Now exemplify preferred embodiment of the present invention, and conjunction with figs. is described in further detail as follows.

At first see also Fig. 1 to Fig. 4, the disclosed leak resistance set of pipeline 10 of the present invention consists predominantly of: a body 20 can be passed through by its inside for gas; One closed component 30 is located at this body 20 inside, with when body is shaken in order to the blocking-up Gas Flow the path; One resetting-mechanism 40 becomes open this Gas Flow path in order to this closed component 30 is reset.

Above-mentioned body 20 has a room 21, this room is provided with an air inlet runner 22 that outwards is communicated with, these room 21 bottoms are formed with the bearing part 23 that a shape is not limit, this bearing part 23 is at least one movable closed component 30 of bearing, this closed component is for having a suitable weight and a ganoid ball in the present embodiment, and this bearing part 23 is provided with a through hole 24 that extends downwards, falls back blocking-up gas path for closed component.In the present embodiment, this through hole 24 has an end face of predetermined width at contiguous these bearing part 23 places, to form one first limited part 241, and this first limited part 241 is provided with one first seal ring 242, this through hole 24 is communicated with one and outward extendingly goes out flow channel 25, can make this closed component 30 leave original position when body 20 is shaken tumbles to this through hole 24, and fit tightly and seal this through hole 24 by its deadweight and first seal ring 242 on this first limited part 241, use flow channel 25 and be blocked.

Above-mentioned resetting-mechanism 40 has a guide rod 41 and is placed through in this through hole 24 in mode that can upper and lower slip, and this guide rod 41 is a nonplanar form near an end of these bearing parts 23, and it is the taper form that is deflection in the present embodiment.And these through hole 24 lower end inner edges convex with one second limited part 243, the end that this guide rod 41 is positioned at this through hole 24 has the external diameter big than this second limited part 243, it is unlikelyly dropped out outside this body 20 by this place, extend to then as for its thinner lower end that this body 20 is outer a predetermined length.More convenient in order to use, present embodiment also can install one first spring 42 additional and be sheathed on outside this guide rod 41, and props up this body 20 respectively and default on one first clasp 410 of these guide rod 41 lower ends with its two ends, bestows the downward thrust of this guide rod 41 1 with perseverance.With behind these closed component 30 these through holes 24 of sealing, can return back in this bearing part 23 by this this closed component 30 of guide rod 41 ejections, be connected with this air inlet runner 22 and make this go out flow channel 25.

At ordinary times, as shown in Figure 1, 2, this leak resistance set of pipeline 10 is when being in the open state that can pass through for gas, this closed component 30 is to be positioned on this bearing part 23, this guide rod 41 then is in the position of shrinking back to this through hole 24 lower ends, this air inlet runner 22 and this are gone out between the flow channel 25, can form unimpeded state via the through hole 24 that is blocked.

When earthquake takes place, as shown in Figure 3, because of vibrations produce rocking body 20, this phenomenon of rocking will make this closed component 30 leave original position and tumble to this through hole 24, and suppress first seal ring 242 on this first limited part 241 downwards by its deadweight, and then block the path that this goes out 22 of flow channel 25 and this air inlet runners, gas can't outwards be flowed out.

Above-mentioned through hole 24 from these air inlet runner 22 place's gas pressures, will further force this closed component 30 closely to be butted on this first seal ring 242 when being subjected to the state of these closed component 30 blocking-up, and it can not become flexible.And in the utilization of reality, this leak resistance set of pipeline 10 is fit to be arranged on the pipeline of the gas of carrying other kind or liquid equally.

For keeping the sealing state of 24 of this guide rod 41 and through holes, reveal by each position to prevent the gas in this through hole 24, therefore, further on this guide rod 41, be arranged with among the present invention and can be close to one second intermarginal in each guide rod 41 outer rim and the through hole 24 seal ring 43.

When the user desires to make this gas path recovery unimpeded, as shown in Figure 4, the user can upwards touch this guide rod 41, Yi Bian simultaneously make its tendency be moved upward to the height that is higher than these bearing part 23 positions simultaneously with this closed component 30 of top ejection of its non-planar form.Then, produce a lateral thrust, impel this closed component 30 laterally to move and return back on this bearing part 23 by guide rod 41 tops that are preset as the taper form that is deflection; Subsequently, the user can pull down or discharge this guide rod 41, utilizes first spring 42 to make this leak resistance set of pipeline 10 return back to as shown in Figure 1, 2 state.

Disclosed leak resistance set of pipeline 10 in the previous embodiment, no doubt had when earthquake takes place and to have cut off the effect of gas air feed path automatically, but bearing part 23 wherein can be designed to the non-form of horizontal plane that is, for example this bearing part 23 can be made as by the periphery towards the acclivitous form in through hole 24 places, make the bearing part 23 suitable angle D (as shown in Figure 5) that tilts, tumble the complexity of sealing the gas path to the through hole 24 because of rocking and can set this closed component 30 by the size that changes this angle D.Perhaps the periphery that this bearing part 23 can be adjacent to this through hole 24 designs the ring wall 231 (as shown in Figure 6) of a tool predetermined altitude H, and can set this closed component 30 and tumble the complexity of sealing the gas path to the through hole 24 because of rocking by changing this height H.

Moreover, the non-planar top of this guide rod 41 is except can being designed to aforesaid deflection taper form, also can be designed to spherical shape form as shown in Figure 5, perhaps pyramid form as shown in Figure 6, in other words, as long as the top of this guide rod 41 is designed to non-planar form, and can be when this closed component 30 of guide rod 41 top ejections is moved upward to the height that is higher than these bearing part 23 positions, can borrow the inclination on its top produce a lateral thrust and impel this closed component 30 to produce lateral displacements and return back to this bearing part 23 and get final product.

Previous embodiment structure of the present invention can reach the effect of automatic closing pipe line when earthquake takes place, but still has part-structure can improve that more GRAMERCY is perfect in the hope of making effect.Now explain with Fig. 2, because the next interim direction of rocking that produces of earthquake might not, when earthquake produced when rocking the direction that arrow A indicated among direction such as Fig. 2, closed component 30 just can fall into the effect that through hole reaches closing pipe line because of rocking easily, but when the direction of rocking that earthquake produced, during as arrow B indicated among Fig. 2 direction, closed component 30 is just easily along these bearing part 23 periphery pitch of the laps, and vibrations that need be bigger or time more of a specified duration just can fall into the effect that through hole produces closing pipe line.Therefore the inventor is improved in line with excelsior spirit again.

Please consult Fig. 7 to Figure 10 again, difference in the present embodiment between itself and aforementioned first embodiment, mainly be that several equidistant dividing plates 26 of being separated by are set in this room 21, as two, three or four, in the present embodiment for being provided with equidistant four dividing plates 26 of being separated by, for four closed components 30 place respectively by among each dividing plate 26 formed four rooms 210 as Fig. 7, shown in Figure 8.

Different but by opening direction all towards each room 210 of this first limited part 241, when making leak resistance set of pipeline 10 no matter afford from the rocking of variant directions such as east, south, west or north, at least the closed component 30 that can guide wherein falls into this through hole 24 exactly, to reach the effect of automatic closing pipe line.

And in order to prevent that several closed components from falling into through hole simultaneously, and cause closed component to be difficult for the situation out of control of returning position, the inventor is after deliberation several, and is little than the diameter of each closed component 30 with this first limited part 241 to the depth design of 23 of this bearing parts.Like this, after any closed component 30 falls into through hole 24, the apical margin of this closed component 30 will be higher than this bearing part 23, not only occupied the position of through hole, and its apical margin has also stoped other closed component 30 to continue to be moved to the position of through hole 24 again, it is still remained on the original position, therefore the problem of this closed component 30 storehouse in through hole more than two can not take place, or remaining closed component leaves the situation (as shown in Figure 9) of original position.

And, the diameter of this closed component 30 is designed to be slightly larger than the width of this bearing part 23, therefore when the closed component 30 that falls into through hole 24 is subjected to guide rod 41 to make progress ejection, will be subjected to the pushing and pressing of the part of other closed component 30 outstanding bearing parts 23, and impel this closed component 30 to tilt to original locality, the position that returns back to its script is pushed on the inclined-plane that is subjected to these guide rod 41 tops again, can prevent that so closed component 30 is difficult for the generation of the situation out of control of returning position.

In the present embodiment, no doubt be to lift four dividing plates 26 to be example, but in the utilization of reality, reach restriction or guide the mode that each closed component 30 only can advance towards these through hole 24 centers, except can adopting three of negligible amounts or quantity closed component 30 than each dividing plate 26 more than four and equivalent amount, or even in same room 21, a plurality of closed components 30 etc. are set, all belong to feasible equivalence techniques.

These through hole 24 inside in the above-mentioned body 20 further are provided with a sleeve pipe 244 that can supply this guide rod 41 to move back and forth therein, and this second limited part 243 is located at this sleeve pipe 244 inside, and this first spring 42 is to be made as to prop up between this first clasp 410 and this sleeve pipe 244.

Whereby this resetting-mechanism 40 is given modularization, make it both be convenient to be assemblied in this through hole 24, also be convenient to change simultaneously renewal.

Please cooperate and consult Figure 11 to Figure 13, the leak resistance set of pipeline 10 that present embodiment disclosed also is designed to and can the mode of pushing from top to bottom it be reset to open state, and it is more convenient to allow the user operate.

Its main structure is identical with previous embodiment, but further includes in this resetting-mechanism 40: a lever 44 is hubbed on this body 20, and its left end extends to this guide rod 41 belows; One button 45 is being hubbed in these body 20 default perforation 36 by upper and lower slide type, and its upper end stretches out the top of this body 20, and the lower end then extends to this lever 44 right-hand members top; One second spring 46 props up the corresponding position of each body 20 and button 45 respectively with its two ends, in order to support this button 45 in the position of projection upwards; One second clasp 47 is fixed in the lower end of this button 45, and is positioned at the below of this perforation 36, breaks away to this body 20 in order to prevent this button 45.

Whereby, because of earthquake converts this leak resistance set of pipeline 10 (as shown in figure 12) of closed condition to, can it can be reset to open state (as shown in figure 11) by the action of easily pushing this button 45 (as shown in figure 13) downwards and being discharged again.
