Abstract

The present invention provides one kind with negative pressure reflux is prevented, it includes a pedestal, and the pedestal one end is provided with an at least air intake vent, and the air intake vent penetrates the pedestal another end, and the precalculated position of the pedestal is provided with a supporting part and one first linking part；One obturator, the obturator one end is provided with one second linking part, second linking part is connected to close the air intake vent another end with first linking part, the obturator another end is provided with an air outlet, the supporting part penetrates the air outlet and the air outlet fits with the supporting part, whereby, the effect for preventing from deforming and preventing that negative pressure from flowing back effectively is reached.

Description

With preventing negative pressure reflux

Technical field

The present invention is to be a kind of with negative pressure reflux is prevented, espespecially one kind can effectively prevent negative pressure from returning by obturator Stream, and obturator also can be effectively supported by supporting part, to prevent the device of obturator deformation.

Background technology

Typically, it is effectively to prevent gas or liquid countercurrent, can often uses a check (non-return) valve to be installed on gas or liquid Entrance, so as to effectively preventing gas or liquid countercurrent, and during non-return, to avoid the generation of backflow, usual check (non-return) valve Head triangular shape can be presented, be triangle top be provided with an opening, effectively to reach non-return effect, so, if air pressure return The pressure of stream is higher, and return pressure can constantly oppress the side of opening two, then is easily deformed the phenomenon of leakage.

Therefore, in view of above-mentioned shortcoming, on market today someone in U.S. Patent Publication No. the US8276616B2nd " HIGH PRESSURES DUCKBILL VALVE AND INSERT (high pressure duckbill valve and insert) ", as shown in figure 1, it is wrapped A duckbilled body 11, a pedestal 12 and a supporter 13 are included, the one end of duckbilled body 11 is provided with an air outlet 111, the supporter 13 is set To support two sides inside the duckbilled body 11 inside the duckbilled body 11, the intensity so as to effectively strengthening the duckbilled body 11；

But, because the supporter only supports two sides inside the duckbilled body, and the air outlet that the duckbilled body is provided with and part The duckbilled body also there is no method effectively to be consolidated support by the supporter.

The content of the invention

Therefore, in view of this present inventor, is that invention is a kind of with negative pressure reflux is prevented, whereby, effectively reaching prevents The effect for deforming and preventing negative pressure from flowing back, with the shortcoming for existing product of forgoing, promotes its effect.

For up to the purpose above taken off, the main technical schemes that the present invention is provided include：

One kind, which has, prevents negative pressure reflux, and it includes a pedestal, and the pedestal one end is provided with an at least air intake vent, the air intake vent The pedestal another end is penetrated, the precalculated position of the pedestal is provided with a supporting part and one first linking part；And

One obturator, the obturator one end is provided with one second linking part, second linking part and first linking part be connected with The air intake vent another end is closed, the obturator another end is provided with an air outlet, and the supporting part penetrates the air outlet and the air outlet is with being somebody's turn to do Supporting part fits.

Pedestal as described above, wherein, the pedestal is further installed in inside a conductive gas with the obturator, by this Gas effectively can be directed at precalculated position by conductive gas.

Obturator as described above, wherein, the enclosure interior has a hollow space.

Obturator as described above, wherein, the obturator includes triangle, rectangle or trapezoidal.

Pedestal as described above, wherein, the center of the pedestal is provided with the supporting part and first linking part.

Pedestal as described above, wherein, the pedestal includes circle, triangle, rectangle or star.

To enable the above objects, features and advantages of the present invention to become apparent, hereafter hereby diagram is coordinated to enumerate specific reality Apply example.

Embodiment

To make your juror is convenient to understand present disclosure, and the effect that can reach, hereby diagram is coordinated to enumerate Specific embodiment, is described in detail as follows：

Fig. 2 to Fig. 4 is referred to, is stereo appearance figure, exploded view and the profile of the present invention, as illustrated, the main bag of the present invention A pedestal 2 is included, the one end of pedestal 2 is provided with an at least air intake vent 21, the air intake vent 21 is penetrated in the another end of pedestal 2, the pedestal 2 A supporting part 22 and one first linking part 23 are provided with the heart；

One obturator 3, the inside of obturator 3 has a hollow space, and the one end of obturator 3 is provided with one second linking part 31, should Second linking part 31 is connected to close the another end of air intake vent 21 with first linking part 23, and the another end of obturator 3 goes out provided with one Air port 32, the supporting part 22 penetrates the air outlet 32 and the air outlet 32 fits with the supporting part 22.

Fig. 5 to Fig. 8 is referred to, is the use state exploded view of the present invention, use state schematic diagram, air inlet schematic diagram and anti- Non-return flow diagram, as illustrated, the pedestal 2 is installed in inside a conductive gas 4 with the obturator 3, when set by the one end of pedestal 2 The air intake vent 21 having is imported after a gas, because first linking part 23 and second linking part 31 are connected to close the inlet air Mouthful 21 another ends, therefore the air outlet 32 that the gas is had to be provided with from the another end of the obturator 3 exports, if conversely, the gas is intended to Enter fashionable from the air outlet 32, because the air outlet 32 fits with the supporting part 13, therefore the gas is then had to flee to the envelope Outside closure 3, and it cannot be introduced into inside the obturator 3, furthermore, and because the supporting part 13 can effectively support the air outlet 32, i.e., When the gas backstreaming is caused negative pressure and is extruded the air outlet 32, the air outlet 32 also will not be because that can not become load its pressure Shape, in this way, the effect for preventing from deforming and preventing that negative pressure from flowing back can effectively be reached.

Fig. 9 is referred to Figure 10, is embodiments of the invention figure, as illustrated, the present invention can be by trapezoidal, square, triangle Shape or the shape of other geometric figures are constituted, so as to reaching and identical effect person of the present invention.

It is described above, only highly preferred embodiment of the present invention, when the scope that the present invention is implemented can not be limited with this；Therefore, it is all The simple equivalent changes and modifications done according to the claims in the present invention and description of the invention content, all should still belong to patent of the present invention In the range of covering.
