Abstract
A kind of rectangular cell chemical conversion seals one-way exhaust valve, the bottom of hollow valve core (2) and liquid injection hole are arranged in base (1) after closely cooperating, spring pedestal is welded to form by three supports (6.1) and support plate (6.2), the bottom of support is fixing with the inwall of hollow valve core to be connected, the bottom of spring (3) is fixedly connected on support plate, the top of spring is fixedly connected on the top cover (4) suitable with hollow valve core, arranges sealing ring (5) between described top cover and hollow valve core.By arranging spring and spring pedestal inside hollow valve core, the other end at spring arranges the top cover suitable with hollow valve core, can play the purpose of sealed valve core, when cell internal pressure reaches the pulling force more than spring, top cover can be backed down by gas, being released by internal gas, when cell internal pressure decreases below the pulling force of spring, top cover can be under the effect of the pulling force of spring, top cover presents closure state, simple in construction, low cost, practical.
Description
Technical field
This utility model relates to a kind of air bleeding valve, and specifically a kind of rectangular cell chemical conversion seals one-way exhaust valve, belongs to battery
Become technical field.
Background technology
Battery formation due to SEI film in formation process can produce more gas, for existing chemical conversion black box,
Have cannot aerofluxus, the quality of battery can be affected, some complex manufacturing technology, cost is high.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides a kind of rectangular cell chemical conversion to seal one-way exhaust valve,
While sealed cell liquid injection hole, can play the effect discharging internal gas, make Battery formation more abundant, SEI film is formed more
Perfect, extend the service life of battery, principle is simple, and production cost is low, practical.
To achieve these goals, this utility model provides the chemical conversion of a kind of rectangular cell to seal one-way exhaust valve, including with fluid injection
The close-fitting base in hole, also includes hollow valve core, spring and spring pedestal, the bottom of described hollow valve core and liquid injection hole
Arranging in the base after closely cooperating, spring pedestal is welded to form by three supports and support plate, the bottom of support and hollow valve core
Inwall fixing connect, the bottom of spring is fixedly connected on support plate, and the top of spring is fixedly connected on fits mutually with hollow valve core
On the top cover joined, sealing ring is set between described top cover and hollow valve core.
Base is plug.
Top cover is sheet metal.
Compared with prior art, this utility model by arranging spring and spring pedestal inside hollow valve core, another at spring
One end arranges the top cover suitable with hollow valve core, on the one hand can play the purpose of sealed valve core, on the other hand, work as battery
When internal pressure reaches the pulling force more than spring, top cover can be backed down by gas, is released by internal gas, works as cell internal pressure
When decreasing below the pulling force of spring, top cover can fall to, under the effect of the pulling force of spring, the position contacted with hollow valve core
Putting, top cover presents closure state, this utility model simple in construction, and low cost is practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, base, 2, hollow valve core, 3, spring, 4, top cover, 5, sealing ring, 6.1, support, 6.2,
Plate.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of rectangular cell chemical conversion seals one-way exhaust valve, including base 1 close-fitting with liquid injection hole,
Also include that hollow valve core 2, spring 3 and spring pedestal, the bottom of described hollow valve core 2 and liquid injection hole are arranged after closely cooperating
In base 1, spring pedestal is welded to form by three supports 6.1 and support plate 6.2, the bottom of support 6.1 and hollow valve core 2
Inwall fixing connect, the bottom of spring 3 is fixedly connected on support plate 6.2, and the top of spring 3 is fixedly connected on and hollow
On the top cover 4 that spool 2 is suitable, the sealing property overall in order to ensure this device, at described top cover 4 and hollow valve core 2
Between sealing ring 5 is set.
In order to reduce production cost and ensure the sealing of base 1 and liquid injection hole, elect base 1 as plug.
The purpose that top cover 4 is set to sheet metal is when cell internal pressure increases, and is easily ejected by top cover 4.
Top cover 4 of the present utility model in normal state, is the purpose playing and sealing hollow valve core 2, works as cell internal pressure
Increasing, when reaching the pulling force more than spring 3, top cover 4 can be backed down by gas, thus is released by internal gas, when in battery
When portion's pressure decreases below the pulling force of spring 3, top cover 4 can fall to and hollow valve under the effect of the pulling force of spring 3
The position that core 2 contacts, top cover 4 presents closure state, this utility model simple in construction, and low cost is practical.
