A new type of anti-theft valve to "fuel consumption child" helpless. Since the application in June this year, a crude oil stolen incident has not occurred in the oil well of the first oil production plant of Dagang Oilfield. Because some well locations are in remote areas, the first oil production plant adopts the single-well installation of pull oil tank technology. The crude oil is temporarily stored in the pull oil tank after the formation is stranded, and is pulled by the tanker after the full tank is full. During the storage of crude oil in a storage tank, it is easy to become the target of criminals to commit theft and cause economic losses to the oilfield. The traditional method of using anti-theft oil will be used to pull the oil gate locked with other methods, but still failed to solve the problem of stolen oil tanker stolen. In response to this situation, a production plant engineering system technical staff after careful study and repeated research, and actively introduce the application of a new type of anti-theft valve. The valve in the original pull oil tank to pull the valve function, the installation of a special device, this device without a special unlocking tool in the case can not be opened, so as to achieve the purpose of anti-theft.
