Automatic draining device in salt spray test box

Abstract

The invention discloses an automatic draining device in a salt spray test box. The automatic draining device comprises a bottom plate in the salt spray test box, a conical sinking platform is formed on the bottom plate by bending, a water leaking hole is formed in the undersurface of the sinking platform, a draining seat communicated with the water leaking hole is fixed on the undersurface of thesinking platform, a step hole penetrating the upper end face of the draining seat is formed on the undersurface of the draining seat, a draining hole communicated with the step hole is formed in the outer side wall opposite to the lower end of the draining seat, a T-shaped sealing plug is connected in the step hole of the draining seat in an inserted manner and composed of a head portion and a handle portion, the head portion of the sealing plug is connected in the water leaking hole of the bottom plate in an inserted manner while the handle portion penetrates the draining seat to be fixed toa floating ball, a lower permanent magnet ring and an upper permanent magnet ring sleeve the handle portion of the sealing plug in an inserted manner, the upper permanent magnet ring is fixed on a step face of the step hole of the draining seat, and the lower permanent magnet ring is fixed on a step face of the sealing plug. The automatic draining device can realize an automatic draining function,and impact on a test result of a test piece caused by the fact that accumulated water level of the test box goes up to submerge the test piece is avoided.

Description

Technical field: [0001] The invention relates to the technical field of detection equipment for automobile radiators, in particular to an automatic drainage device in a salt spray test chamber. Background technique: [0002] The salt spray test chamber is a kind of equipment for external corrosion test, and it is the necessary test equipment for some automobile radiator manufacturers. When the salt spray test chamber is used for the external corrosion test, a certain amount of water needs to be placed inside the test chamber, so that the temperature in the test chamber can be increased by heating the water, while the salt spray test chamber is used to spray salt spray into the test chamber. Sedimentation will increase the amount of water at the bottom of the test box, and the salt spray test period is longer, and the spray time is longer, so that the water level at the bottom of the test box will gradually rise to the test piece, affecting the test results of the test piece,...
