Description

Technical Field

[0001] The present application relates to the field of homogenizing valves, and in particular to a collision-type homogenizing valve structure. Background Art

[0002] The homogenizing valve is the main component in the homogenizer used to homogenize and refine the liquid to achieve the effect of homogenizing and refining the material. It is widely used in the production and processing of emulsions in the food, dairy, beverage, cosmetics and other industries.

[0003] like Figure 8 As shown, the existing homogenizing valve includes a valve body 1, a valve seat 2 and a valve core 3 installed in the valve body 1, wherein the valve core 3 is continuously pressed against the valve surface of the valve seat 2 by the force of the external push rod 10. When working, the material enters the valve seat 2 from the material inlet in a high-pressure fluid state, and then the high-pressure material pushes the valve core 3 to overflow from the contact surface between the valve core 3 and the valve seat 2 at a high speed, and then enters the annular inner cavity 20 of the valve body 1, and collides with the inner wall of the annular inner cavity 20 to achieve the material collision effect and cavitation effect, and finally the homogenized high-pressure material flows out from the material outlet.

[0004] The greater the thrust applied by the push rod 10, the higher the material pressure required to push open the valve core 3, and the faster the flow rate of the material overflowing from the contact surface between the valve core 3 and the valve seat 2, the better the corresponding shear effect, collision effect, and cavitation effect, so the homogenization effect is also better.

[0005] As the material flow rate increases, the impact and wear on the wall of the annular cavity increases, which results in a corresponding weakening of the homogenization effect. Summary of the invention

[0006] In order to reduce the impact and wear of high-pressure materials on parts and increase the service life of parts, the present application provides a collision-type homogenizing valve structure.

[0007] The present application provides a collision-type homogenizing valve structure, which adopts the following technical solution:

[0008] A collision type homogenizing valve structure comprises a valve body, a valve seat and a valve core, wherein the valve body is provided with a material inlet hole, a material discharge hole and a transfer chamber, wherein the valve seat is arranged in the valve body, and the valve seat is penetrated by a homogenizing hole, one port of the homogenizing hole is communicated with the material discharge hole, the other port of the homogenizing hole is located in the transfer chamber, and the outlet of the material inlet hole is communicated with the transfer chamber; the valve core is movably connected with the valve body, one end of the valve core is a force-bearing end, and the other end of the valve core is an abutting end, and the abutting end is used to abut with the valve surface of the valve seat away from the material discharge hole, and the abutting end of the valve core is provided with a force-applying surface, and the vertical direction of the force-applying surface has an acute angle or is parallel to the sliding direction of the valve core.

[0009] By adopting the above technical solution, during operation, high-pressure materials enter the transfer chamber from the material inlet hole, and the pressure in the transfer chamber is equal. Therefore, the pressure or pressure component applied by the high-pressure materials on the force-applying surface will force the valve core to leave the valve seat. At this time, the high-pressure materials in the transfer chamber will overflow from the valve face and valve core ring of the valve seat into the homogenizing hole at high speed, and rush into the center of the homogenizing hole. Multiple high-pressure materials will convect and collide with each other at the center of the homogenizing hole, thereby achieving the effect of homogenizing and crushing the materials.

[0010] In this way, the original collision with the rigid structure (such as the annular cavity wall in the prior art) is changed to the collision of multiple streams of high-pressure materials, so as to directly reduce the collision and wear on the valve structure, that is, the homogenization stability is stronger.

[0011] In addition, in the form of collision, the collision kinetic energy is the superposition of the kinetic energy of multiple high-pressure materials. Compared with the existing collision mode, the collision kinetic energy of this technical solution is greater, so the homogenization effect will be greatly improved.

[0012] Optionally, a first chamfer is provided at an inner edge of a valve surface of the valve seat abutting against the abutting end.

[0013] By adopting the above technical solution, when the high-pressure material in the transfer chamber overflows from the valve surface of the valve seat into the homogenizing hole at high speed, the first chamfer will guide the high-pressure material to diffuse on the longitudinal section of the valve seat, that is, the spraying area is increased and controllable, so that the collision area of ​​multiple streams of high-pressure materials is increased, and the overlap of the collision area is higher, thereby improving the collision efficiency and collision effect of multiple streams of high-pressure materials, thereby improving the homogenizing effect.

[0014] In addition, it also reduces the situation where individual strands of high-pressure materials directly hit the inner wall of the valve seat without colliding with other strands of high-pressure materials, that is, it also reduces the wear of the inner wall of the valve seat.

[0015] Optionally, a mounting groove for matching with the valve seat is provided in the valve body, and the outer diameter of the valve seat gradually decreases in a direction away from the valve core.

[0016] By adopting the above technical solution, when the valve core is pressed against the valve seat, due to the conical structure of the valve seat, the valve seat is more tightly embedded in the installation groove, so that the sealing between the valve seat and the installation groove is greatly enhanced.

[0017] And it has the property of centering, which makes the coaxiality between the valve seat and the valve core better, and the overflow effect of high-pressure materials is better.

[0018] Optionally, the valve body is sequentially provided with a matching hole and a mounting hole along the direction of the material discharge hole, a shaft sealing sleeve is installed in the mounting hole, the valve core is sequentially passed through the inner cavity of the shaft sealing sleeve and the matching hole to enter the transfer cavity, the maximum outer diameter of the valve seat is less than or equal to the mounting hole, and the inner diameter of the valve seat is smaller than the aperture of the material discharge hole.

[0019] By adopting the above technical solution, the material discharge hole, the matching hole and the mounting hole are all located on the same axis. Therefore, when the valve seat, the valve core or the shaft seal sleeve needs to be replaced, the external push rod can be removed first, and then a tool, such as a push rod, is used to push one end of the valve seat toward the mounting hole, thereby ejecting the valve seat, the valve core and the shaft seal sleeve from the mounting hole on the valve body together. In this way, disassembly is more convenient.

[0020] Optionally, the force-applying surface includes a second chamfer, and the second chamfer is arranged at the outer edge of the abutting end.

[0021] By adopting the above technical solution, the high-pressure material in the transfer chamber will exert pressure on the second chamfer, and the component force of the pressure will force the valve core to move away from the valve seat. In this way, the pressure required for the high-pressure material to push open the valve core will be much greater than the pressure required for the existing pushing method, thereby increasing the upper limit of the pressure applied to the high-pressure material in disguise, that is, the sprayable pressure of the high-pressure material is greatly improved, thereby greatly improving the homogenization effect.

[0022] Optionally, the end surface of the abutting end is divided into an exposed surface and an abutting surface from outside to inside, wherein the abutting surface is a surface that fits with the valve surface of the valve seat, and the force-applying surface includes the exposed surface.

[0023] By adopting the above technical solution, the high-pressure material in the transfer chamber will exert pressure on the exposed surface, and the component force of the pressure will force the valve core to move away from the valve seat, thereby achieving the purpose of pushing the valve core open.

[0024] Optionally, the central axis of the material inlet hole is perpendicular to the central axis of the valve core.

[0025] Compared with the existing method of directly pushing the valve core with materials, the above technical solution changes the relative relationship between the flow direction of the high-pressure material and the valve core. The pressure of the high-pressure material is perpendicular to the sliding direction of the valve core, thereby increasing the difficulty of the high-pressure material to push open the valve core. The high-pressure material can only push the valve core through a force-applying surface with a smaller area. In this way, the pressure required for the high-pressure material to push open the valve core will be much greater than the pressure required by the existing pushing method, thereby increasing the upper limit of the pressure applied to the high-pressure material in disguise, that is, the sprayable pressure of the high-pressure material is greatly improved, thereby greatly improving the homogenization effect.

[0026] Optionally, the cavity wall of the transfer cavity is provided with an annular overflow gap arranged around the valve core, and the valve body is provided with a matching hole for the valve core to pass through, the matching hole is connected with the overflow gap, and a first sealing ring and a second sealing ring arranged in sequence along the direction away from the material discharge hole are installed in the matching hole, and a V-shaped groove is provided on the end surface of the first sealing ring facing the overflow gap, and an annular V-shaped spring piece is installed in the V-shaped groove, and the opening of the V-shaped spring piece faces the overflow gap.

[0027] By adopting the above technical solution, the high-pressure material in the transfer chamber will enter the V-shaped groove through the overflow gap, forcing the V-shaped spring sheet to expand, thereby driving the first sealing ring to expand radially and move axially to squeeze the second sealing ring, thereby increasing the radial and axial sealing effects.

[0028] Optionally, the valve body is provided with a mounting groove for adapting to the valve seat, a step groove is provided between the mounting groove and the material discharge hole, an elastic support member is provided on the step groove, a guide member is provided on the elastic support member, and the guide member is located in the homogenizing hole of the valve seat; the guide member includes a plurality of quadrangular prisms, each of the quadrangular prisms is evenly discharged around the axial circumference of the homogenizing hole, a guide gap is formed between adjacent quadrangular prisms, the edges of the quadrangular prisms face the outer diameter of the valve seat, the upper ends of the quadrangular prisms are commonly fixedly connected to an upper limit ring, the upper limit ring is located in the annular groove opened at the abutting end, and the lower ends of the quadrangular prisms are commonly fixedly connected to a lower limit ring, and the lower limit ring is rotatably connected to the elastic support member.

[0029] By adopting the above technical solution, when the high-pressure material in the transfer chamber overflows from the valve surface of the valve seat into the homogenizing hole at a high speed and converges and rushes into the center of the homogenizing hole, the multiple strands of high-pressure materials arranged in a ring are originally diffused, but are first guided by the quadrangular prism to pass through the guide gap and enter the center of the homogenizing hole. At this time, the trajectory of the high-pressure material is clearer, the collision accuracy is higher, and the homogenization effect is better.

[0030] In addition, through the rotation cooperation between the lower limit ring and the elastic support member, the position of the quadrangular prism can be changed around the center of the homogenizing hole. In this way, when multiple streams of high-pressure materials hit the quadrangular prism, the quadrangular prism will be forced to rotate, and the quadrangular prism will rotate to a state where the impact force is balanced, thereby greatly reducing the damage to the quadrangular prism.

[0031] Moreover, when one stream of high-pressure material hits one of the tetrahedrons, the entire tetrahedron moves, causing the other tetrahedron to collide with the other stream of high-pressure material. It can be seen that the entire tetrahedron, as an intermediary structure, can transmit the impact force of multiple high-pressure materials, that is, it is essentially a collision between multiple streams of high-pressure materials, but through the use of the entire tetrahedron, the collision relationship between two streams of high-pressure materials that would not originally collide is reduced, thereby improving the collision uniformity and homogenization effect.

[0032] Furthermore, through the cooperation between the valve core and the upper limit ring, the valve core applies a downward force to the quadrangular prism, and the elastic support member applies an upward elastic force to the quadrangular prism, so as to jointly stably limit the quadrangular prism in the homogeneous hole.

[0033] Optionally, the elastic support rod includes a plurality of elastic arc rods radially arranged with the axis of the homogenizing hole as the center, one end of each of the arc rods is fixed, and the other end of the arc rod abuts against the step groove; a third limiting ring is commonly fixed to the middle part of each of the arc rods, the third limiting ring is coaxially arranged with the homogenizing hole, and the lower limiting ring is rotatably sleeved on the outer side of the third limiting ring.

[0034] By adopting the above technical solution, the arc rod can exert an upward force on the quadrangular prism to fix the quadrangular prism. The third limiting ring is set to limit the lower limiting ring to ensure that it remains coaxial with the homogenizing hole.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. Through various structural settings, the high-pressure material in the transfer chamber can push the valve core along the force-applying surface and overflow into the homogenizing hole from the valve surface of the valve seat at high speed. At this time, the annular high-pressure material rushes into the center of the homogenizing hole and convects and collides with each other to achieve the effect of homogenization and crushing. At the same time, the impact and wear of the material on the valve seat and valve core are greatly reduced, thereby also prolonging the service life of parts;

[0037] 2. By setting the relative positions of the material discharge hole, matching hole, mounting hole, valve seat and valve core, the valve seat, valve core and shaft seal sleeve can be ejected from the mounting hole on the valve body together, so that maintenance, disassembly and installation will be more convenient and quick;

[0038] 3. By changing the way or structure of the high-pressure material pushing open the valve core, the pressure required for the high-pressure material to push open the valve core is much greater than the pressure required by the existing pushing method, thereby increasing the upper limit of the pressure applied to the high-pressure material in disguise, that is, the sprayable pressure of the high-pressure material is greatly increased, thereby greatly improving the homogenization effect.

DETAILED DESCRIPTION

[0048] The following is combined with Figure 1-7 This application is described in further detail.

[0049] Example 1 of the present application discloses a collision-type homogenizing valve structure.

[0050] Reference Figure 1 The collision type homogenizing valve structure includes a valve body 1, a valve seat 2, a valve core 3 and a shaft sealing sleeve 4, wherein the valve body 1 is provided with a mounting hole 11, a matching hole 12, a transfer cavity 13, a mounting groove 16 and a material discharge hole 14 in sequence along its own central axis, and a material inlet hole 15 is provided on the other side of the valve body 1, and the material inlet hole 15 is connected with the transfer cavity 13; the material inlet hole 15 can be in the same direction as the central axis of the valve body 1, and can also be in a different direction from the central axis of the valve body 1. In this embodiment, the central axis of the material inlet hole 15 is perpendicular to the central axis of the valve body 1.

[0051] like Figure 2 As shown, the valve seat 2 is installed in the installation groove 16, and the outer diameter of the valve seat 2 gradually decreases in the direction away from the installation hole 11. In this embodiment, the valve seat 2 is conical, and the maximum outer diameter of the valve seat 2 is less than or equal to the inner diameter of the installation hole 11 and the shaft sealing sleeve 4. The inner diameter of the valve seat 2 is smaller than the aperture of the material discharge hole 14.

[0052] like Figure 2 , Figure 3As shown, the valve surface of the valve seat 2 away from the material discharge hole 14 is named the abutting valve surface 21. The abutting valve surface 21 is located in the transfer chamber 13, and in order to improve the force effect, the abutting valve surface 21 can also be located on the virtual extended path of the material inlet hole 15, that is, the high-pressure material in the material inlet hole 15 will contact the abutting valve surface 21 more directly.

[0053] The valve seat 2 is penetrated by a homogenizing hole 22, which is coaxially arranged with the material discharge hole 14. A third chamfer 24 is arranged at the outer edge of the abutting valve face 21, and a first chamfer 23 is arranged at the inner edge of the abutting valve face 21.

[0054] like Figure 1 As shown, the shaft sealing sleeve 4 is installed in the mounting hole 11. The shaft sealing sleeve 4 can be installed by interference fit or by limiting installation through an external end cover structure. The valve core 3 passes through the shaft sealing sleeve 4 and the matching hole 12 in sequence and enters the transfer cavity 13. A sealing assembly 5 is provided between the valve core 3 and the hole wall of the matching hole 12 to seal the gap between the transfer cavity 13 and the shaft sealing sleeve 4.

[0055] The valve core 3 can move relative to the valve body 1 along the central axis of the valve body 1. Specifically, one end of the valve core 3 is a force-bearing end 31, and the other end of the valve core 3 is an abutting end 32. The external push rod 10 can apply force to the force-bearing end 31 to force the abutting end 32 of the valve core 3 to be tightly pressed against the abutting valve surface 21 of the valve seat 2.

[0056] like Figure 3 As shown, the abutting end 32 of the valve core 3 is provided with a force-applying surface, and the vertical direction of the force-applying surface is at an acute angle or parallel to the sliding direction of the valve core 3. When the high-pressure material enters the transfer chamber 13 from the material inlet hole 15, the high-pressure material will apply a force to the valve core 3 through the force-applying surface to force the valve core 3 to move away from the valve seat 2.

[0057] Therefore, the force-applying surface can be simply the second chamfer 321 arranged on the outer edge of the abutting end 32, and the force-applying surface can also be simply the surface of the abutting end 32 that is not in contact with the abutting valve surface 21, that is, the end surface of the abutting end 32 is divided into an exposed surface 322 and an abutting surface 323 from the outside to the inside, wherein the abutting surface 323 is a surface in contact with the valve surface of the valve seat 2, and the exposed surface 322 is the force-applying surface, and the direction of the pressure applied by the high-pressure material on the exposed surface 322 is the same as the backward direction of the valve core 3, so as to force the valve core 3 to move away from the valve seat 2.

[0058] In this embodiment, the force-applying surface includes a second chamfer 321 and an exposed surface 322 .

[0059] like Figure 4As shown, the sealing assembly 5 can be a single sealing ring or a combination of multiple sealing rings. In this embodiment, the sealing assembly 5 includes a first sealing ring 51 and a second sealing ring 52. The first sealing ring 51 and the second sealing ring 52 are axially stacked in a direction away from the material discharge hole 14, and the second sealing ring 52 abuts against the shaft sealing sleeve 4; an overflow gap 17 is provided between the matching hole 12 and the transfer cavity 13, and a V-shaped groove 511 is provided on the end surface of the first sealing ring 51 facing the overflow gap 17, and an annular V-shaped spring piece 512 is installed in the V-shaped groove 511, and the opening of the V-shaped spring piece 512 faces the overflow gap 17.

[0060] The high-pressure material in the transfer chamber 13 will enter the V-shaped groove 511 through the overflow gap 17 to force the V-shaped spring piece 512 to expand, thereby driving the first sealing ring 51 to expand radially and move axially to squeeze the second sealing ring 52, thereby increasing the radial and axial sealing effects.

[0061] The implementation principle of the embodiment 1 is as follows: during operation, the high-pressure material enters the transfer chamber 13 from the material inlet hole 15, and the valve core 3 is pressed against the abutting valve surface 21 of the valve seat 2 by the external push rod 10. The pressure or pressure component force applied by the high-pressure material on the force-applying surface overcomes the force of the push rod 10 to force the valve core 3 to leave the valve seat 2. At this time, the high-pressure material in the transfer chamber 13 will overflow from the abutting valve surface 21 of the valve seat 2 into the homogenizing hole 22 at a high speed (refer to Figure 2 At this time, the high-pressure material along the annular direction of the valve core 3 will converge and rush into the center of the homogenizing hole 22, and multiple streams of high-pressure materials will convect and collide with each other at the center of the homogenizing hole 22, thereby achieving the effect of homogenizing and crushing the material.

[0062] In this way, the original collision with the rigid structure (such as the annular cavity wall in the prior art) is changed to the collision of multiple streams of high-pressure materials, so as to directly reduce the collision and wear on the valve structure, that is, the homogenization stability is stronger.

[0063] In addition, in the form of collision, the collision kinetic energy is the superposition of the kinetic energy of multiple high-pressure materials. Compared with the existing collision mode, the collision kinetic energy of this technical solution is greater, so the homogenization effect will be greatly improved.

[0064] Finally, when the valve seat 2, valve core 3 or shaft sealing sleeve 4 needs to be replaced, the external push rod 10 can be removed first, and then a tool, such as a push rod, can be used to push one end of the valve seat 2 toward the mounting hole 11, thereby pushing the valve seat 2, valve core 3 and shaft sealing sleeve 4 out of the mounting hole 11 on the valve body 1 together, so that disassembly is more convenient.

[0065] Example 2

[0066] The difference between Example 2 and Example 1 is that Figure 5As shown, a step groove 18 is provided between the installation groove 16 and the material discharge hole 14 . In other embodiments, a sealing ring may be placed in the step groove 18 .

[0067] like Figure 6 As shown, an elastic support member is provided on the step groove 18, and the elastic support rod includes a plurality of elastic arc rods 61. The arc rods 61 are made of stainless steel. Each arc rod 61 is radially arranged with the axis of the homogenizing hole 22 as the center. The proximal ends of the arc rods 61 are fixedly connected together, and the separated ends of the arc rods 61 abut against the step groove 18, that is, the entire elastic support member is supported on the step groove 18 in a claw shape, and a third limiting ring 62 is fixed to the middle part of each arc rod 61, and the third limiting ring 62 is coaxially arranged with the homogenizing hole 22.

[0068] like Figure 6 , Figure 7 As shown, a guide member is provided on the elastic support member, and the guide member is located in the homogenizing hole 22 of the valve seat 2. The guide member includes an upper limit ring 73, a lower limit ring 72 and a plurality of quadrangular prisms 71. The quadrangular prisms 71 are parallel to the axis of the homogenizing hole 22, and the number of the quadrangular prisms 71 is preferably an even number.

[0069] The quadrangular columns 71 are evenly arranged around the axial circumference of the homogenizing hole 22 , and a guide gap 75 is formed between adjacent quadrangular columns 71 . The edges of the quadrangular columns 71 face the outer diameter of the valve seat 2 , and the virtual outer diameter formed by the quadrangular columns 71 is greater than or equal to the aperture of the homogenizing hole 22 .

[0070] The lower ends of the quadrangular prisms 71 are fixedly connected together by a lower limiting ring 72 . The lower limiting ring 72 is rotatably sleeved on the outer side of the third limiting ring 62 . The lower surface of the lower limiting ring 72 is matched with the upper arc surface of the arc rod 61 .

[0071] The upper ends of the quadrangular prisms 71 are fixedly connected together by an upper limit ring 73. The abutting end 32 of the valve core 3 is provided with an annular groove 74. The annular groove 74 is coaxially arranged with the homogenizing hole 22. The groove wall of the annular groove 74 is provided with an inclined surface. The upper limit ring 73 is located in the annular groove 74. The upper limit ring 73 is rotatably connected to the valve core 3 around its own axis through the annular groove 74, and the inner diameter of the upper limit ring 73 gradually increases from bottom to top.

[0072] Through the cooperation between the valve core 3 and the upper limit ring 73 , the valve core 3 applies a downward force to the quadrangular column 71 , while the elastic support member applies an upward elastic force to the quadrangular column 71 , so as to jointly limit the quadrangular column 71 stably in the homogenizing hole 22 at all times.

[0073] The implementation principle of Example 2 is as follows: when the high-pressure material in the transfer chamber 13 overflows from the abutting valve surface 21 of the valve seat 2 into the homogenizing hole 22 at a high speed and converges and rushes into the center of the homogenizing hole 22, multiple strands of annularly arranged high-pressure materials are first guided by the quadrangular prism 71 to pass through the guide gap 75 and enter the center of the homogenizing hole 22. At this time, the trajectory of the high-pressure material is clearer, the collision accuracy is higher, and the homogenization effect is better.

[0074] Furthermore, when one stream of high-pressure material hits one of the tetrahedrons 71, the entire tetrahedron 71 moves, causing the other tetrahedron 71 to collide with another stream of high-pressure material. It can be seen that the entire tetrahedron 71, as an intermediary structure, can transmit the impact force of multiple high-pressure materials, that is, it is essentially still a collision between multiple streams of high-pressure materials, but through the entire tetrahedron 71, the collision relationship between two streams of high-pressure materials that would not originally collide is reduced, thereby improving the collision uniformity and homogenization effect.

[0075] Finally, when the elastic support member and the guide member need to be maintained or replaced, the external push rod 10 can be removed first, and then the separated ends of the arc rod 61 are forced to approach each other. At this time, the guide member moves upward and pushes open the valve core 3 until the distance between the separated ends of the arc rod 61 is smaller than the aperture of the material discharge hole 14. Then, the elastic support member and the guide member can be taken out from the position of the material discharge hole 14, which is convenient and quick.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
