A kind of pipe-line non-stop plugging special device that do not stop production, comprise urceolus (1), in described urceolus (1), be provided with push rod (2), the bottom of described push rod (2) is provided with taper stopper (3), urceolus (1) is stretched out at described push rod (2) top, described urceolus (1) top is provided with sealing cover (8), described push rod (2) is through sealing cover (8) center, described push rod (2) top is provided with press rods (7), described press rods (7) is controlled push rod (2) and is moved up and down vertically, described push rod (2) inside is provided with secondary push rod (4), described secondary push rod (4) bottom is provided with taper stopper B (5), push rod (2) top is stretched out at described secondary push rod (4) top, described secondary push rod (4) top is provided with swingle (6), on described secondary push rod (4) outer tube wall and push rod (2) inner tube wall be provided with the screw thread (9) of coupling, described swingle (6) rotation is controlled secondary push rod (4) and is moved up and down vertically, described secondary push rod (4) advances downwards, described taper stopper B (5) embeds taper stopper (3) inside, described urceolus (1) middle part is connected with relief pipeline, and described relief pipeline is provided with pressure test table (11), and the relief pipeline of described pressure test table (11) outer end is provided with pressure relief valve (12).
Described taper stopper B (5) the widest position diameter is 1/4th of taper stopper (3) the widest position diameter.
Described secondary push rod (4) is hollow circular ring with taper stopper (3) joint, and described middle vacancy diameter is greater than taper stopper B (5) the widest position diameter.
Described urceolus (1) bottom outside be provided with Stamping Steel Ribbon (13).
The beneficial effect of model utility: this equipment is directly installed on ball valve while using; By stopper shutoff, steal hole, secondary stopper is further reinforced shutoff, good airproof performance; This device structure is simple, be easy to disassembly and assembly transportation, use safe, easy.Be applicable to various media in stopping transportation not, not step-down, guarantees, in the situation of the normal operation of pipeline, to rush to repair, and the construction operations such as maintenance, are widely used in oil, in the pipeline construction of coal gas.
