Description

Technical Field

[0001] The utility model relates to the technical field of pressure relief valve processing, in particular to a positioning tool for pressure relief valve processing. Background Art

[0002] The pressure relief valve is a type of hydraulic control valve that ensures that the medium pressure in the equipment and pipeline is below the set pressure, protects the equipment and pipeline, and prevents accidents. During the processing of the pressure relief valve, it is necessary to punch holes on the end face of the valve body through a punching mechanism according to the design requirements. During the punching operation, the pressure relief valve needs to be positioned using a positioning tool to ensure the stability of the processing.

[0003] A patent with announcement number CN220217589U in the prior art discloses a positioning tool for pressure relief valve processing, which relates to the technical field of pressure relief valve processing, including a supporting base plate, a supporting frame is arranged on the top of the supporting base plate, and a cylinder is arranged on the top of the supporting frame, a moving component for moving the positioning component is arranged in the middle of the supporting base plate, and a positioning component for positioning the pressure relief valve to be processed is arranged on the top of the supporting base plate, thereby increasing the convenience of the device, and realizing the flipping of the positioned pressure relief valve through the arranged servo motor and rotating column, facilitating the processing of different surfaces, increasing the convenience of the use of the device, and realizing the positioning of the pressure relief valve through the arranged two groups of hydraulic cylinders, positioning soft plates and a group of positioning cylinders, thereby reducing limitations.

[0004] The device positions the pressure relief valve by positioning the soft plate. Since the surface of the pressure relief valve is mostly irregular, in order to increase the contact area, the soft plate will have a large deformation during positioning. The repeated deformation and recovery of the soft plate can easily cause the soft plate to break. When the pressure relief valve is punched, the raw material debris generated by the processing will accumulate on the pressure relief valve, causing pollution to the pressure relief valve. Therefore, a positioning tool for pressure relief valve processing is needed to meet the use requirements. Utility Model Content
