Second chamber connects filler by venting conduit, and the position of relief valve 23 in venting conduit is less than pressure cover Sealing ring position, it is that engine moisturizing and cooling system are vented that the effect of second chamber is.
The operation principle of expansion tank
As shown in figure 3, the daily filling of coolant, it is only necessary to which opening pressure cover carries out the filling of coolant, and coolant is first First chamber is reached, is defeated cooling system by entering second chamber by communicating pipe after the three-level effect treatment of built-in core body The coolant for sending cleaning again safe.
Relief valve in venting conduit is closed before setting pressure is not reaching to, as shown in figure 4, when filling When coolant exceeds the waterline below minimum calibration points, a pressure area for sealing is formed in the top A areas of second chamber, it is empty Gas principle is to ensure upper surface of the ECL in first chamber always above built-in core body, making the work(of built-in core body Effect is maximized.
In this application, built-in core body is similar circular cone tubular construction, the external diameter of the external diameter less than lower surface of upper surface, purpose It is also the surface area and effect for lifting built-in core body, plays a part of double shield.After filling, coolant is highly controlled Between highest calibration points and minimum calibration points.
In order to expansion tank reaches constant lasting treatment effect, and coolant pH value is set to maintain in constant range, sun The volume of amberlite lipid layer is 4th/3000 to thousand/1000ths of cooling system filling coolant total measurement (volume), anion exchange Resin bed is necessary for the twice of cationic ion-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 the reduction of cooling system pressure, relief valve and pressure cover can be closed successively Close.
Built-in core body operation principle：
One-level is acted on, and iron rust, incrustation scale and separation bubble are absorbed by M type high molecular composite filterings ply of paper 26.
Two grades effect, by anion exchange resin layer 27 dispose acid ion etc. endanger ion, and produce hydrogen-oxygen from Son.
Three-level is acted on, and is disposed calcium ion, magnesium ion, iron ion etc. by cationic ion-exchange resin layer 28 and is endangered ion simultaneously Produce hydrogen ion.
When cooling system works, coolant enters the by radiator exhaust water pipe head, engine exhaust water pipe head After one cavity area, first pass around M type high molecular composite filterings ply of paper and complete iron rust, incrustation scale absorption and bubble isolation (prevention bubble Cooling water circulation is participated in, heat dispersion is improved), then by anion exchange resin layer, ion-exchange treatment falls acid ion, most Afterwards by cationic ion-exchange resin layer, fallen by ion exchange the calcium ion in coolant, magnesium ion, iron ion etc. endanger from Son.
By the way that after above tertiary treatment, hazardous substance is all disposed, two grades of effects and three-level are acted on coolant Hydroxyl ion and the hydrogen ion chemical reaction for producing afterwards generate 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 description of the preferred embodiment of the present invention, it is noted that due to the finiteness of literal expression, and Objectively there is unlimited concrete structure, for those skilled in the art, do not departing from the principle of the invention On the premise of, some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
