The hydraulic static level gauge is a high-precision liquid level measuring instrument based on the principle of a communicating vessel, and is suitable for detection occasions requiring high-precision vertical displacement or settlement deformation. The problem of settlement is further known through the effect of the pressure of the liquid in the level gauge on the sensor and the vertical height of the analysis level gauge of the sensor. If gas is not timely discharged in the hydraulic static force level, the measurement of water pressure is affected, the vertical settlement height of the level cannot be really obtained, the precision of the level is affected, and potential safety hazards of buildings can be generated. The existing hydraulic static level needs manual exhaust treatment before measurement, and is relatively troublesome and time-consuming. Based on foretell problem, the utility model discloses improved on the quiet power level appearance that needs artifical exhaust before, replaced the valve that has the self-bleeding function of a great deal of advantage with the automatic exhaust valve door to make the automatic exhaust valve door be particularly suitable for fluid pressure type quiet power level appearance.
Referring to fig. 1 and 2, the present invention provides a hydraulic static level with an automatic air discharge function, the hydraulic static level 8 comprises an automatic exhaust valve, the automatic exhaust valve comprises a valve shell 6, an exhaust valve upper cover 7, a closed ring 5 and a small ball 4 with a stabilizer bar, the valve shell 6 is detachably connected with an upper cover 7 of the exhaust valve, the upper part of the valve shell 6 is provided with an air outlet 2, the lower part of the valve shell 6 is provided with a hollow tube 3 communicated with the liquid level of the internal liquid 9 of the static level gauge, the air inlet 1 at the bottom of the hollow pipe 3 is communicated with the air outlet 2 through a cavity in the valve shell 6, the closed ring 5 is fixed on a funnel-shaped slope at the upper end of the hollow tube 3, and the small ball 4 with the stabilizer bar is placed into the hollow tube 3, so that the small ball is tightly attached to the closed ring 5.
In another embodiment, the funnel-shaped slope at the upper end of the hollow tube 3 is provided with an annular groove for fixing the closed ring 5, and the closed ring 5 (black dots in the figure) may be preferably a rubber ring or a silica gel pad, and may also be other corrosion-resistant elastic materials. It is worth mentioning that the air inlet should extend below the internal liquid level of the hydrostatic level as far as possible in order to allow the gas generated in the liquid to be discharged in time.
In another embodiment, the air outlet 2 is arranged on the side surface of the upper part of the valve housing 6, so that the air outlet is prevented from being blocked due to airflow or accumulation of impurities such as dust in air, and the automatic exhaust function of the level gauge is further prevented from being influenced, in addition, the number of the openings of the air outlet 2 can be preferably multiple, the valve housing 6 is made of stainless steel, and the service life of the static level gauge can be prolonged and the stability of the use precision of the static level gauge can be improved due to the fact that the working environment of the static level gauge is in long contact with liquid.
In another embodiment, the stabilizer bar and the small ball on the small ball 4 with the stabilizer bar are integrally formed, of course, the stabilizer bar and the small ball can be detachably connected, in addition, the surface material of the small ball 4 with the stabilizer bar is preferably stainless steel, so that the small ball is durable, the lower end of the small ball with the stabilizer bar can be perfectly connected with the closed ring, further, the liquid loss is avoided, the stability of the internal pressure is kept, the stabilizer bar can avoid the vibration influence caused by the environment and the shaking influence caused by violent construction reduction, the liquid in the level instrument flows out, and the stability of the small ball in the working state can be improved by the stabilizer bar.

In addition, the outer wall of the upper cover of the exhaust valve is polygonal (not shown in figures 1-2), so that manual rotation and disassembly are facilitated.
The following is for making clear the utility model discloses an advantage will introduce the working method that has the fluid pressure type hydrostatic level of self-bleeding function in detail:
from the above, the automatic exhaust valve can form two working conditions, one: when no gas is in the hydraulic static level, the small ball 4 with the stabilizer bar seals the hollow tube 3, and the second step is that: when gas is generated inside the hydraulic static level 8, the small ball with the stabilizing rod meeting the gravity setting requirement is jacked upwards, and the gas is discharged from the hollow pipe through the gas outlet 2 from bottom to top. This static force level 8 has used automatic exhaust valve to replace manual exhaust screw or manual exhaust valve, and the condition that two kinds of corresponding operating modes produced can be calculated to the gaseous circulation condition in the analysis valve during the exhaust to according to the bobble 4 of the stabilizer bar of different weight of demand design.
Specifically, when exhausting, because produce gas in the instrument, the inside pressure increase of hydrostatic level, because the pressure effect, 4 upsets of bobble with the stabilizer bar, gas upwards discharges through the space between hollow tube 4 and the bobble 4 of taking the stabilizer bar, discharge from gas outlet 2 again, gas outlet 2 sets up in the side of the upper portion of valve housing 6, reduce because inside the jam of gas outlet that impurity factors such as dust caused among the operational environment and enter into hydrostatic level, and the influence of the precision that causes, thereby reach the automatic gaseous purpose of discharging. After the gas that liquid produced in the spirit level is discharged, the pressure in the instrument reduces, and the ascending power that the bobble 4 that takes the stabilizer bar received reduces, falls back again through the guide effect of stabilizer bar, and complete accurate laminating contact once more with the closed ring closes the valve for inside liquid does not run off, and outside impurity can not get into.
The utility model discloses fluid pressure type hydrostatic level with self-bleeding function's beneficial effect includes:
1) the gas generated in the hydraulic static level can be automatically and timely discharged, the manual exhaust link is reduced, the measurement cost is reduced, the gas outlet arranged on the side surface of the shell reduces the interference of the outside on the level (such as strong wind or debris, building falling rocks and other external interference), the service life is longer, the precision is more accurate, and the change of the original hydraulic static level structure is small (namely, only an automatic exhaust valve is required to replace the original manual exhaust valve);
2) automatic vent valve's exhaust valve upper cover and hollow tube can adopt the screw thread mode and correspond the part and be connected, the bobble and the automatic vent valve body of taking the stabilizer bar are changed to convenient operation respectively, and this kind of static level appearance simple structure that has the automatic exhaust function, low in production cost, can change the bobble that the weight is different according to the type that contains the different liquid of bubble volume, thereby even make the less liquid of exhaust gas can get rid of gas voluntarily (the bobble weight of placing this moment is lighter, like 5g, the bobble can be partly hollow this moment), gas (the bobble weight of placing this moment is heavier, like 10g) also can be got rid of gas voluntarily to the more liquid of gas, make automatic vent valve thoroughly satisfy various operating.
3) The stabilizer bar arranged below the small ball has a positioning effect, so that the small ball is prevented from accidentally dropping out of the hollow pipe or being clamped into the cavity of the shell when the small ball moves under air pressure, the gravity center of the small ball is deviated by the stabilizer bar, and the bottom of the small ball can be stably attached to the closed ring downwards to form a sealing structure when the small ball is static, so that the structure is particularly suitable for the liquid exhaust occasions of the hydraulic static level instrument for high-precision measurement.
