[0037] The present application will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made. These all belong to the protection scope of the present application.

[0038] Referring to Figure 1 As shown, a visible magnetic suction floating ball type drain valve according to an embodiment of the present application includes: a liquid storage tank housing 1, a floating ball valve, a ball valve 9, and a cylinder 8.

[0039] The liquid storage tank housing 1 is made of visible material for observing the water level and water level conditions; an air inlet 14 and a drain outlet 16 are provided on the connecting flange of the liquid storage tank housing 1; the floating ball valve is located inside the liquid storage tank housing 1 for controlling the opening and closing of the air inlet 14; the ball valve 9 is arranged at the drain outlet 16 for controlling the opening and closing of the drain outlet 16; one end of the cylinder 8 is communicated with the air inlet 14, and the other end is connected to the ball valve 9 for pushing the ball valve 9 to open the drain outlet 16 when the air inlet 14 is opened.

[0040] In the present application, by selecting a visible material for the liquid storage tank housing 1 of the drain valve, the water level and impurities in the water can be directly observed. A floating ball valve is arranged inside the liquid storage tank housing 1. Through the floating ball valve and the cylinder 8, the control air path and the drain path in the automatic drain valve are interrelated and operate. When the external air source controlling the intake air enters the floating ball valve from the air inlet 14, as the water level in the liquid storage tank slowly rises through the water inlet 15, the floating ball valve controls the valve core 6 to open the air inlet 14, the control air source enters the cylinder 8, and the ball valve 9 is pushed to open to achieve drainage; when the water level slowly drops, at the same time the floating ball valve drops to control the valve core 6 to close the air inlet 14, and the cylinder 8 and the ball valve 9 are also closed to achieve stopping drainage. In this way, drainage can be automatically cycled according to the height of the water level.

[0041] Specifically, during the execution process, the floating ball valve is located at a lower position inside the liquid storage tank housing 1. At this time, the air inlet 14 is closed by the floating ball valve, and the drain outlet 16 is in a closed state through the ball valve 9. As the liquid is continuously added through the water inlet 15, the water level in the liquid storage tank gradually rises. When the water level reaches the set start height of the floating ball valve, the floating ball valve starts to rise due to the buoyancy effect. During the rising process of the floating ball valve, it gradually disengages from the closed position of the air inlet 14, so that the air inlet 14 is opened. At this time, external air enters the cylinder 8 through the air inlet 14, pushing the piston of the cylinder 8 to move, and then driving the ball valve 9 to open the drain outlet 16 through the link mechanism to achieve drainage; as the liquid is discharged, the water level in the liquid storage tank gradually drops. When the water level is lower than the set reset height of the floating ball valve, the floating ball valve drops under the action of gravity to re-close the air inlet 14. At the same time, the cylinder 8 returns to its original position due to the loss of gas pressure, driving the ball valve 9 to close the drain outlet 16 and return to the initial state.

[0042] In the above embodiment, the visible material of the liquid storage tank housing 1 is a visible semi-transparent material, which is formed by winding glass fiber and epoxy resin.

[0043] Specifically, a visible semi-transparent material is selected for the liquid storage tank of the automatic drain valve. This visible composite material pipe is formed by winding glass fiber and epoxy resin, and has the characteristics of high strength, corrosion resistance, and semi-transparent visibility, enabling direct observation of the water level and impurities in the water.

[0044] In some possible embodiments, the float valve includes a float 2 and a valve core 6; the float 2 can rise and fall with the water level in the liquid storage tank housing 1; one end of the valve core 6 is connected to the float 2, and the other end is located at the air inlet 14, and is used to control the opening and closing of the air inlet 14 when the float 2 rises and falls.

[0045] As Figure 1 shown, specifically, during the execution process, in the liquid storage tank housing 1, the float valve is in the initial position. At this time, the float 2 floats above a relatively low water level. One end of the valve core 6 is fixedly connected to the float 2, and the other end tightly covers the air inlet 14 to ensure that the air inlet 14 is in a closed state. As the liquid in the liquid storage tank housing 1 is continuously added through the water inlet 15, the water level gradually rises. Due to the buoyancy force, the float 2 floats upward as the water level rises; during the rising process of the float 2, the valve core 6 is driven to move together through the connecting component, causing the valve core 6 to gradually leave the air inlet 14. When the valve core 6 leaves the air inlet 14, external air or a specific gas enters the pipeline connected to the cylinder 8 through the air inlet 14, and the gas starts to enter the cylinder 8. Then, the ball valve 9 is pushed to open the drain port 16 through the link mechanism to achieve the purpose of draining water. As the water level drops, the float 2 of the float valve starts to gradually drop, driving the valve core 6 to close the air inlet valve. At the same time, the cylinder 8 and the ball valve 9 return to their original positions.

[0046] In some possible embodiments, the float valve further includes: a magnet 4 and a magnetically attractable gasket 3; the magnet 4 and the magnetically attractable gasket 3 are arranged between the float 2 and the valve core 6; one end of the magnet 4 is connected to one end of the valve core 6, and the other end is magnetically connected to one end of the magnetically attractable gasket 3; the other end of the magnetically attractable gasket 3 is connected to the float 2, and is used to magnetically connect the magnetically attractable gasket 3 and the magnet 4 when the float 2 rises and falls, and control the valve core 6 to open or close the air inlet 14.

[0047] As Figure 3As shown, the magnetically attractable gasket 3 is connected to the floating ball 2 by a connecting rod. When the floating ball 2 rises, the magnetically attractable gasket 3 descends. When the floating ball 2 descends, the magnetically attractable gasket 3 rises. During the descent of the magnetically attractable gasket 3, it is magnetically connected to the magnet 4. The valve core 6 is arranged on the magnet 4. When the magnet 4 and the magnetically attractable gasket 3 reach a certain distance, the magnetically attractable gasket 3 on one side of the magnet 4 moves, driving the valve core 6 to open the air inlet 14, allowing gas to enter the cylinder 8. The connecting rod mechanism at the other end of the cylinder 8 moves, driving the ball valve 9 to open the drain port 16 to achieve drainage. As the water level drops, the floating ball 2 moves downward, the magnetically attractable gasket 3 moves upward, the magnet 4 separates from the magnetically attractable gasket 3, the valve core 6 closes the air inlet 14, and the cylinder 8 and the ball valve 9 return to their original positions.

[0048] In some possible embodiments, the float valve further includes: a sealing gasket 5 and a flap 7. The sealing gasket 5 is connected to the valve core 6 and is used to seal the air inlet 14. The magnet 4 is fixed to the upper part of one side inside the flap 7, and the valve core 6 is fixed to the bottom of the other side of the flap 7. The flap 7 is movable under the magnetic connection of the magnet 4 and the magnetically attractable gasket 3, and the valve core 6 controls the opening and closing of the air inlet 14 along with the flap 7.

[0049] As Figure 1 and Figure 3 As shown, a sealing gasket 5 is provided between the valve core 6 of the float valve and the air inlet 14 to ensure the sealing state of the air inlet 14 when it is closed. A movable flap 7 is arranged at one end of the float valve, and the magnet 4 and the valve core 6 are fixed on the flap 7. When the floating ball 2 of the float valve rises with the water level, the magnetically attractable gasket gradually approaches the magnet 4. Under the action of the magnetic field of the magnet 4, the flap 7 moves, driving the valve core 6 to open the air inlet 14, controlling the air source to enter the cylinder 8, and pushing the ball valve 9 to open through the connecting rod mechanism of the cylinder 8 to achieve drainage. When the water level slowly drops, and at the same time the magnetically attractable gasket 3 also slowly moves away from the magnetic field of the magnet 4, the float valve closes at this time, controlling the cylinder 8 and the ball valve 9 to also close, achieving the stop of drainage. In this way, drainage can be automatically cycled according to the height of the water level.

[0050] Specifically, a visible magnetic suction floating ball type drain valve of the present utility model is not only a necessary measure to remove moisture and impurities and improve the quality of compressed air, but also the key to preventing the corrosion of the air storage tank, ensuring the stable operation of the equipment and extending the service life. This valve mainly consists of a visible composite material pipe, a floating ball 2, a magnetically absorbable gasket 3, a magnet 4, a sealing gasket 5, a valve core 6, a flap 7, a cylinder 8, a ball valve 9, etc. The structural features of this valve are as follows: A visible material is selected for the liquid storage tank of the automatic drain valve. This visible composite material pipe is formed by winding glass fiber and epoxy resin, and has the characteristics of high strength, corrosion resistance, and semi-transparent visibility, enabling the intuitive observation of the water level and impurities in the water; The connection between the floating ball valve and the valve core 6 is through a magnetic flexible soft connection. When the floating ball 2 rises with the water level, the magnetically absorbable gasket 3 slowly approaches the magnetic field of the magnet 4, and then under the action of the magnetic field, the valve core 6 is opened, controlling the air circuit to push the cylinder 8 and the ball valve 9 to open, realizing automatic drainage. When the water level drops to a certain level, the floating ball 2 also drops with the water level. At the same time, the magnetically absorbable gasket 3 also slowly moves away from the magnetic field of the magnet 4. After moving away a certain distance, the magnetic force becomes smaller. At this time, the valve core 6 automatically closes, and at the same time, the cylinder 8 and the ball valve 9 close, realizing the stop of drainage.

[0051] In some possible embodiments, an air filter 10 is further included, which is arranged at the air inlet 14 for filtering air.

[0052] By arranging the air filter 10 at the air inlet 14, impurities in the air are prevented from entering the air circuit, causing blockage of the air circuit, and the service life of the drain valve is extended.

[0053] In some possible embodiments, a manual drain valve 11 is further included and is communicated with the air inlet 14 for manually closing or opening the air inlet 14.

[0054] By arranging the manually communicated manual drain valve 11 at the air inlet 14, drainage can be achieved through the manual drain valve 11 when the air circuit is blocked or the floating ball valve is abnormal.

[0055] In the above embodiment, one end of the manual drain valve 11 is communicated with the air inlet 14, and the other end is communicated with the cylinder 8.

[0056] As Figures 1 to 2 shown, specifically, there are multiple manual drain valves 11, which are respectively connected to the internal air intake channel. The two manual drain valves 11 are externally connected through a pipeline. One of the manual drain valves 11 is communicated with the cylinder 8. When the floating ball valve is damaged, drainage can be achieved through the manual drain valve 11, and at the same time, the air circuit can also be controlled to be unblocked through the manual drain valve 11 to avoid blockage.

[0057] In some possible embodiments, it further includes a left flange 12 and a right flange 13, which are respectively arranged at both ends of the liquid storage tank housing 1 for fixing the liquid storage tank housing 1; an air inlet 14 is arranged at the top of the left flange 12 and is communicated with an external air source; a drain port 16 is arranged at the bottom side of the right flange 13.

[0058] As Figure 2 shown, in a specific embodiment, it includes a control air circuit system and a main drainage path system. A control air circuit system is formed between the air inlet 14 and the cylinder 8, and a main drainage path system is formed between the water inlet 15 and the drain port 16. The two are associated and act on each other through a float valve. The drain port 16 of the air compressor storage pipe is connected to the right flange 13. When the control air source enters the float valve from the filter, as the water level slowly rises, the magnetically attractable gasket 3, under the action of magnetic force, makes the flap 7 move upward, opening the valve core 6 (the float valve opens), and the control air source enters the cylinder 8, pushing the ball valve 9 to open to achieve drainage; when the water level slowly drops, and at the same time the magnetically attractable gasket 3 also slowly moves away from the magnetic field of the magnet 4, at this time the float valve closes, and the control cylinder 8 and the ball valve 9 also close to achieve stopping drainage. In this way, drainage can be automatically cycled according to the height of the water level.

[0059] In the above embodiment, the liquid storage tank housing 1 further includes a water inlet 15, which is arranged on one side of the left flange 12 and the right flange 13 and is communicated with the liquid storage tank housing 1 for water inlet.

[0060] As Figure 4 shown, the working principle of this application is as follows: First, an air filter 10 is provided between the air source inlet and the float valve to filter impurities in the air. A manual reversing valve, that is, a manual drain valve 11, is also provided at the air outlet of the air filter 10. One end is communicated with the cylinder 8, and the air outlet of the float valve is also communicated with the cylinder 8. The water inlet 15 is arranged on one side of the left and right flanges. When passing through the water inlet 15, the float ball 2 of the float valve controls the valve core 6 to open or close the air inlet 14 as the water level rises, controlling the external source gas to enter the cylinder 8 and driving the ball valve 9 to open the drain port 16 to achieve drainage. This application is mainly developed based on the market demand situation, aiming to develop an automatic drain valve suitable for observing the water level and the situation of impurities in water, having a long service life, and being energy-saving and economical in the drainage system of the air compressor storage tank. This automatic drain valve has a broad market prospect and a large demand, and can be applied to the automatic drainage of condensate water in most air compressor storage tanks on the market.

[0061] A visible magnetic adsorption floating ball type drain valve of the present application is applied to the automatic discharge of condensed water in an air storage tank of an air compressor system; after installing this automatic drain valve, the water level and impurities in the water in the automatic drain valve can be visually observed, and some early faults of the equipment can be detected in time, playing a preventive role; the magnetic adsorption flexible soft connection structure reduces the failure rate, thereby shortening the downtime, saving operation and maintenance costs, and greatly extending the service life of the automatic drain valve; it has a wide range of applications and can be applied to the drainage of most air compressor air storage tanks on the market.

[0062] The specific embodiments of the present application have been described above. It should be understood that the present application is not limited to the above specific implementation manners, and those skilled in the art can make various deformations or modifications within the scope of the claims, which does not affect the essence of the present application. The above preferred features can be used in any combination without conflict.
