[0021] To make the purpose, content and advantages of the utility model more clear, the specific embodiment of the utility model is further described in detail below in conjunction with the drawings and examples.
[0022] The embodiment proposes a kind of breather installed in sealed non-volatile liquid tank, for balancing the internal and external pressure of sealed non-volatile liquid tank, guaranteeing the normal work of tank body, and preventing internal liquid from spilling due to vibration and the entry of external air large particle dust.
[0023] As Figure 1 And 2As shown, the breather installed on the sealed non-volatile liquid tank mainly comprises a breather base 1, a first breather static plate 2, a second breather static plate 3, a third breather static plate 4, a breather dynamic plate 5 and a breather cap 6. The breather dynamic plate 5 is welded on the top of the breather base 1, and a rotating piece is installed on the left side of the breather dynamic plate 5. The third breather static plate 4 is welded inside the breather base 1, and the distance between the third breather static plate 4 and the breather dynamic plate 5 is greater than the radius of the rotating piece on the breather dynamic plate 5. A plurality of breather holes are processed on the right half of the third breather static plate 4 for gas to enter and exit. The second breather static plate 3 is welded inside the breather base 1, and the distance between the second breather static plate 3 and the third breather static plate 4 is 0.1-0.8 times the diameter of the breather base 1. A plurality of breather holes are processed on the left half of the second breather static plate 3 for gas to enter and exit. The first breather static plate 2 is welded on the bottom of the breather base 1, and the distance between the first breather static plate 2 and the second breather static plate 3 is 0.1-0.8 times the diameter of the breather base 1. A plurality of breather holes are uniformly processed on the whole plate of the first breather static plate 2 for gas to enter and exit. The breather cap 6 is processed with threaded holes at both ends, and two fixing bolts 7 are screwed into the threaded holes and then screwed into the threaded blind holes on both sides of the breather base 1, so as to fix and connect the breather cap 6 with the breather base 1, and leave a gap between the edges of the breather base 1 and the breather cap 6. A 2mm concave table is processed in the radial direction from the bottom of the second breather static plate 3 to the bottom surface of the breather base 1, which is convenient for positioning and installation when welding on the tank body, and is welded and installed on the highest top surface of the sealed non-volatile liquid sealed tank body when in use.
[0024] As shown, Figure 3 The breather dynamic plate 5 comprises a fixed mortise plate 501, a rotating piece 502 and a fixed tenon 503. The fixed mortise plate 501 is processed with a circular opening on the left side of the center, and the diameter of the circular opening is smaller than the radius of the fixed mortise plate 501. The diameter of the rotating piece 502 is smaller than the diameter of the circular opening on the fixed mortise plate 501.

[0025] The working principle of the above-mentioned breather installed on the sealed non-volatile liquid tank is as follows:
[0026] When the internal pressure of the sealed non-volatile liquid tank decreases, the external air enters the top of the breather base 1 through the gap between the breather base 1 and the breather cap 6, and then passes through the rotating piece 502 on the breather dynamic plate 5, the third breather static plate 4, the second breather static plate 3 and the first breather static plate 2 in turn, and enters the inside of the tank body to balance the air pressure. When the internal pressure of the sealed non-volatile liquid tank increases, the internal gas can pass through the first breather static plate 2, the second breather static plate 3, the third breather static plate 4, the rotating piece 502 on the breather dynamic plate 5 and the gap between the breather base 1 and the breather cap 6 in turn, and then is discharged to the outside.
[0027] When the sealed non-volatile liquid tank inside the liquid occurs oscillation, the non-ventilation hole part of the first ventilation static plate 2, the second ventilation static plate 3, the third ventilation static plate 4 and the ventilation dynamic plate 5 can block the liquid, avoid the direct overflow of the liquid in the tank through the respirator, and the ventilation hole part can make the liquid oscillating in the ventilation attachment 1 backflow to the tank body; When there are large particles of dust in the external air, the ventilation cap 6 fixed on the ventilation attachment 1 can block the large particles in the air from entering the tank body through the ventilation hole, and avoid clogging the ventilation hole.
[0028] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and deformations can be made, and these improvements and deformations should be considered as the protection scope of the present application.
