Technical Field
[0001] The present invention relates to the technical field of flow regulation, and more particularly to a refrigeration mechanism with a flow regulation function and a regulation method. Background Art
[0002] In industrial production environments, refrigeration systems are often required to maintain a stable temperature within a plant, especially in high-temperature working environments. To ensure the smooth progress of the production process, the refrigeration system must be able to efficiently adjust the temperature to meet varying load requirements. However, in existing technologies, refrigerant flow regulation in refrigeration systems typically relies on fixed flow rates or simple control operations, which cannot be flexibly adjusted to meet varying temperature requirements. In particular, during the production process, the heat load of the plant may fluctuate significantly. This requires the refrigeration system to be able to automatically or flexibly adjust the refrigerant flow to achieve the optimal cooling effect under various operating conditions. In addition, in certain specific situations, the cooling effect of the refrigeration device directly affects the safety and working efficiency of production equipment. Especially when processing high-temperature materials or performing precision processing, if the refrigerant flow cannot be accurately adjusted, it is easy to cause overcooling or overheating, thereby affecting the normal operation of the equipment and even causing damage. Existing refrigeration systems usually use fixed flow adjustment or simple control methods, which not only increases the difficulty of operation, but may also cause slow system response and failure to adapt to environmental temperature changes in a timely manner.

[0017] The present invention is described in detail below.
[0018] like Figure 1-Figure 5 As shown: on the one hand: The present invention provides a refrigeration mechanism with a flow regulating function, comprising a refrigerator 2, a cooling mechanism, an output pipe 3 and a circulation pipe 4 respectively connected to the cooling mechanism and the refrigerator 2, and a regulating mechanism provided on the output pipe 3 and used to regulate the flow of the refrigerant; The cooling mechanism includes a guide plate 6, a cooling pipe 8 surrounding the guide plate 6, and a fan 7 arranged outside the guide plate 6; the cooling pipe 8 is connected to the output pipe 3 and the circulation pipe 4 respectively; The refrigerator 2 and the cooling mechanism are mounted on the base 1, and the cooling mechanism is mounted on the base 1 through the mounting plate 5; The adjustment mechanism includes a connecting sleeve 9, an adjusting sleeve 10 coaxially connected to the connecting sleeve 9 and rotatably engaged with the connecting sleeve 9, a control sleeve 13 sleeved within the connecting sleeve 9 and provided with a through slot 14, a sealing sleeve 12 located between the control sleeve 13 and the connecting sleeve 9 and coaxially sleeved outside the control sleeve 13, a screw 15 sleeved within the control sleeve 13 and threadedly engaged with the connecting sleeve 9, and a positioning mechanism for positioning and limiting the connecting sleeve 9 and the adjusting sleeve 10; Specifically, the output pipe 3 includes a pipe 1 connected to the cooling pipe 8 and a pipe 2 connected to the refrigerator 2. The pipes 1 and 2 are connected by an adjustment mechanism, wherein the adjustment sleeve 10 is connected to the pipe 1 and is sleeved on the outside of the pipe 1, and the connecting sleeve 9 is sleeved on the outside of the pipe 2. Furthermore, the first tube and the adjustment sleeve 10 are slidably fitted around their axial direction and are in communication with each other; the second tube is located between the connecting sleeve 9 and the control sleeve 13; the first tube and the adjustment sleeve 10, and the second tube and the connecting sleeve 9 are in a sealed fit; the second tube is sheathed on the outside of the control sleeve 13 and is in communication with the through groove 14 provided on the control sleeve 13, thereby forming a flow channel for the refrigerant to flow; The sealing sleeve 12 is installed on the inner side of the connecting sleeve 9 and is slidably matched with the control sleeve 13; When adjusting the refrigerant flow, the positioning mechanism releases the positioning and limiting of the connecting sleeve 9 and the adjusting sleeve 10, and then controls the adjusting sleeve 10 to rotate around its axial direction. Since the adjusting sleeve 10 is connected to the control sleeve 13 through the screw 15, the control sleeve 13 and the sealing sleeve 12 slide together along the axial direction of the screw 15, so that the control sleeve 13 will move along the axial direction of the screw 15; thereby, the area of the through groove 14 is changed, and the passage space of the refrigerant is changed, thereby realizing the adjustment of the refrigerant flow. Through this setting, the refrigerant flow can be accurately adjusted according to demand, thereby adapting to different production loads and temperature requirements, and improving the flexibility and efficiency of the refrigeration mechanism.
[0019] In some possible embodiments, in order to effectively realize the rotation and limited fixation of the adjustment sleeve 10 and the connecting sleeve 9 through the positioning mechanism; the positioning mechanism includes a mounting sleeve 16 that is sleeved on the outside of the connecting sleeve 9 and connected to the end of the adjustment sleeve 10 close to the connecting sleeve 9, a positioning rod 17 that is arranged radially along the mounting sleeve 16 and has one end passing through the mounting sleeve 16, a limiting sleeve 19 that is sleeved on the outside of the connecting sleeve 9 and abuts against the outer side of the positioning rod 17 away from the connecting sleeve 9, and a limiting mechanism that is sleeved on the outside of the connecting sleeve 9 and cooperates with the limiting sleeve 19; one end of the positioning rod 17 passes through the mounting sleeve 16 and abuts against the outer side of the connecting sleeve 9; The limiting sleeve 19 slides with the connecting sleeve 9 along the axial direction of the connecting sleeve 9; the positioning rod 17 is elastically connected to the mounting sleeve 16; When the connecting sleeve 9 and the adjusting sleeve 10 are fixed in position, one end of the positioning rod 17 will pass through the mounting sleeve 16 and abut against the outer side surface of the connecting sleeve 9 under the restriction of the mounting sleeve 16, thereby effectively limiting the rotation of the two. When flow adjustment is required, the limiting sleeve 19 will move along its axial direction to the side away from the adjusting sleeve 10. At this time, the inner side of the limiting sleeve 19 will no longer restrict the outer end surface of the positioning rod 17. Since the positioning rod 17 and the mounting sleeve 16 are elastically connected, the positioning rod 17 will no longer abut against the outer side surface of the connecting sleeve 9 under the elastic force, and the rotation restriction of the adjusting sleeve 10 and the connecting sleeve 9 will be cancelled; then the adjusting sleeve 10 is controlled to rotate around its axial direction, and the control sleeve 13 is driven to move along its axial direction by the screw 15, thereby changing the space in the through groove 14 that the refrigerant can pass through, thereby realizing the adjustment of the refrigerant flow; After the adjustment is completed, the limiting sleeve 19 is controlled to move toward the side close to the adjusting sleeve 10 , and the inner side surface of the limiting sleeve 19 abuts against the outer end surface of the positioning rod 17 , thereby fixing the connecting sleeve 9 and the adjusting sleeve 10 again.
[0020] In some possible embodiments, in order to effectively achieve axial adjustment of the limit sleeve 19 along the screw 15 through the limit mechanism, and to fix the unlocking sleeve 22 after the adjustment is in place; the limit mechanism includes an unlocking sleeve 22 that is sleeved on the outside of the connecting sleeve 9 and is located on the side of the limit sleeve 19 away from the adjustment sleeve 10, and an elastic part that is installed on the side of the limit sleeve 19 close to the unlocking sleeve 22 and is plugged into the unlocking sleeve 22; a slot that is plugged into the elastic part is provided on the unlocking sleeve 22; the unlocking sleeve 22 is rotatably matched with the connecting sleeve 9.
[0021] Specifically, when flow regulation is required, the unlocking sleeve 22 is controlled to rotate around the axis of the connecting sleeve 9 so that one end of the elastic member is aligned with the slot. Then, the unlocking sleeve 22 is controlled to move away from the adjusting sleeve 10 and the elastic member is controlled to be inserted into the slot so that the elastic member is engaged with the slot. At this time, the elastic member is in a compressed state, and the limiting sleeve 19 will not restrict the positioning rod 17, so that the positioning rod 17, which was originally in a compressed state, will no longer abut against the outer side surface of the connecting sleeve 9 when the elastic force is restored, and then the connecting sleeve 9 and the adjusting sleeve 10 are no longer fixed in position. After the adjustment is completed, the elastic member is separated from the slot, and the elastic member will recover from the compressed state to the initial state, so that the unlocking sleeve 22 moves toward the side close to the adjustment sleeve 10 and abuts against the outer end surface of the positioning rod 17, thereby realizing the limiting fixation of the adjustment sleeve 10 and the connecting sleeve 9 again.
[0022] In some possible embodiments, in order to effectively achieve the positioning of the unlocking sleeve 22 through the cooperation of the elastic member and the slot; the elastic member includes a push rod 20 arranged axially along the connecting sleeve 9 in the longitudinal direction and connected to the limiting sleeve 19 at one end, a stopper 21 installed at the other end of the push rod 20, a limiting block 24 sleeved on the outside of the push rod 20, and a compression spring 31 connected to the limiting sleeve 19 at one end and sleeved on the outside of the push rod 20; the slot includes a clearance groove 23 and a limiting groove 25 in an arc shape and connected to the clearance groove 23 at one end, the center of the limiting groove 25 is concentric with the center of the unlocking sleeve 22; the other end of the compression spring 31 abuts and cooperates with the unlocking sleeve 22; The compression spring 31 provides the necessary elastic force to ensure that the limiting sleeve 19 can remain stable during operation and prevent the limiting sleeve 19 from being displaced or loosened due to external forces, thereby enhancing the stability of the limiting sleeve 19 and ensuring reliability and accuracy; A gap is formed between the stopper 21 and the limiting block 24. When in use, the stopper 21 is first passed through the clearance groove 23, and then the unlocking sleeve 22 is rotated so that the push rod 20 is located in the limiting groove 25. The width of the limiting groove 25 is smaller than the width of the clearance groove 23, and the stopper 21 will not be able to pass through the limiting groove 25. In this way, after the limiting sleeve 19 moves toward the unlocking sleeve 22, it will not directly return to its original position under the elastic force, thereby meeting the adjustment requirements of the adjustment sleeve 10; After the adjusting sleeve 10 is adjusted to the right position, the unlocking sleeve 22 will rotate in the opposite direction around its axis, and the stopper 21 will enter the clearance groove 23. Then, under the elastic force, the limiting sleeve 19 is controlled to move toward the side of the positioning rod 17, and its inner side surface abuts against the outer side of the positioning rod 17. The design of the clearance groove 23 allows the limit sleeve 19 to pass through the stop block 21 and the limiting block 24 smoothly when moving, reducing the movement resistance and avoiding the jamming phenomenon caused by collision, thereby improving the flexibility and stability of the system and ensuring smooth and barrier-free operation during the adjustment process.
[0023] In some possible embodiments, in order to enable the positioning rod 17 to abut against the outer side of the connecting sleeve 9 under the elastic force; a return spring 28 is provided on the outer side of the mounting sleeve 16, and the return spring 28 is sleeved on the outer side of the positioning rod 17; the end of the return spring 28 close to the mounting sleeve 16 is connected and fixed to the mounting sleeve 16, and the other end of the return spring 28 is connected to the end of the positioning rod 17 close to the limiting sleeve 19; a plurality of groups of positioning grooves 18 for use with the positioning rod 17 are provided on the outer side of the connecting sleeve 9, and the positioning grooves 18 are multiple groups and are arranged at equal intervals along the circumference of the connecting sleeve 9; specifically, the number of positioning grooves 18 will be greater than the number of positioning rods 17; A plurality of guide grooves 30 are provided on the outer side of the connecting sleeve 9 and are slidably matched with the limiting sleeve 19. A guide block 29 is provided on the end of the limiting sleeve 19 away from the adjusting sleeve 10 and is slidably matched with the guide grooves 30. The cooperation between the guide block 29 and the guide groove 30 will limit the sliding direction of the limit sleeve 19, so that the limit is only along the axial direction of the screw 15 to achieve sliding cooperation with the connecting sleeve 9; The return spring 28 can automatically restore the positioning rod 17 to its original position after adjustment, ensuring the precise positioning of the positioning rod 17 and preventing positioning deviations due to operational errors. At the same time, it improves the stability and reliability of the adjustment and ensures the continuous and efficient operation of the adjustment system during use.
[0024] In some possible embodiments, the control sleeve 13 includes a sleeve-shaped body that is sleeved within the connecting sleeve 9, and an end cap 26 that is disposed on a side of the body away from the adjusting sleeve 10 and connected to the screw 15; the through slots 14 are disposed on the body in multiple groups, with the multiple groups of through slots 14 being disposed outside the body and communicating with the interior of the body; and the multiple groups of through slots 14 are spaced apart along the circumference of the body. A guide rod 27 is provided on the outside of the control sleeve 13 and along the axial direction of the control sleeve 13 to slide with the sleeve 12; the height of the sleeve 12 along the axial direction of the connecting sleeve 9 is less than the length of the through slot 14 along the axial circumferential direction of the connecting sleeve 9; The guide rod 27 is provided on the end cover 26 and is axially arranged along the length direction of the screw 15 so that the control sleeve 13 can effectively move along the axial direction of the screw 15 under the adjustment of the adjustment sleeve 10; The sleeve 12 is annular and is mounted on the outside of the body. The adjusting sleeve 10 is rotated to make the end cover 26 connected to the screw 15 slide along the axial direction of the screw 15, thereby driving the body to move. The sleeve 12 is fixedly mounted on the inner side of the connecting sleeve 9. The body and the sleeve 12 move relative to each other, and the sleeve 12 changes the space for the refrigerant to pass through the through groove 14, thereby adjusting the refrigerant flow rate. Specifically, there are multiple groups of guide rods 27; multiple groups of guide holes corresponding to the guide rods 27 are provided on the sleeve 12; the guide rods 27 are arranged along the axial direction of the screw 15 and are arranged on the side of the end cover 26 close to the body, thereby effectively guiding the movement of the control sleeve 13; The cooperation between the guide block 29 and the guide groove 30 enables the limit sleeve 19 to slide smoothly in the connecting sleeve 9; it avoids the jamming problem caused by inaccurate positioning or excessive friction, ensures the precise positioning and smooth movement of the limit sleeve 19, and improves the accuracy of the adjustment process.
[0025] In some possible embodiments, a bracket 11 is provided in the adjusting sleeve 10, which is threadedly connected to the screw 15 and connected to the inner side wall of the adjusting sleeve 10; a limit block with an L-shaped cross-section is provided at one end of the adjusting sleeve 10 close to the connecting sleeve 9; a slot is formed between the limit block and the mounting sleeve 16; the end of the adjusting sleeve 10 close to the connecting sleeve 9 is located in the slot; this arrangement will effectively ensure the connection between the connecting sleeve 9 and the adjusting sleeve and enable sliding fit.
[0026] The present invention uses the refrigerator 2 to transport the refrigerant to the cooling pipe 8 through the output pipe 3 and conduct the temperature of the cooling pipe 8 through multiple sets of guide plates 6. The fan 7 blows out cold air for cooling, and then the refrigerant circulates to the refrigerator through the circulation pipe 4. This design effectively realizes the circulation of the refrigerant and the generation of cold air. Through the temperature conduction of the cooling pipe 8 and the auxiliary effect of the blowing fan 7, continuous temperature control can be achieved, ensuring that the temperature in the space is always maintained in an appropriate range, providing an efficient and stable cooling effect.
[0027] The present invention drives multiple groups of give way grooves 23 to move by rotating the unlocking sleeve 22, thereby releasing the contact with the block 21, and pushing the limit sleeve 19 to make the push rod 20 slide in the give way groove 23 to adjust the refrigerant flow. The unlocking sleeve 22 is rotated to make multiple groups of limiting blocks 24 pass through the give way grooves 23 and slide to the bottom of the limiting groove 25, squeezing the compression spring 31. Through the threaded cooperation of the adjusting sleeve 10 and the bracket 11, the sliding of the control sleeve 13 and the sealing sleeve 12 is achieved, thereby changing the blocking area of the through groove 14 and adjusting the flow space of the refrigerant. This design enables the refrigerant flow to be precisely adjusted according to demand, thereby adapting to different production loads and temperature requirements, and improving the flexibility and efficiency of the refrigeration system.
[0028] In the present invention, the cooperation between the positioning rod 17 and the limiting sleeve 19 accurately limits the rotation range of the adjustment sleeve 10, ensuring that each component is always in the correct position during the flow adjustment process. The cooperation between the positioning rod 17 and the positioning groove 18 realizes the stable positioning of the adjustment sleeve 10, and the cooperation between the limiting sleeve 19 and the push rod 20 effectively prevents the misoperation and deviation of the components; through the design of the compression spring 31 and the unlocking sleeve 22, it is ensured that when the adjustment is completed, the adjustment sleeve 10 can be accurately restored to its original position, while avoiding structural damage caused by improper operation. This design not only ensures stability and precision during the adjustment process.
[0029] on the other hand: The present invention provides a method for regulating a refrigeration mechanism with a flow regulating function based on the above-mentioned method; specifically, the method includes: When the refrigerant flow needs to be adjusted, the limiting mechanism releases the limit between the unlocking sleeve 22 and the limiting sleeve 19, pushing the limiting sleeve 19 to move closer to the unlocking sleeve 22; After the limiting sleeve 19 moves to the specified position, the limiting mechanism will release the limit on the unlocking sleeve 22 and the limiting sleeve 19. At this time, the limiting sleeve 19 no longer abuts against the outer side of the positioning rod 17. The rotating adjustment sleeve 10 drives the control sleeve 13 to move axially along the screw 15, changing the blocking area of the multiple groups of through grooves 14, thereby changing the flow space of the refrigerant and adjusting the flow rate.
[0030] When the plurality of limiting blocks 24 pass through the give way slots 23, the unlocking sleeve 22 is rotated again to allow the plurality of push rods 20 to slide in the limiting slots 25 and squeeze the compression spring 31. The limit sleeve 19 is limited by the plurality of limiting blocks 24 top surfaces abutting against the bottom surface of the unlocking sleeve 22. The positioning rod 17 is pulled outward by the plurality of return springs 28 to disengage the positioning slot 18, thereby releasing the limit of the adjusting sleeve 10. The rotating adjusting sleeve 10 is threadedly engaged with the screw 15 through the bracket 11, and the control sleeve 13 is driven to slide along the sleeve 12 to change the blocking area of the plurality of through slots 14, thereby changing the flow space of the refrigerant, thereby adjusting the flow rate.
[0031] After the adjustment is completed, the unlocking sleeve 22 is rotated to make the multiple groups of push rods 20 slide out of the limiting groove 25 and move into the making way groove 23, releasing the abutment between the multiple groups of limiting blocks 24 and the unlocking sleeve 22, and the limiting sleeve 19 is reset and pushed by the multiple groups of compression springs 31 to abut the top of the multiple groups of positioning rods 17, pushing the multiple groups of positioning rods 17 to be inserted into the positioning groove 18, positioning the adjustment sleeve 10, and when the multiple groups of blocks 21 are out of the making way groove 23, the unlocking sleeve 22 is rotated to make the multiple groups of blocks 21 abut against the top surface of the unlocking sleeve 22, limiting the limiting sleeve 19.
[0032] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
