Specific embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the present invention 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 ring, one
Individual 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.First is close
Shrouding 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 and
Three sealing plates 13 are threaded on screw rod 25, and the second sealing plate 12 and the 3rd sealing plate 13 are sealed against respectively in outlet
200 both sides up and down.First sealing plate 11, the second sealing plate 12 are close into one by the bore seal of spiral case with the 3rd sealing plate 13
The cavity for closing, 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,
Two valves 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 present invention is provided with boss 250, and the boss 250 is connected on the 3rd sealing plate 13.
Sealing gasket is provided between boss 250 and the 3rd sealing plate 13.
Nut is connected with the threaded upper ends of screw rod 25, the nut is connected on the second sealing plate 12, in nut and second
Sealing gasket is provided between sealing plate 12.
For ease of rotary screw 25, wear in the lower end of screw rod 25 and be connected to rotating handles 4.
Test process is as follows：
Flexible pipe 23 is connected into running water tap, the first valve 21 and the second valve 22 is opened, is noted in the inner chamber of spiral case
Enter tap water, disconnect tap water connection after beginning with water at the second valve 22 and uniformly flowing out.By the second valve 22 with it is portable
Hydraulic pressure test pumps out mouth of a river docking, opens the second valve 22, to water filling in spiral case, boiled water press pump treats that 23 mouthfuls of flexible pipe begins with water
It is uniform flow out after the first valve 21 is closed, hydraulic pamp continues supercharging, and by spiral case and frock surface is water stain dries, when pressure it is steady
When increasing to 1MPa surely, pressurize 5S is unloaded afterwards and is pressed onto 0.8MPa, then pressurize 1 hour.Pressure maintaining period observation spiral case outer surface whether there is
It is water stain to ooze out or deform, represent that spiral case voltage-withstand test is unqualified if having, rises is marked with painting pen；If to guarantor
Pressure terminate all be not observed it is water stain ooze out or deform generation then expression spiral case voltage-withstand test it is qualified.Pressurize is opened after terminating
Water in spiral case is excluded after terminating by hydraulic pamp pressure release, pressure release by the first valve 21 and the second valve 22, removes test fixture, inspection
Surveying frock has not damaged and keeps well；Qualified spiral case is beaten into qualified label and interval of acceptance is placed on, test terminates.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, these improvement also should be regarded as the present invention's
