1) The air outlet arranged on the side surface of the shell reduces the interference of the outside on the level (such as strong wind or external interference of chips, building falling stones and the like), so that the service life is longer, the precision is more accurate, and the structure of the original hydraulic static level is changed slightly (namely, the automatic exhaust valve is only required to replace the original manual exhaust valve);
2) The exhaust valve upper cover and the hollow pipe of the automatic exhaust valve can be connected with corresponding parts in a threaded mode, the ball with the stabilizer bar and the automatic exhaust valve body are convenient to operate and replace respectively, the static level with the automatic exhaust function is simple in structure and low in production cost, balls with different weights can be replaced according to the types of liquids with different bubble contents, therefore, even though the liquid with fewer exhaust bodies can automatically exhaust gas (the weight of the ball placed at the moment is lighter, such as 5g, the ball can be partially hollow at the moment), the liquid with more gas can also automatically exhaust gas (the weight of the ball placed at the moment is heavier, such as 10 g), and the automatic exhaust valve thoroughly meets various working conditions.
3) The ball below is provided with integrative stabilizer bar and has the effect of location, has both avoided unexpected deviate from hollow tube or block to the cavity of casing when the ball receives the pneumatic movement, and the stabilizer bar still makes the ball focus off downwards for the ball bottom can stabilize down when static and closely laminate with the closed loop and form seal structure, so this structure is particularly suitable for the liquid exhaust occasion of high accuracy measuring hydrostatic level.
