Description
Technical field
The present invention relates to the control valve of liquid-container internal gas pressure, it is used for matching with the hole that is arranged on container top, during less than external pressure, allows gas to flow into container with the pressure of convenient internal tank.When matching with the hole of container, when the difference of container external and internal pressure arrived a predetermined threshold value, this valve also must allow gas inside to flow to external container.
According to the application of a recommendation, these valves can be used on the fuel tank of automobile, especially are connected with some check valves.
Background technique
No matter be the working state which kind of fuel tank is in almost: the oiling in the engine operation process, and under high temperature condition, stop to refuel ... or the like, fuel tank all produces a large amount of gasoline vapors.These steam are drawn towards a charcoal filter, and this filter is used for that being used in being integrated in automobile controlled under the instruction of computer of engine operation regularly this steam row to the engine charge header pipe then with described steam storage.
In addition, also need sometimes to allow steam circulate to container, especially in causing container, produce under some temperature conditions with respect to the negative pressure of external pressure from atmosphere.For example when gasoline still heat and automobile needs like this when sailing a cold temperature environment into.Therefore should limit the negative pressure in the container that causes owing to this cooling.
Now existed and especially described among the patent documentation WO 02/059512 under the applicant's name the control valve of some controlling liquid internal tank gas pressures.When the difference of container external and internal pressure arrives a predetermined threshold, allow the outside of gas flow container; And, allow the gas reverse flow when the internal pressure of container during less than external pressure.
As the valve of the theme of patent documentation WO 02/059512, its feature is that mainly it comprises a main body, the bottom of main body is configured to be used for closing the hole of container, it also has for example such weight, surpasses the described pressure difference that constitutes predetermined threshold, and main body is left the hole.This main body also comprises the cavity that runs through of an extension part that is arranged on container hole, and this moment, both contacted, assembling on the circumference of described cavity one the difference of container pressure and external pressure on the occasion of the time obstruction ball that is activated.
This simple structure based on dual force mechanisms can obtain a kind of pressure rule, that is: when container was in negative pressure, fluid freely flowed into from the outside; And when pressure equated, passage was blocked; Then, when this container surpasses a predetermined overpressure value, fluid flows to outside from container.
Yet, also so only when being vertically oriented, can correctly work as this valve of patent documentation WO 02/059512 theme based on dual force mechanisms.
Under patent documentation WO 02/059512 residing working hypothesis situation, this valve exceeds the upper wall of container, thereby on vertical size, just on the direction of car floor, occupied the space that can not be ignored of this container, especially when this valve integrates with the check valve that is welded in the container upper wall, all the more so.
Be arranged under the situation of internal tank at described check valve and pressure controlled valve, described check valve need be positioned at certainly the container upper wall near; And, for vertical orientated described control valve being connected the there, need be by means of a syphon tube, but syphon tube will abandon certainly, because the delay of liquid fuel in the syphon tube bottom hindered the normal circulation of fuel vapour.
Summary of the invention
The present invention is intended to remedy these deficiencies, has proposed a kind ofly no matter to be in the technological scheme which kind of orientation the time can both be worked at this valve.
This innovative construction that for example can flatly use can overcome vertical direction excessive bulk in the existing scheme and promptly delete excessive bulk in traditional system of the external stability of container.In a kind of scenario that is integrated in internal tank, this scheme can avoid using syphon tube.
In order to realize these and some other purpose that hereinafter will sets forth in detail, the valve that matches with at least one hole that is opened in container top of the present invention also comprises a main body, main body is provided with the cavity that runs through that is connected with described hole, and has disposed the blockage element that starts when pressure in container is higher than external container pressure.Described main body can move under the inside and outside differential pressure of the container differential pressure action during greater than a predetermined threshold, and this moving can make the gas flow outside.Described main body is under this differential pressure action, in housing cavity volume with two openings that communicate with outside and container respectively, between the primary importance and the second place, slide, seat on this primary importance and the internal orifice that is arranged on the opening that links to each other with container contacts, and the gas flow outside has been blocked in this position; The described second place and seat allow above-mentioned flowing separately.Also be provided with some reset components, contact with seat so that promote main body.These reset components are calibrated, to guarantee described contact, till the threshold value that reaches pressure reduction.
In this scheme, the calibration of reset components has determined to make the internal over pressure threshold values of opening of valves, and is not decided by the weight of valve body like that in the prior art for another example.Because weight that in addition can minimized valve body no longer has decisive influence to working pressure, so the function of valve also just no longer is sensitive to the orientation of valve.
Patent documentation US 6 196 258 and FR 2 577 903 disclose some valves according to above-mentioned principle work.The main body of sliding also is provided with some obstruction piece that are used to run through the cavity of main body, some by with these parts that run through the contacted second return unit control of a bearing of cavity, they introduce sign and the aforementioned second opposite threshold pressure differential.
Technological scheme of the present invention does not require controls two return units simultaneously, but has proposed a kind of simple and practical scheme, wherein, does not have return unit ground control obstruction piece in closed position, in case the pressure in the container surpasses extraneous pressure, just occupies this closed position.
Like this, the described obstruction piece that is arranged in valve body be by one lightweight, constituted with the movable component of radial clearance in the part free shift that runs through cavity, this movable component can move into place on the interior seat of return unit one side in described part on the one hand, runs through cavity to block this; Be movable on the other hand on the stop member that is positioned at opening one side of leading to container, this movable component contacts with this stop member and does not carry out blocking.
Therefore this internal blocking spare is not subjected to the effect of return unit, so it only works under the simple effect of container and outside pressure reduction, and this pressure reduction has produced the pressure that is enough to obstruction piece is moved and fallen in cavity.The weight of obstruction piece is preferably very light, thereby weight no longer is the major parameter of internal valve work.
Mechanism of the present invention is actually works at twice.When the pressure difference between container and the outside become on the occasion of the time, act on active force on the main body and be not large enough to and make main body leave the opening that communicates with container.But this active force still is enough to produce some conditions to be made it possible to push moving part to interior seat, and therefore blocks the cavity that is arranged in the main body, thereby no longer includes gas exchange.
In case surpass a certain threshold pressure differential, the active force that acts on the valve body of the present invention is enough to it is pushed away vessel port, thereby fluid can free-flow.
The part that moves freely in the valve body preferably is made of a spheroid that can move in running through the cylindrical part of cavity.
According to a kind of possible situation, this spheroid is made at the plastics of compatibility aspect chemistry and the calorifics with fuel by a kind of, acetal resin for example, this material can ideally satisfy the pressure difference between container and the outside reach on the occasion of the time, to the desired performance of this spheroid.
More particularly, valve body of the present invention is columniform, and the end of its container one side is a hemisphere substantially, run through cavity be opened in described main body axially in.
For the reason of some manufacture view, the stop member that spheroid will contact is realized by an independent component that is fixed on the valve body with sealing means.
According to a kind of possible situation, this stop member firmly is inlaid in the main body, and the tolerance that it had has caused sufficient sealing.
The guiding of spheroid in body cavity needs highly stable size certainly, selects the material of main body with this.Main body, and the end member that relates to stop member are preferably made by molded plastics, and described in addition plastics are selected as making its size not to be subjected to influence from the possible chemical corrosion of the steam of container and/or liquid.
In patent documentation WO 02/059512, owing to need valve body to have certain weight, thereby make with steel; And can use plastics now, because weight role-taking in fact no longer.This has constituted attendant advantages that the present invention has Economy.
According to the present invention, return unit preferably is made of the spiral compression spring that is arranged in the cavity volume along the slip axis.
This spring is calibrated to desirable pressure, that is to say, has only when inner overvoltage has surpassed predetermined threshold, just allows the main body of valve to move.
Main body comprises a radially convex shoulder on its outer circumferential face, the end in the end of spring is as stop member, and the other end of spring is resisted against on the wall of housing.This convex shoulder can be annular, and perhaps the end by elements such as some radial ribs is constituted.
According to a kind of possible situation, housing is made of two-part of sealing means assembling, and each part comprises one in the opening of fluid passage.These two can assembled components, when they are in free state, has constituted a kind of configuration of sleeve pipe form, and this sleeve pipe can be inserted into and connect in container and the extraneous hydraulic pipe line.
Perhaps, this housing parts that has an opening that communicates with container also can be the solid memder that a loam cake with check valve is made one.
As what it will be appreciated that in the following description, these possibilities, together with the complete degrees of freedom on the orientation of valve that new structure gave, enable to be applied to easily multiple configuration, in particular for this single valve is attached in the system of a plurality of check valves, this can cause volume to reduce.
Description of drawings
Referring now to accompanying drawing the present invention is described in more detail, wherein:
Fig. 1 is the sectional view of the internal tank gas pressure control valve of a kind of sleeve pipe configuration of the present invention;
Fig. 2 has represented that this valve is attached to the sectional view on the check valve;
Fig. 3 a-3c has represented the different phase of the working procedure of valve of the present invention with the form in cross section;
Fig. 4 has represented the application scenarios of valve and two check valves arranged side by side of this sleeve pipe configuration;
Fig. 5 has represented the configuration with Fig. 4 equivalence, and this valve is attached in one of them check valve.
Embodiment
Referring to Fig. 1, the control valve C of control internal tank gas pressure of the present invention mainly comprises for example main body 1 and an end member 2 of plastics, this end member in particular as dribbling body 3, the stop member of acetal resin preferably.
The cooperation of these three elements can obtain a kind of compact structure that axially runs through cavity or inner passage 4 that has, and can allow fluid to pass through under certain conditions.
Like this, when spheroid was in the position of Fig. 1, it contacted with stop member 5, because cavity 4 and spheroid 3 transverse dimension separately cause existing air flows, thereby allowed a radial clearance, and allowed fluid to pass through (referring to Fig. 3 a) around spheroid 3.
In other words, the external diameter that spheroid had moves the diameter of place cavity part 4 less than spheroid, thereby when there is pressure difference the both sides of valve C, produces a kind of working pressure that can make spheroid 3 move and fall.
In case spheroid 3 is pulled to the right side and contacts with seat 6, because the circumferential contact between spheroid 3 and the seat 6 causes the circulation of whole fluid to be stopped.
As the end member 2 of the stop member 5 of spheroid 3, himself contacts with the bearing 12 at opening 10 places of a part 11 that is opened in the housing that valve C packed into, and this end member is inlaid in the main body 1 of valve C with sealing means.Described housing is finished by the second portion 13 that is assembled in first portion 11 hermetically, and this assembly has formed a sleeve pipe 15 round cavity volume 22.
This second portion 13 is provided with opening 8, and its inner circumference has determined to be used for the supporting member of pressure spring 7, and spring acts on the main body 1 of valve C by the convex shoulder on the annular flange 14.
In this embodiment, the opening 8,10 of sleeve pipe 15 extends body 16,17, thereby for example is generally used for Fig. 4 and as shown in Figure 5 sleeve pipe 15 is inserted in the hydraulic pipe line.
Fig. 2 has represented that described valve C and a check valve V are combined as a whole, and the latter comprises that mainly one is vertically passed the fuel tank upper wall and fixes valve body 19 (referring to Fig. 4 and Fig. 5) on it, and comprises valve C is installed a cap in it exactly or covers 18.The main body 19 of check valve V also comprises a buoyancy aid 20, when the automobile accident topple or fuel tank in the pasta of can when making that buoyancy aid contacts with hole 21, this buoyancy aid can be blocked hole 21, and these are not because directly related with the subject matter of this specification thereby described in detail.
The main body 1 of valve C flatly is arranged in the axially movable cavity volume 22 of permission valve C that covers in 18, and the right part of valve body is subjected to round the restriction of the bearing 12 ' of opening 10, and opening 10 leads to hole 21.The spring 7 of controlling the slip of valve C is resisted against on the supporting base at internal orifice place of the body 16 that exceeds element 13, and element is connected and covers on 18 for 13 this moments.
Relevant valve C and guarantee that the further details table of position of housing of the guiding of this valve is shown among Fig. 3 a-3c.Fig. 3 a has represented the interior pressure P of container
ROVLess than external pressure P
AtmSituation.In other words, internal tank has produced negative pressure.In this case, spheroid 3 is bearing on the stop member 5 of end member 2 of valve C, and because spheroid 3 and spheroid move the radial clearance that exists between the cavity volume part 4 at place, causes some to come from outside gases and flow into.The flow direction of fluid arrow F, F ' expression.This flowing is possible, because in end member 2, some passages of offering perpendicular to stop member 5 can not be plugged all the time.
In situation shown in Fig. 3 b, the internal pressure P of container
ROVBecome and equal or a little more than external pressure P
AtmIn this case, the active force that acts on the spheroid 3 is pushed it the seat 6 of main body 1 to, especially because between the wall of cavity 4 and spheroid 3, cause pressure fall and produced a kind of suction spheroid 3.This active force deficiency is so that valve C leaves bearing 12, but any gas communication no longer can carry out, thereby gas flow is zero.In this case, pressure difference is less than the threshold value that is reached oppositely the time among Fig. 3 c.
In the situation of Fig. 3 c, act on the pressure difference P on the valve C
ROV-P
AtmBe enough to make it to leave bearing 12, and fluid can flow along the direction opposite with flow direction among Fig. 3 a, at this moment be that the inside from container flows to outside.Container is in gas in overpressure.Arrow F, the direction of F ' is opposite with direction among Fig. 3 a.
In Fig. 3 a and Fig. 3 b, the main body 1 of valve C is fixing in cavity volume.When the interior pressure holding of container is continuous when increasing, exists one and make valve C leave its bearing 12 and thereby make the gas can be through the threshold value of via hole 10 forward flow.This pressure depends on the calibration of spring 7 and the selection of bearing 12 sizes certainly.In this situation, some fins 23 that are distributed on the circumference have guaranteed valve C main body 1 axial guiding fully in its cavity volume 22, allow gas to pass through simultaneously.In addition, the left end of these fins 23 also is used as the supporting member of spring 7.
When the valve that is set up in parallel with some was worked, Fig. 4 and Fig. 5 had represented the application of valve C of the present invention, and this valve C can be with form Fig. 4 of sleeve pipe, perhaps to be incorporated into the form Fig. 5 in the check valve.
Identical on their structural entity, just the lid 18 of the check valve V on the left side changes to some extent, to adapt to any one configuration.
The base plate of automobile is located in check valve V, and near the lid 18,18 ' of V ', and the usage requirement of vertical valve C passes described base plate it is installed, and therefore by the valve C for container R horizontal arrangement, the spatial gain that provides is significantly, but also has simplified installation.
The plurality of advantages of valve C of the present invention described above, yet be understood that according to top detailed description: it is little and simply implement by three simple mechanisms that make elements of a kind of needs that this technological scheme has reached volume, this mechanism can vertically be installed in the check valve of prior art or be such as shown here, flatly combines with in these check valves at least one or also can be that needs according to hydraulic pipe line adopt any direction.
Above-mentioned technological scheme does not certainly just for example mean that restriction the present invention, and it has been contained those skilled in the art and understands the shapes all in the scope and the modification of structure aspect.
