In the homogenizing process, because the buoyancy of the fat ball is very large, the fat ball before homogenizing is basically concentrated above the dairy product solution, so that the homogenization of the valve core 1 is partially uneven during homogenizing, the homogenizing valve is an article with high loss, if the homogenization is uneven, the loss of different parts of the valve core 1 is different, and the service life of the whole valve body is shortened.

The existing common homogenizing valves are all of the collision type, if only depending on the cavitation effect and collision at the gap between the valve core 1 and the valve seat 2, the shearing effect of the whole body on the fat ball is not particularly good, and the design has large loss on the whole valve body, does not play a better effect under the condition of large loss, and is too high for cost consumption.

The homogeneity valve will guarantee that case 1 just can carry out the homogeneity effectively with disk seat 2 just right when using, and the hydraulic system who adopts in practice supports case 1 to just having accomplished on disk seat 2, and this just can't guarantee after case 1 has taken place the offset that case 1 aligns with the center of disk seat 2, and the gap when follow-up homogeneity like this will cause inhomogeneous, and the homogeneity effect can descend, and the damage to case 1 also can be very big.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, a homogenizing valve of a high-pressure homogenizer includes a valve core 1, one side of the valve core 1 is supported against one side of a valve seat 2 through a hydraulic system, an impact ring 3 is movably sleeved on the valve core 1 and the valve seat 2 in a supporting manner, two positioning blocks 102 are symmetrically and fixedly installed on the outer side of one end of the valve core 1, two positioning grooves 301 are symmetrically formed on the inner side of the impact ring 3, a bearing 4 is fixedly installed in the valve seat 2, a spiral blade 5 is fixedly installed on the inner side of the bearing 4, and the outer side of the bearing 4 is fixed on the valve seat 2.

Wherein, one side of the valve core 1 is provided with a raised head 101, the joint of the raised head 101 and the valve core 1 is an inclined plane, the inner ring of the impact ring 3 close to one side of the valve seat 2 is designed into an inclined plane, and the inclined plane is parallel to the inclined plane designed by the valve core 1. The raised head 101 and the inclined plane are designed to be more beneficial to the impact of dairy product solution, the impact is already carried out on the fat ball particles at the position where the fat ball particles do not enter the gap between the valve core 1 and the valve seat 2, the subsequent impact shearing can be regarded as a buffering effect, the number of large-particle fat balls entering the gap is reduced, and the more permanent use of the homogenizing valve is facilitated. The inclined plane on the impact ring 3 corresponds with the inclined plane on the valve core 1 in parallel, so that the fat ball impacting the inclined plane of the valve core 1 can impact the inclined plane on the impact ring 3 again under the reflecting effect, multiple times of impact is carried out, the integral homogenizing effect is improved, and the inclined plane on the impact ring 3 can ensure that the fat ball particles reflected by the valve core 1 are impacted and reflected to the outside of the valve core 1 and cannot be accumulated in the valve seat 2.

The positioning block 102 is adapted to the positioning groove 301, and both ends of the positioning block 102 contacting the positioning groove 301 are corner edges. The locating piece 102 is designed into the edge and can be conveniently clamped into the locating groove 301, and the locating groove 301 is structurally designed to be matched with the locating piece 102, so that the locating groove 301 can be firmly fixed after being completely clamped with the locating piece 102, and the edge and corner edges can not generate large resistance to the liquid after homogenization.

Wherein, the inside of case 1 is seted up cyclic condensation hole 103, and the condensate import and export all is in one side. The condensation hole 103 is formed, so that the valve core 1 can be conveniently cooled, the service life of the valve core 1 is not influenced by overhigh temperature due to homogenization, and the use safety is ensured.

Wherein, the side edge of the spiral blade 5 is a sharp edge. The spiral blade 5 is designed to increase the effect of stirring and mixing, and the solution entering the valve seat 2 has great pressure, so that the spiral blade 5 can collide with fat balls in the solution, and the sharp side edge is more beneficial to colliding and shearing the large fat balls into smaller particles.

Wherein, the top of the raised head 101 is a semicircle. The semicircular design reduces the resistance, and the fat ball can directly impact the inclined plane and the impact ring 3.

The working principle is that firstly, the installed homogenizing valve is firm and tight (only the positioning block 102 is aligned with the positioning groove 301 is ensured), when the homogenizer works, a dairy product solution enters the valve seat 2 under the pressure action of the plunger pump, the solution can firstly impact the spiral blade 5, the spiral blade 5 rotates to drive the solution in the whole valve seat 2 to be uniformly mixed (the fat balls can not float upwards in the top in a centralized way), under the action of the pressure, the solution can prop the valve core 1 and the valve seat 2 to form a small gap, the solution enters the outer side part of the valve core 1 through the gap, large-particle fat balls in the solution can generate a cavity effect at the gap to be dispersed into smaller particles, meanwhile, the fat balls impacting the inclined planes of the valve core 1 and the impact ring 3 can be sheared into smaller particles due to impact, when the homogenizing temperature of the valve core 1 is too high, condensate is cooled through the condensation hole 103, the normal work of the valve core is ensured, and the fat balls which completely pass through the homogenizing valve complete the homogenizing process for subsequent production and processing.
