Description

Technical Field

[0001] This utility model relates to the field of flow control device technology, and in particular to a flow control device for refrigerant pipes used in factory refrigeration. Background Technology

[0002] The refrigerant pipe flow control device for factory refrigeration is an innovative automatic control device designed to ensure the efficient operation and stability of the refrigeration system by precisely adjusting the refrigerant flow. It also solves the problem of traditional manual valves being difficult to operate due to rust, thus improving the system's automation level and ease of operation.

[0003] The manual flow control valves commonly used in existing factory refrigeration systems have certain limitations. Especially after long-term use, due to internal rust, the handle becomes difficult to turn, resulting in an inability to effectively control the flow of liquid in the refrigerant pipes. This problem is particularly prominent in low-temperature environments during winter, affecting the normal operation of the refrigeration system and increasing maintenance costs. Therefore, improvements are needed. Utility Model Content

[0004] One objective of this invention is to provide a refrigerant pipe flow control device for factory refrigeration. This invention addresses the limitations of the manual flow control valves commonly used in existing factory refrigeration systems, as mentioned in the background. In particular, after long-term use, internal rust makes the handle difficult to turn, resulting in ineffective control of the liquid transport in the refrigerant pipe. This problem is even more prominent in low-temperature environments during winter, affecting the normal operation of the refrigeration system and increasing maintenance costs.

[0005] A refrigerant pipe flow control device for factory refrigeration according to an embodiment of the present utility model includes:

[0006] A refrigerant piping assembly includes a pipe, wherein a flow control valve is fixedly installed inside the pipe, the valve has a plugging hole inside, and a mounting bracket is fixedly installed on the top of the pipe;

[0007] A flow control component, installed on top of the mounting bracket in the refrigerant pipe assembly, is used to control the flow rate of the refrigerant pipes used for refrigeration in the factory. The flow control component includes a housing, with a motor mounted on the top of the housing. A small gear is fixedly mounted on the output end of the motor, and a large gear meshes with the outside of the small gear. A rotating cylinder is fixedly mounted inside the large gear, and a screw is fixedly mounted on the bottom of the rotating cylinder. A threaded cylinder is threaded onto the lower outer end of the screw, and a support base is fixedly mounted on the bottom of the threaded cylinder. A connecting seat and a fixed seat are respectively mounted on the upper and lower ends of the support base. A guide seat is fixedly mounted on one side of the connecting seat and is movably mounted on the outside of the guide rod. A sealing post is fixedly mounted on the bottom of the fixed seat.

[0008] Preferably, a sealing ring is fixedly installed at one end of the pipe near the sealing column.

[0009] Preferably, control buttons and a control terminal are respectively provided on the outside of the box.

[0010] Preferably, ear plates are fixedly provided on both sides of the motor, and the motor and ear plates are fixed to the housing by bolts.

[0011] Preferably, the top of the motor is provided with a battery compartment, and a cover plate is rotatably provided on the top of the battery compartment.

[0012] Preferably, a handle is fixedly provided on one side of the top of the cover plate.

[0013] Preferably, the rotating drum is rotatably mounted to the housing via a bearing seat.

[0014] Preferably, the support base, the fixed base, and the connecting base are fixedly connected by bolts, the guide rod is fixedly installed inside the housing, the sealing column is movably installed inside the pipe in the refrigerant pipe assembly and is located directly above the sealing door, and the cone of the sealing column is adapted to the plugging hole.

[0015] The beneficial effects of this utility model are:

[0016] This invention effectively avoids the inconvenience of manual flow control valves by using a flow control component. During the use of refrigerant pipes for refrigeration in the factory, operators can use the control button in the flow control component to drive the motor in both forward and reverse directions. When the refrigerant pipe flow needs to be increased, the motor drives the small gear to drive the large gear, the rotating drum, and the threaded rod to rotate clockwise simultaneously. This causes the sealing column to move away from the sealing gate inside the pipe under the connection of the threaded drum and the threaded rod, and the connection of the guide seat and the guide rod. At this time, the coolant can be transported. Conversely, when the sealing column is inserted into the plug hole in the sealing gate, it can prevent the transport of coolant and reduce the gap between the sealing column and the plug hole, thereby reducing the flow rate. Thus, this device uses the control button and the motor to control the flow of the refrigerant pipe, eliminating the inconvenience caused by manually rotating the handle.

[0017] This invention uses a small gear, a large gear, and a sealing ring. The cooperation between the small gear and the large gear simulates the principle of a speed reducer, thereby reducing the output speed and increasing the output torque, thus improving the service life of the device. The sealing ring located inside the pipe can prevent coolant leakage. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1-4 A refrigerant pipe flow control device for factory refrigeration includes:

[0026] The refrigerant piping assembly 1 includes a pipe 101. A flow-control valve 103 is fixedly installed inside the pipe 101 to control the refrigerant flow. The valve 103 has a plugging hole 104 inside. By adjusting the size of the plugging hole 104, the refrigerant flow can be precisely controlled. A mounting bracket 102 is fixedly installed at the top of the pipe 101. In practical applications, when it is necessary to adjust the refrigerant flow, the operator can adjust the plugging hole 104 on the valve 103 to achieve precise control of the refrigerant flow, thereby ensuring the stability and efficiency of the refrigeration system. This device simplifies the operation process, improves the automation level of the refrigeration system, and reduces the failure rate caused by improper manual operation.

[0027] The flow control component 3 is installed on the top of the mounting bracket 102 in the refrigerant pipe assembly 1, and is used to control the flow of the refrigerant pipe for refrigeration in the plant. The flow control component 3 includes a housing 301, a motor 304 is installed on the top of the housing 301, a pinion 309 is fixedly installed at the output end of the motor 304, a large gear 310 is meshed on the outside of the pinion 309, a rotating drum 311 is fixedly installed inside the large gear 310, a screw 313 is fixedly installed at the bottom of the rotating drum 311, a threaded cylinder 314 is threaded on the lower end of the outer side of the screw 313, a support base 315 is fixedly installed at the bottom of the threaded cylinder 314, a connecting seat 317 and a fixing seat 316 are respectively installed at the upper and lower ends of the support base 315, and a guide is fixedly installed on one side of the connecting seat 317. The guide seat 318 is movably mounted on the outside of the guide rod 319. The bottom of the fixed seat 316 is fixedly equipped with a sealing column 320. The control button in the flow control component is used to drive the motor to rotate in both directions. When the refrigerant flow needs to be increased, the motor drives the small gear to drive the large gear, the rotating drum and the threaded rod to rotate clockwise at the same time. This causes the sealing column to move away from the sealing gate inside the pipe under the connection of the threaded drum and the threaded rod and the connection of the guide seat and the guide rod. At this time, the coolant can be delivered. Conversely, when the sealing column is inserted into the plug hole in the sealing gate, it can prevent the delivery of coolant and reduce the gap between the sealing column and the plug hole to reduce the flow. Thus, the device uses the control button and the motor to control the flow of the refrigerant pipe.

[0028] Example 1: A sealing ring 2 is fixedly installed inside the pipe 101 near the end of the sealing column 320. A control button 302 and a control terminal 303 are respectively installed on the outside of the housing 301 to facilitate real-time flow control by the operator. Ear plates 305 are fixedly installed on both sides of the motor 304. The motor 304 and ear plates 305 are fixed to the housing 301 with bolts to ensure stable motor operation. When the operator presses the control button 302, the motor 304 drives the sealing column 320 to move, thereby adjusting the size of the plugging hole 104 and achieving precise control of the refrigerant flow. This design ensures the sealing performance of the device while improving the automation level of operation and the reliability of the system.

[0029] Example 2: A battery compartment 306 is provided on the top of the motor 304. A cover plate 307 is rotatably provided on the top of the battery compartment 306. A handle 308 is fixedly provided on one side of the top of the cover plate 307. The rotating drum 311 is rotatably set with the box body 301 through the bearing seat 312 to achieve smooth rotation. The support seat 315, the fixed seat 316 and the connecting seat 317 are fixedly set with bolts to enhance the stability of the device. The guide rod 319 is fixedly set inside the box body 301 to ensure the accuracy of the movement of the sealing column 320 inside the pipe 101. The sealing column 320 is movably set inside the pipe 101 in the refrigerant pipe assembly 1 and is located directly above the sealing door 103. The cone head of the sealing column 320 is adapted to the plugging hole 104. Driven by the motor, the sealing column 320 can accurately seal the plugging hole 104, thereby controlling the refrigerant flow. This design improves the automation level and ease of operation of the device.

[0030] Working Principle: The device controls the refrigerant flow rate through the pipe 101 and the sealing valve 103 in the refrigerant pipe assembly 1. The sealing valve 103 has a sealing hole 104 inside. By adjusting the size of the sealing hole 104, the refrigerant flow rate can be precisely controlled. The flow control assembly 3 is installed on the mounting bracket 102 at the top of the pipe 101. It includes components such as a housing 301, a motor 304, a pinion 309, a large gear 310, a rotating drum 311, a screw 313, a threaded cylinder 314, a support base 315, a connecting base 317, a fixing base 316, a guide base 318, and a sealing column 320. When the operator needs to adjust the refrigerant flow rate, by pressing the control button 302, the motor 304 starts and drives the pinion 309, which in turn drives the large gear 310 and the rotating drum 311 to rotate. The screw 313 at the bottom of the rotating drum 311 moves the support base 315 up and down through the threaded cylinder 314. The connecting seat 317 and the fixed seat 316 move accordingly, and the guide seat 318 slides on the guide rod 319, thereby driving the sealing column 320 to move. When the sealing column 320 moves away from the sealing door 103, the plugging hole 104 opens, and the refrigerant flow increases. When the sealing column 320 is inserted into the plugging hole 104, it can block or reduce the refrigerant flow. The sealing ring 2 ensures the sealing of the inside of the pipe 101, while the fixing method of the ear plate 305 and the bolts ensures the stable operation of the motor 304. The design of the battery compartment 306 and the cover plate 307 facilitates battery replacement, while the bearing seat 312 ensures the smooth rotation of the drum 311. The fixing of the guide rod 319 and the movable setting of the sealing column 320 enable the sealing column 320 to accurately seal the plugging hole 104, thereby achieving precise control of the refrigerant flow, improving the automation level of the device, and enhancing the convenience of operation and the reliability of the system.
