Description

Technical Field

[0001] The present invention is applied to the technical field of homogenizing valve cores, and particularly relates to a homogenizing valve Z-type valve core. Background Art

[0002] Homogenizers are mainly used for tissue dispersion in the field of biotechnology, sample preparation in the field of medicine, enzyme treatment in the food industry, detection of pesticide residues and veterinary drug residues in food, as well as in the pharmaceutical industry, cosmetics industry, paint industry and petrochemical industry. High-pressure homogenizers allow liquid to flow through the gap between the valve core base and the cylindrical valve core of the homogenizing valve under high pressure, and use the smaller gap between the valve core base and the cylindrical valve core to shear the flowing liquid, so that the material is impacted onto the metal ring to generate a strong impact force and the cavitation explosion force generated by the sudden drop and rise of static pressure, etc., to process the original coarse emulsion into fine emulsion. The main components of the existing ultra-high pressure homogenizing valve are composed of a valve core base, a valve core and an impact ring. When working, ultra-high pressure liquid or material (which can be an emulsion or suspension mixed with solid particles) enters from the center hole of the valve core base, is forced to forcefully squeeze out of the mating surface, and collides with the impact ring to complete the shearing and impact crushing process of the material. The sheared and impacted material flows out from the gap between the impact ring and the valve core, completing the homogenization or crushing process and making the material reach a nanometer particle size. When the pressure is too high, the flow rate of this homogenizing valve is unstable, which easily causes cracks and collapses in the valve core base, and the service life is short. If a homogenizing valve Z-type valve core with a simple structure, stable flow rate, the ability to fully crush materials and perform secondary collisions on materials in different flow directions, and higher crushing efficiency can be designed, the above problems can be solved. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a Z-type valve core of a homogenizing valve with a simple structure, stable flow rate, the ability to fully crush materials and perform secondary collision of materials in different flow directions, and higher crushing efficiency.

[0004] The technical solution adopted by the present invention is: the present invention includes a valve core base and a valve core, a discharge channel is arranged in the middle of the valve core base, a plurality of crushing channels are arranged on the crushing side of the valve core, one end of the plurality of crushing channels are connected and conducted, the discharge channel cooperates with the connection of the plurality of crushing channels, a plurality of feed channels are arranged inside the valve core, the discharge ends of the plurality of feed channels are respectively connected and conducted with the other ends of the plurality of crushing channels, and the external fluid cooperates with the crushing channel through the plurality of feed channels.

[0005] Furthermore, a plurality of the feed channels are bent toward the middle of the feed end of the valve core and the bending angles of the plurality of the feed channels are the same.

[0006] Furthermore, four groups of the crushing channels are arranged on one side of the valve core, the angle between adjacent crushing channels is 90 degrees, and the discharge ends of the four groups of feed channels are respectively connected to the feed ends of the four groups of crushing channels.

[0007] Furthermore, the cross-sectional diameter of the feed end of the discharge channel is greater than the length of the connection line between any connection points of the four groups of crushing channels.

[0008] Furthermore, the extending direction of the feed end of the discharge channel is perpendicular to the plane of the broken side of the valve core.

[0009] Furthermore, the feed ends of the four groups of feed channels are evenly distributed in the middle of the other side of the valve core.

[0010] Furthermore, the valve core base and the valve core are both configured as cylindrical structures, and the valve core base is flush with the outer wall of the valve core.

[0011] Furthermore, the outer wall of the valve core base and the outer wall of the valve core are in contact with the inner wall of the external homogenizer.

[0012] Furthermore, the feed ends of some of the feed channels cooperate with the feed ends of the external homogenizers, and the discharge ends of the discharge channels cooperate with the discharge ends of the external homogenizers.

[0013] The beneficial effects of the present invention are as follows: the valve core base and the valve core are made of diamond material, which has high hardness, can meet the application scenarios of ultra-high pressure liquids and materials, and have a longer service life. The fluid enters from the feed ends of the deflection channels, and collides and crushes through the deflection points between the deflection channels and the crushing grooves. The materials that have completed the preliminary crushing enter the connection of the crushing grooves, and the materials in all directions collide with each other to complete the secondary crushing, which is more complete. The crushed products then flow out through the through holes. The angles between adjacent crushing grooves are 90 degrees, which can ensure that the materials can collide more stably when entering the connection, and the deflection angles of the deflection channels and the crushing grooves are the same, which can ensure that the material flow rates between the deflection channels and the crushing grooves are the same, so that the overall force of the valve core is more uniform and the service life is longer.

DETAILED DESCRIPTION

[0015] like Figures 1 to 6 As shown, in this embodiment, the present invention includes a valve core base 1 and a valve core 2, wherein a discharge channel 3 is provided in the middle of the valve core base 1, and a plurality of crushing channels 4 are provided on the crushing side of the valve core 2, and one end of the plurality of crushing channels 4 is connected and conducted, and the discharge channel 3 cooperates with the connection of the plurality of crushing channels 4, and a plurality of feed channels 5 are provided inside the valve core 2, and the discharge ends of the plurality of feed channels 5 are respectively connected and conducted with the other ends of the plurality of crushing channels 4, and the external fluid cooperates with the crushing channels 4 through the plurality of feed channels 5. It can be seen that the fluid enters from the feed ends of the plurality of feed channels 5, collides and crushes through the deflection point between the feed channel 5 and the crushing channel 4, and the material that has completed the preliminary crushing enters the connection of the four groups of crushing channels 4, and the materials in all directions collide with each other to complete the secondary crushing, so that the crushing is more complete, and the crushed product flows out through the through hole.

[0016] like Figure 2 As shown, in this embodiment, several of the feed channels 5 are deflected toward the middle of the feed end of the valve core 2 and the deflection angles of several of the feed channels 5 are the same. It can be seen that the same deflection angles of several of the feed channels 5 result in equal forces during the homogenization process, which prolongs the service life of the valve core.

[0017] like Figure 2 and Figure 3 As shown, in this embodiment, four groups of crushing channels 4 are arranged on one side of the valve core 2, the angle between adjacent crushing channels 4 is 90 degrees, and the discharge ends of the four groups of feed channels 5 are respectively connected to the feed ends of the four groups of crushing channels 4. It can be seen that the angle of 90 degrees between adjacent crushing channels 4 can ensure that the fluid entering the crushing channel 4 from the feed channel 5 can more fully collide with each other when reaching the connection of the four groups of crushing channels 4.

[0018] like Figure 4 As shown, in this embodiment, the cross-sectional diameter of the feed end of the discharge channel 3 is greater than the length of the line between any connection points of the four groups of crushing channels 4. It can be seen that due to the relatively large fluid pressure of the four groups of crushing channels 4, the diameter of the discharge channel 3 is larger than the flow space at the connection points of the four groups of crushing channels 4, so that the fluids in the four groups of crushing channels 4 can all flow into the discharge channel 3 after mutual collision, preventing accumulation caused by excessive pressure after collision, and causing the valve core 2 or the valve core base 1 to crack and collapse due to excessive flow rate of the fluid flowing out of the discharge channel 3.

[0019] like Figure 2As shown, in this embodiment, the extending direction of the feed end of the discharge channel 3 is perpendicular to the plane of the crushing side of the valve core 2. It can be seen that the discharge channel 3 is perpendicular to the plane of one side of the valve core 2, which can ensure that the flow rate of the four groups of crushing channels 4 entering the through hole is the same, so that the overall force of the valve core base 1 is more uniform.

[0020] like Figure 3 and Figure 5 As shown, in this embodiment, the feed ends of the four groups of feed channels 5 are evenly distributed in the middle of the other side of the valve core 2. It can be seen that the deflection angles of the four groups of feed channels 5 are the same, so that the flow velocity and collision force of the fluid entering the deflection between the feed channel 5 and the crushing channel 4 are the same.

[0021] like Figures 1 to 3 As shown, in this embodiment, the valve core base 1 and the valve core 2 are both configured as cylindrical structures, and the outer walls of the valve core base 1 and the valve core 2 are flush. It can be seen that the valve core base 1 and the valve core 2 can be integrally formed or separately designed, and the flush outer walls of the valve core base 1 and the valve core 2 can ensure that when the valve core 2 and the valve core base 1 are installed in the homogenizer, no gap will be generated to cause the material to flow out of the gap, and the sealing performance is stronger.

[0022] like Figures 1 to 3 As shown, in this embodiment, the outer wall of the valve core base 1 and the outer wall of the valve core 2 fit with the inner wall of the external homogenizer. It can be seen that the valve core base 1 and the valve core 2 are both cylindrical in design, which can ensure that no local gaps are generated during the installation process and can ensure that they fit with the inner wall of the homogenizer to form a sealing surface.

[0023] like Figure 1 to Figure 2 As shown, in this embodiment, the feed ends of several feed channels 5 cooperate with the feed ends of the external homogenizer, and the discharge ends of the discharge channels 3 cooperate with the discharge ends of the external homogenizer. It can be seen that the material enters from the four groups of feed channels 5, passes through the four groups of crushing channels 4, and then flows out from the discharge ends of the discharge channels 3. Multi-channel collision leads to better crushing effect.

[0024] The working principle of the present invention is as follows: before starting the equipment, the valve core base 1 and the valve core 2 are connected and installed in an external homogenizer. When the equipment is started, the fluid material enters from the feed end of the four groups of feed channels 5 on one side of the valve core 2, and the fluid collides through the deflection ends of the four groups of crushing channels 4. The fluid material that has completed the initial collision flows into the middle of the valve core 2. The fluids in four directions contact each other at the connection of the four groups of crushing channels 4 and undergo a secondary collision. The material that has completed the collision flows out from the discharge end of the valve core base 1 through the discharge channel 3, completing the homogenization or crushing of the material.

[0025] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
