Preferably, the fastening device comprises a plurality of connecting rods, and two ends of each connecting rod respectively penetrate through the through hole connecting nuts arranged on the two flange plates.

Preferably, the flange plate connected with the water inlet pipe is also provided with a drain hole, the drain hole is communicated with the sealing cylinder, and the drain hole is connected with a drain valve. This arrangement allows the compressed air to be discharged while containing moisture.

Preferably, the sealing cylinder is made of a transparent material. The arrangement can facilitate the staff to observe the condition of the water delivery hose of the sealing barrel.

Compared with the prior art, the invention has the beneficial effects that:

this application can replace traditional 3 meters high water pipes of utilization completely to be pressed, and this application does not have the requirement to the device height, can effectively avoid receiving the defect of the indoor high restriction of factory building to the water gauge testing process.
