Abstract
An antitheft wellhead shifter comprises a cross joint, an oil pipe joint, a main valve and an operating valve which are connected on a sleeve head sequentially, wherein a collar clamp and a sleeve valve are mounted on the cross joint. The antitheft wellhead shifter is characterized in that the main valve, the operating valve and the sleeve valve are in antitheft structures, each antitheft structure comprises a valve body and a nut in threaded connection with the valve body, a valve stem connected with a valve spool is arranged in the nut, an antitheft cover is arranged on the nut, the valve steam is coated by the antitheft cover integrally, and a square angle is arranged at the outer end of the valve stem. The valves can be turned on and off by special switch spanners. Compared with the prior art, the antitheft wellhead shifter has the advantages of simple structure, convenience in use, low cost, long service life and capability of leading the valves to be opened by staff only.
Description
One, technical field
The utility model relates to the valve for guarding against theft technical field, is specifically related to the antitheft mobile device of a kind of well head.
Two, background technology
Existing various valve has types such as gate valve, ball valve, butterfly valve, commentaries on classics core valve and stop valve.The valve of these numerous kinds all adopts rotating circular disk or rotation tommy bar mode to carry out switch; Its structure is for being equipped with spool in valve body, spool connects and has externally threaded valve rod, and valve rod stretches out valve body and is rotatably assorted with valve body, and the valve rod outer end is equipped with rotating disk or the handle that is used for switch; Rotary turnplate or pull handle promptly can drive valve rod and valve core rotation, thus controlled valve.Though this valve is simple in structure, easy to use, remaining is having following defective or deficiency: 1, spool adopts common material, and spoilage is higher; When 2, valve was installed in the field, as on the oilfield well head time, the inoperative personnel can arbitrarily operate its switch, so crude oil theft and so on incident happens occasionally.Even lay down rotating disk or handle, other people also can utilize the common wrench Open valve, cause damage to the user, can have an accident when serious, and influence is produced.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of antitheft mobile device of well head that can stop other people switch is provided.
Its technical scheme is: comprise the four-way, tubing head, total valve, the production valve that connect in turn on the casing head, clip, sleeve valve are installed on the four-way.Described total valve, production valve and sleeve valve are the theft-proof type structure, and it comprises valve body and the nut that is threaded with it, is provided with the valve rod that is connected with spool in the nut; Described valve body top nut is provided with antitheft cover, antitheft cover parcel valve rod integral body, and the outer end of valve rod is provided with corner.
Wherein, described antitheft cover is the cylindrical member of being made by strong magnetic material, and the nut on one end and the valve body connects, and the other end is provided with removable cover.The corner of described valve rod outer end is outer triangle side, outer four jiaos of sides, outer five jiaos of sides or outer-hexagonal sides.
The utility model has simple in structure, easy to use, with low cost and can effectively prevent the advantage of inoperative personnel controlled valve compared with prior art.
Four, description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of valve among Fig. 1.
Five, the specific embodiment
With reference to Fig. 1, the antitheft mobile device of a kind of well head 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 are installed on the four-way 4.Described total valve 2, production valve 1 and sleeve valve 6 are the theft-proof type structure,
With reference to Fig. 2, the nut 9 that the structure of total valve 2, production valve 1 and sleeve valve 6 comprises valve body 8 and is threaded with it is provided with the valve rod 10 that is connected with spool 13 in nut 9; Described nut 9 is provided with antitheft cover 11, antitheft cover 11 parcel valve rods 10 integral body, and the outer end of valve rod 10 is provided with corner.Wherein, described antitheft cover 11 is the cylindrical member of being made by strong magnetic material, and one end and nut 9 connect, and the other end is provided with removable cover 12.The corner of described valve rod 10 outer ends is outer triangle side, outer four jiaos of sides, outer five jiaos of sides or outer-hexagonal sides.
When controlled valve, undertaken by the special switch spanner.Be overall structure or dispersion packing after this device is made, when installing and using, can wholely move, be installed to oil well whenever and wherever possible, can also adjust at any time or mobile each position component according to the scene, to be adapted to field requirement.
