Description

Technical Field

[0001] This utility model belongs to the field of gas pipeline safety detection technology, specifically relating to a gas drain cleaner drain valve tightness detector. Background Technology

[0002] Gas drainers, as important auxiliary equipment in gas pipeline systems, are mainly used to collect and drain condensate and contaminants from the pipelines, ensuring unobstructed flow. The condensate collected by drainers for coke oven gas, blast furnace gas, and converter gas contains chemical components or particulate impurities, requiring regular cleaning to maintain normal drainage function and prevent water accumulation in the pipelines. However, ensuring effective isolation between the gas and the drainer during cleaning is a core requirement for safe operation.

[0003] In existing technologies, isolation is typically achieved by closing the primary and secondary valves and then installing blind flanges. However, this method has significant drawbacks: on the one hand, the blind flange installation process is risky and time-consuming, and can easily lead to secondary safety accidents due to improper operation; on the other hand, existing isolation methods cannot achieve rapid and effective isolation, which not only restricts cleaning efficiency but also increases safety risks, making it difficult to meet the needs of optimized personnel and efficient operations. Utility Model Content

[0004] To address the problems of low isolation efficiency and high safety risks during the cleaning of gas drainers in existing technologies, this utility model provides a gas drainer downpipe valve tightness detector. During drainer cleaning, a connecting pipe and a water injection pipe are added between the first and second valves of the downpipe. Sealing liquid is injected between the first and second valves through the water injection pipe, and the liquid level in the connecting pipe is detected by a level gauge, allowing for accurate assessment of the sealing performance of the second valve. This utility model achieves rapid and safe isolation through water sealing and real-time monitoring technology, improving operational efficiency.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a gas drain cleaner downpipe valve tightness detector, including a gas pipeline, a downpipe, a drainer, a connecting pipe, a water injection pipe and a level gauge;

[0006] The downpipe is vertically installed below the gas pipeline, and its two ends are connected to the gas pipeline and the drainer, respectively.

[0007] The downpipe is equipped with a first valve and a second valve from top to bottom;

[0008] The connecting pipe and the water injection pipe are located between the first valve and the second valve, and both ends of the connecting pipe are connected to the downpipe.

[0009] The level gauge is installed at the upper end of the connecting pipe;

[0010] The water injection pipe is connected to the downpipe, and a third valve is installed on the water injection pipe.

[0011] Preferably, this utility model also includes an alarm;

[0012] The level gauge is connected to an alarm. The level gauge monitors the liquid level in the connecting pipe. When the first and second valves are not tightly closed and the liquid level is lower than a preset value, the alarm will sound to alert the user and prevent the valve seals and water seals from failing and causing danger. This invention utilizes the linkage between the water seal and the valves to isolate gas, and can monitor the water level in real time through the level gauge. When the water level is lower than a safe threshold, an alarm will sound immediately, eliminating the risk of gas leakage due to valve seal failure. Simultaneously, the detection process can evaluate valve performance and guide equipment maintenance plans.

[0013] In a preferred embodiment of this invention, a cleaning port is provided on the side wall of the drainer, and the cleaning port is sealed by a sealing bolt or a valve.

[0014] The cleaning port is located at the lower end of the drain. By inserting a flushing gun through the cleaning port, the bottom of the drain can be flushed.

[0015] In a preferred embodiment of this invention, the drainer has multiple cleaning ports on its side wall.

[0016] The cleaning ports are arranged in a ring around the circumference of the drain. The ring-shaped cleaning ports at the bottom of the drain allow for cleaning of sediment from multiple directions, resulting in better cleaning.

[0017] Preferably, the two ends of the connecting pipe are detachably mounted on the downpipe to facilitate the installation and replacement of the connecting pipe.

[0018] In a preferred embodiment of this utility model, the downpipe is provided with two connecting pipes, and the ends of the connecting pipes are provided with quick-connect male connectors;

[0019] The connecting pipe is provided with quick-connect female connectors at both ends that match the quick-connect male connectors;

[0020] A fourth valve is installed on the connecting pipe. Two connecting pipes are installed on the drain pipe, using quick-connect male and female connectors for easy and quick installation. When replacing the connecting pipe, the fourth valve can be used to seal the connecting pipe to prevent gas leakage.

[0021] In a preferred embodiment of this invention, the level gauge is a tuning fork switch.

[0022] Preferably, the water injection pipe is provided with a quick-connect fitting at its end, which allows it to be quickly connected to a water delivery pipe.

[0023] Compared with existing technologies, the beneficial effects of this utility model are as follows: In the gas drainer cleaning downpipe valve tightness detector of this utility model, the downpipe is vertically installed below the gas pipeline, and both ends of the downpipe are connected to the gas pipeline and the drainer, respectively. A first valve and a second valve are installed on the downpipe from top to bottom. A connecting pipe and a water injection pipe are sequentially installed between the first and second valves from top to bottom, with both ends of the connecting pipe connected to the downpipe. The water injection pipe is connected to the downpipe and has a third valve. A level gauge is also installed at the upper end of the connecting pipe. This utility model eliminates the need to disassemble the downpipe. By using a water seal between the first and second valves instead of a traditional blind flange, it reduces installation steps and tool dependence, significantly reducing workload. This utility model utilizes the water seal and valve linkage to isolate the gas and can monitor the water level in real time through the level gauge, eliminating the risk of gas leakage due to valve seal failure. Simultaneously, the detection process can evaluate valve performance and guide equipment maintenance plans. Attached Figure Description

[0029] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0030] like Figure 1 and Figure 2 As shown, a gas drain cleaner downpipe valve tightness detector includes a gas pipeline 1, a downpipe 2, a drainer 3, a connecting pipe 4, a water injection pipe 5, and a level gauge 6.

[0031] The downpipe 2 is vertically installed below the gas pipeline 1, and its two ends are connected to the gas pipeline 1 and the drainer 3, respectively.

[0032] The downpipe 2 is equipped with a first valve 100 and a second valve 200 from top to bottom.

[0033] The connecting pipe 4 and the water injection pipe 5 are arranged sequentially from top to bottom between the first valve 100 and the second valve 200, and the two ends of the connecting pipe 4 are respectively connected to the downpipe 2.

[0034] The level gauge 6 is installed at the upper end of the connecting pipe 4.

[0035] The water injection pipe 5 is connected to the downpipe 2, and a third valve 300 is installed on the water injection pipe 5. A quick-connect coupling is provided at the end of the water injection pipe 5.

[0036] The gas drain cleaner's drain pipe valve tightness detector also includes an alarm 7. The alarm 7 is installed at the upper end of the connecting pipe 4.

[0037] The level gauge 6 is connected to the alarm 7. The control method of the alarm 7 is implemented using existing software. The specific method is not within the protection scope of this utility model and will not be described in detail here. Those skilled in the art can set it themselves as needed.

[0038] The drain 3 has a cleaning port 31 on its side wall, which is sealed by a sealing bolt or a valve.

[0039] The cleaning port 31 is located at the lower end of the drainer 3.

[0040] The drainer 3 has multiple cleaning ports 31 on its side wall. Each chamber of the drainer 3 corresponds to at least one cleaning port 31.

[0041] The cleaning ports 31 are arranged in a ring around the drain 3.

[0042] The two ends of the connecting pipe 4 are detachably mounted on the downpipe 2.

[0043] The downpipe 2 is provided with two connecting pipes 21, and the ends of the connecting pipes 21 are provided with quick-connect male connectors 8.

[0044] The connecting pipe 4 is provided with quick-connect female connectors 9 at both ends that match the quick-connect male connector 8.

[0045] A fourth valve 400 is provided on the connecting pipe 21.

[0046] The level gauge 6 is a tuning fork switch.

[0047] During the drain cleaning process, after closing the second valve, a water column of a specific height is injected between the first valve 100 and the second valve 200 to form a water seal to isolate the gas from the drain. At the same time, the water level is monitored in real time by a level gauge to prevent safety hazards caused by the failure of the water seal.

[0048] Operating Procedure: When the drain needs cleaning, close the second valve 200. Connect the connecting pipe 4, level gauge 6, and alarm 7 to the downpipe 2. Turn on the alarm 7; it will sound an alarm when there is no water. Fill the drain with water through the water inlet pipe 5. The alarm will stop when the water level exceeds the level gauge 6. If the second valve 200 malfunctions and leaks, the alarm 7 will sound an alarm when the water level drops below the detection probe of the level gauge 6.

[0049] Water is then injected through the water injection pipe 5 to ensure that the second valve 200 is in conjunction with the water, so that the gas pipeline 1 is completely isolated from the drainer 3, and the drainer 3 is cleaned through the cleaning port 31.

[0050] 1. Equipment commissioning phase

[0051] Close the second valve 200 on the downpipe, connect the detection device to the downpipe via the quick-connect device, and switch the detection mode to "water alarm". Slowly fill the water supply pipe 5 with water. When the water level reaches the detection position of the water level switch, the alarm 7 will trigger, confirming that the equipment is functioning normally.

[0052] 2. Water seal establishment stage

[0053] After continuing to fill with water to the set height, close the first valve 100 to form a water seal between the first valve 100 and the second valve 200. Switch the detection mode to "no water alarm" and begin the formal cleaning process.

[0054] 3. Real-time monitoring and emergency response

[0055] If alarm 7 sounds during the cleaning process, it indicates that the water level is below the safety threshold and water must be added immediately through water injection pipe 5 to maintain the water seal height. If the water level drops abnormally (such as dropping below the detection position in a short time), it is determined that the second valve 200 is seriously inadequate in terms of tightness and the operation must be stopped immediately and the second valve 200 replaced.

[0056] The switching of detection modes in the above embodiments can be controlled by those skilled in the art based on existing software algorithms, and the specific methods are not described in detail in this embodiment.

[0057] This invention breaks through the technical bottleneck of traditional blind plate partitions. Through an innovative solution of "water sealing + intelligent monitoring," it simplifies the operation process and reduces labor intensity while ensuring the safety of gas drainer cleaning operations, providing an efficient and reliable technical solution for the field of gas pipeline maintenance. Its modular design is compatible with various specifications of drainers and has broad engineering application prospects. In this embodiment, real-time data feedback ensures the continuity of the cleaning process, improving overall work efficiency by more than 30%.
