Description
Technical field
The present invention relates to check valve apparatus technical fields, specially a kind of to can control the unidirectional of coolant liquid one-way flow
Valve.
Background technique
Currently, electric automobile power battery is lithium ion battery, lithium-ion-power cell is more sensitive to temperature change, with
Requirement of the people to course continuation mileage number be continuously improved, the battery pack of greater number is discharged in close loading space.When
When driving with friction speed checker, battery can be discharged automobile with different multiplying, and discharge process can generate amount of heat, at this time
Coolant liquid is needed to carry out circulation temperature lowering, check valve plays control one-way flow, prevents coolant liquid from flowing back in coolant line
Effect, entire liquid cooling cooling system circulation are obstructed, and non-uniform heat flocks together, and will directly affect efficiency, the electricity of battery
Pond service life and use are safe.
One-way valve structures at present on the market are more, and the disassembly and assembly time of check valve is caused to lengthen, and repair cumbersome, check valve
Generally metal material, heavier-weight, therefore it is badly in need of a kind of check valve that can control coolant liquid one-way flow in the market to solve
The certainly a little problems of this people.
Summary of the invention
The purpose of the present invention is to provide a kind of check valves that can control coolant liquid one-way flow, to solve above-mentioned background
The one-way valve structures proposed in technology are more, cause the disassembly and assembly time of check valve to lengthen, repair cumbersome problem.
To achieve the above object, the invention provides the following technical scheme: a kind of list that can control coolant liquid one-way flow
To valve, including cooling liquid water inlet pipe and unidirectional valve body, check-valve body, the check valve are provided on the unidirectional valve body
One end of shell is provided with cooling fluid through-hole, and the check-valve body is internally provided with gutter, the check-valve body
Both ends are provided with straight pin through-hole, and the gutter is internally provided with straight pin, and the both ends of straight pin are each passed through circle
Pin through-hole, the side of the straight pin are provided with baton round, and the external setting check valve of described check-valve body one end limits
Convex block, the outside of described straight pin one end are provided with cylinder spacing block set, and the side of the cooling liquid water inlet pipe is provided with cooling
Liquid outlet pipe is provided with coolant liquid capillary, the unidirectional valve body between the coolant liquid outlet pipe and cooling liquid water inlet pipe
There are two settings, and two unidirectional valve bodies are located at the inside of cooling liquid water inlet pipe and coolant liquid outlet pipe, the cooling
The outside of liquid capillary is provided with battery cell, and there are four battery cell settings.
Preferably, the diameter of the baton round is greater than the latus rectum of cooling fluid through-hole.
Preferably, the diameter of the cylinder spacing block set is greater than the latus rectum of straight pin through-hole.
Preferably, there are four the coolant liquid capillary settings, and four coolant liquid capillaries are sequentially distributed.
Preferably, the inner surface of the battery cell and the outer surface of coolant liquid capillary fit.
Preferably, the coolant liquid capillary is tightly connected with cooling liquid water inlet pipe and coolant liquid outlet pipe.
Preferably, the check valve application method the following steps are included:
Step 1: baton round is fitted into gutter, then straight pin is assemblied in straight pin through-hole just realizes cooling fluid through-hole
Assembling.
Step 2: unidirectional valve body to be connected to the interface of cooling liquid water inlet pipe and coolant liquid outlet pipe, gold is reused
Belong to material pipe collar firmly to connect the pipeline for passing in and out water channel with unidirectional valve body, whereby to achieve the effect that connection, just complete
The installation of unidirectional valve body.
Step 3: coolant liquid is flowed into unidirectional valve body, by weight when coolant fluid is inputted from cooling fluid through-hole forward direction
The baton round of power factor is separated with check-valve body sealing surface, and unidirectional valve body is in the open state, when the pressure mistake of coolant liquid
When big, straight pin will limit the movement position of baton round, and baton round is stopped to be detached from.
Step 4: when coolant liquid flows back, reaction force of the baton round by fluid, baton round and check-valve body sealing surface
Sufficiently fitting, has blocked cooling fluid through-hole, and unidirectional valve body is in closed state, limits the reflux of coolant fluid, thus
It solves fluid to liquidate phenomenon, keeps battery pack liquid cooling cooling system circulation smooth, reach optimal cooling effect.
Compared with prior art, the beneficial effects of the present invention are:
1. the check valve that can control coolant liquid one-way flow compares the metal check valve of same performance, metal check valve is minimum
Five components are needed to be assembled, structure is also complex, and three components are only used only in the present invention, meets same requirement
In the case where, cost accomplishes minimum, operation and using also the simplest.It assembles a metal check valve and takes around 25
Second, the plastic material designed herein unidirectionally takes around five seconds, and efficiency improves about five times.Removing a metal check valve about needs
Want 20 seconds, the plastic material designed herein unidirectionally takes around four seconds, efficiency improve about five times, solve one-way valve structures compared with
It is more, it causes the disassembly and assembly time of check valve to lengthen, repairs cumbersome.
2. this can control coolant liquid one-way flow check valve be entirely by plastic pellet injection molding, it is light-weight
Be full of, in battery pack liquid cooling cooling system use 1PCS check valve, 2 points 3 grams, one of the metal check valve of equivalent constructions
About four. 3 grams of the check valve of plastic material or so, this reduces secondly ten grams of weight, on light-weighted road again
An important step is stepped, while check valve mainly uses in the cooling system with automobile, the main ingredient of coolant liquid is second two
Alcohol, using metal material check valve when, since different metal electrode potential is different, be easy to produce electricity under the action of electrolyte
Chemical reaction generates the defects of corrosion.The check valve uses plastic material, has the characteristics that stable chemical performance, plastics for
General acid, alkali, salt and grease have preferable corrosion resistance, under being stored in 135 degree of High-temperature cooling, without any
Bad phenomenons, the service life such as corrosion and surface defect have obtained better guarantee.
