Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1 to 8, the following embodiments of the present invention are provided:

As shown in fig. 1 to 6, a first embodiment of the present invention proposes a valve comprising:

a valve seat 1;

a valve body 2 connected to the valve seat 1;

A valve core 3 having a sealing end 301 and a shaft coupling end 302, slidably connected to the valve body 2;

a driving member 4 having a connecting end 401 and a driving end 402;

Wherein the connecting end 401 is connected with the valve seat 1;

wherein the driving end 402 is connected with the shaft coupling end 302 of the valve core 3;

Wherein the driving piece 4 drives the valve core 3 to move along the axial direction of the valve seat 1;

a confluence structure 5 provided at a sealing end 301 of the valve element 3;

a breathing structure 6 provided to the confluence structure 5;

Wherein the confluence structure 5 guides the medium in a first direction;

Wherein the first direction is the direction in which the sealing end 301 points to the breathing structure 6;

Wherein the breathing structure 6 is deformable by a driving force.

In the present embodiment, the valve seat 1 is used for the valve assembly. The valve body 2 presents a cone structure with a cavity, and the valve core 3 is slidably connected in the cavity structure of the valve body 2. The bottom of the valve body 2 is provided with a liquid outlet 201, and the liquid outlet 201 is plugged or opened through a sealing end 301 of the valve core 3 to realize the opening and closing of the valve. Wherein the clearance between the valve body 2 and the valve core 3 can be adjusted by the driving piece 4. Specifically, the driving member 4 may be an air cylinder, and the air cylinder drives the valve core 3 to perform displacement motion along the axis of the valve seat 1, so that the gap between the valve body 2 and the valve core 3 is adjusted, and the amount of medium flowing through the gap is changed.

In addition to the above, a confluence structure 5 is added. The confluence structure 5 is used for guiding the medium. When the sealing end 301 of the valve core 3 completely seals the liquid outlet 201 of the valve body 2, a part of small amount of liquid is still discharged from the liquid outlet 201, so that the valve medium leaks. Therefore, the medium is guided by the confluence structure 5 to be collected in the same area, and the medium is adsorbed in the area due to the adhesion of the liquid, so that the problem of medium dripping is effectively alleviated.

It has further been found that during the medium flowing out of the outlet 201, part of the liquid will be adsorbed on the surface of the valve core 3, thereby causing saturation of the liquid on the surface of the valve core 3. Thus, even if the confluence structure 5 is added, the guided medium cannot be adsorbed to the surface of the saturated valve body 3, and thus there is still a problem of medium dripping.

Based on this, the breathing configuration 6 is further increased. The breathing structure 6 is essentially such that the medium deposited in the saturation region drops by deformation, which in turn enables this region to further absorb the guided medium. The breathing structure 6 is deformed when the valve is closed, so that the saturated medium adhering to the surface drops and follows the medium that has flowed out into the filling container. At this time, the surface of the breathing structure 6 is in a medium unsaturated state, so that the medium guided thereto by the guide structure can be adsorbed, thereby avoiding medium dripping in the filling bottle in a transport state.

In summary, according to the valve provided in this embodiment, the adsorption capacity of the medium is increased by changing the adsorption capacity of the medium on the surface of the breathing structure 6, so that the problem of medium dripping is effectively avoided.

As shown in fig. 3 to 4, a second embodiment of the present invention proposes a valve, and the confluence structure 5 includes, on the basis of the first embodiment:

a converging body disposed at the sealing end 301;

Wherein, the converging body and the sealing end 301 are integrally formed and connected in a smooth manner;

wherein the bus body has:

a guide surface 501 and a converging aperture 502;

Wherein the converging body is in a shape of a circular truncated cone;

wherein, the guiding surface 501 is a side wall surface of the truncated cone;

wherein, the converging hole 502 is arranged on the table surface of the round table.

In this embodiment, the busbar takes the shape of a truncated cone. When the sealing end 301 of the valve core 3 seals the liquid outlet 201 of the valve body 2, the confluence body is arranged protruding from the liquid outlet 201. At this time, the medium slowly flows on the guide surface 501 and gradually merges into the position of the confluence hole 502. And breathe the structure 6 and install in the position of converging hole 502, and breathe the structure 6 and take place deformation in this position for its surface is in the medium drip of saturation adsorption state, provides sufficient adsorption surface for the big liquid drop of guided shaping, and then ensures that the size of adsorption affinity is greater than the gravity of big liquid drop, finally realizes avoiding big liquid drop drip's problem.

As shown in fig. 1 to 6, a third embodiment of the present invention proposes a valve, and on the basis of the above embodiment, the valve element 3 has:

a pipe 7 arranged along the axial direction of the spool 3;

wherein the tubing 7 has a first port 701 and a second port 702;

wherein the first port 701 communicates with the confluence hole 502;

wherein the second port 702 is used for connecting with a negative pressure generating device 8.

In this embodiment, it has further been found that if the breathing structure 6 is not capable of generating a sufficient amount of deformation, the medium adhering to its surface will not be able to vibrate and drip more effectively, and thus the large droplets to be guided subsequently will not be able to be effectively adsorbed.

Based on this, by adding the negative pressure generating device 8, the pipeline 7 is further made to be in a negative pressure state, and finally, the breathing structure 6 is made to generate a larger deformation amount, so that the medium adsorbed on the surface of the breathing structure is effectively dripped.

Also, in the prior art, there is a structure in which the medium is adsorbed by the negative pressure generating device 8 so that the medium enters the pipe 7, thereby avoiding dripping of the medium. However, in the field of filling, particularly when the filling medium is an oily medium, the oily medium adheres to the inner wall surface of the pipeline 7, and after long-term use, the pipeline 7 is blocked, so that the medium cannot be effectively adsorbed. Moreover, since the pipe diameter of the pipe 7 is generally small, the cleaning work is very difficult.

In contrast, in this embodiment, the deformation of the respiratory structure 6 is increased by the negative pressure generating device 8, and the medium cannot enter the pipeline 7, so that the problem that the pipeline 7 is blocked and the medium cannot be adsorbed is avoided.

As shown in fig. 5 to 6, a fourth embodiment of the present invention proposes a valve, and on the basis of the above embodiment, the breathing structure 6 includes:

a breathing plate 601 provided in the confluence hole 502;

wherein the breathing plate 601 is elastic;

Wherein the breathing plate 601 has a rough confluence surface 602.

In this embodiment, the breathing plate 601 is elastic, and a rubber material may be used for securing the sealing property.

To further increase its attraction to the guided media, the converging surface 602 is roughened to increase the attraction of the media.

The above structure does not cause a problem that the medium in a saturated adsorption state cannot be vibrated and dripped, because the vibration force generated by the deformation of the converging surface 602 makes the action of the medium dripping significantly stronger than the adsorption action of the coarse structure on the medium. Also, the present embodiment is expected to improve the adsorption force to the large droplet guided thereto to avoid the problem of dripping thereof.

A fifth embodiment of the present invention proposes a valve, and based on the above embodiment, the converging surface 602 has:

A capillary structure;

Wherein the capillary structure is a plurality of micropores;

or, the capillary structure is a dry etching line.

In this embodiment, the capillary structure is further increased.

Because the liquid medium can obviously depend on the capillary structure, the specific surface is that the liquid medium can flow and adsorb along the path of the capillary structure, thereby effectively increasing the adsorption force of the medium.

Based on this, the capillary structure may be provided as a structure of micro-holes or etching lines. When the large droplet is guided to the converging surface 602, due to the existence of the micro holes or the etching lines, the large droplet can enter and fill into the structures, so that the contact area between the large droplet and the converging surface 602 is increased, the adsorption effect of the large droplet and the converging surface is further improved, and the form of difficult dripping is finally shown.

As shown in fig. 5 to 6, a sixth embodiment of the present invention proposes a valve, and on the basis of the above embodiment, the breathing plate 601 has:

A connecting member 603 and a deforming member 604;

wherein the connector 603 is located at an edge of the breathing plate 601;

wherein the connecting piece 603 is in sealing connection with the bus hole 502;

Wherein the deformable member 604 is deformable;

wherein the connecting member 603 is connected to the deforming member 604.

In this embodiment, the connection member 603 is elastic, such as rubber, which is used to ensure tightness between the breathing plate 601 and the liquid outlet 201. Also, the deforming member 604 is elastic for deforming.

In a specific embodiment, the connecting member 603 is a rubber ring, and the deforming member 604 is a rubber plate, which are integrally formed.

Negative pressure is formed in the pipeline through the negative pressure generating device 8, so that the rubber plate is deformed, and the concrete process of deformation is as follows: the rubber sheet is bent towards the pipeline 7 and away from the pipeline 7. In this process, the surface-adsorbed medium is caused to drip.

As shown in fig. 5 to 6, a seventh embodiment of the present invention proposes a valve, and, based on the previous embodiment, the deforming member 604 has:

A media anchoring structure 9;

Wherein the media anchoring structure 9 is at least for providing a plurality of physical contacts for the media;

Wherein the physical contact is the point where the medium contacts the deformable member 604.

In this embodiment, the media anchoring structures 9 are added to further enhance the adsorption capacity for the media.

In particular, the media anchoring structures 9 are used to provide physical contact. That is, by increasing the number of points of contact between the medium and the deforming member 604, the contact area between the medium and the deforming member 604 is increased. Wherein an increase in physical contact means an increase in the contact area between the deformable member 604 and the medium. As the contact area increases, more intermolecular forces such as van der waals forces, electrostatic attraction, etc. may occur, thereby enhancing the adsorption force and helping to reduce leakage and dissipation of the medium.

Of course, at the microscopic level, each physical contact can be considered a tiny adsorption site that effectively "traps" the passing molecules. As the number of physical contacts increases, the deformable member 604 is able to effectively interact with more molecules, thereby improving the adsorption efficiency. Moreover, evenly distributed physical contacts on the surface of the deformable member 604 may create a more uniform dispersion force, which may help to more evenly distribute stresses within the media, reduce the formation of high stress areas, and thereby avoid media dripping. And, the design of physical contact can optimize the flow path of fluid, reduces vortex and backward flow emergence. This hydrodynamic improvement not only improves adsorption efficiency, but also improves overall valve performance, reduces pressure loss, and improves flow control accuracy.

As shown in fig. 6, an eighth embodiment of the present invention proposes a valve, and on the basis of the above embodiment, the medium anchoring structure 9 includes:

an anchor groove 901;

the anchoring groove 901 is radially formed with the center of the deformable member 604 as the origin.

In this embodiment, the media anchoring structures 9 are in the form of anchoring slots 901.

When the medium is attached to the surface of the deformable member 604 (i.e., the aforementioned converging surface 602), the medium can permeate into the anchoring groove 901 due to the existence of the anchoring groove 901, and the wall of the anchoring groove 901 can capture the medium and increase the contact area thereof, thereby effectively improving the adsorption capacity to the medium.

Specifically, the anchoring groove 901 presents a groove structure, the design of which is based on the surface of the deformable member 604. The radial design of the anchoring groove 901 takes the center of the deformable member 604 as the origin, which is helpful for uniformly distributing the pressure of the medium, reducing the local pressure concentration and further reducing the problem of medium stress concentration. Also, the presence of the anchor slots 901 provides a physical "anchor point" for the media as it flows over the surface of the deformable member 604. As the medium flows over the surface of the deformable member 604 (the converging surface 602), a portion of the medium enters the anchor groove 901. Since the groove wall inside the anchoring groove 901 has a certain depth and area, this increases the surface area of the medium in contact with the valve, thereby improving the adsorption capacity, helping to prevent the medium from being detached from the valve surface under high flow rate or high pressure conditions, and increasing the control accuracy and reliability of the valve. The anchoring groove 901 effectively improves the adsorption force by increasing the contact area of the deformable member 604 with the medium. This is because the larger the contact area, the larger the number of molecules in contact with the medium per unit time, thereby enhancing the adsorption force between the molecules and further improving the overall control effect on the medium.

Therefore, the anchoring groove 901 not only structurally provides a physical anchoring point, but also enhances the adsorption effect from the molecular level by increasing the contact area, thereby effectively relieving the problem of medium dripping.

As shown in fig. 5, a ninth embodiment of the present invention proposes a valve, and on the basis of the above embodiment, the medium anchoring structure 9 includes:

An anchor hole 902;

wherein the anchoring holes 902 are arranged in an array on the wall surface of the deformable member 604.

In this embodiment, the media anchoring structures 9 are in the form of anchoring holes 902. Which are small holes designed in the wall of the deformable member 604, which are typically arranged in an array configuration. The array structure may be regular (e.g., matrix, circular arrangement) or irregular.

The primary function of the anchor holes 902 is to create more points of contact between the deformable member 604 and the media, thereby increasing the residence time and contact area of the media on the surface of the deformable member 604. Specifically, the anchor openings 902 effectively extend the residence time of the medium at the surface of the deformable member 604 (i.e., the converging surface 602) by providing temporary "storage" space for the flowing medium. The increase in residence time allows the medium to participate more in the reaction or interaction of the surface, thereby enhancing the drip-proof effect of the medium. Also, the presence of the anchor holes 902 essentially adds an additional "micro-surface" to the surface of the deformable member 604. These tiny holes increase the actual surface area of the deformable member 604, and the increased surface area provides more opportunities for media molecules to contact the deformable member 604 surface. This increase in contact area is extremely important to enhance physical adsorption, thereby effectively avoiding the problem of massive dripping of the medium.
