather line 2 of described cylinder 4, and described safety device is fixed on hollow pipe 5 top, also include that trachea, described trachea are connected to hollow pipe 5 upper end.
By cylinder 4 can band dynamic high-pressure breather line 2 stretch into tank 1 in and stretch out outside tank 1, meanwhile protection network 6 will move up and down along with the piston of cylinder 4 and is subjected to displacement, protection network 6 and high pressure breather line 2 is made to remain a certain distance, connect hollow pipe 5 by trachea, just can be filled with gases at high pressure in high pressure breather line 2 by trachea and hollow pipe 5 valve is tested；Trachea is connected to hollow pipe 5 upper end, and protection network 6 also is secured to hollow pipe 5 upper end, then actual trachea is arranged by protection network 6, and when cylinder 4 is up and down, trachea moves with protection network 6, it is to avoid trachea in disorder obstruction staff dismounts valve.
