Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly tools, in particular to a disassembly and assembly tool for a gas pressure regulator. Background Art

[0002] There are a large number of pressure regulators distributed in the gas transmission and distribution system, which are responsible for regulating the pressure from high pressure to low pressure. The operating and management units need to regularly inspect and maintain the pressure regulators to ensure the safe and stable operation of the gas pipeline network and the normal gas supply. The stroke indicator is an important part of the pressure regulator. When the stroke indicator fails, it needs to be repaired or replaced. The stroke indicator is mainly composed of a stroke pointer, a threaded column and a locking nut. It is screwed onto the pressure regulator through the threaded column and locked and fixed by the locking nut. Because its stroke pointer is in the center of the threaded column and extends out, it makes the disassembly and assembly operation difficult, resulting in low disassembly and assembly efficiency, and there are currently no special tools in the field for disassembling and assembling such stroke indicators.

[0003] In the patent document with the publication number CN207971877U, a tool for quick disassembly and assembly of hexagon socket bolts for the rear flange of a gas pressure regulator is disclosed. The device is provided with a handle, an adapter sleeve and a plurality of hexagonal prism clamps of different lengths, so that one end of the adapter sleeve is vertically connected to one end of the handle through a ratchet structure, and a hexagonal groove is provided at the other end of the adapter sleeve along the central axis. Thus, a tool for quick disassembly and assembly of hexagon socket bolts for the rear flange of a gas pressure regulator is formed, which has a simple structure, low cost, convenient use and strong adaptability. When disassembling and assembling the hexagon socket bolts of the rear flange of the gas pressure regulator, a hexagonal prism clamp of suitable length is selected according to the operating space and the distribution of the hexagon socket bolts, one end of the hexagonal prism clamp is placed in the hexagonal groove of the adapter sleeve, and the other end of the hexagonal prism clamp is placed in the hexagonal groove of the hexagon socket bolt, and the hexagon socket bolt can be quickly disassembled and assembled by rotating the handle. The utility model improves adaptability to operating space and work efficiency by connecting the adapter sleeve and the handle through a ratchet structure and arranging a plurality of hexagonal column clamps with different lengths.
