Description

Technical Field

[0001] The utility model relates to the chemical industry field, in particular to an emergency disposal simulation training device for valve pipe fittings leakage. Background Art

[0002] A certain liquid belongs to hazardous chemicals and is generally stored in a storage tank. During storage and use, due to reasons such as equipment aging and damage, different degrees of leakage often occur. If not handled properly, secondary disasters such as explosion, fire, poisoning, chemical burns, and asphyxiation will occur.

[0003] The large leakage phenomenon of this liquid is that the medium continuously gushes out and flows out in a line. Large leakage generally occurs at the equipment connection, which is caused by the aging and damage of the sealing components. The valve pipeline is a pipeline device for transporting a certain liquid. Due to the relatively frequent use of pneumatic ball valves, problems such as corrosion, aging, loosening, and scratches are likely to occur at the flange connection or the sealing gasket. Due to the fast leakage rate, large leakage volume, and difficult decontamination treatment of large leakage, the risk of secondary disasters is very high. It is necessary to design a disposal practice device for this situation for simulation operation practice to improve the students' emergency disposal ability. Content of the Utility Model

[0036] Any reference to directions and orientations in the description of the embodiments herein is for convenience of description only and should not be construed as any limitation to the protection scope of the present utility model. The following description of the preferred embodiments involves combinations of features, which may exist independently or in combination. The present utility model is not particularly limited to the preferred embodiments. The scope of the present utility model is defined by the claims.

[0037] Large leaks generally occur at the connections of equipment and are caused by the aging and damage of the sealing components. The designed large leak simulation point is located between the valve and the pipeline, and the damaged part is the gasket between the valve and the pipeline. The designed scenario is that the gasket suddenly breaks and leaks when injecting liquid. The specific location is selected at the flange where the pneumatic valve is connected to the pipeline and at the pneumatic valve body; the equipment for simulating the leakage scenario is located at the liquid injection port and is an important equipment for controlling the injected liquid. If a leakage failure occurs in this equipment, it will have a direct impact on the entire liquid injection operation and is a very representative failure point.

[0038] As Figure 1 and Figure 2 shown, an emergency disposal simulation training device for valve and pipe fittings leakage in an embodiment of the present utility model includes an operation cabinet 1, a liquid tank 2, a gas cylinder 3, a leakage simulation pipeline 4, a pipeline switching control valve, a simulated medium injection pipeline 10, and a gas detection pipeline.

[0039] The liquid tank 2 is arranged inside the operation cabinet 1, and a simulated medium is arranged in the liquid tank 2. During practice, the liquid level of the simulated medium stored in the liquid tank 2 is at the position from 1 / 3 to 2 / 3 of the volume of the liquid tank 2.

[0040] The gas cylinder 3 is arranged on the side of the operation cabinet 1 and is communicated with the liquid tank 2 through a gas source valve 34 for supplying gas to the liquid tank 2 to drive the simulated medium to flow out of the liquid tank 2.

[0041] Further, a pressurizing pipeline 31 is provided between the gas cylinder 3 and the inlet of the liquid tank 2. A pressure increasing valve 32, a pressure reducing valve 33, a gas filter 35 and a gas source pressure gauge 36 are provided on the pressurizing pipeline 31. The pressure increasing valve 32, the pressure reducing valve 33 and the gas source pressure gauge 36 are electrically connected to the operation cabinet 1. The pressure increasing valve 32 is used to pressurize the gas introduced into the liquid tank 2. The pressure reducing valve 33 is used to reduce the pressure of the pressurizing pipeline 31 when the pressure in the pressurizing pipeline 31 is too high. The gas filter 35 is used to filter out tiny impurity particles in the gas introduced into the liquid tank 2 to avoid affecting the service life of the pipeline and the liquid tank 2 due to the tiny impurity particles.

[0042] Further, a liquid tank pressure gauge 21, a liquid level gauge 22 and a liquid inlet valve 23 are provided on the liquid tank 2; a liquid outlet valve 24 and a liquid outlet filter 25 are successively connected to the liquid outlet of the liquid tank 2. The liquid tank pressure gauge 21 is used to monitor the gas pressure in the liquid tank 2 in real time. The liquid level gauge 22 is used to monitor the liquid level height of the simulated medium in the liquid tank 2. A gas release valve 26 is provided on the liquid tank 2. The liquid tank pressure gauge 21, the liquid level gauge 22, the liquid inlet valve 23, the liquid outlet valve 24 and the gas release valve 26 are electrically connected to the operation cabinet 1.

[0043] A first pneumatic valve 5 and a second pneumatic valve 6 are provided on the leakage simulation pipeline 4. The first pneumatic valve 5 and the second pneumatic valve 6 are installed on the leakage simulation pipeline 4 through flanges. A first damaged sealing element is provided inside the flange of the first pneumatic valve 5, serving as the first leakage point; a second damaged sealing element is provided inside the valve body of the second pneumatic valve 6, serving as the second leakage point. The first damaged sealing element is the flange gasket of the first pneumatic valve 5, and the second damaged sealing element is the valve body gasket of the second pneumatic valve 6.

[0044] The built leakage simulation pipeline 4 is consistent with the liquid injection pipeline in the pipeline system of the actual application scenario. The first pneumatic valve 5 and the second pneumatic valve 6 can adopt DN100 stainless steel pneumatic ball valves. At the same time, to improve the authenticity and immersion of the built scenario, DN100 stainless steel components can be used to build the liquid return pipeline, and DN50 stainless steel pipes can be used to build the detoxification pipeline, the gas return pipeline, etc.

[0045] The outlet end of the pipeline switching control valve is connected to the inlet end of the leakage simulation pipeline 4. The inlet end of the simulated medium injection pipeline 10 is connected to the liquid outlet of the liquid tank 2. The outlet end of the simulated medium injection pipeline 10 is connected to the first inlet end of the pipeline switching control valve. The inlet end of the gas detection pipeline is connected to the gas supply end of the gas cylinder 3. The outlet end of the gas detection pipeline is connected to the second inlet end of the pipeline switching control valve. The gas source valve 34 and the pipeline switching control valve are electrically connected to the operation cabinet 1.

[0046] The simulated medium injection pipeline 10 is used to inject the simulated medium into the leakage point. The air detection pipeline is used to supply air to the leakage point for air detection after the damaged sealing element at the leakage point is processed. The pipeline switching control valve can switch the connection between the simulated medium injection pipeline 10 and the air detection pipeline and the leakage simulation pipeline 4, so as to supply the simulated medium or air to the leakage point.

[0047] Furthermore, an electromagnetic valve 101 and a regulating valve 102 are provided on the simulated medium injection pipeline 10. The electromagnetic valve 101 and the regulating valve 102 are electrically connected to the operation cabinet 1. By respectively adjusting the on-off of the simulated medium injection pipeline 10 and the flow rate of the simulated medium in the simulated medium injection pipeline 10 through the electromagnetic valve 101 and the regulating valve 102, the regulation of the leakage amount at the leakage point is realized.

[0048] Furthermore, a simulated pipeline pressure gauge is provided on the leakage simulation pipeline 4, and the simulated pipeline pressure gauge is used to detect the pressure in the leakage simulation pipeline 4 in real time.

[0049] The air source valve 34 and the pipeline switching control valve are electrically connected to the operation cabinet 1, which is convenient for the full-automatic control of the emergency disposal simulation training process through the operation cabinet 1.

[0050] Furthermore, the simulation training device further includes a base 9, which is used to support the operation cabinet 1, the gas cylinder 3 and the leakage simulation pipeline 4. Transfer devices such as transfer wheels are provided on the base 9, which is convenient for the transfer of the simulation training device, so as to meet the environmental requirements under various simulation training exercises or teaching scenarios. A liquid leakage collection device is provided on the base 9, and the liquid leakage collection holes of the liquid leakage collection device are arranged below the leakage point, and can collect the liquid leakage at the leakage point.

[0051] The simulated product adopts a modular process. The base can be spliced and combined by two parts of 1500mm * 1200mm. All pipelines and valves are detachable, which is convenient for transportation and reinstallation. The base is covered with a stainless steel drainage grid, which increases the rigidity of the whole base while realizing drainage and anti-slip. The pipeline adopts a stainless steel pipe with mirror polishing, which is beautiful and practical.

[0052] Furthermore, the operation cabinet 1 includes a cabinet body and an operation panel arranged on the cabinet body. The operation panel is provided with a leak point selection button 11, an exercise indicator light 12 and an exercise control button 13. The exercise indicator light 12 is set corresponding to several steps of the emergency disposal one by one.

[0053] Furthermore, the simulation training device further includes a smoke simulation system and a light simulation system. The smoke simulation system includes a smoke pipeline, one end of which is connected to a smoke machine, and the other end is arranged at the leakage point. The smoke machine and the light simulation system are controlled by the operation cabinet 1 and are used to simulate the smoke and light in a real leakage scene.

[0054] The working principle of the present utility model is as follows:

[0055] The simulated liquid flow comes from the liquid tank 2 in the operation cabinet 1. Before the exercise, the simulated leakage medium is poured into the liquid tank 2 in the operation cabinet 1. The poured simulated medium accounts for about half of the volume of the liquid tank 2. Compressed gas in the gas cylinder 3 is used to pressurize the liquid tank 2, and the compressed gas in the liquid tank 2 provides power for the simulated medium. When the control valve of the liquid tank 2 is opened and a damaged sealing element is placed inside the flange of the first pneumatic valve 5 at the leakage point, the simulated medium is extruded out through the water outlet of the liquid tank 2. The extruded simulated medium enters the leakage simulation pipeline 4 through the liquid outlet valve 24 and the liquid outlet filter 25, and is transported to the first pneumatic valve 5 and leaks from the flange of the first pneumatic valve 5.

[0056] The liquid flow control is achieved through the solenoid valve 101 and the leakage regulating valve 102. The leakage regulating valve 102 is used to regulate the leakage speed of the simulated medium. The valve pipe leakage system finally presents the effect of large-scale leakage under the combined adjustment of the air pressure in the liquid injection pipeline 4, the adjustment opening of the leakage regulating valve 102, and the scratch of the flange gasket inside the first pneumatic valve 5. In the air inspection link, the connection between the leakage simulation pipeline 4 and the simulated medium injection pipeline 10 is cut off through the pipeline switching control valve, so that the air inspection pipeline is connected to the leakage simulation pipeline 4, and air is supplied to the leakage point for air inspection. If the treatment of the leakage point is unqualified, it can be detected by the soap bubble method during the air inspection. At the same time, it can be detected whether there is still leakage in the simulated medium injection pipeline 10 through the indication of the simulated pipeline pressure gauge.

[0057] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
