Description
Technical field: the utility model relates to oilfield anti-theft technique, especially a kind of oil well casing guard against theft oil steals device of air.
Background technology: in the oily district environment of complexity, lawless person often steals gas from sleeve pipe stolen, not only brings larger economic loss to enterprise, adds very large workload also to the daily management maintenance work of oil well simultaneously.In oil well daily management maintenance work in the past, in order to prevent lawless person from stealing gas from sleeve pipe stolen, generally take following several method: one is be welded after being tightened by sleeve pipe plug.
Two is be welded with Anti-theft cover on boot band head.Three is at well head dress theft-proof box.Four is install all kinds of screws valve for preventing illagel application additional on boot band head.
Although above several method is stolen in gas in guard against theft oil and is served certain effect, but in the management of oil well regular maintenance, there is following shortcoming: one is in the daily pressure measurement of normal producing well, diagnosis, dosing, heat such as to wash at the management work, the class of needing repairing opens after institute's welding wire blocks up with fiery welding and constructs, need often change plug or block ancient head, workload is large, and waste of material is serious.If two is that screws valve for preventing illagel application special spanner is lost or copied by lawless person, then lose the effect of screws valve for preventing illagel application.Three is lawless persons cuts open plug weld bond stolen with fire weldering or other instruments and steals gas.
Summary of the invention: a kind of oil well casing guard against theft oil that the purpose of this utility model is to provide structure simple, easy to operate steals device of air, which overcome the shortcoming of current technology, the purpose of this utility model realizes like this, it be by short circuit, spring fix pit, fuel feed hole, connection internal thread, spring, one end with spring fix pit valve block, with externally threaded joint, hoop, be formed by connecting with the oil pipe short circuit of trapezoidal thread, gas channel, one end of hoop is connected by joint with short circuit, and the other end of hoop is connected with oil pipe short circuit; Have gas channel in the centre of hoop, joint is connected to one end of hoop by external screw thread; Fixing pit internal fixtion in short circuit spring, and the other end of spring is fixed on valve block; Uniform the hole of 10 ￠ 10 around the tube wall of short circuit; One end of valve block is provided with fixing pit; Joint is provided with external screw thread.One end inwall of hoop is provided with trapezoidal left-handed button.
Application process of the present utility model is: pipe casing antitheft device is the operating principle utilizing ball-and-seat, be connected with hoop at the pipe nipple of hoop steel ring side processing tyre screw thread, and around pipe nipple tube wall the hole of uniform 10 ￠ 10, an in-built 1.5Mp spring and a valve block, utilize the pressure on top surface amount of spring, make valve block Sealed casing pipe hoop, reach the not outer object of rushing down of oil gas in sleeve pipe.The opposite side inwall screw thread of hoop is processed into trapezoidal left-handed button, and another processing one is the tubing nipple of trapezoidal left-handed button, and back down inner side valve block by controlling precession tubing nipple length, reach the object of construction, precession length can free adjustment.If sleeve gate damages or is not closed completely, by controlling precession tubing nipple length, reach the object controlling oil gas flow.
Meaning of the present utility model is: 1, this device has one-way flow performance, and sleeve pipe oil gas cannot be leaked; 2, this device makes simple, and easy to operate, processing cost is low; 3, this device anti-theft is good, not easily copies, use safety; 4, this device is owing to using the spring top pressure of 1.5Mp, though sleeve pipe liquid level well head or casing gas large, as stolen gas cannot be stolen without special tool lawless person.5, after this device once mounting, without the need to employing the weldering of electricity fire in regular maintenance management, decreasing workload, having saved cost of materials.Meanwhile, this device can be contained on sampling gate, prevent lawless person from draining the oil from sampling gate after improving.
Accompanying drawing illustrates: Fig. 1 is the structural representation of short circuit, in figure 1, short circuit 2, spring 3, valve block.
Fig. 2 is the structural representation of hoop, in figure 4, joint 5, hoop.
Fig. 3 is the schematic diagram of oil pipe short circuit, in figure 6, oil pipe short circuit.
Detailed description of the invention: embodiment 1, the utility model are formed by connecting by short circuit 1, spring 2, valve block 3, joint 4, hoop 5, oil pipe short circuit 6, and one end of hoop 5 is connected by joint 4 with short circuit 1, and the other end of hoop 5 is connected with oil pipe short circuit 6; Joint 4 is connected to one end of hoop 5 by external screw thread; Fixing pit internal fixtion in short circuit 1 spring 2, and the other end of spring 2 is fixed on valve block 3.
Embodiment 2, there is gas channel in the centre of hoop 5.
Embodiment 3, around the tube wall of short circuit uniform the hole of 10 diameter 10mm.
One end of embodiment 4, valve block 3 is provided with fixing pit.
Embodiment 5, joint 4 are provided with external screw thread.
One end inwall of embodiment 6, hoop 5 is provided with trapezoidal left-handed button.
