This application discloses a drain valve, relating to the field of drain valves, including a valve body. An inlet pipe is fixedly connected to one side of the valve body, and a drain pipe is fixedly connected to the bottom of the valve body. A first connecting ring is fixedly connected to the middle of the other side of the valve body. A miniature hydraulic telescopic rod is fixed inside the first connecting ring. A connecting rod is fixed to the power output end of the miniature hydraulic telescopic rod, and a baffle is fixed to one end of the connecting rod. This device connects two connecting holes to an external hydraulic device. The remote hydraulic device controls the movement of the connecting rod, thereby controlling the position of the baffle. When the connecting rod is extended to its maximum length, the baffle can abut against one end of the inlet pipe, sealing against leakage during use. Simultaneously, the baffle can completely cover one end of the inlet pipe, preventing further water flow from the drain pipe. When the baffle retracts, water from the inlet pipe can be discharged from the drain pipe, thus achieving remote control at a low cost.

This disclosure relates to the field of prefabricated cabin connection technology. Embodiments of this disclosure provide a non-metallic high-strength fiber fireproof board prefabricated cabin connection structure, including a prefabricated cabin. A cabin door is rotatably connected to the front side of the prefabricated cabin, and a base plate is fixedly connected to the bottom of the prefabricated cabin. In this utility model, through the cooperation of components such as the frame of the fireproof board installation mechanism, the miniature hydraulic cylinder, and the arc-shaped fixing plate, when it is necessary to install the fireproof board on the outer surface of the prefabricated cabin, the worker first positions the fireproof board through the positioning holes, and then pushes the fireproof board forcefully. During the extension of the hydraulic rod, the arc-shaped rotating rod is pushed, causing the arc-shaped fixing plate to rotate through the support column. The rotation of the support column allows the arc-shaped fixing plate to install the positioned fireproof board. This technical solution solves the technical problem of unstable installation of fireproof boards in related technologies.

This utility model relates to the field of lubricating oil processing, and more particularly to a lubricating oil processing and conveying system, including a main pipeline, branch pipelines, an energy metering chip, a controller, and a power management module. A flow quality sensor is installed on the main pipeline to monitor the lubricating oil flowing through it. Branch pipelines branch off from the main pipeline and are equipped with a proportional solenoid valve and a miniature hydraulic generator turbine. The proportional solenoid valve adjusts its opening degree according to a control signal. The miniature hydraulic generator turbine, located inside the branch pipeline, rotates and generates electricity as the lubricating oil flows through it. The controller is connected to the flow quality sensor, the proportional solenoid valve, and the miniature hydraulic generator turbine, respectively, receiving signals from the flow quality sensor and controlling the opening degree of the solenoid valve. The energy metering chip monitors the power generation of the miniature hydraulic generator turbine. This utility model enables simple and accurate flow monitoring and control, has the ability to detect pipeline blockages, and reduces the need for external power supply.
