Specific embodiment：
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the utility model discloses a kind of spiral case water pressure resistance test fixture, including the first sealing plate 11,
Second sealing plate 12, the 3rd sealing plate 13, the first valve 21, the second valve 22, flexible pipe 23, pressure gauge 24, screw rod 25 and sealing
Circle, a sealing ring is arranged at the import 100 of spiral case, and two sealing rings are arranged on the upper and lower ends of the outlet 200 of spiral case.The
One sealing plate 11 is sealedly connected in the import 100 of spiral case, and screw rod 25 is arranged in the outlet 200 of spiral case, the second sealing plate 12
Be threaded on screw rod 25 with the 3rd sealing plate 13, and the second sealing plate 12 and the 3rd sealing plate 13 seal against respectively in
The both sides up and down of outlet 200.First sealing plate 11, the second sealing plate 12 and the 3rd sealing plate 13 are by the bore seal of spiral case into
Individual closed cavity, the first valve 21, the second valve 22 and pressure gauge 24 are both secured on the first sealing plate 11, and the first valve
Door, the second valve and pressure gauge are connected with the inner chamber of spiral case, and flexible pipe 23 is connected on the first valve 21.
The circumferential wall of the screw rod 25 in the utility model is provided with boss 250, and the boss 250 is connected to the 3rd sealing plate 13
On.Sealing gasket is provided between the sealing plate 13 of boss 250 and the 3rd.
