Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid tanks, in particular to a novel overflow check device for a liquid tank. Background Art
[0002] A liquid tank is a container for storing liquid. During production, the manufacturer will install an overflow pipe on the top of the liquid tank so that when the liquid level in the tank is too high, excess liquid can be discharged from the overflow pipe to prevent the liquid tank from being deformed by pressure.
[0003] When the liquid level in the liquid tank changes, there will be air flow between the liquid phase and the air. Generally, an air filter will be installed here to allow air circulation. However, the air filter is effective in filtering the air. However, when there is more liquid medium and the liquid medium level exceeds the breathing valve, its water flow rate is poor, which will cause the liquid tank pressure to increase, thereby causing the liquid tank to be compressed and deformed. At the same time, the overflow pipe is directly connected to the air, which will cause air to enter the liquid tank more easily from the overflow hole instead of going through the air filter. This causes impurities in the air to enter the liquid tank directly without being filtered, thereby contaminating the liquid medium in the liquid tank. 80% of the failure rate of the hydraulic system is caused by liquid medium contamination, so reducing the entry of impurities into the liquid tank is a factor that must be considered.

[0009] The connecting pipe is integrally arranged in the middle of the right side of the mounting flange, and the outer end of the connecting pipe is threadedly connected with an elbow welded pipe.
[0010] Furthermore, a fixing bolt is provided through the inner part of the outer side of the mounting flange, and the left end of the fixing bolt is connected to the overflow pipe in a threaded manner.

Obviously, the described embodiment is a part 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.
[0023] Example 1
[0024] like Figure 1 to Figure 2 As shown, the new overflow check device of the liquid tank in the embodiment of the first aspect of the utility model comprises: the overflow pipe 2 is installed at the upper right end of the liquid tank body 1, and the outside of the right end of the overflow pipe 2 is provided with a check pipe 3, the outside of the right end of the check pipe 3 is integrally fixedly installed with a mounting flange 4, the outside of the mounting flange 4 is penetrated by a fixing bolt 5, and the left end of the fixing bolt 5 is connected to the overflow pipe 2 in a threaded manner. During installation, the left end of the check pipe 3 is inserted into the inside of the right end of the overflow pipe 2, and the fixing bolt 5 is inserted from the outside of the mounting flange 4, so that the left end of the fixing bolt 5 is threadedly connected with the threaded hole opened in the overflow pipe 2, so that the check pipe 3 is fixedly installed on the right side of the overflow pipe 2 by the fixing bolt 5, and a sealing member is provided at the connection between the overflow pipe 2 and the check pipe 3 to avoid leakage at the connection;
[0025] A protrusion 8 is fixedly installed inside the mounting flange 4, and the inner side end of the protrusion 8 is connected to a connecting block 9 which is also located in the check tube 3. A spring 10 is installed on the outer side of the right end of the connecting block 9. A damper 11 which is also located on the outer side of the right end of the connecting block 9 is arranged inside the spring 10. The connecting block 9 can always keep a tight connection with the protrusion 8 under the action of the spring 10 and the damper 11, so as to prevent the air outside the liquid tank from entering the liquid tank from here, thereby preventing impurities in the air from entering the liquid tank and contaminating the liquid medium. The resistance pressure of the connecting block 9 and the spring 10 is small, so that the liquid medium can pass through the connecting block 9 from one side without resistance. When the liquid medium with an excessively high liquid level flows from the overflow tube 2 to the check tube 3, the connecting block 9 can be separated from the protrusion 8 under the action of the liquid medium, and the spring 10 and the damper 11 are compressed, so that the liquid medium can flow into the inner right end of the check tube 3 through the gap between the protrusion 8 and the connecting block 9.
[0026] A mounting plate 6 is fixedly installed on the outer side of the right end of the spring 10, and a prefabricated through hole 7 is penetrated inside the mounting plate 6, and the outer side of the left end of the mounting plate 6 is inclined inward, which is convenient for guiding the liquid medium, and the mounting plate 6 has a good installation and support effect on the spring 10 and the damper 11. The liquid medium can flow into the connecting pipe 12 through the prefabricated through hole 7. The connecting pipe 12 is integrated in the middle of the right side of the mounting flange 4, and the outer end of the connecting pipe 12 is threadedly connected with an elbow weld pipe 13. The connecting pipe 12 is connected to the elbow weld pipe 13, and the right end of the elbow weld pipe 13 is opened downward. The connection between the connecting pipe 12 and the elbow weld pipe 13 is provided with a seal. When in use, the recovery device can be installed on the outer side of the lower end of the elbow weld pipe 13, and the overflowing liquid medium can flow into the elbow weld pipe 13 through the connecting pipe 12, and flow downward to the recovery device at the elbow.
