[0023] Reference Figures 1 to 6 The multidimensional jet collision valve structure of the first aspect of this application includes a valve core 100 and a valve seat 200. The valve core 100 is provided with a plurality of feed holes 110, and the valve seat 200 is provided with a discharge hole 210. A collision cavity 300 is formed at the connection between the valve core 100 and the valve seat 200, and the collision cavity 300 connects the discharge hole 210 and the plurality of feed holes 110. At least three micro-jet channels 330 are defined within the collision cavity 300. The plurality of micro-jet channels 330 are evenly spaced around the outer periphery of the discharge hole 210, and the axes of the plurality of micro-jet channels 330 intersect at the center position of the collision cavity 300. The discharge hole 210 is aligned with the center position of the collision cavity 300. (Refer to...) Figure 1 As shown, the material enters the collision chamber 300 through the feed port 110, and after being crushed by mutual collision at the center of the collision chamber 300 through multiple micro-jet channels 330, it is discharged through the discharge port 210. The multi-dimensional jet collision valve structure of this application only includes a valve core 100 and a valve seat 200, and only has a feed port 110 and a discharge port 210. The collision chamber 300 only has multiple micro-jet channels 330. The structure is simple and the manufacturing and maintenance costs are low.

[0024] In the embodiments of this application, three or more microjet channels are preferably used, as can be referred to Figure 3 , Figure 4 The example shown has four channels, but it can also be configured with five, six, seven, etc. Generally speaking, the number of micro-jet channels 330 can be reasonably set according to the volume of the collision chamber 300 and the characteristics of the material, etc., and is not specifically limited in this embodiment. Three or more micro-jet channels 330 can generate multi-dimensional and multi-angle collisions when materials collide, thereby increasing the crushing effect of the material.

[0025] In the embodiments of this application, the ends of the feed hole 110 and / or the discharge hole 210 are chamfered. Preferably, both the ends of the feed hole 110 and the discharge hole 210 are chamfered. More preferably, the end of the feed hole 110 facing the material inlet is chamfered to facilitate rapid material entry and reduce the probability of material cutting the edge of the feed hole 110. More preferably, the end of the discharge hole 210 facing the valve core 100 is chamfered to facilitate rapid material outflow and reduce the probability of material cutting the edge of the discharge hole 210.

[0026] In the embodiments of this application, the cross-sectional shape of the feed hole 110 is one or more of a circle, an ellipse, and a polygon; and / or, the cross-sectional shape of the discharge hole 210 is one of a circle, an ellipse, and a polygon. Specifically, the aperture and cross-sectional shape of the feed hole 110 and the discharge hole 210 can be specifically set according to actual needs, and are not limited in this embodiment. For example, the multiple feed holes 110 can all be set to a circle, an ellipse, or a polygon, or some can be set to a circle, some to an ellipse, and / or a polygon, etc.; the cross-sectional areas of the multiple feed holes 110 can be set to be equal or unequal, preferably equal, in order to reduce manufacturing costs. The cross-sectional area of ​​the discharge hole 210 can gradually increase or decrease or remain unchanged along its axis.

[0027] Accordingly, the cross-sectional areas of the multiple micro-channels 330 in this embodiment are equal or unequal, and / or the cross-sectional shapes of the multiple micro-channels 330 are the same or different. Specifically, the cross-sectional areas and cross-sectional shapes of the multiple micro-channels 330 are preferably set to be equal and the same to reduce manufacturing costs. However, the cross-sectional areas of the multiple micro-channels 330 can also be set to be unequal, or the cross-sectional shapes of the multiple micro-channels 330 can be set to be different, depending on the actual situation. This embodiment does not impose any limitations on this.

[0028] It is conceivable that the axial lengths of the multiple micro-jet channels 330 can also be set to be equal or unequal according to the actual situation, and are not limited in this embodiment.

[0029] In the embodiments of this application, the valve core 100 and the valve seat 200 are connected as an integral structure or by fasteners. The valve core 100 and valve seat 200 connected as an integral structure have the best stability. The valve core 100 and valve seat 200 connected by fasteners such as bolts and clips are easy to manufacture and facilitate the reduction of equipment costs and equipment maintenance costs.

[0030] In the embodiments of this application, the collision cavity 300 can be formed in various ways, such as the following: Option 1: The valve seat 200 has a groove 310, within which multiple protrusions 320 are provided, forming micro-jet channels 330 between adjacent protrusions 320; the valve core 100 is sealed to the valve seat 200, and the end face of the valve core 100 mates with the groove 310 to form a collision cavity 300. For details, refer to... Figure 2 , Figure 3 As shown, the valve core 100 is provided with multiple feed holes 110, and the groove 310 and the protrusion 320 are both provided on the valve seat 200. After the valve core 100 and the valve seat 200 are sealed together, the multiple feed holes 110 are connected to the groove 310.

[0031] It is conceivable that the valve core 100 may have a groove 310, and multiple protrusions 320 may be provided in the groove 310, with micro-jet channels 330 formed between adjacent protrusions 320; the valve core 100 may be sealed to the valve seat 200, and the end face of the valve seat 200 may cooperate with the groove 310 to form a collision cavity 300; multiple feed holes 110 of the valve core 100 may be connected to the groove 310, and the valve seat 200 may only have a discharge hole 210, which is preferably coaxial with the valve seat 200.

[0032] Option 2: The valve seat 200 has a groove 310, and the valve core 100 has a protrusion 320. The valve core 100 and the valve seat 200 are sealed together. The protrusion 320 is in contact with the bottom of the groove 310, and a micro-jet channel 330 is formed between adjacent protrusions 320. Specifically, the difference between Option 2 and Option 1 is that the groove 310 and protrusion 320 in Option 1 are respectively set on the valve core 100 and the valve seat 200. That is, the valve core 100 has multiple feed holes 110 and multiple protrusions 320, and the valve seat 200 has multiple discharge holes 210 and grooves 310.

[0033] It is conceivable that the valve seat 200 could have a groove 310, and the valve core 100 could have a protrusion 320. The valve core 100 and the valve seat 200 could be sealed together, with the protrusion 320 abutting against the bottom of the groove 310, and a micro-jet channel 330 formed between adjacent protrusions 320; that is, referring to... Figure 5 As shown, the valve core 100 is provided with multiple feed holes 110 and grooves 310, as shown in the reference. Figure 6 As shown, the valve seat 200 is provided with a discharge hole 210 and multiple protrusions 320, which are evenly spaced around the outer periphery of the discharge hole 210.

[0034] Option 3: Multiple slotted grooves 340 are spaced apart on the outer periphery of the discharge port 210, each corresponding to one of the feed ports 110. The valve core 100 is sealed to the valve seat 200, and the slotted grooves 340 mate with the end face of the valve core 100 to form a micro-jet channel 330. Specifically, the structure of the valve core 100 in Option 3 is as follows: Figure 2 As shown, the valve core 100 is provided with only a plurality of feed holes 110, and the valve seat 200 has the following structure. Figure 4 As shown, the valve seat 200 is provided with a discharge hole 210 and a plurality of strip grooves 340, and the plurality of feed holes 110 are preferably aligned with the ends of the plurality of strip grooves 340.

[0035] It is conceivable that in Scheme 3, the strip groove 340 could also be set on the valve core 100, the valve seat 200 could only have a discharge hole 210, and multiple feed holes 110 set on the valve core 100 could be evenly spaced around the outer periphery of the strip groove 340. However, it should be noted that since the discharge hole 210 is set on the valve seat 200, when the strip groove 340 is set on the valve core 100, the valve core 100 must also have a central groove at the position corresponding to the discharge hole 210 to communicate with the multiple strip grooves 340.

[0036] Reference Figure 7 As shown, the cavity encapsulation structure of the second aspect embodiment of this application includes a housing 400, which has an input port 410 and an output port 420. The aforementioned multidimensional jet collision valve structure is installed between the input port 410 and the output port 420. The housing 400 is hollowed out to form a circulating heat dissipation structure to cool the multidimensional jet collision valve structure, thereby preventing overheating and extending its service life. Since the cavity encapsulation structure includes the aforementioned multidimensional jet collision valve structure, it also has at least all the beneficial effects of the multidimensional jet collision valve structure, which will not be elaborated here.
