BLOCKING DEVICE FOR TESTING AIRTIGHT OF PIPE

摘要

The present invention relates to a blocking device for testing the airtightness of a pipe, mounted on an end part of the pipe to block the pipe, thereby checking for leakage of the pipe. The blocking device for testing the airtightness of a pipe comprises: a housing (110); pressing plate (120); and elevation and descent control bolt (122). The housing (110) has a space part formed inside and has an open front surface. The pressing plate (120) is horizontally inserted into the housing (110). The elevation and descent control bolt (122) is vertically coupled to the housing (110) to pass through an upper surface of the housing (110) and has a lower part coupled to an upper surface of the pressing plate (120) to move the pressing plate (120) upward and downward depending on rotation in a clockwise or counterclockwise direction. A concave part (111) with an inwardly shaped concavity is formed on the front surface of the lower plate (114) forming the lower surface of the housing (110). The blocking device for testing the airtightness of the pipe is mounted on the end part of the pipe such that the work time taken to block the end part of the pipe can be reduced, thereby remarkably increasing work efficiency.
