Description

Waterproof special test box of city gas

Technical Field

The utility model relates to a gas test box technical field specifically is a waterproof special test box of city gas.

Background

The urban gas test well is pre-buried in urban road, and its well head height flushes with ground, relies on well lid self weight and around rubber circle sealed, survey the interior survey test panel of well and be naked state. In the in-service use, because the road surface often has the vehicle to pass through, when the vehicle rolled the well lid, because the atress is inhomogeneous, the sealing performance of well lid reduced, and the periphery can produce the gap when the vehicle passes through, leads to the road surface ponding to flow into the test well, and long this is past, and ponding is amasss more in the well, finally leads to the interior survey test panel of well to be submerged, and on-board pipeline connecting wire is short circuit to ground to make the pipeline cloudy current loss of protecting, bury ground pipeline corrosion with higher speed.

Therefore, in view of the above current situation, there is an urgent need to develop a special waterproof test box for city gas to overcome the shortcomings in the current practical application.
