Pressurization simulation water depth testing device of sealing water tank and testing method

The invention discloses a pressurization simulation water depth testing device of a sealing water tank. The device comprises a tank body (1) with an upper opening, wherein a containing cavity is formed in the tank body (1); a tank cover (2) covers the tank body (1) and seals the containing cavity; a piezometer tube (3) is arranged on the bottom of the side wall of the tank body (1) and communicated with the containing cavity; a pressure gauge (4) is installed on the piezometer tube (3); and an inflation tube (5) is arranged on the seal cover and communicated with the containing cavity. The invention further discloses a testing method adopting the pressurization simulation water depth testing device of the sealing water tank. The device have the beneficial effects that the device can test various characteristic parameters of underwater equipment or devices at certain water depth pressure, overcomes the defects of adopting actual water depth verification and has good effectiveness and economy; and moreover, the
