Abstract
The utility model provides an anti-theft screwed plug and belongs to a screwed plug used for oilfield production. The anti-theft screwed plug is provided with a screwed plug body, wherein a square hole baffle is fixed on the front portion of the screwed plug body, a square pillar is arranged in the square hole baffle, a circular pillar is arranged in the inner side of the square pillar, a protruded baffle ring is arrange in the inner side of the circular pillar, and a first spring is arranged between the baffle ring and the inner wall of the square hole baffle. The anti-theft screwed plug can be demounted only by utilizing special tools and has the advantages of being good in anti-theft performance, reasonable in structure, not prone to being damaged, and convenient to operate.
Description
Technical field
The utility model provides a kind of plug, especially a kind of plug for field produces.
Background technology
In the oil exploitation industry, Oil/gas Well and pipeline are positioned at the field and comparatively disperse, and management difficulty is large, and the lawless person can back out surface choke cover plug or main line shutoff plug theft crude oil, and this can cause crude oil loss and environment pollution.For this reason, there is at present multiple screws valve for preventing illagel application to be applied.These plugs mainly adopt the box mortice lock structure form, although anti-theft effect is better, but also there is simultaneously larger problem, lawless person theft does not become and can sabotage, in lockhole, fill in foreign matter after, the operational administrative personnel also can't open, can only take electric gas cutting and welding to change, increase danger coefficient, affected normal production, increased workload.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of screws valve for preventing illagel application, to improve its theftproof performance and to make it be difficult for being damaged.
The utility model is achieved in that screws valve for preventing illagel application, and it has the plug body, plug body front portion is fixed with the square hole baffle plate, in the square hole baffle plate square column is installed, and there is cylinder the square column inboard, there is the baffle ring of projection the cylinder inboard, between baffle ring and the square hole baffle inner wall the first spring is installed.
Adopt the screws valve for preventing illagel application of said structure, only have the special tool of use just can finish dismounting, theftproof performance is good, and is rational in infrastructure, is difficult for being damaged, easy to operate.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the left pseudosection of Fig. 1.
Fig. 3 is a kind of structural representation for special tool of the present utility model.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies the utility model.
As shown in drawings, the screws valve for preventing illagel application of the utility model, it has plug body 1, plug body front portion is fixed with square hole baffle plate 2, and square column 3 is installed in the square hole baffle plate, and there is cylinder 5 the square column inboard, there is the baffle ring 4 of projection the cylinder inboard, and the first spring 6 is installed between baffle ring and the square hole baffle inner wall.
Square column, cylinder, baffle ring are made one.
As shown in Figure 3, be used on the special tool of the present utility model bearing 12 being arranged, there is motion bar 16 at the bearing middle part, the outer end of motion bar is fixed with pressure cap 15, the inner is fixed with magnet 9 by screw 10, there is respectively swing handle 11 both sides of bearing, on the bearing in the magnet outside cavity 7 is arranged, the hole slot 13, the other end that have an end of square shrinkage pool 8, the second springs 14 to be positioned on the bearing in the cavity are positioned at the pressure cap inboard.The size of square shrinkage pool is corresponding with the size of square column.The outside dimension of cavity is corresponding with the internal diameter size of the plug body in the square hole baffle plate outside.
Under the original state, the square column outer face is parallel with the lateral surface of square hole baffle plate.When dismounting plug body, the cavity on the bearing is inserted in the plug body in square hole baffle plate 2 outsides, rotating stand makes square shrinkage pool align with square column.By pushing away motion bar, magnet before the pressure cap, make magnet press close to square column, it is held.Draw motion bar outward, the elastic force that makes square column overcome the first spring outwards moves, and square column is passed the square hole baffle plate and entered in the square shrinkage pool, at this moment, by the swing handle rotating stand, just can drive whole plug by square column and rotate, and finishes the dismounting of plug.After this, pull out bearing, magnet and square column are broken away from, square column etc. are got back to original position under the elastic force effect of the first spring.
