Description

Technical Field

[0001] The present invention relates to a homogenizing valve described in the first part of claim 1 and a homogenizing valve described in the first part of claim 19.

Background Art

[0002] Such a homogenizing valve is used to evenly divide different components such as fruit juice or dairy products and distribute them homogeneously in a medium. For this purpose, the medium to be homogenized is passed under high pressure (usually exceeding 150 bar) on a shearing edge, and then, behind it, the medium to be homogenized expands. In particular, fruit fibers in fruit juice or fat droplets in an emulsion such as milk are effectively broken up.

[0003] In particular, when using high pressure for homogenization, a large adjustment force is required to set a homogenization gap in the homogenizing valve. The large adjustment force required is due to the operating pressure acting on the pressure surface of the valve body in the adjustment direction of the valve body.

Summary of the Invention

Problems to be Solved by the Invention

[0004] An object of the present invention is to provide a homogenizing valve that can control or move the valve body with a significantly low adjustment force.

Means for Solving the Problems

[0005] This object is solved by a homogenizing valve having the features of claim 1. The homogenizing valve according to the present invention for a medium to be homogenized under system pressure has a valve housing, and the valve housing has an inlet channel and an outlet channel for the medium.

[0006] The homogenizing valve also has a valve seat disposed in the valve housing having a receiving portion, and the valve body extends movably in its longitudinal direction through the receiving portion.

[0007] The pressure chamber connected to the inlet channel is formed on the outer jacket surface of the valve seat and / or the valve body. Furthermore, an adjustment unit is operably connected to the valve body. The axial position of the valve body within the receiving part can be adjusted using the adjustment unit. The axial movement should be understood as the axial movement with respect to the virtual central axis of the receiving part.

[0008] By moving the valve body within the valve seat, the flow resistance from the inlet channel to the outlet channel can be adjusted. Between the inner wall of the valve seat forming the receiving part and the valve body, there are a shear gap formed by a blade edge and a conical wall region facing the blade edge, and an expansion chamber provided on the downstream side in the flow direction of the shear gap and communicating with the outlet channel. When viewed from the displacement direction of the valve body, they are formed on both sides of the pressure chamber.

[0009] Such an arrangement of the shear gaps on both sides of the pressure chamber means that, as a result, substantially no force acts on the movable valve body in the direction of the longitudinal axis of the valve body corresponding to the movement direction of the valve body.

[0010] Therefore, by moving the valve body using the adjustment unit, the shear gap can be adjusted with very little effort. Modifications of advantageous embodiments of the present invention are the subject matter of the dependent claims.

[0011] According to an advantageous embodiment, the length of the first blade edge close to the adjustment unit is longer in the circumferential direction than the length of the second blade edge arranged away from the adjustment unit. Thereby, the valve body can be extremely easily attached axially to the valve seat.

[0012] According to a preferred further development, when viewed from the direction of the longitudinal axis of the valve body, the blade edge is double conical. According to a modification of the first preferred embodiment, in the displacement direction of the valve body, between the conical regions of the receiving part, the blade edge is arranged on the outer jacket surface of the valve body.

[0013] In particular, when forming the valve body, the blade edge can be formed on the outer jacket surface of the valve body in a very precise manner. According to a modification of a further embodiment, the blade edge is configured as a separate component attached to the outer jacket surface of the valve body. This configuration enables the components of the valve body to be manufactured from different materials. In particular, the blade edge can be formed from a particularly hard material in order to further extend its service life.

[0014] According to a modification of an alternative embodiment, the reverse arrangement is also conceivable. In this case, the blade edge is arranged on the inner surface of the valve seat between the regions of the outer jacket surface of the valve body that are conical in the displacement direction of the valve body. The modifications of both embodiments make it possible to easily adjust the shear gap by moving the valve body within the valve seat.

[0015] According to a modification of a further preferred embodiment, guide surfaces are provided on the inner surface of the valve seat and the jacket surface of the valve body, and grooves connected to the respective expansion chambers are provided on the guide surfaces of the valve seat and / or the valve body. The grooves cause additional backflow of the expanded medium by guiding the medium when it enters the grooves from the expansion chambers.

[0016] According to a preferred further development, the grooves extend linearly parallel to the movement direction of the valve body. A curved configuration of the grooves is also conceivable. In a modification of the preferred embodiment, the grooves are formed on the guide surface of the valve body.

[0017] In a modification of the alternative embodiment, the grooves are formed on the guide surface of the valve seat. According to a variant of a further preferred embodiment, the guide surfaces of the valve body and the valve seat are conical in the direction of the longitudinal axis of the valve body.

[0018] In a variant of an alternative embodiment, the guide surfaces of the valve body and the valve seat are formed cylindrically in the direction of the longitudinal axis of the valve body. In a variant of this embodiment, more accurate guidance of the valve body within the valve seat is enabled.

[0019] According to a variant of a further preferred embodiment, a channel connected to the outlet is provided within the valve housing downstream of the valve body. According to a preferred further development, these channels open into the mixing region of the outlet or into a mixing chamber upstream of the outlet, nozzles are arranged upstream within each channel, and the injection directions of the nozzles are aligned with each other.

[0020] These nozzles enable a reciprocating flow of the already expanded medium and further enhance the quality of homogenization. In a variant of a further preferred embodiment, the diameter of the conical valve seat and the diameter of the part of the valve body having the conical outer jacket surface are configured to increase towards the adjustment unit.

[0021] The valve seat is preferably installed within the receiving part of the valve housing so as to prevent movement. As a variant of an alternative embodiment, it is also conceivable to form the valve seat as a component of the valve housing. In a variant of another preferred embodiment, an elastic unit is arranged between the adjustment unit and the valve body.

[0022] Preferably, the elastic unit configured as a spring assembly having at least two disc springs causes the valve body to move briefly in the direction of the adjustment unit due to different surfaces of the blade edges on both sides of the pressure chamber when the operating pressure rises, thereby releasing the pressure. This makes it easy to prevent clogging of the pressure chamber. The height of the gap temporarily increases until the initial operating pressure in the pressure chamber is reached again. As a result, the valve body is automatically pushed back to its initial position by the force of the elastic unit.

[0023] Another variant of a further embodiment of the homogenizing valve according to the invention comprises a valve housing with an outlet channel for the medium, and a receiving part arranged in the valve housing along a displacement axis and at least partially conical, in which a valve body fixed to the valve housing is attached with at least a partially conical outer jacket surface, and a valve seat and an inlet channel.

[0024] The pressure chamber is connected to an inlet channel formed in the receiving part of the valve seat and / or the outer jacket surface of the valve body. The adjustment unit is operatively connected to the valve seat. The flow of the medium from the inlet channel to the outlet channel can be adjusted by the interaction between the valve body and the valve seat.

[0025] Here too, on both sides of the pressure chamber in the displacement direction of the valve body, a shear gap is formed between the inner wall of the valve seat forming the receiving part and the valve body by a blade edge and a wall region conical with respect to the blade edge, and an expansion chamber connected to the outlet channel is formed downstream in the flow direction of the shear gap.

[0026] Also in this variant of the embodiment, the medium to be homogenized is centrally supplied from the valve body to the pressure chamber, and from there the medium continues to flow beyond the blade edge in the displacement direction of the valve body. In this case, by displacing the valve seat, it is possible to adjust the shear gap with little effort.

Mode for Carrying Out the Invention

[0028] In the following description of the figures, terms such as up, down, left, right, front, and back specifically refer to the exemplary representations and positions of the homogenizing valve, valve housing, valve seat, valve body, blade edge, expansion chamber, etc. selected in each figure. These terms should not be understood in a limiting sense, that is, these criteria may vary depending on different operating positions or mirror-symmetric configurations, etc.

[0029] In Figure 1, reference numeral 1 is used to show a variant of an embodiment of a homogenizing valve according to the present invention as a whole. The homogenizing valve 1 has a valve housing 2, and the valve housing has an inlet channel 21 and an outlet channel 22 for the medium to be homogenized.

[0030] A valve seat 4 is arranged in the valve housing 2. The valve seat 4 has a receiving portion 42, and through this receiving portion, the valve body 3 of the homogenizing valve 1 extends movably in the direction of its longitudinal axis L.

[0031] As shown in Figure 1, the valve seat 4 is installed in the valve housing 2 and is configured as a separate component sealed from the valve housing 2 by a static high-pressure seal 13. It is also conceivable to integrally form the valve seat 4 with the valve housing 2.

[0032] The receiving portion 42 of the valve seat 4 is configured as a through-hole, and through this through-hole, the valve region 33 of the valve body 3 extends. The axial position of the valve body 3 within the receiving portion 42 can be adjusted with the aid of an adjustment unit 5 in the form of a manually rotatable screw, for example, as shown in Figure 1.

[0033] In the illustrated exemplary embodiment, the adjustment unit 5 is screwed into a guide housing 6, and its body 61 is firmly screwed into the valve housing 2 using a fixing screw 62.

[0034] In a modified example of the embodiment shown here, the guide housing 6 has a receiving portion 63 that extends into a receiving portion within the valve housing 2. The inner surface of this receiving portion 63 functions as a guide surface for the head 31 of the valve body 3, and the guide jacket 312 of the valve body 3 forms a sliding surface on the inner surface of the receiving portion 63 of the guide housing 6 that is displaceable in the direction of the longitudinal axis L of the valve body 3. The longitudinal axis L is also the (virtual) central axis of the receiving portion 42.

[0035] In order to seal the head 31 of the valve body 3 against the inner wall of the receiving portion 63 of the guide housing 6, a seal receiving groove 313 is provided in the guide jacket 312 of the head 31 of the valve body 3, and a dynamic low-pressure seal 12 is accommodated therein. The end face 311 of the head 31 of the valve body 3 serves as a contact surface against the end face of the adjustment unit 5.

[0036] As further shown in FIGS. 1 and 2, a pressure chamber 7 connected to the inlet channel 21 is formed in the receiving portion 42 of the valve seat 4 and / or on the outer jacket surface 33 of the valve body 3. In a modified example of the embodiment shown in FIGS. 1 and 2, the receiving portion 42 of the valve seat 4 is widened annularly around the inlet channel 41 of the pressure chamber to form the pressure chamber 7.

[0037] Between the inner wall of the valve seat 4 forming the receiving portion 42 and the valve body 3, in each case, as further shown in FIGS. 1 and 2, shear gaps are formed on both sides of the pressure chamber 7 by the blade edges 8a, 8b and the conical wall regions for the blade edges, and downstream of the shear gap in the flow direction, an expansion chamber 9 connected to the outlet channel 22 is formed.

[0038] Since the medium to be homogenized is supplied to the pressure chamber 7 via the inlet channel 21, especially under a high pressure exceeding 150 bar, the blade edges 8a, 8b provided on both sides of the pressure chamber 7 ensure that substantially no force is exerted on the valve body 3 movable by the medium under the high pressure in the moving direction of the valve body 3, that is, in the direction of the longitudinal axis L.

[0039] The shearing gap is adjusted by moving the valve body 3 relative to the valve seat 4. The gap dimensions of the shearing gap between the blade edges 8a, 8b and the conical wall region are the same for both sides. Depending on the medium to be homogenized, the preferred setting of the gap dimension is preferably in the range of 0.01 mm to 0.1 mm.

[0040] In all variants of the illustrated embodiment, the length of the blade edge 8a close to the adjustment unit 5 is longer circumferentially than the length of the blade edge 8b remote from the adjustment unit 5. Accordingly, the inner diameter of the receiving part 42 in the region close to the adjustment unit 5 is larger than the inner diameter of the receiving part 42 remote from the adjustment unit 5.

[0041] The blade edges 8a, 8b preferably have a double conical configuration, with a front flank narrowing the shearing gap from the pressure chamber 7, a short portion adjacent thereto having a constant radial width in the direction of the longitudinal axis L of the valve body 3, and a rear flank adjacent to this portion widening the shearing gap towards the expansion chamber 9.

[0042] In a variant of the embodiment of the homogenizing valve 1 shown in FIGS. 1 to 5, the blade edges 8a, 8b are positioned on the outer jacket surface of the valve body 3 between the regions of the receiving part 42 formed conically in the displacement direction of the valve body 3, whereas in the variant of the embodiment shown in FIGS. 6 and 7, the valve region 33' of the valve body 3 is linearly conical.

[0043] The blade edges 8a, 8b are here arranged on the inner surface of the valve seat 4, and the inner surface of the valve seat 4 forms a receiving part 42 in the displacement direction of the valve body 3 between the conical regions of the outer jacket surface of the valve body 3. In the variant of the embodiment shown in FIGS. 6 and 7, the annular expansion chamber 9 is also formed on the inner wall of the valve seat 4' forming the receiving part 42'.

[0044] In any modification of the embodiments, the blade edges 8a and 8b can be integrally formed on the respective components, i.e., on the valve body 3 or the valve seat 4 in the embodiments shown in FIGS. 1 to 5, or can be formed as separate components attached to the valve body 3 or the valve seat 4.

[0045] As is also apparent from FIGS. 2 and 4, the guide surfaces 34, 35, 43, 44 are provided on the inner surface of the valve seat 4 and the jacket surface of the valve body 3, and the grooves 10 connected to the respective expansion chambers 9 are provided on the guide surfaces 43, 44 of the valve seat 4 or the guide surfaces 34, 35 of the valve body 3.

[0046] In a modification of the embodiment of the homogenizing valve 1 shown in FIGS. 1 to 5, these grooves 10 are provided on the guide surfaces 34, 35 of the valve body 3. The grooves 10 preferably extend linearly parallel to the moving direction of the valve body 3.

[0047] In a modification of an alternative embodiment of the homogenizing valve 1, as is apparent from FIG. 6, the grooves 10 are formed on the guide surfaces 43, 44 of the valve seat 4. Also, as can be seen from FIGS. 1 to 8, the guide surfaces 34, 35, 43, 44 of the valve body 3 and the valve seat 4 are formed in a conical shape in the direction of the longitudinal axis L of the valve body 3.

[0048] In a modification of a further embodiment shown as an example in FIG. 9, the guide surfaces 34', 35", 43"' and 44"' are cylindrical, where the diameter of the valve body 3 and, correspondingly, the receiving portion 42 of the valve seat 4 in the region of the guide surfaces 34, 43"' is larger than the diameter in the region of the guide surfaces 35"', 44"'.

[0049] By configuring these guide surfaces 34"', 35"', 43"', 44"' as cylindrical surfaces, in this case, the guide surfaces are in sliding contact with the receiving portion 42 at each position of the valve body 3, so that better guiding of the valve body 3 in the valve seat 4 is possible. As further illustrated in a modification of the embodiment shown in FIG. 3, channels 23, 24, which are preferably connected to the outlet 22, are provided in the valve housing 2 downstream of the valve body 3.

[0050] These channels 23, 24 open into the mixing region of the outlet 22 or into the mixing chamber 25 upstream of the outlet, so that the homogenized medium is recombined after expansion in the two expansion chambers 9 in the mixing region of the outlet 22 or in the mixing chamber 25 upstream of the outlet with cross-inflow.

[0051] Preferably, nozzles 11 are arranged in each of the channels 23, 24, and the injection directions of the nozzles 11 are aligned such that the flows of the two media directed through the respective nozzles 11 merge at the mixing region of the outlet 22 or in the mixing chamber 25 upstream thereof at an accelerated speed. Cross-inflow of partial flows of the medium also occurs in the two expansion chambers 9 in the transition region to the groove 10, and the medium is discharged from the region of the valve body 3 into the channels 23, 24 via this expansion chamber 9.

[0052] Also, as shown by way of example in FIG. 8, by interchanging the positions of the blade edges 8a, 8b and the guide surfaces 34, 35, 43, 44, it is also conceivable that the medium is guided through the groove 10 after entering the pressure chamber and then guided to each expansion chamber 9 via the blade edges 8a, 8b.

[0053] In a modification of a further embodiment shown in FIG. 10, an elastic unit 15 is arranged between the adjustment unit 5 and the valve body 3. Here, the elastic unit 15, configured as a spring assembly with several, especially at least two disc springs, during operation, for example, if the operating pressure becomes too high due to the closure of the pressure chamber 7, the valve body 3 moves against the force of the elastic unit 15 to release the pressure, and thus, by increasing the height of the gap until the operating pressure reaches the initial value again, ensures that the valve body 3 is pushed back to the initial position by the elastic unit 15.

[0054] The movement of the valve body 3 against the force of the elastic unit 15 is based on the difference between the region of the blade edge 8a on the pressure chamber 7 side close to the adjustment unit 5 and the region of the blade edge 8b on the pressure chamber 7 side away from the adjustment unit 5, and the region of the blade edge 8a on the pressure chamber 7 side close to the adjustment unit 5 is larger than the region of the blade edge 8b on the pressure chamber 7 side away from the adjustment unit 5.

[0055] In this case, by adjusting the adjustment unit 5, the holding force of the elastic unit 15 can be mainly adjusted. A modification of another embodiment of such a homogenizing valve 100 is shown in FIG. 11.

[0056] In a modification of this embodiment, outlet channels 122, 123 for the medium are formed in the valve housing 120. The valve housing 120 is provided with a valve seat 140 and an inlet 131 arranged along the displacement axis L, and at least a partially conical receiving portion 142 is also provided on this valve seat. In this case, a valve body 130 fixed to the valve housing 120 is attached to the receiving portion 142 using at least a partially conical outer jacket surface 133.

[0057] The inlet 131 is here configured as a channel formed from one end face into the valve body along the longitudinal axis, and from its end, several channels branch radially or substantially radially into a pressure chamber 170 integrally formed within the receiving portion 142 of the valve seat 140 and / or the outer jacket surface 133 of the valve body 130. Also, the pressure chamber 170 is provided with annular grooves as in the modification of the embodiment shown in FIGS. 1 to 9. Here, it is preferable that the material recess for forming the pressure chamber 170 is provided in the valve body 130.

[0058] Furthermore, in a modified example of this embodiment, the adjustment unit 150 is operably connected to the valve seat 140. The flow of the medium from the inlet 131 to the outlet channel 122 in the valve housing 120 can be adjusted by moving the valve seat 140 relative to the valve body 130 that is permanently attached to the valve housing 120.

[0059] Here too, between the inner wall of the valve seat 140 that forms the receiving portions 142 on both sides of the pressure chamber 170 in the displacement direction of the valve body 130 and the valve body 130, blade edges 8a, 8b and a conical wall region thereagainst are formed, and on the downstream side of the shear gap in the flow direction, an expansion chamber 9 connected to the outlet channel 122 is formed.

[0060] Furthermore, in the modified example of this embodiment, a groove 10 is also provided downstream of the expansion chamber 9, and this groove can be formed either on the outer jacket surface 133 of the valve body 130 or on the inner surface of the valve seat 140 that forms the receiving portion 142.

[0061] In the illustrated exemplary embodiment, the blade edges 8a, 8b are formed by the edges of the outer jacket surface 133 of the valve body 130 at the transition portion to the expansion chamber 9.
