Petroleum products pipeline leakage control device

Abstract

The invention relates to a pipeline leakage control device for implementing control after products pipelines leaked, which is composed of a pedrail walking system [4], an exerting system, a barrier clearance supporting system [8], a leaked oil recover device [1], a cable take-up and payoff system [10], a supporting platform system [9], a hydraulic system [6], an electrical control system [7], a remote control system [11] and a monitoring system [5]. The pedrail walking system [4] is positioned below the supporting platform system, above which, the hydraulic system [6], the electrical control system [7], the cable take-up and payoff system [10], the leaked oil recover device [1], the barrier clearance supporting system [8] and the exerting system are respectively arranged; wherein, the hydraulic system [6] is connected with the cable take-up and payoff system [10] through cables; signals of the remote control system [11] are sent to the electrical control system [7] controlling the hydraulic system [6], the pedrail walking system [4], a small movable arm [2] and a big movable arm [3] as well as the leaked oil recover device [7]; while signals of the monitoring system [5] is transferred to the remote control system [11] through the cable of the cable take-up and payoff system [10].

Description

technical field [0001] The invention is a pipeline leakage control device for controlling the leakage of a product oil pipeline. It relates to the technical field of piping systems. Background technique [0002] Leakage control is an important means to prevent accidents from expanding and reduce accident losses. Once a product oil pipeline leaks, even if it is necessary to stop the transmission and close the line shutoff valves upstream and downstream of the leak point, since the oil pipeline is not on the same level, as long as the leak point is not at the highest point of the cut off pipeline section, there will be an elevation If there is a difference, the leak point will spray oil outward due to the static pressure of the pressure difference. When the static pressure reaches a certain level, it will break through the soil layer and spray into the air, which is often the case. The result is not only waste, but also pollute the environment, the consequences are extremel...

The result is not only waste, but also pollute the environment, the consequences are extremely serious

And once this happens, according to the current technology, the emergency repair personnel not only cannot get close to the injection site, but also because of the high injection pressure, it is impossible to cover the drainage cover with manual force, let alone block it, so they have to let the oil Repair after spraying
