Fig. 2 is the deformation state figure under spring and gas pressure effect of the seal ring among Fig. 1.
The detailed description of specific embodiment
See also Fig. 1 and Fig. 2, storage hydrogen bottle structure with top-opening type valve of the present utility model comprises storage hydrogen bottle 1 and top-opening type valve, wherein, storage hydrogen bottle 1 is provided with stepped bore on the inwall of mouth cylindrical part, the diameter in the last hole 11 of this stepped bore then is provided with outside thread greater than the diameter in following hole 12 on the outer wall of storage hydrogen bottle 1.The top-opening type valve comprises:
One valve body 2, a filter 3, a pad 4, a push rod 5, a seal ring 6, two catch 7, spring 8, wherein, valve body 2 can be made into the cap shape, be provided with big and first and second logical endoporus 21,22 that are connected with each other of ratio of two diameters thereon between the lower end wall, in second endoporus 22, be provided with internal thread, and in first endoporus 21 and second, be provided with a diameter between 22 holes greater than first endoporus with less than the pit 23 of second endoporus.Valve body 2 can be screwed in by the internal thread in second endoporus 22 outside the described storage hydrogen bottle mouth cylindrical part;
Filter 3 is cup-shapeds, also can be the stereo structure disk of other shape or plane plectane, and wherein, the filter of cup-shaped is made up of the convex shoulder 32 that inner cup portion 31 and its oral area extend radially outwardly.Generally, filter is to be formed by copper or stainless steel sintering, wherein contains the micropore of equally distributed diameter below 3 μ m, so that can see through more hydrogen, can not see through hydrogeneous powder.That is to say that because the distribution area of micropore relation, the filter 3 permeable hydrogen of cup-shaped are more, suiting provides more hydrogen supply amount, and the hydrogen that plane plectane sees through is less, and suitable supply needs the device of small quantity of hydrogen.In the present embodiment, filter 2 adopts cup-shaped, and it is installed in the stepped bore of storing up the hydrogen bottle and is suspended at by convex shoulder 32 on the stage of stepped bore.
Pad 4 is ring parts, and it is installed in the last hole 11 of stepped bore of storage hydrogen bottle 1 and covers on the oral area of filter 3.In addition, its annular distance or intermediate hole 41 can provide the hydrogen that passes filter to flow to the passage in the last hole of the stepped bore of storing up the hydrogen bottle.
Push rod 5 is one to have the straight-bar of intermediate groove 51, and is that the boundary is divided into upper and lower bar portion with the groove.It is installed in the stepped bore of storage hydrogen bottle, and makes upper pole part extend to the aperture of first endoporus 21 of valve body 2, and the diameter of lower beam portion is greater than the aperture of the center hole of pad, so its lower end is to be resisted against on the pad 4 in free state.In a preferred embodiment, in the maximum lifting position of push rod 5, its upper-end surface does not exceed the upper-end surface of valve body 1, and just, the free end of the upper pole part of push rod 5 position in off position is to flush with the upper-end surface of valve body 1.In addition, to form relative gap between them, making can outwards provide hydrogen by the gap to the diameter of the upper pole part of push rod 5 when the top-opening type valve open less than the aperture of first mounting hole 11 of valve body.
Seal ring 6 is O-ring seals, be installed in the groove 51 of push rod, and its external diameter is equal to or less than the last hole internal diameter of described storage hydrogen bottle bottle 1 oral area, so that can make the hydrogen in the storage hydrogen bottle can be by the outer ring surface current mistake of seal ring 6 when the top-opening type valve open.
Two catch 7 are identical with holes, and each catch external diameter is less than or equal to the external diameter of seal ring 6, they be nested with in push rod and be positioned at above the seal ring 6 and below.In a preferred embodiment, described two catch 7 ' (not drawing among the figure) is that the perisporium of described push rod in groove 51 both sides radially extends integrally formed.
Spring 8 is the spiral compression springs that reset, it is enclosed within the lower beam portion of push rod and is arranged in the last hole 11 of the stepped bore of storage hydrogen bottle, its end is resisted against on the following catch 7, the other end is resisted against on the pad 4, and make catch 7 above the push rod and seal ring 6 under spring promotes, enter in the pit 14 of valve body together and make seal ring 7 be squeezed distortion to constitute to the sealing between first endoporus 21 of hole 11 and valve body 2 on the storage hydrogen bottle 1, as shown in Figure 2.
Top-opening type valve and the bottled time-out that fits over of storage hydrogen also can be provided with the structure that is tightly connected that seal washer constitutes the reinforcement between valve and the storage hydrogen bottle between the bottleneck end by inner step between first and second endoporus of valve body and described storage hydrogen bottle.
The basic functional principle of valve,
Because valve body 2 centers of top-opening type valve of the present utility model have one along axial transportable push rod 5, the middle part of push rod has a groove 51 can place an O-ring seals that seals 6, there are two rounded tabs 7 at the two ends of seal ring, in order to as making O-ring seals must make the block of axial displacement with push rod 5, so the upper end of one of rounded tabs 7 also is the axial limiting that push rod moves up.The lower end of another of rounded tabs 7 then is the supporting point of Returnning spring 8.Under the effect of initial tension of spring, push rod is resetted, the pressure that also is subjected to simultaneously internal hydrogen in actual use makes the O-ring seals distortion, cause its outer ring to contact with the tight of groove 51 of push rod 5 with pit 23, the inner ring of valve body, play pre-sealed effect, with the blocking-up of the circulation between the last hole 11 of first endoporus of valve body 2 and Chu Qing bottle 1 or close, to stop the outside outflow of gas in the bottle.
Please consult Fig. 2 again, the closing of storage hydrogen bottle structure valve with top-opening type valve of the present utility model is lean on O-ring seals 6 pre-sealed.Its principle is that the pretightening force of spring 8 forces the O-ring seals distortion on push rod 5, thereby realizes the effect of valve closing.When force pushing mandril 5 moves down outside, O-ring seals 6 is moved down break away from valve body pit 23, thereby sealing is removed, reach the effect of valve opening, so that hydrogen outwards to be provided.
During valve opening, its air feed runner be by push rod 5 and valve body 2 first in gap between 21 constitute, so flow can be very not big.For this this valve is applicable to the hydrogen storage cylinder that stores alloy material for hydrogen is housed in the bottle, is particularly useful for small-sized and miniature hydrogen storage cylinder, because hydrogen bearing alloy becomes ruthless trickle granular after the activation of storage hydrogen.
For preventing that these molecules from taking out of with gas, this valve must be equipped with filter 3 with prevent more than the 3 μ m particle take out of.For the flow that guarantees gas output satisfies usage requirement, so the design's filter is circlewise, wherein contain the micropore of the following similar spongelike structure of 3 μ m, can under less diameter dimension, obtain bigger filter area, thereby guarantee output flow.But, when the flow that requires allows, also can be flat circle.
In one embodiment, valve also comprises the insertion quick open type, can directly insert storage hydrogen bottle.
