Sensor probe 30, the first pressure probe and second pressure probe are electrically connected with the differential pressure pickup.
The first pressure probe is provided in first chamber, and the second pressure probe and the pH sensor control head are equal
It is set in the built-in core.
First pressure probe is for the coolant pressure before monitoring processing, and second pressure probe is for monitoring by three-level
Coolant pressure after reason, differential pressure pickup can judge whether water resistance meets system requirements according to the two pressure difference, will when exceeded
It is alarmed by sensor connector feedback signal to ECU or instrument, user is reminded to replace in time.
Such as coolant liquid is acidified simultaneously, and pH sensor probe can output signal to warning device, and warning device can export difference
Signal reminds user's maintenance to ECU or instrument.
It is provided with the first drainage plate 16 at the nearly radiator exhaust water pipe head in the expansion tank shell, in institute
It states and is provided with the second drainage plate 29 above built-in core, be to prevent coolant liquid straight for protecting built-in core design
The built-in core of impact is connect, is damaged.
The function of first chamber is the danger handled in the coolant liquid newly filled and the coolant liquid recycled in cooling system work
Evil substance and separation bubble do not enter second chamber and participate in cooling cycle, it is ensured that cooling system safe and highly efficient operation.
Second chamber is connected to filler by venting conduit, and 23 position of relief valve in venting conduit is lower than pressure cover
Sealing ring position, the effect of second chamber are vented for engine moisturizing and cooling system.
The working principle of expansion tank
As shown in figure 3, the daily filling of coolant liquid, it is only necessary to open the filling that pressure cover carries out coolant liquid, coolant liquid is first
First chamber is reached, second chamber is entered by communicating pipe after the three-level effect of built-in core processing, is that cooling system is defeated
Send cleaning and the coolant liquid of safety.
Relief valve in venting conduit is in close state before not reaching setting pressure, as shown in figure 4, when filling
When coolant liquid exceeds the water level line below minimum calibration points, the pressure area of a sealing is formed in the top area A of second chamber, it is empty
Gas principle is to make the function of built-in core to guarantee upper surface of the cooling level in first chamber always above built-in core
Effect maximizes.
In this application, built-in core is similar conical tube structure, and the outer diameter of upper surface is less than the outer diameter of lower end surface, purpose
It is also the surface area and effect for promoting built-in core, plays the role of double shield.After filling, coolant liquid height control exists
Between highest calibration points and minimum calibration points.
In order to which expansion tank reaches constant lasting treatment effect, and maintain coolant liquid pH value in constant range, sun
The volume of ion exchange resin layer is that cooling system fills 4th/3000 to thousand/1000ths of coolant liquid total measurement (volume), anion exchange
Resin layer is necessary for twice of cation exchange resin layer volume.
When cooling system pressure reaches setup pressure value, relief valve and pressure cover in venting conduit can be opened successively,
As shown in fig. 6, expansion tank completes exhaust pressure relief work, after cooling system pressure reduction, relief valve and pressure cover can be closed successively
It closes.
Built-in core working principle:
Level-one effect absorbs iron rust, scale and separation bubble by M type high molecular composite filtering paper layer 26.
Second level effect, acid ion etc. is disposed by anion exchange resin layer 27 and endangers ion, and generate hydrogen-oxygen from
Son.
Three-level effect, disposes calcium ion, magnesium ion, iron ion etc. by cation exchange resin layer 28 and endangers ion simultaneously
Generate hydrogen ion.
When cooling system works, coolant liquid is vented water pipe head, engine exhaust water pipe head into the by radiator
After one cavity area, first passes around M type high molecular composite filtering paper layer and complete iron rust, scale absorption and bubble isolation (prevention bubble
Cooling water circulation is participated in, heat dissipation performance is improved), using anion exchange resin layer, ion-exchange treatment falls acid ion, most
Afterwards by cation exchange resin layer, fallen by ion exchange the calcium ion in coolant liquid, magnesium ion, iron ion etc. endanger from
Son.
After coolant liquid is by the above tertiary treatment, hazardous substance is all disposed, second level effect and three-level effect
Hydroxyl ion and the hydrogen ion chemical reaction generated afterwards generates the deionized water harmless to cooling system, it is ensured that cooling system can pacify
Full persistent high efficiency operation.
The above is only the descriptions of the preferred embodiment of the present invention, it is noted that due to the finiteness of literal expression, and
Objectively there is unlimited specific structure, for those skilled in the art, is not departing from the principle of the invention
Under the premise of, several improvements and modifications can also be made, these modifications and embellishments should also be considered as the scope of protection of the present invention.
