Description

Technical Field

[0001] This application relates to the field of packaging equipment technology, specifically to a discharge valve and a ton container having the same. Background Technology

[0002] IBCs are medium-sized bulk containers, typically made of resin, and are widely used in the chemical, food, and pharmaceutical industries for storing and transporting liquid materials. The valves on IBCs are key components used to control the discharge and filling of materials.

[0003] Existing valves use a simple ball valve structure, where the valve opening is adjusted by rotating the ball valve core. However, the above structure makes it difficult to precisely control the valve opening, and a small twist often leads to a sudden change in flow. Therefore, it is necessary to design a discharge valve that can quickly open and close and precisely adjust the opening size, as well as a ton container equipped with this discharge valve. Utility Model Content

[0004] A discharge valve is disposed on the lower side of a ton container, including a fixed valve body, a rotating valve core, and an adjusting device; The fixed valve housing includes a cylindrical base arranged laterally, a cylindrical valve cavity partially located on the cylindrical base, a valve housing inlet located on the right side of the cylindrical valve cavity, a valve housing outlet located below the cylindrical valve cavity, an adjusting cavity located on the left half of the cylindrical base, a worm gear through hole located above the adjusting cavity, a connecting inlet located on the right side of the adjusting cavity and connected to the cylindrical valve cavity, and a connecting outlet located on the left side of the adjusting cavity. The rotating valve core is rotatably disposed within the fixed valve housing, including a valve core cylinder that rotates with the cylindrical valve cavity and is open at the right end, a valve core outlet disposed at the lower end of the valve core cylinder and aligned with the valve housing outlet, and an adjusting central shaft disposed on the left side of the valve core cylinder. The adjusting central shaft passes sequentially through the connecting inlet, the adjusting cavity, and the connecting outlet. The adjusting central shaft has an annular groove cut into it, and fixed locking teeth are evenly distributed circumferentially on the left side of the annular groove.

[0005] The regulating device includes: The input component includes a rotatable active worm gear disposed in the worm gear through hole and a rotatable annular worm wheel disposed in the adjustment cavity. The annular worm wheel meshes with the active worm gear, and the inner wall of the annular worm wheel is provided with an anti-rotation insertion hole along the axial direction. The transmission assembly includes an adjusting collar sleeved on the adjusting shaft, an annular protrusion formed on the inner wall of the adjusting collar and cooperating with the annular groove on the shaft, transmission locking teeth that cooperate with the fixed locking teeth are evenly distributed on the left side of the annular protrusion, an anti-rotation key that meshes with the anti-rotation insertion hole is provided on the side of the adjusting collar, and a compression spring is also provided on the right side of the adjusting collar.

[0006] The right side of the adjusting collar is also provided with a receiving ring groove for accommodating the compression spring.

[0007] The worm gear through hole extends through the cylindrical foundation in the front-to-back direction.

[0008] One end of the active worm gear is exposed outside the worm gear through hole.

[0009] The case also discloses a ton container equipped with the aforementioned discharge valve.

[0010] The discharge valve described in this utility model has the following beneficial effects: The discharge valve described in this case can quickly achieve full opening and full closing of the valve body, and is suitable for rapid material unloading conditions. By rotating the adjusting shaft, valve core cylinder, and valve core outlet, and adjusting the overlap between the valve core outlet and the valve body outlet, the valve body opening can be quickly adjusted.

[0011] The discharge valve described in this case can also achieve precise adjustment of the valve body opening through an adjustment device, making it suitable for working conditions requiring precise quantitative discharge. Rotating the active worm gear drives the annular worm wheel and the anti-rotation socket to rotate; the anti-rotation socket acts on the anti-rotation key, thereby driving the adjusting collar, the annular flange, and the transmission locking teeth to rotate; the transmission locking teeth act on the fixed locking teeth, thereby driving the rotating valve core to rotate precisely, thus achieving precise adjustment of the valve body opening.

The rotating valve core 2 is rotatably disposed within the fixed valve housing 1, including a valve core cylinder 21 that rotates with the cylindrical valve cavity 12 and is open at the right end, a valve core outlet 22 disposed at the lower end of the valve core cylinder 21 and aligned with the valve housing outlet 14, and an adjusting central shaft 23 disposed on the left side of the valve core cylinder 21. The adjusting central shaft 23 passes sequentially through the connecting inlet 17, the adjusting cavity 15, and the connecting outlet 18. The adjusting central shaft 23 has an annular groove 24 cut into it, and fixed locking teeth 25 are evenly distributed circumferentially on the left side of the annular groove 24.

The annular worm wheel 312 meshes with the active worm 311, and the inner wall of the annular worm wheel 312 is provided with an anti-rotation insertion hole 313 along the axial direction. The transmission assembly 32 includes an adjusting collar 321 sleeved on the adjusting shaft 23, an annular protrusion 322 formed on the inner wall of the adjusting collar 321 and cooperating with the annular groove 24 on the shaft, transmission locking teeth 323 that cooperate with the fixed locking teeth 25 are evenly distributed on the left side of the annular protrusion 322, and an anti-rotation key 324 that meshes with the anti-rotation insertion hole 313 is provided on the side of the adjusting collar 321, and a compression spring 325 is also provided on the right side of the adjusting collar 321.

[0022] The right side of the adjusting collar 321 is also provided with a receiving ring groove 326 for accommodating the compression spring 325.
