Pressurizing simulation water depth test apparatus for sealed water tank

Disclosed in the utility model is a pressurizing simulation water depth test apparatus for a sealed water tank. The test apparatus comprises a box body (1) with an upper opening; and an accommodation cavity is arranged in the box body (1). A box cover (2) for sealing the accommodation cavity seals and covers the top of the box body (1); a piezometer tube (3) communicated with the accommodation cavity is arranged at the bottom of the side wall of the box body (1); a pressure gage (4) is installed at the piezometer tube (3); and a gas filled tube (5) communicated with the accommodation cavity is arranged at the sealing cover. According to the utility model, the beneficial effects of the apparatus are as follows: various characteristic parameters of an underwater device under the certain water depth pressure can be verified; a defect caused by utilization of an actual water depth verification method can be overcome; and the provided apparatus has the good effectiveness and economy. Moreover, the provided test ap
