The invention discloses a positioning tool for installing and welding of a nozzle pipe and an elbow in a venturi scrubber device. The positioning tool comprises a first flange cover connected with a nozzle pipe connecting flange and a second flange cover connected with an elbow connecting flange. A first flange cover hole and a second flange cover hole are formed in the center of the first flange cover and the center of the second flange cover respectively. The two ends of a core bar penetrate the first flange cover hole and the second flange cover hole respectively, and it can be guaranteed that the assembling tolerance of the nozzle pipe and the axis of a connecting port in the upper portion of the 90-degree elbow is 1 mm through the matching clearances at the matched connecting positions of the two ends of the core bar, the first flange cover hole and the second flange cover hole. After the positioning tool for installing and welding of the nozzle pipe and the elbow in the venturi scrubber device is used, it can be guaranteed that the assembling tolerance of the nozzle pipe and the axis of the connecting port in the upper portion of the 90-degree elbow is 1 mm.
Description
technical field [0001] The invention relates to a positioning tool used when welding a nozzle pipe and an elbow in Venturi scrubber equipment. Background technique [0002] Venturi scrubber equipment is a hydraulic dust collector, which includes a part that is fixedly connected by a 90° elbow, a nozzle pipe and a diffuser pipe. The specific connection structure is: the upper connection port of the 90° elbow and An elbow connection flange is respectively arranged on the lower connection port, and the diffusion pipe connection flange at one end of the diffusion pipe is connected with the elbow connection flange on the upper connection port of the 90° elbow, so that the diffusion pipe and the 90° elbow Fixed connection, and the central axis of the diffuser coincides with the central axis of the upper connection port of the 90° elbow, a side wall hole is provided on the side wall of the 90° elbow facing the diffuser, and the outer connection of the nozzle tube The end of the no...
