Description of drawings
Fig. 1 is the scheme drawing of Wet-type brake fluid charging machine of the present invention.
The specific embodiment
In conjunction with above-mentioned description of drawings specific embodiments of the invention.
As shown in Figure 1, a kind of brake fluid pipeline combined control system, this control system comprises Wet-type brake fluid charging machine, this charging machine comprises that change-over valve comprises first control electromagnetic valve 13, second control electromagnetic valve 14, by pass valve 60 and flow regulating valve 15; Described change-over valve 14, described by pass valve 60 and described flow regulating valve 15 are fixedly arranged on the module with hole, the circulation relationship between each valve of realizing being installed on it with the hole on the described module, this charging machine also comprises compression indicator; This compression indicator also can be installed on the described module.
This Wet-type brake fluid charging machine, comprise charging line 10, by-pass valve control 11 and filling gun 20 in this charging line 10 1 ends setting, the fluid injection case 30 that charging line 10 other ends are provided with, be in series with dispenser pump 40 and air-vent 50 from fluid injection case 30 successively to filling gun 20 directions on the described charging line 10, a flexible filler pipe 21 is set on 20 mouthfuls of filling guns.This charging machine also includes by pass valve 60, and this by pass valve 60 is parallel to dispenser pump 40, and the muzzle of filling gun 20 is provided with flexible filler pipe 21.This charging machine also includes braking liquid recovery system 70, this recovery system 70 comprises reclaim line 71, one end of this reclaim line 71 is provided with and reclaims mouth 72, an other end connects fluid injection case 30, be in series with first valve 73, first filter 74, second valve 75, fluid infusion case 76 and second filter 77 by fluid injection case 30 successively to reclaiming mouthful 72 directions on this reclaim line 71, a liquid level sighting tube is set in described fluid infusion case 76.Be connected with counter flow pipe 12 on the charging line 10 between described air-vent 50 and the by-pass valve control 11, an other end of this counter flow pipe 12 connects the outgate of by pass valve 60, and described counter flow pipe 12 is provided with first control electromagnetic valve 13.Be serially connected with second control electromagnetic valve 14 and flow regulating valve 15 on the charging line 10 between described by pass valve 60 and the air-vent 50.
Described air-vent 50 is calm jar 51, its principle of design is a physical phenomenon of utilizing the object stress deformation, when promptly object is subjected to power, as long as this power is no more than the elastic range of object self, after this power disappeared, object will return to stressed preceding shape.In braking liquid and Air mixing body, when being under pressure: the deformation coefficient of air is just bigger.And braking liquid is because the characteristics of itself, the coefficient of its distortion is very little, be almost 0, when these mixtures are under pressure, when mixed liquor (calm jar) when tiny pipeline is flowed through one the container that becomes suddenly big, make that the change in flow of braking liquid and gas is different, the gas of the pressurized formation air pocket that will expand suddenly, will merge the bigger bubble of formation between the bubble simultaneously, utilize calm jar particular design collection bubble also to emit automatically, just be easy to the tiny air separation that contains in the braking liquid is come out, guaranteed the pure of filling braking liquid, make braking performance of automobile reach good effect.
This equipment adopts gear type pump to pressurize to braking liquid, after the by pass valve voltage stabilizing, enter calm jar, braking liquid utilizes the special construction of air expansion principle and calm jar to eliminate tiny gas in calm jar, then through the control of electromagnetic valve, enter motor vehicle brake fluid through filling gun and store oil can, because the brake system UNICOM of this oil can and automobile, so braking liquid has also just entered the whole brake system of automobile, on the brake hub of 4 wheels of automobile, the exhausr port that a brake cylinder is respectively arranged, when opening exhausr port, air in braking liquid and the automotive system is discharged simultaneously, utilize one to be inserted in plastic pipe transparent on the exhausr port, the braking liquid of discharging is collected in the returnable bottle, observe the braking liquid that flows in the plastic pipe simultaneously, when the braking liquid that flows is represented the air emptying of brake system of car during in pellucidity, at this moment the operative employee can pull out transparent plastic pipe, closes exhausr port, presses the stop button of charging machine.
When the stop button of equipment is pressed, the output of the valve closing braking liquid of equipment pipeline, open braking liquid simultaneously and store the valve that the oil can liquid level is adjusted, carry out the liquid level adjustment that braking liquid stores oil can, rely on length-adjustable filler pipe on the filling muzzle, utilize the filling pressure that remains in the pipeline, make pipeline produce siphonage, when siphon is drawn onto the pasta in the oil can and the mouth of pipe of annotating when flushing, siphon disappears automatically, and whole filling process finishes.
Establish 2 oil circuit valve switchs (normally closed often opens) in the charging line system of charging machine, when brake fluid charging (normally closed opening, Chang Kaiguan closes), valve returned to normal when filling finished.In order to guarantee the generation of siphonage, must make the diff-H of a filler opening and oil return fuel tank.So we are placed on charging machine below the service platform, the electrolyte level difference that makes it both has 1000mm approximately.For the metal line of energy automatic compensation storage oil can, need stretch into the filler pipe that braking liquid stores scalable length in the oil can in one of design on the filling gun.
Design and produce a brake fluid charging platform on the auto production line side, the production car that hangs on this flat-bed height and manufacturing line bottom maintains an equal level, whole filling need of work 2 people operation, a people under a people, the car on the platform.Operator on the platform presses the button the equipment of starting as long as the filling gun braking liquid of screwing on is stored the oil can mouth, and the sound and light signal of equipment is reminded the operator below the production car that hangs, and brake fluid charging begins.Operator below the production car that hangs, the while can be opened the brake piping exhausr port of 4 wheels, observes the braking liquid of discharging from exhausr port, when braking liquid does not have bubble fully, close the braking liquid exhausr port, hull closures (halt switch be located at car at the bottom of next door) simultaneously, brake fluid charging finishes.The operator sees that sound and light signal closes on the platform, knows that braking liquid has been annotated to finish, and takes off filling gun, carries out the filling of next.Filling process of the present invention does not need brake piping is vacuumized, thereby has simplified loading system and operation, has reduced cost yet.
The present invention adopts change-over valve, by pass valve and flow regulating valve is fixedly arranged on the module with hole, thereby more saves the space and reduced pipeline and be connected.Make structure simpler like this, removed cost low, make with maintenance cost cheaper.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
