Working principle:
referring to fig. 1 to 3, the present device is assembled as shown in fig. 1;
when the device is used, firstly, a flange plate at the joint of a natural gas pipeline is positioned in a detection cylinder formed by an upper cover body 101 and a lower cover body 201, then a limiting arm 209 pushes a connecting sliding body 208 upwards, the top of the connecting sliding body 208 is positioned in a positioning groove, and then a fixing bolt 119 is rotated, so that the fixing bolt 119 is in threaded connection with the connecting sliding body 208 until the fixing bolt 119 cannot rotate; then, the two extrusion bolts 120 are rotated, the extrusion bolts 120 penetrate through the second connecting rotating plate 117 and the second positioning rotating plate 206, and the limiting arms 209 are extruded, so that the connecting sliding body 208 is further fixed;
then starting the air extracting pump 112, opening the control valve II 111, and closing the control valve I106;
at this time, the lower sealing strip 203 and the upper sealing strip 103 are tightly attached to the outer wall of the natural gas pipeline under the combined action of the second connector 202 and the first connector 102, and cooperate with the reinforcing sealing edge 204 to separate the inside of the detection cylinder from the outside, so as to form a closed space;
then, the air pump 112 pumps air in the detection cylinder so that the air pressure in the detection cylinder is lower than the atmospheric pressure in the normal temperature state; for five to ten minutes, the pressure change inside the detection cylinder is observed by the pressure sensor 109; if the pressure in the cylinder is continuously increased, the gas leakage at the joint of the natural gas pipeline is detected; otherwise, no air leakage occurs;
to ensure the working stringency of the device, two additional operating steps are possible:
1. before the air extraction detection, the air pressure in the detection cylinder is the same as the normal temperature atmospheric pressure, the air extraction work is not carried out, and the pressure sensor detection 109 is directly connected to observe the pressure change in the detection cylinder; if the pressure in the cylinder is continuously increased, the gas leakage at the joint of the natural gas pipeline is detected; otherwise, no air leakage occurs; if the pressure of the temporal part of the cylinder is detected and small-amplitude up-down fluctuation occurs, the tightness of the device is problematic, and the reinforced sealing edge 204, the upper sealing strip 103 and the lower sealing strip 203 should be detected;
2. after the air extraction detection, air can be injected into the detection cylinder through the air pump 112, the air pressure in the detection cylinder is increased, the air pressure in the detection cylinder reaches two to three times of the standard air pressure in the natural gas pipeline, the air pressure lasts for five to ten minutes, and the pressure change in the detection cylinder is observed through the pressure sensor 109; if the pressure in the detection cylinder is continuously reduced, the gas leakage is caused at the joint of the natural gas pipeline; otherwise, no air leakage occurs;
note that: in the above process, if the air pressure in the detection cylinder changes rapidly, the problem of air tightness of the device should be considered, the air leakage position of the detection cylinder can be determined by closing the second control valve 111, opening the first control valve 106, injecting water flow into the detection cylinder through the flat pressure pipe 105, and observing the exudation of the water flow; after the flat pressure tube 105 is used for detecting air suction or inflation of the detection cylinder, the first control valve 106 is opened, so that the air pressure in the detection cylinder is quickly balanced with the external air pressure, and the whole device is convenient to use.
