[0039] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme of the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0040] The valve with anti-icing function and the cut tobacco expansion line provided by the utility model embodiment will be described in detail below in combination with specific embodiments and application scenarios. Figures 1 to 3

[0041] In the first aspect, in some embodiments, as shown in Figure 1 and Figure 2 , the embodiment provides a valve with anti-icing function, comprising a valve body 11, a heat conduction assembly 12, a heating assembly 13 and a heat insulation assembly 14.

[0042] The heat conduction assembly 12 is connected with the valve body 11, the heating assembly 13 is arranged on the valve body 11, the heating assembly 13 is connected with the heat conduction assembly 12, and the heat insulation assembly 14 forms a containing cavity, which covers the valve body 11, the heat conduction assembly 12 and the heating assembly 13 in the heat insulation assembly 14.

[0043] The heating assembly 13 is used for heating the valve body 11.

[0044] It can be understood that on the cut tobacco expansion line, a valve 1 for opening and closing the pipeline for conveying high-pressure carbon dioxide liquid to the process tank 4 is arranged on the pipeline.

[0045] Specifically, the valve body 11 can be a ball valve.

[0046] When the temperature of the pipeline is relatively low and the valve body 11 is frozen to cause the valve body 11 to be unable to adjust the opening and closing state, the heating assembly 13 is used for heating the valve body 11, so that the valve body 11 is not frozen.

[0047] Specifically, the heating assembly 13 can be a heating pipe or a heater.

[0048] The heat conduction assembly 12 is used for uniformly transmitting the heat generated by the heating assembly 13 to each part of the valve body 11, so as to avoid different thermal stresses of each part of the valve body 11 due to the non-uniform temperature and ensure that the valve body 11 can uniformly and gradually increase the temperature.

[0049] Specifically, the heat conduction assembly 12 can be a heat conduction sheet or a heat conduction strip.

[0050] ​In order to prevent the damage to external equipment or the scalding of the operator when the valve body 11 is too high in temperature, a heat insulation assembly 14 is arranged outside the valve body 11, which can not only insulate the heat of the valve body 11, but also keep the valve body 11 warm.

[0051] The valve 1 with the anti-icing function provided by the utility model can melt the frozen water in the valve body 11 at low temperature, realize the thawing function, avoid the influence on the normal opening and closing of the valve body 11, and make the heat generated by the heating assembly 13 uniformly transmitted to each part of the valve body 11 by using the heat conduction assembly 12, and the valve body 11, the heat conduction assembly 12 and the heating assembly 13 are arranged in the heat insulation assembly 14, which can not only avoid the damage to external equipment and the scalding of the operator, but also keep the valve body 11 warm and save energy.

[0052] In some embodiments, as shown in Figure 1 The heating assembly 13 of the embodiment comprises a heating wire.

[0053] The heating wire is provided in multiple pieces, and the multiple pieces of heating wire are arranged at intervals and wound on the outer wall of the valve body 11.

[0054] It can be understood that for the valve on the tobacco expansion line, the valve is large in volume and irregular in shape, and the shape of the heating wire can be changed according to the shape of the wound object, so that the heating wire can be attached to the outer wall of the valve body 11 and matched with the shape of the valve body 11.

[0055] The multiple pieces of heating wire are arranged at intervals on the outer wall of the valve body 11, which can uniformly heat the outer wall of the valve body 11, ensure the consistency of the temperature rise of the valve body 11, and avoid the thermal stress caused by the temperature difference in the valve body 11.

[0056] The heating wire and the valve body 11 can be connected through a buckle structure or a structure of a groove and a protrusion.

[0057] In some embodiments, as shown in Figure 1 The valve 1 of the embodiment further comprises a magnetic attraction assembly 15.

[0058] The magnetic attraction assembly 15 comprises a first magnetic member and a second magnetic member, and the first magnetic member and the second magnetic member can be attracted to each other.

[0059] The first magnetic member is arranged on the valve body 11, and the second magnetic member is arranged on the heating wire.

[0060] It can be understood that, based on the mutual attraction between the first magnetic member and the second magnetic member, the valve body 11 and the heating wire can be firmly adsorbed and connected, and when it is necessary to disassemble and replace or repair the heating wire, the operation of moving the heating wire away from the valve body 11 is also very convenient.

[0061] The embodiment sets the magnetic attraction assembly 15 on the valve 1, so that the heating wire can be fixed by the magnetic attraction assembly 15, and the heating wire is tightly and firmly adsorbed on the valve body 11, which ensures the stability and reliability of the heating wire and is easy to disassemble the heating wire from the valve body 11.

[0062] In some embodiments, as shown in Figure 1 The heat conduction assembly 12 of the embodiment includes a heat conduction block.

[0063] The heat conduction block is provided with a plurality of heat conduction blocks, one end of the plurality of heat conduction blocks is connected with the valve body 11, and the other end is connected with the heating assembly 13.

[0064] The plurality of heat conduction blocks are evenly arranged along the outer wall of the valve body 11.

[0065] It can be understood that, since the heating wire cannot cover the entire outer wall of the valve body 11, there is an area on the outer wall of the valve body 11 that is not directly heated, and the heat conduction block can quickly conduct the heat generated by the heating wire to the valve body 11, ensuring uniform distribution of the heat field on the valve body 11. The uniform arrangement of the plurality of heat conduction blocks along the outer wall of the valve body 11 ensures that the heat conduction points of the valve body 11 are evenly distributed and the number is large, ensuring that heat is conducted in as small an area as possible on the outer wall of the valve body 11. The outer wall of the valve body 11 is heated in all directions and in three dimensions, improving the efficiency of heating the valve body 11 and ensuring better thawing effect of the valve body 11.

[0066] In some embodiments, as shown in Figure 1 The heat insulation assembly 14 of the embodiment includes an inner lining 141 and a heat insulation shell 142.

[0067] The heat insulation shell 142 is provided on the valve body 11, and the heat insulation shell 142 is detachably connected with the valve body 11; the inner lining 141 is applied to the inner wall of the heat insulation shell 142.

[0068] It can be understood that the heat insulation shell 142 and the valve body 11 can be connected by fasteners or clamping members, and the detachable connection of the heat insulation shell 142 and the valve body 11 facilitates the disassembly of the heat insulation shell 142 from the valve body 11 for maintenance of the valve body 11.

[0069] The inner lining 141 is made of high-temperature-resistant thermal insulation cotton, which can keep the temperature of the valve body 11 and prevent heat loss to the external environment. At the same time, it can also prevent the temperature of the valve body 11 from being directly transmitted to external equipment or operators. The heat-insulating shell 142 is made of fireproof, waterproof, and corrosion-resistant thermal insulation shell, which can protect the internal valve body 11, play a physical isolation role, and ensure the aesthetics of the valve body 11.

[0070] In some embodiments, as shown in Figure 3 The valve 1 of the present embodiment further comprises a temperature sensor 16 and a control module 17.

[0071] The temperature sensor 16 is arranged on the pipeline upstream of the valve body 11. The temperature sensor 16 is used to detect the temperature information of the pipeline. The temperature sensor 16 and the control module 17 are electrically connected. The control module 17 and the heating wire are electrically connected.

[0072] The control module 17 is used to control the working state of the heating wire according to the temperature information fed back by the temperature sensor 16.

[0073] It can be understood that since the temperature of the pipeline upstream of the valve body 11 is similar to that of the valve body 11, the temperature of the pipeline can be used to represent the temperature inside the valve body 11.

[0074] The working state of the heating wire includes the start and stop of heating, and the adjustment of the power of the heating wire. When the temperature sensor 16 detects that the temperature is lower than 0℃, the control module 17 controls the heating wire to start heating. When the temperature sensor 16 detects that the temperature is higher than 5℃, the control module 17 controls the heating wire to stop heating. When the temperature detected by the temperature sensor 16 is lower than 0℃ for a long time, the control module 17 controls the heating wire to work at a higher power. When the temperature detected by the temperature sensor 16 is lower than 5℃ for a short time, the control module 17 controls the heating wire to work at a lower power.

[0075] The control module 17 of the present embodiment can be any one of the commonly known industrial computers, PLC controllers or single-chip microcomputers in the art. The temperature sensor 16 can be a thermal resistor.

[0076] The present embodiment sets the temperature sensor 16 and the control module 17, so that based on the temperature information of the valve body 11 collected by the temperature sensor 16, the control module 17 can control the start and stop of the heating wire and the adjustment of the power, so that the temperature adjustment of the valve body 11 can be automatically controlled without manual intervention, and convenient control and adjustment of the temperature of the valve body 11 are realized.

[0077] In some embodiments, as shown in Figure 1 and Figure 3 The valve 1 of the present embodiment further comprises a position detection sensor 18 and an electric actuator 19.

[0078] The position detection sensor 18 is used to detect the opening and closing information of the valve body 11, the position detection sensor 18 is electrically connected with the control module 17, and the control module 17 is electrically connected with the electric actuator 19.

[0079] The control module 17 is used to control the working state of the electric actuator 19 according to the opening and closing information of the valve body 11 fed back by the position detection sensor 18.

[0080] It can be understood that the position of the valve stem is different at different positions of the valve body 11 in the opening and closing states, the position detection sensor 18 can detect the different positions of the valve stem in the horizontal plane, so as to determine the opening and closing state of the valve body 11, and the electric actuator 19 can control the opening and closing state of the valve body 11, so that the position detection sensor 18 detects that the valve body 11 is in the opening position or the closing position, and the electric actuator 19 controls the opening and closing of the valve body 11, so as to automatically know the initial state and the state after control of the valve 1, and the automatic control of the opening and closing of the valve body 11 is realized, and the efficiency of the opening and closing of the valve body 11 is improved.

[0081] The position detection sensor 18 can be an optical sensor.

[0082] In some embodiments, as shown in Figure 3 The valve 1 of the embodiment further comprises an alarm module 20, the control module 17 is electrically connected with the alarm module 20, and the control module 17 controls the working state of the alarm module 20 according to the temperature information fed back by the temperature sensor 16.

[0083] It can be understood that the temperature sensor 16 feeds back the temperature information to the control module 17, and when the temperature of the valve body 11 is lower than 0℃, the control module 17 controls the alarm module 20 to alarm, so that the operator knows that the valve body 11 has the possibility of freezing.

[0084] The alarm module 20 can be a buzzer, which emits a sound alarm when the temperature of the valve body 11 is lower than 0℃, or the alarm module 20 can be an audible and light alarm, which emits a sound alarm and a light alarm when the temperature of the valve body 11 is lower than 0℃.

[0085] In some embodiments, as shown in Figure 3 The valve 1 of the embodiment further comprises a wireless communication module 21, the control module 17 is connected with the wireless communication module 21, and the control module 17 is used to control the wireless communication module 21 to send the temperature information of the valve body 11 to the upper computer 22.

[0086] It can be understood that the wireless communication module 21 includes at least one of a Wi-Fi module, a 4G module, and a 5G module. The control module 17 can establish a communication connection with the host computer 22 through the wireless communication module 21.

[0087] The operator can remotely connect the host computer 22 to the control module 17 through the Wi-Fi module or the 4G / 5G mobile network, so as to receive the detection information of the valve body 11 uploaded by the control module 17 through the host computer 22, store the temperature information of the valve body 11 in different time periods in a large amount, facilitate the operator to call and compare data, and enable the operator to control the control module 17 using the host computer 22 to remotely control the start and stop of the heating assembly 13 and the heating power.

[0088] In some embodiments, the valve 1 of the present embodiment further comprises a control box.

[0089] The control box is cuboid, and the control box is arranged opposite to the valve body 11. The control module 17, the alarm module 20, and the wireless communication module 21 are arranged in the control box.

[0090] It can be understood that, in order to ensure the normal use of the control module 17, the alarm module 20, and the wireless communication module 21, the control box can physically protect the control module 17, the alarm module 20, and the wireless communication module 21, and make the on-site arrangement have aesthetic appearance.
