Problems solved by technology
[0004] Existing volutes such as figure 1 As shown, the volute needs to be subjected to a 0.8MPa pressure-holding hydraulic test for 1 hour according to the demand. Since the volute is open, it cannot hold water and has a complicated shape. It needs to be sealed by a test tool to form a closed container.
Existing test tooling has a complex structure, is not easy to load and unload, and has low labor efficiency

The invention discloses a water pressure resistance test device of a volute. The volute is provided with an inlet and an outlet. The device for testing the volute comprises a first sealing plate, a second sealing plate, a third sealing plate, a first valve, a second valve, a soft pipe, a pressure gauge, a screw rod and sealing rings. The sealing rings are arranged on the inlet and the outlet of the volute. The first sealing plate is sealingly connected to the inlet of the volute. The screw rod goes through the outlet of the volute. Both the second sealing plate and the third sealing plate are threadingly connected to the screw rod and sealingly lean against the upper and lower sides of the outlet. The cavity of the volute is sealed by the first sealing plate, the second sealing plate, and the third sealing plate to form a closed cavity. The first valve, the second valve and the pressure gauge are fixed to the first sealing plate, the first valve, the second valve and the pressure gauge communicate with the cavity of the volute, and the soft pipe is connected to the first valve.
Description
[0001] Technical field: [0002] The invention relates to a tool for testing water pressure resistance of a volute. [0003] Background technique: [0004] Existing volutes such as figure 1 As shown, the volute needs to be subjected to a 0.8MPa pressure-holding hydraulic test for 1 hour according to the requirements. Since the volute is open, it cannot hold water and has a complicated shape. It needs to be sealed by a test tool to form an airtight container. The existing test tooling has a complex structure, is inconvenient to assemble and disassemble, and has low labor efficiency. [0005] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. [0006] Invention content: [0007] The present invention provides a volute water pressure test tool in order to solve the above-mentioned problems in the prior art. [0008] The technical solutions adopted in the present invention include: a volute water pressure test tool, the volute is pro...
