High shear collision type homogeneous valve

technical field

The utility model relates to the technical field of homogenizers, in particular to a homogenizing valve in the homogenizer.

Background technique

The main principle of the homogenizer in the existing technology is to make the material produce strong shear, impact and cavitation under high pressure when the material passes through the working valve, so that the liquid material or the solid particle with the liquid as the carrier can be super-charged. Miniaturization. The main functions are to improve the uniformity and stability of the product, increase the shelf life, reduce the reaction time, change the consistency of the product, improve the taste and color of the product, etc. It can be used in the food and beverage industry, cosmetics industry, chemical industry, pharmaceutical industry, bioengineering technology etc.

The collision type homogenizing valve is the core structure in the high-pressure homogenizer. The shearing effect of the current collision type homogenizing valve is not enough, which will affect the homogenization effect.

Utility model content

In order to overcome the shortcomings of the above-mentioned prior art, the purpose of this utility model is to provide a high-shear collision type homogenizing valve, which increases the shearing force and shearing time of the material in the homogenizing chamber, so that the homogenizing effect better.

In order to solve the above problems, the utility model adopts the following technical solutions: a high shear force collision type homogeneous valve, including a valve stem, an impact ring and a valve seat; there is a flow channel in the valve seat; its feature is: There are four flow channels, and each flow channel is spiral; the spiral direction of the four flow channels is the same, and the four flow channels are evenly arranged in the valve seat around the center axis of the valve seat; on the inner wall of the four flow channels, the impact ring Micro-textures are provided on the inner wall.

As a further technical solution of the present utility model: in each flow channel, the micro-texture monomers surround the inner wall of the flow channel for a week, the micro-texture monomers are in the shape of grooves, and several micro-texture monomers are arranged in the axial direction of the inner wall, etc. distance arrangement.

Further: the spacing between the micro-textured monomers in the four flow channels is equal.

Further: the cross-section of the micro-textured monomer is rectangular.

Further: the size of the micro-texture is micron-scale.

The beneficial effect of the utility model is: the high shearing force collision type homogenizing valve increases the shearing force and shearing time of the material in the homogenizing cavity, so that the homogenizing effect is better.

detailed description

As shown in Figures 1 and 2, the high shear collision type homogeneous valve includes a valve stem 1, an impact ring 2 and a valve seat 4; the valve seat 4 has a flow channel inside.

As shown in Figures 3, 4, and 5, there are four flow passages in the valve seat 4 of the homogeneous valve, and each flow passage 3 is in a spiral shape; the spiral directions of the four flow passages 3 are the same, and the four flow passages 3 wrap around The center axis of the valve seat is evenly arranged in the valve seat 4; the inner walls of the four flow channels 3 and the inner wall of the impact ring 2 are provided with micro-textures, which are respectively recorded as the channel micro-texture 7 and the impact ring micro-texture. Structure 8. In this embodiment, the four flow channels 3 and the cavity surrounded by the base 4 , the impact ring 2 and the valve stem 1 constitute the homogeneous cavity 6 of the homogeneous valve.

In this embodiment, in each flow channel 3, each micro-texture monomer of the flow channel micro-texture 7 surrounds the inner wall of the flow channel for a week, that is, a single micro-texture is ring-shaped; in addition, the micro-texture monomer is a groove Groove-shaped, several micro-textured monomers are arranged equidistantly in the axial direction of the inner wall of the flow channel, as shown in Figure 6. In this embodiment, the distances between the micro-textured monomers in the four channels are equal. In addition, the cross-section of each micro-texture monomer of the channel micro-texture is rectangular.

In the impact ring 2, each micro-texture monomer of the impact ring micro-texture 8 circles around the inner wall of the impact ring, that is, each single micro-texture is ring-shaped; in addition, the micro-texture monomer is also groove-shaped, and several micro-textures The texture monomers are arranged equidistantly in the axial direction of the inner wall of the impact ring, as shown in Figure 7. In addition, the cross-section of each micro-texture monomer of the impact ring micro-texture is also rectangular.

The sizes of the micro-textures in this embodiment are all micron-scale.

When the homogenizing valve is working, the material enters from the lower end of the valve seat 4, and homogeneous treatment occurs in the homogenizing chamber 6, that is, the four flow channels 3, and then reaches the gap between the valve stem 1 and the impact ring 2, and finally flows through the fluid outlet. 5 flows out of the homogenizing valve, as shown in Figure 5.

The micro-texture 7 of the flow channel increases the friction coefficient of the homogeneous cavity wall and increases the shear force in the near-wall area of the turbulent flow, thereby increasing the probability that the particles in the material are destroyed in the near-wall area.

The micro-texture 8 of the impact ring further ensures that the material flowing out of the homogenizing valve is further frictionally damaged to ensure the effect of homogenization.

The embodiments of the present utility model have been described in detail above, but the content described is only a preferred embodiment of the present utility model, and cannot be considered as limiting the implementation scope of the present utility model.

There are other forms of micro-texture arrangement, and the shape of the micro-texture monomer is not limited to a rectangle. It is just that the arrangement of the micro-textures and the shape of the micro-texture monomers in the above embodiments can better ensure the homogeneity effect, and the preparation process is simpler and easier to realize.
