Abstract
The utility model relates to an automobile water tank cover structure, in particular to an expansion tank pressure relief cover structure, which comprises a large cover and a sealing ring. The expansion tank pressure relief cover structure is characterized in that an inner cover fastened with the large cover is arranged in the larger cover, and a pressure regulating structure is arranged in the space formed by mutually fastening the inner cover with the large cover. The expansion tank pressure relief cover structure has the advantages that the structure is simple and compact and is easy to assemble, internal air pressure and external air pressure are balanced by an effective pressure relief mechanism on an expansion tank when the temperature of an engine is excessively high or low so as to affect normal functions of an automobile, the pressure relief mechanism is automatically opened when the internal circulating pressure of an engine cooling system is higher than specified pressure, and stable air pressure is achieved by the aid of internal and external circulation, so that the engine runs normally and effectively. When liquid in a radiator or the engine is decreased, liquid in the expansion tank is compensated to the engine or the radiator through a water outlet hole so as to supplement the decreased liquid, and the normal functions of the engine are achieved.
Description
Technical field
The utility model relates to a kind of radiator cover structure, is a kind of swelling water tank pressure release lid structure specifically.
Background technique
At present automobile swelling water tank pressure release effect is bad and case internal pressure that cause is excessive or too small and cause that exhaust, discharge opeing are bad, thereby causes engine temperature too high or too low, can't satisfy its normal function of use.
Summary of the invention
In order to remedy the deficiencies in the prior art, the utility model provides a kind of swelling water tank pressure release lid structure that can make motor not influence the normal use of motor car engine when too high or too low for temperature that has.
The utility model is achieved by the following technical solution:
A kind of swelling water tank pressure release lid structure comprises big lid and seal ring, and its special way is: be provided with the inner cap with its fastening in the described big lid, be provided with pressure adjustmenting mechanism in the space that inner cap and big lid fasten mutually.
Swelling water tank pressure release lid structure of the present utility model, on the basis of existing big lid, be provided with the inner cap with its fastening, in the space that inner cap and big lid fasten mutually, be provided with pressure adjustmenting mechanism, pass through pressure adjustmenting mechanism, air pressure in the regulating tank makes its proper functioning.
Can both proper functioning when too high or too low for temperature in order to enable water tank, described decompression mechanism is made up of positive stage clip between inner cap and the big lid and the inner cap gland that is connected on the positive stage clip, for guaranteeing the performance of decompression mechanism, good airproof performance is provided with sealing gasket and sealing support plate between described pressure release lid and the positive stage clip.
The beneficial effect of the utility model swelling water tank pressure release lid structure: have simple in structure, compact, easily assembling, can make motor too high or too low for temperature when influencing the normal function of use of automobile, by effective pressure relief on the swelling water tank, when engine-cooling system inner loop pressure during greater than authorized pressure, decompression mechanism is opened automatically, by interior outer circulation, it is steady to reach air pressure, thereby makes the normal effectively work of motor.When liquid in radiator or the motor reduced, the liquid in the swelling water tank compensated to motor or radiator by osculum, to replenish the liquid that reduces, satisfied the normal function of use of motor.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a sectional view of the present utility model;
Among the figure, 1, Da Gai, 2, positive stage clip, 3, sealing gasket, 4, inner cap, 5, the negative pressure spring, 6, the pressure release lid, 7, the sealing support plate, 8, the inner cap gland, 9, seal ring.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises big lid 1 and seal ring 9, it is characterized in that: be provided with inner cap 4 in the described big lid 1 with its fastening, in inner cap 4 and the big lid 1 mutual space that fastens, be provided with pressure adjustmenting mechanism, described pressure adjustmenting mechanism is divided into decompression mechanism and booster body, described decompression mechanism is made up of positive stage clip 2 between inner cap 4 and the big lid 1 and the inner cap gland 8 that is connected on the positive stage clip 2, described booster body by the negative pressure spring 5 that is arranged on positive stage clip 2 the insides and be connected negative pressure spring 5 and positive stage clip 2 between pressure release lid 6 forms, be provided with sealing gasket 3 and sealing support plate 7 between described pressure release lid 6 and the positive stage clip 2.
Motor is in running, owing to raising, the inner loop system temperature cause pressure excessive, portion gas or liquid by exhaust the liquid pipe enter swelling water tank, the water tank internal pressure increases, when internal pressure greater than regulation during numerical value, gas or liquid are by inner cap 4, impact pressure release lid 6 and promote sealing gasket 3 and sealing support plate 7, promoting positive stage clip 2 again discharges gas or liquid with inner cap gland 8 by near the spill pipe the pressure release lid 6 on the large water tank, when engine temperature reduces or internal pressure when being reduced to regulation numerical value, negative pressure spring 5 is had an effect, and passes through decompression mechanism, reach inside and outside air pressure balance, thereby make the motor proper functioning.
