Description

Technical Field

[0001] This utility model relates to the field of water discharge device technology, specifically to an automatic water discharge valve device for water discharge devices. Background Technology

[0002] The key to coal mine gas control lies in gas drainage. As the depth of gas drainage boreholes increases, the water content of the coal seam generally increases accordingly. Water accumulation in the gas drainage pipeline becomes a major factor affecting the improvement of the gas drainage rate. The automatic water drainer in the gas drainage borehole manifold and its auxiliary pipelines constitute the primary water drainage facility of the drainage pipeline and are also the most important water drainage measure. The effectiveness of its water drainage directly affects the gas drainage effect in the mine.

[0003] Currently, conventional automatic drain valves for water dispensers are mostly electrically controlled, which are prone to damage and difficult to maintain. In addition, during use, it is difficult to allow sufficient water to accumulate in the tank, resulting in poor performance. It is also difficult to filter impurities in the accumulated water, causing impurities to accumulate at the bottom of the water dispenser and easily clog the drain pipe. Therefore, we have proposed an automatic drain valve device for water dispensers to solve the above problems. Utility Model Content

Example

[0017] like Figures 1-3 As shown, an embodiment of the present invention discloses an automatic water discharge valve device for a water dispenser, comprising a tank 1. A sealing cap 2 is threaded onto the upper surface of the tank 1, and an air pipe is provided on the sealing cap 2 for balancing the air pressure inside the tank 1. A water inlet pipe 3 is fixedly installed on the left side wall of the tank 1 near the upper edge. A filter screen 4, made of stainless steel, is fixedly installed on the inner wall of the tank 1 corresponding to the water inlet pipe 3. A collection mechanism 5 is fixedly installed on the left side of the tank 1 corresponding to the filter screen 4. A drain pipe 6 is fixedly installed in the middle of the lower surface of the tank 1, and a ball valve 7 is provided on the drain pipe 6. The ball valve 7 is normally open and can be closed in case of accidents, such as drainage obstruction during maintenance. A drainage mechanism 8 is fixedly installed on the lower surface of the sealing cap 2 corresponding to the upper surface of the drain pipe 6. An observation window is provided on the front side wall of the tank 1 for viewing inside the tank 1.

[0018] like Figure 2 As shown, in some embodiments, a rubber sealing ring 9 is provided between the lower surface of the sealing cap 2 and the upper surface of the tank body 1.

[0019] In this embodiment, the rubber sealing ring 9 improves the sealing effect between the lower surface of the sealing cap 2 and the upper surface of the tank body 1.

[0020] like Figure 2As shown, in some embodiments, the lower sidewall of the filter screen 4 is tilted at an angle of 45°.

[0021] In this embodiment, impurities inside the filter screen 4 can flow more effectively to the collection mechanism 5, preventing impurity accumulation.

[0022] like Figure 3 As shown, in some embodiments, the collection mechanism 5 includes a rectangular box 501, a rectangular opening 502, a mechanical seal 503, a ball screw 504, a handle 505, a ball nut 506, a rectangular sleeve 507, a sealing plate 508, and a sealing plug 509. The rectangular box 501 is fixedly installed on the left side of the tank 1. The right side wall of the rectangular box 501 and the left side wall of the tank 1 have rectangular openings 502 at positions corresponding to the lower side wall of the filter screen 4. The left side wall of the rectangular box 501 has... A ball screw 504 is installed via a mechanical seal 503. A handle 505 is fixedly installed on the left end of the ball screw 504. A ball nut 506 is provided on the ball screw 504. A rectangular sleeve 507 is fixedly installed on the outer surface of the ball nut 506. A sealing plate 508 is fixedly installed on the right side of the rectangular sleeve 507, and the sealing plate 508 is arranged in a left-right correspondence with the rectangular opening 502. A sealing plug 509 is threaded onto the lower surface of the rectangular box 501.

[0023] In this embodiment, the handle 505 drives the ball screw 504 to rotate in the mechanical seal 503. The ball screw 504 drives the ball nut 506 to move to the right, so that the ball nut 506 drives the sealing plate 508 to move to the right through the rectangular sleeve 507. The sealing plate 508 seals the rectangular opening 502. Opening the sealing plug 509 can discharge impurities in the rectangular box 501. After the impurities are discharged, the sealing plug 509 is threaded onto the lower surface of the rectangular box 501. The reverse operation resets the sealing plate 508, allowing impurities in the filter screen 4 to flow into the rectangular box 501 through the rectangular opening 502. An observation window is provided on the left side wall of the rectangular box 501 for viewing the height of impurities in the rectangular box 501.

[0024] like Figure 3 As shown, in some embodiments, the sealing plate 508 has a rectangular structure, and the front, rear and upper surfaces of the sealing plate 508 are movably fitted with the front, rear and upper inner walls of the rectangular box 501.

[0025] In this embodiment, the front, rear, and upper surfaces of the sealing plate 508 can move stably left and right along the front, rear, and upper inner walls of the rectangular box 501.

[0026] like Figure 2 As shown, in some embodiments, a conical hopper 10 is fixedly installed on the lower surface of the tank body 1.

[0027] In this embodiment, the conical bucket 10 guides water and minute impurities, enabling them to be discharged.

[0028] like Figure 2 As shown, in some embodiments, the drainage mechanism 8 includes a rubber plug 801, a column 802, a first float 803, a second float 804, a fixing rod 805, a permanent magnet 806, a guide sleeve 807, and a guide rod 808. The rubber plug 801 is movably inserted into the drainage pipe 6. The first float 803 and the second float 804 are sequentially fixedly installed on the upper surface of the rubber plug 801 via the column 802. The fixing rod 805 is fixedly installed on the lower surface of the sealing cover 2 corresponding to the second float 804. The lower surface of the fixing rod 805 and the upper surface of the second float 804 are both equipped with permanent magnets 806. The left and right sides of the first float 803 and the second float 804 are fixedly installed with guide sleeves 807. The guide sleeves 807 are movably inserted with guide rods 808, and the guide rods 808 are fixedly installed on the lower surface of the sealing cover 2.

[0029] In this embodiment, when the water in the tank 1 submerges the second float 804, the first float 803 and the second float 804 will move the rubber plug 801 upwards via the column 802. The permanent magnet 806 on the upper surface of the second float 804 and the permanent magnet 806 on the fixing rod 805 will attract each other, causing the rubber plug 801 to detach from the drain pipe 6, allowing the water in the tank 1 to drain out through the drain pipe 6. When the water level in the tank 1 is higher than the first float 803, the buoyancy of the first float 803 and the attraction of the upper permanent magnet 806 work together to prevent the rubber plug 801 from moving downwards. When the water level in the tank 1 is higher than the first float 803, the buoyancy of the first float 803 and the attraction of the upper permanent magnet 806 work together to prevent the rubber plug 801 from moving downwards. When the position is lower than the lower surface of the first float 803, it loses the upward buoyancy of the first float 803. The weight of the rubber plug 801, the column 802, the first float 803 and the second float 804 causes the lower permanent magnet 806 to separate from the upper permanent magnet 806. The rubber plug 801 is inserted into the drain pipe 6, achieving the effect of sealing the drain pipe 6. Both the first float 803 and the second float 804 move up and down along the guide rod 808 through the guide sleeve 807, achieving the effect of guiding the up and down movement of the rubber plug 801, so that the rubber plug 801 can be accurately inserted into the drain pipe 6.

[0030] like Figure 2 As shown, in some embodiments, the cross-section of the rubber plug 801 is a T-shaped structure, and the lower surface of the rubber plug 801 is a conical structure.

[0031] In this embodiment, the upper part of the rubber plug 801 is made of metal and the lower part is made of rubber. The rubber plug 801 can cover the drain pipe 6 and be inserted into the drain pipe 6 to ensure the sealing effect of the rubber plug 801 on the drain pipe 6.

[0032] During use, ball valve 7 is normally open. Water flows into tank 1 through inlet pipe 3 and is filtered by filter screen 4. The filtered impurities flow through the lower side of filter screen 4 to the rectangular opening 502 in collection mechanism 5, where they flow into rectangular box 501. When impurities need to be discharged, handle 505 drives ball screw 504 to rotate within mechanical seal 503. Ball screw 504 drives ball nut 506 to move to the right, causing ball nut 506 to move the sealing plate through rectangular sleeve 507. 508 moves to the right, and the sealing plate 508 seals the rectangular opening 502 to prevent water and gas from flowing out. Opening the sealing plug 509 allows impurities in the rectangular box 501 to be discharged. After the impurities are discharged, the sealing plug 509 is threaded onto the lower surface of the rectangular box 501. The reverse operation resets the sealing plate 508, allowing impurities in the filter screen 4 to flow into the rectangular box 501 through the rectangular opening 502. When the water level in the tank 1 is higher than the second float 804 in the drainage mechanism 8, the first float 803 and the second float 804 will pass through the column 80 2. The rubber plug 801 moves upward, and the permanent magnet 806 on the upper surface of the second float 804 attracts the permanent magnet 806 on the fixed rod 805. The rubber plug 801 detaches from the drain pipe 6, allowing the water in the tank 1 to drain out through the drain pipe 6. When the water level in the tank 1 is higher than the first float 803, the buoyancy of the first float 803 and the attraction of the upper permanent magnet 806 work together to prevent the rubber plug 801 from moving downward. When the water level in the tank 1 is lower than the lower surface of the first float 803, the first float 803 has no buoyancy and therefore loses its buoyancy. The first float 803 is lifted by buoyancy. Through the gravity of the rubber plug 801, the column 802, the first float 803, and the second float 804, the lower permanent magnet 806 is separated from the upper permanent magnet 806. The rubber plug 801 is then inserted into the drain pipe 6 to seal it. This allows for more complete water accumulation in the tank 1, simplifies the structure, facilitates future maintenance, improves sealing and drainage, and enhances the filtration of impurities in the accumulated water. This effectively prevents impurities from accumulating at the bottom of the tank 1 and ensures a tight seal.

[0033] In summary, the automatic drain valve device of this drainer, through the drainage mechanism 8, allows for more sufficient water accumulation in the tank 1, has a simpler structure, facilitates later maintenance, provides better sealing and drainage, increases the filtering effect on impurities in the accumulated water, effectively prevents impurities from accumulating at the bottom of the tank 1, and ensures sealing performance.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
