Description
Technical field
The utility model relates to a kind of explosion-proof balanced valves.
Background technique
Because of security consideration, power battery just widely uses explosion-proof balanced valve, it is desirable that plays waterproof in normal work
Ventilative, pressure inside and outside balancing battery case effect is being abnormal (such as generation is hit or battery pack itself goes wrong)
When, the high-temperature gas in case can be quickly laid down, this requires explosion-proof balanced valves there must be specific explosion-proof mechanism.
Current explosion-proof mechanism is using destruction waterproof and breathable membrane structure therein or to use other methods by valve chest
With waterproof and breathable UF membrane two ways, such as: taper thimble punctures diaphragm, elastic construction bursting diaphragm etc..But above-mentioned two
Kind mode has some problems.
Taper thimble punctures diaphragm scheme, because of the batch wise differences of material, causes the tolerance of explosion-proof threshold range very big.Bullet
Property structure bursting diaphragm scheme, the usable frequency by spring or elastic slice are limited, and the service life of entire valve body is caused
It is limited.
Therefore, a kind of explosion-proof balanced valve is needed.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of explosion-proof balanced valve.
In order to achieve the above object, the technical solution of the utility model is as follows:
The utility model provides a kind of explosion-proof balanced valve, including shell, waterproof ventilated membrane, welding bar, sealing ring and upper cover,
Shell is equipped with multiple through-holes, and welding bar is circular ring structure, and the ring width size of welding bar is multiple continuous phases in its circumferencial direction
Welding ring segment even, welding the ring width size of ring segment from the both ends of its length direction to center is by small gradually big setting, welding bar
It is set on shell and is located at the outer ring of through-hole, waterproof ventilated membrane is set in welding bar, and sealing ring is set on shell, upper cover
It is sealed on shell.
The utility model compared to the prior art, changes the structure of welding bar on shell, waterproof ventilated membrane and shell into
Guarantee different from other positions in the welding structure of specific position when row welding, the anti-detonation pressure that product can bear is set with this
Power, achievees the effect that explosion-proof, and explosion threshold definitions are accurate, and tolerance is small, and precision is high, and welding bar is non-uniform circular ring structure,
Structure is simple, does not increase other blasting arrangements, reduces difficulty of processing, improves production efficiency.
Wherein, the difference for welding the maximum ring width size of ring segment and the minimum annular ring size of connection ring segment is 0.5-1.5mm.
Outer ring on shell and positioned at through-hole is equipped with shell bulge loop, and welding bar is set on shell bulge loop.
According to the actual situation, it can be selected that welding bar and shell are integrally formed.It is also an option that shell bulge loop is equipped with
Ditch ring is welded, welding bar is set on welding ditch ring.
In addition, the outer ring on shell and positioned at shell bulge loop is equipped with installing pipe, sealing ring is sheathed in installing pipe, and upper cover is close
Envelope is set in installing pipe.It is threadedly coupled or is clamped between upper cover and installing pipe.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Wherein, 1. shell, 2. welding bars, 3. sealing rings.
Specific embodiment
The preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
In order to reach the purpose of this utility model, as shown in Figure 1, being mentioned in one of embodiment of the utility model
For a kind of explosion-proof balanced valve, including shell 1, waterproof ventilated membrane, welding bar 2, sealing ring 3 and upper cover, shell 1 is equipped with multiple logical
Hole, welding bar 2 are circular ring structure, and the ring width size of welding bar 2 is multiple welding ring segments being continuously connected in its circumferencial direction, this
Embodiment is four welding ring segments being continuously connected, and the ring width size for welding ring segment is to center from the both ends of its length direction
By small gradually big setting, welding bar 2 is set to the outer ring on shell and being located at through-hole, and waterproof ventilated membrane is set in welding bar 2, close
Seal 3 is set on shell, and upper cover is sealed on shell.
Present embodiment compared to the prior art, changes the structure of welding bar 2 on shell 1, in waterproof ventilated membrane and shell 1
Guarantee different from other positions in the welding structure of specific position when being welded, the anti-detonation pressure that product can bear is set with this
Power, achievees the effect that explosion-proof, and explosion threshold definitions are accurate, and tolerance is small, and precision is high, and welding bar 2 is non-uniform circular ring structure,
Structure is simple, does not increase other blasting arrangements, reduces difficulty of processing, improves production efficiency.
Wherein, the difference for welding the maximum ring width size of ring segment and the minimum annular ring size of connection ring segment is 0.5-1.5mm.
Outer ring on shell 1 and positioned at through-hole is equipped with shell bulge loop, and welding bar 2 is set on shell bulge loop.
