Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

Referring to fig. 1 to 3, the present embodiment provides an axial flow type regulating valve, which specifically includes a valve main body 1 and a ball core 2.

The valve body 1 is provided with a first fluid channel 11 arranged along the axial direction of the valve body 1, the first fluid channel 11 is of a cylindrical structure, the ball core 2 is positioned in the first fluid channel 11, an annular concave cavity 3 which is arranged along the circumferential direction of the first fluid channel 11 and is used for containing the ball core 2 is arranged on the cavity wall of the first fluid channel 11, and the ball core 2 and the valve body 1 are coaxially arranged. The axial direction of the valve body 1 can specifically refer to the direction of the X-X axis shown in fig. 1.

In specific implementation, the core 2 has a second fluid channel 21, an inlet of the second fluid channel 21 can be communicated with an inlet of the first fluid channel 11, and an outlet of the second fluid channel 21 can be communicated with an outlet of the first fluid channel 11, so that the fluid in the first fluid channel 11 can sequentially flow out through the second fluid channel 21 and the outlet of the first fluid channel 11.

Referring to fig. 1, a flow adjusting plate 4 is fixedly disposed in the second fluid channel 21, the flow adjusting plate 4 is vertically disposed in the second fluid channel 21, and a plurality of through holes 41 are disposed at intervals on the flow adjusting plate 4 for fluid to flow through. The core 2 is rotatable in the annular recess 3 about a central axis to adjust the opening size of the inlet of the second fluid passage 21 so that the flow rate of the axial flow type adjusting valve can be adjusted. Wherein, the central axis is perpendicular to the central axis of the valve body 1. Specifically, the central axis is specifically the Y-Y axis shown in fig. 1, and the central axis of the valve body 1 is the X-X axis shown in fig. 1.

It should be noted that the flow adjustment plate 4 is vertically disposed along the Y-Y axis shown in fig. 1, and the through hole 41 is disposed through the flow adjustment plate 4 in the Z-Z axis direction shown in fig. 3. Meanwhile, referring to fig. 1, the size of the flow regulating plate 4 matches the size of the second fluid passage 21 in the X-X axis direction. In this embodiment, the X-X axis, the Y-Y axis and the Z-Z axis are all the corresponding directions of the axial flow valve shown in fig. 1 to 3 when the axial flow valve is in the fully open state.

In practice, the valve is opened and closed and the flow rate is adjusted by rotating the ball core 2 around the Y-Y axis in the annular concave cavity 3 to adjust the opening size of the inlet of the second fluid channel 21, i.e. the opening size of the inlet of the second fluid channel 21 exposed in the first fluid channel 11. The axial flow type valve is simple in structure, convenient to process, low in manufacturing cost and flexible in fluid flow adjusting process.

Wherein, the mode that current piston reciprocating motion carried out flow control in the sleeve, the stroke when needing piston reciprocating motion is reserved, leads to current governing valve to use inconveniently, and required space is great during the use, and the structure is complicated. Meanwhile, since the flow holes in the sleeve are generally small in size, the flow holes are easily blocked by impurities contained in the fluid during the flow rate adjustment process, which affects the flow rate adjustment process, the adjustment accuracy and the flow capacity of the fluid.

Compared with the existing piston sleeve type regulating valve, the axial flow type regulating valve only needs to enable the ball core 2 to rotate around the central shaft, so that the use space of the axial flow type regulating valve can be saved to a certain extent, the structure of the axial flow type regulating valve is simple, and the flexibility of flow regulation of the axial flow type regulating valve is further improved.

That is to say, with the governing valve under the specification and dimension, the axial-flow type governing valve that provides in this embodiment compares current piston sleeve formula governing valve, and the fluid regulation process is more convenient, nimble, and fluid circulation ability reinforce.

For example, since the core 2 can rotate in the annular cavity 3, the second fluid channel 21 is provided on the core 2, so that when the core 2 rotates to the extent that the second fluid channel 21 extends perpendicular to the axial direction of the valve body 1, the side of the core 2 where the second fluid channel 21 is not provided will be blocked in the first fluid channel 11. That is, the second body passage 21 does not communicate with the first fluid passage 11, and the axial flow regulating valve is in a fully closed state.

Referring to fig. 1, when the ball core 2 is rotated until the extending direction of the second fluid passage 21 is parallel to the axial direction of the valve main body 1, the second fluid passage 21 is completely communicated with the first fluid passage 11, and the axial flow type regulating valve is in a fully open state. Since the flow regulating plate 4 is provided in the second fluid passage 21, when the flow regulating valve is fully opened, the fluid flows along both sides of the axial direction of the second fluid passage 21 in the Z-Z axis direction shown in fig. 3, and when impurities are contained in the fluid, the impurities flow out together with the fluid.

When the ball core 2 is rotated to a position where the extending direction of the second fluid channel 21 forms an included angle with the axial direction of the valve body 1 but is not perpendicular to each other, at least a portion of the ball core 2 not provided with the second fluid channel 21 is blocked in the first fluid channel 11. That is, a part of the inlet of the second fluid passage 21 communicates with the first fluid passage 11, and the axial-flow type adjustment valve is in a semi-open state. During specific implementation, the size of the communication between the second fluid channel 21 and the inner cavity part can be adjusted according to the difference of the included angle between the axial direction of the second fluid channel 21 and the axial direction of the inner cavity, so that the primary adjustment of the flow of the axial flow type adjusting valve is realized.

Further, by providing the flow rate adjustment plate 4 in the second fluid passage 21, the flow rate adjustment plate 4 and the axial direction of the first fluid passage 11 also have the same angle when the axial flow adjustment valve is in the half-open state. When fluid passes through the second fluid passage 21, the fluid in the second fluid passage 21 flows through the through-hole 41 of the flow rate adjustment plate 4.

The through hole 41 of the flow adjustment plate 4 disturbs the fluid flowing through the flow adjustment plate 4 to a certain extent to change the original flow path of the fluid in the second fluid passage 21 and the flow speed and pressure of the fluid. Meanwhile, when the fluid flows through the flow adjusting plate 4, the fluid can also wash the flow adjusting plate 4 to a certain degree, so that the surface of the flow adjusting plate 4 is cleaned to a certain degree.

That is, the through hole 41 of the flow adjustment plate 4 can further adjust the flow of the fluid according to the difference in the opening size of the inlet of the second fluid passage 21 when the axial flow adjustment valve is in the half-open state, thereby improving the accuracy and precision of the flow adjustment.

During specific implementation, the number of the through holes 41 can be adjusted according to actual flow requirements and the equal percentage characteristic curve of the axial flow type regulating valve, so that the regulating precision of the axial flow type regulating valve is improved.

Illustratively, when the fluid at the inlet of the first fluid channel 11 passes through the flow regulating plate 4, the fluid is forced to pass through the through hole 41, so that the pressure reduction and the flow restriction of the fluid can be realized. That is, the velocity of the fluid is increased and the fluid pressure is decreased; and after the fluid completely passes through the through-hole 41, the fluid velocity decreases and the pressure increases. By measuring the pressure difference of the fluid at the inlet and the outlet of the second fluid channel 21, the flow rate of the fluid can be correspondingly obtained, and finally the flow at the outlet of the first fluid channel 11 in unit time is obtained, that is, the flow regulation precision of the fluid is high.

When the axial flow type regulating valve is in different semi-open states, that is, when the included angle between the flow regulating plate 4 and the axial direction of the first fluid channel 11 is different, the projected size of the through hole 41 on the Z-Z axis shown in fig. 1 of the first fluid channel 11 is different, resulting in different sizes of the part of the through hole 41 through which the fluid can flow, and thus different disturbance effects of the through hole 41 on the fluid are obtained. Therefore, the staff can adjust the rotation angle of the ball core 2 according to the actual flow demand to further adjust the flow and meet the flow demand of downstream users.

Meanwhile, when the axial flow type regulating valve is in a half-open state, a part of fluid flows on the surface of the flow regulating plate 4 on the Z-Z axis shown in fig. 3, the inclined flow regulating plate 4 guides the part of fluid to a certain degree, so that impurities contained in the part of fluid can smoothly flow out from the surface of the flow regulating plate 4, a self-cleaning function is achieved to a certain degree, the possibility of blockage of the second fluid channel 21 by the impurities in the fluid is reduced to a certain degree, the flow regulating precision of the axial flow type regulating valve is ensured, the possibility of blockage of the axial flow type regulating valve is reduced, and the generation of faults caused by the blockage is reduced.

Referring to fig. 1, a transmission rod 5 is relatively fixed on the ball core 2, and a driving member is disposed at an end of the transmission rod 5 away from the ball core 2, and is used for driving the transmission rod 5 to rotate around the Y-Y axis so as to drive the ball core 2 to rotate around the Y-Y axis. The specific rotation directions of the core 2 and the transmission rod 5 can refer to the directions of the arc rotation arrows shown in fig. 1.

The valve body 1 includes a hollow first body section 12 and a hollow second body section 13 connected to one end of the first body section 12, a first inner cavity of the first body section 12 and a second inner cavity of the second body section 13 are both cylindrical, both ends of the first body section 12 in the axial direction are openings communicated with the first inner cavity, and both ends of the second body section 13 in the axial direction are openings communicated with the second inner cavity.

In specific implementation, the mutually close sides of the first main body segment 12 and the second main body segment 13 are both provided with a cavity recessed towards the direction away from the cavity, and the cavity is formed into the annular concave cavity 3. In addition, the axial-flow type regulating valve also comprises two hollow regulating seats 6 which are oppositely arranged, wherein one regulating seat 6 is positioned in the annular concave cavity 3 on the first main body section 12, the other regulating seat 6 is positioned in the annular concave cavity 3 on the second main body section 13, the ball core 2 is positioned between the two regulating seats 6 and is attached to each regulating seat 6, and in the Y-Y direction, the inner diameter of one end, far away from the ball core 2, of each regulating seat 6 is matched with the size of the first fluid channel 11.

Wherein, adjust seat 6 be used for with the laminating of 2 outer walls of ball core to at the in-process that this axial-flow type governing valve used, keep the leakproofness of adjusting seat 6 and ball core 2 throughout, avoid leading to the joint face department of adjusting seat 6 and ball core 2 to the regulation seat 6 of flowing through of leading to, simple structure, and sealing performance is good.

The valve body 1 comprises the first body section 12 and the second body section 13, so that the installation and the disassembly of the adjusting seat 6 and the ball core 2 are facilitated, the structure is simple, and the use is convenient.

The axial-flow type regulating valve provided by the embodiment is provided with a valve main body 1 and a ball core 2, the valve main body 1 is provided with a first fluid channel 11 arranged along the axial direction of the valve main body 1, the first fluid channel 11 is of a cylindrical structure, the ball core 2 is positioned in the first fluid channel 11, an annular concave cavity 3 which is arranged along the circumferential direction of the first fluid channel 11 and is used for accommodating the ball core 2 is arranged on the cavity wall of the first fluid channel 11, and the ball core 2 and the valve main body 1 are coaxially arranged. The core 2 has a second fluid channel 21, an inlet of the second fluid channel 21 can communicate with an inlet of the first fluid channel 11, and an outlet of the second fluid channel 21 can communicate with an outlet of the first fluid channel 11, so that the fluid in the first fluid channel 11 can flow out through the second fluid channel 21 and the outlet of the first fluid channel 11 in sequence. Meanwhile, the flow adjusting plate 4 is fixedly arranged in the second fluid channel 21, the flow adjusting plate 4 is vertically arranged in the second fluid channel 21, and a plurality of through holes 41 which are arranged at intervals and are used for fluid to flow through are formed in the flow adjusting plate 4. The flow rate of the axial flow type regulating valve is regulated by adjusting the opening size of the inlet of the second fluid passage 21 by allowing the core 2 to rotate in the annular concave cavity 3 about a central axis. That is to say, when the flow rate of the valve is adjusted, the opening size of the inlet of the second fluid channel 21, that is, the size of the opening of the inlet of the second fluid channel 21 exposed in the first fluid channel 11, can be adjusted by only rotating the ball core 2 around the central axis in the annular concave cavity 3, so that the flexible adjustment of the flow rate of the fluid in the axial flow valve can be realized, and the adjustment process is simple. Simultaneously, compare current piston and carry out flow control's mode in the sleeve reciprocating motion, this axial-flow type governing valve only need make ball core 2 around the center pin rotation can to can save axial-flow type governing valve's usage space to a certain extent, and this axial-flow type governing valve's simple structure, further improved axial-flow type governing valve flow control's flexibility. Meanwhile, when the ball core 2 rotates to a position where the extending direction of the second fluid channel 21 is not perpendicular to the axial direction of the valve body 1, the fluid in the second fluid channel 21 can flow through the through hole 41 of the flow adjusting plate 4, and the through hole 41 of the flow adjusting plate 4 can disturb the fluid flowing through the flow adjusting plate 4 to a certain extent, so that the original flow path of the fluid in the second fluid channel 21 and the flow speed and pressure of the fluid are changed, the size of the opening of the inlet of the second fluid channel 21 can be adjusted while the use of the flow adjusting plate 4 is matched, the accuracy and the precision of flow adjustment are further improved, and the axial flow type adjusting valve can meet the percentage characteristics of flow.

Specifically, in the direction of the central axis, the outer edge of the flow rate regulation plate 4 abuts against the inner wall of the second fluid passage 21. Wherein the central axis is specifically the Y-Y axis shown in fig. 1.

That is to say, in the Y-Y axis direction, the size of the flow adjustment plate 4 is consistent with the size of the portion of the second fluid passage 21 corresponding to the flow adjustment plate 4, so that the contact area between the flow adjustment plate 4 and the fluid in the second fluid passage 21 is increased to a certain extent, and thus the fluid in the second fluid passage 21 can be disturbed as much as possible, and the accuracy of the flow control of the axial flow type adjustment valve is improved.

In a specific implementation, the flow adjusting plate 4 is a rectangular plate, and in the direction of the central axis, the shapes of two opposite sides of the rectangular plate are matched with the shape of the inner wall of the second fluid channel 21.

That is, referring to fig. 2, two sides of the rectangular plate in the Y-Y direction are completely attached to the inner wall of the second fluid channel 21, so that the stability of the flow adjustment plate 4 connected to the inner wall of the second fluid channel 21 is improved, that is, the flow adjustment plate 4 is stably connected to the inner wall of the second fluid channel 21, so that when a fluid passes through the flow adjustment plate 4, the flow adjustment plate 4 is not inclined under the impact of the fluid, and the disturbance effect of the flow adjustment plate 4 on the fluid is ensured. Of course, the flow adjusting plate 4 may have any suitable shape such as a circular shape or an elliptical shape.

In some embodiments, the flow adjustment plate 4 is provided in plurality, and the plurality of flow adjustment plates 4 are arranged at intervals in a predetermined direction. The preset direction is perpendicular to the central axis of the valve body 1 and perpendicular to the central axis. Specifically, for convenience of explanation of the arrangement direction of the plurality of flow adjustment plates 4, the Z-Z direction shown in fig. 3 when the axial flow adjustment valve shown in fig. 1 to 3 is in the fully open state will be taken as an example.

For example, it is assumed that in fig. 1, the fluid flows from left to right, i.e., the fluid flows from left to right in the first fluid channel 11 and the second fluid channel 21. When the axial flow type adjusting valve is in a half-open state, the plurality of flow adjusting plates 4 are referred to as a first flow adjusting plate, a second flow adjusting plate, a third flow adjusting plate and the like in sequence from left to right.

When the axial flow regulating valve is in the half-open state, the fluid passes through the plurality of through holes 41 of the first flow regulating plate 4, the plurality of through holes 41 of the second flow regulating plate 4, and the like in this order. That is, the fluid in the second fluid passage 21 can be disturbed in multiple layers to adjust the fluid at the inlet of the second fluid passage 21 in multiple stages of speed and pressure, and the control accuracy of the fluid flow rate in the second fluid passage 21 is further improved.

In specific implementation, all the flow adjusting plates 4 are arranged in parallel, and the distance between two adjacent flow adjusting plates 4 is equal.

That is, the plurality of flow adjusting plates 4 are parallel and uniformly distributed along the Z-Z direction shown in fig. 3, that is, the center of the whole ball core 2 is ensured to coincide with the center of gravity, so that the stability of the ball core 2 in the rotation process can be improved; in the flow adjusting process, the disturbance effect of the two adjacent flow adjusting plates 4 on the fluid is approximately the same, so that the adjusting precision of the flow adjusting plates 4 on the flow can be ensured, and the flow can be accurately adjusted and controlled conveniently.

In some embodiments, the plurality of through holes 41 are uniformly arranged on the flow regulating plate 4. By the arrangement, on one hand, the center of the flow adjusting plate 4 is superposed with the gravity center, so that the stability of the flow adjusting plate 4 is good; on the other hand, the through holes 41 on the flow regulating plate 4 can uniformly disturb the flowing fluid, so that the flow regulating precision can be regulated and controlled.

Further, the hole diameter of each through hole 41 is made larger than the maximum outer contour size of the impurities contained in the fluid. Illustratively, the aperture of each through hole 41 is 8mm to 2mm, and the maximum outer contour dimension of impurities contained in the fluid is 0.1mm to 2mm.

By the arrangement, when the fluid passes through the through hole 41, all impurities contained in the fluid can be driven to pass through together, so that part of impurities in the fluid are prevented from being blocked in the through hole 41 to a certain extent, and the adjusting capacity and accuracy of the through hole 41 on the fluid flow are ensured.

In practice, the second fluid passage 21 is made cylindrical, and the cross-sectional dimension of the second fluid passage 21 in the direction of the central axis matches the inner diameter of the portion of the first fluid passage 11 where the annular recessed cavity 3 is not provided.

By the arrangement, the consistency and the continuity of the parts, provided for fluid to flow, of the second fluid channel 21 and the first fluid channel 11 are improved, so that the fluid of the first fluid channel 11 can enter the second fluid channel 21 and cannot be blocked at the joint position of the outer wall of the ball core 2 and the first fluid channel 11, and the smoothness of fluid flow is ensured.
