[0002] The micro-jet diamond interaction chamber is mainly used in micro-jet high-pressure homogenizer.

[0003] When solid-liquid or liquid-liquid mixed materials are pressurized and pass through the interactive cavity channels of hundreds of microns to form supersonic jets, violent shearing, collision, cavitation, pressure drop and counter-emission effects are generated inside the diamond interactive cavity, causing the material to undergo efficient particle size reduction, and increase emulsification, homogeneity and transparency.

[0004] Conventional homogenizing chambers are Y-shaped and Z-shaped. Materials can only enter from one end of the interactive chamber and exit from the other end. The material cannot flow in the opposite direction to achieve homogenization of the material, thus affecting the homogenization efficiency of the material.

[0005] Therefore, how to design a high-pressure interactive chamber that can change the material flow direction and improve the material homogenization efficiency has become a technical problem that needs to be solved urgently by people in this field. Utility Model Content

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The present embodiment provides a reversible high-pressure interactive chamber, which is mainly used for homogenizing mixed materials, realizing reverse flow of materials, and improving homogenization efficiency of materials.

[0026] like Figure 1 and Figure 4 As shown, it includes a valve body 1, wherein a valve cavity 10 is provided in the valve body 1, and both ends of the valve body 1 are provided with connection ports 11 connected to the valve cavity 10, and the inner walls of the connection ports 11 are provided with internal threads, and the valve cavity 10 is spherical, and a spherical valve core 3 rotatably connected through a rotating shaft 33 is provided inside the valve cavity 10, and the spherical valve core 3 is provided with a coaxial input port 31 and an output port 32, wherein the input port 31 and the output port 32 are connected and located at the axis of the spherical valve core 3, as shown in FIG. Figure 2 As shown, the longitudinal section of the input port 31 is conical, the longitudinal section of the output port 32 is cylindrical, and the output port 32 is connected to the smaller side port of the input port 31, wherein during use, the input port 31 is aligned with one of the connection ports 11 on the valve body 1, and the output port 32 is aligned with the other connection port 11 on the valve body 1.

[0027] It is worth noting that the line connecting the two connecting ports 11 on the valve body 1 is perpendicular to the axis of the rotating shaft 33 .

[0028] Through the above settings, when the mixed materials are being homogenized, such as Figure 2As shown, at this time, the material enters from the input port 31 and then outputs from the output port 32. As shown by the arrow, the material enters the input port 31. During this process, the diameter of the input port 31 gradually decreases, and the material flows at a high speed. After the material is output from the output port 32, it enters the connecting port 11 on the lower side of the valve body 1. At this time, the material flow rate is reduced. After the material flows through the spherical valve core 3, the pressure is reduced, thereby achieving the effect of homogenizing the material and reducing the particle size of the material.

[0029] Usually, if Figure 2 As shown, the connection port 11 on the side of the valve body 1 is connected to the input pipe, and the connection port 11 on the lower side of the valve body 1 is connected to the output pipe. When the material enters from the upper connection port 11 and is output from the lower connection port 11, a primary homogenization process of the material is realized. When the input pipe and the output pipe are not removed, in order to improve the homogenization efficiency of the material, the spherical valve core 3 can be rotated around the rotating shaft 33 to switch the connection state between the input port 31 and the connection port 11 therein, so that the functions of the input pipe and the output pipe can be switched, and the material can flow in the opposite direction in the valve body 1 to realize the secondary homogenization of the material.

[0030] In order to realize the rotation of the spherical valve core 3, in this embodiment, Figure 2 and Figure 4 As shown, the valve body 1 is provided with a shaft groove 12 connected to the valve cavity 10, wherein a shaft 33 is inserted into the shaft groove 12, wherein the shaft groove 12 on one side is connected to the outer wall of the valve body 1, and the shaft 33 extends out of the shaft groove 12, and a knob 34 is fixedly installed on one of the shafts 33.

[0031] With the above arrangement, when the material needs to flow in the reverse direction, the knob 34 is rotated 180 degrees, thereby changing the connection port 11 aligned with the input port 31, so that the pressure drop of the material can also be changed when the material flows in the reverse direction, thereby homogenizing the material.

[0032] In order to clearly observe the state of the spherical valve core 3, Figure 1 and Figure 3 As shown, the knob 34 is provided with an indicating arrow 341, wherein the direction of the indicating arrow 341 indicates the flow direction of the material. In order to clearly understand that the spherical valve core 3 rotates 180 degrees, in this embodiment, as shown in FIG. Figure 3 As shown, an indication mark 13 is also provided on the side wall of the valve body 1. When the indication arrow 341 is aligned with the indication mark 13, it indicates that the spherical valve core 3 rotates to a specified position.

[0033] Since the interactive chamber is used in a high-pressure environment, in order to prevent the spherical valve core 3 from moving during use, in this embodiment, Figure 2As shown, it also includes a connector 2, wherein the outer wall of the connector 2 is provided with an external thread that is threadedly connected to the inner wall of the connecting port 11, such as Figure 3 and Figure 5 As shown, the connector 2 is also provided with an extension tube 21, and the spherical valve core 3 is also provided with a blocking end 30. When the indication arrow 341 is aligned with the indication mark 13, by rotating one of the connectors 2, the end of the extension tube 21 is abutted against the blocking end 30 of the spherical valve core 3. At this time, the connector 2 is connected to the output port 32. The other connector 2 is rotated to make the extension tube 21 on the connector 2 inserted into the input port 31. The end wall of the extension tube 21 is abutted against the inner wall of the input port 31, so that the material can be input into the input port 31.

[0034] Since the extension tube 21 of one connector 2 abuts against the blocking end 30 and the extension tube 21 of the other connector 2 extends into the input port 31 , the spherical valve core 3 can be restricted from rotating around the axis of the rotating shaft 33 , thereby improving the stability of the spherical valve core 3 .

[0035] When the direction of the spherical valve core 3 needs to be changed, the connector 2 needs to be rotated to disengage the extension tube 21 from the spherical valve core 3 , so as to prevent the extension tube 21 from affecting the rotation of the spherical valve core 3 .

[0036] In order to enhance the sealing performance between the extension tube 21 and the blocking end 30, in this embodiment, Figure 2 and Figure 3 As shown, the blocking end 30 is provided with an inwardly recessed embedding groove 35, wherein the embedding groove 35 is annular and coaxial with the output port 32, and a second sealing ring 5 is installed in the embedding groove 35. Figure 5 As shown, the end of the extension tube 21 is provided with a first closed end surface 211 , and the first closed end surface 211 abuts against the second sealing ring 5 to guide the material output from the output port 32 to smoothly enter the interior of the extension tube 21 .

[0037] A chamfer is provided at the edge of the first closed end face 211, and the chamfer here is consistent with the inclination angle of the side edge of the longitudinal section of the input port 31, and the chamfer is defined as the second closed end face 212, wherein the first sealing ring 4 is fixedly installed on the second closed end face 212. At this time, after the extension tube 21 of the connector 2 extends to the inside of the input port 31, the first sealing ring 4 abuts against the inner wall of the input port 31, thereby smoothly transferring the material in the connector 2 to the input port 31, reducing the risk of the material entering the gap between the spherical valve core 3 and the valve cavity 10, preventing material leakage, and improving the sealing of the interactive cavity.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
