Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve technology, specifically to a valve body with adjustable flow rate. Background Technology
[0002] An adjustable flow valve body is a device used to control fluid flow. The valve body typically consists of a valve seat, valve core, valve stem, actuator, and seals. The valve seat is an annular structure in the pipeline that provides a sealing and support surface for the valve core, ensuring a tight seal when the valve is closed. The valve core is the key component for flow control, and its shape and structure vary widely, commonly including plunger, ball, and butterfly valve types. Fluid flow is adjusted by changing the flow area between the valve core and the valve seat. The valve stem connects the valve core and the actuator, transmitting driving force and enabling the valve core to move up and down or rotate within the valve seat. The actuator can be manual, electric, pneumatic, or hydraulic, used to achieve precise control of the valve core's position. Seals prevent fluid leakage inside the valve and are typically installed at the connections between the valve core and valve seat, and between the valve stem and valve body.
[0003] While existing valve bodies offer numerous advantages during use, they still suffer from several drawbacks. Their guidance of fluid flow within the valve body is inadequate. As the fluid flows past the valve core, turbulence and pressure loss occur inside the valve body, resulting in insufficient flow regulation and impacting energy efficiency. Utility Model Content
[0004] To address the problems in the prior art, this utility model provides a valve body with adjustable flow rate.
[0005] The technical solution adopted by this utility model to solve its technical problem is an adjustable flow valve body, including a valve body body, a fixing ring, an adjusting shaft, and a clamping frame. An extension tube is provided on one outer wall of the valve body body, a bearing seat is welded to one inner wall of the extension tube, a drive rod is provided inside the bearing seat, a fixing ring is screwed to one inner wall of the extension tube, a fixing frame is welded to the inner wall of the fixing ring, an adjusting shaft is provided on one outer wall of the fixing frame, a clamping frame arranged in a circular array is provided on the outer side of the adjusting shaft, a flow guide plate is riveted to one inner wall of the clamping frame, a combination groove is opened on one outer wall of the adjusting shaft, a matching groove arranged in a circular array is opened on the outer wall of the adjusting shaft, and a matching block is slidably installed inside the matching groove.
[0006] By adopting the above technical solution, external fluid enters the interior through the lower end of the extension pipe and is guided into the valve body by the guide vane. The guide vane effectively guides the fluid, enhancing the interaction between the fluid and the valve core inside the valve body, thereby achieving more precise flow regulation. When the operator rotates the drive rod clockwise, the bearing seat ensures the stability of the drive rod's rotation position, which in turn drives the adjusting shaft to rotate synchronously through the combined groove. At this time, the clamping frame and the fixing frame rotate relative to each other, causing the guide vane to bend outside the adjusting shaft. The bending shape of the guide vane can be controlled by controlling the deviation angle, guiding the fluid to flow along the required trajectory. This ensures that the fluid flow trajectory conforms to different valve cores, effectively reducing turbulence and pressure loss within the valve body, and improving the flow regulation performance and energy utilization efficiency of the valve body.
[0007] Specifically, a damping bearing is interference-fitted inside the bearing housing, and the drive rod is interference-fitted to the inner ring of the damping bearing. The outer wall of one end of the drive rod and the inner wall of the combined groove are both rectangular in shape, and the end of the drive rod is located inside the combined groove.
[0008] By adopting the above technical solution, the damping bearing and bearing housing can ensure the stable support of the drive rod and provide rotational resistance to the drive rod, ensuring stable and reliable power transmission. Furthermore, the cooperation between the drive rod and the combined groove can accurately transmit torque, making the rotation control of the regulating shaft more precise and ensuring the accuracy and stability of flow regulation.
[0009] Specifically, the fixing frame is interference-fitted with a support bearing on the outer wall of the side facing the adjusting shaft, and one end of the adjusting shaft is interference-fitted with the inner ring of the support bearing.
[0010] By adopting the above technical solution, the support bearing provides good rotational support for the adjusting shaft, reduces friction and shaking when the adjusting shaft rotates, and improves the smoothness and stability of the adjusting shaft rotation.
[0011] Specifically, the upper outer wall of the fitting block is welded to the lower outer wall of the clamping frame. A spring seat is provided on one side of the outer wall of the fitting block and one side of the inner wall of the fitting groove. A support spring for maintaining the usage position is placed inside the spring seat, and the fitting block is elastically connected to the inner wall of the fitting groove through the support spring.
[0012] By adopting the above technical solution, the interlocking block and interlocking groove are used to maintain the stability of the movement trajectory of the clamping frame outside the adjustment shaft, and to compensate for the dimensional changes when the guide vane bends, ensuring that the guide vane can bend. When the adjustment shaft is reset after rotation, the elastic force of the support spring can push the interlocking block and clamping frame to reset, thereby facilitating the quick and accurate adjustment of the position and angle of the guide vane. The guide vane is designed with copper alloy material, which has good elasticity after appropriate heat treatment and can recover after bending, ensuring the reliability and stability of the guide vane.
[0013] Specifically, the fixing frame is arranged in a circular array, and the guide vane is riveted to the inside of the fixing frame at the outer wall of the end opposite to the clamping frame.
[0014] By adopting the above technical solution, the fixing frame is used to fix the guide vanes, so that the guide vanes are evenly distributed around the adjusting shaft, which can effectively guide the fluid to flow evenly, reduce the turbulence and pressure loss of the fluid, and fix the two ends of the guide vanes by the fixing frame and the clamping frame to ensure that the guide vanes can work stably under the impact of fluid.
[0015] Specifically, the outer wall of the adjusting shaft is screwed with a retaining ring. The retaining ring has a hollow design. The inner circle size of the retaining ring is larger than the size of the combination groove. The position of the retaining ring corresponds to the position of the fitting groove.
[0016] By adopting the above technical solution, the blocking ring will not obstruct the combination groove, ensuring the normal driving rotation function of the drive rod on the adjustment shaft. In addition, the blocking ring can block the fitting groove, ensuring that the movement trajectory of the fitting block inside the fitting groove is controlled.
[0017] Specifically, the outer wall of the adjusting shaft is provided with equally spaced parallel sliding grooves, and the lower end of the guide vane is riveted to equally spaced parallel sliders, which are slidably installed inside the sliding grooves.
[0018] By adopting the above technical solution, the inner wall dimensions of the multiple layers of the chute are different, and together with the slider, it can provide a stable moving track for the guide vane, so that the guide vane can move smoothly and stably when the position is adjusted with the clamping frame, ensuring that the bending shape of the guide vane is controlled, and the chute and slider can further reinforce the overall shape of the guide vane, ensuring the shape stability of the guide vane during the fluid guiding process.
[0019] The beneficial effects of this utility model are:
[0020] (1) The adjustable flow valve body of this utility model allows the fluid to enter the valve body after being guided by the guide plate. The guide plate can effectively guide the fluid and enhance the interaction between the fluid and the valve core inside the valve body, thereby enabling more precise flow regulation.
[0021] (2) The adjustable flow valve body of this utility model can control the bending shape of the guide vane by controlling the deviation angle, so as to guide the fluid to flow in the required trajectory, and can ensure that the flow trajectory of the fluid conforms to different valve cores. It can effectively reduce the turbulence and pressure loss of the fluid in the valve body, and improve the flow regulation performance and energy utilization efficiency of the valve body.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0029] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the adjustable flow valve body of this utility model includes a valve body 1, a fixing ring 2, an adjusting shaft 3, and a clamping frame 4. An extension tube 11 is provided on one outer wall of the valve body 1. A bearing seat 12 is welded to one inner wall of the extension tube 11. A drive rod 13 is provided inside the bearing seat 12. A fixing ring 2 is screwed to one inner wall of the extension tube 11. A fixing frame 22 is welded to the inner wall of the fixing ring 2. An adjusting shaft 3 is provided on one outer wall of the fixing frame 22. A clamping frame 4 with a circular array is provided on the outer side of the adjusting shaft 3. A flow guide plate 42 is riveted to one inner wall of the clamping frame 4. A combination groove 35 is opened on one outer wall of the adjusting shaft 3. A fitting groove 32 with a circular array is opened on the outer wall of the adjusting shaft 3. A fitting block 41 is slidably installed inside the fitting groove 32.
[0030] In use, external fluid enters the interior through the lower end of the extension pipe 11 and is guided by the guide vane 42 before entering the valve body 1. The guide vane 42 effectively guides the fluid, enhancing the interaction between the fluid and the valve core inside the valve body 1, thereby achieving more precise flow regulation. When the operator rotates the drive rod 13 clockwise, the bearing seat 12 ensures the stability of the rotation position of the drive rod 13, which in turn drives the adjusting shaft 3 to rotate synchronously through the combination groove 35. At this time, the clamping frame 4 and the fixing frame 22 rotate relative to each other, causing the guide vane 42 to bend outside the adjusting shaft 3. The bending shape of the guide vane 42 can be controlled by controlling the deviation angle to guide the fluid to flow along the required trajectory. This ensures that the fluid flow trajectory conforms to different valve cores, effectively reducing turbulence and pressure loss of the fluid in the valve body 1, and improving the flow regulation performance and energy utilization efficiency of the valve body 1.
[0031] To dampen rotation, for example, such as Figure 2 As shown, a damping bearing is interference-fitted inside the bearing housing 12, and the drive rod 13 is interference-fitted inside the inner ring of the damping bearing. The outer wall of one end of the drive rod 13 and the inner wall of the combination groove 35 are both rectangular in shape, and the end of the drive rod 13 is located inside the combination groove 35.
[0032] In use, the damping bearing, together with the bearing housing 12, can ensure the stable support of the drive rod 13 and provide rotational resistance to the drive rod 13, ensuring that the drive rod 13 transmits power stably and reliably. Furthermore, the cooperation between the drive rod 13 and the combination groove 35 can accurately transmit torque, making the rotation control of the regulating shaft 3 more precise and ensuring the accuracy and stability of flow regulation.
[0033] To maintain the rotational position, for example, such as Figure 3 As shown, a support bearing 21 is interference-fitted onto the outer wall of the fixing bracket 22 facing the adjusting shaft 3, and one end of the adjusting shaft 3 is interference-fitted onto the inner ring of the support bearing 21.
[0034] During use, the support bearing 21 provides good rotational support for the adjusting shaft 3, reduces friction and shaking when the adjusting shaft 3 rotates, and improves the smoothness and stability of the adjusting shaft 3 rotation.
[0035] To maintain the usage location, for example, such as Figure 4 As shown, the upper outer wall of the fitting block 41 is welded to the lower outer wall of the clamping frame 4. A spring seat is provided on one side of the outer wall of the fitting block 41 and one side of the inner wall of the fitting groove 32. A support spring 33 for maintaining the position is placed inside the spring seat, and the fitting block 41 is elastically connected to the inner wall of the fitting groove 32 through the support spring 33.
[0036] In use, the fitting block 41 and the fitting groove 32 are used to maintain the stability of the movement trajectory of the clamping frame 4 outside the adjusting shaft 3, and to compensate for the dimensional changes of the guide vane 42 when it bends, ensuring that the guide vane 42 can bend. When the adjusting shaft 3 returns to its original position after rotation, the elastic force of the support spring 33 can push the fitting block 41 and the clamping frame 4 to return to their original position, thereby facilitating quick and accurate adjustment of the position and angle of the guide vane 42. The guide vane 42 is made of copper alloy material, which has good elasticity after appropriate heat treatment and can recover after bending, ensuring the reliability and stability of the guide vane 42. The spring seat adopts a cylindrical shape design, and the two ends of the support spring 33 are respectively embedded in the two spring seats. The depth of the spring seat is less than the free length of the support spring 33, which is used to ensure that the support spring 33 can be in a compressed state and provide a return elastic force.
[0037] To maintain the usage location, for example, such as Figure 3 As shown, the fixing frame 22 is arranged in a circular array, and the guide vane 42 is riveted to the inside of the fixing frame 22 at the outer wall opposite to the clamping frame 4.
[0038] In use, the fixing frame 22 is used to fix the guide vane 42, so that the guide vane 42 is evenly distributed around the adjusting shaft 3, which can effectively guide the fluid to flow evenly, reduce the turbulence and pressure loss of the fluid, and fix the two ends of the guide vane 42 by the fixing frame 22 and the clamping frame 4 to ensure that the guide vane 42 can work stably under the impact of fluid.
[0039] To restrict the location of use, for example, such as Figure 4 As shown, the outer wall of the adjusting shaft 3 is screwed with a blocking ring 34. The blocking ring 34 has a hollow design. The inner circle size of the blocking ring 34 is larger than the size of the combination groove 35. The position of the blocking ring 34 corresponds to the position of the fitting groove 32.
[0040] During use, the blocking ring 34 will not obstruct the combination groove 35, ensuring that the drive rod 13 drives the adjustment shaft 3 to rotate normally. In addition, the blocking ring 34 can block the fitting groove 32, ensuring that the movement trajectory of the fitting block 41 inside the fitting groove 32 is controlled.
[0041] To limit the rotation angle, for example, such as Figure 3 As shown, the outer wall of the adjusting shaft 3 is provided with equally spaced parallel sliding grooves 31, and the lower end of the guide vane 42 is riveted to equally spaced parallel sliding blocks 43, which are slidably installed inside the sliding grooves 31.
[0042] During use, the inner wall dimensions of the multiple layers of grooves 31 are different, and together with the slider 43, they can provide a stable moving track for the guide vane 42, so that the guide vane 42 can move smoothly and stably when the position is adjusted with the clamp 4, ensuring that the bending shape of the guide vane 42 is controlled. Furthermore, the grooves 31 and the slider 43 can further reinforce the overall shape of the guide vane 42, ensuring the shape stability of the guide vane 42 during the fluid guidance process.
[0043] When this utility model is in use, external fluid flows into the valve body 1 from the lower end of the extension tube 11. Under the guidance of the guide plate 42, it enters the valve body 1 in an orderly manner. The presence of the guide plate 42 enhances the interaction between the fluid and the valve core inside the valve body 1, laying the foundation for precise flow regulation.
[0044] When the operator rotates the drive rod 13 clockwise, the damping bearing inside the bearing seat 12 provides stable support and rotational resistance for the drive rod 13, thereby driving the adjusting shaft 3 to rotate synchronously. When the adjusting shaft 3 rotates, it rotates together with the clamping frame 4 distributed in a circular array on its outer side, and the clamping frame 4 and the fixed frame 22 rotate relative to each other.
[0045] When the guide vane 42 bends and deforms, the fitting block 41 slides in the fitting groove 32 to compensate for the dimensional changes of the guide vane 42 when it bends, ensuring that the guide vane 42 is bendable and that the clamping frame 4 can maintain a stable movement trajectory during the rotation of the adjusting shaft 3. At the same time, the slider 43 at the lower end of the guide vane 42 slides in the groove 31 on the outer wall of the adjusting shaft 3. Multiple grooves 31 of different sizes cooperate with the slider 43 to provide a stable movement track for the guide vane 42, so that the guide vane 42 can be bent into the required shape according to the controlled deviation angle, guide the fluid to flow in a specific trajectory, and fit different valve cores.
[0046] When it is necessary to restore the initial position of the guide vane 42, the drive rod 13 is rotated counterclockwise, and the adjusting shaft 3 rotates in the opposite direction. At this time, the elastic force of the support spring 33 pushes the interlocking block 41 and the clamping frame 4 to reset, and the guide vane 42 returns to its original state under its own elastic cooperation.
[0047] It should be noted that this utility model is a valve body with adjustable flow rate. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
