Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention;
Fig. 2 is the structural representation of valve of the present invention.
The specific embodiment
With reference to Fig. 1-Fig. 2, a kind of well head mobile anti-theft device comprises the four-way 4, tubing head 3, total valve 2, the production valve 1 that connect in turn on the casing head 7, and clip 5, sleeve valve 6 and special spanner 15 are installed on the four-way 4.Described total valve 2, produce valve 1 and sleeve valve 6 and be the theft-proof type structure, it comprises the spool 10 and the valve rod 9 that is connected with spool 10 of valve body 8 and interior installation thereof, fixed disk 13 is installed on the valve body 8 in turn and opens valve disc 14, valve rod 9 tops are passed fixed disk 13 and are opened valve disc 14, the top of valve rod 9 with open valve disc 14 and fixedly connected, the last plane of these fixed disk 13 cylindricals is provided with lockhole 16, the last plane of opening valve disc 14 nearly cylindricals is provided with locating hole 12, the lower plane of opening valve disc 14 cylindricals be provided with fixed disk 13 cylindricals on the last lockhole 16 corresponding lockholes 17 down on plane, movable magnetic column 11 is installed in last lockhole 16 and the following lockhole 17 corresponding inner chambers, uses special spanner 15 to be superimposed upon out on the valve disc 14 and open or valve-off.
Wherein, described last lockhole 16 is made as 3-10, and wherein at least 1 last lockhole 16 inner bottom part is inlaid with magnetic conductor 20.Described locating hole 12 is made as 2-5.Described lockhole 17 is all corresponding with the quantity and the position of last lockhole 16 down, and wherein at least 1 following lockhole 17 and last lockhole 16 inner bottom parts are inlaid with magnetic conductor 20.Described special spanner 15 is fixedly connected with the disk structure of handle 21 for the side, its inside is inlaid with permanent magnet 18, the quantity of this permanent magnet 18 and position all with open valve disc 14 on following lockhole 17 corresponding, special spanner 15 cylindrical lower planes are provided with pin 19, and the quantity of this pin 19 and position are all corresponding with the locating hole 12 on opening valve disc 14.Described total valve 2, the mode that is connected and fixed of producing valve 1 and sleeve valve 6 be clip fixedly connected, be welded to connect or be threaded.
Install and use when of the present invention, the upper and lower side of the magnetic column 11 in last lockhole 16 and the following lockhole 17 corresponding inner chambers is a magnetic pole, the polarity of each magnetic column 11 can irregularly be placed upside down, and the lower end that magnetic column 11 can be adsorbed on magnetic conductor 10 in the lockhole 16 automatically reaches the upper end of lockhole 17 interior magnetic conductors 20 down; The lower end polarity of the inner permanent magnetic body 18 of special spanner 15 should be provided with according to the upper end polarity of corresponding magnetic column 11 with it, lower end polarity with the following lockhole 17 corresponding permanent magnets 18 that are provided with magnetic conductor 20, should be same polarity with magnetic column 11 upper end polarity, otherwise be heteropolarity.Special spanner 15 lies in out valve disc 14 tops, pin 19 is inserted in the corresponding locating hole 12,18 pairs of magnetic columns 11 of permanent magnet this moment are had an effect, the magnetic column 11 that is adsorbed on down in the lockhole 17 is pushed, the magnetic column 11 that is adsorbed on lockhole 16 bottoms is picked up, at this moment, all magnetic columns 11 all rest in the last lockhole 16 or following lockhole 17 that does not have magnetic conductor 20, pulling handle 21 can open or valve-off, take special spanner 15 behind the valve closing away, magnetic column 11 can automatically reply original position again, and promptly being equivalent at fixed disk 13 and opening has increased Xiao's bolt between the valve disc 14, thereby pins valve.Because the quantity of magnetic column 11 and permanent magnet 18 and the variation of polarity are of a great variety, so the present invention has more powerful theftproof performance.Fixed disk 13 described in the present invention, open valve disc 14 and special spanner 15 all should adopt the non-magnet material manufacturing.
