When discharging, the Ministry found that the bottom of the container 1 will leak deep into the oil leakage. It will be found that, as shown in Figure 2, the inverted oil 'aggregate container u is next to the cover body; the surface float U is far away Float 16 丨: Make: Yu: Night force with the action bar 17 is biased, ^ ', in response to the floating pendulum, the plug body 18 is no longer blocked, * eliminate ^ the shortcomings, causing the oil to flock to the ground "Worker male 7 male entry / claw road 22, and then accumulated in the exhaust Jing 14 inside, not only affects the exhaust effect or pressure relief performance, more in line with the external environment of the cylinder 10 pollution. Discharge, therefore, how to prevent the inverted period The disadvantages of the external leakage are the problems to be solved in the present invention. [Invention] In view of the fact that the present inventors have intensively studied the problems of the prior art, f has been engaged in the research and development and manufacturing of related industries for many years, and seeks solutions. Finally successfully developed a kind of "floating structure improvement" to improve the use The problem of Ming. The purpose of the county is to use: Gravity by means of 'overcoming the traditional buoyancy type (4) structure in the shortcomings of taking _ 3 leakage, eliminating (four) environmental pollution factors, avoiding the impact of pressure or pressure relief. One of the main purposes of the invention is that, with the means of buoyancy, it will become a buoyant leakage-proof structure with free fall performance, which is relative to the low probability that the 2012200014 system will cause leakage during the inverted period. In order to achieve the object, the present invention provides an improved buoyancy leakage preventing structure, which is suitable for a cylinder composed of the following elements: a cover is sealed in the opening of a container, and a discharge cylinder is supported in the container; the cover has a The outlet, the first-class road and a leak-proof structure communicate the container and the exhaust pipe through the flow channel. The technical core of the leak-proof structure is to restrict a weight to a pipe leading to the flow channel for free fall movement. A heavy object is an object of a mass that is weighted by the attraction of gravity to cause the object to fall to the ground. To help the reader understand the essence of the present invention, The cylinder of Figures 3 and 4 is taken as an example to illustrate the specific case of the present invention in combination with the conventional leak-proof structure. In Figure 3, the cover 20 is formed with a passage B which is regarded as a pipe and connects the flow passage 22, The weight A can be placed and the opening can be closed, so that the weight A moves freely in the channel B. In the figure, the cylinder 10 maintains the upright state and is filled with the liquid 15, and the liquid surface holds the float 13 to touch the float. 16. The movable rod 17 is yawed so that the plug body 18 blocks the outlet of the flow passage 22. At this moment, the weight A falls by gravity to the surface direction, and does not have a blocking clogging effect. Although the gas of the flow passage 22 has buoyancy. However, it is not enough to hinder the fall of the heavy object A. As shown in Fig. 4, when the cylinder 10 is inclined to an inverted state which is close to the vertical ground, the floating object 13 floats on the liquid surface, the floating ball 16 The yaw of the movable rod 17 is caused by the buoyancy, so that the plug body 18 leaves the outlet of the flow passage 22. At this moment, the liquid 15 that has flowed into the flow channel 22 is blocked by the free-falling weight A at the intersection of the flow channel 22 and the channel B, preventing the flow of the liquid 15 5 201248014: the internal gas of the exhaust pipe is contaminated by the gas The effect or pressure relief performance is affected. For the purpose of gravity and buoyancy, the surface structure is free from the clogging function of the falling body, and the purpose, structure and characteristics/solutions of the relevant embodiments will be explained. [Implementation] Please (4) 5G 3 ' Also close the lid body 40 at the partially closed container mouth 35 to support the exhaust cylinder 5 〇 stably standing in the valley 31 Internal and unshakeable. The bottom end of the boundary container 31 is a closed end 32, which is mounted outside the closed end 32, and is centrally arranged/closed at the closed end 32, and the wall of the exhaust cylinder 5 is surrounded by the check valve 34. The trough 31 and the exhaust cylinder 5 are respectively divided into two internal spaces. The cover body 40 has a disc-shaped body, and a top surface thereof is formed with a grip 41, an outlet 42 and a flow passage 43 so as to be locked to the open end of the container 31, and the outer wall fluid enters the container 31 through the outlet 42. The internal work chamber a ^ indirectly enters the inside of the exhaust cylinder 50 via the flow passage 43. The flow passage is multi-formed and formed inside the cover body 40 by injection molding technology, and some of the outlets are blocked by a pressure relief valve 44 and other plugging materials. The rest, 77 leaves the inner space leading to the trough 31 and the exhaust pipe 5. The flow path 43 leads to the outlet of the container 31, and can be blocked by a leakage preventing structure 60 coupled to the cover 4〇. The gas cylinder 50 has a long rod 52 and an exhaust valve 53 therein, and the length is 201248014 ς! 2 t ^ through the flow passage 43 of the cover body 40, deep into the hollow exhaust cylinder 〃, the exhaust valve 53 is connected. The other end of the long rod 52 The cover body 4 is exposed to the outer grip 41 and connected to a gripping rod 51, and the cover 40 is squiggly reciprocated relative to the exhaust cylinder 50. Μ 5 grips the cymbal 51, and the long rod 52 drives the exhaust valve 53 follows, 22, 0, 0 inner wall displacement in the same direction 'simultaneously squeezes the front of the exhaust pipe 50 inside the gas 53. The grip bar 51 is forced to lower the fort, causing ^ 1 3 to compress the exhaust cylinder 50 The bulk density, from the check valve 34 outwards [^, according to the siphoning phenomenon, the flow passage 43 draws the internal gas of the container 31 = the gas cylinder 50. Then, see the sixth figure, since the energy port of the container 31 is closed and protrudes into a tube The body c is made to be closed inside: When the milk is broken, a vacuum state is formed, and the external fluid passes through the pipe c to continue into the surface: high, and finally touches the leakproof structure. In the figure 7:8, the leak-proof structure 60 is known to be in the cover 40. The outer outer tube (9) (4) is regarded as a pipeline, which communicates with the opening of the flow passage 43"1, and is limited. The spherical weight is 7 〇 and a floating motion. Do not pay to leave the foreign official 8 〇 ' and can be free fall in the pipeline ^ 盍 body 40 forming - deep into the outer tube 8 〇 base tube 6 ι, boundary positioning: the official 80 - end for the large diameter # 63 'tolerance The base pipe 61. A small charge is formed deep in the base pipe 61; the flow path 43 is communicated with the main passage J, and the end of the main J is leaked. The outer portion of the base pipe 61 is adjacent to the inner opening 64 of the plurality of through-tubes 61, and is integrated with the outer tube (10) 7 201248014 and the connecting end 81 by one of means such as screwing or pasting. The connecting end 81 of the outer tube 80 is open, and the other end is a closed restricting end 82. The restricting end 82 and the outer tube 8 are formed with a plurality of outer communicating openings 83, and the outer opening 83 is kept outside. At the same time, the ring-shaped restricting end 82 is provided for the falling floating body 71 to prevent the weight 7 from leaving the base pipe 61. The floating body 71 forms a small diameter section 72 and a The large diameter section 73 has a hollow space inside. In the figure, the free end of the small diameter section 72 does not leave the large diameter end 63 of the base pipe 61, and the falling end is subjected to the falling weight 70. The large diameter section 73 is subjected to The outer tube body 71 is limited to be displaced along the tube length direction. When the sub-return is returned to the sixth embodiment, the liquid 15 is continuously injected into the cylinder 30 in the erect state, and flows into the outer port 83 of the leakage preventing structure 6A through the inner port 64. Enter the base officer 61. The rising liquid level will support the floating body 71, and then move against the object 7G to move up until the touch And the leakage ring & the surface of the leakage ring 66 is bundled from the outside to the inside by a cone 68, and the weight 70 is guided to block the center of the leakage ring 66 through a hole 67, so that the base pipe μ and the flow path U The flow is no longer clear, preventing the liquid 15 from entering the flow path 43. From Fig. 9, it is understood that the liquid 15 inside the container 31 is emptied, and which tube 3G must be tilted to an inverted state like a vertical ground, so that the liquid 15 can be passed through the outlet. 42 flows out. The liquid 15 collected in the container 31 adjacent to the 40-position of the cover body flows into the e-path of the outer tube (10) leading to the base tube 61 to float the floating body 71 and abut against the restriction end 82. The weight at this moment: 70 ' < Gravity Attraction The generated weight will be greater than the buoyancy, naturally it will fall toward the hole and block the through hole 67, overcoming the drawbacks of the external leakage caused during the inverted period of the traditional palpebral cylinder. 201248014 According to the foregoing structure, the following embodiments can be derived. For example, in (7), the difference between the force and the leakage prevention structure of the present invention is that the small diameter end 62a no longer extends the base tube, and (4) is combined with the open connection end 81a of the outer tube 8〇& The appearance of the floating body 7U is changed into a hollow cylinder with a single-diameter. The heavy object is changed to the polygonal body 'even if there is no leak stop ring', it can block the opening of the flow path 43a during the upright or inverted period like the first one or the eleventh. The buoyancy type leakproof structure of Fig. 12 The difference of the embodiment of the first FIG. 1G is that the f-weighted object 70b has a head and a long guiding portion 75b' the head portion 74b is engaged with the guiding portion 75b, and is dropped by gravity and is blocked at the limiting end 82b. Leaving the outer tube 8〇b. The guiding portion passes through the outer opening 83b of the limiting end 82b, partially exposing the outer tube 8〇b, allowing the exposed end to be supported by the floating surface 13b floating on the liquid surface, with a polygonal head The portion 74b blocks the opening of the small diameter end 62b into and out of the flow path 43b. In Fig. 13, the floating surface 13b floating on the liquid surface is in an inverted relationship and is hidden from the outer tube, and the weight 7〇b is still hitting the ground by weight and blocking the opening of the small diameter end 62b. The buoyancy type leakproof structure of Fig. 14 is different from that of the Fig. 12 embodiment in that the head portion 74c forms a second ridge portion 76c at the intermediate portion of the end surface. During the erecting period, the exposed end of the guiding portion 75c touches the floating object 13c floating on the liquid surface, and the associated guiding portion 75c drives the head portion 74c to rise straight in the outer tube 8〇c with the support of the wall surface of the outer opening 8 Until the bulging portion 76c blocks the opening of the small-diameter end 62c into the flow path 4沘. In Fig. 15, the floating object floating on the liquid surface is separated from the outer tube 80c by the reverse relationship, and the weight 70c is still dropped to the ground by the weight, so that the raised portion 76c blocks the opening of the small-diameter end 62c. 201248014 The buoyancy type leakproof structure drawn in Fig. 16 is different from the u-th embodiment in that the head portion 74d of the weight 70d is at the end surface; the portion recessed-accommodating portion 77d, and the housing portion 77d is surrounded by the wall surface. Load-ball plug 78d. When the liquid level 13d is pressed against the exposed end of the guiding portion 75d due to the erect relationship, the pipe formed by the inner wall of the outer pipe of the weight 70dS rises, and the cool body 78d blocks the flow path of the small pipe end 62d. The opening of the track 43d is as follows: In the figure, the float 13d floating on the liquid surface is away from the outer tube 80d due to the inverted relationship, and at the same time, the wall of the outer port 83d of the restricting end 82d is supported by the guide portion. The weight object is freely falling toward the ground according to the weight, and the plug body 78d is pushed to block the opening of the small pipe diameter end 62d. The buoyancy type leakage preventing structure of the 18th drawing is different from the first embodiment in that the plug body 78e is changed from the solid (10) to the hollow body. The hollow plug body 78e is limited to the v shape of the receiving portion 77e. The wall surface does not roll freely during the erecting period.
