Abstract
The utility model discloses an accumulator safety valve, which comprises a valve body, a valve body sealing ring, a valve cap and a valve cover; and is characterized in that: a top valve cover is pressed on the valve cap; a first air outlet is formed on between the mating surfaces of the overhead-valve cover and the valve body; the valve cavity lower end of the valve body is sealed; and a second air outlet is formed on the valve cavity wall. In the utility model, the first air outlet is formed on between the mating surfaces of the overhead-valve cover and the valve body, while the valve cavity lower end of the valve body is sealed, and a second air outlet is formed on the each of the two sides for causing the gas entered into the valve body to generate pressure difference; then, the gas is caused to generate helical form by the slope effect; and the liquid carried by the gas is converged into drops. when the pressure inside the accumulator reaches a certain value, the valve cap opens instantly to discharge gas, then closes instantly; the converged drops falls naturally back into the accumulator because the pressure in the valve reduces quickly, thereby, gas-liquid separation effect is achieved.
Description
Technical field
The utility model relates to a kind of storage battery, especially the safety valve of valve controlling type accumulator.
Background technology
Safety valve is a vitals of valve controlling type accumulator, and its performance directly has influence on the life-span of storage battery.Its operation principle is: when the gas pressure of inside battery was raised to certain value, the bonnet in the safety valve can be opened exhaust automatically, and when internal gas pressure dropped to certain value, bonnet can be closed automatically, thereby had protected accumulator property.But this through type safety valve has also been taken away a part of liquid when discharging gas, go down to cause the battery dehydration serious for a long time, influences the useful life of storage battery.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of accumulator protection valve, when bonnet is opened exhaust automatically, can not take away the liquid in the battery, has not only protected storage battery to have good performance, and has prolonged the useful life of storage battery.
The utility model is achieved through the following technical solutions:
A kind of accumulator protection valve, comprise by valve body, valve seals, bonnet, valve gap being assembled that characteristics are to be pressed with the overhead-valve lid on bonnet, are provided with first venthole between the mating surface of overhead-valve lid and valve body, the valve pocket lower end of valve body is a sealed shape, and valve cavity wall is provided with second venthole.
The further improvement project of the utility model is, second venthole is arranged on the relative two side of valve pocket, one of them is arranged on the domatic top end wall, and another is arranged on the wall of domatic bottom, and the second venthole position on the domatic top end wall is higher than second venthole on the domatic base end wall.
The further improvement project of the utility model is, the overhead-valve side of covering is provided with filter acid film, and described filter acid film and valve body are for closely cooperating.
The utility model is pressed with the overhead-valve lid on bonnet, overhead-valve lid bottom has cylindrical boss to push down bonnet, and bonnet lip limit and valve body surface are fitted tightly.Between the mating surface of overhead-valve lid and valve body, be provided with first venthole, simultaneously the valve pocket lower port of valve body is sealed, and it is set to domatic, second venthole is set on its two side, make the gas that enters valve body produce pressure differential, through the effect on slope, make gas produce helical form again, the liquid that gas carries pools drop.When internal storage battery pressure reached certain value, bonnet can moment be opened discharge gas, can close moment again then, the liquid that converges since the pressure sharp fall in the valve will the drippage of nature under, get back in the storage battery, thereby played the effect of gas-liquid separation.

Embodiment:
As shown in Figure 2, a kind of accumulator protection valve comprises by valve body 1, valve seals 2, bonnet 3, valve gap 6 being assembled.Still as shown in Figure 2, be pressed with overhead-valve lid 4 on bonnet 3, overhead-valve lid 4 is an interference fit with valve body 1, is provided with two first ventholes 8 between the mating surface of overhead-valve lid 4 and valve body 1, and described first venthole 8 is symmetricly set in overhead-valve and covers on the valve body 1 in 4 one weeks.Still as shown in Figure 2, overhead-valve covers 4 tops and is provided with filter acid film 5, and described filter acid film 5 and valve body 1 are for closely cooperating.
As shown in Figure 1, 2, valve pocket 7 lower ends of valve body 1 are that the lower surface of sealed shape, sealed shape is domatic, and domatic vertical angle is the 15-50 degree, and domatic in the present embodiment vertical angle is elected 25 degree as.Still as shown in Figure 1, 2, valve pocket 7 relative two sides are provided with second venthole 9, one of them is arranged on the domatic top end wall, and another is arranged on the wall of domatic bottom, and second venthole, 9 positions on the domatic top end wall are higher than second venthole 9 on the domatic base end wall.
