Abstract
The utility model discloses a radiator expansion water tank cover, which comprises a pedestal and a water tank cover, wherein, the pedestal is inversely buckled in the water tank cover; a big sealing ring is pressed on the cap edge of the pedestal, and the pedestal is fixed together with the water tank cover by the big sealing ring; a movable block is arranged in a cavity of the pedestal, and can move up and down between the pedestal and the water tank cover; one side on the cap cover of the movable block is provided with a small sealing ring, and the side is faced to the pedestal; a big spring is arranged between the cap edge of the movable block and the water tank cover; a cylinder sealing post is arranged in the cavity of the movable block, which can move up and down and the bottom is provided with a rim; a small spring is arranged between the rim of the sealing post and the pedestal; axes of the pedestal and the movable block are provided with vent holes; the axes of the sealing post is provided with a vent microscopic hole; the bottom of the pedestal and the inner wall of the water tank cover are provided with passages communicated with the exterior. The radiator expansion water tank cover reduces the structure of water-cooling system of an engine of an autobike, and reduces parts and cost. Meanwhile, the structure of the radiator expansion water tank cover is different from other vehicle radiator covers.
Description
Technical field
The utility model relates to the radiator swelling water case lid of a kind of motor, particularly a kind of water cooled engine.
Background technique
The application of water cooled engine on motorcycle is more and more.The critical piece of water cooling system has radiator, fan, water pump, thermostat and water-cooling tube.Automatic compensation heat dispersion device characteristics are to have set up expansion tank: after cooling water expands, in the radiator more than water flow into expansion tank; After temperature reduces, produced certain degree of vacuum in the radiator, the sucked back again radiator of the water in the expansion tank.Therefore can avoid the loss of cooling water, but the valve of steam need be installed on swelling water tank.
Summary of the invention
Goal of the invention: it is simpler that the purpose of this utility model provides a kind of structure, has the radiator swelling water case lid of automatic valve.
Technological scheme: radiator swelling water case lid described in the utility model comprises pedestal and tank lid; The pedestal of cylindrical cap shape tips upside down in the tank lid, and big sealing ring is pressed on the shade of pedestal pedestal and tank lid are fixed together; The movable block of cylindrical cap shape places in the cavity of pedestal, and can move up and down between pedestal and tank lid, and the side towards pedestal on the shade of movable block is equipped with small sealing ring, is provided with big spring between the shade of movable block and tank lid; In the cavity of movable block, there is a bottom that can move up and down to have cylindrical seal post, between limit and pedestal, is provided with little spring in sealing column along the limit; Axle center at pedestal and movable block is provided with vent, is provided with ventilating microhole in the axle center of sealing column, is provided with passage with exterior at the inwall of the bottom of pedestal and tank lid.
Working principle of the present utility model is: when the vapor pressure in the swelling water tank was higher than the numerical value of setting, the pressure that steam overcomes big spring promoted to move on the movable block, thereby got through the passage of steam row to air, shown in Fig. 1 hollow arrow.When the vapor pressure in the swelling water tank during less than certain numerical value, the pressure that the vent of air outside by the movable block bottom overcomes little spring promotes sealing column and moves down, thereby gets through the passage that air outside enters swelling water tank, shown in Fig. 2 hollow arrow.Under the normal condition, big spring withstands movable block and is close to pedestal, and little spring withstands the through hole sealing that sealing column makes the movable block top, and the micropore of sealing column guarantees to be in the fine setting state between swelling water tank and the atmosphere.
Beneficial effect: the utility model covers the pressure controlled valve of radiator and expansion tank and is integral, and has simplified the structure of motorcycle engine constituent, has reduced part, has reduced cost.Simultaneously, structurally be different from other car radiator lid.
Description of drawings
Fig. 1 when distributing steam, the gas flow structural representation.
Fig. 2 is when drawing atmosphere, the gas flow structural representation.
Embodiment
As shown in the figure, radiator swelling water case lid described in the utility model comprises cylindrical cap shape pedestal 1, little spring 2, small sealing ring 3, cylindrical cap shape movable block 4, sealing column 5, big spring 6, big sealing ring 7 and tank lid 8.Wherein tank lid is screwed in the oral area of swelling water tank 9.At ordinary times, cooling system does not communicate with atmosphere.When the pressure in the cooling system was higher than rating value, steam overcame the pressure of big spring 6, and small sealing ring 3 breaks away from pedestal 1, and valve is opened automatically, and a part of steam is revealed by the export mouth of tank lid, thus the pressure in the control swelling water tank.When the pressure in the cooling system was lower than the external atmospheric pressure certain value because of water vapour solidifies, air overcame the pressure of little spring 2, and sealing column 5 is separated with movable block 4, increased air inflow; Simultaneously, because the swelling water tank internal pressure is little, the pressure of little spring 2 reduces, and movable block 4 separates with sealing column 5, produces the gap, and swelling water tank is communicated with atmosphere, carries out tonifying Qi and avoids forming in water pipe and the radiator vacuum.
