Abstract
The invention discloses a device installed in an elastomer in confined space, which aerates air for the confined space by deformation generated by repeated constant pressure and realizes constant pressure. The device is composed of a large air pump and a small air pump which are connected in series; the compression area of the small air pump is smaller than that of the large air pump; and in practical work process, the two air pumps work together or work alternatively, so as to realize the aeration of high-pressure air in the elastomer and stops charging air under a constant pressure. The final aeration air pressure can be regulated by regulating the starting air pressure of the single-way valve at the output end of the large air pump.
Description
Affiliated technical field
Passing through repeatedly of the present invention relates to install in a kind of elastomer in confined space distortion that constant pressure causes comes to the elastic space inflation and realizes the device of constant voltage.
Background technique
At present, known elastomer in confined space comprises: tire, ball, water wing etc., and its common inflation has several modes: 1, pump; 2, electric air pump; 3, mouth blows.About realize inflating the also technology of constant voltage automatically by built-in, retrieval finds that existing much formerly technology is open, specifically asks for an interview following contrast:
Documents 1: the patent No. is to disclose a kind of design proposal in 89211618.8 the Chinese patent literature, and its characteristics have: 1, described inflator is put in the tire; 2, emit body and an air pump to form by a described pump; 3, adopt one-level air pump structure; 4, inflate from being out of shape compressed pneumatic pump by tire;
Documents 2: the patent No. is to disclose a kind of design proposal in 90104185.8 the Chinese patent literature, and its characteristics have: 1, described inflator is put in the tire; 2, form by a described connecting rod and an air pump; 3, adopt one-level air pump structure; 4, inflate from distortion bump connecting rod compressed pneumatic pump by tire;
The described technology of above patent has three common ground to be exactly: 1, place tire inside; 2, adopt one-level air pump structure; 3, realize inflation by tire from distortion.But through discovering, in practical work process, above-described technology can not produce the specified highpressure of tire because the air pump distortion is limited, and also there is the metal bar linkage structure in documents 2 described technology and clashes in the course of the work, and itself and tire are very easily caused damage.
In a lot of similar patent of retrieval, finding after deliberation has a common ground: wherein adopt the design of one-level air pump in fact can only charge into minimum gas.Because what the one-level air pump sucked is standard atmosphere pressure, when tire distortion hour, the deformation compression that air pump produces is also very little, and therefore the air pressure in the air pump can not continue inflation much smaller than tyre pressure.Can not reach the specified air pressure of tire.More application is the connecting rod piston formula in addition, inflates by clashing into, and how can damage tire and charger itself.
Summary of the invention
In order to overcome prior art complex structure, processing cost height, disadvantages such as loaded down with trivial details and principle defective to be installed, the invention provides a kind of can produce pressurized gas, structure very simple, with low cost, be easy to realize, not easy to wear and can be inflated structure processing all-in-one-piece and inflate the also device of constant voltage automatically by distortion certainly.
The technical solution adopted for the present invention to solve the technical problems is: the present invention is made of two air pumps of size of series connection, stingy pump compression area is less than the atmospheric pump compression area, two air pumps or simultaneously or alternation in practical work process are to realize charging into pressurized gas toward elastomer in and constant voltage stops inflating.
The present invention adopts following special structure, has realized the function of high-pressure aerated and constant voltage:
1, little air pump is the extremely compact pressure-resistance structure in inner space, and when being compressed to the limit, internal capacity is near 0, and to realize producing the gas demand of high compression ratio, this also is one of key component of the present invention.According to pressure formula: P=F/S, the lifting surface area S1 of little air pump is according to designing less than F/P, F is suffered pressure maximum, P is the specified air pressure of elastomer, need only pressure F 〉=P*S1 like this, then can satisfy elastomeric specified air pressure requirement, and in actual applications, F is far longer than P*S1, for example the application in tire.
2, adopt two air pump cascaded structures, atmospheric pump can be realized storing pressurized gas, inflate and control the function that little air pump fills, stops to elastomer.The one-way valve (6) of adjusting atmospheric pump can be regulated inflation and stop air pressure.
For ease of understanding, can be similar to working procedure is regarded as: little air pump is inflated to elastomer to atmospheric pump inflation, atmospheric pump.Be inflated to certain moment, the atmospheric pump turgor, little air pump can not launch, atmospheric pump continues to inflate to elastomer under pressure, stingy immediately pump launches to continue to the atmospheric pump inflation, and the air pressure that produces under pressure up to atmospheric pump is not enough to open one-way valve, no longer inflates to elastomer.Atmospheric pump is in the turgor state, and little air pump again can not launch, and stops inflation.
2 explain its structure and working principle with reference to the accompanying drawings:
At first define running parameter: 1. P0 is a barometric pressure, and P1 is the air pressure of little air pump, and P2 is the air pressure of atmospheric pump, and P3 is elastomeric air pressure; 2. the unlatching air pressure of one-way valve (4) (5) (6) is respectively Pb1, Pb2, Pb3, and the unlatching air pressure of one-way valve is adjustable, and it is minimum that wherein Pb1, Pb2 open air pressure, can ignore in the calculating; 3. the area of stress surface (7) is S1, and the area of stress surface (8) is S2, applies constant force F repeatedly.
Suppose and start working under elastomeric natural swelling state, P1=P0, P2=P1, P3=P2 below is a working principle:
1, when elastomer is subjected to constant force F, be compressed, when elastomer air pressure hour, the compression that can produce big stroke.Because lifting surface area S1＜S2, P1＞P2 then, little air pump is inflated to atmospheric pump, and when P2＞P3+Pb3, atmospheric pump is inflated to elastomer.When inflation reaches balance, P3+Pb3=P2, P2=P1, P3＞P0, one-way valve (4) (5) (6) is closed.
2, when constant force F cancels, then elastomer recovers shape, and this moment is because the gas of atmospheric pump is pressed into elastomer, and therefore under the air pressure of P3 surrounds, atmospheric pump recovers a small amount of deformation makes P2=P3, and keeps confined state; Because the gas of little air pump is pressed into atmospheric pump, stingy pump will be unfolded under the pressure of P3, and when P1＜P0, one-way valve 4 is opened, and stingy pump sucks air.When reaching balance, P1=P0.P2＞P1, P3=P2, one- way valve 4,5,6 closed conditions.
3, circulation 1,2 processes.Expand up to atmospheric pump, little air pump is compressed to the limit, and this moment, constant force F acted on the stress surface 8 of atmospheric pump by the hard pump housing of little air pump, and atmospheric pump is compressed, and continues to inflate to elastomer.Lose stressed after, atmospheric pump is owing to exhausting air diminishes, little air pump is to a certain degree recovered once more.
4, circulation 1,2,3 processes.Along with the air pressure rising of P3, pressure F can only make elastomer produce slight deformation, and this moment, the gas of little air pump was pressed into atmospheric pump fully, atmospheric pump expand into the limit, slight deformation directly acts on atmospheric pump, if the pressure P2 of this moment≤during P3+Pb3, just can not inflate to elastomer again.When pressure was cancelled, elastomer, atmospheric pump recovered deformation simultaneously, and little air pump is no longer opened.This moment, P3 reached specified pressure.Under the effect repeatedly of constant force F, because little air pump can not launch, can not realize the process of inflating again, thereby reach the purpose of constant voltage.
When 5, gas replenishment process finished, elastomer continued to produce slight deformation under pressure F, but no longer continues inflation, and the deformation range of this permission can be set by the unlatching air pressure of regulating one-way valve (6).The unlatching air pressure of one-way valve (6) equals the maximum pressure that P2 increases in the slight deformation range that allows.
6, when owing to reason elastomer internal air pressure P3 such as chronic leakage or slight gas leakage＜P2-Pb3, atmospheric pump is inflated to elastomer once more, after pressure is cancelled, elastomer recovers deformation, atmospheric pump is compressed, little air pump opens air-breathing, enters the circulation of 1,2,3,4 processes once more, stops after being charged to specified pressure.
7, the inner gas pressure size becomes approximate linear in the size of pressure F and the elastomer, just in time meets the practical application request of tire etc., and along with the increase of load-carrying, the corresponding automatic raising of tire pressure can allow tire work under an optimal air pressure.
The present invention is not subjected to the qualification of the foregoing description; in technical scope of the present invention, can carry out various distortion; for example adopt air pump or other elements of different structure, shape and material or do pro forma change slightly and other products of making, all should belong to protection scope of the present invention.
The invention has the beneficial effects as follows: 1, structure is very simple, and is with low cost, realizes easily.2, realize the gas replenishment process of control fully automatically.3, under acting on repeatedly, constant pressure can remain constant air pressure.4, increase and increase air pressure automatically and keep new air pressure with pressure.5, can with practical application in conjunction with as a whole, together produce as parts, further reduce cost.6, there is not vulnerable part.7, can directly inflate with conventional method.
