The application discloses a servo cut-off valve group, which comprises a first valve body and a second valve body integrated on a valve seat. Both the valve bodies are provided with valve cavities, and the valve cavities are internally provided with valve spools driven by a servo motor through a screw rod. The valve bodies are provided with outer ring channels communicated with inlet and outlet of the valve seat on the side surfaces, the outer ring channels are communicated with the valve cavities through a plurality of uniformly distributed lateral flow channels, and the inner walls of the valve cavities are further provided with inner ring channels. The longitudinal flow channels at the bottoms of the two valve cavities are communicated with each other through channels in the valve seat. When the two valve spools synchronously rise above the lateral flow channels, fluid can sequentially pass through the flow channels, and the valve is opened; when the two valve spools synchronously descend to completely cover the lateral flow channels, the valve is closed. The two valve cavities are communicated at the bottoms to form a pressure balance cavity, so that the valve spools are hardly subjected to axial thrust when the valve is closed, and high pressure is converted into sealing force in the radial direction of the valve spools, thereby fundamentally solving the high pressure leakage problem of traditional cut-off valves, and the application is especially suitable for high pressure equipment such as filter presses.

This utility model discloses a conveying device for producing lactic acid bacteria beverages, including a conveyor frame. A conveying mechanism is installed at the upper center of the conveyor frame. A guide adjustment mechanism is installed on both sides of the conveying mechanism on the conveyor frame. The guide adjustment mechanism includes mounting plates symmetrically installed at the middle of the two side walls of the conveyor frame and a bidirectional lead screw installed between the two mounting plates. The advantages are: by installing the guide adjustment mechanism on the conveyor frame, this utility model enables the lactic acid bacteria beverage conveying device to not only adjust the spacing between the serpentine guide plates as needed under the action of the motor, the bidirectional lead screw, and the linkage rod, thus meeting the convenient conveying needs of lactic acid bacteria beverages of different sizes after filling, but also effectively increase the conveying capacity of the filled lactic acid bacteria beverages on the device under the action of the serpentine guide plates, meeting the high-efficiency conveying needs of large-volume filled lactic acid bacteria beverages.
