[0002] At present, the unloading valve plays an irreplaceable role in the quantitative and uniform feeding of materials. The unloading valve is composed of a housing, an impeller, an impeller shaft, a sealing device and a driving device. The motor reducer combination or the motor chain drive combination drives the impeller. Rotation, the shell and the sealing device provide a sealed environment for material delivery, there is a large gap between the impeller and the shell, the pressure of the inlet and outlet of the discharge valve is equal, and it cannot play a sealing role
The sealing device of the unloading valve is generally a packing or oil seal, etc. It is difficult to ensure a complete seal during the use of the unloading valve, and even a small amount of material will overflow, seriously affecting the working environment

Embodiment Construction
[0020] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.
[0021] Such as figure 1 As shown, a fully sealed discharge valve, which includes:
[0022] Housing 1, the housing 1 has a material inlet 11 and a material outlet 12; both the material inlet 11 and the material outlet 12 can be welded with interface flanges to facilitate assembly;
[0023] Valve body 3, the valve body 3 is rotatably arranged in the housing 1, and the valve body 3 is provided with a material storage device 3-1; the spherical material storage device 3-1 on the valve body 3 ensures During the feeding process, there is no material residue.
[0024] Drive shaft 4, the valve body 3 is installed on the drive shaft 4, and the drive shaft 4 is rotatably supported on the housing 1, when the drive shaft 4 drives the valve body 3 to rotate to...

The invention discloses a full-sealed discharge valve, comprising a shell provided with a feed port and a discharge port; a valve body rotatably arranged in the shell and provided with storage devices; a drive shaft on which the valve body is installed and which is supported on the shell rotatably, when the shell is driven by the drive shaft to rotate in the shell till a certain storage device is corresponding to the feed port, materials fed from the feed port are received by the storage device; when the shell is driven by the drive shaft to rotate in the shell till the storage device is corresponding to the discharge port, the materials received by the storage device are fed into the discharge port; a bushing arranged between the valve body and the shell, a feed corresponding hole communicated with the feed port and a discharge corresponding hole communicated with the discharge port are arranged on the bushing, and the storage device is fully covered by the bushing except for the feed corresponding hole and the discharge corresponding hole in the rotating process of the shell. The full-sealed discharge valve disclosed by the invention has good sealing performance, so that the materials are uneasy to leak.
Description
technical field [0001] The invention relates to a fully sealed discharge valve. Background technique [0002] At present, the unloading valve plays an irreplaceable role in the quantitative and uniform feeding of materials. The unloading valve is composed of a housing, an impeller, an impeller shaft, a sealing device and a driving device. The motor reducer combination or the motor chain drive combination drives the impeller. Rotation, the casing and the sealing device provide a sealed environment for material transportation. There is a large gap between the impeller and the casing, and the pressure of the inlet and outlet of the discharge valve is equal, which cannot play a sealing role. The sealing device of the unloading valve is generally a packing or an oil seal, etc. It is difficult to ensure a complete seal during the use of the unloading valve, and even a small amount of material will overflow, seriously affecting the working environment.
