The utility model relates to the technical field of overflow valves, and discloses an adjusting device for an overflow valve, which comprises a pressure valve rod penetrating through the top of an overflow valve main body; the supporting seat is arranged at the top of the overflow valve main body, the top end of the supporting seat is rotationally connected with a pressure rod, and a plurality of hook grooves are formed in the pressure rod; and one end of the spring assembly is hooked on one hook groove, and the other end of the spring assembly is hooked on the anchor bolt. A novel adjusting mode is adopted, a lever structure and an external spring assembly are designed, the length of a force arm is adjusted by changing the hanging position of the spring assembly, therefore, pressure adjustment of the valve element is achieved, operation is easy, the principle is ingenious, the adjusting result can be visually reflected, and professional experience is not needed.

The present invention belongs to the technical field of oilfield development, and in particular, is a method for preparing a visualized core acidification corrosion measurement model. The technical scheme of the present invention is: select the required measurement core, and obtain two core models with the same thickness of 2-4 mm according to the design; evenly apply the prepared adhesive on both sides of the two core slices, and then bond them with two pieces of white glass with the same specifications; the two core slices are arranged oppositely, and two sections of hoses are clamped and arranged at both ends of the core slices; finally, the outer periphery of the core slice between the two pieces of glass is evenly coated with adhesive, and statically consolidated to obtain a visualized core acidification corrosion measurement model. The present invention utilizes the visibility of glass and the authenticity of the properties of the required acidified formation core, and the two are combined to highly restore the formation acidification process, so that the evaluation process is more real and visible, and the problems generated in the acidification process can be intuitively analyzed. At the same time, the present invention is simple to make, low in cost, and short in testing time, and has high practicality.

This utility model discloses a quick-release structure for a motor-driven lead screw. The structure includes a mounting base, a locking pin, and a lead screw sleeve. One end of the mounting base is fixed to the motor, and the other end is a clamp-shaped lever arm structure with a through hole. The through hole has a lateral opening and a stepped hole with a spiral involute profile on its inner wall. The locking pin includes a pin shaft body, a radially protruding locking structure, and a wrench. The locking structure mates with the stepped hole profile. The outer side of the lead screw sleeve mates with the inner plane of the clamp-shaped lever arm. By rotating the locking pin, and utilizing the locking structure's engagement with the spiral involute profile, the mounting base and the lead screw sleeve can be quickly locked and separated. This utility model offers quick assembly and disassembly, reliable structure, and is suitable for medical equipment, precision instruments, and automated equipment.
