Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
With reference to figure 1 and Fig. 2, the parallel pipe pressure balance valve for internal combustion engine extra feed tank comprises extra feed tank 1, left water cavity 2, spring 3, valve body 4, spool 5, dextrad water route 6, left-hand water route 7, right water cavity 8, radiator water route 9, sealing ring 10, retaining post 11; Left water cavity 2 left end is provided with extra feed tank 1, left water cavity 2 right-hand member is connected with valve body 4 left end, valve body 4 right-hand member is connected with right water cavity 8 left end, right water cavity 8 right-hand member is connected with radiator 9, and in left water cavity 2, left side and the interior right side of right water cavity 8 are respectively provided with 2 retaining posts 11, are provided with spool 5 in valve body 4, valve body 4 and spool 5 are combined closely by sealing ring, be provided with spring 3 in left water cavity 2, spring 3 two ends are connected with spool 5 left end with on the left of left water cavity 2 respectively, are provided with dextrad water route 6, left-hand water route 7 in spool 5.
With reference to figure 1, Fig. 2 and Fig. 3, control method for the parallel pipe pressure balance valve of internal combustion engine extra feed tank is: when in extra feed tank 1, the pressure of cooling fluid is greater than radiator 9, can produce dextrad thrust makes spool 5 move to the right, until the left-hand tension balanced that the dextrad thrust produced by pressure difference and spring 3 deformation produce, spool 5 stop motion, valve body 4 is exposed in dextrad water route 6, on the left of spool 5, the extra feed tank cooling fluid of left water cavity 2 flows to right water cavity 8 on the right side of spool 5 by dextrad water route 6, spool two ends pressure difference reduces gradually, the dextrad thrust produced reduces thereupon, spool 5 is retracted initial position by spring 3, valve two ends cooling fluid stops exchanging, when in radiator 9, the pressure of cooling fluid is greater than extra feed tank 1, can produce left-hand thrust makes spool 5 move to the left, until the dextrad thrust-balancing that the left-hand thrust produced by pressure difference and spring 3 deformation produce, spool 5 stop motion, valve body 4 is exposed in left-hand water route 7, on the right side of spool 5, the radiator coolant of right water cavity 8 flows to left water cavity 2 on the left of spool 5 by left-hand water route 7, spool 5 two ends pressure difference reduces gradually, the left-hand thrust produced reduces thereupon, spool 5 is pushed back initial position by spring 3, valve two ends cooling fluid stops exchanging, when actual pressure difference is less than minimum pressure difference limen value a, the lateral thrust produced is not enough to make the displacement of the horizontal side-to-side movement of spool 5 exceed dextrad water route 6, left-hand water route 7 and spool 5 two ends institute made allowance, then valve two ends cooling fluid does not exchange, when actual pressure difference is greater than maximum pressure difference limen value b, the lateral thrust produced makes the displacement of the horizontal side-to-side movement of spool 5 reach maximum, peak at retaining post 11, valve body 4 is all exposed in dextrad water route 6 or left-hand water route 7, and valve two ends cooling fluid exchange capacity reaches peak value.
Replaceable existing extra feed tank valve when parallel pipe pressure balance valve is on automobile, and flexible pipe can be used to connect, also little compared with former extra feed tank valve to space requirement, and provide pressure in more stable, reliable radiator water route to regulate.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
