[0002] With the rapid development of China's economy, China's total energy consumption is increasing, and China has become the world's largest energy consumer. Among them, industrial energy consumption accounts for more than 70% of China's total energy consumption, and at least 50% of industrial energy consumption is converted into industrial waste heat with different carriers and different temperatures. However, the recovery and utilization rate of industrial waste heat in China is low, and only 30% of the waste heat can be recovered and utilized. Among them, low-temperature waste heat has small recovery temperature difference, large heat exchange equipment, complex technology, and long investment recovery period, which leads to the neglect of low-temperature industrial waste heat by enterprises.

[0003] At present, hydrogen energy is applied in more and more scenes due to its cleanliness, renewability and high energy density characteristics, but it is still limited by its high transportation and storage cost. Especially in the transportation process, there are a large number of electromagnetic valves, and the annual power consumption cannot be ignored. The temperature difference between the ultra-low temperature of liquid hydrogen and room temperature has great potential in energy recovery and utilization, which provides a solution to the above problems. Therefore, under the background of the "double carbon" goal, it is of great practical significance to use the temperature difference between liquid hydrogen and room temperature to generate electricity to power the electromagnetic valve.

[0004] Therefore, an electromagnetic valve device using temperature difference power generation is provided. UTILITY MODEL CONTENTS

[0029] This embodiment provides a solenoid valve device that utilizes thermoelectric power generation, as shown in the attached instruction manual. Figures 1-5 As shown, it includes an outer casing 1, a thermoelectric element 4, and a solenoid valve body 5, wherein:

[0030] The solenoid valve body 5 is a solenoid valve body. The outer shell 1 in this embodiment is installed on the solenoid valve body 5. In this embodiment, the solenoid valve body 5 is a two-way pipe. In order to ensure the safe and stable operation of the solenoid valve body 5, it can be connected to the power grid and power the solenoid valve body 5 through the power grid when necessary. At the same time, the end of the outer shell 1 away from the solenoid valve body 5 is designed as a flange to facilitate subsequent pipe connection. The flange and the subsequent pipe are fastened with rubber gaskets to prevent leakage.

[0031] The outer casing 1 is fitted onto the end of the solenoid valve body 5. The outer casing 1 is provided with an external thread 9 near the end port of the solenoid valve body 5, and a corresponding internal thread is also provided at the end port of the solenoid valve body 5. The assembly is completed by installing it at the end port of 05 through a threaded assembly method.

[0032] The valve body pipe 6 is arranged through the inner side of the outer shell 1. In the embodiment, the outer side wall of the valve body pipe 6 is arranged in a regular hexagon. The low-temperature medium flowing in the valve body pipe 6 forms a low-temperature cavity. The environment temperature cavity is formed between the outer shell 1 and the valve body pipe 6. Specifically, the valve body pipe 6 comprises a pipe inner wall 61 and a pipe outer wall 62, which facilitate the medium flow. The low-temperature medium flowing in the pipe inner wall 61 forms a low-temperature cavity. The environment temperature cavity is formed by the environment temperature air duct on the outer side of the pipe outer wall 62.

[0033] The number of the thermoelectric sheets 4 is six, which are arranged in a circular array around the valve body pipe 6. The six thermoelectric sheets 4 are wrapped on the outer wall surface of the valve body pipe 6 by the heat-conducting glue. One side of the thermoelectric sheet 4 is located in the environment temperature cavity to form an environment temperature side 41. The other side of the thermoelectric sheet 4 is adhered to the outer side wall of the valve body pipe 6 by the heat-conducting glue to form a low-temperature side 42. The thickness of the heat-conducting glue should be as thin as possible under the premise of ensuring the fastening, so that the temperature of the low-temperature side 42 is consistent with the temperature of the working medium as much as possible. The thermoelectric sheet 4 converts the temperature difference between the environment temperature side 41 and the low-temperature side 42 into voltage output. The temperature of the low-temperature side 42 is approximately equal to the temperature of the medium flowing in the pipe inner wall 61. Since the outer side of the pipe outer wall 62 is the environment temperature air duct, the temperature of the environment temperature side 41 is approximately equal to the environment temperature. Thus, the temperature difference is formed on both sides of the thermoelectric sheet 4. The thermoelectric sheet 4 converts the temperature difference into voltage output, thereby realizing power generation.

[0034] Specifically, the thickness of the valve body pipe 6 should be as thin as possible under the premise of meeting the strength, so as to reduce the pipe wall thermal resistance, so that the temperature of the working medium flowing in the pipe inner wall 61 is approximately equal to the temperature of the low-temperature side 42. The medium flowing in the pipe inner wall 61 is liquid hydrogen, liquefied gas or other ultra-low temperature working medium, and the temperature is usually between-200℃ and-80℃. Therefore, the pipe inner wall 61 presents low temperature, and the low-temperature side 42 also presents low temperature.

The thermoelectric sheet 4, the electronic control box 10 and the storage battery 11 are electrically connected through a line. The transformer, the electromagnetic coil and the control module are installed in the electronic control box 10. The electromagnetic coil controls the opening and closing of the electromagnetic valve body 5, which is equivalent to a switch. This is prior art, so it will not be described in detail here. The temperature sensor is arranged on the surface of the pipe outer wall 62 and the outer shell 1. This is prior art. The control module in the electronic control box 10 is connected with the thermoelectric sheet 4, the storage battery 11, the transformer and the electromagnetic coil respectively. The control module can calculate the expected power generation voltage, current and power according to the temperature difference. After comparing with the actual required voltage, current and power, the connection mode of the thermoelectric sheet 4, whether to step up, whether to output to the storage battery or the electromagnetic coil is adjusted.

[0036] Please refer to the attached drawings of the specification Figure 2Further to the power generation of the thermoelectric sheet 4 in the embodiment, the circuit connects the thermoelectric sheet 4 with the electromagnetic valve body 5, the electric control box 10 and the battery 11 together, when the low-temperature working medium enters the inner wall 61 of the pipeline, the temperature sensor at the outer wall 62 detects the temperature, the temperature sensor at the outer shell 1 detects the ambient temperature, and the data is transmitted to the control module to calculate the expected power generation voltage and power, and then select whether to perform voltage conversion and whether the battery needs to be charged or discharged, and then control the opening and closing of each switch.

[0037] If the thermoelectric sheet 4 is insufficient to directly supply power to the electromagnetic coil, the circuit switch between the thermoelectric sheet 4 and the battery 11 is opened, and the battery 11 stores energy;

[0038] If the thermoelectric sheet 4 is insufficient to directly supply power to the electromagnetic coil, the circuit switch between the thermoelectric sheet 4 and the battery 11 is opened, and the battery 11 stores energy;

[0039] When sending the opening and closing instructions to the electromagnetic coil, it is determined whether the battery capacity is sufficient, if not, the connection switch between the power grid and the battery and the electromagnetic valve is opened at the same time, to ensure the safety and stability of the electromagnetic valve;

[0041] Air enters the inside of the outer shell 1 through the upper air vents 3, and the air flows from top to bottom, and then is discharged from the lower air vents 8, forming an air duct, so that the air inside the ambient temperature chamber exchanges with the outside air, keeping the temperature of the ambient temperature chamber consistent with the air temperature.

[0042] Please refer to the drawings in the specification Figures 3-5 To achieve waterproof and dustproof, the internal structure of the outer shell 1 is further described as follows:

[0044] And, the middle part of the lower vent 8 is provided with a lower arc-shaped baffle 7, the lower arc-shaped baffle 7 is smoothly curved from the middle part to both sides, thereby forming an arch structure;

[0045] When the air flows along the air duct, the water and dust mixed in the air enter the ambient temperature cavity inside the outer shell 1 through the upper vent 3, at this time, the entering water and dust are guided by the upper arc-shaped baffle 2 and move along the inner arc surface of the upper arc-shaped baffle 2, and flow to the position of the lower vent 8 under the action of gravity, thereby being discharged;

[0046] And the arch-shaped lower arc-shaped baffle 7 can hinder the water and dust from entering from the direction of the lower vent 8, when the water and dust enter the outer shell 1 from the lower vent 8, the water and dust are hindered by the lower arc-shaped baffle 7 of the arch structure at the entrance and stay on the inner arc surface of the lower arc-shaped baffle 7, and then move out of the lower vent 8 under the action of gravity.
