Nitrogen transmitting pipeline leakage detecting and temporary leakage-blocking device

Abstract

The invention relates to the technical field of nitrogen transmission, in particular to a nitrogen transmitting pipeline leakage detecting and temporary leakage-blocking device. The nitrogen transmitting pipeline leakage detecting and temporary leakage-blocking device comprises two semi-circular pipes; semi-circular rings are disposed at the two ends of the semi-circular pipes correspondingly; lenses are embedded into the semi-circular pipes correspondingly; first sliding grooves are formed in the outer walls of the semi-circular pipes correspondingly; the directions of the first sliding grooves are the same as those of long shafts of the semi-circular pipes; one ends of magnetic blocks are inserted into the first sliding grooves; second sliding grooves are formed in the inner walls of thesemi-circular pipes correspondingly; the second sliding grooves are parallel to the first sliding grooves; one ends of iron blocks are inserted into the second sliding grooves; and the iron blocks are matched and connected with the magnetic blocks. The device is convenient and simple in operation process, the leakage detecting efficiency can be effectively improved, and after detection is finished and when the device is not dismounted, the device can serve as a temporary leakage-blocking device.

Description

technical field [0001] The invention relates to the technical field of nitrogen gas transportation, in particular to a gas leakage detection and temporary plugging device for nitrogen gas transportation pipelines. Background technique [0002] Nitrogen, chemical formula N 2 , It is a colorless and odorless gas under normal conditions, and generally nitrogen is less dense than air, nitrogen accounts for 78.08% (volume fraction) of the total atmosphere, and is the main component of air. Nitrogen is generally used as a protective gas in industrial production . During the use of nitrogen, it is generally transported through pipelines. Long-term use of pipelines will lead to air leakage in the pipeline. In order to find out the leak point, the traditional method is to manually smear soapy water on the pipeline and then observe it. This method of smearing is inefficient, which in turn leads to slow air leak detection. Contents of the invention [0003] The purpose of the pres...
