[0002] Rotary feed valves are specialized equipment used in powder (powder, granular materials, powder-granule mixtures) conveying systems for unloading, metering, dust removal, quantitative conveying, mixing, and packaging.

[0003] In the existing technology, some pneumatic equipment, such as gripper chucks, are driven by cylinders. In order to ensure that the rotation can be used, a rotary valve is used to supply air. However, some rotary valves are prone to air leakage after a period of use. Therefore, a new type of rotary valve for double-sealed chucks is needed to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide a novel rotary valve for double-sealed chucks, in order to solve the problem mentioned in the background art, where gripper chucks are driven by cylinders, and rotary valves are used to supply air in order to ensure rotation. However, some rotary valves are prone to air leakage after a period of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel double-sealed chuck-specific rotary valve, comprising a rotary valve core, a rotary valve housing movably sleeved on the outer side of the rotary valve core, a fixed mounting base fixedly installed at one end of the rotary valve housing, an air inlet 1, an air inlet 2, and an air inlet 3 fixedly installed on the rotary valve housing, an annular air passage 1, annular air passage 2, and annular air passage 3 being opened in the inner arm of the rotary valve housing, and an air supply nozzle 2, an air supply nozzle 3, and an air supply nozzle 1 arranged on one side of the rotary valve core, with air inlet 1 connected to annular air passage 1, air inlet 2 connected to annular air passage 2, and air inlet 3 connected to annular air passage 3.

[0006] Preferably, the rotary valve core is provided with a first conveying air passage, a second conveying air passage, and a third conveying air passage. The first conveying air passage connects the first annular air passage and the first air nozzle. The second conveying air passage connects the second annular air passage and the second air nozzle. The third conveying air passage connects the third annular air passage and the third air nozzle.

[0007] Preferably, a first rotary bearing and a second rotary bearing are arranged between the rotary valve core and the rotary valve housing, and the fixed ends of the first rotary bearing and the second rotary bearing are respectively connected to the rotary valve core and the rotary valve housing.

[0009] Preferably, a rotating mounting base is fixedly installed at one end of the rotary valve core.

[0010] The beneficial effects of this utility model are:

[0011] This invention utilizes a rotary valve core and a rotary valve housing in cooperation. Air is supplied to the rotary valve housing through inlet nozzles 1, 2, and 3, which are fixed in place. The gas is then transmitted within the rotary valve core through internal annular air passages 1, 2, and 3, thus delivering gas to the rotating ports of outlet nozzles 1, 2, and 3. This ensures stable gas delivery. Furthermore, multiple sealing rings are used for sealing, preventing gas from interfering with each other or leaking in different channels. This further ensures the stability of the gas supply, provides better sealing, maintains pressure for a longer time, and extends the service life. Attached Figure Description
