[0017] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0018] Please see Figs. 1-4 A training device for the construction of chemical process pipelines includes a water storage tank 2 and a circulation pipeline. The circulation pipeline is composed of multiple flanged pipe sections connected together. The circulation pipeline is divided into a water supply pipeline and a return water pipeline. The water supply pipeline has two main water supply pipe sections, upstream and downstream, which are connected by two parallel water supply branch pipes. A first valve 3-1 is installed on the upstream water supply pipe section, a second valve 3-2 is installed on any one of the water supply branch pipes, and a third valve 3-3 and a fourth valve 3-4 are installed on the other water supply branch pipe. A first pressure gauge 4-1 is installed at the end of the upstream water supply pipe section, and a second pressure gauge 4-2 is installed on the downstream water supply pipe section.

[0019] The return water pipeline has two parallel upstream return water branch pipes and two parallel downstream return water branch pipes. Each upstream return water branch pipe has a centrifugal pump 8 installed at its inlet. A fifth valve 3-5 is installed at the inlet and outlet of each centrifugal pump 8. A third pressure gauge 4-3 is installed on each upstream return water branch pipe. A flow meter 6 is installed on any one of the upstream return water branch pipes. The inlet ends of the two upstream return water branch pipes are connected by a sixth valve 3-6, and the outlet ends of the two upstream return water branch pipes are connected by a seventh valve 3-7. An eighth valve 3-8 is installed on each upstream return water branch pipe, and a ninth valve 3-8 is installed on each downstream return water branch pipe.

[0020] In this embodiment, a more preferred solution is as follows:

[0021] The device also includes a base 1, on which the water storage tank 2 and the circulation pipe are mounted.

[0022] A control box 9 is installed on the base 1, and the centrifugal pump 8 is electrically connected to the control box 9.

[0023] The first valve 3-1, the second valve 3-2, the third valve 3-3, the fourth valve 3-4, the fifth valve 3-5, the sixth valve 3-6, the seventh valve 3-7, the eighth valve 3-8, and the ninth valve 3-9 are all gate valves.

[0024] The flow meter 6 is a rotor flow meter.

[0025] A condensate drainage device 5 is installed on the downstream water supply main section.

[0026] An air venting device 7 is installed on the downstream return water branch pipe of the higher-positioned branch.

[0027] When the device is running, the fluid medium in the water storage tank flows out of the water storage tank outlet, first flows through the water supply pipeline, then flows through the centrifugal pump under pressure to the return water pipeline, and finally flows back to the water storage tank through the return water pipeline, and then repeats the cycle.

[0028] The aforementioned training device has functions for recognizing chemical pipelines and instruments, installing, debugging and maintaining chemical pipelines and instruments, conducting pressure tests on chemical pipeline systems, designing chemical pipeline processes, and testing the installation technology and performance of new chemical pipelines and materials.

[0029] The cognitive function of chemical pipelines and instruments is realized by relying on components such as centrifugal pumps, valves, pressure gauges, and flow meters on the internal circulation pipeline of the training device. Through observation and study of the relevant components, training is conducted on the operating principles of chemical pipelines and instruments.

[0030] The installation, commissioning, and maintenance of chemical pipelines and instruments are achieved through the entire circulating pipeline and water storage tank. The circulating pipeline consists of components such as centrifugal pumps, valves, pressure gauges, condensate draining devices, rotor flow meters, and venting devices. Training in relevant installation skills for chemical pipelines is provided through the installation and commissioning of these components. When problems arise in the training equipment, such as poor medium flow, inaccurate flow meter readings, or insufficient pump pressure, troubleshooting and maintenance of the identified faulty components provide training in chemical pipeline maintenance skills.

[0031] The pressure testing function of chemical pipeline systems relies on pipe sections, valves, and pressure gauges in the circulating pipeline. Parts of the training device are disassembled, the pipeline to be pressure tested is selected, and both ends are sealed. Pressure is then applied to the pipeline using a pressure pump until the pressure gauge reaches the specified pressure. The pressure is then stabilized and observed. This method serves as training for operating pressure testing of chemical pipeline systems.

[0032] The chemical pipeline process design function relies on the overall training device. By innovating existing circulation pipelines, it designs different circulation pipelines for different media, thereby realizing the overall process design and implementation training of chemical pipelines. After designing the new circulation pipeline process, the installation of chemical pipelines and instruments is carried out immediately, which can be linked with the aforementioned pipeline installation skills training function.

[0033] The installation technology for new chemical pipelines and the performance testing functions of new materials rely on an integrated training device. After accumulating certain experience, trainees can optimize the structure of the device and conduct hands-on practice. They can also replace materials according to design principles, such as whether new materials can achieve better circulation effects when the medium is different. Furthermore, training on preliminary performance testing of new materials can be achieved through pipeline system pressure tests.

[0034] In summary, this utility model can be used for various skills training, improve trainees' understanding and operation of various pipe sections and instruments, enhance their safety awareness during production operations, reduce safety hazards, and prevent safety accidents, thus possessing strong practicality.

[0035] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
