[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Reference Figure 1-3 A control device for switching between different media during a production process includes a reaction vessel 1, which is externally connected to a container jacket. It also includes: an inlet pipe 101 and an outlet pipe 102, respectively connected to the inlet and outlet ends of the container jacket; a hot water container 2, connected to a hot water outlet 201 and a hot water inlet 202, which are respectively connected to the inlet pipe 101 and the outlet pipe 102; and a cold water container 3, connected to... The system is equipped with a cold water outlet 301 and a cold water inlet 302, which are connected to the liquid inlet pipe 101 and the liquid outlet pipe 102, respectively. A nitrogen tank 4 is connected to a nitrogen outlet 401, which is connected to the liquid inlet pipe 101. Valves are installed in the hot water outlet 201, hot water inlet 202, cold water outlet 301, cold water inlet 302, and nitrogen outlet 401. A pressure relief pipe 501 is connected to the liquid inlet pipe 101, and a valve is installed in the pressure relief pipe 501.

[0029] In practical use, if hot water is used first, open the hot water outlet 201 and hot water inlet 202 valves. At this time, the hot water will enter the container jacket of the reaction vessel 1 to heat the reaction vessel 1. The hot water will circulate. When cold water is needed for cooling later, close the hot water outlet 201 and start the nitrogen outlet 401. The nitrogen will enter the container jacket through the liquid inlet pipe 101, and then the hot water will flow back into the hot water container 2 through the hot water inlet 202. Then open the pressure relief pipe 501 to release the excess gas.

[0030] At this point, there is basically no cold water left in the pipes, and you can then use hot water to heat it normally.

[0031] This process can be quickly performed by a single person, effectively saving time and pipe materials.

[0032] Example 2:

[0033] Reference Figure 1-4A control device for switching between different media during the production process is basically the same as in Embodiment 1, but with the following additional features: a filter tank 6 is connected to the inlet pipe 101, a filter screen 602 is installed inside the filter tank 6, a spring element 601 is installed inside the filter tank 6, the filter screen 602 is connected to the spring element 601, a ring body 603 is fixedly connected to the filter screen 602, multiple sets of protrusions 606 are installed inside the filter tank 6, a striking block 604 is slidably connected inside the ring body 603, and a second spring element 605 is connected inside the ring body 603, the second spring element 605 is connected to the striking block 604, an auxiliary pipe 402 is connected to the nitrogen outlet 401, a valve is installed inside the auxiliary pipe 402, valves are installed at both ends of the filter tank 6, and the outlet end of the auxiliary pipe 402 is located at the outlet end of the filter tank 6 and upstream of the valve at the outlet end of the filter tank 6, and a storage tank 502 is installed at the outlet end of the pressure relief pipe 501.

[0034] The filter tank 6 filters the water entering the container jacket, reducing the entry of impurities. After a period of use, impurities accumulate in the filter screen 602. When switching between hot and cold water, such as from cold to hot water, nitrogen remains in the pipeline after the switch is completed. Before opening the pressure relief pipe 501, simply open the valve of the auxiliary pipe 402 and close the valve of the inlet pipe 101 near the reaction vessel 1 and the valve of the nitrogen outlet 401. The nitrogen will then directly enter the outlet of the filter tank 6 through the auxiliary pipe 402. If the valve of the pressure relief pipe 501 is opened at this time, the filter screen 602 will move under the impact of the gas. At the same time, the impurities remaining on the filter screen 602 will be discharged through the pressure relief pipe 501. During the movement, the striking block 604 will contact the protrusion 606, generating vibration, which will loosen the impurities and discharge them through the pressure relief pipe 501.

[0035] After use, close the pressure relief pipe 501 and auxiliary pipe 402, and then refill with hot water.

[0036] This invention aims to save materials during the initial installation and improve efficiency and ease of operation when switching between multiple media in the same container. At the same time, the filter tank 6 can filter the incoming water, which is convenient for long-term use.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
