Abstract
The utility model relates to a double-grade anti-theft cipher code sampling valve, which is composed of an oil passing quarter bend, an anti-theft sampling valve, a sampling short segment, an anti-theft code lock and a key. A horizontal straight pipe section is arranged at the left end of the oil passing quarter bend, the diameter at the middle right section of the straight pipe section is large, the diameter at the middle left section of the straight pipe section is small, a vertical code lock cylinder is arranged on the peripheral side of the middle right section, a lock core is arranged at the upper part of the lock cylinder, an anti-theft sampling pressure cap is vertically arranged at the middle part of the lock cylinder, and is connected with the anti-theft sampling valve body through thread. The left end of the anti-theft sampling valve body is designed as an outlet opening, the right end is designed as an inlet opening, a sampling short segment which extends out the middle left section body of the straight pipe section of the oil passing quarter bend is connected at the outlet opening end through a bend and is welded with the outlet opening end, the straight pipe section of the oil passing quarter bend is welded with the oil outlet pipe of a producing brake, and the lower end of the bend is welded with the oil outlet pipe at the upper part of the pressure returning valve. The double-grade anti-theft cipher code sampling valve is provided with the double-grade anti-theft mechanisms, namely, the code lock and an anti-theft switch valve, thus the problem that the lawbreaker can stole the oil at the part of the well top sampling valve can be drastically solved, and the loss of the crude oil in the oil field can be avoided.
