Abstract

The invention discloses a detecting device for special equipment in construction engineering. The detecting device comprises to-be-detected special equipment needing airtightness detection and a standard device for comparison with the to-be-detected special equipment. A differential pressure pipeline is connected between the special equipment and the standard device and a differential pressure detector is installed at the differential pressure pipeline. A first L-shaped pneumatic pipe is communicated inside the special equipment; a second L-shaped pneumatic pipe is communicated inside the standard device; and the first L-shaped pneumatic pipe and the second L-shaped pneumatic pipe are communicated with a pneumatic pipe. A first electromagnetic regulating valve is installed at the first L-shaped pneumatic pipe; a second electromagnetic regulating valve is arranged at the second L-shaped pneumatic pipe; a third electromagnetic regulating valve is installed at the pneumatic pipe; and an air pump is connected to the pneumatic pipe.

Description

technical field [0001] The invention relates to the technical field of special equipment detection, in particular to a special equipment detection device for construction engineering. Background technique [0002] Special equipment refers to boilers, pressure vessels (including gas cylinders, the same below), pressure pipelines, elevators, hoisting machinery, passenger ropeways, large amusement facilities and special motor vehicles in the field (factory) that involve life safety and are relatively dangerous. . Among them, boilers, pressure vessels (including gas cylinders), and pressure pipelines are pressure-bearing special equipment; elevators, hoisting machinery, passenger ropeways, and large-scale amusement facilities are electromechanical special equipment. [0003] At present, the air tightness detection method of special equipment mainly includes water detection method: it is to flush the special equipment to be tested into compressed air and seal it, then immerse it...
