Abstract
A tank cover of a liquid storage tank comprises a seal ring, a venting base, a rubber ring and a cover body, wherein the seal ring is sleeved in a clamping groove of the venting base in inlaid mode, the venting base is provided with a bottom plate, a first round wall and a second round wall, and the first round wall and the second round wall are vertical to the bottom plate. The diameter of the second round wall is larger than that of the first round wall, and the rubber ring is clamped between the second round wall and the cover body. The rubber ring is provided with a tongue portion which is extended to abut against the first round wall, and accordingly the first round wall, the second round wall, the tongue portion and the bottom plate are formed into a cavity. The bottom plate of the cavity is provided with a venting hole, and the middle of the cover body is provided with an air inlet. When the pressure in the liquid storage tank equals or is larger than the external pressure, the tank cover can retain the sealing performance of the liquid storage tank excellently. When the liquid level in the liquid storage tank is lowered and accordingly the internal air pressure is reduced, the external air can be led into the tank to keep balance between the internal air pressure of a tank body and the external air pressure.
Description
Technical field
The utility model relates to a kind of cover that is used for receiver on the automobile, more specifically to a kind of cover that is used for the receiver of car engine cooling system and brake system.
Background technology
Car engine cooling system and brake system need receiver usually, and it links to each other with radiator by flexible pipe, and the refrigerant fluid that overflows when being used to collect temperature build-up in cooling system keeps suitable refrigerant fluid height.Along with the cooling and the contraction of refrigerant fluid, it is sucked radiator by vacuum again.Thereby need provide a kind of receiver leak tightness that can guarantee when the jar internal pressure reduces, to guarantee receiver jar internal pressure and the roughly cooresponding cover of external pressure again.
The utility model content
The purpose of this utility model provides a kind of receiver cover, makes receiver can guarantee leak tightness, can guarantee that when the jar internal pressure reduces receiver jar internal pressure is roughly suitable with external pressure again.
The purpose of this utility model can take following method to realize:
A kind of receiver 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 is provided with 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 air extractor vent, the middle part of described lid is provided with admission port.
Preferably, described seal ring is the O RunddichtringO.
Preferably, described lid is provided with the claw that combines with receiver jar mouth.
Wherein, cover is with after tank body cooperates, be sealed and matched by O wall rubber ring and tank body oral area, when causing air pressure inside to reduce when the inner liquid level decline of receiver, extraneous gas can feed (admission port place rubber ring and lid are 4 contact matching, and elsewhere can be ventilated) from admission port, and gas is opened cooperating of rubber ring tongue and first circular wall then, flow in the receiver by air extractor vent then, to keep tank interior air pressure and external balance.
Because the utility model has adopted above-mentioned technical measures, make its contrast prior art that following advantage be arranged:
When the receiver internal pressure is equal to or greater than external pressure, cover can keep the leak tightness of receiver well, when causing air pressure inside to reduce, extraneous gas can be introduced in the jar with maintenance tank interior air pressure and external balance when the inner liquid level decline of receiver.
Description of drawings
Fig. 1 is the topology view of the utility model receiver cover.
The specific embodiment
Describe implementation of the present utility model in detail below in conjunction with embodiment.
Referring to Fig. 1, the receiver 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 is provided with 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 air extractor vent 5, the middle part of lid 4 is provided with admission port 6.
In addition, lid 4 also is provided with the claw that combines with receiver jar mouth (not shown).
When causing air pressure inside to reduce when the inner liquid level decline of receiver, extraneous gas can (admission port 6 place's rubber rings and lid be 4 contact matching from admission port 6 feedings, elsewhere can be ventilated), gas is opened the tongue 7 of rubber ring 3 and cooperating of first circular wall 9 then, flow in the receiver by air extractor vent 5 then, to keep tank interior air pressure and external balance.
Claims (1)
1. receiver cover, comprise the O RunddichtringO, the ventilation seat, rubber ring and lid, it is characterized in that: described O RunddichtringO 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 is provided with 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 air extractor vent, the middle part of described lid is provided with admission port, and described lid also is provided with the claw that combines with receiver jar mouth.
