Abstract
The invention relates to a pipe welding opening detector and belongs to the technical felid of welding equipment. The pipe welding opening detector comprises an admission piece 1, a barometer 2, a sealing strip 3, a detector shell 4, a screw clamp 5, and a detector shell joint 6. The admission piece 1 and the barometer 2 are arranged on the detector shell 4. The detector shell 4 is in the shape of a semi-circle. The sealing strip 3 is arranged inside the detector shell 4. The screw clamp 5 is arranged on the outer edge of the detector shell 4. The detector shell joint 6 is used for connecting two detector shells 4. The middle of the detector shell 4 is arc-shaped. In use, two edges are respectively fixedly arranged on two pipelines which are welded together. The arc in the middle of the detector shell 4 is directed at the welding opening of the two pipelines.
Description
Technical field
The present invention relates to technical field of welding equipment, is a kind of pipeline welding mouth detecting device.
Background technology
The present invention is during mainly for pipeline welding, and whether fully for the welding of the part of needs welding, the difficulty that some little cracks can't be detected is invented a kind of pipeline welding mouth detecting device.
Summary of the invention
The present invention is a kind of a kind of pipeline welding mouth detecting device that utilizes air detection pipeline welding mouth whether to have the crack, can address the above problem.
The present invention is by admission piece, rain glass, and sealing strip, detector housing, screw checkpost, the detector housing junction forms.Admission piece and rain glass are arranged on detector housing, the detector housing semicircular in shape, and sealing strip is arranged on the detector housing inboard, and screw checkpost is arranged on the outer of detector housing, and the detector housing junction is used for connecting two detector housings.Curved in the middle of detector housing, during use, both sides are fixedly mounted on respectively on two pipelines that weld together, and the detector housing medial arc is aimed at two pipeline soldering opening places.
When the present invention uses, detector housing both sides are fixedly mounted on two pipelines that weld together with screw checkpost respectively, the detector housing medial arc is aimed at two pipeline soldering opening places, be filled with air from admission piece, observe air pressure by rain glass and whether descend, if air pressure descension theory open conduit weld has the crack.
Detector housing of the present invention has two, and semicircular in shape just becomes a circle altogether, is coupled together by the detector housing junction.When detecting, screw checkpost is used for fixing two detector housings.When detecting, sealing strip is used for the gap of seal detector shell and pipeline junction.
