Abstract
Description
Technical Field
[0001] This utility model relates to the field of valve accessory technology, and more specifically, to a cooling device for a positioning module of a heat medium regulating valve. Background Technology
[0002] High-temperature heat transfer media are required in textile production. These media are transported via dedicated pipelines. A heat transfer media regulating valve is a specialized valve installed on these pipelines. The core of this valve is the I / P (Integrated Power Supply) module, which controls the valve's opening and closing range. However, in actual production, it has been observed that these regulating valves are prone to malfunctioning in hot summer conditions. This is because both the heat transfer media pipelines and the regulating valve are installed in the confined space of a workshop. The pipelines themselves radiate heat (the heat transfer media inside reaches temperatures close to 300 degrees Celsius), and combined with the ambient temperature in summer, the I / P module of the regulating valve can reach temperatures exceeding 60 degrees Celsius. When the I / P module reaches temperatures above 55 degrees Celsius, it begins to malfunction, leading to valve malfunction and disrupting normal production. Therefore, companies need to design cooling structures around the I / P module's installation location to ensure the normal operation of the regulating valve. Utility Model Content
[0003] The purpose of this invention is to address the needs of the prior art by providing a cooling device for a positioning module of a heat transfer medium regulating valve. This invention designs a module mounting box to install the I / P conversion module. The module mounting box is equipped with heat exchange pipelines that are connected to a cooling system. Under stable and rising environmental conditions, the I / P conversion module can be cooled by air-cooled heat exchange to ensure the normal operation of the heat transfer medium regulating valve.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A cooling device for a heat transfer medium regulating valve positioning module includes a module mounting box and a cooling system. The module mounting box has a cavity, and a mounting plate is fixedly installed inside the cavity. The mounting plate is used to install an I / P conversion module. The cooling system includes a refrigerant inlet pipe, a heat exchange pipeline, and a refrigerant outlet pipe. The refrigerant inlet pipe and the refrigerant outlet pipe are installed on the outside of the module mounting box. The heat exchange pipeline is installed through the cavity, and its two ends extend to connect to the refrigerant inlet pipe and the refrigerant outlet pipe, respectively.
[0006] Furthermore, the heat exchange pipeline includes a first heat exchange tube, a second heat exchange tube, and a third heat exchange tube. The first heat exchange tube, the second heat exchange tube, and the third heat exchange tube are vertically installed in the cavity. The first heat exchange tube and the second heat exchange tube are symmetrically installed on the left and right sides of the plate base, and the third heat exchange tube is installed at the rear of the plate base.
[0007] Furthermore, both ends of the first, second, and third heat exchange tubes extend out of the module mounting box. The refrigerant input pipe is vertically and fixedly installed on the side of the module mounting box. The lower ends of the first, second, and third heat exchange tubes extend and are connected to the refrigerant input pipe. The refrigerant exhaust pipe is horizontally and fixedly installed above the module mounting box. The upper ends of the first, second, and third heat exchange tubes extend and are connected to the refrigerant exhaust pipe.
[0008] Furthermore, a temperature sensor is installed on the side of the module mounting box, and the probe of the temperature sensor is located inside the cavity. A temperature control valve is installed on the connecting pipes of the first heat exchange tube, the second heat exchange tube, and the third heat exchange tube to the refrigerant input pipe. The opening temperature settings of the three temperature control valves are different.
[0009] Furthermore, a one-way valve is installed on each of the connecting pipes of the first heat exchange tube, the second heat exchange tube, and the third heat exchange tube to the refrigerant discharge pipe. The one-way valve controls the refrigerant to move only from the module installation box toward the refrigerant discharge pipe.
[0010] Furthermore, the cooling system uses air at - degrees Celsius as the cooling medium.
[0011] Furthermore, the three temperature control valves are initially closed, and their opening temperatures are set to 10 degrees Celsius, 10 degrees Celsius, and 10 degrees Celsius, respectively.
[0012] Furthermore, the housing of the module installation box is made of heat-insulating material, and the first heat exchange tube, the second heat exchange tube, and the third heat exchange tube are made of materials with good heat exchange properties.
[0013] Furthermore, the module mounting box is equipped with a movable door, a cable routing port is provided at the bottom of the module mounting box, and a flange seat is installed on the back of the module mounting box.
[0014] The beneficial effects of this utility model are:
[0015] 1. This utility model is designed with a modular installation box for installing I / P conversion modules. The modular installation box is designed with heat exchange pipelines, which are connected to a cooling system. When the ambient temperature rises steadily, the air-cooled heat exchange mode can be activated by a temperature sensor to cool the I / P conversion module, thereby ensuring the normal operation of the heat medium regulating valve and extending the service life of the valve positioner's I / P conversion module.
[0016] 2. The heat exchange pipeline design of this utility model has three heat exchange pipelines, which can be gradually opened according to the ambient temperature rise, thus ensuring operation and saving energy. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figure 1 As shown, a heat medium regulating valve 4 is installed on the heat medium pipeline 3. A heat medium with a temperature of nearly 300 degrees Celsius flows inside the heat medium pipeline 3. The heat medium pipeline 3 itself will radiate and dissipate a certain amount of heat. Combined with the temperature of the indoor environment in summer, the I / P conversion module 5 on the heat medium regulating valve 3 will reach a temperature of over 60 degrees Celsius. When the temperature of the I / P conversion module 5 is above 55 degrees Celsius, it will malfunction. This will lead to the loss of control of the heat medium regulating valve 4 and affect normal production operations. The solution of this utility model is to design and solve the cooling and temperature control problem of the I / P conversion module 5 so that the I / P conversion module 5 can operate normally.
[0023] like Figures 1-3The cooling device for a heat transfer medium regulating valve positioning module includes a module mounting box 1 and a cooling system 2. The module mounting box 1 has a cavity 11, and a mounting plate 12 is fixedly installed inside the cavity 11. The mounting plate 12 is used to install an I / P conversion module 5. This invention uses heat-insulating material to make the box 1, which protects the I / P conversion module 5 and effectively suppresses the temperature rise within the box. Simultaneously, the cooling system 2 is designed to cool the interior of the box, preventing the I / P conversion module 5 from overheating. The cooling system 2 includes a refrigerant inlet pipe 21, a heat exchange pipeline 22, and a refrigerant outlet pipe 23. The refrigerant inlet pipe 21 and the refrigerant outlet pipe 23 are installed on the outside of the module mounting box 1. The heat exchange pipeline 22 is installed through the cavity 11. The two ends of the heat exchange pipeline 22 extend and connect to the refrigerant inlet pipe 21 and the refrigerant outlet pipe 23, respectively. The refrigerant flows along the direction of the refrigerant inlet pipe 21, the heat exchange pipeline 22, and the refrigerant outlet pipe 23. Inside the cavity 11, the heat exchange pipeline 22 can bring heat exchange and cooling effect to the inside of the cavity 11 to prevent the temperature inside the cavity 11 from rising.
[0024] like Figure 2 As shown, the heat exchange pipeline 22 of this utility model includes a first heat exchange pipe 221, a second heat exchange pipe 222, and a third heat exchange pipe 223. The first heat exchange pipe 221, the second heat exchange pipe 222, and the third heat exchange pipe 223 are vertically installed in the cavity 11. The first heat exchange pipe 221 and the second heat exchange pipe 222 are symmetrically installed on the left and right sides of the plate base 12, and the third heat exchange pipe 223 is installed at the rear of the plate base 12. The three heat exchange pipes are arranged circumferentially around the I / P conversion module 5. Once any one heat exchange pipe is activated, it can quickly form a cooling effect on the nearby I / P conversion module 5. The simultaneous activation of the three heat exchange pipes can amplify the cooling effect. In actual use, it has been found that even in the hottest summer weather, the temperature inside the cavity 11 can be controlled below 50 degrees Celsius when the three heat exchange pipes are activated simultaneously, ensuring the normal operation of the I / P conversion module 5.
[0025] like Figure 2As shown, both ends of the first heat exchange tube 221, the second heat exchange tube 222, and the third heat exchange tube 223 extend out of the module mounting box 1. The refrigerant inlet pipe 21 is vertically fixedly installed on the side of the module mounting box 1. The lower ends of the first heat exchange tube 221, the second heat exchange tube 222, and the third heat exchange tube 223 extend and are connected to the refrigerant inlet pipe 21 to form three refrigerant inlet branches. The refrigerant outlet pipe 23 is horizontally fixedly installed above the module mounting box 1. The first heat exchange tube 221, the second heat exchange tube 222, and the third heat exchange tube 223... The upper ends of heat exchange tubes 221 and 222 and the third heat exchange tube 223 are extended and connected to the refrigerant discharge pipe 23 to form three refrigerant discharge branches. A one-way valve 25 is installed on the connecting pipes of the first heat exchange tube 221, the second heat exchange tube 222 and the third heat exchange tube 223 to the refrigerant discharge pipe 23. The one-way valve 25 can only be opened in one direction. In this utility model, the one-way valve 25 is designed to control the refrigerant to move only from the module installation box 1 toward the refrigerant discharge pipe 23, so as to prevent the refrigerant from flowing into other branches when it is discharged.
[0026] To reduce the energy consumption of cooling system 2, the three branch pipes—first heat exchanger 221, second heat exchanger 222, and third heat exchanger 223—need to operate at a constant temperature, and they need to be set to open according to different internal temperatures of cavity 11, such as... Figure 2 As shown, this utility model has a temperature sensor 13 installed on the side of the module mounting box 1. The probe of the temperature sensor 13 is located inside the cavity 11. The temperature sensor 13 monitors the temperature change inside the cavity 11 in real time and outputs temperature data to the outside. A temperature control valve 24 is installed on the connecting pipes of the first heat exchange tube 221, the second heat exchange tube 222, and the third heat exchange tube 223 to the refrigerant input pipe 21. The opening temperatures of the three temperature control valves 24 are different. The three temperature control valves 24 are initially closed. According to the temperature monitoring of the temperature sensor 13... The obtained temperature data is used to control the opening of three temperature control valves 24 as needed. The opening temperatures of the three temperature control valves 24 are set to 40 degrees Celsius, 44 degrees Celsius and 48 degrees Celsius respectively. That is, when the internal temperature of the cavity 11 reaches 40 degrees Celsius, one heat exchange tube is opened; when it reaches 44 degrees Celsius, two heat exchange tubes are opened; and when it reaches 48 degrees Celsius, all three heat exchange tubes are opened. In actual application, it has been found that opening the first heat exchange tube 221, the second heat exchange tube 222 and the third heat exchange tube 223 at the same time can meet the requirement of temperature control below 50 degrees Celsius.
[0027] Since the I / P conversion module 5 is an electronic component, considering potential accidents such as pipe leaks, the cooling system 2 preferably uses air at 20-26 degrees Celsius as the cooling medium. The cold air can meet the heat exchange and cooling requirements, and even if a leak occurs, it will not have a significant impact on the I / P conversion module 5 and the workshop environment. This invention can also directly ventilate the module installation box 1 to cool the I / P conversion module 5, but this requires high cleanliness and humidity of the cold air, since the I / P conversion module 5 is an electronic component. Therefore, this invention adopts a pipe heat exchange mode design, with cold air passing through the first heat exchange pipe 221, the second heat exchange pipe 222, and the third heat exchange pipe 223 for heat exchange and cooling. In this way, the cold air can meet the cooling requirements without affecting the I / P conversion module 5, and the cleanliness and humidity of the air are not too demanding, so natural wind can be used.
[0028] In this invention, the first heat exchange tube 221, the second heat exchange tube 222 and the third heat exchange tube 223 should be made of materials with good heat exchange performance, such as copper and other metal materials, so as to ensure the quality of heat exchange and cooling.
[0029] like Figure 3 As shown, the module mounting box 1 is equipped with a movable door 14. The movable door 14 is designed to facilitate the installation and maintenance of the I / P conversion module 5. The bottom of the module mounting box 1 is provided with a wiring port 15, which is used to meet the wiring requirements of the I / P conversion module 5 and the heat medium regulating valve 4. A flange seat 16 is installed on the back of the module mounting box 1, which allows the module mounting box 1 to be fixedly installed on the side of the heat medium regulating valve 4.
