Detailed Description

In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to the attached drawings 1-6, the utility model discloses an intelligent vacuum safety valve, which comprises an upper valve head 1 and a lower valve head 5, wherein the upper valve head 1 and the lower valve head 5 are tightly buckled with each other to form a cavity inside, and a valve core 2 for automatically plugging a gas channel opening is arranged in the cavity; the cavity comprises a first air passage 6 which is vertically folded, a second air passage 7 which is connected with the first air passage 6 and a third air passage 8 which is connected with the second air passage 7; the second air passage 7 is positioned between the first air passage 6 and the third air passage 8, the air passages are distributed in a staggered manner, and one end of the vertically folded first air passage 6, which is close to the second air passage 7, is a turning opening; the third air passage 8 is an air inlet, and the second air passage 7 is positioned on the right side of the third air passage 8 and communicated with the turning port.

The valve core 2 is positioned in the second air passage 7 and used for plugging an air passage opening and preventing vacuum leakage; the valve core 2 is in a sphere shape, and any section of the sphere is in a circle shape, so that the characteristic that the air passage can be completely closed by the valve core 2 is ensured.

A filter disc 3 is arranged between the second air passage 7 and the third air passage 8 and is used for filtering sundries and preventing the sundries from entering the air passages to cause blockage; the sucking disc 9 is an external sucking disc, and the sucking disc 9 is connected with the lower valve head 5; inlay between sucking disc 9 and the lower valve head 5 and be equipped with gasket 4, inlay the gap department of establishing between sucking disc 9 and lower valve head 5, can prevent the not hard up between sucking disc 9 and the lower valve head 5, strengthened the steadiness, and avoided the production of noise.

The gasket 4 of the present invention functions to seal and fasten, and specific embodiments thereof include, but are not limited to, a gasket, a sealant, a seal ring, and the like having the same function.

When the vacuum safety valve is used vertically, the valve core 2 is separated from the turning port of the first air passage 6 under the action of gravity, so that the air passage is opened; when the vacuum is opened and the sucking disc 9 does not suck the product, the air flow rapidly pushes the valve core 2 to the turning port of the second air passage 7 to block the air passage, and the pressure difference (vacuum and atmospheric pressure) at the two sides of the valve core 2 can make the valve core 2 more tightly close the turning port, so that the function of automatically and completely cutting off the vacuum air passage is realized.

Secondly, the one end of the first air flue 6 that erects to break has the bending mouth, and the bending mouth is linked together with second air flue 7, because the case 2 sets up in second air flue 7, this case 2 has a small amount of drops in second air flue 7, makes the valve when not leading to the vacuum, or leads to the vacuum and inhale the article simultaneously, and case 2 does not have the drive of air current to under the action of gravity, form the certain distance with the gas flue mouth, thereby can keep unobstructed of air flue.

The sucking disc 9 is matched and assembled with the lower valve head 5 of the vacuum valve, and an air inlet channel is arranged in the middle and communicated with the third air channel 8 of the lower valve head 5 for sucking objects.

Referring to the attached figure 2, when the suction cup 9 at the lower end of the vacuum valve does not suck articles or has leakage, and when the air flow enters from the third air passage 8, the air flow makes the valve core 2 block the turning port of the first air passage 6 rapidly, and the turning-off of the air passage is maintained due to the pressure difference between the two sides of the valve core 2, thereby realizing the purpose of reliably and completely turning off the vacuum.

Referring to fig. 3, when the suction cup 9 at the lower end of the vacuum valve completely sucks the article without leakage, the valve core 2 is not pushed by the air flow and the pressures at the two sides are equal, and the valve core 2 automatically breaks away from the turning opening of the first air passage 6 under the action of gravity, so that the air passage is kept smooth and the article is effectively sucked. And the turning mouth of the first air duct 6 is horizontally arranged, so that the same function can be completed no matter the application is vertical or inverted.

Referring to fig. 4, which is a schematic view of a pneumatic symbol of the intelligent vacuum safety valve, in the figure, P is a vacuum source inlet, and a is a suction cup 9 end inlet.

Referring to fig. 5, when a plurality of vacuum valves are used simultaneously, the vacuum valves suck the liquid through the external main valve, and the object is large so that all the suckers 9 can be closed; the vacuum valve can be reduced in specification or changed in shape; referring to fig. 6, some suction cups 9 cannot suck the product, and at this time, the vacuum safety valve can quickly and reliably close the whole vacuum of the vacuum air path without leakage, thereby ensuring good suction of the object.

Due to the functions, the safety valve can effectively absorb objects with different sizes and different shapes by the same mechanism, and can absorb products with different specifications by the same multi-sucker 9 structure.

In summary, the intelligent vacuum safety valve can automatically turn off the device of the vacuum gas circuit of the suction cup 9 which does not suck the articles without the control of any electric appliance, and can prevent the mechanical valve of vacuum loss. The valve with a pure mechanical structure is simple to install, reliable in performance, capable of greatly saving cost and capable of providing reliable and economical accessories for automation of intelligent material suction.
