Description

Technical Field

[0001] The invention relates to the field of experimental equipment, in particular to a safety interlocking test device for a quick-opening pressure vessel. Background Art

[0002] A quick-opening pressure vessel is a pressure vessel with a nested quick-seal locking device between the end cover or head of the inlet and outlet passage and the main body. The safety interlock device is one of the important safety accessories of the quick-opening pressure vessel.

[0003] According to the special design requirements for quick-opening door pressure vessels in the "Regulations for the Supervision of Stationary Pressure Vessels" (TSG 21-2016), safety interlock devices should be installed on such vessels. The safety interlock device should meet the following requirements: 1. When the quick-opening door reaches the predetermined position, it can be operated at a higher pressure; 2. When the internal pressure of the pressure vessel is completely released, the quick-opening door can be opened. In order to ensure the safe operation of the quick-opening door pressure vessel, the safety interlock device must be functionally tested in the event of an abnormal situation, and the following two points must be met: First, if the quick-opening door is not closed in place, air intake and pressure increase are not allowed; second, if there is still pressure inside the pressure vessel, the door or cover of the quick-opening door pressure vessel cannot be opened.

[0004] like Figure 1 As shown, the principle of the safety interlock device of the quick-opening door pressure vessel is briefly described as follows: 1. Before the quick-opening door pressure vessel is operated, it is necessary to confirm whether the door or cover of the quick-opening door pressure vessel has reached the predetermined closing position. Only when the door or cover is closed to the predetermined position, the quick-opening door safety interlock device can transmit the signal of the door or cover being closed to the predetermined position to the third solenoid valve through the equipment safety interlock device signal transmission <1>. At this time, the third solenoid valve is allowed to be opened, and the gas enters the quick-opening door pressure vessel, and the quick-opening door pressure vessel starts to increase pressure. In this way, the function of the safety interlock device of the quick-opening door pressure vessel meets the first requirement specified in the regulations-when the quick-opening door reaches the predetermined position, it can increase pressure; otherwise, the third solenoid valve cannot be opened, and the gas cannot enter the quick-opening door pressure vessel. 2. After the operation of the shutter-type pressure vessel is completed, before opening the door or cover of the quick-opening pressure vessel, it is necessary to confirm whether the internal pressure of the container is completely released. Only when the internal pressure of the container is completely released, the pressure gauge used to measure the internal pressure of the container transmits the signal that the internal pressure of the container is completely released to the door or cover of the quick-opening pressure vessel through the signal transmission of the equipment safety interlock device <2>, and the door or cover of the quick-opening pressure vessel is automatically unlocked and allowed to be opened. In this way, the function of the safety interlock device of the quick-opening pressure vessel meets the second requirement stipulated in the regulations-the quick-opening door can be opened only when the internal pressure of the pressure vessel is completely released; otherwise, the door or cover of the quick-opening pressure vessel cannot be opened. Figure 1 The equipment and parts contained in it are the body of the quick-opening pressure vessel to be tested and its accessories.

[0005] At present, the functional test of the safety interlock device is mainly carried out by the gas source of the equipment itself. 3 The above), if a large amount of steam is required to achieve the pressurized working condition, even if the pressure in the kettle is very small, the destructive energy it contains is enough to cause casualties and property losses. Also, because the tester does not know whether the safety interlock device is normal or effective before testing the safety interlock device, in case the safety interlock device has failed, when the test container is under pressure, the door or cover of the quick-opening pressure vessel is opened, it is very likely that the container will cause casualties and property losses. Not only that, in this pressurized working condition, to test whether the safety interlock device meets the requirement that the quick-opening door can be opened only after the internal pressure is completely released, the door opening operation must be performed. Therefore, the traditional testing method has low safety. It can be seen that this method is neither economical nor safe. The problems with this method include cumbersome operation, no energy saving, poor safety, and a small scope of application.

[0006] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art known to a person skilled in the art. Summary of the invention

[0011] When performing a functional test on the safety interlock device under the simulation condition that the internal pressure of the quick-opening door pressure vessel is not completely released, the first pipeline system is connected to the pressure gauge of the quick-opening door pressure vessel.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1 As shown, the right side of the quick-opening door pressure vessel is connected to the quick-opening door pressure vessel safety interlock device 6, and the right side of the quick-opening door pressure vessel includes a door or cover for entering the quick-opening door pressure vessel. The top of the quick-opening door pressure vessel includes a third solenoid valve 4 and a pressure gauge 5. The third solenoid valve 4 is used for gas to enter during use, and an equipment air inlet pipe 41 is provided at the bottom. The pressure gauge 5 is used to measure the internal pressure of the quick-opening door pressure vessel, and a pressure gauge pipe port 51 is provided at the bottom. In the prior art, the third solenoid valve 4 is connected to the quick-opening door pressure vessel safety interlock device 6 through the equipment safety interlock device signal transmission (I), and the pressure gauge is connected to the quick-opening door pressure vessel safety interlock device 6 through the equipment safety interlock device signal transmission (II).

[0040] Specifically, the principle of the safety interlock device of the quick-opening pressure vessel is briefly described as follows:

[0041] Before the operation of the quick-opening door pressure vessel, it is necessary to confirm whether the door or cover of the quick-opening door pressure vessel has reached the predetermined closing position. Only when the door or cover is closed to the predetermined position, the quick-opening door safety interlock device can transmit the signal that the door or cover has been closed to the predetermined position to the third solenoid valve 4 through the equipment safety interlock device signal transmission (I). The third solenoid valve 4 is allowed to be opened at this time, and the gas will enter the interior of the quick-opening door pressure vessel through the third solenoid valve 4, and the quick-opening door pressure vessel starts to increase pressure operation. In this way, the function of the safety interlock device 6 of the quick-opening door pressure vessel meets the first requirement stipulated in the regulations-when the door or cover of the quick-opening door pressure vessel reaches the predetermined position, it can increase pressure operation; otherwise, the third solenoid valve 4 cannot be opened, and the gas cannot enter the interior of the quick-opening door pressure vessel.

[0042] After the operation of the quick-opening pressure vessel is completed, before opening the door or cover of the quick-opening pressure vessel, it is necessary to confirm whether the internal pressure of the container is completely released. Only when the internal pressure of the container is completely released, the pressure gauge 5 used to measure the internal pressure of the container transmits the signal that the internal pressure of the container has been completely released to the door or cover of the quick-opening pressure vessel through the signal transmission (II) of the equipment safety interlock device, and the door or cover of the quick-opening pressure vessel is automatically unlocked and allowed to be opened. In this way, the function of the safety interlock device 6 of the quick-opening pressure vessel meets the second requirement stipulated in the regulations-the quick-opening door can be opened only when the internal pressure of the pressure vessel is completely released; otherwise, the door or cover of the quick-opening pressure vessel cannot be opened. The equipment and components contained in the figure are the main body of the quick-opening pressure vessel to be tested and its own accessories, not the components of the test device.

[0043] In this embodiment, Figure 2 , Figure 3 As shown, the safety interlock test device for a quick-opening pressure vessel includes a first pipeline system 1, a second pipeline system 2, and an electrical control system 3; the first pipeline system 1 and the second pipeline system 2 are both connected to the electrical control system 3. Thus, the predetermined function of the program is realized. In this embodiment, a lithium battery power supply (not shown in the figure) should also be included, and the lithium battery power supply is electrically connected to the electrical control system 3, the first pipeline system 1, and the second pipeline system 2 to realize power supply. The electrical control system 3 includes a proximal control system 31 and a distal human-computer interaction system 32, the proximal control system 31 is located near the quick-opening pressure vessel, and the distal human-computer interaction system 32 is located far from the quick-opening pressure vessel, the proximal control system 31 is communicatively connected to the distal human-computer interaction system 32, and the proximal control system 31 is electrically connected to the first pipeline system 1 and the second pipeline system 2.

[0044] like Figure 2 , Figure 3 As shown, the first pipeline system 1 includes a first pipeline body, and a filter 11, an air pump 12, a first solenoid valve 13, a one-way valve 14, and a first pressure sensor 15 which are sequentially installed on the first pipeline body from the air inlet end; an exhaust pipeline is also connected between the one-way valve 14 and the first pressure sensor 15, and a second solenoid valve 16 is also connected to the exhaust pipeline. Figure 2 It can be seen that one end of the first pipeline body is the air inlet end, from which the ambient gas enters, and the other end is connected to the upper pipe opening of the third solenoid valve 4 through the inner locking air pipe fixed joint 7. The second pipeline system 2 includes a second pipeline body and a second pressure sensor 21 and a plug 22 installed on the second pipeline body; the second pipeline body and the lower pipe opening of the third solenoid valve 4 are connected to the equipment air inlet pipe opening 41 through the inner locking air pipe fixed joint 7'.

[0045] It should be noted that the first pipeline system 1 and the second pipeline system 2 are connected to the quick-opening pressure vessel at different locations when performing different tests; Figure 2 As shown, the first pipeline system 1 and the second pipeline system 2 are both connected to the third solenoid valve 4; Figure 3 As shown, only the first pipeline system 1 is connected to the pressure gauge 5. The detailed description is as follows.

[0046] like Figure 2 As shown, the safety interlock device is functionally tested when the door or cover of the simulated quick-opening pressure vessel is not fully closed (i.e., the door or cover is in an open or half-open state); the third solenoid valve 4 that controls the air intake cannot be opened according to the regulations, and the air intake into the quick-opening pressure vessel cannot be realized. This embodiment uses the test device to test whether this function of the equipment safety interlock device meets the requirements.

[0047] After the first pipeline system 1 and the second pipeline system 2 are connected to the third solenoid valve 4, the control test can be performed through the electrical control system 3. Specifically, the electrical control system 3 controls the air pump 12 to work, opens the first solenoid valve 13, sets the target pressure to 0.5 MPa, and the ambient gas is Figure 2 Enter the first pipeline system 1 in the direction shown. When the first pressure sensor 15 shows that the pressure reaches 0.5MPa, the air intake automatically stops running and maintains the pressure. During the process of increasing and maintaining pressure, the tester clicks to run the opening program of the third solenoid valve 4 of the quick-opening pressure vessel. If the first pressure sensor 15 has a stable pressure indication, and the second pressure sensor 21 has no pressure indication, it means that the safety interlock device 6 of the quick-opening pressure vessel is normal, the third solenoid valve 4 is not opened and there is no internal leakage; if the first pressure sensor 15 has a pressure indication, the second pressure sensor 21 also has a pressure indication and is close to or consistent with the indication of the first pressure sensor 15, it means that the safety interlock device 6 of the quick-opening pressure vessel is completely invalid, the third solenoid valve 4 is opened or the third solenoid valve 4 is completely invalid; if the first pressure sensor 15 has a normal pressure indication, the second pressure sensor 21 has a pressure indication but the value is smaller than that of the first pressure sensor 15, it means that there is a problem with the safety interlock device 6 of the quick-opening pressure vessel, the third solenoid valve 4 may be opened or the third solenoid valve 4 itself has a weak internal leakage.

[0048] After the air intake is completed, the pressure in the pipeline is discharged through the second solenoid valve 16, and then the first pipeline system 1 can be removed.

[0049] like Figure 3 As shown, this embodiment uses only the first pipeline system 1 to simulate the pressurized state of the quick-opening door pressure vessel (ie, the internal pressure of the quick-opening door pressure vessel is not completely released) to perform a functional test on the safety interlock device.

[0050] The traditional test method requires the entire cavity of the quick-opening pressure vessel to be pressurized by air intake. The internal pressure of the vessel acts on the pressure gauge 5. The pressure gauge 5 displays the pressure and transmits the signal of internal pressure to the safety interlock device 6 of the quick-opening pressure vessel through the signal transmission of the equipment safety interlock device (II). At this time, the door or cover of the quick-opening pressure vessel should not be opened. Otherwise, the safety interlock device fails.

[0051] In this embodiment, the first pipeline system 1 is connected to the pressure gauge pipe port 51 of the pressure gauge 5 through the inner-locking air pipe fixed joint 7, and specifically, the end of the first pipeline body is connected to the pressure gauge pipe port 51 through the inner-locking air pipe fixed joint 7. After the connection is completed, the control test can be performed through the remote human-computer interaction system 32 or the near-end control system 31. The process requires a preset running program, delayed execution (the time can be preset), and automatic exhaust stops after a certain period of operation (the time can be preset), so as to realize the directional pressurization of the pressure gauge 5 with a very small gas flux, thereby simulating the pressure condition of the quick-opening device.

[0052] It should be noted that: because this test requires the quick-opening pressure vessel to be completely closed, the quick-opening pressure vessel is a closed metal cavity, and the wireless signal cannot effectively interact in real time. Therefore, a preset method is used to allow the device to automatically run and stop. For example: the preset target pressure is 0.5MPa, the preset delay execution time is 5 minutes, and the preset pressure holding operation time is 5 minutes. The test device will start air intake and pressurization 5 minutes after the preset completion, and enter the pressure holding operation stage when the pressure increases to 0.5MPa, and start exhaust after 5 minutes of pressure holding.

[0053] After the program preset is completed, close the quick-opening pressure vessel, and after the running time is reached, observe the indication of the pressure gauge 5 of the quick-opening pressure vessel equipment. In this embodiment, the preset target pressure is 0.2MPa, and the pressure-maintaining operation time is 5 minutes. Because the pressure measuring device of the quick-opening pressure vessel body, the pressure gauge 5, is subjected to directional pressurization, the pressure gauge 5 will have the same pressure display of 0.2MPa, so as to simulate the environment where there is pressure inside the container. The indication of the pressure gauge 5 indicates that the pressure inside the container has not been completely released, and the door or cover of the quick-opening pressure vessel should not be opened. During the pressure-maintaining operation stage, click to run the quick-opening door or cover opening program. If the door or cover of the quick-opening pressure vessel is opened, it means that the safety interlock device 6 of the quick-opening pressure vessel has failed.

[0054] After the preset instruction ends, the device automatically discharges the pressure in the pipeline through the second solenoid valve 16, opens the quick-opening door pressure container, releases the connection between the inner-locking air pipe fixed joint 7 and the first pipeline system 1, and the test process ends.

[0055] This embodiment uses the safety interlock test device to test the two requirements that the safety interlock device should meet. This embodiment uses this set of test devices to safely and quickly test the functionality of the safety interlock device, and is the first in China to implement "non-destructive" functional testing of the safety interlock device of the quick-opening pressure vessel in use; the test device can use a remote wireless control system and a small amount of energy consumption to directly apply pressure to the pressure measuring device to simulate the pressurized working conditions of the quick-opening pressure vessel, thereby increasing the safety of the commissioning work; the device uses a booster device to perform directional boosting on the relevant parts of the equipment body, which can save energy by more than 95% compared with the traditional commissioning method; the booster device is fixed at the internal pipe mouth of the container by a quick-connect connector that adapts to different structural types. The device has good applicability and can be used for equipment of different structural types and materials. It has effectiveness, safety, energy saving, and applicability.

[0056] The signal wires are used to connect the components to the main controller to realize signal transmission and ensure safety; the booster device is used to perform directionally boost pressure on the relevant parts of the equipment body to achieve energy saving.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
