Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration units, and in particular to an integrated refrigeration unit. Background Art

[0002] A refrigeration unit is usually composed of multiple refrigerators, and each refrigerator is connected to the same cooling circuit through pipes. During the refrigeration process, the right number of refrigerators can be started according to the refrigeration needs. On the basis of meeting the usage needs, it can fully save energy and improve resource utilization. It is usually used in industrial refrigeration equipment or air-conditioning systems of large commercial buildings.

[0003] At present, during the operation of a refrigeration unit, the on and off of the refrigeration machine pipeline is usually controlled by a separate control valve. During the opening and closing process, manual control or a corresponding automatic control device is required to control the corresponding control valve to complete the opening and closing work. At the same time, during long-term repeated use, it is easy to cause incomplete closure between the branch pipe and the main pipe, allowing gas to enter the branch pipe that originally needs to be closed, thereby affecting the working efficiency and stability of the refrigeration unit. Therefore, the present invention provides an integrated refrigeration unit. Summary of the invention

[0004] The main purpose of the present invention is to provide an integrated refrigeration unit. When the branch pipe and the main pipe cannot be completely closed, the liquid inside the liquid storage chamber is introduced into the interior of the piston box two by the gravity of the blocking block and the counterweight piston, and the piston two and the connecting column two are moved synchronously, so that the blocking block conflicts with the inner end and the inner end surface of the valve body channel, thereby achieving the effect of completely closing the branch pipe, thereby improving the continuous working efficiency and working stability of the entire refrigeration unit.

[0005] To achieve the above-mentioned object, the present invention provides an integrated refrigeration unit, comprising a base, wherein the two sides of the base are respectively connected with a main pipeline and branch pipelines distributed at equal intervals along the circumferential direction of the base side, and valve body channels corresponding to the branch pipelines are opened at equal intervals along the circumferential direction on the circumferential surface of the base, a blocking seat is slidably provided inside the valve body channel, and a valve stem is connected to the top of the blocking seat through a bearing, a liquid storage cavity is fixed at the middle position of the top end of the blocking seat, and a counterweight piston is slidably provided on the upper half of the liquid storage cavity; A piston box 1 connected to the liquid storage chamber is fixedly connected to the bottom of both sides of the liquid storage chamber, and a piston 1 is slidably connected inside the piston box 1, and a connecting column 1 extending to the outside of the piston box 1 is fixed at equal intervals along its length direction on the outside of the piston 1, and the end of the connecting column 1 is connected to a connecting block, and an extension block extending to the outside of the blocking seat is fixed on the outside of the connecting block, and limiting sliders are fixed on both sides of the end of the extension block, and sensors are installed on the inner side walls of the blocking seat on both sides of the extension block; The bottom end of the liquid storage chamber is connected to a conduit at equal intervals, and a valve is installed on the liquid storage chamber, the end of the conduit is connected to a piston box 2, and the interior of the piston box 2 is slidably connected to a piston 2, and a connecting column 2 extending to the outside of the piston box 2 is fixedly connected to the side of the piston 2, and a blocking block is fixedly connected to the end of the connecting column 2.

[0006] Preferably, the outer ends of the valve body channels are rotatably connected to gear plates, and a threaded hole matching the external thread of the valve stem is provided at the middle position of the gear plate, and the top end of the valve stem passes through the threaded hole.

[0007] Preferably, an annular bracket is rotatably connected to the base on the side of the valve body channel, and an arc-shaped rack with a quarter of the circumference of the annular bracket is fixedly connected to the side of the annular bracket along its circumferential direction, and the arc-shaped rack is meshed with the gear plate.

[0008] Preferably, trapezoidal sliding grooves for the extension block to slide are provided on both sides of the valve body channel, and limiting sliding grooves for the limiting sliding block to slide are provided on both sides of the trapezoidal sliding groove.

[0009] Preferably, a ring gear is fixed on one side of the base, and the ring gear and the base are driven to rotate by an external motor and a gear at an output end of the motor.

[0010] The benefits of the present invention are as follows: first, the trapezoidal sliding groove is a right-angled trapezoidal structure, and is limited by a limiting sliding groove and a limiting sliding block. Therefore, during the movement, the extension block will be stretched, so that the extension block on the inner side of the blocking seat moves toward the outer side of the blocking seat. At the same time, during the movement of the extension block, the connecting column 1 and the piston 1 are pulled, so that the liquid inside the liquid storage chamber is drawn into the interior of the piston box 1. Under normal circumstances, the blocking seat will move to the inner end of the valve body channel and conflict with the inner end surface, so the connecting block will conflict with the sensor. When the connecting block and the sensor conflict with each other, the valve is in a closed state, which means that the bus pipeline and the branch pipeline are in a completely blocked state. It is explained here that the opening condition of the valve is that the blocking seat is in the state of blocking the bus pipeline and the branch pipeline, and the blocking seat cannot completely conflict with the inner end surface. When the synchronous connecting block and the sensor cannot conflict with each other, the sensor transmits a signal to the controller, so that the controller controls the valve to open; Secondly, since the valve stem and the sealing seat are repeatedly opened and closed to connect the main pipeline and the branch pipeline, the control valve may not be completely closed due to incomplete rotation of the valve stem, causing the branch pipeline that originally needed to be closed to be in a semi-closed state. At this time, the connecting block and the sensor cannot conflict with each other, so the valve is opened, and the liquid inside the liquid storage chamber will enter the interior of the piston box two through the conduit. Then, under the action of gravity of the blocking block and the counterweight piston, the liquid inside the liquid storage chamber is introduced into the interior of the piston box two, and the piston two and the connecting column two are moved simultaneously, so that the blocking block conflicts with the inner end and the inner end face of the valve body channel, thereby achieving the effect of completely closing the branch pipeline. Then the valve is closed to maintain subsequent use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1 The present embodiment provides an integrated refrigeration unit, comprising a base 100, wherein the base 100 is respectively connected with a main pipeline 110 and branch pipelines 130 distributed at equal intervals along the circumferential direction of the side surface of the base 100, and valve body channels 120 corresponding to the branch pipelines 130 are opened at equal intervals along the circumferential direction on the circumferential surface of the base 100, a blocking seat 500 is slidably provided inside the valve body channel 120, and a valve stem 400 is connected to the top of the blocking seat 500 through a bearing, a liquid storage chamber 504 is fixed at the middle position of the top end inside the blocking seat 500, and a counterweight piston 510 is slidably provided on the upper half of the liquid storage chamber 504; In this embodiment, the bottom of both sides of the liquid storage chamber 504 is fixedly connected with a piston box 509 connected to the liquid storage chamber 504, and the piston box 509 is slidably connected with a piston 508 inside, and connecting columns 507 extending to the outside of the piston box 509 are fixed at equal intervals along its length direction on the outside of the piston 508, and the end of the connecting column 507 is connected to a connecting block 505, and an extension block 501 extending to the outside of the blocking seat 500 is fixed on the outside of the connecting block 505, and limiting sliders 502 are fixed on both sides of the end of the extension block 501, and sensors 506 are installed on the inner side walls of the blocking seat 500 on both sides of the extension block 501. When in use, during the movement of the extension block 501, the connecting column 507 and the piston 508 are pulled to move the liquid storage chamber 504. The liquid in the liquid cavity 504 is drawn into the interior of the piston box 1 509. Under normal circumstances, the blocking seat 500 will move to the inner end of the valve body channel 120 and conflict with the inner end surface. Therefore, the connecting block 505 will conflict with the sensor 506. When the connecting block 505 and the sensor 506 conflict with each other, the valve 513 is in a closed state, which means that the bus pipe 110 and the branch pipe 130 are in a completely blocked state. It is explained here that the opening condition of the valve 513 is that the blocking seat 500 is in the state of blocking the bus pipe 110 and the branch pipe 130, and the blocking seat 500 cannot completely conflict with the inner end surface. When the synchronous connecting block 505 and the sensor 506 cannot conflict with each other, the sensor 506 transmits a signal to the controller, so that the controller controls the valve 513 to open; In this embodiment, the bottom end of the liquid storage chamber 504 is connected with a conduit 514 at equal intervals, and a valve 513 is installed on the liquid storage chamber 504, the end of the conduit 514 is connected with a piston box 511, and the interior of the piston box 511 is slidably connected with a piston 512, and a connecting column 515 extending to the outside of the piston box 511 is fixedly connected to the side of the piston 512, and a blocking block 503 is fixedly connected to the end of the connecting column 515. When in use, since the valve stem 400 and the blocking seat 500 are repeatedly opened and closed to connect the bus pipeline 110 and the branch pipeline 130, it is easy to fail to fully close the control valve due to incomplete rotation of the valve stem 400, so that The branch pipeline 130 that was originally required to be closed is in a semi-closed state. At this time, the connecting block 505 and the sensor 506 cannot conflict with each other, so the valve 513 is opened, so that the liquid inside the liquid storage chamber 504 will enter the interior of the piston box 511 through the conduit 514, and then the liquid inside the liquid storage chamber 504 is introduced into the interior of the piston box 511 under the action of gravity of the blocking block 503 and the counterweight piston 510, and the piston 512 and the connecting column 515 are moved synchronously, so that the blocking block 503 conflicts with the inner end and the inner end face of the valve body channel 120, so as to achieve the effect of completely closing the branch pipeline 130, and then the valve 513 is closed to maintain subsequent use.

[0026] In this embodiment, the outer ends of the valve body channel 120 are rotatably connected to the gear plate 300, and a threaded hole matching the external thread of the valve stem 400 is opened at the middle position of the gear plate 300, and the top of the valve stem 400 passes through the threaded hole. When in use, the gear plate 300 is rotated, and the valve stem 400 is driven to rotate synchronously through the threaded hole at the middle position of the gear plate 300, so that the valve stem 400 and the sealing seat 500 move.

[0027] like Figure 1 As shown, in this embodiment, an annular bracket 200 is rotatably connected to the base 100 on the side of the valve body channel 120, and an arc-shaped rack 210 with a quarter of the circumference of the annular bracket 200 is fixedly connected to the side of the annular bracket 200 along its circumferential direction, and the arc-shaped rack 210 is meshed with the gear plate 300. When in use, 200 is fixed to the refrigeration body, and then the arc-shaped rack 210 is meshed with the gear plate 300, so that the gear plate 300 rotates during the counterclockwise rotation of the base 100.

[0028] like Figure 3 and Figure 4 As shown, in the present embodiment, trapezoidal sliding grooves 121 for sliding of the extension block 501 are provided on both sides of the valve body channel 120, and limiting grooves 122 for sliding of the limiting slider 502 are provided on both sides of the trapezoidal sliding grooves 121. When in use, the extension block 501 and the limiting slider 502 move along the outer ends of the trapezoidal sliding grooves 121 and the limiting grooves 122 toward the inner ends. Since the trapezoidal sliding grooves 121 are in a right-angle trapezoidal structure and are limited by the limiting grooves 122 and the limiting slider 502, the extension block 501 will be stretched during the movement, so that the extension block 501 on the inner side of the blocking seat 500 moves toward the outer side of the blocking seat 500.

[0029] like Figure 1 As shown, in the present embodiment, a ring gear 140 is fixed on one side of the base 100, and the ring gear 140 is driven by an external motor and a gear at the output end of the motor to rotate the ring gear 140 and the base 100. When in use, the ring gear 140 and the base 100 are driven to rotate by the external motor and the gear at the output end of the motor. Due to the rotation of the base 100, there must be a blocking seat 500 that is in the position where the valve body channel 120 opens upward when the opening or closing is completed, so that the gravity of the blocking block 503 and the counterweight piston 510 subsequently introduces the liquid inside the liquid storage chamber 504 into the interior of the piston box 2 511, and synchronously moves the piston 2 512 and the connecting column 2 515.

[0030] In summary: During the refrigeration process, the connection between each branch pipe 130 and the main pipe 110 will be opened or closed in turn according to the refrigeration demand. When closing, the ring gear 140 and the base 100 are driven to rotate by the external motor and the gear at the motor output end. Due to the rotation of the base 100, a blocking seat 500 is bound to be in the state where the valve body channel 120 opens upward when the opening or closing is completed. At the same time, the arc-shaped rack 210 is meshed with the gear plate 300, so that the base 100 rotates counterclockwise. , the gear plate 300 rotates, thereby driving the valve stem 400 to rotate through the threaded hole at the middle position of the gear plate 300 and moving toward the inner end of the valve body channel 120, and synchronously driving the blocking seat 500 to move downward. During the downward movement of the blocking seat 500, the extension block 501 and the limit slider 502 move toward the inner end along the outer end of the trapezoidal sliding groove 121 and the limit slider 122. Since the trapezoidal sliding groove 121 is a right-angled trapezoidal structure and is limited by the limit slider 122 and the limit slider 502 Therefore, during the movement, the extension block 501 is stretched, so that the extension block 501 on the inner side of the blocking seat 500 moves toward the outer side of the blocking seat 500. At the same time, during the movement of the extension block 501, the connecting column 1 507 and the piston 1 508 are pulled, so that the liquid inside the liquid storage chamber 504 is drawn into the interior of the piston box 1 509. Under normal circumstances, the blocking seat 500 will move to the inner end of the valve body channel 120 and conflict with the inner end surface, so the connecting block 505 will conflict with the sensor 506. When the sensors 506 conflict with each other, the valve 513 is in a closed state, which means that the bus pipe 110 and the branch pipe 130 are in a completely blocked state. It is explained here that the opening condition of the valve 513 is that the blocking seat 500 is in the state of blocking the bus pipe 110 and the branch pipe 130, and the blocking seat 500 cannot completely conflict with the inner end surface, and the synchronous connection block 505 and the sensor 506 cannot conflict with each other, the sensor 506 transmits a signal to the controller, so that the controller controls the valve 513 to open.
