Description

Technical Field

[0001] The utility model relates to the application field of a water drain valve for an air storage tank used for an air compressor, in particular to a special air storage tank for an air compressor which is convenient for water drainage. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. Usually, an air compressor is equipped with an air tank, which acts like a water reservoir. The air compressor is an air source, and the air tank is a water reservoir. The air tank can set the air pressure within a certain pressure range according to the settings, buffer the fluctuation of air pressure, and reduce the number of times the air compressor is started. In addition, the air tank can also precipitate impurities, moisture and other foreign matter in the air, reducing the rust on accessories and extending the service life of the air compressor.

[0003] After long-term use, a large amount of impurities and condensed water will be deposited inside the air tank of the air compressor. Therefore, an automatic drainage device is usually installed at the bottom of the air tank, which mainly consists of a connecting pipe, a Y-type filter tube and a float drain valve. The Y-type filter tube is used to filter impurities in the condensed water in the air tank, and the float drain valve can automatically drain water. When the condensed water enters the float drain valve, the floating ball will drive the plug cover to open, thereby achieving the purpose of automatic drainage. As the condensed water is drained, the float automatically blocks the outlet due to gravity.

[0004] The condensed water deposited in the gas tank will drain automatically. The Y-type filter tube can filter out impurities in the condensed water. However, when using the Y-type filter tube, the metal filter tube in the Y-type filter tube will also accumulate a large amount of impurities. The metal filter tube needs to be removed and cleaned regularly, otherwise the metal filter tube will be blocked, which will affect the drainage effect of the gas tank. It is troublesome to clean the metal filter tube regularly. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a special air storage tank for an air compressor that is convenient for drainage, so as to solve the technical problems mentioned in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special air storage tank for an air compressor that is convenient for drainage, comprising a metal tube, the end of the metal tube is threadedly connected to a Y-type filter tube, and the other end of the Y-type filter tube is threadedly connected to a float drain valve, a valve is arranged on one side of the metal tube, and a rubber plug is arranged on the end of the valve, an inner convex ring is installed inside the metal tube, and a branch pipe is arranged at the bottom of the metal tube, and a hose is connected to the end of the branch pipe, and an interface matching the hose is arranged on the top of the float drain valve.

When the nut 803 of the Y-type filter tube 8 is opened, the condensed water can reversely flush the interior of the float drain valve 9, the interior of the Y-type filter tube 8 and the filter cartridge 804, which can not only quickly remove impurities in the filter cartridge 804, but also save water resources for cleaning.

[0038] See also Figure 2 The metal tube 1 is movably installed at the bottom of the gas storage tank by setting a four-point threaded interface 2, and the metal tube 1 is made of rust-proof metal. By setting the four-point threaded interface 2, the metal tube 1 can be movably installed at the bottom of the gas storage tank. The four-point threaded interface 2 is the most widely used.

[0039] See also Figure 3 The valve 3 is rotatably connected to the inner wall of the metal tube 1, and the valve 3 extends to the inside of the metal tube 1, and the valve 3 can drive the rubber plug 4 to rotate. By setting the valve 3, the condensed water can be controlled to enter the Y-type filter tube 8 or the branch pipe 6.

[0040] See also Figure 3 The rubber plug 4 can be rotated at different angles to seal the inner convex ring 5 and the branch pipe 6 respectively. By setting the rubber plug 4, the inner convex ring 5 and the branch pipe 6 can be sealed.

[0041] See also Figure 4 and Figure 5 The Y-type filter tube 8 includes a straight tube 801 and an inclined tube 802, and a filter cartridge 804 is installed inside the inclined tube 802, and a nut 803 is threadedly connected to the end of the inclined tube 802.

[0043] See also Figure 1 The metal tube 1, the Y-type filter tube 8, the float drain valve 9 and the gas tank are all threadedly connected, and the joints are wrapped with raw tape. By arranging raw tape at the joints of the metal tube 1, the Y-type filter tube 8 and the float drain valve 9, the sealing of the drainage device can be improved.

[0044] Embodiment 2

[0045] A special air storage tank for air compressor that is convenient for drainage, such as Figure 8As shown, a filter element 11 is arranged inside the interface 10. By arranging the filter element 11 inside the interface 10, when the hose 7 is connected to the interface 10, condensed water containing impurities will be filtered by the filter element 11, and the interior of the shell 901 and the Y-type filter tube 8 will be flushed after the impurities are removed, thereby reducing the impurities entering the interior of the float drain valve 9 and reducing the damage of the impurities to the float drain valve 9. The backwashing time is short and the number of times is not frequent, so that the impurities in the filter element 11 will not accumulate too much. Even if a lot of impurities are accumulated after a long period of flushing, it will not affect the drainage effect of the float drain valve 9.

[0046] The working principle of the utility model is as follows: raw tape is wound around the position of the quarter threaded interface 2, the metal tube 1 is installed to the bottom of the gas storage tank, and then raw tape is wound around the other end of the metal tube 1 to install the Y-type filter tube 8, and then raw tape is used to wind one end of the external thread of the Y-type filter tube 8, and the float drain valve 9 is installed.

[0047] When the drainage device is working, the rubber plug 4 is in a state of blocking the branch pipe 6, and the condensed water enters the interior of the straight pipe 801 from the metal pipe 1, and is filtered by the filter cartridge 804. Impurities adhere to the inner wall of the filter cartridge 804, and the filtered condensed water enters the shell 901. As the condensed water accumulates in the shell 901, the float 902 floats up and drives the plugging cover 903 to rotate and open, so that the condensed water is discharged from the outlet pipe 904. After the condensed water is discharged, the float 902 drops due to gravity, causing the plugging cover 903 to re-block the outlet pipe 904.

[0048] When the drainage device needs to be cleaned of impurities after being used for a period of time, open the interface 10 to connect the hose 7, then turn the valve 3 so that the rubber plug 4 closes the inner convex ring 5, and then the condensed water will enter the hose 7, and then open the nut 803 of the Y-type filter tube 8, the condensed water enters the hose 7 from the metal tube 1, and then enters the interior of the shell 901 through the interface 10. The filter element 11 can filter impurities in the condensed water. After the condensed water enters the interior of the shell 901, the inner wall of the shell 901, the float 902 and the plugging cover 903 are rinsed, and then the condensed water reversely rinses the straight pipe 801 and the filter cartridge 804, so that the impurities attached to the inner wall of the filter cartridge 804 are discharged from the port of the inclined tube 802. Timely cleaning of impurities in the filter cartridge 804 can improve the drainage effect of the drainage device.
