Abstract
The utility model discloses a kind of deep-sea one-way ventilating valves, spool and O-ring seal including valve body and set on body cavity, contact surface between the inner cavity top and spool is taper surface, the valve body bottom end is provided with casing and the spring in casing, and the spring is fixed on by adjusting nut on valve body；The lower end of spool is thread segment, adjusting nut can be moved in spool upper edge thread segment spiral, spring is between adjusting nut and valve body, adjusting nut can on spool moving in rotation, by movement of the adjusting nut on spool, to adjust the reduction length of spring, so as to the elastic force of adjustment spring, the Opening pressure of one-way ventilating valve is adjusted by the size of elastic force, and then adjusts the Opening pressure value of deep-sea one-way ventilating valve；O-ring seal is pressed on the taper surface of valve body and is sealed by spool, can bear deep-sea external high pressure No leakage, and available for abyssal environment, one-way ventilating valve is backwards to the external pressure No leakage that can bear 6Mpa.
Description
Technical field
The utility model is related to one-shot battery technical field, more particularly to a kind of deep-sea battery one-way ventilating valve.
Background technology
For certain reserve cells in long-term storage process, inside battery material, which can slowly decompose, generates gas, long
Time, which generates gas, cell internal pressure to be caused to increase, and so as to change inside battery structure, influence the electrical property of battery.
To extend the storage time of battery, the service life of battery is improved, by increasing one-way ventilating at battery case
Valve, when cell internal pressure is more than the Opening pressure value of one-way ventilating valve, one-way ventilating valve is opened, and discharge inside battery generates
Gas.
For one-shot battery in water, especially deep-sea battery, with the increase of the depth of water, the pressure of external environment gradually increases
Add.
Deep-sea one-way ventilating valve needs bear external pressure without sealing leak occurs, in case seawater enters battery
Inside influences battery performance.The internal pressure of one-shot battery in water can be adjusted at any time by one-way ventilating valve simultaneously, prevent water
The housing of middle battery leads to casing rupture due to pressure difference is excessive.
Utility model content
The purpose of this utility model is to provide the deep-sea one-way ventilating that one kind can bear high external pressure and one-way ventilating
Valve.
Technical solution is used by the utility model solves its technical problem：A kind of deep-sea one-way ventilating valve, including
Valve body and the spool and O-ring seal set on body cavity, the contact surface between the inner cavity top and spool are taper
Face, the valve body bottom end are provided with casing and the spring in casing, and the spring is fixed by adjusting nut
On valve body.
A kind of deep-sea one-way ventilating valve, the contact surface between intracavity bottom and spool are boss face.
A kind of deep-sea one-way ventilating valve, adjusting nut upper end are boss face.
The spring one end is sleeved on the boss face of valve body, and the other end is sleeved in the boss face of adjusting nut.
The utility model has the advantage that as follows with good effect：
O-ring seal by spool is pressed on the taper surface of valve body and is sealed by the utility model, can be made unidirectional saturating
Air valve bears the external pressure of 6Mpa without revealing；It can be used to adjust the gas pressure of inside battery on reserve cell, extend storage
The reserve time of standby battery extends the service life of battery；Simple in structure, reliability is high, available for batch equipment production.
Description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the structure diagram of the utility model valve body；
Fig. 3 is the structure diagram of the utility model adjusting nut.
Each reference numeral is：1-valve body, 11-taper surface, 12-boss face, 2-O-ring seal, 3-spool, 4-bullet
Spring, 5-adjusting nut, 51-boss face, 52-internal thread, 6-casing.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1 to Figure 3, the deep-sea one-way ventilating valve of the utility model, including valve body 1, O-ring seal 2, spool
3rd, spring 4, adjusting nut 5, casing 6, for O-ring seal 2 between valve body 1 and spool 3, spring 4 is located at adjusting nut 5 and valve
Between body 1, adjusting nut 5 moving in rotation, casing 6 can be threadedly attached in the lower end of valve body 1 on spool 3；Valve body 1
Inside contact surface in have one section of contact surface for taper surface 11, there is a boss face 12 in lower end, and the upper end of adjusting nut 5 is boss face
51, the inside of adjusting nut 5 is internal thread 52.
One end of spring 4 is sleeved in the boss face 51 of adjusting nut 5, and the other end is sleeved on the boss face 12 of the lower end of valve body 1
On.It is moved on spool 3 by rotating adjusting nut 5, to adjust the elastic force of spring 4.By the elastic force of spring 4 by O-shaped sealing
Circle 2, which is pressed on the taper surface 11 of valve body 1, to be sealed, so as to which the gas outside one-way ventilating valve be made to cannot be introduced into inside battery；
When the thrust magnitude that the air pressure of inside battery is applied on adjusting nut 5 is more than the resultant force value on spool 3（The elastic force of spring 4+O-shaped
Stiction+external pressure of sealing ring 2 is applied to the power on spool 3）, spool 3 begins to move up, and one-way ventilating valve is beaten
It opens, discharges internal gas.
When one-way ventilating valve is run with deep-sea battery apparatus in deep-sea, external pressure of the one-way ventilating valve in 6Mpa acts on
Under, push rod 3 is pushed to move down, O-ring seal 2 is with the increase of pressure, and decrement is bigger, and sealing effect is better.
The implementation that the principles and effects of the utility model creation are only illustrated in above-described embodiment and part uses
Example, rather than limits the present invention；It should be pointed out that for those of ordinary skill in the art, this reality is not being departed from
Under the premise of being conceived with novel creation, various modifications and improvements can be made, these belong to the protection model of the utility model
It encloses.
