Description
Technical Field
[0001] The utility model relates to the technical field of drainers, in particular to a gas drainer. Background Technique
[0002] During the process of pipeline gas transportation, there will be condensate water in the transportation pipeline. In order to prevent the condensate water in the gas pipeline from entering the user end, generally a drainer is installed on the gas pipeline. The structure of the existing gas drainer generally consists of a high-pressure chamber and a low-pressure chamber. Water is contained in the high-pressure chamber and the low-pressure chamber. There is an air chamber above the water level in the high-pressure chamber and the low-pressure chamber respectively. A connecting pipe is installed between the high-pressure chamber and the low-pressure chamber; a gas drain pipe is provided in the high-pressure chamber, and a condensate water discharge pipe is provided in the low-pressure chamber. The condensate water in the gas pipeline enters the high-pressure chamber through the drain pipe, overflows to the low-pressure chamber through the connecting pipe, and is discharged from the condensate water discharge pipe on one side of the low-pressure chamber, realizing the separation and discharge of the condensate water in the gas.
[0003] The high-pressure chamber is used to discharge the condensate water in the gas. However, if the water in the low-pressure chamber flows back to the high-pressure chamber, it will cause the water level in the high-pressure chamber to rise, thereby increasing the system pressure, which may cause an overload on the design pressure of the gas pipeline and affect its safe operation. At present, the existing gas drainer does not have an anti-backflow structure on the high-pressure chamber side, so the above situation cannot be avoided. Content of the Utility Model
[0004] The purpose of the utility model is to provide a gas drainer to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A gas drainer, comprising
[0007] A drainer body, in the middle of the inner side of the drainer body, a partition is fixedly installed, and a high-pressure chamber and a low-pressure chamber are respectively arranged on both sides of the drainer body where the partition is located;
[0008] The high-pressure chamber and the low-pressure chamber are connected and communicated through an overflow pipe. The inlet of the overflow pipe is located above the middle of one side of the high-pressure chamber, and the outlet of the overflow pipe is located below the inner part of one side of the low-pressure chamber;
[0009] An anti-backflow mechanism is arranged on the outer side of the overflow pipe close to the high-pressure chamber.
[0010] Preferably, the anti-backflow mechanism includes a blocking plate, the blocking plate is movably installed outside the inlet of the overflow pipe, a spring is arranged at the top of the blocking plate and is movably connected with the high-pressure chamber, a guide rod is fixedly installed in the middle of the blocking plate, and a floating ball is arranged at the bottom end of the guide rod;
[0011] Preferably, the anti-backflow mechanism further includes a sleeve, which is arranged in the middle of the spring in the high-pressure chamber. The top of the sleeve is fixedly connected to the high-pressure chamber, and the inside of the sleeve is movably sleeved with a guide rod.
[0012] Preferably, a water inlet pipe is connected to the left side of the high-pressure chamber of the drain body. The bottom end of the water inlet pipe is close to the lower part inside the high-pressure chamber. A drain pipe is connected to the upper right side of the low-pressure chamber of the drain body, and the height of the drain pipe is equal to that of the inlet of the overflow pipe.
[0013] Preferably, an overflow port is further arranged at the upper left end of the high-pressure chamber of the drain body. The outside of the overflow port is connected to the drain pipe through an external pipe, and a one-way valve is fixedly installed in the middle of the external pipe.
[0014] Preferably, the height of the overflow port is greater than the height of the inlet of the overflow pipe.
[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0016] For this gas drain, through the cooperation of the overflow pipe, the plug plate, the spring, the guide rod and the floating ball, the condensed water enters the high-pressure chamber from the drain pipe. As the water level rises, the floating ball is pushed up. After the floating ball floats, it drives the plug plate to rise synchronously through the guide rod and compresses the spring. At this time, the outlet of the overflow pipe opens, and the increased condensed water inside the high-pressure chamber overflows into the low-pressure chamber through the overflow pipe and is then discharged through the drain pipe. When the water level inside the high-pressure chamber drops, the compressed spring rebounds to control the plug plate to reset and block the overflow pipe. In this way, when the pipeline of the drain pipe is blocked, the water inside the low-pressure chamber will not flow back into the high-pressure chamber, thereby preventing the condensed water from flowing back.
[0017] For this gas drain, through the cooperation of the overflow port, the external pipe, the one-way valve and the water inlet pipe, if the pipeline of the overflow pipe is blocked, the water level inside the high-pressure chamber continues to rise until the water level reaches the height of the overflow port, then it flows into the external pipe from the overflow port, and after opening the one-way valve, it enters the drain pipe and is finally discharged from the drain pipe or enters the low-pressure chamber. The one-way valve is provided to prevent backflow. In this way, when the inside is blocked, the condensed water in the high-pressure chamber can be discharged tightly.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0024] As Figures 1 - 4 shown, a technical solution provided by the present utility model is as follows:
[0025] A gas drainage device includes a drainage device body 1. A partition board 2 is fixedly installed in the middle of the inner side of the drainage device body 1. A high-pressure chamber 3 and a low-pressure chamber 4 are respectively arranged on both sides of the drainage device body 1 with respect to the partition board 2. The high-pressure chamber 3 and the low-pressure chamber 4 are connected and communicated through an overflow pipe 5. The inlet of the overflow pipe 5 is located above the middle of one side of the high-pressure chamber 3, and the outlet of the overflow pipe 5 is located below the inner part of one side of the low-pressure chamber 4. An anti-backflow mechanism is arranged on the outer side of the overflow pipe 5 close to the high-pressure chamber 3. The anti-backflow mechanism includes a plug plate 6. The plug plate 6 is movably installed outside the inlet of the overflow pipe 5. A spring 7 is arranged at the top of the plug plate 6 and is movably connected to the high-pressure chamber 3. A guide rod 8 is fixedly installed in the middle of the plug plate 6, and a float ball 9 is arranged at the bottom end of the guide rod 8. The anti-backflow mechanism further includes a sleeve 10. The sleeve 10 is arranged in the middle of the high-pressure chamber 3 with respect to the spring 7. The top end of the sleeve 10 is fixedly connected to the high-pressure chamber 3, and the inside of the sleeve 10 is movably sleeved with the guide rod 8. A water inlet pipe 11 is connected and communicated on the left side of the drainage device body 1 with respect to the high-pressure chamber 3. The bottom end of the water inlet pipe 11 is close to the lower part inside the high-pressure chamber 3. A drain pipe 12 is connected and communicated above the right side of the drainage device body 1 with respect to the low-pressure chamber 4. The height of the drain pipe 12 is equal to that of the inlet of the overflow pipe 5.
[0026] In this embodiment, during operation, the condensed water in the gas pipeline enters the high-pressure chamber 3 from the drain pipe 12. As the water level rises, the floating ball 9 is lifted. After the floating ball 9 floats up, it drives the plug plate 6 to rise synchronously through the guide rod 8 and compresses the spring 7. At this time, the outlet of the overflow pipe 5 opens, and the increased condensed water inside the high-pressure chamber 3 overflows from the overflow pipe 5 into the low-pressure chamber 4 and then is discharged through the drain pipe 12. When the water level inside the high-pressure chamber 3 drops, the compressed spring 7 rebounds and controls the plug plate 6 to reset and block the overflow pipe 5. In this way, when the pipeline of the drain pipe 12 is blocked, the water inside the low-pressure chamber 4 will not flow back into the high-pressure chamber 3, thus preventing the condensed water from flowing back.
[0027] As Figure 1 and Figure 3 shown, the drainer body 1 is further provided with an overflow port 13 at the upper left side of the high-pressure chamber 3. The outside of the overflow port 13 is connected to the drain pipe 12 through an external pipe 14, and a check valve 15 is fixedly installed in the middle of the external pipe 14; the height of the overflow port 13 is greater than the height of the inlet of the overflow pipe 5.
[0028] In this embodiment, if the pipeline of the overflow pipe 5 is blocked, at this time, the water level inside the high-pressure chamber 3 continues to rise until the water level reaches the height of the overflow port 13, then it flows into the external pipe 14 from the overflow port 13, and after opening the check valve 15, it enters the drain pipe 12 and finally is discharged from the drain pipe 12 or enters the low-pressure chamber 4. The check valve 15 is provided to prevent backflow. In this way, in the case of internal blockage, the condensed water in the high-pressure chamber 3 can be quickly discharged.
[0029] Working principle: During operation, the condensed water in the gas pipeline enters the high-pressure chamber 3 from the drain pipe 12. As the water level rises, the floating ball 9 is lifted. After the floating ball 9 floats up, it drives the plug plate 6 to rise synchronously through the guide rod 8 and compresses the spring 7. At this time, the outlet of the overflow pipe 5 opens, and the increased condensed water inside the high-pressure chamber 3 overflows from the overflow pipe 5 into the low-pressure chamber 4 and then is discharged through the drain pipe 12. When the water level inside the high-pressure chamber 3 drops, the compressed spring 7 rebounds and controls the plug plate 6 to reset and block the overflow pipe 5. In this way, when the pipeline of the drain pipe 12 is blocked, the water inside the low-pressure chamber 4 will not flow back into the high-pressure chamber 3; if the pipeline of the overflow pipe 5 is blocked, at this time, the water level inside the high-pressure chamber 3 continues to rise until the water level reaches the height of the overflow port 13, then it flows into the external pipe 14 from the overflow port 13, and after opening the check valve 15, it enters the drain pipe 12 and finally is discharged from the drain pipe 12 or enters the low-pressure chamber 4. The check valve 15 is provided to prevent backflow. In this way, in the case of internal blockage, the condensed water in the high-pressure chamber 3 can be quickly discharged.
