This utility model discloses a dual-servo gear metering dispensing valve, which relates to the field of dispensing machine technology. The dual-servo gear metering dispensing valve includes a back plate, on the left side of which a dispensing mechanism is located: a drive assembly, located on the left side of the back plate, providing power to a conveying assembly; a conveying assembly, located below the drive assembly, for conveying the adhesive; and a partition assembly, including a base plate fixedly installed at the bottom of the back plate. A valve body is fixedly installed on the left side of the base plate. Pressure sensors monitor the adhesive pressure at the front of the "L"-shaped pipe below the valve body and at the inlet of the gear metering pump. The monitoring data from the pressure sensor visually displays the pressure of the adhesive inside the conveying pipe. A pressure threshold is set using a microcontroller, PLC controller, or other control equipment, and compared with the monitoring data from the pressure sensor. Dispensing operation is stopped promptly when the pressure exceeds the threshold to prevent uncontrolled overflow of the adhesive due to excessive pressure.

This utility model discloses a disinfection device for fruit processing, including an ultraviolet disinfection machine. A first glass plate is arranged on both the left and right sides of the inner cavity of the ultraviolet disinfection machine. A guide plate is arranged on the front side of the first glass plate. Mounting blocks are arranged on the rear sides of opposite sides of the two first glass plates. Support plates are arranged on the front and rear sides of the top of the two first glass plates. Multiple dispensing devices are evenly distributed on opposite sides of the two first glass plates. A [missing information - likely a device name] is arranged on opposite sides of the two support plates. This utility model, through the coordinated use of the first glass plate, guide plate, mounting block, support plate, dispensing device, support column, positioning plate, and spacer, solves the problem that existing ultraviolet disinfection machines lack the function of separating and conveying fruits. During conveying, fruits may come into contact with each other, resulting in insufficient ultraviolet irradiation at the contact points, affecting the uniformity of fruit disinfection.

The utility model discloses a kind of installation tools of crankshaft rear oil seal, belong to oil seal installation technical field, comprising: crankshaft and the rear flange connected with the rear end of crankshaft;Multiple flywheel mounting holes are opened in the end of rear flange away from crankshaft, and the side of rear flange away from crankshaft is equipped with support disc by flywheel mounting hole, the center of the end of support disc away from rear flange is rotatably connected with support arm, and the outside of rear flange is equipped with oil seal ring, the utility model is stably installed in the outside of rear flange by flywheel mounting hole with support disc, subsequently by adjusting to the outside of oil seal ring to extrusion structure, then by the rotation of support arm, drive extrusion structure to rotate in the outside of oil seal ring, uniformly force extrusion is carried out to oil seal ring, so that oil seal ring is evenly stressed after installation is completed, avoid oil seal ring partial uneven stress to cause deformation and easily occur leakage, and simultaneously, the device can also be adapted to the installation of different size crankshaft rear oil seal.

This invention discloses a 635MPa grade niobium-vanadium-chromium composite reinforced high-performance steel bar and its smelting method. By controlling the chemical composition and V / N mass ratio of the steel bar within the range of 3.35 to 3.75, and employing a multi-element composite strengthening formula of niobium, vanadium, and chromium to replace the traditional single vanadium-nitrogen alloy addition mode, production costs are reduced. During the smelting process, a dedicated dry powder stirring device is used to pre-mix the microalloying reinforcing agent, achieving uniform mixing of powder components and removal of magnetic impurities. Simultaneously, a composite desulfurizing agent is introduced and a step-by-step addition process is adopted, combined with a gradient ladle bottom-blowing argon stirring system, to effectively reduce the sulfur content in the steel. The steel bar prepared by this invention has a uniform microstructure, high grain size, and excellent mechanical properties such as tensile strength, yield strength, strength-to-yield ratio, and elongation. It exhibits good product consistency, low production costs, and can stably mass-produce high-performance 635MPa grade high-strength earthquake-resistant steel bars.
