Description

Technical Field

[0001] The utility model relates to the technical field of rod valves, in particular to a rod valve leakage prevention device. Background Art

[0002] The rod valve is a new type of valve developed based on the conveying control and feeding of small and medium-sized solid and block materials in the building materials, mining, metallurgy and other industries. This valve can adjust the feeding area to meet the process requirements by controlling the number of rods. The rod valve has a simple structure, is easy to operate, and has no jamming. It overcomes the shortcomings of the flat gate valve, which has a large opening and closing force due to large material particles and can even be difficult to close.

[0003] Although the rod valve in the prior art has the advantages of being easy to operate and being able to adapt to different material discharge areas according to the number of rods pulled out, it is inevitable that there are still some shortcomings in the actual use process. For example, the rod valve lacks a leak-proof mechanism, so that during the use of the rod valve, the gap between the rods is too large, resulting in leakage of fine materials, and the stretching movement of the number of rods lacks a centralized control adjustable mechanism, which makes it inconvenient to pull multiple rods. In order to avoid such problems, a rod valve leak-proof device is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a rod valve anti-leakage device, which solves the problem that the rod valve lacks an anti-leakage mechanism, resulting in leakage of fine materials due to excessive gaps between the rods during use, and the problem that the stretching movement of the number of rods lacks a centralized control adjustable mechanism, resulting in inconvenience in pulling multiple rods.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a rod valve leakage prevention device, including a valve frame and a rod, the rods are slidably arranged on both sides of the valve frame, and a plurality of rods are arranged on one side of the rod, the front and rear sides of the rod are fixedly connected with baffles, both sides of the valve frame are slidably arranged with movable frames, one side of the movable frame is equidistantly provided with a plurality of first internal thread grooves, one side of the rod is provided with a second internal thread groove used in conjunction with the first internal thread groove, and fastening bolts are threadedly connected between adjacent second internal thread grooves and first internal thread grooves.

[0006] Preferably, a threaded sleeve is fixedly connected to the bottom of the movable frame, and threaded rods threadably matched with the threaded sleeve are rotatably connected to both sides of the valve frame through bearings.

[0007] Preferably, both sides of the front and rear sides of the valve frame are provided with slide grooves, the interior of the slide grooves is slidably connected with sliders, and the opposite sides of the two sliders on the same side are fixedly connected to the front and rear sides of the inner cavity of the movable frame respectively.

[0008] Preferably, both sides of the valve frame are provided with a plurality of through grooves slidably matched with the rods.

[0009] Preferably, one end of the threaded rod is fixedly connected to a handwheel.

[0010] Preferably, the front side and the rear side of the inner cavity of the valve frame are both fixedly connected with misalignment compensation inclined plates.

[0011] Beneficial Effects

[0012] The utility model provides a rod valve anti-leakage device. Compared with the existing technology, the utility model has the following beneficial effects: the utility model blocks the gap between the rods by fixing baffles on the front and rear sides of the rods so that the baffles can pass between the adjacent rods, thereby preventing the problem of fine materials leaking easily due to the large gap between the rods. Secondly, by setting a fastening bolt, a first internal thread groove and a second internal thread groove between the movable frame and the rods, the movable frame can conveniently control the number of rods, so that the number of rods can be conveniently adjusted manually later, and the stretching movement of the rods can be collectively controlled.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figure 1-4The utility model provides a technical solution: a rod valve leakage prevention device, including a valve frame 1 and a rod 2, the rod 2 is slidably arranged on both sides of the valve frame 1, and a plurality of rods 2 are arranged on one side, and a plurality of through grooves 12 slidably matched with the rod 2 are opened on both sides of the valve frame 1, and the front and rear sides of the inner cavity of the valve frame 1 are fixedly connected with misalignment compensation inclined plates 14.

[0020] Furthermore, in order to prevent leakage between the rods 2, the front and rear sides of the rods 2 are fixedly connected with baffles 3;

[0021] Furthermore, in order to facilitate the centralized control of the rod 2, movable frames 4 are slidably arranged on both sides of the valve frame 1, and a plurality of first internal thread grooves 5 are equidistantly provided on one side of the movable frame 4. A second internal thread groove 6 used in conjunction with the first internal thread groove 5 is provided on one side of the rod 2, and fastening bolts 7 are threadedly connected between adjacent second internal thread grooves 6 and first internal thread grooves 5. Slide grooves 10 are provided on both sides of the front and rear sides of the valve frame 1, and sliders 11 are slidably connected inside the slide grooves 10. The opposite sides of the two sliders 11 on the same side are fixedly connected to the front and rear sides of the inner cavity of the movable frame 4, respectively.

[0022] Among them, in order to facilitate the driving of the movable frame 4 to centrally control the rod 2, a threaded sleeve 8 is fixedly connected to the bottom of the movable frame 4, and threaded rods 9 threadedly matched with the threaded sleeve 8 are rotatably connected to both sides of the valve frame 1 through bearings, and one end of the threaded rod 9 is fixedly connected to a handwheel 13.
