Technical Field

[0001] This utility model belongs to the field of discharge valve technology, and in particular relates to a wear-resistant discharge valve with alternating opening and closing of dual valve plates. Background Technology

[0002] A discharge valve is a valve device specifically designed to control the discharge of materials (solid particles, powders, slurries, etc.) from containers or pipelines. Its core function is to ensure the smooth transport of materials while achieving precise switching between "opening for discharge" and "closing for interception". It can also adapt to the physical properties (such as hardness, corrosiveness, and fluidity) and working conditions (such as high temperature, high pressure, and dusty environments) of different materials.

[0003] Chinese patent discloses a pneumatic feed and discharge valve, publication number CN211117629U. The patent describes a valve comprising: "a housing, an end cap on the top of the housing that mates with the upper end of the housing, and the end cap and housing are fixedly connected by bolts; a cylinder on the top of the end cap, with a pull rod fixedly mounted on the movable end of the cylinder, the pull rod located inside the housing; and a block at the lower end of the housing. This utility model has a reasonable structural design, is easy to use, has good sealing effect, reduces friction between the end cap and the valve core, extends service life, has better wear resistance, is less prone to damage, has low cost, and facilitates feeding and discharging."

[0004] However, in the above solution, when the valve is in use, the valve stem will rub against the valve body when frequently controlling the opening and closing of the valve, and a lot of residual material will remain on the inner wall of the valve during discharge. Therefore, it is necessary to design a wear-resistant discharge valve with alternating opening and closing of dual valve plates. Utility Model Content

The discharge assembly 9 can be used to realize alternating opening and closing, and to realize orderly feeding operation.

[0020] In this embodiment, after the device finishes discharging material through the discharge assembly 9, the drive motor 4 can be turned on to control the screw 5 to rotate. When the screw 5 rotates, it will control the vertical rod 7 and the moving plate 6 to move horizontally downward. At this time, the scraper ring 8 will also descend horizontally and scrape the inner wall of the discharge pipe 2, scraping off the material remaining on the inner wall of the discharge pipe 2. The scraper ring 8 is made of rubber, so it will not damage the inner wall of the discharge pipe 2 when it scrapes.

[0021] In a further preferred embodiment of this utility model, the feed pipe 1 and the discharge pipe 2 are Y-shaped structures, with the discharge pipe 2 arranged vertically downwards.

[0022] In this embodiment, the discharge pipe 2 is set vertically downwards to facilitate the discharge of materials from inside the discharge pipe 2 and avoid the problem of material blockage.

[0023] In a further preferred embodiment of this invention, the vertical rod 7 is arranged perpendicularly to the discharge pipe 2, and the vertical rod 7 is tightly fitted to the top of the discharge pipe 2. In this embodiment, the drive motor 4 is turned on to control the screw 5 to rotate. When the screw 5 rotates, it will control the vertical rod 7 and the moving plate 6 to move horizontally downward. At this time, the scraper ring 8 will also descend horizontally.

[0024] In a further preferred embodiment of this utility model, the center of the moving plate 6 and the discharge pipe 2 are located at the same point, and the scraper ring 8 forms a lifting structure through the screw 5.

[0025] In this embodiment, the scraper ring 8 scrapes the inner wall of the discharge pipe 2, scraping off the material remaining on the inner wall of the discharge pipe 2.

[0026] In a further preferred embodiment of this utility model, the scraper ring 8 is tightly fitted to the inner wall of the discharge pipe 2, and the scraper ring 8 is made of soft rubber.

[0027] In this embodiment, the scraper ring 8 is made of rubber, so it will not damage the inner wall of the discharge pipe 2 when it scrapes.

[0028] Example 2 Based on Embodiment 1, a preferred embodiment of the wear-resistant discharge valve with alternating opening and closing of dual valve plates provided by this utility model is, for example... Figures 1 to 5As shown: The discharge assembly 9 includes: a first discharge motor 903 fixedly connected to the surface of the feed pipe 1, a second discharge motor 912 fixedly connected to the surface of the discharge pipe 2, valve stems 904 fixedly connected to the output ends of the first discharge motor 903 and the second discharge motor 912, valves 906 fixedly connected to one end of the two sets of valve stems 904, a first buffer pad 907 fixedly connected to the side of the two sets of valves 906, a second buffer pad 908 fixedly connected inside the feed pipe 1 and the discharge pipe 2, bushings 905 fixedly connected inside the feed pipe 1 and the discharge pipe 2, retaining rings 911 fitted inside the two sets of bushings 905 and fixedly connected to the two sets of valve stems 904, oil holes 910 provided inside the two sets of bushings 905, a linkage controller 909 fixedly connected to one side of the first discharge motor 903 and the second discharge motor 912, a mounting plate 901 fixedly connected to the surface of the discharge pipe 2, and a material level sensor 902 fixedly connected to one side of the mounting plate 901.

[0029] In this embodiment, by setting a material level sensor 902, when the material level sensor 902 does not detect material, it sends a message to the linkage controller 909 on the first discharge motor 903, causing the first discharge motor 903 to work and drive the valve stem 904 to rotate. The valve stem 904 then drives the valve 906 inside the feed pipe 1 to rotate, opening the feed pipe 1 and allowing material to enter the feed pipe 1 and then enter the discharge pipe 2 for storage. When the material level sensor 902 detects material, it controls the first discharge motor 903 to close the valve 906 inside the feed pipe 1 through the linkage controller 909, stopping the feeding, and sends a signal to the linkage controller 909 on the second discharge motor 912, causing the valve 906 of the discharge pipe 2 to open and discharge the stored material, thus achieving the purpose of quantitative feeding. Under the effect of the oil hole 910, lubricating oil can be periodically injected into the connection between the bushing 905 and the valve stem 904 through the oil hole 910, which plays a lubricating role.

[0030] In a further preferred embodiment of this utility model, a vertical transparent plate is provided on the surface of the discharge pipe 2, and the material level sensor 902 is electrically connected to two sets of linkage controllers 909.

[0031] In this embodiment, by setting a material level sensor 902, two sets of linkage controllers 909 can be controlled to control two sets of valves 906 to open and close alternately.

[0033] In this embodiment, the first buffer pad 907 and the second buffer pad 908 can effectively reduce the friction between the valve 906 and the feed pipe 1 and the discharge pipe 2 when the valve is opened and closed.

[0034] In a further preferred embodiment of this utility model, both sets of oil holes 910 are inclined.

[0035] In this embodiment, lubricating oil can be periodically injected through the oil hole 910 to the connection between the bushing 905 and the valve stem 904 to achieve a lubrication effect.

[0036] In summary, the scraper ring 8 can be controlled to descend horizontally by the drive motor 4, and scraped off the material adhering to it by scraping the inner wall of the discharge pipe 2 through the scraper 8. At the same time, by setting the discharge assembly 8, the two sets of valves 906 can be controlled to open and close alternately to achieve the purpose of orderly discharge.
