Abstract
The invention relates to a tank cover of a liquid storage tank, which comprises a sealing ring, a ventilating seat, a rubber ring and a cover body, wherein the sealing ring is nested in a blocking groove of the ventilating seat; the ventilating seat is provided with a baseplate and a first circular wall and a second circular wall which are vertical to the baseplate; the diameter of the second circular wall is larger than that of the first circular wall; the rubber ring is blocked between the second circular wall and the cover body and is provided with a tongue part; the tongue part is leaned against the first circular wall in an extending way, thereby the first circular wall, the second circular wall, the tongue part and the baseplate form a cavity; air vents are arranged on the baseplate for forming the cavity; and an air inlet is arranged in the middle of the cover body. When the internal pressure of the liquid storage tank is equal to or larger than the external pressure, the tank cover can well preserve the sealing property of the liquid storage tank; and when the reduction of the internal liquid level of the liquid storage tank leads to the reduction of the internal pressure, the tank cover can lead external air to the interior of the tank so as to keep the internal pressure and external pressure of the tank body balance. In addition, the liquid storage tank is designed in a split way and are arranged by using parts in the tank.
Description
Technical field
The present invention relates to a kind of cover for liquid storage tank on the automobile and liquid storage tank, more specifically to a kind of cover of the liquid storage tank for car engine cooling system and braking system and the liquid storage tank that seals with this cover.
Background technique
Car engine cooling system and braking system need liquid storage tank usually, and it links to each other with radiator by flexible pipe, are used for collecting the cooling liquid of overflowing when temperature raises in cooling system, keep suitable cooling liquid height.Along with cooling and the contraction of cooling liquid, it is sucked radiator by vacuum again.Thereby need provide a kind of liquid storage tank sealing that can guarantee when the jar internal pressure reduces, to guarantee roughly suitable cover of liquid storage tank jar internal pressure and external pressure again.In addition, existing liquid storage tank is whole the manufacturing, adopts blow moulded polyethyene to form, and is unfavorable for installing in jar part.
Summary of the invention
The liquid storage tank that the purpose of this invention is to provide a kind of liquid storage tank cover and seal with this cover, make liquid storage tank can guarantee sealing, can guarantee that when the jar internal pressure reduces liquid storage tank jar internal pressure is roughly suitable with external pressure again, be convenient to the installation of part in the liquid storage tank simultaneously.
Purpose of the present invention can take following method to realize:
A kind of liquid storage tank cover, comprise seal ring, the ventilation seat, rubber ring and lid, described seal ring is nested in the draw-in groove of described ventilation seat, first circular wall and second circular wall that described ventilation seat has base plate and arranges perpendicular to described base plate, the diameter of described second circular wall is greater than the diameter of described first circular wall, described rubber ring is fastened between described second circular wall and the described lid, described rubber ring has tongue, described tongue is resisted against on described first circular wall with extending, thereby described first circular wall, described second circular wall, described tongue and described base plate constitute a chamber, constitute on the base plate in described chamber and offer vent, the middle part of described lid is provided with suction port.
Preferably, described seal ring is the O RunddichtringO.
Preferably, described lid is provided with the claw of being combined with liquid storage tank jar mouth.
A kind of liquid storage tank that adopts this liquid storage tank cover to seal, described liquid storage tank comprises the tank body that is made of upper tank body and lower tank, described upper tank body top is provided with a jar mouth, described liquid storage tank cover is equipped with a jar mouth, described jar mouthful of place also is provided with filter screen, described tank interior is provided with float, and described lower tank bottom is provided with the liquid level early warning sensor, and described liquid level early warning sensor is arranged on the below of described float.
Preferably, described tank body is provided with tag line.
Wherein, cover is with after tank body cooperates, be sealed and matched by O type rubber ring and tank body oral area, when causing air pressure inside to reduce when the inner liquid level decline of liquid storage tank, extraneous gas can feed (suction port place rubber ring is at 4 with lid and contacts cooperation can to ventilate in other places) from suction port, and gas is opened cooperating of rubber ring tongue and first circular wall then, flowed in the liquid storage tank by vent then, to keep tank interior air pressure and external balance.
Because the present invention has adopted above-mentioned technical measures, make its contrast prior art that following advantage be arranged:
When the liquid storage tank internal pressure is equal to or greater than external pressure, cover can keep the sealing of liquid storage tank well, when causing air pressure inside to reduce when the inner liquid level decline of liquid storage tank, extraneous gas can be introduced in the jar with maintenance tank interior air pressure and external balance.In addition, liquid storage tank has adopted split type setting, is beneficial to the installation of jar interior part.
Description of drawings
Fig. 1 is the topology view of liquid storage tank cover of the present invention;
Fig. 2 is the view that liquid storage tank cover of the present invention cooperates with liquid storage tank.
Embodiment
Describe implementation of the present invention in detail below in conjunction with embodiment.
Referring to Fig. 1, the liquid storage tank cover comprises O RunddichtringO 1, ventilation seat 2, rubber ring 3 and lid 4, O RunddichtringO 1 is nested in the draw-in groove of ventilation seat 2, first circular wall 9 and second circular wall 10 that ventilation seat 2 has base plate and arranges perpendicular to base plate, rubber ring 3 is fastened between second circular wall 10 and the lid 4, rubber ring 3 has tongue 7, tongue 7 is resisted against on first circular wall 9 with extending, thereby first circular wall 9, second circular wall 10, tongue 7 and base plate constitute a chamber, constitute on the base plate in described chamber and offer vent 5, the middle part of lid 4 is provided with suction port 6.
In addition, lid 4 also is provided with the claw of being combined with liquid storage tank jar mouth (not shown).
When causing air pressure inside to reduce when the inner liquid level decline of liquid storage tank, extraneous gas can (suction port 6 place's rubber rings be at 4 with lid and contact cooperation from suction port 6 feedings, can ventilate in other places), gas is opened the tongue 7 of rubber ring 3 and cooperating of first circular wall 9 then, flowed in the liquid storage tank by vent 5 then, to keep tank interior air pressure and external balance.
Referring to Fig. 2, liquid storage tank comprises the tank body that is made of upper tank body 11 and lower tank 12, upper tank body 11 tops are provided with a jar mouth 13, the liquid storage tank cover is equipped with a jar mouth 13, jar mouthful 13 places also are provided with filter screen 15, and tank interior is provided with float 14, and lower tank 12 bottoms are provided with liquid level early warning sensor 16, and liquid level early warning sensor 16 is arranged on the below of float 14, cooperates with float the liquid level in the liquid storage tank is detected early warning.
