Problems solved by technology

[0003] Most of the traditional pipeline purging effect inspection devices need to disassemble the device erecting the target plate after purging once, remove the old target plate, replace the new target plate, and assemble the sealing sleeve to install the device. The whole process has many steps and cumbersome work. , Moreover, due to the existence of the insulation layer in the pipeline using steam purging, the residual heat of the pipeline lasts for a long time, and the replacement of the target plate cannot be replaced in a hot state, resulting in a prolonged construction period and an increase in construction costs

Embodiment Construction

[0030] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as Figure 1-2 , the present invention provides a pipe flushing target plate system, including two sealing sleeves 14 and a target plate bracket 12, the sealing sleeve 14 is welded on the left and right sides of the temporary pipe, and the target plate bracket 12 passes through the left side The sealing sleeve 14 , the temporary pipe 11 and the sealing sleeve 14 on the right side are fixed by the limiting pile 9 and the limiting pin 10 .

[0032] Such as Figure 3-13 As shown, the sealing sleeve 14 includes a first flange 1 , a second flange 2 , an inner cylinder 8 and an outer cylinder 6 .

[0033] Such as Figure 6-8 , the inner cylinder 8 is a hollow straight cylinder, and the bottom of the inner cylinder 8 is welded on the first flange 1 to form a first set. The bottom surface of the first flange ...

Abstract

The invention relates to a pipeline purging target plate system which comprises two sealing sleeves and a target plate bracket. The two sealing sleeves are symmetrically welded to the left side and the right side of a temporary pipe, the target plate bracket sequentially penetrates through the sealing sleeve on the left side, the temporary pipe and the sealing sleeve on the right side and is fixedthrough a limiting pin, the target plate bracket is provided with at least two target plate installation grooves, and every two adjacent target plate installation grooves are in opposite directions.Since the target plate bracket is provided with the target plate installation grooves, after steam purging is carried out on a pipeline, target plate replacement is carried out when the system is notcompletely cooled, the target plate bracket does not need to be disassembled in the replacing process, the target plate replacing steps are greatly simplified, the construction period is shortened, and operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of pipeline flushing, in particular to a pipeline flushing target plate system. Background technique [0002] In a system that requires high pipeline cleanliness, purging the pipeline is an important means and link to ensure the cleanliness of the pipeline installation. Through purging, the rust, dust, oil and other sundries in the pipeline can be removed to avoid these The sundries will endanger the safe operation of the system. For example: Boiler blowing in a power plant is to use steam with a certain pressure to purge the superheater, main steam pipes, etc., and discharge the steam carrying solid particle impurities to the atmosphere. Through this kind of purging, the oil and rust in the pipeline can be effectively reduced , dust and other solid particles, to meet the installation requirements of clean and pollution-free, to ensure a good working environment for steam turbine blades. [0003] Most of the traditi...
